Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a walking aid for cardiovascular nursing patients. Background Technology

[0002] Cardiovascular rehabilitation is a comprehensive process involving multiple aspects such as drug therapy, exercise therapy, diet therapy, and psychotherapy. Among them, exercise therapy is the core of cardiac rehabilitation. Appropriate intensity exercise can significantly improve patients' exercise endurance, symptoms, and cardiopulmonary function. Patients need to use assistive walking devices during exercise.

[0003] The existing utility model with authorization announcement number CN218961228U discloses an auxiliary walking device, including a main shaft and a movable frame disposed on the outer walls at both ends of the main shaft. The bottom two outer walls of the movable frame are rotatably connected to a rotating disk through bearings, and the bottom outer walls of the rotating disks are fixedly installed with casters. The top outer walls on both sides of the movable frame are provided with vertical cylinders, and a connecting rod is provided between the top outer walls of the vertical cylinders.

[0004] The above technical solution allows for easy transfer of the device, and because the main shaft and the moving frame are square in shape, they provide sufficient support. Users can hold onto the connecting rods for support and movement, offering strong protection. However, the above technical solution lacks the ability to adjust the distance of the handrail, making it impossible to adjust according to different patients' usage habits. This reduces the applicability of the walking aid and fails to provide a stable resting environment for patients. When patients need to rest after walking for a short period, they need to find a place to rest on their own, reducing the effectiveness of the walking aid.

[0005] Therefore, those skilled in the art have provided a rehabilitation walking aid for cardiovascular patients to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a rehabilitation walking aid for cardiovascular patients, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A walking aid for cardiovascular care patients includes a counterweight frame, the counterweight frame having an auxiliary mechanism inside;

[0009] The auxiliary mechanism includes two connecting blocks, each of which is slidably connected to the inside of the counterweight frame. Two electric telescopic rods are fixedly connected to the inner wall of the counterweight frame, with the telescopic end of each rod fixedly connected to the upper surface of the connecting block. Two casters are fixedly connected to the bottom surface of each connecting block. A transmission rod is rotatably connected inside the counterweight frame, and a seat is fixedly connected to the outer surface of the transmission rod. A limit rod is slidably connected inside the counterweight frame, with its bottom end extending into the seat. A lifting block is slidably connected inside the counterweight frame, and two auxiliary blocks are slidably connected inside the lifting block. A handrail is fixedly connected to the upper surface of each auxiliary block. Two sets of fixing holes are provided on the upper surface of the lifting block, and two fixing bolts are provided above the lifting block. The bottom end of each fixing bolt passes through one of the fixing holes and is threadedly connected to an auxiliary block.

[0010] As a further improvement of this utility model: a stabilizing block is fixedly connected to the front of each of the connecting blocks, and each of the stabilizing blocks is slidably connected to the inside of the counterweight frame.

[0011] As a further improvement of this utility model: an auxiliary bearing is sleeved on the outer surface of the transmission rod, and the auxiliary bearing is embedded in the interior of the counterweight frame.

[0012] As a further improvement of this utility model: a push handle is fixedly connected to the top of the limiting rod, and the push handle is slidably connected to the inside of the counterweight frame.

[0013] As a further improvement of this utility model: a return spring is provided on the outer surface of the limiting rod, the bottom end of the return spring is fixedly connected to the inner wall of the limiting rod, and the top end of the return spring is fixedly connected to the inner wall of the counterweight frame.

[0014] As a further improvement of this utility model: the lifting block has multiple equidistant positioning holes inside, and the counterweight frame is internally threaded with positioning bolts, with one end of the positioning bolt near the counterweight frame extending into the interior of one of the positioning holes.

[0015] As a further improvement of this utility model: two reinforcing rings are fixedly connected to the outer surface of each handrail, and the bottom end of each reinforcing ring is fixedly connected to the upper surface of the auxiliary block.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model, by comprising a counterweight frame, connecting block, electric telescopic rod, casters, transmission rod, seat, limiting rod, lifting block, auxiliary block, handrail, fixing holes, and fixing bolts, allows the seat to be released from its limiting relationship by pulling the limiting rod, thereby enabling the seat to rotate with the transmission rod and be supported by the counterweight frame, thus providing a resting position for the patient. The electric telescopic rod drives the connecting block and casters to retract into the counterweight frame, preventing the counterweight frame from moving during rest and ensuring stability. By rotating the fixing bolts, the counterweight is moved out of the fixing holes and auxiliary blocks, and the two auxiliary blocks are manually adjusted within the lifting block. Finally, the auxiliary blocks are locked with the fixing bolts, thus enabling the handrail distance to be adjusted according to different patient usage habits. This improves the applicability of the assistive walking device and provides a stable resting environment for the patient. When the patient needs to rest after short periods of walking, they do not need to search for a place to rest, thereby enhancing the effectiveness of the assistive walking device.

[0023] Please see Figure 1-4 A walking aid for cardiovascular care patients includes a counterweight frame 1, and an auxiliary mechanism 2 is provided inside the counterweight frame 1.

[0024] The auxiliary mechanism 2 includes two connecting blocks 201, each of which is slidably connected to the inside of the counterweight frame 1. Each connecting block 201 has a stabilizing block 3 fixedly connected to its front side. Each stabilizing block 3 is slidably connected to the inside of the counterweight frame 1. The stabilizing block 3 can move simultaneously with the connecting block 201 and uses the friction generated by itself on the counterweight frame 1 during the movement to improve the stability of the connecting block 201 during movement and prevent jamming.

[0025] Two electric telescopic rods 202 are fixedly connected to the inner wall of the counterweight frame 1. The telescopic end of each electric telescopic rod 202 is fixedly connected to the upper surface of the connecting block 201. Two universal wheels 203 are fixedly connected to the bottom surface of each connecting block 201. A transmission rod 204 is rotatably connected inside the counterweight frame 1. An auxiliary bearing 4 is sleeved on the outer surface of the transmission rod 204 and embedded inside the counterweight frame 1. The auxiliary bearing 4 can reduce the friction generated by the transmission rod 204 when rotating, making the transmission rod 204 more sensitive when rotating. At the same time, it can also reduce the wear rate of the transmission rod 204 and increase the durability of the transmission rod 204.

[0026] A seat plate 205 is fixedly connected to the outer surface of the transmission rod 204. A limit rod 206 is slidably connected inside the counterweight frame 1. The bottom end of the limit rod 206 extends into the interior of the seat plate 205. A push handle 5 is fixedly connected to the top end of the limit rod 206. The push handle 5 is slidably connected inside the counterweight frame 1. The push handle 5 can provide a good force position for the limit rod 206, increasing the ease of pulling the limit rod 206 and improving the convenience of use.

[0027] A return spring 6 is provided on the outer surface of the limiting rod 206. The bottom end of the return spring 6 is fixedly connected to the inner wall of the limiting rod 206, and the top end of the return spring 6 is fixedly connected to the inner wall of the counterweight frame 1. The return spring 6 can continuously apply pressure to the limiting rod 206 by utilizing its own extension and contraction capacity, so that the limiting rod 206 has the ability to automatically reset, which increases the convenience when limiting and also improves the firmness of the limiting rod 206 when limiting.

[0028] The counterweight frame 1 has a sliding connection to a lifting block 207, and two auxiliary blocks 209 are slidably connected inside the lifting block 207. The lifting block 207 has multiple equidistantly arranged positioning holes 7 inside. The counterweight frame 1 has a threaded connection to a positioning bolt 8. One end of the positioning bolt 8 near the counterweight frame 1 extends into one of the positioning holes 7. By setting the positioning holes 7 and the positioning bolt 8, the current position of the lifting block 207 can be firmly and quickly fixed, preventing the lifting block 207 from moving during use and increasing the effectiveness of the device.

[0029] Each auxiliary block 209 has a handrail 210 fixedly connected to its upper surface. The upper surface of the lifting block 207 has two sets of fixing holes 212. Two fixing bolts 213 are provided on the top of the lifting block 207. The bottom end of each fixing bolt 213 passes through one of the fixing holes 212 and is threadedly connected to the auxiliary block 209. Each handrail 210 has two reinforcing rings 9 fixedly connected to its outer surface. The bottom end of each reinforcing ring 9 is fixedly connected to the upper surface of the auxiliary block 209. The reinforcing rings 9 can increase the fixed connection area between the handrail 210 and the auxiliary block 209, thereby making the connection between the two more secure and preventing the possibility of breakage at the connection after long-term use, thus increasing the robustness of the device.

[0030] The working principle of this utility model is as follows: In use, first connect the electric telescopic rod 202 to the power supply. When the device is needed, push the counterweight frame 1 through the handrail 210, allowing it to move using the casters 203. When adjusting the height of the handrail 210, rotate the positioning bolt 8 to move it out of the lifting block 207 and positioning hole 7. Then pull the lifting block 207 to the appropriate position and reinsert the positioning bolt 8 into one of the positioning holes 7 and the lifting block 207. When changing the distance between the two handrails 210, rotate the fixing bolt 213 to move it out of the auxiliary block 209 and fixing hole 212. Then push the auxiliary block 209 to move the handrail 210 to the appropriate position. Finally, insert the fixing bolt 213 into the appropriate fixing hole 212 and thread it into the auxiliary block 209, thus adjusting the position of the handrail 210 and effectively increasing the height for different people. To enhance user comfort, when a patient needs to rest after prolonged use, the electric telescopic rod 202 is activated, causing the connecting block 201 and casters 203 to rise and retract into the counterweight frame 1, bringing the counterweight frame 1 into contact with the ground and preventing it from moving. Then, the handle 5 is pushed upwards, causing the limiting rod 206 to retract into the counterweight frame 1, freeing the seat 205 from the limiting rod 206. The transmission rod 204 then rotates the seat 205 90 degrees, bringing it into contact with the counterweight frame 1 for support. The patient can then sit on the seat 205 to rest. The return spring 6 pushes the limiting rod 206 back to its original position, increasing the ease of retracting the seat 205 after rest. This effectively provides a stable resting space for the patient and improves the effectiveness of the cardiovascular nursing rehabilitation walking aid.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
