High-precision dynamic weighing sickbed system and automatic control method thereof

Abstract

The invention relates to a high-precision dynamic weighing sickbed system and an automatic control method thereof and aims to solve the problems that weight detection of patients is not dynamic and in real time in the prior art, and errors cannot be removed completely. The key points of the technical scheme are as follows: the high-precision dynamic weighing sickbed system adopts commercial power for power supply and comprises a bed board, a bedstead, a control motor and support props and further comprises a control device and pressure sensors, wherein the bedstead is movably connected with the bed board and the control motor; the support props are provided with lifting cylinders; the bed board comprises an upper bed board and a lower bed board which are hinged to each other; the lower surfaces of the upper bed board and the lower bed board are both fixedly connected with the support props; the lifting cylinders are all driven by the control motor; the control motor is electrically connected with the control device; each support prop is provided with a pressure sensor; the pressure sensors are electrically connected with the control device.

Description

technical field [0001] The invention relates to a hospital bed and its automatic control method, in particular to a hospital bed high-precision dynamic weighing system and its automatic control method. Background technique [0002] The current research has made great progress in the function of the hospital bed, and more and more reflects the important position of the hospital bed in high-tech medical care. For example, the following patents or documents record the changes and innovations of the hospital bed or related products: [0003] A hospital bed weighing system / Shenzhen Tsinghua University Research Institute Shenzhen Lihe High-Tech Co., Ltd. / / Application number: CN201210110652.1 [0004] The invention discloses a hospital bed weighing system, which includes a bed surface, an upper frame, a load cell and a lower frame from top to bottom, the upper frame is connected to the bed surface, and at least three scales are arranged between the lower frame and the upper frame. ...

AI Technical Summary

Problems solved by technology

[0022] The purpose of the present invention is to solve the current technical solutions that the detection of the patient's weight is not real-time dynamic, and the error removal is not perfect, resulting in low precision of these technical solutions, which is of little clinical significance. At the same time, these technical solutions The application of these weight data is not sufficient, it is only a simple recording function, and it is also very deficient in the control and humanization of the hospital bed. It provides a high-precision, sufficient data application that can assist doctors in monitoring the patient's physical condition.
