Description

Endoscope Leakage Tester and Endoscope Leakage Tesing Method by using the same}

The present invention relates to an endoscope liquid inspection apparatus and an endoscope liquid test method using the same, and more specifically, to test the liquid according to whether the damage to the end of the endoscope provided with at least one pipeline through which the liquid or gas flows, etc. It relates to an endoscope liquid inspection device and an endoscope liquid test method using the same.

Endoscopy includes a small camera, such as a CCD sensor, at one end that can be inserted into the body to inspect, operate, or visually inspect the internal organs, such as the bronchi, esophagus, stomach, heart, and colon. It is a device designed to observe by inserting a machine inside the organ equipped with a scope unit.

The endoscope is provided with a plurality of pipes for injecting chemicals or gases, and a pipe for inserting a plurality of cables for controlling the movement of a small camera or for irradiating light, and inspecting whether these pipes are leaky before the procedure. The procedure is essential. This can cause damage to organs due to leakage of chemicals, gases, and waste fluids injected through the liquid portion of the pipeline, and it can prevent the accurate measurement of the inspection site or reduce the performance of optical fibers or CCDs. Because.

In this regard, the conventional endoscope liquid test was a method of identifying bubbles generated by immersing the endoscope in water and injecting air into the inside, and this method can be automated because the human eye sees and judges. There was no inconvenience.

There has been a lot of research on the tester device for detecting the endoscope liquid automatically and many products are on the market.

In addition, in order to automatically detect the endoscope liquid in this way, the inside of the endoscope is pressurized and closed, and a method of determining whether the liquid is detected by detecting an internal pressure change is common. In Japanese Patent Application Laid-Open No. 4-221733 or Japanese Patent No. 3186438, it is determined whether or not liquidity is detected by detecting a pressure difference between a gas pressure inside an endoscope and a pressure of a pressurized gas supplied from a pressurized gas source using a car arm sensor. Japanese Patent Laid-Open Publication No. Hei 5-220110 discloses a method of detecting an internal pressure of an endoscope by a gauge pressure sensor.

However, the above-described conventional endoscope automatic detection method requires a complicated piping structure in addition to the expensive sensor, and also requires a complicated calibration process, which generally complicates the system or uses a gauge pressure sensor. When a pressure sensor having a scale is required and the pressure change caused by the liquid is small, there is a problem that a long time measurement is required to secure the accuracy.

In addition, the Korean Patent Publication No. 2006-69492 discloses a "leak tester", the leak tester is controlled by the pressure control unit for controlling the pressurizing device to perform the first press operation and the second press operation, 1 The pressure value inside the endoscope at the time of stopping the pressurizing operation and the pressure change amount inside the endoscope after the second pressing stops, and the volume of the endoscope is estimated on the basis of the pressure value to obtain the pressure change information and the endoscope therefrom. By judging the leak state of, not only a complicated judging means is used, but also a complicated correction process is required, and there is a problem in that the user has to check the leak by the submerged bubble method when the judging result becomes an indeterminate area.

In addition, Korean Patent Publication No. 1052893 discloses an "endoscopic leak test apparatus and a leak test method using the same", but the endoscope leak check apparatus is a pressure sensor that measures the pressure in real time or periodically from the endoscope pipe, Set a deviation value to determine whether the maximum pressure value corresponding to the constant pressure supplied to the pressure sensor and the pressure value measured from the pressure sensor are within an allowable range, and determine whether a leak occurs according to whether the deviation is within the allowable error range. Therefore, not only complicated determination means are used, but also complicated correction processing is required, and the measurement range of the pressure sensor has an error range of ± 3 to 5 mmHg, which causes problems in precision measurement of leakage.
