Description

  The present invention relates to a medical chemical application tool to which a chemical liquid application member made of a porous body made of a foamable synthetic resin material such as a sponge can be attached, and a grip handle thereof.

  Made of urethane that impregnates the tip of a grip handle made of thermoplastic resin material such as plastic as a medical device for applying a chemical solution such as a disinfectant solution to an affected part (medical treatment part) of a patient in a medical field Development of a chemical applicator (sponge with a handle) to which a chemical liquid applicator member made of a porous material such as a polyethylene or cellulose sponge is attached is underway.

  Such a sponge with a handle should be easier to operate than the previous work of applying chemicals by sandwiching sponges made of gauze impregnated with chemicals, cotton balls, urethane, polyethylene and cellulose with tweezers. If a lint such as sponge or the like is used or suppressed, lint cannot be avoided due to its nature when using a cotton ball, and it can be used for disinfecting parts such as shaved parts and instruments used. Since it is not necessary to pay attention so that lint does not adhere, it is expected to be excellent in the urgency of the treatment and perform the chemical liquid application operation simply and accurately.

  As a method of attaching a chemical solution application member with a sponge made of urethane, polyethylene, or cellulose to a grip handle made of synthetic resin, a slot-like rift is formed in the center of the chemical solution application member, and so on. A method is conceivable in which the tip of the gripping handle is inserted and the chemical solution applying member is fixed to the gripping handle by ultrasonic, high frequency, or heat fusion using a heating body.

In addition, as a chemical solution applicator for applying a chemical solution to the skin, a spherical chemical solution absorbent material is fitted into a hemispherical recess formed on the handle member, and the chemical solution absorbent material is fixed to the handle member by an adhesive or caulking. There is (for example, Patent Document 1).

  Sponge with handle for applying chemical solution is superior in absorption of chemical solution, etc., and uses sponge etc. (chemical solution application member) that can be applied evenly, and has higher reliability compared to household equivalent products for gripping handle such as sponge And reliability are required.

  In particular, those that are used for preoperative disinfection at the time of surgery and disinfection of post-surgical sutures are strongly required for these, impregnated with chemicals etc., exhibiting the liquid absorption function that the sponge can have, By increasing the weight of the chemical solution, or by a chemical solution (disinfectant) or the like, the fixing strength of the sponge and the grip handle is weakened, and it is necessary to have high reliability that the sponge does not fall off from the handle handle during use.

  On the other hand, it is considered that the fixing (fixing) of the chemical solution application member by heat fusion satisfies these conditions. However, the fixing (fixing) of the chemical solution application member by heat fusion requires a heat fusion facility, and may further require a step of preliminarily attaching the chemical solution application member to the grip handle. For this reason, equipment costs and manufacturing time tend to increase, and it is difficult to reduce manufacturing costs. This is a sticking (fixing) method that is not suitable in terms of cost since a cheap sponge with a handle for disposable use is required.

  In addition, when a sponge is impregnated with an alcohol-based antiseptic solution as a chemical solution for sterilization treatment at a medical site, the strength of fixing to the gripping handle is weakened, and the sponge may come off the gripping handle. The handle sponge fixed by wearing could not be actively used for impregnation with alcohol-based disinfectant.

  The problem to be solved by the present invention is that in a medical chemical liquid applicator called a sponge with a medical pattern, it is highly resistant to falling off with respect to the fixation (fixation) of the chemical liquid application member to the gripping pattern without thermal fusion. Is to gain reliability.

  The chemical solution applying member 10 is formed with a bottom slit-shaped cut 12 having a cut surface on the bottom surface 11. The bottom slit-shaped notch 12 has a length La equal to or less than the width W of the chemical solution applying member 10 and a depth Da equal to or less than the length H of the chemical solution applying member 10, but at this time, the width W and the length of La are the same. When the depth Da is shorter than the length H, or when the depths Da and H are the same length, the length La must be shorter than the width W.

  The grip handle 20 only needs to have a grip portion 21 to be gripped by the user's hand, a strip-shaped piece portion 22 to which the chemical solution applying member 10 is attached, and a pair of sandwiching piece portions 23, and is particularly limited. For example, polypropylene (PP), polystyrene (PS), polycarbonate (PC), polyacetal (POM), polymethyl methacrylate (PMMA), polyamide (PA), acrylonitrile / butadiene / styrene Polymer (ABS), acrylonitrile / styrene copolymer (AS), vinyl chloride (PVC), polycarbonate (PC), polyacetal (POM), polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polycarbonate (PC), Modified polyphenylene ether (PPE), polyphenyle Sulfide (PPS), polyetheretherketone (PEEK), liquid crystal polymer (LCP), polytetrafluoroethylene (PTFE), polyfluoroalkoxy (PFA), polyetherimide (PEI), polyamideimide (PAI), polyarylate ( PAR), polysulfone (PSF), polyethersulfone (PES), hard vinyl chloride, and a resin molded article composed of a synthetic resin such as a reinforced resin in which glass fibers are mixed into the resin material.

  The length and thickness of the grip handle 20 and the grip portion 21, the strip-shaped piece portion 22, and the sandwiching piece portion 23 may be appropriately selected in consideration of the intended use. Moreover, the thickness of the clamping piece part 23 becomes like this. Preferably it is about 1 mm-5 mm, More preferably, it is about 1.5 mm-3.0 mm.

  The grip portion 21 is plate-shaped, and more preferably has depressions 24 formed on both sides, and has a bowl-shaped cross-sectional shape that is easy to be gripped. In order to further ensure the rigidity of the gripping handle 20 as a whole, the plate surface of the gripping portion 21 and the plate surface of the strip-shaped piece portion 22 may be rotated and displaced by 90 degrees.

  The strip-shaped piece 22 is located at the tip of the side opposite to the gripping portion 21 and is inserted into the bottom slit-shaped cut 12 formed in the chemical solution application member 10, thereby holding the chemical solution application member 10. The insertion amount of the chemical solution applying member 10 with respect to the belt-like piece portion 22 is uniquely defined by the bottom surface 11 of the chemical solution applying member 10 coming into contact with a rectangular insertion restriction rod 25 formed in the belt-like piece portion 22.

  The sandwiching piece portions 23 are paired on both the front and back sides of the strip-shaped piece portion 22, and the base ends are hinged to the front and back surfaces of the intermediate portion on the gripping portion 21 side from the strip-shaped piece portion 22 by the hinge connecting portion 26. Has been. The hinge connecting portion 26 for the band-like piece portion 22 of the sandwiching piece portion 23 is thinner than the plate thickness of the other portion and forms a foldable resin hinge.

  On the plate surface where the pair of sandwiching piece portions 23 are opposed to the strip-like piece portion 22, locking pieces 27 are formed so as to protrude from each other. The locking piece 27 has a check-shaped claw portion 28 at the tip. A claw portion 29 to which the claw portion 28 can be non-returnably engaged is formed on the surface of the insertion restriction rod 25 on the gripping portion 21 side. A reinforcing plate portion 31 that defines the entry groove 30 of the locking piece 27 is formed slightly closer to the gripping portion 21 than the insertion restriction rod 25 of the strip-shaped piece portion 22.

  As shown in FIG. 1 and FIG. 2, the locking piece 27 is rotated from the opened state toward the band-shaped piece portion 22 with the hinge connection portion 26 as the rotation center, as shown in FIGS. 1 and 2. As a result, it enters the entry groove 30, and the claw portion 28 of the locking piece 27 engages with the claw portion 29 of the insertion restriction rod 25 in a non-return engagement. This state is shown in FIG. 3, and this state is called a check engagement state.

  In the non-reverse engagement state, the pair of sandwiching piece portions 23 are substantially parallel to the strip-shaped piece portion 22, respectively, and the side of the bottom surface 11 of the chemical solution applying member 10 inserted into the strip-shaped piece portion 22 is disposed on the strip-shaped piece. The both sides of the part 22 are sandwiched between the strip-shaped part 22 and the chemical coating member 10 is clamped in a sandwiched manner.

  In the check engagement state between the claw portion 28 of the locking piece 27 and the claw portion 29 of the insertion restriction rod 25, the locking piece 27 enters the entry groove 30 and the back side of the locking piece 27 (return lock) Since the displacement to the side from which the engagement is separated is prevented by the reinforcing plate portion 31, once the claw portion 28 of the locking piece 27 is reversely engaged with the claw portion 29 of the insertion restriction rod 25, It does not come off and the clamping clamp of the chemical coating member 10 is not released.

  A triangular non-return shaped portion 32 having a sharp tip when viewed from the side is formed on both front and back surfaces of the front end side of the belt-like piece portion 22, and the front end side of the belt-like piece portion 22 as a whole has a narrow angle. It has an equilateral triangular arrowhead shape. The non-return shape portion 32 is located on the distal end side of the strip-shaped piece portion 22 from the insertion restriction rod 25 and has an inclined surface portion 33 and a check surface 34 parallel to the insertion restriction rod 25.

  The non-return surface 34 of the non-return shape portion 32 and the insertion restriction rod 25 are provided with a chemical solution application member entering recess 35 having a predetermined length in the insertion direction (vertical direction in the figure) of the chemical solution application member 10. Are defined on both the front and back surfaces of the strip-shaped piece 22.

  The sandwiching piece portion 23 has a length such that the tip (free end) reaches the portion of the check shape portion 32 on the check surface 34 side. The liquid application member entering recess 35 is closed by the clamping piece 23 in the non-reverse engagement state.

  A locking engagement pin 36 is formed so as to protrude in the vicinity of the free end of the surface portion where the sandwiching piece portion 23 faces the strip-like piece portion 22. A conical check portion 37 having a pointed tip is formed at the tip of the locking engagement pin 36. In the vicinity of the check surface 34 of the check shape portion 32, a slot 38 is formed in which the conical check portion 37 of the locking engagement pin 36 is reversely engaged.

  As shown in FIG. 2, the chemical solution applying member 10 is attached to the grip handle 20 in the first embodiment in a band shape in the bottom slit-shaped cut 12 of the chemical solution applying member 10 with the holding piece portion 23 open. Insert the piece 22. This insertion is performed until the insertion restriction rod 25 comes into contact with the bottom surface 11 of the chemical solution application member 10.

  Thereby, the insertion amount of the chemical solution application member 10 with respect to the strip-shaped piece portion 22 automatically becomes a predetermined value, the bottom 11 side of the chemical solution application member 10 gets over the check-shaped portion 32, and a part thereof is a recess that enters the chemical application member. 35 enters the state.

  Next, as shown in FIG. 3, the holding piece portion 23 is rotated to the side of the strip-shaped piece portion 22 with the hinge connection portion 26 as the rotation center, and the locking piece 27 enters the entry groove 30. Then, the claw portion 28 of the locking piece 27 is reversely engaged with the claw portion 29 of the insertion restriction rod 25.

  In this state, the liquid application member entering recess 35 is closed by the sandwiching piece 23, and the bottom 11 side of the chemical application member 10 (the portion over the check shape portion 32) enters the drug application member entering recess 35. In this state, it is sandwiched between the sandwiching piece portion 23 and the strip-like piece portion 22 and clamped in a sandwiching manner.

  Thereby, the chemical solution applying member 10 is deformed following the formation of the non-return shaped portion 32 of the strip-shaped piece portion 22, and in particular, the bottom 11 side of the chemical solution applying member 10 enters the chemical solution applying member entering recess 35. As a result, the chemical solution applying member 10 is firmly attached to the grip handle 20 so as not to come off.

  Further, in this state, the conical check portion 37 of the lock engagement pin 36 breaks through the chemical solution applying member 10 and is engaged in the check with the slot 38, so that the check engagement state of the sandwiching piece portion 23 is established. Further, it becomes more reliable, and the retaining attachment of the chemical solution application member 10 to the grip handle 20 becomes stronger.

  Further, in order to obtain a stronger stopper, the same one as the slot 38 is installed in the recess 35 containing the chemical application member, and a conical check part 37 is attached to the tip so as to correspond to this. What is necessary is just to install the thing similar to the engagement pin 36 in the holding | grip part side rather than the latching engagement pin 36 of a clamping piece part, and the number of expansion may be one set or multiple sets. Moreover, what is necessary is just to expand the chemical | medical solution application member entering recessed part 35 suitably according to this addition number (drawing omitted).

  The medicinal solution application member 10 is mounted on the handle 20, that is, the handle-equipped sponge can be sterilized as a medical medicinal solution applicator and a bag (so-called sterilization bag) that can maintain sterility after sterilization. ) And sealed with a heat seal or the like to be sterilized.

  Sterilization methods include high-pressure steam sterilization method (AC sterilization method), ethylene oxide gas sterilization method (EOG sterilization method), plasma sterilization method, and radiation sterilization method (γ-ray sterilization method and electron beam sterilization method). When the handle 20 is made of polypropylene or polycarbonate, the sealed sterilization bag is optimally sterilized by the EOG sterilization method.

  The chemical solution application member 10 is made of urethane sponge (thickness T is 25 mm, width W is 50 mm, length H is 55 mm), and the grip handle 20 is made of polypropylene. After the EOG sterilization, the plating bag (Hogi Medical Co., Ltd.) The product is taken out from the product and applied with a chemical solution of popiyodon solution (Yoshida Pharmaceutical Co., Ltd., 10% popidone iodine) and 0.5% hexac alcohol solution (Yoshida Pharmaceutical Co., Ltd., 0.5% chlorhexidine gluconate gluconate disinfection solution). When the member 10 was sufficiently impregnated and the antiseptic solution application simulation operation was performed, the chemical solution application member 10 did not come off the grip handle 20 and a stable and excellent antiseptic solution application operation could be performed.

  Embodiment 2 of the grip for medical drug application tools and the medical drug application tool according to the present invention will be described with reference to FIGS. 6 to 8, parts corresponding to those in FIGS. 1 to 5 are denoted by the same reference numerals as those in FIGS. 1 to 5, and description thereof is omitted.

  The material, shape, and specifications of the chemical solution application member 10 of the second embodiment are the same as those of the first embodiment except for a side slit-like cut into which a locking piece 42 to be described later is inserted.

  In the second embodiment, even when a so-called soft resin typified by polyethylene (PE) is used, the chemical application member 10 and the gripping handle 20 are firmly fixed, and the soft resin is used in the first embodiment. This prevents the sandwiching piece portion 23 from warping and provides a sufficient gripping ability.

  As described above, the first choice is to use a so-called hard resin as in the first embodiment as a material for the gripping handle if the chemical solution applying member 10 and the gripping handle 20 are firmly fixed. Hard resin is often unsuitable for deterioration such as polypropylene (PP) when sterilized by radiation sterilization. In addition, since the radiation sterilization method does not have the degassing step as in the EOG sterilization method, it can be shipped on the day of sterilization, and has the advantage of being able to respond immediately to customer needs.

  On the other hand, in Embodiment 2, the grip handle 20 is made of polyethylene (PE) having electron beam irradiation resistance so that sterilization after packing of the medical solution applicator can be performed by electron beam irradiation. Yes. Polyethylene is a softer resin than polypropylene, but also in this embodiment, the gripping handle 20 has a shape in which the plate surface of the gripping portion 21 and the plate surface of the strip-shaped piece portion 22 are rotated and displaced by 90 degrees. The strength of can be secured. This prevents the gripping portion 21 from bending more than necessary during use.

  In particular, the electron beam sterilization method does not require treatment of the radiation material as a radiation source, and has advantages in terms of safety and cost as compared with the γ-ray sterilization method.

  The grip handle 20 used in the second embodiment is softened with polyethylene (PE), vinyl chloride, polyethylene (PE), tetrafluoroethylene (FEP), and plasticizer, which are so-called soft resins. Resin (soft vinyl chloride etc.) etc. may be sufficient.

  In the second embodiment, it is desirable that the plate surface of the grip portion 21 and the plate surface of the strip-shaped piece portion 22 have a shape that is rotated and displaced by 90 degrees with each other to ensure the strength of the grip handle 20. This prevents the gripping portion 21 from bending more than necessary during use.

  In the second embodiment, instead of the locking engagement pin 36, a locking piece 42 having a check-shaped claw portion 41 at the tip is formed to protrude. A claw portion 43 to which the claw portion 41 can engage in a check is formed on the check surface 34 of the check shape portion 32. A protrusion 44 is formed on the side of the insertion restricting rod 25 from the check surface 34 of the check shape portion 32, and a locking piece is formed by the end surface 45 of the protrusion 44 and the check surface 34 of the check shape portion 32. 42 entry grooves 46 are defined.

  As illustrated in FIG. 8, the chemical solution applying member 10 used in the second embodiment is formed with side slit-shaped cuts 13 into which the locking pieces 42 are inserted on both front and back surfaces.

  As shown in FIG. 6, the attachment of the chemical solution applying member 10 to the grip handle 20 in the second embodiment is a belt-like shape in the bottom slit-shaped notch 12 of the chemical application member 10 with the holding piece portion 23 being open. Insert the piece 22. This insertion is performed until the insertion restriction rod 25 comes into contact with the bottom surface 11 of the chemical solution application member 10. Thereby, the insertion amount of the chemical solution applying member 10 with respect to the strip-shaped piece portion 22 naturally becomes a predetermined value, and the bottom portion 11 side of the chemical solution applying member 10 gets over the check shape portion 32.

  Next, as shown in FIG. 7, the holding piece portion 23 is rotated to the side of the strip-shaped piece portion 22 with the hinge connection portion 26 as the rotation center, and the locking piece 27 enters the entry groove 30. Then, the claw portion 28 of the locking piece 27 is reversely engaged with the claw portion 29 of the insertion restriction rod 25.

  Thereby, the chemical solution applying member 10 is deformed following the formation of the check shape portion 32 of the strip-shaped piece portion 11, and in particular, the side portion of the bottom portion 11 of the chemical solution applying member 10 gets over the check shape portion 32, and the protruding portion 44 is in contact.

  Furthermore, in this state, the locking piece 42 is inserted into the side slit-shaped cut 13 of the chemical solution applying member 10, penetrates through this, and enters the entry groove 46. It engages with the claw portion 43 of the check shape portion 32 in a check manner. As a result, the non-return engagement state of the sandwiching piece portion 23 is further ensured, and the attachment of the chemical solution applying member 10 to the grip handle 20 is further strengthened.

  In the present embodiment, in the non-return engagement state of the claw portion 41 of the locking piece 42 and the claw portion 43 of the check shape portion 32, the locking piece 42 enters the entry groove 46, Displacement to the back side (the side from which the non-return engagement is disengaged) is prevented by the protrusion 45, so that the claw portion 41 of the locking piece 42 is temporarily separated from the claw portion 43 of the check shape portion 32. When the non-return engagement is performed, it does not come off, and the sandwiching clamp of the chemical coating member 10 is not released.

  In the case where it is required to attach the chemical liquid application member 10 to the grip handle 20, it is the same as the protrusion 44, the entrance groove 46, the claw portion 43, and the end face 45 in order from the grip portion direction to the position of the entrance groove 46. A thing similar to the locking piece 42 with the claw part 41 attached to the tip thereof is installed closer to the gripping part than the locking piece 42 of the sandwiching piece so as to correspond to this, and the chemical application member The side slit-shaped cuts 13 may be added to the number 10, and the number of extensions may be one set or a plurality of sets.

  The chemical solution applying member 10 is made of urethane sponge (thickness T is 25 mm, width W is 50 mm, length H is 55 mm), and the grip handle 20 is made of polyethylene. ) Removed from Hogi Medical), Popiodon solution (Yoshida Pharmaceutical Co., Ltd., 10% popidone iodine solution) and 0.5% Hexac alcohol solution (Yoshida Pharmaceutical Co., Ltd., 0.5% Chlorhexidine Gluconate Ethanol Disinfection Solution) ) Was sufficiently impregnated into the chemical solution application member 10 and the disinfection solution application simulation operation was performed. As a result, the drug application member 10 did not come off the gripping handle 20, and a stable and excellent disinfection solution application operation could be performed.

  Embodiment 3 of the handle for medical medicinal liquid applicator and the medical medicinal liquid applicator according to the present invention will be described with reference to FIGS. 9 to 12, portions corresponding to those in FIGS. 1 to 5 are denoted by the same reference numerals as those in FIGS. 1 to 5, and description thereof is omitted.

  In the third embodiment, since the material, shape, and specifications of the chemical solution applying member 10 are the same as those in the first embodiment, the description thereof is also omitted. The medical liquid applicator of this embodiment is composed of a urethane liquid chemical liquid applying member 10 and a polyethylene gripping handle 20.

  Similarly to the second embodiment, the third embodiment is similar to the second embodiment, even when a so-called soft resin typified by polyethylene (PE) having a radiation sterilization method (particularly electron beam irradiation resistance) is used, the chemical solution application member 10 and the grip handle 20 is firmly fixed, and the slit to be cut into the chemical solution applying member 10 is only the bottom slit-like cut 12 (the side slit-like cut is unnecessary).

  Since the non-return engagement between the claw portion 41 of the locking piece 42 according to the second embodiment and the claw portion 43 of the check shape portion 32 is a very strong engagement, the chemical solution applying member 10 and the grip handle 20 Although it is ideal in fixing, since the side slit-shaped cut is required for the chemical solution applying member 10, if the slit-shaped cut is not necessary, the manufacturing cost can be further suppressed.

  Therefore, in the third embodiment, even if a soft resin is used for the gripping handle, it is sufficient to withstand the use of actual disinfecting liquid application, and it is a cheaper medical liquid applicator that does not require side slit-like cutting. . In the third embodiment, it is desirable that the plate surface of the gripping portion 21 and the plate surface of the strip-shaped piece portion 22 have a shape that is rotationally displaced by 90 degrees from each other to ensure the strength of the grip handle 20. This avoids bending (elastic deformation) of the grip portion 21 more than necessary during use.

  In the third embodiment, the pair of sandwiching piece portions 23 are formed on each plate surface facing the strip-like piece portion 22, and two pressing projections 51 and 52 are formed adjacent to each other with a gap 53. Fine concave and convex shapes 54 and 55 such as lateral serrations are formed on the tip surface portion where the pressing projections 51 and 52 are opposed to the strip-shaped piece portion 22.

  The strip-shaped piece portion 23 is formed with a protruding piece portion 56 that enters the gap 53 between the pressing protrusion portions 51 and 52.

  In the third embodiment, the chemical solution applying member 10 shown in FIG. 5 is used.

  As shown in FIG. 10, the chemical solution applying member 10 is attached to the grip handle 20 in the third embodiment in a band-like shape in the bottom slit-shaped notch 12 of the chemical solution applying member 10 with the holding piece portion 23 open. Insert the piece 22. This insertion is performed until the insertion restriction rod 25 comes into contact with the bottom surface 11 of the chemical solution application member 10. Thereby, the insertion amount of the chemical solution application member 10 with respect to the strip-shaped piece portion 22 naturally becomes a predetermined value, and the bottom portion 11 side of the chemical solution application member 10 gets over the check shape portion 32.

  Next, as shown in FIG. 11, the clamping piece portion 23 is rotated toward the band-shaped piece portion 22 with the hinge connection portion 26 as the rotation center, and the locking piece 27 enters the entry groove 30. Then, the claw portion 28 of the locking piece 27 is reversely engaged with the claw portion 29 of the insertion restriction rod 25.

  In this state, the portion where the chemical solution applying member 10 has climbed over the check-shaped portion 32 is sandwiched between the fine uneven shapes 54 and 55 of the pressing projections 51 and 52 and the strip-shaped piece portion 22 and clamped in a sandwiching manner. The
