The industrial detection method of job stability in the warm and humid environment of digestive tract power detectorTechnical field
The present invention relates to digestive tract power testing equipment field more particularly to a kind of warm and humid environment of digestive tract power detectorThe industrial detection method of middle job stability.
Background technology
Digestive tract power detection be diagnosis for disease of digestive tract and postoperative function evaluation it is a kind of conveniently, safely, nothingThe high Examined effect of damage, diagnosis.Digestive tract power detection means mainly have esophageal pressure detection, anorectal pressure detection andStomach and intestine electrograph detects three kinds.Digestive tract power detector is the key equipment for implementing digestive tract power detection, detector performanceQuality, and the stability of working performance in certain circumstances, are directly related to the reliability of detection data, the diagnosis to doctorAs a result play the role of critical.In the prior art, in the digestive tract power detector of batch production, detection sample is selected at randomProduct carry out inspection, if it is detected that underproof product, then trace same batch product it is whether qualified.Not asking there is only missing inspectionTopic, product of problems cannot be guaranteed to detected, and traces and have certain difficulty, heavy workload.
Invention content
The purpose of the present invention is to provide a kind of industry inspections of job stability in warm and humid environment of digestive tract power detectorSurvey method, the stability to be worked under warm and humid environment alimentary canal dynamic detector are detected.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of industrial detection method of job stability in the warm and humid environment of digestive tract power detector, it is characterised in that：
On-line checking is carried out using circulation conveying pedestal carrying digestive tract power detector, to alimentary canal dynamic detectorOn-line checking includes the detection to Gastroenteric Electrical part and the detection to pressure detecting part,
The ring conveys the sine wave signal that pedestal inputs 150 μ V, 0.05Hz to Gastroenteric Electrical part, records digestive tract powerThe testing result A of the Gastroenteric Electrical part of detector output；
The ring conveys pressure of the pedestal to pressure detecting part input -100mmHg~450mmHg, and record alimentary canal is dynamicThe testing result B of the pressure detecting part of tension gauge output；
Ring conveying pedestal delivers digestive tract power detector along fixed orbit transports, and pass sequentially through preheating section,Constant temperature and humidity section, freeze-day with constant temperature section, room temperature section, the preheating section, constant temperature and humidity section, freeze-day with constant temperature section, room temperature section are closedSpace, the pressure of the preheating section are 1.2 times of standard atmospheric pressures, and temperature is 34-40 DEG C, relative humidity 75%, by whenBetween be 5min；The pressure of the constant temperature and humidity section is standard atmospheric pressure, and temperature is 40 DEG C, relative humidity 93.5%, byTime is 45min；The pressure of the freeze-day with constant temperature section is standard atmospheric pressure, and temperature is 40 DEG C, and relative humidity is 55% hereinafter, logicalThe time crossed is 15min；The pressure of the constant temperature zone be standard atmospheric pressure, temperature be 3 DEG C, by time be 3min；It is describedThe pressure of room temperature section is standard atmospheric pressure, and temperature is gradually brought to room temperature, by time be 5min；
Ring conveying pedestal respectively to Gastroenteric Electrical part, pressure detecting part input detection sine wave signal, pressure beWhat constant temperature and humidity section carried out,
Constant temperature and humidity section using uniformly sprayed into the confined space of constant temperature and humidity section atomized water realize moisturizing, atomized water withHigh pressure nitrogen is that carrier is atomized.
Preferably, the pressure that ring conveying pedestal is inputted to pressure detecting part is divided into low pressure detection pressure and high pressure detectionPressure, it is -100mmHg~100mmHg that low pressure, which detects pressure, and it is 100mmHg~450mmHg that high pressure, which detects pressure,.
Preferably, the low pressure detection pressure and high pressure detection pressure are the detection pressure of dynamic change.
The numerical value of testing result A within the scope of 143~157 μ V, the numerical value of testing result B be input pressure value (1 ±0.01) again, as qualified.
The beneficial effects of the invention are as follows：
The method of the present invention is suitable for industrial on-line checking, after setting, can be automatically performed entire detection process, examinesEfficient, detection frequency height is surveyed, comprehensively, detection environmental change is combined changes various, testing result reliability to the covering of detection numerical valueIt is high.
Specific implementation mode
In order to make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, tie belowSpecific embodiment is closed, the present invention is further explained, but following embodiments are only the preferred embodiment of the present invention, and not all.Based on the implementation example in the implementation mode, those skilled in the art's obtained other realities without making creative workExample is applied, protection scope of the present invention is belonged to.
