Description

Technical Field

[0001] This invention relates to the field of physical therapy equipment technology, and in particular to a physical therapy device for the rehabilitation of elderly patients with cardiovascular and cerebrovascular diseases. Background Technology

[0002] Cardiovascular and cerebrovascular diseases refer to diseases of the heart and brain blood vessels. They are generally defined as ischemic and hemorrhagic diseases of the heart, brain and other tissues caused by various factors. Cardiovascular and cerebrovascular diseases are common diseases that seriously threaten human health, especially the health of the elderly. In order to improve the prognosis and quality of life, rehabilitation treatment is needed for patients. Currently, the main method of rehabilitation treatment is rehabilitation training, which improves cardiopulmonary endurance and function, enhances the heart's pumping function, and promotes blood circulation through aerobic exercise and other means. For example, a cardiovascular and cerebrovascular rehabilitation training device with publication number CN206482808U allows the patient to push and pull the handles with both hands when using the device. Then, the first link drives the second link to lift the leg support, so that both the hands and legs can move, promoting the patient's rehabilitation. However, cardiovascular and cerebrovascular diseases often result in many sequelae after recovery. Mild cases may present with limb paralysis or weakness and muscle weakness, while severe cases may result in complete paralysis. When using this device for rehabilitation training, patients may find it difficult to push the handles to achieve the desired exercise effect and require assistance from a specialist. Furthermore, paralyzed or hemiplegic patients may find it even more difficult to maintain a stable sitting posture due to muscle atrophy, thus making it impossible for them to achieve the desired rehabilitation training effect through this device. Summary of the Invention

[0003] The purpose of this invention is to provide a physical therapy device for the rehabilitation of elderly patients with cardiovascular and cerebrovascular diseases, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A physical therapy device for rehabilitation of elderly patients with cardiovascular and cerebrovascular diseases includes a bed, an electrocardiogram monitor is installed on one side of the bed, a mattress is placed on the top of the bed, the mattress includes a first support pad and a second support pad, the connection between the first support pad and the second support pad is hinged by a pivot, and a physical therapy component for assisting elderly patients in rehabilitation treatment is provided on the second support pad. The physical therapy component includes a first treatment component and two sets of second treatment components disposed on a second support pad. The first treatment component is located on the second support pad at one end near the first support pad, and the two sets of second treatment components are respectively located on the other end of the second support pad. The second support pad is also provided with a drive component and a lifting component for driving the physical therapy component to start, and the signal input terminal of the drive component is connected to an electrocardiogram monitor.

[0005] Furthermore, the first treatment component includes a fixing plate, which is fixedly connected to the second support pad. The top of the fixing plate is provided with a first airbag strap and a second airbag strap. One end of the first airbag strap and the second airbag strap are both fixed to the fixing plate. The other end of the first airbag strap and the second airbag strap are respectively provided with a hook and loop side and a loop side.

The ends of the first leg airbag belt and the second leg airbag belt away from the support plate are respectively provided with a hook and loop side and a loop and loop side. The other end of the top of the support plate is also fixedly connected to a third leg airbag belt and a fourth leg airbag belt. The ends of the third leg airbag belt and the fourth leg airbag belt away from the support plate are respectively provided with a hook and loop side and a loop and loop side.

[0007] Furthermore, each of the two sets of support plates is fixedly connected to a rotating shaft at one end near the fixed plate. The rotating shafts are located on both sides of the adjacent support plates, and both sets of support plates are rotatably connected to the second support pad through the adjacent rotating shafts.

[0008] Furthermore, the second support pad is also fixedly connected to an L-shaped fixing frame for supporting the drive assembly. The drive assembly includes a first piston cylinder, a second piston cylinder, and a third piston cylinder fixedly connected to the L-shaped fixing frame. A piston rod is slidably connected to each of the first, second, and third piston cylinders. A synchronous rack is fixedly connected to each piston rod. A return spring is sleeved on the arc of each piston rod, and one end of the return spring is fixed to the adjacent piston rod, while the other end is fixedly connected to the adjacent first, second, and third piston cylinders, respectively.

[0009] Furthermore, the output end of the first piston cylinder is connected to the first and second airbag straps on the fixed plate, the output end of the second piston cylinder is connected to the first and second leg airbag straps on the two sets of support plates, and the third piston cylinder is connected to the third and fourth leg airbag straps on the two sets of support plates.

[0010] Furthermore, the drive assembly also includes a drive motor fixedly connected to the second support pad. The output end of the drive motor is fixedly connected to a connecting rod. The end of the connecting rod away from the drive motor extends into the L-shaped fixing frame. The extended end of the connecting rod is fixed to the lifting assembly. Multiple sets of incomplete gears are fixedly connected to the connecting rod, and each set of incomplete gears meshes with an adjacent synchronous rack.

[0011] Furthermore, the lifting assembly includes a synchronizing plate, which is rotatably connected to one side of the L-shaped fixing frame.

A synchronization gear is rotatably connected above the second drive rack and meshes with the second drive rack. Synchronization rods are fixedly connected to both sides of the synchronization gear. The ends of the two synchronization rods away from the synchronization gear are rotatably connected to the inner walls of both sides of the second support pad. A driven gear is fixedly connected to each of the two synchronization rods. Both sets of support plates are provided with a first drive rack at the end away from the fixed plate, and the two sets of first drive racks are respectively hinged to the bottom of the adjacent support plates through a rotating shaft, and the two sets of first drive racks respectively mesh with the adjacent driven gear.

[0013] Compared with existing technologies, the above solution has the following advantages: 1. This invention features a user-friendly design and simple operation. Patients simply need to lie on the support pad and put on the airbag strap. The treatment process requires no complicated operations, reducing the patient's psychological burden and operational difficulty. Moreover, the device operates in sync with the patient's cardiac cycle, causing no additional physical discomfort and improving patient compliance. Furthermore, the device is integrated with the bed, allowing for effective rehabilitation treatment without the need for voluntary exertion. It can also provide good rehabilitation exercises for paralyzed or immobile patients, greatly improving the feasibility and operability of rehabilitation training, and is especially suitable for patients with weak physical strength.

[0014] 2. This invention greatly enhances rehabilitation effects by coordinating with the patient's cardiac cycle. During diastole, the drive motor starts, and through the meshing of incomplete gears and synchronous racks, the air bladders in the patient's calves, thighs, and buttocks are inflated in an orderly manner. This method of inflating from the distal to the proximal end of the limb can compress the blood vessels in the lower limbs and buttocks, driving blood back to the aorta, significantly increasing the aortic diastolic pressure and blood flow, thereby increasing the perfusion of the coronary arteries, cerebral arteries, etc. This is crucial for improving the blood supply to the myocardium, brain tissue, kidneys, and other vital organs of patients with cardiovascular and cerebrovascular diseases, effectively relieving symptoms such as myocardial ischemia and insufficient cerebral blood supply, and promoting the recovery of organ function.

[0015] 3. In this invention, after the end of the diastolic phase of the heart, the device automatically extracts the gas from the airbag, so that the airbag no longer compresses the blood vessels, ensuring that the blood pumped from the heart can flow smoothly to the lower limbs and maintaining normal blood circulation. At the same time, during the diastolic phase of the heart, the device also drives the support plate to rise through a series of mechanical structures such as the synchronization disc, push rod, and synchronization frame, so that the patient's lower limbs are slightly raised, further promoting blood return to the heart and helping to improve the overall function of the heart. During the systolic phase of the heart, the support plate falls, allowing blood to be pumped smoothly to the lower limbs, ensuring smooth blood circulation and avoiding blood circulation disorders caused by external force intervention.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] In the description of this invention, it should be understood that the terms "upper," "lower," "top surface," "bottom surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are only used to distinguish an entity or operation from another entity or operation, and do not require or imply any actual relationship, order, or relative importance between these entities or operations.

[0020] Example 1, referring to Figure 1-9A physical therapy device for rehabilitation of elderly patients with cardiovascular and cerebrovascular diseases includes a bed 1, an electrocardiogram monitor on one side of the bed 1, and a mattress 2 on the top of the bed 1. The mattress 2 includes a first support pad 21 and a second support pad 22. The connection between the first support pad 21 and the second support pad 22 is hinged by a pivot. The second support pad 22 is provided with a physical therapy component for assisting elderly patients in rehabilitation treatment. The physical therapy component includes a first treatment component 3 and two sets of second treatment components 4 disposed on the second support pad 22. The first treatment component 3 is located on the second support pad 22 at one end near the first support pad 21, and the two sets of second treatment components 4 are respectively located on the other end of the second support pad 22. The interior of the second support pad 22 is also provided with a drive component 5 and a lifting component 6 for driving the physical therapy component to start, and the signal input terminal of the drive component 5 is connected to the electrocardiogram monitor. Specifically, during use, the elderly patient is first laid flat on mattress 2. The first treatment component 3 and the second treatment component 4 are fixed to the patient's buttocks, thighs, and calves, respectively. An electrocardiogram (ECG) monitor is then connected to the patient. After connection, the ECG monitor is activated to monitor the patient's heart rate. Once the patient's heart rate stabilizes, the drive component 5 is energized, connecting its signal input to the ECG monitor. The drive component 5 and the lifting component 6 then drive the first treatment component 3 and the second treatment component 4 to activate in sync with the patient's cardiac cycle. During diastole, the first treatment component 3 and the second treatment component 4 inflate, promoting blood flow from the lower limbs back to the heart. During systole, the first treatment component 3 and the second treatment component 4 deflate, allowing blood to be pumped back to the lower limbs. Through inflation and deflation synchronized with the heart's systolic and diastolic cycles, the aortic diastolic pressure and blood flow are significantly increased, perfusion of the coronary arteries and cerebral arteries is enhanced, while simultaneously reducing cardiac load, improving cardiac function, and promoting vascular health.

[0021] In this embodiment, the first treatment component 3 includes a fixing plate 31, which is fixedly connected to the second support pad 22. A first airbag strap 32 and a second airbag strap 33 are provided on the top of the fixing plate 31. One end of each airbag strap 32 and airbag strap 33 is fixed to the fixing plate 31. The other ends of the airbag strap 32 and airbag strap 33 are respectively provided with a hook and loop side and a loop side. The air inlet ends of both the airbag strap 32 and airbag strap 33 are connected to the drive component 5. The second treatment component 4 includes a support plate 41, which is disposed in the second support pad 22. The top end of the support plate 41 near the fixing plate 31 is fixedly connected to a first leg support. The first leg airbag strap 42 and the second leg airbag strap 43 are respectively provided with a hook and loop fastener at the ends away from the support plate 41. The other end of the top of the support plate 41 is also fixedly connected to the third leg airbag strap 44 and the fourth leg airbag strap 45. The ends of the third leg airbag strap 44 and the fourth leg airbag strap 45 away from the support plate 41 are respectively provided with a hook and loop fastener at the ends. The ends of the two sets of support plates 41 near the fixed plate 31 are fixedly connected to the rotating shaft 47. The rotating shaft 47 is located on both sides of the adjacent support plates 41. The two sets of support plates 41 are rotatably connected to the second support pad 22 through the adjacent rotating shaft 47. Specifically, in use, the patient is first laid on the first support pad 21 and the second support pad 22, with the patient's buttocks on the fixation plate 31 and the patient's lower limbs on the two sets of support plates 41. The first airbag strap 32 and the second airbag strap 33 are put on the patient's buttocks, and the first leg airbag strap 42 and the second leg airbag strap 43 on the two sets of support plates 41 are put on the patient's thighs. The third leg airbag strap 44 and the fourth leg airbag strap 45 are put on the patient's calves. After fixing, the electrocardiogram monitor is turned on to monitor the patient's heart rate. When the patient's heart rate tends to be stable, the drive component 5 is energized. The drive component 5 sequentially drives the third leg airbag strap 44 and the fourth leg airbag strap 45, the first leg airbag strap 42 and the second leg airbag strap 43, and the first airbag strap 32 and the second airbag strap 33 to inflate, compressing the blood vessels of the lower limbs and buttocks from the distal end, driving the blood back to the aorta.

[0022] In this embodiment, an L-shaped fixing frame 23 for supporting the drive assembly 5 is also fixedly connected to the second support pad 22. The drive assembly 5 includes a first piston cylinder 51, a second piston cylinder 52, and a third piston cylinder 53 fixedly connected to the L-shaped fixing frame 23. A piston rod 54 is slidably connected to each of the first piston cylinder 51, the second piston cylinder 52, and the third piston cylinder 53. A synchronous rack 55 is fixedly connected to each piston rod 54. A return spring is sleeved on the arc of each piston rod 54, and one end of the return spring is fixed to the adjacent piston rod 54, while the other end is fixedly connected to the adjacent first piston cylinder 51, second piston cylinder 52, and third piston cylinder 53, respectively. The output end of the first piston cylinder 51 is connected to the first gas cylinder on the fixing plate 31. The second airbag belt 32 is connected to the second airbag belt 33. The output end of the second piston cylinder 52 is connected to the first leg airbag belt 42 and the second leg airbag belt 43 on the two sets of support plates 41. The third piston cylinder 53 is connected to the third leg airbag belt 44 and the fourth leg airbag belt 45 on the two sets of support plates 41. The drive assembly 5 also includes a drive motor 56 fixedly connected to the second support pad 22. The output end of the drive motor 56 is fixedly connected to a connecting rod 57. The end of the connecting rod 57 away from the drive motor 56 extends into the L-shaped fixing frame 23. The extended end of the connecting rod 57 is fixedly connected to the lifting assembly 6. Multiple sets of incomplete gears 58 are fixedly connected to the connecting rod 57. Each set of incomplete gears 58 meshes with the adjacent synchronous rack 55. Specifically, after the drive assembly 5 is powered on, the drive motor 56 starts following the patient's cardiac cycle. When the heart is in diastole, the drive motor 56 starts and drives the connecting rod 57 to rotate. Multiple sets of incomplete gears 58 on the connecting rod 57 rotate simultaneously. The incomplete gear 58 closest to the third piston cylinder 53 first meshes with the synchronous rack 55, and drives the synchronous rack 55 to move towards the third piston cylinder 53. This causes the synchronous rack 55 to drive the piston rod 54 to slide inside the third piston cylinder 53, pumping the gas in the third piston cylinder 53 into the third leg airbag belt 44 and the fourth leg airbag belt 45, inflating the third leg airbag belt 44 and the fourth leg airbag belt 45 to inflate the lower legs. The blood vessels in the thigh are compressed. When the incomplete gear 58 near the third piston cylinder 53 meshes with the synchronous rack 55, the incomplete gear 58 near the second piston cylinder 52 also begins to mesh with the synchronous rack 55 on the second piston cylinder 52, and drives the piston rod 54 in the second piston cylinder 52 to move, so that the gas pump in the second piston cylinder 52 pumps into the first leg airbag belt 42 and the second leg airbag belt 43 to compress the blood vessels in the thigh. Then the incomplete gear 58 at the first piston cylinder 51 meshes with the synchronous rack 55 on the first piston cylinder 51, so that the gas pump in the first piston cylinder 51 pumps into the first airbag belt 32 and the second airbag belt 33 to compress the blood vessels in the buttocks. After the diastolic phase of the heart ends, multiple sets of incomplete gears 58 rotate until they disengage from the adjacent synchronous racks 55. At this time, under the action of the return spring, multiple sets of piston rods 54 move outward, causing the first piston cylinder 51, the second piston cylinder 52, and the third piston cylinder 53 to extract the gas from the third leg airbag belt 44, the fourth leg airbag belt 45, the first leg airbag belt 42, the second leg airbag belt 43, the first airbag belt 32, and the second airbag belt 33, respectively. This allows the deflation of the airbags to no longer compress the blood vessels, and the blood pumped from the heart can flow smoothly to the lower limbs.

[0023] In this embodiment, the lifting assembly 6 includes a synchronization disc 61, which is rotatably connected to one side of the L-shaped fixing frame 23. The side of the synchronization disc 61 closest to the L-shaped fixing frame 23 is fixed to the connecting rod 57 in the L-shaped fixing frame 23 via a connecting shaft. A push rod 62 is fixedly connected to the side of the synchronization disc 61 away from the L-shaped fixing frame 23, and the push rod 62 is located at an eccentric position on the synchronization disc 61. A synchronization frame 63 is sleeved on the push rod 62. A drive rod 64 is fixedly connected to the side of the synchronization frame 63 facing the second treatment assembly 4. Two sets of limiting rods 65 are also fixedly connected to the synchronization frame 63. The synchronization frame 63 is slidably connected to the inner wall of the second support pad 22 via the two sets of limiting rods 65. The end of the drive rod 64 away from the synchronization frame 63 is fixedly connected to... A second drive rack 66 is slidably connected to the second support pad 22. A synchronous gear 67 is rotatably connected above the second drive rack 66 and meshes with the second drive rack 66. Synchronous rods 68 are fixedly connected to both sides of the synchronous gear 67. The ends of the two synchronous rods 68 away from the synchronous gear 67 are rotatably connected to the inner walls of both sides of the second support pad 22. Driven gears 69 are fixedly connected to the two synchronous rods 68. A first drive rack 46 is provided at the end of the two sets of support plates 41 away from the fixed plate 31. The two sets of first drive racks 46 are respectively hinged to the bottom of the adjacent support plates 41 through a rotating shaft. The two sets of first drive racks 46 mesh with the adjacent driven gears 69 respectively. Specifically, when the drive motor 56 drives multiple sets of incomplete gears 58 to rotate, the connecting rod 57 simultaneously drives the synchronous disk 61 to rotate. The rotation of the synchronous disk 61 drives the push rod 62 to move simultaneously, causing the push rod 62 to push the synchronous frame 63 to move left and right. When the heart is in diastole and the synchronous rack 55 pumps gas into the air bag, the synchronous disk 61 simultaneously drives the push rod 62 to move, causing the push rod 62 to pull the synchronous frame 63 towards the first treatment component 3. The synchronous frame 63 remains horizontal under the action of the limiting rod 65. When the synchronous frame 63 moves... At the same time, the synchronization frame 63 pulls the drive rod 64 and the second drive rack 66 to move, so that the second drive rack 66 drives the synchronization gear 67 to rotate. The synchronization gear 67 drives the two driven gears 69 to rotate through the two synchronization rods 68. When the two driven gears 69 rotate, they drive the adjacent first drive racks 46 to move upward, so that the two first drive racks 46 respectively lift one end of the two support plates 41. By driving the support plates 41 to lift during the diastolic phase of the heart, the support plates 41 can lift the patient's lower limbs slightly, further promoting blood return to the heart. When the heart is in systole, the synchronization disc 61 pushes the synchronization frame 63 and the drive rod 64 away from the first treatment component 3 via the push rod 62, causing the second drive rack 66 to drive the synchronization gear 67 to rotate in the opposite direction. The two driven gears 69 rotate in the opposite direction, causing the support plate 41 to fall. The support plate 41 drives the patient's lower limbs to fall, so that blood can be smoothly pumped to the lower limbs during systole.

[0024] Working principle of the invention: In use, first, have the patient lie on the first support pad 21 and the second support pad 22, with the patient's buttocks on the fixation plate 31 and the patient's lower limbs on the two sets of support plates 41. Put the first airbag strap 32 and the second airbag strap 33 on the patient's buttocks, and put the first leg airbag strap 42, the second leg airbag strap 43, the third leg airbag strap 44 and the fourth leg airbag strap 45 on the two sets of support plates 41 on the patient's lower limbs respectively. After fixing, turn on the electrocardiogram monitor to monitor the patient's heart rate. When the patient's heart rate tends to be stable, turn on the drive component 5. After the drive assembly 5 is powered on, the drive motor 56 starts following the patient's cardiac cycle. When the heart is in diastole, the drive motor 56 starts and drives the connecting rod 57 to rotate. Multiple sets of incomplete gears 58 on the connecting rod 57 rotate simultaneously. The multiple sets of incomplete gears 58 mesh with the adjacent synchronous rack 55 in sequence, driving the first piston cylinder 51, the second piston cylinder 52 and the third piston cylinder 53 to inflate the air bladders in the patient's lower leg, thigh and buttock. The air bladders inflate from the distal end of the limb to the proximal end in sequence, compressing the blood vessels in the lower limb and buttock, driving the blood back to the aorta, significantly increasing the aortic diastolic pressure and blood flow, and increasing the perfusion of the coronary arteries, cerebral arteries and renal arteries. After the diastolic phase of the heart ends, multiple sets of incomplete gears 58 rotate until they disengage from the adjacent synchronous racks 55. At this time, under the action of the return spring, multiple sets of piston rods 54 move outward, causing the first piston cylinder 51, the second piston cylinder 52, and the third piston cylinder 53 to extract the gas from the third leg airbag belt 44, the fourth leg airbag belt 45, the first leg airbag belt 42, the second leg airbag belt 43, the first airbag belt 32, and the second airbag belt 33, respectively. This allows the deflation of the airbags to no longer compress the blood vessels, and the blood pumped from the heart can flow smoothly to the lower limbs. When the heart is in diastole and the synchronous rack 55 pumps gas into the air bag, the connecting rod 57 simultaneously drives the synchronous disk 61 to rotate, causing the push rod 62 to pull the synchronous frame 63 to move closer to the first treatment component 3. The synchronous frame 63 simultaneously pulls the drive rod 64 and the second drive rack 66 to move, causing the second drive rack 66 to drive the synchronous gear 67 to rotate. The synchronous gear 67 drives the two driven gears 69 to rotate through the two synchronous rods 68. When the two driven gears 69 rotate, they drive the adjacent first drive racks 46 to move upward, so that the two first drive racks 46 respectively lift one end of the two support plates 41. By lifting the support plates 41 during the heart's diastole, the support plates 41 can slightly lift the patient's lower limbs, further promoting blood return to the heart. When the heart is in systole, the synchronization disc 61 pushes the synchronization frame 63 and the drive rod 64 away from the first treatment component 3 via the push rod 62, causing the second drive rack 66 to drive the synchronization gear 67 to rotate in the opposite direction. The two driven gears 69 rotate in the opposite direction, causing the support plate 41 to fall. The support plate 41 drives the patient's lower limbs to fall, so that blood can be smoothly pumped to the lower limbs during systole.

[0025] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
