Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a nursing bed capable of assisting a patient in turning over. Background Art

[0002] Nursing beds usually refer to beds specially used by patients in hospitals or nursing institutions. Such beds are designed with many functions to facilitate nursing care, such as adjustable bed height, wheels for easy movement, bedside tables and bedside tables for patients to use, and some are also equipped with nursing call systems, sputum drainage systems, handrails, etc. Nursing beds are mostly made of stainless steel, aluminum alloy or carbon steel to ensure durability and safety; After searching the patent number 202211047231.9, an auxiliary lifting nursing bed for orthopedic patients is disclosed, including a nursing bed body. The detection device includes a rectangular shell, a sliding rheostat, a toggle block, a first spring and a rotating shaft. The nursing bed body is connected to a rectangular shell, and the inner wall of the rectangular shell is fixedly connected to a sliding rheostat. The inner side of the rectangular shell is slidably connected to a toggle block, and the toggle block slides on the sliding rheostat. A first spring is fixedly connected between the toggle block and the inner wall of the rectangular shell, and the toggle block is rotatably connected to a rotating shaft on the side away from the sliding rheostat. The auxiliary lifting nursing bed for orthopedic patients achieves the purpose of changing leaflets and turning the patient over through the cooperation between the motor, the rotating block, the ratchet ring, the rotating disk and the winding roller, thereby solving the problem that the patient needs to be removed from the bed to change the bed sheet, which is very difficult to operate and may cause harm to the patient during the movement process; The lower limb rehabilitation exercise device with lifting and rocking functions used in the above-mentioned patents and the prior art background still has certain shortcomings. For example, most of the existing nursing beds can only be adjusted by lifting and lowering, which makes the patients maintain the same posture for a long time, thereby increasing body pressure and possibly causing skin problems such as bedsores. At the same time, due to the lack of appropriate turning over function, the patient's mobility in bed is restricted, and the nursing staff needs to turn the patient over manually when turning the patient over, which not only increases physical exertion and work intensity, but also may cause fatigue and occupational injury risks for the nursing staff, thereby affecting the patient's recovery and quality of life.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the nursing bed that can assist patients in turning over can adjust the posture according to the needs of the patients by assisting the patients in turning over, thereby reducing the discomfort caused by long-term bed rest, and also reducing the physical labor of nursing staff, reducing the work intensity, thereby improving the physical health and comfort of the patients, and at the same time, through good support and buffering, the chest position of the patients can be kept more stable when turning over, thereby helping the patients to maintain the correct body position, thereby reducing the discomfort caused by exercise, reducing the discomfort and risk of turning over, and thereby reducing the pressure between the chest and the mattress, and then through good back support, the discomfort caused by body gravity can be reduced, so that the patients can turn over more comfortably and reduce the back discomfort and pain caused by improper posture; 1. A bed board, a turning board, a first bidirectional threaded rod, a first internally threaded sleeve, a first hinge rod and a first motor are provided, and the turning board is rotatably connected to the front and rear ends of the bed board, and the first motor can be started respectively according to the turning direction requirements. Since the first hinge rod is in an inclined state and is rotatably connected to the top of the first internally threaded sleeve and the bottom of the turning board, the output end of the first motor drives the first internally threaded sleeves at the left and right ends of the first bidirectional threaded rod to slide in opposite directions, so that the first internally threaded sleeve drives the turning board to form a turning structure through the first hinge rod, and then the turning board is turned at an inclined angle on the side wall of the bed board, so that the turning board assists the patient to turn over in different directions, and then adjusts the posture according to the patient's needs, thereby reducing the discomfort caused by long-term bed rest, and also reducing the physical labor of nursing staff, reducing the work intensity, thereby not only improving the patient's physical health and comfort, but also effectively supporting the work of nursing staff; 2.

The first support plate is rotatably connected to the connecting rod through a "U"-shaped structure, and the first support plate and the connecting rod combination are rotatably connected to the front and rear ends of the bed board respectively, so that the second motor can be started according to the chest direction of the patient turning over. Since the first synchronous pulley on the left side of the bed frame and the first synchronous pulley on the right side of the bed frame are connected together through the first belt sleeve, the second motor drives the first threaded rod to rotate synchronously through the mutual cooperation between the first synchronous pulley and the first belt, and is also connected to the first threaded rod through the inner side wall of the second internally threaded sleeve by threads. The upper end of the second internally threaded sleeve is rotatably connected to the bottom of the first support plate, so that the second internally threaded sleeve drives the connecting rod and the first support plate to flip into a "V"-shaped structural state. At the same time, an airbag is fixedly installed inside the first support plate.
