Description

[Technical field]

[0001] The present invention relates to a finger cot for treating tendonitis, which is used to treat tendonitis in people suffering from tendonitis in the fingers. [Background technology]

[0002] In general, in order to achieve early recovery from tendonitis occurring in the joints of the fingers, it is said that it is good to limit the range of motion of the joint where tendonitis has occurred so that the joint does not move as much as possible. One of the methods is a taping method in which tape is wrapped around the joint where tendonitis has occurred or its vicinity to limit the range of motion of the joint. JP 2022-184605 A (Patent Document 1) discloses a taping tape used in this taping method. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2022-184605 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when using the taping method, if the tape is wrapped too tightly, the veins may be compressed, causing blood circulation problems. Furthermore, if the tape is not wrapped properly, early recovery cannot be expected, so specialized knowledge of the taping method is required, and the task of wrapping the tape properly is itself troublesome.

[0005] The present invention has been made in consideration of the above-mentioned technical background, and an object of the present invention is to provide a finger cot for tendonitis that is easy to wear on the fingers and enables early recovery. [Means for solving the problem]

The finger cot for treating tendonitis as recited in any one of items 3 to 6, wherein at least one of the tip side of the connecting piece and the other end side of the peripheral wall is provided with fastening means for detachably fastening the tip side of the connecting piece to the other end side of the peripheral wall.

[0014] 8) A finger cot for tendonitis as described in any one of paragraphs 2 to 7 above, wherein the width of the reduced portion in the circumferential direction of the joint portion when the peripheral wall is placed over the joint portion is set in the range of 1 / 4 to 2 / 5 times the circumferential length of the joint portion.

[0015] 9) A finger cot for tendonitis as described in any one of paragraphs 1 to 8 above, wherein the peripheral wall has a length such that, when placed over a PIP joint as the joint where tendonitis has occurred, one end of the peripheral wall in the longitudinal direction is positioned between the DIP joint and the PIP joint, and the other end of the peripheral wall in the longitudinal direction is positioned between the PIP joint and the MP joint. Effect of the Invention

[0016] The present invention provides the following advantages.

[0017] In the above-mentioned item 1, the finger stall is put on the finger by covering the peripheral wall of the finger stall over the joint where the tendonitis has occurred, so that the finger stall can be easily put on the finger.

[0018] Furthermore, since the peripheral wall is made of elastomer and has a thickness of 3 to 7 mm, the range of motion of the joint where tendonitis has occurred can be restricted, and early recovery from tendonitis can be achieved.

[0019] In the previous section 2, since a vein called the dorsal finger vein runs along the length of the finger on the dorsal side of the finger joint, by covering the joint with a peripheral wall in a state in which at least one of the thin portion and the concave rib portion is located on the dorsal side of the joint as a reduction portion that reduces pressure on the dorsal finger vein, it is possible to reduce pressure on the dorsal finger vein caused by covering the joint with the peripheral wall, and thereby suppress the occurrence of blood circulation disorders due to pressure on the dorsal finger vein.

[0020] In the above item 3, the peripheral wall is formed with a substantially C-shaped cross section, and the space between one end and the other end of the peripheral wall in the circumferential direction is the above-mentioned concave portion, so that the peripheral wall can be easily placed over the joint portion, and the concave portion extends over the entire length of the peripheral wall, so that the pressure on the dorsal finger vein can be reliably reduced. Furthermore, by connecting the one end and the other end of the peripheral wall placed over the joint portion with the one end and the other end spaced apart by the connecting means, it is possible to prevent the peripheral wall from falling off and shifting from the joint portion while maintaining the reduced pressure on the dorsal finger vein.

[0021] In the above paragraph 4, the peripheral wall is formed by bending an elastomer blank into a cross-sectional shape that is approximately C-shaped so that one end and the other end in the width direction are separated. Therefore, when the peripheral wall (finger cot) is first placed over a joint where tendonitis has occurred, the blank is bent into a cross-sectional shape that is approximately C-shaped so that one end and the other end in the width direction are separated on the back side of the joint from the palm side of the joint, and wrapped around the joint, and the peripheral wall is placed over the joint by connecting one end and the other end in the circumferential direction of the peripheral wall (i.e., one end and the other end in the width direction of the blank) with the one end and the other end separated by a connecting means so that this bent state (i.e., wrapped state) is maintained. In this way, peripheral walls (finger cots) having an appropriate inner diameter that can achieve early recovery for joints of various thicknesses can be easily and inexpensively produced.

[0022] In the above item 5, the one end and the other end of the peripheral wall are connected by adhering an adhesive tape (connecting means) to the outer surface of the peripheral wall so as to connect one end and the other end of the peripheral wall that covers the joint portion while the one end and the other end are spaced apart. Therefore, the one end and the other end of the peripheral wall can be easily connected.

[0023] In the above paragraph 6, one end of the connecting belt (connecting means) is fastened to the other end of the connecting belt by fastening means so as to connect one end and the other end of the peripheral wall placed over the joint portion with the one end and the other end spaced apart. This makes it easy to connect one end and the other end of the peripheral wall. Furthermore, by separating the fastening of one end of the connecting belt to the other end, the connection between the one end and the other end of the peripheral wall is released, so that the peripheral wall (finger cot) can be easily removed from the joint portion.

[0024] In the above paragraph 7, the tip of the connecting piece (connecting means) is fastened to the other end side of the peripheral wall by fastening means so as to connect one end and the other end of the peripheral wall placed over the joint part in a state in which the one end and the other end are spaced apart. This makes it easy to connect the one end and the other end of the peripheral wall. Furthermore, by releasing the fastening of the tip of the connecting piece to the other end side of the peripheral wall, the connection between the one end and the other end of the peripheral wall is released, so that the peripheral wall (finger cot) can be easily removed from the joint part.

[0025] In the above paragraph 8, by setting the width of the reduced portion in the circumferential direction of the joint to a range of 1 / 4 to 2 / 5 times the circumferential length of the joint when the peripheral wall is placed over the joint, it is possible to reliably reduce pressure on the dorsal finger vein while restricting the range of motion of the joint. This makes it possible to reliably prevent blood circulation disorders caused by pressure on the dorsal finger vein.

[0026] In the above paragraph 9, the peripheral wall has a length such that one end of the peripheral wall in the length direction is located between the DIP joint part and the PIP joint part, and the other end of the peripheral wall in the length direction is located between the PIP joint part and the MP joint part, when the peripheral wall is placed over the PIP joint part as the joint part where tendonitis has occurred. This allows the bending motion of the DIP joint part and the MP joint part to be performed while restricting the range of motion of the PIP joint part where tendonitis has occurred.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] Some embodiments of the present invention will now be described with reference to the drawings.

[0029] 1 to 4 are diagrams illustrating a fingerstall 1A according to a first embodiment of the present invention.

[0030] 4, the fingerstall 1A of the first embodiment is used by covering the PIP joint J2 of the middle finger 31, which is the joint of a finger 30 that is particularly susceptible to tendonitis, with a peripheral wall 2 serving as the main body of the fingerstall 1A. The peripheral wall 2 is made of an elastomer and has flexibility and elasticity (tensile elasticity, compressive elasticity, etc.).

[0031] In the figure, the reference character "J1" denotes a DIP joint of a finger 30, the reference character "J3" denotes an MP joint, and the reference character "J4" denotes an IP joint of a thumb 32.

[0032] 1 and 2, in the finger cot 1A, a groove 7 that opens to the inside of the peripheral wall 2 is provided in a portion of the peripheral direction of the peripheral wall 2 and extends in the length direction of the peripheral wall 2. Then, as shown in Fig. 4, the peripheral wall 2 is placed over the PIP joint J2 of the middle finger 31 with tendonitis in such a manner that the groove 7 is located on the back side of the PIP joint J2 (i.e., the back side of the hand).

[0033] Here, at each joint portion of the finger 30, a vein called a dorsal finger vein (not shown) runs along the length of the finger 30 on the dorsal side, and the groove portion 7 is provided in part of the circumferential direction of the peripheral wall 2 as a reduction portion that reduces pressure on the dorsal finger vein caused by covering the PIP joint portion J2 with the peripheral wall 2.

[0034] 1 and 2, the peripheral wall 2 is formed to have a generally C-shaped cross section, and the spaced portion 23 between one end portion 3a and the other end portion 3b in the circumferential direction of the peripheral wall 2 is the above-mentioned groove portion 7. Therefore, the above-mentioned groove portion 7 extends over the entire peripheral wall 2 in the longitudinal direction.

[0035] 3, when the peripheral wall 2 is placed over the PIP joint J2 (shown by a two-dot chain line), the width H of the spaced portion 23 in the circumferential direction of the PIP joint J2 (i.e., the opening width of the groove portion 7 as the width of the reduced portion) is not limited, but is preferably set to a range of 1 / 4 to 2 / 5 times the circumferential length of the PIP joint J2 (i.e., the total circumferential length of the PIP joint J2). In this case, the pressure on the dorsal finger vein can be reliably reduced while the range of motion of the PIP joint J2 is reliably restricted.

[0036] The peripheral wall 2 is made of an elastomer as described above. Examples of the elastomer include various elastomers (thermosetting elastomers, thermoplastic elastomers) used for cushioning materials, etc. Specifically, examples of the thermosetting elastomers include natural rubber, silicone rubber, fluororubber, styrene rubber, butadiene rubber, ethylene propylene rubber, ethylene propylene diene rubber, urethane rubber, acrylic rubber, and butyl rubber, and examples of the thermoplastic elastomers include styrene-based, olefin-based, vinyl chloride-based, urethane-based, ester-based, and amide-based elastomers, and may also be hydrogenated elastomers. Furthermore, the elastomer may be in the form of an elastomer foam (including an elastomer sponge). Furthermore, the bubble form of the elastomer is not limited, and may be a closed-cell type, an open-cell type, or a solid type.

[0037] Here, since silicone rubber has high water repellency, it is preferable to use silicone rubber as the elastomer, which makes it possible to reliably limit the range of motion of the PIP joint J2, and also makes it possible to use the peripheral wall 2 for a long period of time while keeping it in a clean condition by washing the peripheral wall 2 with water when the peripheral wall 2 becomes dirty.

[0038] The peripheral wall 2 is formed by bending the above-mentioned elastomer flat base plate 20, which is approximately rectangular in plan view, into an approximately C-shaped cross section so that one end 21a and the other end 21b in the width direction W are separated from each other, as shown by the dotted line in Figure 3.

[0039] The peripheral wall 2 (base plate 20) preferably has a thickness t of 3 to 7 mm, and the thickness t of the peripheral wall 2 (base plate 20) is approximately constant over its entirety.

[0040] Furthermore, finger cot 1A is provided with connecting means 10 that connects one end 3a and the other end 3b in the circumferential direction of peripheral wall 2 having a generally C-shaped cross section that covers PIP joint portion J2 in a state in which one end 3a and the other end 3b are spaced apart, so that the bent state of base plate 20 is maintained.

[0041] In the first embodiment, the connecting means 10 includes an adhesive tape 11. More specifically, the adhesive tape 11 is a flexible single-sided adhesive tape having an adhesive surface 11a (see FIG. 3) on one side. Specifically, the adhesive tape 11 may be a commercially available vinyl tape, cloth tape, nonwoven fabric tape, or the like. The thickness of the adhesive tape 11 is not limited, and is, for example, in the range of 0.05 to 0.5 mm. The width of the adhesive tape 11 is also not limited, and is preferably in the range of 0.5 to 1 times the length of the peripheral wall 2.

[0042] Then, the adhesive tape 11 is attached to the outer surface 2a of the peripheral wall 2 in the longitudinal direction of the peripheral wall 2 so as to connect one end 3a and the other end 3b of the peripheral wall 2 in a state in which the one end 3a and the other end 3b are spaced apart from each other. L (See Figure 1) The finger cot 1A is wound around the peripheral wall 2 in the circumferential direction (i.e., the width direction W of the base plate 20) at least once so as not to protrude outward from both ends 4a, 4b of the finger cot 1A, thereby forming the finger cot 1A shown in Figures 1 and 2.

[0043] 4, the peripheral wall 2 preferably has a length such that, when the peripheral wall 2 is placed over the PIP joint portion J2, one end 4a of the peripheral wall 2 in the length direction L (see FIG. 1) is located between the DIP joint portion J1 and the PIP joint portion J2 and the other end 4b of the peripheral wall 2 in the length direction L is located between the PIP joint portion J2 and the MP joint portion J3. In this case, the DIP joint portion J1 and the MP joint portion J3 can be bent while the range of motion of the PIP joint portion J2 is limited.

[0044] According to the first embodiment of the fingerstall 1A, the fingerstall 1A is attached to the middle finger 31 by covering the PIP joint J2 of the middle finger 31 where tendonitis has occurred with the peripheral wall 2. This makes it easy to attach the fingerstall 1A to the finger 30, and does not require specialized knowledge as with the taping method.

[0045] Furthermore, peripheral wall 2 of finger cot 1A is made of elastomer and has a thickness t of 3 to 7 mm, which allows for early recovery from tendonitis. In order to allow for early recovery, a more preferable lower limit of t of peripheral wall 2 is 4 mm, a more preferable upper limit of t is 6 mm, and an even more preferable upper limit of t is 5 mm.

[0046] In the finger stall 1A of the first embodiment, when the peripheral wall 2 (finger stall 1A) is first placed over the PIP joint J2 where tendonitis has occurred, the blank plate 20 is bent in a substantially C-shaped cross section along the outer circumferential surface of the PIP joint J2 from the palm side of the PIP joint J2 so that one end 21a and the other end 21b in the width direction W of the blank plate 20 are separated on the back side of the PIP joint J2, and wrapped around the PIP joint J2, as shown in Fig. 3. In this state, the one end 21a and the other end 21b in the width direction W of the blank plate 20 become the one end 3a and the other end 3b in the circumferential direction of the peripheral wall 2.

[0047] Then, the adhesive tape 11 is wound around the outer surface 2a of the peripheral wall 2 in the circumferential direction, preferably one turn or more, so as to connect one end 3a and the other end 3b of the peripheral wall 2 in a state in which the one end 3a and the other end 3b are spaced apart. In this manner, the peripheral wall 2 is placed over the PIP joint J2, and the finger stall 1A is attached to the middle finger 31 (PIP joint J2). This makes it possible to prevent the peripheral wall 2 from falling off or shifting out of position from the PIP joint J2 while reducing pressure on the dorsal finger vein caused by placing the peripheral wall 2 over the PIP joint J2, and further makes it possible to easily and inexpensively produce the peripheral wall 2 (finger stall 1A) having an appropriate inner diameter that allows for early recovery for PIP joints J2 of various thicknesses.

[0048] With the fingerstall 1A thus produced, when going to sleep, the middle finger 31 is pulled out from within the peripheral wall 2 to remove the peripheral wall 2 from the PIP joint J2. After getting up, the middle finger 31 is inserted from the fingertip to the PIP joint J2 into the peripheral wall 2 to cover the PIP joint J2, and the fingerstall 1A is then worn on the middle finger 31.

[0049] If fingerstall 1A is damaged (for example, if adhesive tape 11 breaks or peels off), a new fingerstall is made by the method described above. If the surface of fingerstall 1A becomes dirty, a new fingerstall may be made by the method described above, or the dirt may be removed by washing with water or the like.

[0050] Fig. 5 is a diagram illustrating a fingerstall 1B according to a second embodiment of the present invention. Fig. 6 is a diagram illustrating a fingerstall 1C according to a third embodiment of the present invention. Figs. 7 and 8 are diagrams illustrating a fingerstall 1D according to a fourth embodiment of the present invention. Fig. 9 is a diagram illustrating a fingerstall 1B according to a second embodiment of the present invention. reference In these figures, elements that have the same functions as those of the fingerstall 1A of the first embodiment are given the same reference numerals. 4 Embodiment and reference form The following describes the fingerstalls 1B to 1E, focusing on the differences from the fingerstall 1A of the first embodiment.

[0051] In the second embodiment of the finger cot 1B shown in FIG. 5, the peripheral wall 2 is substantially cylindrical, and a portion of the peripheral wall 2 in the circumferential direction is not separated; that is, the peripheral wall 2 is formed continuously around the entire circumferential direction.

[0052] Furthermore, in a portion of the peripheral wall 2 in the circumferential direction, a groove 7 having a generally U-shaped cross section that opens to the inside of the peripheral wall 2 is formed extending over the entire length of the peripheral wall 2 (see FIG. 1: L) as a reduction portion that reduces pressure on the dorsal finger vein, and in the portion of the peripheral wall 2 where the groove 7 is formed, a thin portion 8 that is thinner than other portions of the peripheral wall 2 due to the formation of the groove 7 is formed extending (continuously) in the length direction of the peripheral wall 2 as a reduction portion that reduces pressure on the dorsal finger vein. Therefore, the thin portion 8 and the groove 7 as a reduction portion are formed at the same position in the circumferential direction of the peripheral wall 2, extending over the entire length of the peripheral wall 2.

[0053] In the finger cot 1B of the second embodiment, the peripheral wall 2 is placed over the PIP joint portion J2 with the thin portion 8 and the grooved rib portion 7 located on the back side of the PIP joint portion J2. Here, by forming the grooved rib portion 7 in a portion of the peripheral wall 2 in the circumferential direction, the elastic force (tensile elastic force, compressive elastic force, etc.) of the thin portion 8 of the peripheral wall 2 is lower than that of other portions of the peripheral wall 2. Therefore, since not only the grooved rib portion 7 but also the thin portion 8 are located on the back side of the PIP joint portion J2, it is possible to reliably reduce pressure on the back finger vein caused by placing the peripheral wall 2 over the PIP joint portion J2.

[0054] When the peripheral wall 2 is placed over the PIP joint J2, the opening width H of the groove 7 and the width H of the thin portion 8 as the width of the reduced portion in the circumferential direction of the PIP joint J2 are preferably set to 1 / 4 to 2 / 5 times the circumferential length of the PIP joint J2, as in the first embodiment. The depth f of the groove 7 is not limited, and is preferably 1 mm or more, more preferably 2 mm or more, and further preferably 3 mm or more. The upper limit of f is not limited, and may be less than the thickness t of the peripheral wall 2.

[0055] In the second embodiment described above, both the thin portion 8 and the grooved rib portion 7 are provided as a reduction portion in a portion of the circumferential direction of the peripheral wall 2; however, the present invention is not limited to this, and, for example, of the thin portion 8 and the grooved rib portion 7, only the thin portion 8 may be provided as the reduction portion, or only the grooved rib portion 7 may be provided.

[0056] In the finger cot 1C of the third embodiment shown in Fig. 6, the connecting means 10 includes a connecting belt 13. The connecting belt 13 is flexible and is made of, for example, flexible synthetic resin (polyester, nylon, polyurethane, etc.) or cloth. The connecting belt 13 is wound around the outer surface 2a of the peripheral wall 2 that covers the PIP joint portion J2, one or more times in the circumferential direction so as to connect one end 3a and the other end 3b of the peripheral wall 2 with the one end 3a and the other end 3b spaced apart from each other. The connecting belt 13 may be made of a material having elasticity such as tensile elasticity or compressive elasticity.

[0057] The thickness of the connecting belt 13 is not limited, and is, for example, in the range of 0.1 to 2 mm. The width of the connecting belt 13 is also not limited, and is preferably in the range of 0.5 to 1 times the length of the peripheral wall 2. The number of connecting belts 13 may be more than one, such as two, and in this case, these connecting belts 13 are wound approximately parallel to each other on the outer surface 2a of the peripheral wall 2, for example, spaced apart in the longitudinal direction L of the peripheral wall 2.

[0058] At least one of the longitudinal ends 13a and 13b of the connecting belt 13 is provided with a fastening means 14 for detachably fastening the one end 13a of the connecting belt 13 to the other end 13b of the connecting belt 13 while the connecting belt 13 is wound around the outer surface 2a of the peripheral wall 2 covering the PIP joint portion J2.

[0059] This 3 In the embodiment, the fastening means 14 includes a pair of hook-and-loop fasteners 15a, 15b that are separably engaged with each other. In the pair of hook-and-loop fasteners 15a, 15b, one hook-and-loop fastener 15a is fixed to the inner surface of one end 13a of the connecting belt 13 by sewing, adhesive, or the like, and the other hook-and-loop fastener 15b is fixed to the outer surface of the other end 13b of the connecting belt 13 by sewing, adhesive, or the like.

[0060] In the finger cot 1C of the third embodiment, the peripheral wall 2 is placed over the PIP joint J2 in such a state that the separation portion 23 (recessed portion 7) between the one end 3a and the other end 3b in the peripheral direction of the peripheral wall 2 is located on the back side of the PIP joint J2. In this state, the connecting belt 13 is wound around the outer surface 2a of the peripheral wall 2 in the peripheral direction by one or more turns (one turn in the figure) so as not to protrude outward from both ends (see FIG. 1: 4a, 4b) in the length direction L of the peripheral wall 2, and the hook-and-loop fastener 15a on the one end 13a side of the connecting belt 13 is separably engaged with the hook-and-loop fastener 15b on the other end 13b side of the connecting belt 13 in an overlapping manner. As a result, the one end 3a and the other end 3b of the peripheral wall 2 are connected by the connecting belt 13 so as to connect the one end 3a and the other end 3b in a separated state. This makes it possible to easily connect the one end 3a and the other end 3b of the peripheral wall 2.

[0061] In addition, by shifting the position at which the hook-and-loop fastener 15a on one end 13a of the connecting belt 13 engages with the hook-and-loop fastener 15b on the other end 13b in the longitudinal direction of the connecting belt 13, the restraining force exerted by the peripheral wall 2 on the PIP joint portion J2 can be adjusted.

[0062] When removing the peripheral wall 2 (finger stall 1C) from the PIP joint J2, the peripheral wall 2 may be removed by pulling out the middle finger 31 from within the peripheral wall 2, or the one end 13a side of the connecting belt 13 may be pulled in a peeling direction toward the other end 13b side to release the engagement between the hook-and-loop fastener 15a on the one end 13a side and the hook-and-loop fastener 15b on the other end 13b side, separating the one end 13a side of the connecting belt 13 from the other end 13b side, thereby releasing the connection between the one end 3a and the other end 3b of the peripheral wall 2, and then removing the peripheral wall 2 from the PIP joint J2. This allows the peripheral wall 2 (finger stall 1C) to be easily removed from the PIP joint J2.

[0063] In the finger cot 1C, the peripheral wall 2 may be formed, as in the first embodiment described above, by bending a flat elastomer base plate 20 into an approximately C-shaped cross section so that one end 21a and the other end 21b in the width direction W are spaced apart on the back side of the PIP joint portion J2.

[0064] In the finger cot 1D of the fourth embodiment shown in Figs. 7 and 8, the connecting means 10 includes a plurality of connecting pieces 17 extending from one end 3a of the peripheral wall 2. More specifically, the number of connecting pieces 17 is two, and these connecting pieces 17 are integrally provided at one end 3a of the peripheral wall 2 at a distance from each other in the length direction L of the peripheral wall 2. The connecting pieces 17 are flexible and are made of, for example, a flexible synthetic resin (polyester, nylon, polyurethane, etc.). The connecting pieces 17 may have elasticity such as tensile elasticity or compressive elasticity. The width of each connecting piece 17 is not limited, and is, for example, in the range of 0.1 to 0.3 times the length of the peripheral wall 2.

[0065] At least one of the tip 17a side of the connecting piece 17 and the other end 3b side of the peripheral wall 2 is provided with a fastening means 18 for detachably fastening the tip 17a side of the connecting piece 17 to the other end 3b side of the peripheral wall 2.

[0066] In this fourth embodiment, the fastening means 18 includes an engaging portion 19a provided on the tip portion 17a side of the connecting piece 17, and a locking portion 19b provided on the other end portion 3b side of the peripheral wall 2 and which is capable of being engaged with and releasably engaged with the engaging portion 19a.

[0067] Specifically, the locked portions 19a are locking holes, and the locking portions 19b are locking protrusions. Each connecting piece 17 has a plurality of locking holes (locking portions) 19a (three in detail), and these locking holes 19a are arranged at intervals on the tip end 17a side of the connecting piece 17 in the extension direction of the connecting piece 17. The number of locking protrusions (locking portions) 19b is the same as the number of connecting pieces 17. The locking protrusions 19b have rigidity and are made of, for example, hard plastic, and are provided on the other end 3b side of the peripheral wall 2 in a fixed state protruding from its outer surface 2a.

[0068] In the finger cot 1D of the fourth embodiment, the peripheral wall 2 is placed over the PIP joint J2 in a state where the separation portion 23 (recessed portion 7) between one end 3a and the other end 3b in the circumferential direction of the peripheral wall 2 is located on the back side of the PIP joint J2 (see FIG. 8). In this state, the locking projections 19b corresponding to the locking holes 19a of the connecting pieces 17 are inserted and locked. As a result, the one end 3a and the other end 3b of the peripheral wall 2 are connected by the connecting pieces 17 in a state where the one end 3a and the other end 3b are separated from each other. This makes it easy to connect the one end 3a and the other end 3b of the peripheral wall 2.

[0069] Here, since a plurality of locking holes 19a are arranged at intervals in the extension direction of the connecting piece 17 on the tip end 17a side of the connecting piece 17, the restraining force applied to the PIP joint portion J2 by ​​the peripheral wall 2 can be adjusted by selecting from among these locking holes 19a the locking hole 19a into which the locking protrusion 19b is inserted.

[0070] In addition, when the peripheral wall 2 is placed over the PIP joint portion J2, the back side of the PIP joint portion J2 is located between both connecting pieces 17, 17 at the separation portion 23 (recessed portion 7) between one end 3a and the other end 3b of the peripheral wall 2.

[0071] When removing the peripheral wall 2 (finger stall 1D) from the PIP joint J2, the peripheral wall 2 may be removed by pulling out the middle finger 31 from within the peripheral wall 2, or the peripheral wall 2 may be removed by removing the locking projection 19b from the locking hole 19a of the connecting piece 17 to release the locking of the locking projection 19b with the locking hole 19a, thereby separating the tip end 17a side of the connecting piece 17 from the other end 3b side of the peripheral wall 2, thereby releasing the connection between the one end 3a and the other end 3b of the peripheral wall 2, and then removing the peripheral wall 2 from the PIP joint J2. This makes it easy to remove the peripheral wall 2 (finger stall 1D) from the PIP joint J2.

[0072] In the fourth embodiment, the fastening means 18 includes the locking hole 19a and the locking projection 19b, but in the present invention, the fastening means 18 may include a pair of hook-and-loop fasteners 15a, 15b that are separably locked to each other, like the fastening means (14) of the finger cot 1C in the third embodiment. In this case, it is preferable that, in the pair of hook-and-loop fasteners 15a, 15b, one hook-and-loop fastener 15a is provided on the tip end 17a side of the connecting piece 17 (more specifically, on the inner surface of the tip end 17a side), and the other hook-and-loop fastener 15b is provided on the other end 3b side of the peripheral wall 2 (more specifically, on the outer surface of the other end 3b side).

[0073] In the finger cot 1D, the peripheral wall 2 may be formed, as in the first embodiment described above, by bending a flat elastomer base plate 20 into an approximately C-shaped cross section so that one end 21a and the other end 21b in the width direction W are spaced apart on the back side of the PIP joint portion J2.

[0074] As shown in Figure 9 referenceIn the finger cot 1E having the above-mentioned configuration, the peripheral wall 2 is generally cylindrical and is formed continuously around the entire circumference. Furthermore, the peripheral wall 2 does not have any reducing portion such as the thin portion 8 or the grooved portion 7 (spaced portion 23) that would reduce pressure on the dorsal finger vein, and the thickness t of the peripheral wall 2 is generally constant around the entire circumference.

[0075] In this fingerstall 1E, the middle finger 31 is inserted from the fingertip to the PIP joint J2 into the peripheral wall 2, whereby the peripheral wall 2 covers the PIP joint J2 and the fingerstall 1E is worn on the middle finger 31. On the other hand, by pulling the middle finger 31 out from within the peripheral wall 2, the peripheral wall 2 is removed from the PIP joint J2.

[0076] In the finger cot 1E, the peripheral wall 2 may be formed by bending a flat elastomer blank 20 into a substantially cylindrical shape and adhering one end (more specifically, one end face) and the other end (more specifically, the other end face) with an adhesive, etc. In the figure, an adhesive part 25 between one end (one end face) and the other end (the other end face) of the blank 20 in this case is shown by a dashed dotted line, and at this adhesive part 25, one end and the other end of the blank 20 are adhered in a butt-to-butt manner.

[0077] Although several embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention.

[0078] For example, in the above-mentioned embodiment, the finger sacks 1A to 1E are used by covering the peripheral wall 2 over the PIP joint J2 of the middle finger 31, which is a joint of the joints of the fingers 30 that is particularly susceptible to tendonitis, but in the present invention, the finger sack may also be used by covering, for example, the IP joint J4 of the thumb 32, which is another joint of the joints of the fingers 30 that is particularly susceptible to tendonitis. In this case, it is preferable that the peripheral wall 2 has a length such that, when covered over the IP joint J4, one end 4a of the peripheral wall 2 in the length direction L is located between the tip of the thumb 32 and the IP joint J4, and the other end 4b of the peripheral wall 2 in the length direction L is located between the IP joint J2 and the MP joint J3 of the thumb 32.
