Description

  The present invention enables a person who cares for a bedridden patient at home, facility, hospital, etc. to move, change the direction of the patient on the bed when changing the patient's clothes or changing sheets, mattresses, etc. The present invention relates to a transfer sheet used for moving a patient from a bed or the like to a stretcher, from a stretcher to an operating table, an examination table, or the like or vice versa for examination.

  Traditionally, patients who are bedridden in their homes, facilities, hospitals, etc. change their clothes and sheets, change their position to prevent pressure ulcers, move to a bed or stretcher for examination and treatment, etc. The patient was moved by holding, dragging, and lifting.

  Such movement of the patient requires a considerable amount of force. In particular, when a heavy patient is lifted, a plurality of hands are required.

  Also, in recent years, caregivers who care for elderly people who are bedridden at home are often elderly people or helper people are weak women, and it is difficult to collect human resources and it is difficult to do it alone. It must not be. Therefore, moving the patient places a great burden on the caregiver's body.

  In addition, the patient's side may be moved with an unreasonable posture or may be partially pulled, and the movement is also painful.

    Under such circumstances, transfer sheets using various woven or knitted fabrics and films have been put on the market as a moving aid that eases the burden and pain of caregivers and patients and facilitates movement of patients.

In the open patent gazette, a moving sheet intended to move a patient is proposed. For example, smooth fabric and corrugated fabric, or separate corrugated fabrics with different wrinkling directions are overlapped and slid together to reduce frictional resistance between opposing sheet surfaces and facilitate patient movement and rotation (Refer to patent document 1), the smooth sheet and the concavo-convex sheet are overlapped and slipped together to reduce the frictional resistance between the opposing sheet surfaces (refer to patent document 2), and a thin film such as polyethylene is stacked A thing (refer patent document 3) etc. are proposed.

  However, the moving sheets obtained by superimposing sheets having different surface shapes or cross-sectional shapes in Patent Documents 1 and 2 may be caught by different surface shapes or cross-sectional shapes depending on the direction in which the sheets are slid or superimposed. On the contrary, there was a problem that the slipperiness deteriorated. Further, when folded and carried, there is a problem that the sheet surfaces do not mesh with each other because the surface shape or cross-sectional shape of the sheets is different, and the gap between the sheet surfaces becomes large and bulky, making it difficult to store and carry.

  Furthermore, the transfer sheet with the film of Patent Document 3 has water permeability in addition to the problem that it is likely to be wrinkled and slippery easily when used for the movement of a bedridden patient over a long period of time. There was a problem of poor washability.

  Thus, although all of the conventional moving sheets are easy to operate, they have not been able to satisfy sufficient performance in terms of slipperiness, portability, and moving distance.

  Therefore, the object of the present invention is to improve the shortcomings of the prior art, can be used easily at home and in hospitals, improve the slipperiness in all directions more than ever, and has excellent movement distance and portability. It is to provide a sheet for use.

  In order to achieve the above object, the transfer sheet of the present invention has the following configuration.

  That is, one aspect of the transfer sheet of the present invention is a plain fabric in which the sheet body is formed of a cylindrical or overlapping sheet-like member, and the sheet-like member is composed of long fiber yarns having a fineness of 81 dtex or less. In addition, the inter-fiber coverage is 3000 or more. This moving sheet preferably has two or more sets of opposing sheet surfaces. More preferably, the ground lines of the opposing sheet surfaces intersect at an angle of 15 degrees to 75 degrees. More preferably, the thickness of the sheet-like member is 0.16 mm or less.

  With the transfer sheet of the present invention, a person who cares for a bedridden patient at home or in a hospital can move the patient with little effort and is easy to carry and can be easily used at home or in a hospital. A transfer sheet can be obtained.

  Hereinafter, the transfer sheet of the present invention will be described in detail with reference to one embodiment shown in the drawings.

  FIG. 1 is a perspective view showing an embodiment of the transfer sheet of the present invention, and FIG. 2 is a perspective view showing an example of another embodiment of the transfer sheet of the present invention. FIG. 3 is a perspective view showing an example of still another aspect of the moving sheet of the present invention. FIG. 4 is an enlarged view of the sheet-like member 2 of the moving sheet shown in FIGS. 1, 2, and 3. FIG. 5 is a top view of the sheet body 1 of the moving sheet shown in FIG. 6 is a development view of the sheet body 1 of the moving sheet shown in FIG.

The movement sheet of the present invention reduces the burden on the patient's own human body due to frictional resistance generated between the patient and the bed when the patient is moved, and the caregiver's labor. Place between. Since it is necessary to form opposing sheet surfaces for bringing the sheet-like members of the moving sheet into contact with each other and sliding them, the sheet-like members are overlapped or a cylindrical structure. For this purpose, for example, as shown in FIG. 1, a structure in which a sheet main body 1 configured by overlapping sheet-like members 2 is joined by a joining portion 5, or an integral sheet-like member 2 as shown in FIG. It has a structure in which a sheet main body 1 configured to be folded in a letter shape is joined by a joining portion 5, and a structure in which an integral sheet-like member 2 is formed in a cylindrical shape as shown in FIG. Here, when joining the joint part 5 in the sheet body 1, joining methods such as sewing using a sewing thread, joining using an adhesive tape, welding using a high-frequency welder or an ultrasonic sewing machine, etc. The method may be any method commonly used.
Moreover, the aspect in which the junction part 5 was concealed inside by folding etc. is preferable. When the seat body 1 is slid by hiding the joint portion 5 inside, when the movement by the caterpillar mechanism, that is, the rotational motion is performed, there is no catch between the joint portion 5 and the bed or the human body because the seat outside is flat, Easy to rotate.

  In addition, the sheet surface which opposes in this invention means each contact surface of the sheet-like members 2, Specifically, the point of the code | symbol 3 in FIGS. 1-3 is pointed out.

  As an element constituting the transfer sheet of the present invention, a material of the sheet-like member 2 constituting the sheet body 1 is made of a long fiber yarn having a fineness of 81 dtex or less, and a woven fabric having an interfiber coverage of 3000 or more is used. is there.

In the present invention, the inter-fiber coverage is the ratio of the yarn width of the fibers constituting the plain woven fabric to the gap between the fibers as shown in FIG. The sum of the product of the number of warps 6 per inch and the product of the square root of the yarn width 9 of the wefts 7 and the number of wefts 7 per inch. The unit of the yarn width in the present invention is μm. The inter-fiber coverage (K) is obtained by the following calculation formula (1) ( Equation 1).

シート状部材２の素材に用いる平織物の繊維間カバー率としては，３０００以上であることが滑り性が良く好適である。シート状部材２に用いる平織物の繊維間カバー率が３０００未満であると、平織物を構成する経糸６と緯糸７間の隙間１０が広く、シート状部材２の滑り方向におけるせん断強力が低下し、シート状部材２を重ね合わせて滑らせる際、シート状部材２の滑り方向においてせん断変形が生じ滑り性が悪くなる。より好適には３０００〜３５００の範囲である。また経糸および緯糸の断面は特に限定されないが、楕円形状であることが糸幅が大きく繊維間カバー率大となり、より好ましい。

The covering ratio between fibers of a plain woven fabric used as the material for the sheet-like member 2 is preferably 3000 or more because of good slipperiness. When the cover ratio between the fibers of the plain fabric used for the sheet-like member 2 is less than 3000, the gap 10 between the warp 6 and the weft 7 constituting the plain fabric is wide, and the shear strength in the sliding direction of the sheet-like member 2 is reduced. When the sheet-like member 2 is slid and overlapped, shear deformation occurs in the sliding direction of the sheet-like member 2 and the slipperiness is deteriorated. More preferably, it is in the range of 3000-3500. The cross sections of the warp and weft are not particularly limited, but an elliptical shape is more preferable because the yarn width is large and the inter-fiber coverage is large.

  As the fiber of the plain woven fabric used for the material of the sheet-like member 2, a long fiber is preferable because it has a tensile strength that can withstand long-term use, has a smooth surface, and has good slipperiness in all directions. When a film is used as the material for the sheet-like member 2, the tensile strength is low and it is broken during use. When short fibers are used as the plain woven fibers of the sheet-like member 2, when the sheet-like members 2 are overlapped and slid, the surface of the short fibers constituting the woven fabric is caught by the fluffs on the opposing sheet surface 3. , Slipperiness becomes worse.

  The fineness of the fibers of the plain woven fabric used as the material for the sheet-like member 2 is preferably 81 dtex or less because of good slipperiness. If the fineness of the fiber used for the material of the sheet-like member 2 is 82 dtex or more, there is a large step difference due to the height difference between the warp yarn 6 and the weft yarn 7 that intersect each other and constitute the plain fabric, and the sheet-like member 2 is overlapped. At the time of sliding, a step difference due to the height difference between the warp 6 and the weft 7 intersecting each other is caught on the opposing sheet surface 3, and the slipperiness is deteriorated. More preferably, it is in the range of 20 dtex to 40 dtex.

  Moreover, as a suitable structure structure of the sheet-like member 2 in this invention, as shown in FIG. 4, the woven structure of the fabric used for the sheet-like member 2 consists of a plain fabric. When the woven structure of the woven fabric used for the sheet-like member 2 is a twill woven fabric or a satin woven fabric, when the sheet-like member 2 is overlapped and slid, it opposes depending on the direction in which the sheet-like member 2 is overlapped or slid. In the sheet surface 3, the fabric surface is caught by wrinkles, and the slipperiness is deteriorated.

  In the present invention, the smoothness of the surface of the sheet-like member 2 and the increase in tensile strength can improve the slipperiness on the opposite sheet surface 3 of the cylindrical or superimposed sheet-like member 2.

  Further, as another element constituting the moving seat of the present invention, as shown in FIGS. 1, 2, and 6, in the mechanism of the seat body 1, two or more sets of opposing sheet surfaces of the sheet-like member 2 are provided and slipped. It is preferable to use a mechanism for matching. In the example of FIGS. 1 and 6, three sheet-like members 2 are overlapped, and in the overlapped sheet-like member 2, the number of sets of opposing sheet surfaces 3 is the first sheet-like member 2 a-the second sheet-like member. A total of two sets are provided between 2b and between the second sheet-like member 2b and the third sheet-like member 2c.

  The sheet for movement according to the present invention increases the number of pairs of opposing sheet surfaces 3 in the stacked sheet-like member 2, thereby increasing the relative movement distance by sliding between the opposing sheet surfaces 3. The moving distance can be further increased. In the mechanism of the sheet main body 1, any number of pairs of sheet surfaces facing each other may be used. More preferably, the range of 2 to 4 sets is not bulky, and the movement distance and portability of the sheet body 1 are both good and more preferable.

  In the present invention, by using a mechanism in which two or more sets of opposite sheet surfaces of the sheet-like member 2 are provided, the relative movement distance by sliding between the opposite sheet surfaces 3 in the stacked sheet-like members 2 is increased. Thus, it becomes possible to satisfy the moving distance of the sheet body 1 more.

  In addition, as a method of configuring the opposing sheet surfaces 3, a method of stacking a plurality of sheet-like members 2 in FIG. 1, a method of folding one sheet-like member 2 in FIG. 2, and a cylindrical sheet in FIG. Although there is a method of using the shaped member 2, etc., it is of course possible to combine them. For example, if two cylindrical sheet-like members 2 are stacked and joined, the sheet main body 1 having three pairs of opposing sheet surfaces 3 can be produced.

  Moreover, the aspect by which 2 directions are open | released, ie, the aspect by which 2 directions were joined as FIG. When the four directions or the three directions are joined, the motion by the caterpillar mechanism, that is, the rotational motion cannot be performed, and the relative movement distance by the sliding of the seat surface 3 is small, and it is difficult to obtain a satisfactory effect. In addition, in a mode in which three directions or four directions are open, that is, a mode in which only one direction is joined or a mode in which there is no joined portion, the degree of freedom is large and the movement range is wide, but it is difficult to collect and is easy to store and portable. This is a little inferior.

  Furthermore, as another element constituting the moving sheet of the present invention, as shown in FIGS. 5 and 6, in the sheet-like member 2 which is cylindrical or overlapped, the ground line of the opposing sheet surface 3 has a ground line of 15 It is preferable to cross at an angle of 75 degrees.

  As shown in FIG. 4, the ground line here refers to the axial directions of the warp 6 and the weft 7 constituting the sheet-like member 2. The ground line 11 of the warp 6 and the ground of the weft 7 are the same. The line of sight 12 is formed.

  The crossing angle 13 of the line of sight on the opposite sheet surface 3 is preferably 15 to 75 degrees because the slipperiness is good. When it is 15 degrees or less, when sliding the sheet surfaces 3 facing each other, the warps 6 or the wefts 7 are caught, and the slipperiness is not improved. On the other hand, when the angle is 75 degrees or more, the warp 6 and the weft 7 are caught when the opposing sheet surfaces 3 are slid together, and the slipperiness is not improved. A range of 35 to 55 degrees is more preferable.

  In the example of FIGS. 5 and 6, three sheet-like members 2 are overlapped, and in the overlapped sheet-like member 2, the ground lines 11 of the warps 6 and the ground lines 12 of the weft threads 7 are opposed to each other on the sheet surface 3. Of the warp 6 of the first sheet-like member 2a and the ground line 11b of the warp 6 of the second sheet-like member 2b, and the warp 6 of the second sheet-like member 2b. Between the ground line 11b and the ground line 11c of the warp 6 of the third sheet-like member 2c, and between the ground line 12a of the weft 7 of the first sheet-like member 2a and the weft 7 of the second sheet-like member 2b The crossing angle 13 between the ground lines 12b between the ground line 12b and the ground line 12b of the weft 7 of the second sheet-like member 2b and the ground line 12c of the weft 7 of the third sheet-like member 2c is 45 degrees. And constituting the seat body 1 A.

  In the present invention, in the cylindrical or superposed sheet-like member 2, the ground lines of the warp 6 and the weft 7 of the opposite sheet surface 3 cross each other and slide together to satisfy higher slipperiness. It becomes possible.

  Furthermore, as a preferable aspect of the transfer sheet of the present invention, it is preferable that the thickness 4 of the sheet-like member 2 is 0.16 mm or less because of good portability.

  When the thickness 4 of the sheet-like member 2 is 0.17 mm or more, the folded sheet main body 1 is bulky and is not portable when folded and stored. A range of 0.05 to 0.12 mm is more preferable.

In order to further improve portability, the transfer seat of the present invention may be provided with a pocket 14 for housing the seat body 1 integrally with the seat body 1 as shown in FIG. . At that time, if the thickness 4 of the sheet-like member 2 is 0.17 mm or more, the sheet main body 1 is too thick and difficult to be accommodated. Therefore, it is necessary to provide a small gap, that is, a gusset in the pocket. to but requires labor, when the thickness 4 of the sheet-like member 2 is less than 0.16 mm, it is easy to the accommodating sheet body 1 without providing a gusset pocket, which is preferable.

  In the present invention, it is possible to improve the portability of the sheet body 1 by reducing the thickness 4 of the sheet-like member 2.

  The sheet-like member 2 constituting the sheet body 1 in the present invention is coated with a deodorant or antibacterial agent for imparting deodorant or antibacterial properties, or coated with urethane or acrylic for imparting waterproofness. In addition, the surface of the sheet-like member 2 located outside the sheet body 1 that is in contact with the human body, that is, the sheet surface of the sheet-like member 2 is laminated with an anti-slip agent coating or a film that prevents the human body from slipping. It may be provided, or may be provided with a quilted fabric into which a towel or padding for imparting sweat absorbency is inserted. Furthermore, it is possible to add a fluorine-based or silicon-based finish on the opposing sheet surface 3 of the cylindrical or superimposed sheet-like member 2 in order to further improve the slipperiness.

  The fiber that is the material of the sheet-like member 2 in the present invention may be any of natural fiber, chemical fiber, and synthetic fiber, and more preferably, filament yarns such as polyamide and polyester are more preferable because of excellent slipperiness and wear resistance. . In particular, when a fluorine fiber is used, it is possible to form a transfer sheet having high slipperiness and superior slipperiness, which is more preferable.

  The moving sheet according to the present invention can be used not only for a cared person but also for a healthy person. Can be facilitated. That is, it can be widely used not only as a nursing tool but also as a moving sheet.

The transfer sheet of the present invention has a higher evaluation score, that is, the smaller the friction coefficient, the better the slipperiness. An evaluation score of 4 points or more, that is, a range having a friction coefficient of less than 2.5 was considered effective. The evaluation criteria are shown in Table 1.

(2) Evaluation of moving distance The moving distance when a person (patient role, weight of about 60 kg) is actually laid on the moving sheet and moved in a straight line in the left-right direction (lateral direction as viewed from the patient role) as the moving direction. The actual size was measured using a metal scale and evaluated in five stages. The moving sheet of the present invention is superior in moving distance as the evaluation score is higher. A range of 3 or more evaluation points, that is, a moving distance of 40 cm or more was considered effective. The evaluation criteria are shown in Table 1.

(3) Portability evaluation The thickness when an 80 cm × 75 cm transfer sheet was folded into 16 folds was measured and evaluated in five stages. The thickness was measured by using a JIS L 1096 ordinary method and measuring the thickness when a pressure of 23.5 kpa was applied. The transfer sheet of the present invention has a higher evaluation score, that is, the smaller the thickness when folded, the better the portability. An evaluation score of 4 points or more, that is, a range of less than 6 mm in thickness when folded was considered effective. The evaluation criteria are shown in Table 1.
