Multi-functional nursing bed, and its controlling system

Abstract

A multifunctional nursing bed is composed of left and right boards for turning body over, left and right buttock boards, cover plate of bedpan, thigh board, shank board and supporting frame. Its control system consists of information input module, control module with single-chip microprocessor, and PLC control system.

Description

technical field [0001] The invention relates to a medical and nursing bed, in particular to a multifunctional nursing bed and its control system. Background technique [0002] In hospitals and families, for the treatment and nursing of chronic patients and paralyzed patients, in addition to the treatment of drugs and injections, if the patients can receive the necessary physical care on the nursing bed, the activity of the patient's body can be greatly enhanced, and the Self-immunity can greatly reduce the occurrence of complications. For example, regular turning and lifting of the patient's back can strengthen the blood flow of the patient's back and buttocks, greatly reduce the occurrence of complications such as decubitus ulcers, and reduce unnecessary pain of. Most of the existing nursing beds are composed of two or three bed boards. Each bed board can only rotate around the same axis. The rotation operation is divided into two categories: manu...

AI Technical Summary

Problems solved by technology

Most of the existing nursing beds are composed of two or three bed boards. Each bed board can only rotate around the same axis. The rotation operation is divided into two categories: manual and electric. Manually shake the handles on the bed corresponding to each bed board, and realize the rotation and transposition of a single bed board through a transmission mechanism (such as a worm gear, a connecting rod mechanism, etc.). It is a motor-driven structure, thereby reducing the labor intensity of the nursing staff, but the existing nursing beds have the following disadvantages and deficiencies: there are few position changes that can be realized, and the existing nursing beds can realize some common postures ( Such as lifting the back, lifting the legs, bending the legs), but some special postures and postures (such as turning around, sitting, defecation) can not be realized. As disclosed in the Chinese utility model patent No. 02277156.5, a "multifunctional medical Nursing bed", this kind of nursing bed is characterized in that a movable bed frame is provided on the bed body, which is composed of a back board, a fixed board, one or more middle boards and one or more leg rest boards hinged to each other, and the fixed board or There is a convenient hole in the middle plate, and a movable cover plate on the same plane as the middle plate is set in the hole. Under the bed body, there is a pull rod device driven by a pull rod linear motor to move the bed frame up and down. The middle board is respectively connected with the linear motor of the back board and the direct motor of the middle board through connecting rods, and each linear motor is controlled by an electric control box; Turning over left and right and sitting posture and functions cannot be realized, and the linear motor is connected to each plate through a connecting rod, the transmission is not direct enough, and the structure is relatively complicated

In the Chinese utility model patent No. 02212458.6, "a block-type multifunctional nursing bed" is disclosed, and its bed frame is divided into a backrest module, a hip fixing module, a hip movable module, a leg module, and a foot module. There is also a toilet block between the buttocks fixed module and the buttocks movable module, and the two adjacent movable modules are hinged. This kind of nursing bed can also realize the functions of lifting the back, raising the legs, bending the legs, sitting, and defecating, but it cannot Realize the function of turning left and right, and its operation mode is manual operation, which is slow, time-consuming and laborious, and the operation is not convenient enough

In the Chinese utility model patent No. 02213135.3, a "turning over and back nursing bed" is disclosed. This kind of nursing bed can realize the functions of turning around and lifting the back, but other functions cannot be realized.
