Description

[Detailed description of the invention] [Industrial application field] This invention relates to a sanding block used in functional recovery occupational therapy for patients with upper limb paralysis.

[Conventional technology]

Patients who have paralysis in their upper limbs due to cerebral hemorrhage, etc.
If functional recovery occupational therapy is not performed in the early stages, paralysis will progress and the forearm will become externally rotated, making recovery difficult. To prevent this, it is important to perform occupational therapy that requires internal rotation of the forearm.

Sanding has traditionally been widely used as part of occupational therapy to restore function for patients with upper limb paralysis. Sanding is a type of woodworking occupational therapy that aims to help paralyzed patients recover their motor function by having them sandpaper a wooden board.

In this sanding process, a sanding block is a device that allows paralyzed patients to perform the sanding work effectively. This sanding block has sandpaper attached to the bottom of a piece of wood, and grip bars are provided on the top and sides of the piece of wood to make it easier for the patient to grip it. The patient then holds a wooden stick and sands another wooden board.

Fig. 3 is a perspective view showing a conventional sanding block, Fig. 3a shows one with a horizontal grip bar, Fig. 3b shows one with a vertical grip bar, and Fig. c shows a sanding block used by a patient who is unable to grasp the handgrip. In FIGS. 3a to 3c, 1 is a slide block made of wood or the like, 2 is a grip block also made of wood, 3 is a grip bar, and 9 is a slide block for fixing the patient's hand to the slide block 1. For example, the fixing band is made of flexible adhesive tape or leather, and its fixing portion 9a is fixed to the slide block 1.

The patient performing the training places the above-mentioned sanding block on the top plate of a table prepared separately so that the inclination of the top plate can be changed, and either grips the grip bar 3 or holds the sanding block with the fixing band 9 with the hand. 1 and slide the sanding block back and forth for training. In this case, sanding training may be carried out by wrapping sandpaper around the slide block 1, placing a sand bag on the sanding block, or changing the slope of the table top, depending on the patient's disability and degree of functional recovery. Change the difficulty level (exercise load).

[Problem that the invention attempts to solve]

In the conventional sanding block as described above, the grip bar 3 is only installed horizontally or vertically, so patients who cannot grip the grip bar 3 only at an angle between horizontal and vertical cannot perform the work. The problem was that therapy could not be performed. Another problem was that it was not possible to perform training in which the angle of the grip bar 3 was gradually changed to gradually change the workload.

This invention was made to solve this problem, and the object is to provide a sanding block that can freely change the angle of the grip block with respect to the slide block.

[Means for solving problems]

In the sanding block according to this invention, one end of the grip block is rotatably connected to the end of the slide block, and the other end of the grip block is connected by a stay member whose length can be changed. Alternatively, the central portion and the central portion of the slide block may be connected to each other, and the angle of the grip block relative to the slide block may be freely adjusted.

[Effect]

In the sanding block of this idea,
Since the angle of the grip block relative to the slide block can be freely adjusted, occupational therapy can be performed even on patients who cannot receive occupational therapy using conventional horizontal or vertical grip bars. Also, depending on the degree of recovery of the patient's upper limb function,
Adjustments can be made to train, and recovery can be accelerated.

〔Example〕

Fig. 1 is a front view showing a sanding block which is one embodiment of this invention, Fig. 2 is a front view and partially enlarged side view showing a sanding block which is another embodiment of this invention, and Fig. The same or corresponding parts as those in the figures are indicated using the same reference numerals, and detailed explanation thereof will be omitted. In the figure, 4 is a hinge that rotatably connects the slide block 1 and the grip block 2, 5 is a stay member, and a turnbuckle 51,
It consists of a knob 52, a left-handed threaded rod 53, a right-handed threaded rod 54, etc., and when the turnbuckle 51 is rotated in one direction using the knob 52 formed in the center of the turnbuckle 51, it becomes shorter, and when rotated in the other direction, it becomes longer. Reference numeral 6 designates a connecting metal fitting that rotatably connects one end of the stay member 5 to the grip portion block 2, and numeral 7 represents a central metal fitting that connects the other end of the stay member 5 to the central portion of the slide block 1 in a rotatable manner. With the above structure, the angles of the left and right hand grip blocks 2, 2 with respect to the slide block 1 can be changed independently. Therefore, the angles of both grip bars 3, 3 can also be changed independently. Note that 10 is sandpaper attached to the bottom surface of the slide block 1. Figure 2a
2 is a front view of another embodiment, and FIG. 2b is an enlarged side view showing the relationship between the support fitting and the stay member. This sanding block uses a set of stay members 5 and is configured so that the left and right grip blocks 2, 2 can be set at the same angle at the same time, and has a long hole 8a.
The turnbuckle 5 is
1. A central knob 52 is always supported at the center of the slide block 1, and the turnbuckle 51 is rotated by the knob 52 to change the angle of the grip blocks 2, 2, so that the grip bar 3 The angle can be changed.

In both of the above-mentioned embodiments, instead of the grip bar 3, a plate-shaped part equipped with a fixing band 9 as shown in FIG. It can be used as a sanding block. Further, the variable range of the angle can be set to various ranges by changing the maximum length of the stay member 5 and the mounting positions of the connecting fitting 6 and the central fitting 7.

[Effect of idea]

As explained above, this device is constructed so that the angle of the grip block with respect to the slide block can be freely changed in the sanding block. Therapy can be performed. Furthermore, the angle of the grip block can be changed in accordance with the progress of functional recovery, allowing fine-grained occupational therapy to be performed.
