Abstract

The invention relates to a medical infusion pump alarming sound power amplifier power supply intelligent control system comprising a power amplification module and an electronic switch module. The power amplification module comprises a power amplification chip and an amplification circuit connected with the power amplification chip. The input end of the power amplification module is connected with audio frequency signals, and the output end of the power amplification module is connected with a loudspeaker. The power supply input end of the power amplification chip is connected with the output end of the electronic switch module. The electronic switch module comprises a power supply. The input end of the electronic switch module is connected with the single-chip microcomputer, and the single-chip microcomputer is used to control the communication between the power supply and the power amplification chip. The medical infusion pump alarming sound power amplifier power supply intelligent control system is advantageous in that the noises can be reduced, and the energy consumption can be reduced.

Description

technical field [0001] The invention relates to a power supply control system for medical infusion pump alarm. Background technique [0002] Even if there is no input signal after the integrated audio power amplifier is powered on, it will generate a certain amount of white noise itself. This white noise causes the human ear to hear a slight continuous noise near the speaker when the infusion pump device is not beeping. For patients who are undergoing infusion, this continuous noise will make people feel restless and anxious, and this white noise cannot be completely eliminated for the power amplifier circuit in operation. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a control system that eliminates noise and reduces energy consumption. [0004] In order to achieve the purpose of the above invention, a medical infusion pump alarm sound power amplifier power intelligent control system ...
