Description

  The present invention relates to a medical tray for storing medical supplies.

  In the medical field, before performing diagnosis, inspection, and treatment, medical instruments and drugs necessary for the treatment are set in a sterilized tray, and are taken out from the tray and used for the treatment. In recent years, in order to save the trouble of preparing medical instruments and drugs at the medical site, development of disposable packaging products in which necessary medical instruments and drugs are stored in a tray in advance and sterilized by placing them in a packaging bag has progressed. It is out.

  The tray is used not only for storing a medical instrument or a drug in a treatment using a catheter or a guide wire, but also for making a surface of the catheter, a guide wire or the like wet. Necessary catheters, guide wires and the like are set in the tray according to treatment, and the surface of the catheter and guide wires is wetted by filling the tray with physiological saline and the like.

  In order to obtain such a state of use, when it is not sufficient to use only a tray that stores medical instruments or the like, it is conceivable to stack the trays twice or more to obtain a package product. That is, when using a packaged product at a medical site, it is possible to secure a sufficient area by separating the overlapping trays and separately arranging medical instruments and the like on each tray.

  By the way, since there are cases where a long and elastic medical device such as a catheter is wound around the tray and stored, in order to prevent these from popping out due to the elastic force, An undercut portion is formed by extending a part of the side wall of the tray inward. For this reason, when a plurality of trays are stacked, it takes a lot of time to be caught by the undercut portion and to be separated deeply.

  Furthermore, since the tray used for the package product is disposable, it is usually manufactured from a thin resin. When a plurality of such trays are stacked, even if the trays are to be separated, it is difficult for air to enter between the trays, which makes it more difficult to separate them.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a medical tray that can be easily separated even when a plurality of sheets are stacked, and can reduce a burden on the user.

The medical tray of the present invention that achieves the above object has a bottom portion and a side wall provided along the outer periphery of the bottom portion, and is a medical tray that can be stacked, and is provided at the upper end of the side wall. and was the flange portion, a projecting portion projecting from said flange portion upward, the width of the bottom portion is formed concave inward, and a constricted portion to facilitate inward deformation of the side wall, said projection The portion is a medical tray that has a height that can be disposed on the side of the flange portion of another medical tray that is overlaid, and that forms a gap between the side walls that overlap with each other. The medical tray has a bottom portion and a side wall provided along the outer periphery of the bottom portion and can be stacked, and includes a flange portion provided at an upper end of the side wall, and an upper side from the flange portion. A protruding portion that protrudes toward the upper side of the side wall and is provided adjacent to the protruding portion, and facilitates bending toward the inside of the side wall. It is a medical tray that has a height that can be disposed on the side of the flange portion of another medical tray that is stacked, and that forms a gap between the side walls that overlap with each other.

  The medical tray of the present invention configured as described above has a height at which the protruding portion protruding upward from the flange portion can be disposed on the side of the flange portion of another medical tray that is overlaid, A gap is formed between the overlapping side walls depending on the arrangement, so that air flows in from the gap and the surface resistance between the side walls is reduced, so that the stacked medical trays can be easily separated. Can reduce the burden on

  Further, when the bottom portion is formed to be recessed inward and further has a constricted portion that facilitates deformation to the inside of the side wall, when the upper medical tray is partially grasped and pulled upward. Further, the side wall is deformed inward while air flows in from the gap. As a result, a gap between the overlapping side walls is widened, so that air is more likely to flow in, and the surface resistance between the side walls is further reduced, so that the stacked medical trays can be more easily separated. Become.

  In addition, if a bend guiding portion is provided on the upper side of the side wall adjacent to the protrusion and facilitates bending toward the inner side of the side wall, in the vicinity of the gap formed by the protrusion. The bending guide portion is provided, and when a part of the upper medical tray is grasped and pulled upward, the side wall is bent inward along the bending guide portion while air flows in from the gap. As a result, a gap between the overlapping side walls is widened, so that air is more likely to flow in, and the surface resistance between the side walls is further reduced, so that the stacked medical trays can be more easily separated. Become.

  Further, the bending guide part is formed by a step part formed of a step formed at an upper end of the flange part, a flange groove part formed by recessing the flange part inwardly, and a recess of the side wall inwardly. If it is configured by at least one of the side wall groove portions, bending to the inside of the side wall is locally facilitated.

  In addition, if the protrusions are formed on both side walls facing each other, air efficiently flows in from two relatively spaced gaps, and the stacked medical trays are more It becomes easy to separate. In particular, if a bending guide part is provided adjacent to both protrusions, the bottom part also bends between the two bending guide parts, which makes it easier to widen the gap and improve the separation of stacked medical trays. Can be increased.

  Further, if the protrusion is equal to or greater than the overlapping pitch generated when the medical trays are stacked, the protrusion of the lower medical tray is equal to or higher than the height of the flange portion of the other medical tray, It is possible to satisfactorily maintain the state in which the protruding portion of the lower medical tray is disposed on the side of the flange portion of the upper medical tray.

  Further, if the back surface of the protrusion is configured as a concave portion, the two medical trays can be completely fitted when the treatment is finished and the medical trays are discarded, and the volume of waste is reduced. Can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the dimension ratio of drawing is exaggerated on account of description, and may differ from an actual ratio.

  As shown in FIG. 1, the medical tray 10 according to the embodiment has a side wall 12 formed along the outer periphery of the bottom 11, and a medical instrument such as a catheter 40 (see FIG. 3) is immersed in physiological saline or the like. Thus, it is used for imparting wettability or for arranging medical instruments, and as shown in FIGS. 2 and 3, it is also used as a packaging tray for packaging medical instruments, drugs and the like.

  The medical tray 10 stores necessary medical instruments and medicines in advance, and is provided as a disposable package product in a state of being stored in a packaging bag (not shown). Examples of the medical device include a catheter, a syringe, a guide wire, a sheath, a dilator, scissors, tweezers, absorbent cotton, and a drape.

  The medical tray 10 is made of a thin resin, and is formed by vacuum molding or the like from a thermoplastic resin sheet such as polyethylene, polypropylene, polystyrene, or polyvinyl chloride. It is preferable that the bottom part 11, the side wall 12, the flange part 14, and the projection part 15 are integrally formed.

  When the packaging is unpacked during the procedures such as diagnosis, examination, and treatment, the drape 41 and the like are installed on the medical tray 10 as shown in FIG. Thereafter, as shown in FIG. 3, after the drape 41 and the like on the medical tray 10 are taken out, other medical instruments and the like are further taken out from the medical tray 10. Two medical trays 10 are stacked, and after separating them, a medical instrument is placed again, or a medical instrument such as a catheter 40 that needs to be wet is set on an empty medical tray 10. Then, physiological saline or the like is poured into the medical tray 10, and the medical instrument such as the catheter 40 is moistened.

  As shown in FIGS. 1, 4 and 5, each medical tray 10 includes a bottom portion 11 and side walls 12 which are provided along the outer periphery of the bottom portion 11 and form a storage space in which a medical instrument can be stored together with the bottom portion 11. Have. The bottom part 11 is substantially rectangular (a rectangle with rounded corners, and one side is more rounded than the other side), and the long side is near the center compared to both end sides. It is preferable that a constricted portion (narrow portion) 17 having a narrow width (near line L) is provided. By providing the constricted portion 17, the inner wall 12 can be easily deformed inside. The side wall (peripheral wall) 12 is provided on the entire circumference of the bottom portion 11, and is preferably erected slightly inclined outward from the bottom portion 11.

  A flange portion 14 is formed on the side wall 12 so as to project from the side wall 12 to the side (outward from the side wall 12, that is, a direction toward the opposite side of the storage space). In the present specification, “upper and lower” are used for convenience of explanation, and “upper” indicates the side where the side wall 12 extends from the bottom 11 and “lower” indicates the bottom 11 side. The use state of the medical tray 10 is not limited.

  Since the medical tray 10 is made of a thin resin and has a low strength, the strength is increased by providing the flange portion 14. Although the bottom part 11 and the side wall 12 are integrally formed by vacuum forming etc. from thermoplastic resin sheets, such as polyethylene, a polypropylene, a polyvinyl chloride, for example, a material and a shaping | molding method are not limited to these. It is preferable that the flange part 14 is provided in the perimeter of the upper part of a side wall.

  The flange portion 14 is formed with a pair of projecting portions 15 projecting upward, and the pair of projecting portions 15 is formed on each of the flange portions 14 of the side wall 12 facing each other. It is preferable that the pair of protrusions 15, that is, the two protrusions 15, are arranged at the substantially central portion of each side wall 12. As shown in FIG. 6, the protrusion 15 has a concave portion 16 on the back surface. The protruding portion 15 is preferably provided on the flange portion 14 (side wall 12) located on the long side of the substantially rectangular bottom portion 11.

  As shown in FIG. 7, the height H of the protrusion 15 is preferably equal to or greater than the stacking pitch P, which is the difference in height when the medical trays 10 are stacked. The overlapping pitch P is determined by conditions such as the inclination angle of the side wall 12 of the medical tray 10 and the thickness of the flange portion 14. In this embodiment, the thickness of the flange portion 14 is determined by the overlapping pitch P. It is equal to. As shown in FIGS. 4 and 5, a step portion 21 formed locally in the form of a step that is one step lower is provided at the upper end of the flange portion 14, adjacent to the projection portion 15. Is provided with a step groove 22 (flange groove) formed by being recessed from the side (outside) to the inside (storage space side). Further, the side wall 12 is also provided with a side wall groove 23 (side wall groove portion) that is formed inwardly extending from the step portion 21 toward the bottom portion 11. The step portion 21, the step groove 22 and the side wall groove 23 constitute a bending guiding portion 20 that makes it easy to bend the side wall 12 locally.

  An undercut portion 13 is formed below the side wall 12 so as to project outward from the storage space. The undercut portion 13 has a function of preventing a long and elastic medical device such as the catheter 40 from being popped out by the elastic force when the medical device 10 is wound around and stored in the medical tray 10. .

  The bottom 11 has a first ridge that is a three-dimensionally formed line on the bottom 11 that protrudes upward and extends in a ridge to restrict the arrangement of the medical device to be stored or to give strength. 31 and a second ridge portion 32. The first ridge 31 is formed on a line L connecting the lower ends of the two side wall grooves 23 of the side wall 12. The second ridge portion 32 is not formed on the line L, but is formed so as to be divided on both sides across the line L and extend so as to intersect the line L.

  The first ridge portion 31 and the second ridge portion 32 have the bottom portion 11 bent along the line L when the side wall 12 is bent inward along the step portion 21, the step groove 22 and the side wall groove 23. The bottom bending induction part 30 which induces the bending is constructed.

  Next, the operation of the medical tray 10 according to the embodiment will be described.

  When a package product containing necessary medical instruments and medicines is provided to the medical site, and the package product is opened for diagnosis, inspection, treatment, etc., as shown in FIG. The drape 41 and the like are installed on the medical tray 10 on which are stacked. At this time, the position of the drape 41 or the like installed on the medical tray 10 is regulated by the protrusion 15 of the medical tray 10 and does not fall into the medical tray 10 but is held at an appropriate position. ing.

  Thereafter, as shown in FIG. 3, the drape 41 and the like on the medical tray 10 are taken out, and other medical instruments and the like are taken out from the medical tray 10. As shown in FIGS. 7 to 9, the two empty medical trays 10 have the protrusions 15 of the lower medical tray 10 on the side of the flange 14 of the other medical tray 10 overlaid. The two medical trays 10 are not completely overlapped with each other. In addition, the state which overlaps completely represents the state which the lower projection part 15 fitted to the recessed part 16 (refer FIG. 6) formed in the back surface of the upper projection part 15. FIG. Thereby, the side wall 12 of the upper medical tray 10 is deformed inward, and the side wall 12 of the lower medical tray 10 is deformed sideward (outward), and the side wall 12 of the upper medical tray 10 and the lower medical tray are deformed. A gap S (see FIG. 9) is formed between the ten side walls 12.

  At this time, since the height H of the protrusion 15 is equal to or greater than the overlapping pitch P (see FIG. 7), the protrusion 15 of the lower medical tray 10 is overlapped with the flange 14 of the other medical tray 10. It can be satisfactorily maintained in a state where the height is equal to or higher than that and the protrusion 15 of the lower medical tray 10 is disposed on the side of the flange portion 14 of the upper medical tray 10. In particular, when the flange portion 14 is thin, it is preferable that the protrusion 15 is long. Note that the height H is not necessarily equal to or greater than the stacking pitch P as long as the protrusion 15 of the lower medical tray 10 can be held on the side of the flange 14 of the upper medical tray 10. Also good.

  Thereafter, as shown in FIG. 10, a part of the flange portion 14 of the upper medical tray 10 is grasped and pulled upward to be separated from the lower medical tray 10. At this time, since the gap 15 is formed between the side wall 12 of the upper medical tray 10 and the side wall 12 of the lower medical tray 10 by the projecting portion 15, the upper medical tray 10 and the lower side from the gap S are formed. Since air easily flows into and out of the medical tray 10 and the surface resistance between the overlapping side walls 12 is lower than in the case of complete fitting, the stacked medical trays 10 are easily separated (removed). )be able to. In addition, the site | part which is grabbed and pulled up is not limited to the position of the arrow of FIG. 10, You may grab and pull up another site | part.

  Further, in the present embodiment, since the two protrusions 15 are provided, the air can easily flow in and the surface resistance between the side walls 12 is further reduced, so that the stacked medical trays 10 can be simplified. Can be separated. In particular, since the protrusions 15 are formed on both of the flange portions of the side wall 12 facing each other, the air is efficiently introduced from two gaps S that are relatively far apart, and the medical trays are stacked. 10 becomes easier to separate. In addition, since the two protrusions 15 are arranged at substantially the center of each of the side walls 12, the deformation and stress generated in the side walls 12 in a state where the two medical trays 10 are overlapped are dispersed as much as possible. Can be reduced.

  In addition, since the bottom portion 11 is formed to be recessed inward and has a constricted portion 17 that facilitates deformation to the inside of the side wall 12, a portion of the upper medical tray 10 is grasped and pulled upward. At this time, the side wall 12 is deformed inward while air flows in from the gap S. Thereby, since the gap S between the overlapping side walls 12 is widened, air is more likely to flow in, and the surface resistance between the side walls 12 is further reduced, so that the stacked medical trays 10 are more easily separated. It becomes possible.

  Further, the side wall 12 is provided with a bend guiding portion 20 (a step portion 21, a step groove 22 and a side wall groove 23) adjacent to the protruding portion 15 so as to easily bend the side wall 12 inward locally. When a part of the flange portion 14 of the upper medical tray 10 is grasped and pulled upward, the side wall 12 bends inward along the bending guide portion 20. In particular, since the bending guide portion 20 is provided adjacent to the protruding portion 15, air easily enters from the gap S formed by the protruding portion 15, so that the side wall 12 is easily bent inward. By such a bend, the gap S between the overlapping side walls 12 is widened, so that air is more likely to flow in and the surface resistance between the side walls 12 is further reduced, so that the stacked medical trays 10 can be made easier. Can be separated.

  In addition, since the bending guide portions 20 are provided on both of the opposing side walls 12, the bottom portion 11 is also bent along the line L between the two bending guide portions 20. As a result, the gap S becomes easier to spread, and the separation property of the stacked medical trays 10 can be further improved.

  Moreover, since the bottom bending | flexion induction | guidance | derivation part 30 formed in the bottom part 11 also induces the bending | flexion of the side wall 12 by guide | inducing the bending along the line L of the bottom part 11, separation of the piled medical tray 10 is carried out. It plays a function to make it easier.

  Therefore, according to the medical tray 10 according to the present embodiment, even if the medical tray 10 that normally has a deep and undercut portion 13 and is troublesome to separate is overlapped, the protrusion 15 and the bending guide described above are overlapped. By providing the unit 20, easy separation is possible, work efficiency is improved, and the burden on the user at the medical site can be reduced.

  When the separation of the medical tray 10 is completed, a medical instrument is installed again using the two medical trays 10, or a medical instrument that needs to be wetted is given wettability with physiological saline or the like. .

  Further, after the diagnosis, examination, treatment, or the like is completed, the medical tray 10 is discarded. However, since the concave portion 16 is formed on the back surface of the protrusion 15, the two medical trays 10 are completely removed. It can be made to fit, and the volume of waste can be reduced.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims.

  For example, the number of protrusions 15 is not necessarily two, and may be one or three or more. Further, three or more medical trays 10 can be used in an overlapping manner. Further, the bending guide portion 20 that makes it easier to locally bend the side wall 12 inward may not be in the form of a groove as in the present embodiment, for example, a cut portion cut from the upper edge of the side wall 12. Alternatively, it can be formed by a hole (for example, a slit) formed near the upper end of the side wall 12.

  Further, the step portion 21, the step groove 22 and the side wall groove 23 constituting the bending guiding portion 20 do not necessarily have to be formed. If at least one is formed, the side wall 12 can be easily bent locally inward. Function can be demonstrated.

  Moreover, although the medical tray 10 which concerns on this embodiment is resin, the protrusion part 15 of the lower medical tray 10 can be arrange | positioned to the side of the flange part 14 of the other medical tray 10 piled up upwards. Any material other than resin may be used as long as it is a flexible material.

  Moreover, the flange part 14 does not necessarily need to be formed over the perimeter.
