Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to an auxiliary turning device for bedridden patients. Background Technology

[0002] In clinical and home care settings, the care of long-term bedridden patients faces numerous practical needs, among which regular changes in patient position are a crucial aspect of maintaining their health. These patients, due to illness, injury, or post-operative recovery, often lack the ability to change position independently. Maintaining a fixed position can easily lead to complications such as pressure sores, lung infections, and muscle atrophy, negatively impacting their recovery process and quality of life. Currently, turning bedridden patients typically requires manual assistance from caregivers. This process must consider factors such as the patient's physical condition, weight, and bedridden posture, using standardized techniques to help the patient achieve positional changes such as turning to the side or sitting up. This maintains smooth blood circulation, reduces pressure on local tissues, and facilitates routine cleaning, monitoring, and treatment procedures for caregivers. With the continuous improvement of medical and nursing standards, higher requirements have been placed on the safety, comfort, and convenience of bedridden patient care. Developing specialized devices that can assist in patient turning operations has become an important direction for meeting clinical nursing needs and improving nursing efficiency. Related technological research is also gradually unfolding around how to better adapt to different bedridden scenarios, conform to ergonomic design, and ensure operational stability.

[0003] For example, Chinese utility model patent (CN220714206U) discloses a patient turning assistance device, which solves the following problems: Existing patient turning assistance devices require the participation and operation of medical staff, which may lead to the inability to provide turning care to all patients in a timely manner when there is a shortage of manpower or nursing staff are busy. In addition, medical staff need to learn how to use the device correctly to avoid misoperation or causing other problems, which increases the cost and workload of training and education.

[0004] The device includes a bed board with a partition fixedly connected to its top surface. Turning panels are located on both sides of the partition and are rotatably connected to the partition via hinges. A self-turning mechanism is fixedly connected to the bottom of the turning panels. Support legs are fixedly connected to the bottom corners of the bed board, and a fixing plate is fixedly connected between the support legs. Several control buttons are symmetrically arranged on the surface of the bed board. This invention, through the self-turning mechanism, allows the patient to turn over by pressing a control button, which activates a drive motor, causing the turning panels to rotate and apply a pushing force to the patient's back on the bed board. This allows the patient to turn over according to their own situation and needs, without being restricted by the schedules of medical staff.

[0005] When using the above technology, the following technical problems were found in the existing technology: the device does not have a suitable rotation speed adjustment structure, which cannot adapt to the physical tolerance of different patients, easily causing patient discomfort or increasing the risk of pressure sores. It is also difficult for caregivers to adjust the rotation rhythm according to the patient's real-time condition, which can easily lead to patient resistance. At the same time, it has great limitations in dealing with different nursing scenarios, and its overall practicality is significantly reduced. Therefore, we designed a bedridden patient auxiliary rotation device to provide another technical solution to the above technical problems. Utility Model Content

[0036] This utility model provides an auxiliary turning device for bedridden patients. Through the design of its rotating and speed-adjusting structures, the device improves its efficiency. Firstly, it can precisely adapt to the different patient tolerance levels. Whether the patient is elderly, post-operatively sensitive, or physically weak, the device can be adjusted to a soothing speed to avoid dizziness and discomfort. It can also adapt to a suitable rhythm for patients who need to quickly change positions, reducing the time local tissues are under pressure and lowering the risk of pressure ulcers.

This significantly broadens the device's applicability and comprehensively improves its practicality and reliability in clinical and home care.

[0037] The operation of the bedridden patient rotation assist device provided by this utility model is as follows: The user lays the patient on top of the bed 1. At this time, the user energizes the motor 18 to rotate. The output end of the motor 18 drives the rotating shaft 19 to rotate, which in turn drives the third gear 20 to rotate. Since the third gear 20 is meshed with the first gear 15 on one side, the rotation of the third gear 20 drives the first gear 15 to rotate, thereby driving the rotating column 9 to rotate. The rotation of the rotating column 9 drives the screw 10 to rotate. Since the screw 10 is threadedly connected to the concave plate 12, the rotation of the screw 10 drives the concave plate 12 to move. The movement of the concave plate 12 drives the rotating wheel 14 to move on the bottom side of the wedge block 6, thereby driving the wedge block 6 to lift the rotating plate 3 and rotate it along the rotating roller 4, so that the rotating plate 3 can turn the patient over. When it is necessary to adjust the turning speed, the user energizes the motor 23 to rotate. The output end of the motor 23 drives the lead screw 24 to rotate. Since the lead screw 24 is threadedly connected to the first gear 15 on one side, the rotation of the first gear 15 drives the first gear 15 to rotate, which in turn drives the rotating column 9 to rotate. The rotation of the first gear 10 drives the screw 10 to rotate. Since the screw 10 is threadedly connected to the first gear 15, the rotation of the first gear 10 drives the first gear 15 to rotate, which in turn drives the rotating column 14 to rotate. The ... The T-block 22 is present, and the rotation of the lead screw 24 causes the T-block 22 to move, which in turn causes the concave block 17 to move. At this time, the third gear 20 disengages from the first gear 15, while the fourth gear 21 and the second gear 16 re-engage. Since the radii of the first gear 15, the second gear 16, the third gear 20, and the fourth gear 21 are different, the rotation speed of the rotating column 9 is adjusted, which in turn adjusts the moving speed of the concave plate 12. At the same time, the lifting speed of the wedge block 6 increases, accelerating the angle adjustment speed of the rotating plate 3. Through a series of designs, this utility model achieves precise adjustment of the patient's rotation speed. It can dynamically adapt the operation intensity according to the patient's tolerance and avoid the risk of skin abrasion caused by inertial impact in traditional constant speed devices. It significantly improves the safety and humanization of the assisted rotation process and has outstanding substantial innovative value in the field of medical auxiliary devices.
