Description

A kind of auxiliary arm rehabilitation massage device

technical field

The utility model relates to the technical field of auxiliary rehabilitation medical equipment, in particular to an auxiliary arm rehabilitation massage device.

Background technique

At present, my country has entered the stage of aging, and cardiovascular and cerebrovascular diseases have become a common disease among middle-aged and elderly people over 50 years old, with the characteristics of high prevalence, high disability rate and high mortality rate. There are still more than 50% of survivors of cardiovascular and cerebrovascular diseases who cannot fully take care of themselves.

In 2019, the world-renowned medical journal "The Lancet" once released a survey report, which surveyed the global incidence of cerebral infarction in 2016. The data showed that there were 13.7 million new cerebral infarctions in the world in 2016, and only There are 5.51 million people in China, accounting for nearly 40% of the total, which is equivalent to the total population of a medium-sized city in China. This data can be said to be very staggering. Cardiovascular and cerebrovascular diseases will mostly leave sequelae after treatment. For example, patients with cerebral infarction may have sequelae such as hemiplegia, which greatly affects the patient's limb movement ability.

If the patient's arms, wrists and other parts are inactive for a long time due to hemiplegia and other reasons, the muscles will atrophy or even cause permanent damage. Through active rehabilitation, 90% of patients can regain the ability to walk and take care of themselves, and 30% of them can return to light work. The essential process of rehabilitation of patients with cerebral infarction is "learning, exercising, exercising, and re-learning", which requires patients to cooperate and actively participate. In the acute stage, rehabilitation exercise is mainly to inhibit abnormal primitive reflex activities, restore normal movement patterns, and strengthen muscle strength training.

The following examples are implemented on the premise of the technical solutions of the present utility model, and provide detailed implementation manners and specific operation processes, but the protection scope of the present utility model is not limited to the following examples. The methods used in the following examples are conventional methods unless otherwise specified.

[Example 1]

As shown in FIG. 1 and FIG. 2 , in this embodiment, the upper fixing arm is made of elastic material, so as to clamp the patient's arm without being detrimental to the blood circulation of the patient. The curved groove on the upper arm is lined with soft skin-friendly material, so patients do not need to wear long sleeves for training when the ambient temperature is high.

The first vibration massager is installed in the middle of the upper fixed arm and on both sides corresponding to the biceps of the upper arm of the human body to relieve the muscle tension of the patient. The forward and reverse rotation drives the screw to rotate, so that the vibration massager moves up and down in a short distance; at the same time, the vibration massager can adjust the amplitude to control the massage intensity. By adjusting the massage area and the degree of massage, the patient's upper arm can be recovered and trained in a comfortable state.

The shape of the lower fixed arm is tapered, the side close to the elbow joint is wider, and the side close to the wrist joint is narrower, so as to adapt to the arm shape of the human body and facilitate the fixation of the lower arm. The arc groove of the lower arm is also lined with soft and skin-friendly materials, and two vibration massagers are installed on both sides near the brachioradialis muscle to relieve the brachioradialis muscle tension and relax the patient's fingers. Due to the volume of the brachioradialis muscle It is smaller than the volume of the biceps, so the vibration massager 2 does not need to move, just adjust the vibration amplitude.

Both sides of the connecting ends of the upper fixed arm and the lower fixed arm are provided with an extension arm extending outward to facilitate the movement of the elbow joint and to facilitate the installation of the rotating connecting mechanism.

The rotating connecting mechanism is composed of a connecting motor, a worm wheel, a worm and a transmission bearing. The rotating connecting mechanism drives the lower fixed arm to reciprocate relative to the upper fixed arm, and the reciprocating swing speed can be adjusted by adjusting the speed of the connecting motor.

[Example 2]

As shown in Figures 3 and 4, this embodiment is based on the first embodiment with a lifting support frame. The lifting support frame is composed of a supporting member, a lifting rod and a base; the supporting member is made of elastic material, which is convenient for clamping Tighten the retaining arm. The lifting rod is composed of an upper rod, a lower rod, an adjusting bolt and an adjusting nut. The supporting part and the upper rod are hinged, so that the upper fixed arm can be flexibly rotated, so that the patient can adjust the appropriate posture during use.

Considering that the height of the user's upper arm is different and the sitting posture during use is different, the lifting support frame is used to adjust the height of the device body. The lifting rod adopts a telescopic structure, and the upper rod is moved up and down relative to the lower rod through the cooperation of the adjusting bolt and the adjusting nut, so as to realize the adjustment of the height of the device body.

The lifting rod should be made of materials with high rigidity such as steel pipes, and the remaining parts should be made of light materials to facilitate movement; the four corners of the base are respectively provided with rollers, which are also convenient for movement.

The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited to this. Equivalent replacement or modification of the new technical solution and its concept shall be included within the protection scope of the present invention.
