Description

Technical Field

[0001] The invention relates to the field of rehabilitation training devices, and in particular to a rehabilitation training device for foot pressure sores. Background Art

[0002] Pressure sores, also known as pressure ulcers and bedsores, are caused by long-term pressure on local tissues, which leads to continuous ischemia, hypoxia, and malnutrition, resulting in tissue ulceration and necrosis. Skin pressure sores are a common problem in rehabilitation treatment and nursing. According to relevant literature reports, about 60,000 people die from pressure sore complications each year. Pressure sores usually occur due to external pressure, when the skin is soaked by sweat, urine and feces after abrasion, and when local skin blood circulation is not good. At the same time, pressure sores will also occur when the whole body is in poor nutritional status and the skin resistance is reduced.

[0003] Foot pressure sores are pressure sores that occur on the feet. At present, patients with initial pressure sores can achieve certain therapeutic and rehabilitation effects after a gentle massage. The existing massage for patients with foot pressure sores uses manual massage. Some massagers have different levels of massage pressure, which may make the person being massaged feel pain. More serious cases may aggravate the foot pressure sores, which is not worth the cost.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The provided compression plate and support plate can enable the patient to complete the rehabilitation training of foot pressure sores while lying on the bed. The provided compression plates and movable columns on both sides can clamp the two sides of the bed board. The provided movable columns and bolts can enable the device to be fixed in front of the bed. The front sole compression plate and the rear sole compression plate can enable the patient to determine the position of the disease. The provided front sole compression plate and the rear sole compression plate can enable the patient to press the corresponding part to preliminarily determine the position of the disease. The provided distance detection and positioning circuit can determine the appropriate position of the support plate. If the distance is too close or too far, an alarm will be issued;

[0022] 2. The pressure on the forefoot pressure plate or the rear foot pressure plate can be transmitted through the provided mounting column and the matching shell, so that the positioning column is subjected to the corresponding pressure position. When the forefoot pressure plate or the rear foot pressure plate is subjected to pressure, the provided slide groove can exert pressure on the pulley surface, so that the pulley moves on the slide groove surface. During the movement of the pulley, the adapter block transmits the position of the force, thereby driving the guide block to rotate in the matching shell through the rotating shaft. During its rotation, the positioning column will also rotate back and forth. Since the surfaces of the forefoot pressure plate and the rear foot pressure plate are also subjected to pressure, the compression springs on both sides will be squeezed, thereby driving the positioning column to move downward, so that the electrode head on the surface of the positioning column contacts the electrode plate and leaves a position on the surface of the electrode plate;

[0023] 3. The electrode head and the electrode plate are in contact with each other and leave a position on the surface of the electrode plate, so that the position left by the conductive plate and the electrode head can be recorded. After leaving the position, the conductive seat can send the conductive position of the electrode plate to the valve. At this time, the valve controls the water valve to open according to the conductive position of the electrode plate and the center of the conductive position corresponding to it, which is a non-conductive position. Since the patient will feel pain at the affected position, the patient can apply force to the affected area around the affected area to press the forefoot pressure plate or the backfoot pressure plate. The center of several pressed areas that are not pressed is the affected area where force cannot be applied. By controlling the valve in this area to open, the water pump can be The valve controls the flow of water in and out of the water pipe. When the water pump pumps water back and forth, the bag will swell or deflate, making the massage more gentle. At the same time, because the water passing through the transfer block is heated and then enters the bag through the water pipe, the patient will feel warm and more comfortable during the massage. It can also play a role in activating blood circulation, which is beneficial to the patient's recovery. The conductive connecting plug can make the bags in the same group conduct to each other, and will not cause a single bag to swell or deflate to stimulate the diseased part. At the same time, the non-conductive connecting plug can prevent the water flow from being transmitted to all bags, so that the rehabilitation massage can be more targeted.

Since the patient will feel pain at the affected position, the patient can apply force to the affected area around the affected area to press the forefoot pressure plate (2) or the rear foot pressure plate (3). The non-pressed center of the pressed area is the affected area where force cannot be applied. By controlling the valve (30) in this area to open, the pain can be relieved. The water pump (27) controls the flow of water from the inside of the water pipe (31) to the valve (30). When the water pump (27) pumps water back and forth, the bag (23) will also swell or deflate, making the massage more gentle. At the same time, because the water in the transfer block (28) is heated and then enters the inside of the bag (23) through the water pipe (31), the patient will feel warm and more comfortable during the massage. At the same time, it can also play a role in activating blood circulation, which is beneficial to the patient's recovery. The conductive connecting bolt (26) can make the inside of the bags (23) in the same group conduct to each other, so that a single bag (23) will not swell or deflate to stimulate the diseased part. At the same time, the non-conductive connecting bolt (25) can prevent the water flow from being transmitted to the inside of all bags (23), so that the rehabilitation massage can be more targeted.

[0056] It should be noted that the present invention is a rehabilitation training device for foot pressure sores. When in use, the patient is first made to lie on the bed. The support column (7) is moved forward or backward according to the length of the patient's legs. When a suitable position is determined, the provided pressing plate (8) and the movable column (9) can clamp the two sides of the bed board. The movable column (9) and the bolts can fix the device in front of the bed, so that the patient can complete the rehabilitation training of foot pressure sores while lying on the bed. Before the patient places his feet on the front sole pressure plate (2) and the rear sole pressure plate (3), a disposable gasket (29) is placed in the engaging groove (4) in advance. After the placement, the patient applies pressure to the front sole pressure plate (2) and the rear sole pressure plate (3) in turn according to his own situation. The front sole pressure plate (2) and the rear sole pressure plate (3) are pressed together. When the front sole pressure plate (2) or the rear sole pressure plate (3) is subjected to pressure, the provided slide groove (21) can exert pressure on the surface of the pulley (22), so that the pulley (22) moves on the surface of the slide groove (21). During the movement of the pulley (22), the adapter block (12) transmits the position of the force, thereby driving the guide block (14) to rotate in the matching shell (13) through the rotating shaft (19). During the rotation, the positioning column (15) will also rotate back and forth. Since the surfaces of the front sole pressure plate (2) and the rear sole pressure plate (3) are also subjected to pressure, the compression springs (17) on both sides will be squeezed, thereby driving the positioning column (15) to move downward, so that the electrode head (20) on the surface of the positioning column (15) and the electrode plate (16) contact each other. , and leave a position on the surface of the electrode plate (16). The conductive plate and the electrode head (20) can contact for 2 seconds to record the position left. The conductive seat (11) can send the position where the electrode plate (16) is conductive to the valve (30). At this time, the valve (30) controls the water valve to open according to the conductive position of the electrode plate (16) and the non-conductive position surrounded by the center of the conductive position corresponding to it. Since the patient will feel pain at the position where the disease is located, the patient can apply force to the position around the disease to press the forefoot pressure plate (2) or the rear foot pressure plate (3). The center of the pressed parts is not pressed, which is the part where the disease cannot apply force. By controlling the valve (30) in this area to open, the water pump (27) can control the water flow from the inside of the water pipe (31). When the inlet and outlet valves (30) and the water pump (27) pump water back and forth, the bag (23) will also swell or deflate, making the massage more gentle. At the same time, because the water in the transfer block (28) is heated and then enters the bag (23) through the water conduit (31), the patient will feel warm and more comfortable during the massage. It can also play a role in activating blood circulation and is beneficial to the patient's recovery. The conductive connecting bolt (26) can make the inside of the bags (23) in the same group conduct to each other, so that a single bag (23) will not swell or deflate to stimulate the diseased part. At the same time, the non-conductive connecting bolt (25) can prevent the water flow from being transmitted to the inside of all bags (23), so that the rehabilitation massage can be more targeted.The patient can be massaged while lying on the bed or resting, which is convenient to operate. At the same time, after the patient completes a massage cycle, the disposable gasket (29) is removed from the surface of the engaging groove (4), which is convenient for the next patient to use, and is clean and hygienic.
