Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a postoperative rehabilitation and nursing device. Background Technology
[0002] Patients who have undergone cardiac surgery usually need rehabilitation training to gradually restore normal physical function and mobility. Due to their weakened state after surgery, patients are prone to problems such as instability and poor balance during the early rehabilitation process. This requires medical staff or family members to supervise them during rehabilitation training, which not only increases manpower consumption but also puts psychological pressure on patients and affects their enthusiasm for exercise. Therefore, we propose a postoperative rehabilitation nursing device. Utility Model Content
[0003] The purpose of this invention is to provide a postoperative rehabilitation and nursing device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a postoperative rehabilitation nursing device, comprising a frame, with casters fixedly connected to the lower front end of the frame, auxiliary wheels rotatably connected to both sides of the rear end of the frame, a chest strap provided in the middle of the frame, a sliding seat cushion provided below the chest strap, and a handle fixedly connected to the upper front end of the frame.
[0005] The sliding seat cushion has several support shafts inserted into its inner side, and rollers are connected to both ends of the support shafts. The frame and the inner side are provided with L-shaped grooves, and the rollers slide in the L-shaped grooves.
[0006] The auxiliary wheel is fixedly connected to a rotating shaft, which is rotatably connected to the frame. A centrifugal clamp is fixedly connected between the rotating shaft and the frame and the auxiliary wheel. An inner ratchet is provided on the outside of the centrifugal clamp on the frame.
[0007] The chest strap is fixedly connected to a pad, and sliders are fixedly connected to both sides of the pad. The surface of the chest strap is provided with corresponding Velcro.
[0008] The support shafts are rotatably connected to each other by connecting rods, and the sliding seat cushion is rotatably connected to the bottom end of the chest strap through the support shaft at the top and the connecting rods.
[0009] The centrifuge clamp includes a centrifuge block rotatably connected to the surface of the rotating shaft, and a spring is fixedly connected between the end of the centrifuge block away from the connection point and the rotating shaft.
[0010] The grip is designed to be vertically upward, and the surface of the grip has anti-slip texture and a wavy design at the front end.
[0011] This utility model has at least the following beneficial effects:
[0012] In use, this invention utilizes a centrifugal clip mounted on the auxiliary wheel and an inner ratchet to form an automatic locking mechanism. When the patient's walking speed exceeds a safe threshold, the centrifugal block is thrown out under centrifugal force and engages with the inner ratchet, locking the auxiliary wheel and preventing the patient from losing control or falling due to excessive speed. The chest strap and sliding cushion provide support when the patient is standing, forming an I-shape. When the patient sits down or falls due to instability, the chest strap drives the sliding cushion to slide along an L-shaped groove, transforming the cushion into an L-shape to form a seat. This allows the device to dynamically adapt to changes in the patient's posture, preventing accidental falls and providing necessary rest support, effectively reducing the risk of accidental injury.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1
[0023] Please see Figures 1 to 6 This utility model provides a technical solution: a postoperative rehabilitation nursing device, including a frame 1, which is the main structure of the entire rehabilitation device, bearing all components and providing overall frame support. The U-shaped design allows the patient to stand in the middle of the device, providing a safe support environment. A caster wheel 2 is fixedly connected to the lower front end of the frame 1, providing 360-degree flexible turning. Auxiliary wheels 3 are rotatably connected to both sides of the rear end of the frame 1, providing straight-line stability during walking. The larger fixed wheels enhance the overall stability of the cart, especially during straight-line walking, preventing tipping or deviation from the track. A chest strap 4 is provided in the middle of the frame 1, which is fixed to the patient's chest to ensure the patient maintains an upright posture during the process of being pushed. The chest strap 4 is fixedly connected to a pad 41. The chest strap 4 and the pad 41 can provide effective support for the patient and prevent the patient from falling due to instability. The Velcro 43 on its surface is designed for easy and quick adjustment and fixation to adapt to patients of different body types. Slider 42 is fixedly connected to both sides of the pad 41. A sliding seat 5 is provided below the chest strap 4. Several support shafts 51 are inserted into the inner side of the sliding seat 5. Rollers 52 are connected to both ends of the support shafts 51. The frame 1 has an L-shaped groove 11 on the inner side. The rollers 52 slide in the L-shaped groove 11. The support shafts 51 are rotatably connected to each other by a connecting rod 511. The sliding seat 5 is rotatably connected to the bottom end of the chest strap 4 through the support shafts 51 at the top and the connecting rods 511. The sliding seat 5 slides in the L-shaped groove 11 through the support shafts 51 and the rollers 52 on the inner side. When the patient is standing, the chest strap 4 and the sliding seat cushion remain in an I-shape. When the patient's body sinks, the chest strap 4 will drive the sliding seat cushion 5 to slide along the L-shaped groove 11, eventually turning the sliding seat cushion into an L-shape to form a seat and provide support. A handle 6 is fixedly connected to the upper front of the frame 1, allowing the patient to hold and control the direction of the trolley. When in use, the patient stands in the middle of the frame, wraps the chest strap 4 around the chest and secures it with Velcro 43, holds the handle 6 and slowly pushes the trolley for walking training. The omnidirectional wheels 2 at the front provide flexible steering, while the auxiliary wheels 3 at the rear ensure straight-line stability. If the patient needs to rest or suddenly feels unwell, they can gradually lower their center of gravity. The chest strap 4 will drive the sliding seat cushion 5 to slide in the L-shaped groove 11 through the linkage 511. When the patient's body sinks, the sliding seat cushion 5 will turn into an L-shape to form a safe and stable seat, preventing the patient from falling directly to the ground. After use, the patient can slowly stand up, and the sliding seat cushion will return to its original position.
[0024] An auxiliary wheel 3 is fixedly connected to a rotating shaft 31. The rotating shaft 31 connects the auxiliary wheel 3 and the frame 1, allowing the auxiliary wheel 3 to rotate around its axis. A centrifugal locking element 32 is fixedly connected between the rotating shaft 31 and the frame 1. Through the cooperation of the rotating shaft 31 and the centrifugal locking element 32, the auxiliary wheel 3 can automatically lock when the speed is abnormal, enhancing the safety of the device. The centrifugal locking element 32 includes a centrifugal block 321 rotatably connected to the surface of the rotating shaft 31. A spring 322 is fixedly connected between the end of the centrifugal block 321 away from the connection point and the rotating shaft 31. An inner ratchet 12 is provided on the outside of the centrifugal locking element 32 on the frame 1. When the speed is slow, the centrifugal block 321 is controlled by the spring 322. 2. When pulled towards the rotating shaft 31, the centrifugal block 321 rotates within the inner ratchet 12. When the speed is too fast, the centrifugal block 321 is thrown out under the action of centrifugal force, thereby locking the inner ratchet 12 and preventing the rotating shaft 31 and the auxiliary wheel 3 from rotating, thus braking the device and ensuring a rapid response when the trolley speed exceeds the safe range, preventing the patient from accidentally slipping and enhancing safety. In use, when the patient's trolley speed exceeds the safe threshold, the centrifugal block 321 in the centrifugal clip 32 is thrown out and locked into the inner ratchet 12, automatically locking the auxiliary wheel 3 to prevent accidental slipping and falling. After the patient stabilizes, they can move backward to reset the centrifugal block 321, unlock the auxiliary wheel 3, and continue walking.
[0025] Example 2
[0026] Please see Figure 7 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the handle 6 is designed to be vertically upward. The surface of the handle 6 is provided with anti-slip texture 61 and the front end is designed with a wave shape. The vertical upward design makes it easy to hold, and the anti-slip texture 61 on the surface can increase friction, prevent the patient's hand from slipping, and ensure stable control. The wave shape design can fit the patient's hand better and improve the comfort of holding.
