Description

Technical Field

[0001] This utility model relates to the field of nursing chair technology, and in particular to a nursing chair. Background Technology

[0002] A nursing chair is a medical assistive device designed specifically for patients with limited mobility or those who are bedridden for extended periods. It primarily helps patients adjust their posture, move around, and perform daily activities. Its core functions include an adjustable backrest, leg support, armrests, and anti-slip casters. Some models are equipped with electric height adjustment, swivel seats, or integrated bedpans to meet diverse care needs. The reasons for using a nursing chair are: firstly, it effectively alleviates the risk of muscle atrophy and bedsores caused by prolonged bed rest, promoting blood circulation through posture adjustment; secondly, its assisted transfer function reduces the physical exertion of caregivers and lowers the risk of secondary injuries during transport; thirdly, integrated designs (such as bedpans and trays) enhance patient autonomy and reduce the burden on family caregivers; and fourthly, stability and safety features (such as anti-tipping locks and limit latches) ensure patient safety when using it independently. Nursing chairs are particularly suitable for post-operative rehabilitation, stroke sequelae, or severe osteoporosis patients requiring long-term immobilization, and are an important assistive tool for homes, hospitals, and nursing homes.

[0003] An existing nursing chair (publication number: CN216021730U) has at least the following drawbacks:

[0004] In the aforementioned patent, the seat can be raised, lowered, and rotated to adapt to different height scenarios (such as transferring patients or using the toilet). Safety buckles (rotating clips + pins) prevent the seat from accidentally separating. However, the manual lifting and lowering relies on human power and is relatively cumbersome to operate. At the same time, when the patient is unable to get out of bed on their own, caregivers need to lift the patient off the bed and sit on the seat, which requires high physical strength from caregivers and makes it inconvenient to use, thus having certain limitations.

[0035] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0036] When the user needs to use the mobile cart 1, especially if the patient is lying in bed and unable to get up, the drive motor 8 is activated to rotate the first threaded post 6. This converts the rotational motion of the first threaded post 6 and the first threaded hole 7 into linear motion, causing the seat 2 to move forward. Then, the electric push rod 19 is activated to push the seat 2 upwards, supported by the two third support plates 20, moving the seat 2 to the top of the electric push rod 19's stroke. Simultaneously, the third support plates 20 remain in place, ensuring the seat 2's height exceeds the bed's height. The second threaded post 22 is then rotated to unscrew it from the second threaded hole 21. The second support plate 18 is then rotated to the other side of the seat 2, and the handrail 13 is rotated towards the seat back. The stop block 16 limits the handrail 13, ensuring the top surface of the seat 2 is unobstructed by the handrail 13 and the second support plate 18, thus pushing the mobile cart 1 forward. The seat 2 is moved onto the bed surface, and the bottom of the trolley 1 can be inserted under the bed. This is suitable for patients in positions on the inside or outside of the bed. With the help of a caregiver, the patient sits up and leans against the seat 2, slowly moving to the top of the seat 2. After sitting down, the two handrails 13 are rotated to reset, and the second support plate 18 and handrails 13 are connected through the second threaded hole 21 and the second threaded post 22 to limit the patient's position. The trolley 1 is then pulled to move the patient through the seat 2, removing the patient from the bed. The drive motor 8 is then restarted to move the seat 2 back to its original position on the top of the trolley 1, with the patient's feet resting on the top of the trolley 1. This allows for precise adjustment of the seat 2's position. Through height and fore-aft adjustments, the seat 2 can be fitted to or placed on the bed surface. Caregivers can then help the patient sit on the seat 2 without the patient needing to get out of bed or be lifted manually. This method requires minimal effort and eliminates the need for manual operation of the lifting mechanism, saving energy and making it practical and convenient to use.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
