[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0032] The embodiment of the present invention provides a walking aid for cardiothoracic surgery rehabilitation nursing. It includes an adjustment component 1, exemplarily, as Figure 1 As shown, a heart rate monitoring component 2 is installed on the top of the adjustment component 1, and two groups of walker components 3 are symmetrically sleeved on the bottom of the adjustment component 1. A group of hand limit components 4 are installed on the outer wall of each group of the walker components 3, a group of rebound components 5 are installed at one end of each group of the walker components 3, and a group of adsorption protection components 6 are installed at the other end of each group of the walker components 3.

[0033] For example, Figure 2As shown, the adjusting assembly 1 includes a fixed plate 101, a sliding cavity 103 is opened at the bottom of the fixed plate 101, two groups of threaded rods 102 are rotatably connected in the sliding cavity 103, and a partition block is connected between the two groups of threaded rods 102, one end of one group of threaded rods 102 away from the partition block is rotatably connected to the inner wall of one side of the fixed plate 101, and a first motor 106 is installed on the inner wall of one side of the fixed plate 101, and the output end of the first motor 106 is transmission connected to one group of threaded rods 102, the thread directions of the two groups of threaded rods 102 are opposite, and the central axes of the two groups of threaded rods 102 are located on the same straight line, each group of threaded rods 102 is threadedly connected to a group of sliding blocks 104, each group of sliding blocks 104 is slidably connected in the sliding cavity 103, and a group of sleeve rings 105 are installed at the bottom of each group of sliding blocks 104.

[0034] When the positions of the two groups of support tubes 301 need to be adjusted, the first motor 106 is started to drive the threaded rod 102 to rotate, and the threaded rod 102 drives the two groups of sliding blocks 104 to slide in the sliding cavity 103, thereby driving the two groups of sleeve rings 105 to move, and then driving the two groups of support tubes 301 to adjust their positions.

[0035] For example, Figure 3 As shown, the heart rate monitoring component 2 includes a connecting plate 201, the bottom of the connecting plate 201 is installed on the fixed plate 101, and a plurality of groups of movable rings 202 are evenly spaced on one side wall of the connecting plate 201. A rotating rod 203 is rotatably connected inside the movable ring 202, and a plurality of groups of fixed rings 204 are fixedly sleeved on the outer wall of the rotating rod 203. A display screen structure 206 is installed on the outer wall of the fixed ring 204. A second motor 205 is installed on one side wall of the connecting plate 201 close to the fixed ring 204, and the output end of the second motor 205 is transmission-connected to the rotating rod 203. A connector structure 207 is electrically connected to the outer wall of the display screen structure 206, and the other end of the connector structure 207 is electrically connected to the heart rate monitoring structure 208.

[0036] Before the walker for cardiothoracic surgery rehabilitation care is used, the heart rate monitoring structure 208 is first worn on the rehabilitation person, and the heart rate data is monitored through the display screen structure 206 to observe the wearer's situation during the rehabilitation process. In order to improve the viewing effect of the display screen structure 206, the second motor 205 is started to drive the rotating rod 203 to rotate. The rotating rod 203 drives the fixed ring 204 to rotate during the rotation process. Since the fixed ring 204 is in a connected state with the display screen structure 206, the display screen structure 206 is driven to rotate during the rotation of the rotating rod 203, thereby improving the heart rate monitoring observation effect while reducing the limitations of the patient's viewing angle.

[0037] For example, Figure 4 As shown, the walker assembly 3 includes support tubes 301, the outer walls of each group of the support tubes 301 are fixedly sleeved on the inner wall of the sleeve ring 105, and a group of handlebars 302 are sleeved on the outer walls of each group of the support tubes 301. Two groups of electric push rods 303 are symmetrically arranged at both ends of each group of the support tubes 301, and a group of fixing columns 304 are installed on the output end of each group of the electric push rods 303.

[0038] For example, Figure 5 As shown, the hand limiting assembly 4 includes a support plate 401, the top of each group of the support plates 401 is installed on the outer wall of the handle armrest 302, and a group of rectangular plates 403 are installed on the bottom of one side wall of each group of the support plates 401. A group of slides 402 are opened on the side wall of each group of the support plates 401 close to the rectangular plates 403, and a group of compression springs 404 are installed at the top center of each group of the rectangular plates 403. A group of elastic plastic plates 407 are installed at the other end of each group of the compression springs 404, and one end of each group of the elastic plastic plates 407 is slidably connected in the slide 402, and a group of first sleeve tubes 405 are installed on the top of each group of the rectangular plates 403, and a group of first sliding rods 406 are slidably connected on the inner wall of each group of the first sleeve tubes 405, and the top of each group of the first sliding rods 406 is installed on the bottom of the elastic plastic plate 407.

[0039] Then the elastic molding plate 407 is pushed to slide downward in the slide 402, and the compression spring 404 is squeezed. In the process, the first sliding rod 406 is driven to slide in the first sleeve 405 to prevent the compression spring 404 from shifting. When the rehabilitation personnel places their palms on the grip armrest 302, the pressing control of the elastic molding plate 407 is released. Then the compression spring 404 starts to rebound after sensing the disappearance of the pressure. During the rebound process, the palm of the rehabilitation personnel is limited and protected, which reduces the limitation of the limit and improves the protection effect for the rehabilitation personnel.

[0040] For example, Figure 6 As shown, the rebound assembly 5 includes a fixed disc 501, the top of each group of the fixed discs 501 is installed on the bottom of one group of the fixed columns 304, the bottom of each group of the fixed discs 501 is installed with a group of second sliding rods 502, the outer wall of each group of the second sliding rods 502 is slidably sleeved with a group of second sleeve tubes 503, the bottom of each group of the second sleeve tubes 503 is installed with a group of anti-slip bases 504, the outer wall of each group of the second sleeve tubes 503 is sleeved with a group of limiting rings 505, the top of each group of the limiting rings 505 is symmetrically provided with two groups of tension springs 506, and the other end of each group of the tension springs 506 is installed on the bottom of the fixed disc 501.

[0041] In order to improve the use effect of the walker, the electric push rod 303 is first started to drive the support tube 301 to adjust the height. Then, during the movement of the patient, the supporting force begins to act on the fixed disc 501. When the fixed disc 501 feels the pressure, it drives the second sliding rod 502 to slide in the second sleeve 503. During its sliding process, it drives the tension spring 506 to start pressing down, and the anti-slip base 504 prevents side slipping during use. Then, during the lifting process of the walker, the pressure disappears. When the tension spring 506 feels the pressure disappears, it starts to rebound. During its rebound process, it plays a role of counter-supporting the support tube, thereby reducing the labor intensity of moving the walker.

[0042] For example, Figure 7 As shown, the adsorption protection assembly 6 includes a third sliding rod 601, the top of each group of the third sliding rods 601 is installed on the bottom of another group of the fixed columns 304, and a group of third sleeve tubes 602 are slidably sleeved on the outer wall of each group of the third sliding rods 601, and a group of pressure sensors 603 are installed on the bottom of each group of the third sleeve tubes 602, and a group of mounting plates 604 are installed on the bottom of each group of the pressure sensors 603. The output end of each group of the pressure sensors 603 is located directly below the third sliding rod 601, and two groups of vacuum tubes 605 are symmetrically fixed on each group of the mounting plates 604. The top of each group of the vacuum tubes 605 is a closed structure, and the bottom of each group of the vacuum tubes 605 is connected to a group of vacuum suction cups 606, and a group of vacuum pumps 607 are installed on the outer wall of each group of the vacuum tubes 605.

[0043] During the movement of the patient, a supporting force will also act on the third sliding rod 601. The third sliding rod 601 begins to squeeze the pressure sensor 603 during the sliding process in the third sleeve 602. When the pressure sensor 603 senses the pressure, it sends instructions to the two sets of vacuum pumps 607. The two sets of vacuum pumps 607 evacuate the air in the two sets of vacuum tubes 605, so that a negative pressure state is formed in the vacuum tubes 605, and then the vacuum suction cup 606 is tightly fitted to the contact surface, and the problem of the walker being unable to support due to physical exhaustion in subsequent rehabilitation care is prevented, thereby improving the support effect of the walker while improving the safety effect of rehabilitation care.

[0044] During the movement of the patient, the supporting force is applied to the third sliding rod 601. The third sliding rod 601 begins to squeeze the pressure sensor 603 during the sliding process in the third sleeve 602. When the pressure sensor 603 senses the pressure, it sends instructions to the two sets of vacuum pumps 607. The two sets of vacuum pumps 607 evacuate the air in the two sets of vacuum tubes 605, so that a negative pressure state is formed in the vacuum tubes 605. Subsequently, the vacuum suction cup 606 is tightly fitted to the contact surface, and the problem of the walker being unable to support due to physical exhaustion in subsequent rehabilitation care is prevented, thereby improving the support effect of the walker while improving the safety effect of rehabilitation care.

[0045] The electric push rod 303 is started to drive the support tube 301 to adjust the height. Then, during the movement of the patient, the supporting force begins to act on the fixed disc 501. When the fixed disc 501 feels the pressure, it drives the second sliding rod 502 to slide in the second sleeve 503. During the sliding process, the tension spring 506 starts to press down, and the anti-slip base 504 prevents side slipping during use. Then, during the lifting process of the walker, the pressure disappears. When the tension spring 506 feels the pressure disappears, it starts to rebound. During the rebound process, it plays a role of counter-supporting the support tube, thereby reducing the labor intensity of moving the walker.

[0046] The heart rate monitoring structure 208 is worn on the rehabilitation person, and the heart rate data is monitored through the display screen structure 206 to observe the wearer's situation during the rehabilitation process. In order to improve the viewing effect of the display screen structure 206, the second motor 205 is started to drive the rotating rod 203 to rotate. The rotating rod 203 drives the fixed ring 204 to rotate during the rotation process. Since the fixed ring 204 is in a connected state with the display screen structure 206, the display screen structure 206 is driven to rotate during the rotation of the rotating rod 203, thereby improving the heart rate monitoring observation effect while reducing the limitations of the patient's viewing angle.

[0047] The elastic molding plate 407 is pushed to slide downward in the slide 402, and the compression spring 404 is squeezed. In the process, the first sliding rod 406 is driven to slide in the first sleeve 405 to prevent the compression spring 404 from shifting. When the rehabilitation personnel places their palms on the grip armrest 302, the pressing control of the elastic molding plate 407 is released. Then, the compression spring 404 starts to rebound after sensing the disappearance of the pressure. During the rebound process, the palm of the rehabilitation personnel is limited and protected, which reduces the limitation of the limit and improves the protection effect for the rehabilitation personnel.
