2. Description of the Related Art Generally, when treating a toe or a broken finger or other injury requiring suturing, it is required that the joint bend is suppressed, that is, the joint is fixed so as not to move. In the treatment of finger or finger fractures, a method of fixing the affected area with a cast is also used.However, this cast is troublesome because it is necessary to wait for the gypsum to harden at the time of wearing. It is not suitable for immersion in water at work and is not easy to remove. Further, there is a disadvantage that it is difficult to reuse the cast once the gypsum has hardened.

Therefore, conventionally, a finger fixing device as shown in FIG. 7 has been used. This finger fixing device 25 is shown in FIG.
As shown in FIG. 5, a tip portion of a metal plate 26 is bent to form an inclined portion 27, and a sponge 28 is attached as a cushioning material on the upper surface side on which a finger is placed, and furthermore, a pair of bands 29 for fixing to a finger. , 29a are provided at two locations. A member (for example, a Velcro tape) for fastening the two to the tip portions of the bands 29, 29a
Is provided.

[0004] When the user wears the finger, it is necessary to use a finger as shown in FIG.
As shown in the figure, the finger 30 including the joint 30b is placed on the sponge 28 with the fingertip 30a pressed against the inclined portion 27, and the bands 29, 29a are wound around the finger 30 so that the two are fastened. I have. As a result, the bending motion of the joint 30b is suppressed by the plate 26, and for example, the finger 3 for treating a fracture or a fingertip of the joint 30b portion.
Fixation of 0 is ensured. In addition, the finger fixing device 25 can be used even after being removed, and can be reused.

[0005]

However, since the finger fixing device 25 shown in FIG. 7 places the finger 30 on the metal plate 26 and winds and fixes the belts 29 and 29a, the finger fixing device 25 shown in FIG. In addition to the trouble of wearing, the feeling of wearing varies depending on the degree of winding of the belts 29 and 29a, and there is a problem that the user may feel uncomfortable when the belt is once removed and then worn again. In addition, the finger fixing device 25 has a sponge 28 attached as a cushioning material on the plate 26 in order to improve the feeling of wearing. However, the sponge 28 contains water during bathing or water work, and Not only does it worsen the water, but also because the water is difficult to dry,

In order to solve the above-mentioned problems, the invention according to claim 1 suppresses a bending operation of a joint by fitting a finger while covering a bending side of at least one or more joints. And a tubular finger fixing device formed of a material having elasticity, wherein a notch portion is formed along a longitudinal direction thereof, and a contact portion for contacting a fingertip so as to extend a joint is provided. Is adopted. In this finger fixing device, a notch is formed in the longitudinal direction,
An elastic force acts in a direction in which the cutout portion is widened, and the state where the finger is inserted is maintained by using the elastic force, and the contact portion suppresses the bending operation of the finger. In addition, since this elastic force gives a buffering action to the finger, a cushioning material such as a sponge is not required, so that the deterioration of the feeling of wearing when wet with water is reduced and the durability is improved.

The invention according to claim 2 is based on the finger fixing device according to claim 1, wherein a technology is provided in which a hole for ventilation is provided on a peripheral surface. In this finger fixing device, since the inside and the outside of the finger fixing device are communicated with each other through the hole portion, the hole portion serves as a vent hole, thereby acting as a drainer when the inside is stuffy or immersed in water. According to a third aspect of the present invention, in the finger fixing device of the first or second aspect, a technique is employed in which at least a part is formed of a transparent or translucent material. In this finger fixing device, at least a part (including the whole) is formed of transparent or translucent, so that it is easy to observe the affected part, and it is easy to confirm the degree of contamination by clearing the dirt of the finger fixing device itself. Become.

According to a fourth aspect of the present invention, in the finger fixing device of the first, second, or third aspect, a technique of chamfering an edge portion of the peripheral surface that contacts the finger is applied. In this finger fixing device, chamfering is performed on an edge portion that hits a finger, so that contact with the skin can be softened. In particular, by chamfering the edge portion on the inner surface side, it is possible to further improve the feeling of wearing. It becomes possible.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. 1A and 1B show a finger fixing device according to the present invention, wherein FIG. 1A is a perspective view, and FIG. 1B is a cross-sectional view taken along line AA of FIG. This finger fixing device 1 is shown in FIG.
As shown in (a), a main body 2 is formed in a tubular shape with a predetermined inner diameter from transparent acrylic, and a cutout 3 is formed along a longitudinal direction thereof, and an extension 4 is provided on a base end side. The contact portion 5 is provided on the distal end side. In addition,
The cutouts 3 are formed with a length L1 along the longitudinal direction of the main body 2, and the intervals are arbitrary.

Further, the main body 2 is provided with a plurality of holes 6 communicating between the inside and the outside of the main body 2. Whether or not to form the holes 6 and the position and number of the holes 6 are arbitrary. For example, a number of holes 6 may be arranged at places where there are many sweat glands of the finger on which the finger is worn, so as to take measures against sweat. The edge portion 2a corresponding to the finger of the main body 2 is chamfered to improve the contact with the finger, but whether or not the chamfer is performed is optional.

Further, the main body 2 is not limited to the acrylic material, but may be formed of an elastic material such as another synthetic resin or metal. Whether or not is optional. Further, other than making the whole main body 2 transparent, only a part of the main body 2 may be made transparent. As described above, since the main body 2 is formed of an elastic material, as shown in FIG. 1B, the main body 2 is elastically deformed in a direction in which the notch 3 is expanded. Therefore, by setting the inner diameter of the main body 2 to such an extent that the notch 3 is widened when the finger is fitted, the finger fixing tool 1 is held by the finger.

In particular, in the treatment of fractures and fingertips, the affected part is swollen at the beginning of treatment, but the swelling grows as healing occurs. Therefore, it is considered that the outer diameter of the finger to be worn decreases with time. By using the elastic deformation of the main body 2 having the notch 3 like the fixing tool 1 to hold the main body 2 on the finger, a change in the outer diameter of the finger is allowed by the elastic deformation of the main body 2 and the wearing state is achieved. Can be maintained for a long time. However, since the outer diameter of the finger varies depending on the individual and the like, it is preferable to prepare several types of finger fixing devices 1 having different inner diameters. The elastic force of the main body 2 can also be adjusted by changing the arrangement and the number of the holes 6.

The extension portion 4 is formed by extending the main body portion 2 on the side opposite to the notch portion 3, which is not only the first joint 7 b of the finger 7 but also the second joint 7, as shown in FIG. Joint 7c
Can be also covered. This is effective when it is desired to suppress the bending operation of the second joint 7c in accordance with the position of the affected part, and when treating the finger, it is better to suppress the bending operation of both the first joint 7b and the second joint 7c. For good reason, the bent side of the second joint 7c is also covered. However, the present invention is not limited to this, and may be a type in which the extension 4 is shortened and the bending side of the second joint 7c is not covered.

As shown in FIG. 2, the contact portion 5 is
Is provided in a state of being inclined in a tubular state from the extension portion 4 side to the notch portion 3 side, and acts by pressing the fingertip 7 a to press the finger 7 against the notch portion 3 side. That is, the fingertip 7a contacts the contact part 5, the extension part 4 covers the bending side of the second joint 7c, and the back side of the finger 7 contacts the vicinity of the notch 3, thereby suppressing the bending operation of the finger 7. . At this time, the point held by the finger 7 using the elastic force of the main body 2 having the notch 3 is as described above.

FIG. 3 is a developed view of the finger fixing device 1 of FIG. The manufacturing method of the finger fixing device 1 will be described with reference to FIG. First, as shown in FIG. 3, the shapes of the main body 2 and the contact portion 5 are cut out from a flat acrylic plate having a predetermined thickness. Prior to the cutout, a plurality of holes 6 are provided in advance on the acrylic plate. After the cutting, the edge portion 2a corresponding to the finger is chamfered. Next, the notch 3 is formed while the flat main body 2 is wound into a tubular shape. Similarly, the flat contact portion 5 is wound into a tubular shape, and the end 5 a is joined to the end 2 b of the main body 2. The finger fixing device 1 is completed by such a process.

However, the present invention is not limited to the above-described manufacturing method. For example, a long tubular member is formed in advance and then cut to form the main body 2 and the abutting portion 5 and join these two members. Various known molding methods, such as a method by injection molding using a mold, are applied.

FIGS. 4 to 6 are perspective views showing other embodiments of the finger fixing device according to the present invention. The finger fixing device 8 shown in FIG. 4 has a notch 1 in the main body 9 similarly to the finger fixing device 1 of FIG.
0, an extension portion 11, a contact portion 12, and a hole portion 13 are provided. The difference from the finger fixing device 1 of FIG. 1 is that the notch 3 of the finger fixing device 1 of FIG. 1 has a length L1, whereas the notch 10 of the finger fixing device 8 of FIG. The length is shorter than L1.

In the first place, in the finger fixing device 1 according to the present invention, the length of the notch 3 is arbitrary, and even a short type such as the notch 10 in FIG. 4 can be sufficiently held on the finger.
Moreover, the short cutouts 10 make it possible to reduce the material as a whole. Further, when the finger fixing device 8 of FIG. 4 is worn on a finger, the amount of exposure of the finger fixing device 8 when viewed from the back of the hand is small, so that the appearance at the time of wearing is lower than that of the finger fixing device 1 of FIG. Be improved. In addition, also in the finger fixing device 8 of FIG. 4, whether to provide the hole 13, the length of the extension 11 (that is, whether to cover both the first joint and the second joint),
Whether or not to chamfer an edge portion corresponding to a finger of the main body 9 is arbitrary as in the case of the finger fixing tool 1 in FIG.

The finger fixing device 14 shown in FIG. 5 has a notch 16, a contact portion 17, and a hole 18 in the main body 15, but does not have an extension unlike the finger fixing device 1 of FIG. . This is intended to reduce a portion requiring special processing such as an extension portion, thereby reducing manufacturing costs. Therefore, one or both of the first joint and the second joint of the finger are covered with the main body 15. However, also in the finger fixing device 14 of FIG. 5, whether the hole 18 is provided, the length of the main body 15 (that is, whether both the first joint and the second joint are covered), the Whether or not to bevel the edge portion corresponding to the finger is arbitrary.

A finger fixing device 19 shown in FIG. 6 has a cutout portion 21 and an extension portion 2 in a main body portion 20, similarly to the finger fixing device 1 of FIG.
2, a contact part 23 and a hole part 24 are provided. The point different from the finger fixing device 1 of FIG.
2 is formed in a tapered shape that expands in diameter. This facilitates insertion of the finger into the finger fixture 19. In the finger fixing device 19 shown in FIG.
4 is provided, the length of the extension 22 (ie, whether both the first joint and the second joint are covered), and whether or not the edge portion corresponding to the finger is chamfered is determined by the finger fixation shown in FIG. It is optional similarly to the tool 1.

The various shapes and combinations of the constituent members shown in the above embodiments are merely examples, and various changes can be made based on design requirements without departing from the spirit of the present invention. For example, in FIG. 1, the notch 3 is provided over the entire length in the longitudinal direction of the main body 2. However, the present invention is not limited thereto. It may be provided on a part of the entire length in the direction.

[0023]

As described above, in the finger fixing device according to the first aspect, since the notch is formed in the longitudinal direction, an elastic force acts in a direction in which the notch is expanded, and this elastic force is used. As a result, the state where the finger is inserted can be maintained, and the bending operation of the finger can be suppressed by the contact portion. In addition, since the elastic force gives a buffering action to the finger, a cushioning material such as a sponge is not required, and it is possible to reduce deterioration of a feeling of wearing when wet with water and to improve durability.

Further, in the finger fixing device according to the second aspect, since the inside and the outside of the finger fixing device communicate with each other by the hole, the hole becomes a ventilation hole so that it can be damp or immersed in water. It acts as a drainer, and the feeling of wearing can be improved.
I do. Since at least a part (including all) of the finger fixing device according to claim 3 is formed to be transparent or translucent, observation of an affected part is easy, and dirt of the finger fixing device itself becomes clear and the degree of contamination is reduced. Confirmation can be easily performed.

In the finger fixing device according to the fourth aspect, since the edge portion which is in contact with the finger is chamfered, it is possible to soften the contact with the skin. Can be further improved.
