Description

Technical Field

[0001] This utility model belongs to the field of medical devices, specifically relating to a back massage control device for a nursing bed. Background Technology

[0002] Nursing beds are nursing facilities designed according to patients' bedridden living habits and treatment needs. They are often used in conjunction with treatment or rehabilitation equipment. Patients using nursing beds usually have lost or limited independent mobility and have difficulty getting up, especially patients with total paralysis. The process of changing from a lying to a sitting position relies entirely on the assistance of the backrest. Caregivers usually need to raise the backrest to support the patient. However, existing backrests cannot provide sufficient support for the patient's waist, forcing the patient to exert force on their own waist when sitting up or lying flat, which can easily cause secondary injury to the patient. Utility Model Content

[0003] The purpose of this utility model is to provide a back massage control device for a nursing bed that uses a hydraulic telescopic rod to push a torque arm to drive a first rotating shaft to rotate, which in turn drives a rotating arm to rotate and flips the backrest board under the action of the rotating arm. The rotating arm drives a push plate to rotate through a second rotating shaft to support the patient's waist, thereby reducing secondary injuries caused by the patient's own exertion during lying down or sitting up.

[0004] Based on the above objectives, the present invention adopts the following technical solution: a back massage control device for a nursing bed, comprising a bed frame and a bed board assembly. The bed frame is composed of multiple cross-shaped connecting rods, and a universal wheel is provided at the bottom of the bed frame. It also includes telescopic legs, with connecting rods between the telescopic legs and guide wheels at the bottom of the telescopic legs. The telescopic legs are located at the bottom of the bed board assembly. The bed board assembly includes a footboard, a legboard, an abdominal board, and a backboard arranged from left to right. The footboard and legboard are connected by a first hinge seat, the legboard and abdominal board are connected by a second hinge seat, and the abdominal board and backboard are connected by a third hinge seat. A through hole is provided at the top of the backboard, and a back massage pad is provided at the through hole of the backboard.

[0005] Furthermore, the bed board assembly has a front headboard and a rear headboard at both ends along its length. A mounting frame is provided at the bottom of the abdominal bed board and near the front headboard. The mounting frame includes a mounting plate at the bottom of the front headboard. A set of parallel fixed connecting rods is provided on the mounting plate away from the front headboard. The fixed connecting rods are L-shaped and are fixedly connected to the abdominal bed board. The assembly also includes a massage pad adjustment component.

[0006] Furthermore, the massage pad control assembly includes a hydraulic telescopic rod, one end of which is screwed to the front end face of the mounting plate. It also includes a first rotating shaft, which is located between the opposite faces of the fixed connecting rod and rotates in coordination with the fixed connecting rod. The assembly also includes a torque arm, which is fixedly connected to the first rotating shaft via a pin. The output end of the hydraulic telescopic rod is fixedly connected to the torque arm. It also includes a set of parallel rotating arms, which are connected to the first rotating shaft via pins.

[0007] Furthermore, the massage pad control assembly also includes a second rotating shaft, with a fixed connecting rod on the outside of the second rotating shaft. The fixed connecting rod is fixedly connected to the backrest bed board, and the second rotating shaft and the fixed connecting rod rotate in coordination. It also includes a push plate, which is fixedly connected to the second rotating shaft.

[0008] Furthermore, armrests are provided on both sides of the abdominal bed board, and the armrests are hinged to the abdominal bed board. A massage module is provided inside the back massage pad.

[0009] This invention offers the following advantages over existing technologies: By using a hydraulic telescopic rod to push a torque arm, the invention drives a first rotating shaft to rotate. When the first rotating shaft rotates, it causes the rotating arm to rotate by the same angle, thereby causing the backrest board to flip under the action of the rotating arm. This allows the patient's upper limbs to gradually rise from a supine position. Then, during the swinging of the rotating arm, the second rotating shaft rotates, causing the push plate to rotate along with the second rotating shaft. This push plate supports the patient's lower back, making it easier for the patient to sit up or lie down with the backrest board, reducing secondary injuries caused by the patient's own exertion during the process of lying down or sitting up.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model. Example 1

[0016] like Figure 1-4 The nursing bed back massage control device shown includes a bed frame 1 and a bed board assembly. The bed frame 1 is composed of multiple cross-shaped connecting rods. A universal wheel 2 is provided at the bottom of the bed frame 1. It also includes telescopic legs 17. A connecting rod is provided between the telescopic legs 17. A guide wheel 3 is provided at the bottom of the telescopic legs 17. The telescopic legs 17 are located at the bottom of the bed board assembly. The bed board assembly includes a footboard 5, a legboard 6, an abdominal board 10, and a backboard 11 arranged from left to right. The footboard 5 and the legboard 6 are connected by a first hinge seat 7. The legboard 6 and the abdominal board 10 are connected by a second hinge seat 8. The abdominal board 10 and the backboard 11 are connected by a third hinge seat. A through hole is provided at the top of the backboard 11, and a back massage pad 12 is provided at the through hole of the backboard 11.

[0017] The bed board assembly has a front headboard 13 and a rear headboard 4 at both ends along its length. A mounting frame 15 is provided at the bottom of the abdominal bed board 10 and near the front headboard 13. The mounting frame 15 includes a mounting plate at the bottom of the front headboard 13. A set of parallel fixed connecting rods are provided at the end of the mounting plate away from the front headboard 13. The fixed connecting rods are L-shaped and fixedly connected to the abdominal bed board 10. The assembly also includes a massage pad adjustment component.

[0018] The massage pad control assembly includes a hydraulic telescopic rod 16, one end of which is screwed to the front end face of the mounting plate. It also includes a first rotating shaft 18, which is located between the opposite faces of the fixed connecting rod and is rotatably engaged with the fixed connecting rod. The assembly further includes a torque arm 19, which is fixedly connected to the first rotating shaft 18 via a pin. The output end of the hydraulic telescopic rod 16 is fixedly connected to the torque arm 19. The assembly also includes a set of parallel rotating arms 14, which are connected to the first rotating shaft 18 via pins.

[0019] The massage pad control assembly also includes a second rotating shaft 21, with a fixed connecting rod on the outside of the second rotating shaft 21. The fixed connecting rod is fixedly connected to the backrest bed board 11, and the second rotating shaft 21 and the fixed connecting rod are rotatably engaged.

[0020] The abdominal bed board 10 is provided with armrests 9 on both sides, which are hinged to the abdominal bed board 10. The back massage pad 12 is provided with a massage module.

[0021] In this embodiment, the height of the footrest 5 is controlled by the telescopic outrigger 17, thereby causing the legrest 6 to rotate with the footrest 5. This allows the patient's legs to bend naturally when the footrest 5 is lowered. When it is necessary to change the patient from a supine position to a backrest position, the hydraulic telescopic rod 16 is extended, thereby pushing the torque arm 19 to rotate the first rotating shaft 18. When the first rotating shaft 18 rotates, it causes the rotating arm 14 to rotate by the same angle. Since the rotating arm 14 is fixedly connected to the second rotating shaft 21 by a pin, and the second rotating shaft 21 is connected to the backrest bed through a rotating shaft seat... The backrest board 11 is connected, allowing it to flip under the action of the rotating arm 14, gradually raising the patient's upper limbs from a supine position. Then, due to the rotation of the second rotating shaft 21, the push plate 20 rotates with the second rotating shaft 21 to support the back massage pad 12. At the same time, since the patient's lower back is placed on the back massage pad 12, the push plate 20 supports the patient's lower back during the process of lying down or sitting up, making it easier for the patient to sit up or lie down with the backrest board 11, reducing secondary injuries caused by the patient's own exertion during the process of lying down or sitting up.
