Abstract

PROBLEM TO BE SOLVED: To move fingers and finger joints without imposing a burden on the hand/fingers and the finger joints. SOLUTION: A curtain runner 3 is installed on an outrigger 2, fingers are towed via this curtain runner, and a usual towing (fulcrum)-fixed outrigger is made movable. The outrigger 2 is also curved so that the curtain runner 3 interlocks with a finger movement so as to change a tow and the towing direction in response to a movement of bending and stretching of the fingers.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a splint device which is used (worn) by a person having a hand or finger injury for treatment or rehabilitation treatment / training.

[0002]

2. Description of the Related Art In a conventional traction type sprint (traction type dynamic sprint), a traction (fulcrum) for pulling a finger is fixed, and there is no problem in holding a finger in an extended position. When the finger is bent (bent), the traction (fulcrum) is fixed, so the finger is in an unreasonable traction or traction direction. In the movement of the finger joint, the traction and the traction direction narrow the joint cavity. there were. In addition, since the traction (fulcrum) is fixed, as the angle at which the finger is bent (bent) increases, the rubber being pulled is stretched and the force is increased, and the finger is more resistant to bending (bending). I needed power.

SUMMARY OF THE INVENTION According to the present invention, when a person who has suffered a hand or finger damage by putting on a tow-type dynamics sprint and moving his or her finger, the finger may be forced or cannot It is an object of the present invention to provide a dynamic sprint with a movable traction (fulcrum) outrigger that performs smooth traction (fulcrum) movement by using a movable traction (fulcrum) and does not impose a burden on a moving joint and a moving joint.

[0004]

A curtain runner (or device with small wheels) (3) is attached to an outrigger (2) for pulling a finger, and the curtain runner (or device with small wheels) is attached. (3) to pull the finger through and outrigger (2)
Is characterized in that the curtain runner (or a device with small wheels) (3) is curved so that it moves smoothly in accordance with the movement of the finger even while the finger is being pulled.

Further, the shape of the outrigger (2) is changed to a curtain runner (or a tool with small wheels) (3).
The shape is such that it can run smoothly without coming off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The dynamic sprint with movable outriggers of the present invention will be described in detail with reference to the drawings.

FIGS. 1 to 3 are a side view, a front view, and an oblique view of a dynamic sprint with a movable traction (fulcrum) outrigger of the present invention. FIG. 4 shows the movement of the curtain runner (or the instrument with small wheels) (3), which is the traction (fulcrum) when the finger is bent (bent), and the change (movement) in the traction direction. .

The dynamic sprint with movable towing (fulcrum) movable outriggers is connected to a curtain runner (or a device with small wheels) (3) by rubber (or a spring or rubber-like material) (7). The mechanism is such that the finger is pulled through the cuff (8).

When the finger is bent (bent), the curtain runner (or a device with small wheels) (3) is structured to move forward in accordance with the movement of the finger and change the traction direction.

When returning the finger from the bent position (bent state) to the original extended position (the finger is extended), a curtain runner (or a device with small wheels or the like) is used.
A mechanism for returning the finger to the extended position (in a state where the finger is extended) by the contraction force of rubber (or a spring or rubber-like material) (6) tied between (3) and the stopper (4). ing.

An outrigger (2) as shown in FIG. 1 is used so that a curtain runner (or a device with small wheels) as a traction (fulcrum) can move smoothly in response to the movement of a finger. The mechanism has a curved shape.

The outrigger (2) is a curtain runner (or a device with small wheels) (3)
However, as shown in FIG. 2 or FIG. 3, the mechanism is hollowed out so as to be movable.

First, the structure of a dynamic splint with movable outriggers for traction (fulcrum) of the main body will be described with reference to FIG.

The dynamic sprint with movable towing (fulcrum) movable outrigger is a splint (1) for mounting on a forearm and a hand, an outrigger (2) attached to the splint, and an outrigger (2). It consists of a curtain runner (or a device with small wheels, etc.) (3), which is also a traction (fulcrum), and a cuff (8) connected to it by rubber (7). The curtain runner (or device with small wheels) (3), which is also the traction (fulcrum), is a stop device (4) and rubber (or a spring or rubber-like material) (6)
Are tied together.

Further, a curtain runner (or a device with small wheels, etc.) which is also a traction (fulcrum) (3)
Can move in the outrigger (2) by the movement of the finger being pulled through the cuff (8), and can change the direction in which the finger is pulled as shown in FIG.

The dynamic sprint with movable traction (fulcrum) movable outrigger can hold a hand or a finger in an extended position (extended state), and at the same time, moves or joints of a finger such as bending (bending) the finger. During the exercise, the curtain runner (or equipment with small wheels) (3), which is also the traction (fulcrum), moves,
The movement of the finger in the traction direction that narrows the joint cavity and the bending of the finger do not require much force as the bending is performed. Even if the finger is bent (bent) while being pulled, the burden on the joint is reduced Able to exercise the finger flexion / extension (bending / extension) with little and no excessive force.

[0017]

As described above, according to the dynamic sprint with outriggers of the present invention, the following effects can be considered.

The dynamic sprint with movable tow (fulcrum) movable outriggers of the present invention is used when a person with a damaged hand or finger is used for treatment, rehabilitation treatment or training, in which the finger is pulled and extended (extended). In addition to the above, when the towed finger is moved (bent), the towing (fulcrum) moves in response to the movement of the finger, and the towing direction changes accordingly. Therefore, finger and finger joint movements can be performed smoothly. The dynamic sprint with towing (fulcrum) movable outrigger of the present invention
Conventional traction (fulcrum) in fixed dynamic sprints, the narrowing of the joint cavity and the need for strong force to bend the finger, which are seen during the movement of the finger while being pulled, traction by bending (bending) of the finger It solves problems such as direction incompatibility and misalignment of the cuff, and can perform ideal movement even while the finger or joint movement is being pulled.
