Medical apparatus alarm device based on auditory alarm signals and application method

Abstract

A medical apparatus alarm device based on auditory alarm signals comprises a signal collecting circuit, a processing circuit and a prompting circuit which are installed on a circuit board. The circuitboard is installed in an element box of a medical apparatus alarm system body. The medical apparatus alarm is connected with the signal collecting circuit, the processing circuit and the prompting circuit through wires. In the application method of the medical apparatus alarm device based on the auditory alarm signals, a single-chip microcomputer conducts compiling through a PC, during work, theprocessing circuit can output pulse signals with different widths according to the main control circuit board of the medical apparatus alarm system body and different types of signals input in the twosignal output ends, and a loudspeaker sends out three types of sounds. There are few peripheral elements, the size is reduced, cost is lower, no data can be lost, no adjustment needs to be made, workis more reliable, produced sounds are more real, the comma difference is larger, and operators can more easily distinguish the alarm emergency degree.

Description

technical field [0001] The invention relates to the supporting field of medical facilities, in particular to a medical device alarm device and an application method based on an auditory alarm signal. Background technique [0002] The GB9706.1-2007 standard is a general safety requirement for medical electrical equipment. It pointed out that: in order for the operator to use hearing to identify the occurrence of alarm signals in different states, the alarm sound must be heard in the background noise environment, and it must be different from other sounds; among them, the sound pressure level of the medium priority alarm signal should be The sound pressure level of the high-priority alarm signal should not exceed the sound pressure level of the low-priority alarm signal, and the sound pressure level of the low-priority alarm signal should not exceed the sound pressure level of the medium-priority alarm signal, so that the volume difference of different levels can be passed (ge...

AI Technical Summary

Problems solved by technology

[0004] The alarm unit used in the existing medical equipment alarm system is generally composed of LM386 operational amplifier, 555 clock chip, resistors, capacitors, etc. This alarm unit uses many integrated circuits and peripheral components, which leads to the alarm of medical equipment using the alarm unit. The volume of the system is relatively large, which increases the probability of failure. At the same time, the 555 clock chip is limited by the output frequency range, and the width of the pulse signal output by it is limited. When the peripheral components are used, it is necessary to repeatedly debug the peripheral components. The debugging process takes a lot of time, which brings great difficulties and inconvenience to the debugging personnel. After debugging, the error of the frequency domain range is relatively large, and the sound output by the subsequent speakers Distortion will occur, and the reliability of the medical device alarm system cannot be guaranteed
