Description

  The present invention relates to a thumb protection device used for acupressure treatment.

  Acupressure is a surgical procedure that uses a thumb, palm, etc., to press a certain part of the body surface to correct the body's modulation to improve health and contribute to the healing of specific diseases. In acupressure treatment, continuous pressure is applied to acupuncture points scattered on the meridians to release muscles and improve blood circulation. Since the therapist performs the treatment by applying weight pressure to the thumb, it is often hurt, and it is difficult to treat for a long time continuously.

  Conventionally, in order to protect a therapist's thumb, for example, a finger joint protector as shown in Patent Document 1 is known. This finger joint protector has an annular body, an elongated body, and a triangular body between them. After the thumb is passed through the annular body, the elongated body is wrapped around the wrist, and the elongated body is wound around the thumb. Put it on. This protector supports the thumb from the back side of the hand, so that when the thumb is pressed against the target location, tension is generated in the area from the crotch of the thumb and index finger to the wrist. Can suppress upsets.

Japanese Patent Laid-Open No. 2005-42276 JP-A-8-196562

  The prior art protector according to Patent Document 1 shows that the joint connecting the first metacarpal bone of the thumb and the proximal phalanx (metacarpophalangeal joint, hereinafter referred to as the first joint) swings left and right during the treatment. Suppress and protect the first metacarpophalangeal joint of the thumb.

  However, since this protector fixes the thumb with the wrist, the outer shape of the protector is large and makes the patient feel intimidating. In addition, there is a problem that it takes a long time to install.

  An object of the present invention is to provide a small protector that does not give an intimidating feeling to a patient and is easy to wear.

  In the present invention, the first joint is fixed from the palm side with a simple structure, rather than attracting and fixing the thumb from the back of the hand as in Patent Document 1. Patent Document 2 discloses a supporter that can be used for finger tightening, although it is not for treatment. This supporter wraps a support portion around a wrist and tightens the surrounding of a finger from the back side of the hand using this as a fulcrum. Also in this supporter, it becomes a large-sized thing like patent document 1, and time is also required for mounting.

  When the protector is attached, it must be attached with one hand. Therefore, as in Patent Documents 1 and 2, first, a support portion is wound around the wrist and fixed, and the supporter is supported by one hand on the fulcrum. The tightening is done. For this reason, the outer shape of the protector must be large.

The finger joint protector of the present invention includes an arcuate first side that surrounds the periphery of the distal phalanx side end of the proximal phalanx of the thumb, and the longitudinal direction of the proximal phalanx from both front and rear ends of the first side. The front and rear sides extending toward the front side, and the first joint position between the proximal phalanx and the metacarpal bone, both sides extending from the proximal phalanx side to the metacarpal side in an arcuate shape. Fixed to the back side of the base material in the vicinity of the rear end side, a base material having an outer shape surrounded by two side edges, a first bonding member fixed to the front side of the base material in the vicinity of the front side side, and And a second joint member that joins the first joint member in a male-female relationship, and a non-slip member disposed around the base material, and one end of the second side is inside. After extending to the hand bone side, it curves to the first joint side and continues to the rear side, and the other end extends to the metacarpal side and then curves back to the first joint side and curves to the front side. Communicating Is intended to, among sites surrounded by a position of said first joint and said second side edge a front, a position further extending the metacarpal bone in the palm side, pressing on the metacarpal side by a finger It has a support part used for

  Since the protector of the present invention fixes the non-slip fixing portion with the hand on the winding side, it can be wound with force with the other hand, and can be easily wound in tension with one winding operation. . Moreover, since it is small enough to go around the thumb, it does not give the patient a sense of intimidation.

2 is a plan view of the protector 1. FIG. It is a figure which shows the usage method of the protector. It is a figure explaining the external shape of the protector. It is a figure explaining each component part of the protector. FIG. 5 is a diagram showing the operation of protector 1.

Hereinafter, the protector 1 of an Example is demonstrated with reference to drawings.
FIG. 1 is a plan view of a protector 1 according to the present embodiment. In the protector 1, a thread 3 (resin thread) is sewn by overlock stitching with the entire periphery of the base material 6 cut from a piece of leather as a non-slip, and is provided with irregularities. FIG. 1A is the front side of the protector 1 and the front side of the leather. A surface fastener 5 as a joining member is sewn on the right side in the drawing, and a hole 2 is formed on the right side. FIG. B is the back side of the protector 1 and also the leather lining side. On the left side of the figure, a hook-and-loop fastener 4 is sewn, and the hook-and-loop fastener 5 and the male and female are joined together. The hole 2 is further provided on the right side of the surface fastener 5.

  FIG. 2 is a diagram showing how the protector 1 is attached to the thumb. In FIG. 2A, the side of the protector 1 where the hole 2 is provided is placed on the metacarpal bone of the palmar thumb. In that case, it arrange | positions so that the position of the hole 2 may be on a lifeline, and the hole 2 is pressed down with a middle finger. The tip of the middle finger enters the hole 2, and the slip of the middle finger is completely stopped around the hole 2. Next, as shown in FIG. 2B, hold the opposite end of the protector 1 with the other hand, wrap it around the position of the proximal phalanx from the back of the thumb, and pull the surface fasteners 4 and 5 together while pulling strongly. Join. Meanwhile, the periphery of the hole 2 pressed by the middle finger serves as a finger fixing portion, which acts as a fulcrum, and the protector 1 surrounds the thumb in a tense manner (FIG. 2C). The protector 1 is completely attached by removing the middle finger. Since the protector 1 can be fixed with the middle finger around the hole 2 as a fulcrum, the protector 1 can be easily wound tightly with only one hand.

  FIG. 3 is a diagram showing the relationship between the shape of the protector 1 (also the outer shape of the base material 6) viewed from the back side and the joint of the thumb. In the figure, the position corresponding to the first joint is indicated by a two-dot broken line D1, and the position of the joint between the distal phalanx and the proximal phalanx (interphalangeal joint, hereinafter referred to as the second joint) is indicated by a two-dot broken line D2. It is.

  For convenience of describing the outer shape of the protector 1, the left side in the figure is referred to as a first side 1a, the upper side in the figure is referred to as a front side 1b, the rear side is referred to as a rear side 1c, and the other second side 1d. . Each of these sides is smoothly connected. For convenience of explanation, the upper side of FIG. 3 is the front side of the protector 1 and the lower side is the rear side.

  When the first side 1a is wound around the thumb, it is located between the first joint position D1 and the second joint position D2 and not within the second joint position D2 and within the range of the proximal phalanx. It is an edge. Since the proximal phalanx of the thumb has a shape that swells on the second joint side, the first side 1a has a shape that wraps around the joint at the base of this bulge. Specifically, when the thumb of the proximal phalanx part (excluding the joint-side bulge) is regarded as a tapered truncated cone, the arcuate shape is drawn along the upper side of the side surface when the truncated cone is developed. In order to wrap the base of the joint side bulge of the proximal phalanx, the unevenness of the resin thread 3 applied to this part bites into the meat part in front of the second joint and stabilizes the protector.

The front side 1b and the rear side 1c are sides up to the first joint position D1 along the cut sides E1 and E2 on the side surface when the truncated cone is developed when the truncated cone is regarded as described above. Further, the second side 1d extends from the position P corresponding to the central portion of the first side 1a to the metacarpal side in an arch shape on both sides and extends from the front and rear inflection positions Q1, Q2 to the first joint position D1 side. And is continuous to the front side 1b and the rear side 1c at the first joint position E1. In particular, on the front side (upper side in the drawing) of the protector 1, the second side 1d extends beyond the inflection position Q1 and extends further to the metacarpal side than the rear side, and then curves in a return shape. The second side 1d enters the proximal phalanx at the position P from the first joint position D1, and is positioned above the metacarpal bone before and after that. The position P corresponds to the highest part on the back side of the hand when the first joint is bent. Since the first joint side of the proximal phalanx also has a shape that swells, by entering the proximal phalanx side from the first joint position D1 at the position P, the unevenness of the resin thread 3 that has been stitched over to this part is The bulge-shaped tail bites into the meat on the proximal phalanx and stabilizes the protector.

  In the figure, O is the position of the apex when the thumb of the proximal phalanx position is regarded as a truncated cone. Further, the first joint position D1 crosses substantially the center of the surface fasteners 4 and 5. In the drawing, a broken line 1 ′ indicates a positional relationship when the protector 1 is wound around the thumb and the surface fasteners 4, 5 are joined together. In this manner, the hook and loop fasteners 4 and 5 themselves press the front and rear with the first joint interposed therebetween. A broken line C is a line connecting the hole 2, the surface fastener 5, and the surface fastener 4. With the holes 2 as the front side, the surface fastener 5 and the surface fastener 4 are arranged in this order.

  As shown in FIG. 4, the protector 1 can be roughly classified into four parts. First, it is the site | part 10 (in the figure medium shade location) enclosed by the 1st side 1a, the front-and-back side 1b, 1c, and the position D1 of the 1st joint. This part 10 functions as a winding band around the thumb. On the rear side, a part surrounded by the second side 1d and the position D1 of the first joint is a first fixing part 11 (light shading part). On the front side, the portion surrounded by the second side 1d and the position D1 of the first joint can be divided into two, the second fixing portion 12 (thin light and dark portion) on the first joint position D1 side, and the hole 2 This is the side support portion 13 (dark shading portion). The first fixing portion 11 and the second fixing portion 12 are portions that overlap each other on the metacarpal bone when the protector 1 is wound around the thumb. Moreover, the support part 13 is a part which becomes a fulcrum fixed by the middle finger when the protector 1 is wound around the thumb. Since the support portion 13 is configured to extend further on the metacarpal bone on the palm side from the second fixing portion 12, the first fixing portion 11 is covered when the first fixing portion 11 is covered on the second fixing portion 12. The periphery of the part 11 does not directly hit the palm.

  FIG. 5 is a diagram illustrating a state where a protector is attached to the thumb. In the figure, B1 is the distal phalanx, B2 is the proximal phalanx, B3 is the metacarpal bone, T1 is the flexor (the figure shows the long thumb flexor), and S1 to S3 are the sheaths. The protector 1 is indicated by a broken line.

  In a state where the protector 1 is wound around the thumb, the surface fasteners 4 and 5 of the protector 1 and the first and second fixing portions 11 and 12 are overlapped to increase the thickness and fix the first joint. At this time, muscles on the palm side of the metacarpal bone such as the long flexor flexor and the short flexor flexor are compressed so that they cannot be moved easily. The more the thumbs are bent, the more the fixing parts 11 and 12 press the muscles on the palm side of the metacarpal bone, so that the first joint of the thumbs cannot move by its own intention. Applying pressure to the joints of the fingers other than the thumb and the muscles directly below it does not significantly affect the bending of the fingers. However, if the first joint of the thumb and the muscle of the palm part of the metacarpal bone are pressed down, the first joint of the thumb is not easily moved and becomes a rod shape by winding the protector 1. Thus, as long as the hook-and-loop fasteners 4 and 5 are not disconnected, the protector 1 is not relaxed by the movement of the thumb joint.

  As described above, in this embodiment, since the periphery of the hole 2 of the protector 1 is fixed on the side of the hand around which the protector 1 is wound, it can be wound with force with the other hand, and one winding operation is performed. Can be easily wrapped in tension. Moreover, since the protector 1 is small enough to go around the thumb, it does not make the patient feel intimidating.

  Further, when the therapist wearing the protector 1 performs the operation with the weight pressure applied to the thumb, the warping force is intermittently applied to the proximal phalanx. Since the muscles around the phalanx are fixed, the load on the base phalanx is reduced and fatigue fracture is difficult. Further, since the first joint is fixed by the protector 1 from the inside, the shaking of the joint is reduced.

  In the above embodiment, leather is used as the base material of the protector 1, but it may be artificial leather, cloth, non-woven cloth, or flexible material such as rubber or silicone resin. Moreover, although the hole 2 was opened for fixing with an index finger, a non-slip may be attached. Further, a slip stopper may be provided around the base material of the protector 1 instead of sewing the periphery with the resin thread 3.
