Description

The present invention relates to a left-right dual-purpose wrist supporter for fixing an injured wrist such as a fracture or a sprain by using a splint, a palm side cine and a dorsal cine.

In the event of a wrist fracture or sprain, a wrist supporter (wrist sprint) with a splint is used to fix the injured area.
As a conventional wrist supporter, for example, one disclosed in "Wrist splint structure" of Patent Document 1 is known. This uses three upper and lower straps (supporter body) with hook-and-loop fasteners, and the splint on the palm side (palm side splint) and the splint on the back side (back side splint) are attached from the injured hand to the forearm. It is a supporter for both left and right that holds up to the part from the back of the palm and fixes it.

As a left-right dual-purpose structure in Patent Document 1, one thin strap body that fixes the distal end (tip) of each of the two attachments to the hand and the middle portion of each attachment are fixed to the wrist. A gap is formed between the wide strap body on the distal side for passing the left and right thumbs. Therefore, when attaching this wrist supporter to the left hand, the thumb of the left hand is extended from the gap on the left side of the distal end of the appendage on the palm side, and when attaching this wrist supporter to the right hand, The thumb of the right hand is extended through the gap to the right of the distal end of the palm side spear.

Japanese Patent No. 4314438

However, in the wrist supporter of Patent Document 1, as a structure for both left and right, a thin strap body and a wide strap body on the distal side are separated from each other, and the right part of this gap is the right thumb through hole and the left side. The part was used as a left thumb through hole.
Therefore, in the part facing the wrist supporter's hand, a large hole appears on the side opposite to the side through which the thumb is inserted, regardless of whether it is attached to either the left or right hand, and the supporter's hand The fixing force, and eventually the fixing force of the wrist, was greatly reduced.

In addition, the two splints are used so as to sandwich the injured part of the wrist from the back of the palm. At this time, the splint on the palm side is located near the MP joint (third joint at the base of the finger) of these fingers in order to secure a large range of motion of the four fingers from the little finger to the index finger. The distal end of the finger (tip on the fingertip side) is placed.
On the other hand, since the dorsal splint needs to fix the MP joint to limit the dorsiflexion of the wrist, the distal end thereof is ahead of the distal end of the volar splint (toward the fingertip). It was necessary to place it in a position facing the MP joint.
It goes without saying that it is preferable that the two splints have the same size from each other from the viewpoint of material procurement and cost.

Therefore, as a result of diligent research, the inventor made one end of the supporter body in the length direction (perspective direction of the upper limbs) in order to make it a left-right dual-purpose wrist supporter that does not cause a decrease in the fixing force of the supporter body, and eventually the wrist. The left wrist through hole is formed in the left hand, while the right wrist through hole is formed in the other end in the length direction. When using, the length of the left and right wrist supporters is adjusted according to the left and right hands to be worn. It was found that the direction of the proximal side and the distal side of the direction should be changed.
In addition, both ends in the length direction of the dorsal part of the supporter body so that the MP joint can be fixed by the dorsal splint to limit the dorsiflexion of the wrist when the left and right wrist supporters are attached to either the left or right hand. It was found that all of these problems could be solved by arranging a pair of positioning pockets for accommodating the proximal end of the dorsal splint on the inner surface of the portion, and completed the present invention.

According to the present invention, even in a left and right wrist supporter having two thumb through holes in the supporter body, when the supporter is used, the holding force of the hand part does not decrease due to the thumb through holes on the unused side, and the palm Despite using a dorsal cine of the same size as the side cine, the distal end of the dorsal cine provides sufficient wrist dorsiflexion regardless of whether the left and right wrist supporters are attached to either the left or right hand. The purpose is to provide a left and right wrist supporter that can be restricted to.

The present invention relates to a left-right dual-purpose wrist supporter for fixing an injured wrist such as a fracture or a sprain by using a splint, a palm side cine and a dorsal cine.

In the event of a wrist fracture or sprain, a wrist supporter (wrist sprint) with a splint is used to fix the injured area.
As a conventional wrist supporter, for example, one disclosed in "Wrist splint structure" of Patent Document 1 is known. This uses three upper and lower straps (supporter body) with hook-and-loop fasteners, and the splint on the palm side (palm side splint) and the splint on the back side (back side splint) are attached from the injured hand to the forearm. It is a supporter for both left and right that holds up to the part from the back of the palm and fixes it.

As a left-right dual-purpose structure in Patent Document 1, one thin strap body that fixes the distal end (tip) of each of the two attachments to the hand and the middle portion of each attachment are fixed to the wrist. A gap is formed between the wide strap body on the distal side for passing the left and right thumbs. Therefore, when attaching this wrist supporter to the left hand, the thumb of the left hand is extended from the gap on the left side of the distal end of the appendage on the palm side, and when attaching this wrist supporter to the right hand, The thumb of the right hand is extended through the gap to the right of the distal end of the palm side spear.

Japanese Patent No. 4314438

However, in the wrist supporter of Patent Document 1, as a structure for both left and right, a thin strap body and a wide strap body on the distal side are separated from each other, and the right part of this gap is the right thumb through hole and the left side. The part was used as a left thumb through hole.
Therefore, in the part facing the wrist supporter's hand, a large hole appears on the side opposite to the side through which the thumb is inserted, regardless of whether it is attached to either the left or right hand, and the supporter's hand The fixing force, and eventually the fixing force of the wrist, was greatly reduced.

In addition, the two splints are used so as to sandwich the injured part of the wrist from the back of the palm. At this time, the splint on the palm side is located near the MP joint (third joint at the base of the finger) of these fingers in order to secure a large range of motion of the four fingers from the little finger to the index finger. The distal end of the finger (tip on the fingertip side) is placed.
On the other hand, since the dorsal splint needs to fix the MP joint to limit the dorsiflexion of the wrist, the distal end thereof is ahead of the distal end of the volar splint (toward the fingertip). It was necessary to place it in a position facing the MP joint.
It goes without saying that it is preferable that the two splints have the same size from each other from the viewpoint of material procurement and cost.

Therefore, as a result of diligent research, the inventor made one end of the supporter body in the length direction (perspective direction of the upper limbs) in order to make it a left-right dual-purpose wrist supporter that does not cause a decrease in the fixing force of the supporter body, and eventually the wrist. The left wrist through hole is formed in the left hand, while the right wrist through hole is formed in the other end in the length direction. When using, the length of the left and right wrist supporters is adjusted according to the left and right hands to be worn. It was found that the direction of the proximal side and the distal side of the direction should be changed.
In addition, both ends in the length direction of the dorsal part of the supporter body so that the MP joint can be fixed by the dorsal splint to limit the dorsiflexion of the wrist when the left and right wrist supporters are attached to either the left or right hand. It was found that all of these problems could be solved by arranging a pair of positioning pockets for accommodating the proximal end of the dorsal splint on the inner surface of the portion, and completed the present invention.

According to the present invention, even in a left and right wrist supporter having two thumb through holes in the supporter body, when the supporter is used, the holding force of the hand part does not decrease due to the thumb through holes on the unused side, and the palm Despite using a dorsal cine of the same size as the side cine, the distal end of the dorsal cine provides sufficient wrist dorsiflexion regardless of whether the left and right wrist supporters are attached to either the left or right hand. The purpose is to provide a left and right wrist supporter that can be restricted to.

The invention according to claim 1 is a substantially rectangular body having a length covering from the wrist to the forearm, and when the hand is folded by a virtual line extending in the length direction and sandwiches the portion of the arm.
