CN101961238A - Peristalsis monitor - Google Patents

Abstract

The invention relates to a peristalsis monitor which comprises an electrode, an amplifier, an AD (Alternating current-Direct current) converter, a singlechip and a U-disk storage system, wherein the electrode is connected with the amplifier through a lead; a signal output end of the amplifier is connected with a signal input end of the AD converter; a signal output end of the AD converter is connected with the singlechip through a lead; and the singlechip is connected with the U-disk storage system and used for controlling the U-disk storage system and inputting converted electric signals while peristalsis to the U-disk storage system. The monitor can be used for recording the electric signals while the peristalsis for a long time, timely judging whether to recover the peristalsis or not and monitoring the peristalsis degree, which has important significance to timely feeding a patient and enhancing the nutrition.

Description

The enterokinesia monitor

Technical field

The present invention relates to a kind of simple and practical enterokinesia monitor, the instrument whether a kind of specifically timely patient's of judgement enterokinesia has recovered belongs to medical instruments field.

Background technology

Along with the development of medical science, also more and more careful to the monitoring of every index of patient.For the patient of abdominal postoperative, or ileac patient, in case enterokinesia recovers, will in time take food, strengthen nutrition.Therefore, whether be very important observation item in the enterokinesia of in time finding patient if recovering.

All be now to carry out auscultation by stethoscope at patient's abdominal part to judge whether existing borborygmus of patient clinically, this has the following disadvantages: 1. because enterokinesia is intermittent, in tens seconds of auscultation, not necessarily there is borborygmus to take place, if 2. a little less than the borborygmus, when ambient noise is big, leaks probably and listen.3. once generally listened for tens seconds, can not reflect the frequency of enterokinesia in a period of time.Therefore, need a kind of enterokinesia that can in time monitor patient whether to recover, and the equipment of the degree of recovering

Summary of the invention

At above deficiency, the invention provides a kind of enterokinesia monitor.

The present invention realizes by following technology:

It is made up of on and off switch, electrode, amplifier, AD converter, single-chip microcomputer, USB flash disk storage system, shell, battery power supply system, alarm lamp.Electrode is made up of electrode A, electrode B, electrode C, electrode is fixed on the anal canal, certain at interval distance, and link to each other with amplifier by a long lead, the signal output part of amplifier links to each other with the signal output part of AD converter by lead, and the signal output part of AD converter links to each other with single-chip microcomputer by lead.Single-chip microcomputer connects also control USB flash disk storage system, the signal of telecommunication that can be when the enterokinesia after its input transforms.Signal in the USB flash disk can be analyzed on computers.

The invention has the beneficial effects as follows: the signal of telecommunication in the time of can noting down intestinal peristalsis promoting for a long time, in time judge whether to have recovered wriggling, and the degree of wriggling.To patient's feed, strengthening nutrition has important meaning in time for this.

The specific embodiment

Be described in detail with reference to 1 pair of structure of the present invention of accompanying drawing and operation principle.

Enterokinesia monitor of the present invention, comprise electrode 7, amplifier 6, AD converter 5, single-chip microcomputer 3, USB flash disk storage system, electrode 7 links to each other with amplifier 6 by a lead, the signal output part of amplifier 6 links to each other by the signal input part of lead with AD converter 5, the signal output part of AD converter 5 links to each other with single-chip microcomputer 3 by lead, single-chip microcomputer 3 connects also control USB flashdisk storage system 1, the signal of telecommunication during enterokinesia after its input transforms.Single-chip microcomputer 3 also is connected with alarm lamp 4.

Described electrode 7 is made up of electrode A, electrode B and electrode C, and each electrode is fixed on the anal canal, certain at interval distance.

During use, USB flash disk is inserted the interface of USB flashdisk storage system 1, three electrodes 7 are fixed on the anal canal, the about 3cm in space, and be placed on patient's the about 15cm of anal, turn on the power switch.At this moment, the signal input amplifier 6 that electrode 7 is gathered, signal is imported AD converter 5 through amplifying after, import single-chip microcomputer 3 behind AD converter 5, and single-chip microcomputer 3 processing signals degree deposit signal in USB flash disk by conversion chip 2.The signal of telecommunication when data of storing in the USB flash disk this moment are enterokinesia.When USB flash disk is filled with or system when breaking down, single-chip microcomputer 3 can 4 flickers of control alarm lamps, and can change USB flash disk or powered-down this moment.Information in the USB flash disk can be analyzed in computer.This is more accurate and comprehensive than the information that the short time stethoscope is obtained.
