Embodiment Construction

[0037] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] Such as Figure 1 to Figure 3As shown, a pressure distributed sensor is characterized in that it includes a pressure sensitive conductive material, a comb electrode, a PCB board, a 74HC138 chip and a CD4067 chip, the 74HC138 chip and the CD4067 chip are located below the PCB board, and the comb electrode is welded on On the PCB board, the pressure-sensitive conductive material is covered on the PCB board welded with comb-shaped electrodes, and the comb-shaped electrodes are evenly distributed on the PCB board in an arrangement of rows and columns. The inductive conductive material and each comb-shaped electrode form a variable resistor, and its resistance value changes with pressure. A comb-shaped electrode is a pressure collection point, and the pressure collection point is electrically connected to the CD4067 chip. The 74HC138 chip ...

Abstract

The invention discloses a pressure-distributed sensor, and an intelligent sickbed monitoring system and an intelligent sickbed monitoring method. In terms of a long-term bedridden patient, terminals such as a mobile phone, a tablet personal computer, and so on could help the patient to finish a series of movements of rising back, turning over, pumping legs, and to prompt the patient to turn over according to the data obtained by the pressure-distributed sensor so as to prevent the generation of chronic pressure sores, and use a camera to monitor the state of the patient. The system is composed of power-driven sickbeds, Arduino, an inertial sensor, the pressure-distributed sensor, a Raspberry Pi, the camera, a server and a Web end. The inertial sensor could obtain the posture angle of the sickbed and transmit the angle data to the Raspberry Pi to achieve the feedback control of a linear motor. The Raspberry Pi is used as data terminal of the single intelligent sickbed while the server is used as a data control terminal of a plurality of intelligent sickbeds and could be used for monitoring the sickbeds via the Web end and monitoring the physiological status of the patient and the states of the intelligent sickbeds.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to a pressure distributed sensor and an intelligent hospital bed monitoring system and monitoring method thereof, in particular to the application of an inertial sensor and a pressure distributed sensor in detecting the movement state of a hospital bed and the pressure distribution of a human body respectively. Background technique [0002] A medical bed is a device used to carry patients in a hospital ward. Some medical beds can change the posture by external force to assist in adjusting the patient's position, and some of the accessories have the effect of promoting the patient's recovery. Different types of medical beds have their own advantages, but with people's demand for medical security, the beds are gradually becoming more complicated without losing safety. [0003] Although many enterprises in our country are producing medical devices, our country's primary medical equipmen...
