JP2000334067A - Automatic ankle joint exercising machine usable with laying on one's back - Google Patents

Abstract

PROBLEM TO BE SOLVED: To allow a patient to carry out rehabilitation on his/her ankle joints with laying on his/her back using an ankle joint exercising machine, in which right and left foot pedals connected to move relatively by a string are brought into contact with the feet of the patient, and allowing the patient to carry out rehabilitation as if he/she takes a walk using a seesaw principle based on a physical reactive force. SOLUTION: A pair of right and left automatic ankle joint exercising plates 1, 2 is attached to a support base 3 using a pair of spring hinges 4. One end of a pair of right and left coil springs 6 is connected to the plates 1, 2 respectively and the other end of the spring 6 is connected to a pair of right and left spring base plates 5 attached to the support base 3 respectively. The plates 1, 2 are connected so that they moves relatively like a seesaw using a string 7 via a pair of right and left bearings 8 attached on the support base 3. When the plates 1, 2 are pressed alternately by the feet of a patient lying on his/her back, the both spring hinges 4 and both coil springs 6 give resistant force and applying force alternately to the feet, realizing a virtual walking exercise.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic ankle joint flexion / extension machine which is carried out while lying in a supine position. It is an object of the present invention to provide an inexpensive and simple automatic ankle flexion / extension machine that can be rehabilitated as soon as possible with the help of a caregiver or the patient himself while lying down.

[0002]

2. Description of the Related Art Hitherto, many rehabilitation devices have been proposed for restoring the function of a human body suffering from a vascular system or other diseases. The present applicant also proposed in 1998 Patent Application No. 69209 a seesaw-type human body function recovery device to measure the function of this kind of illness patient at an early stage, and to achieve a reasonable purpose. Was.

[0003]

However, since the above-mentioned seesaw type human body function recovery device is used after a considerable recovery from a medical condition, there is a problem in the case of acute rehabilitation of a patient with cerebral infarction or the like when the patient is unconscious. Devices that require early treatment, such as prevention of secondary disorders, stiffening of joints, and muscle loss, have been somewhat inconvenient and less effective.

[0004]

SUMMARY OF THE INVENTION In view of the above, the present invention provides a simple and convenient method for performing exercise therapy such as ankle bending and stretching exercise while sleeping with the help of a caregiver even in the worst case where the patient is unconscious. It is intended to provide an inexpensive device of this kind.

That is, an ankle joint bending and stretching exercise machine is mounted under both ankles of a patient who lies on a bed or a futon, utilizing the reaction force of physical properties, applying the principle of a seesaw, and connecting the left and right footrests with strings. It is configured to be able to give the same motion as the walking motion to the ankle joint by interlocking, performs exercise therapy from the onset of the disease with the help of the patient himself or the caregiver, bedridden, bedsore,
The present invention is characterized in that hardening of the ankle joint and the like are prevented, and the thrombus generated is fluidized to achieve functional recovery.

[0006]

Thus, the automatic ankle flexion / extension machine of the present invention is attached to an acute or right angle type footrest with the help of a patient or a caregiver who lies on a bed or futon. Using the reaction force of physical properties, the seesaw principle is applied.By connecting and linking the left and right footrests with a string, the same movement as walking is transmitted to the ankle, and the ankle joint is bent and stretched. It is designed to prevent stiffness, muscle stiffness, bedsores, etc., as well as improve blood flow and allow natural flexion and extension of the ankle, so that patients in the recovery phase can easily maintain rehabilitation. Even if the patient is unconscious and can perform early and reasonable rehabilitation by the caregiver while still lying on his back, it is possible to prevent various after-effects after the first-stage illness and to relatively easily and promptly improve the human body function. You can recover. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0007]

1 and 2 show an embodiment of the present invention, in which a joint bending and stretching exercise machine is mounted under an ankle of a patient who lies on a bed or futon.

[0008] When the left foot (2) of the patient lying forward is put forward, the right foot (1) becomes L-shaped due to the reaction force (4) (6) and the seesaw principle (1) (2). It is configured to be.

When the left foot (2) of the patient lying forward is put forward, the right foot (1) becomes L-shaped due to the reaction force (4) (6) and the seesaw principle (1) (2). At the same time, the left foot (2) returns to its original state due to the reaction force, the right foot (1) protrudes forward by the seesaw principle, and the bending motion of the right and left feet is automatically repeated.

The flexion / extension movement of the ankle joint acts like a walking movement even when the patient is in a supine position, and improves the blood flow by repeatedly pressing the upper joint of the ankle joint and contracting and relaxing the soleus and abdominal muscles. It works to prevent stiffening of the joint and bedsores, fluidization of thrombus, and the like.

[00011]

According to the configuration and operation of the first half, the ankle flexion / extension machine of the present invention can flex and extend the ankle joint by natural force as shown in the first embodiment, and Since the same exercise as walking can be obtained, the following effects are provided. (1) The structure is simple and the function recovery effect is large. (2) Since the machine can be operated by natural force, a patient in the early stage of recovery can perform rehabilitation by himself. (3) Since the operation can be performed while the patient is lying on his back, the burden on the patient and the caregiver is small, and rehabilitation can be performed from the onset of the onset of the disease even if the patient is not conscious, and the effect is large. (4) Milking.
An action effect is generated to improve blood flow, prevent stiffening of the joint, bedsore, etc., and help fluidize the thrombus. (5) Inexpensive and easy to use.

[Correction contents]

[0008] An ankle flexion / extension machine having such a structure is worn under the ankle of a patient who lies on a bed or futon, and is cared for so that rehabilitation is performed as soon as possible. That is, the patient who first lays down puts his ankles on the abutment (3) and the footrests (1) and (2) as shown in the figure, and starts the rehabilitation exercise by himself or herself. In this exercise, when the patient's left footrest or left foot (2) is brought forward, the right foot (1) will exert a reaction force between the spring hinge (4) and the coil spring (6) and the footrest ( 1) Due to the seesaw movement of (2), the leg and ankle become L-shaped, and at the same time, the left foot (2) returns to its original state by the spring reaction force, and the right foot (1) moves forward. The bending motion of the left and right ankles is automatically repeated.
