CN203861625U - Gastrointestinal endoscope sterilization effect detection system - Google Patents

Abstract

The utility model discloses a gastrointestinal endoscope sterilization effect detection system, which comprises a sterilized membrane filter, an air filter, a pump pipe with a connector and a bacterium collector, wherein the connector end of the pump pipe with the connector is connected to an eluent outlet of a gastrointestinal endoscope, and the other end of the pump pipe is connected with an inlet of the bacterium collector; an outlet of the bacterium collector is communicated with the membrane filter through a pipeline; the air filter is mounted at the top end of the membrane filter. According to the system, the special connector for connecting an opening of the endoscope is additionally arranged on the basis of using the conventional pump pipe, so that complete sealing for sampling is implemented, and the accuracy of a detection result is improved.

Description

A detection system for disinfection effect of gastroenteroscope

technical field

The utility model relates to a microorganism detection and sampling device, which is a special device for detecting the cleaning and disinfection effect of gastroenteroscope.

Background technique

Gastrointestinal scopes and other similar medical devices need to be in contact with the mucous membranes and ulcers of patients or users. In order to ensure that no additional infection risks are brought to users, gastrointestinal scopes must be cleaned and disinfected before use. According to the relevant provisions of GB15982-2012 "Hospital Disinfection Hygienic Standards", endoscopes are moderately dangerous medical equipment, and the bioburden of the inner wall after disinfection must be less than 20CFU/piece. The standard recommends the detection method for endoscopy as the elution-membrane filtration method. That is, inject 50mL of eluent containing the corresponding neutralizing agent through the biopsy port, flush the gastroenteroscope pipeline, and receive it in another sterile container (peristaltic pump can be used to assist in collecting the recovered liquid); transfer the container to the 100-level laminar flow, Take 1ml to inoculate directly, pour the remaining liquid into an open membrane filter, filter and culture on a membrane. During the elution and eluent recovery stages of this detection method, it cannot be operated in a clean environment, and the container mouth is exposed for a long time, so there is a high risk of contamination, and the accuracy of the test results for low-pollution samples is low.

Contents of the invention

The purpose of the utility model is to improve the existing detection device and provide a gastroenteroscope disinfection effect detection system with high detection rate, reasonable structure, convenient use and low contamination risk.

In order to achieve the above object, the utility model includes a sterilized membrane filter, an air filter, a pump tube with a joint and a bacteria collection instrument, and the joint end of the pump tube with a joint is connected to the eluent outlet of the gastroenteroscope The other end is connected to the inlet of the bacteria collection instrument, and the outlet of the bacteria collection instrument is connected to the membrane filter through a pipeline, and the top of the membrane filter is equipped with an air filter.

Compared with the prior art, the utility model adds a special joint to connect the opening of the gastroenteroscope on the basis of using the original pump tube, adds a fully enclosed membrane filter, and the eluent is filtered and concentrated through the membrane filter In this way, the full sealing of sampling in ordinary environments is realized, and the accuracy of detection results is improved.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

The utility model is described in further detail in conjunction with the following examples, the following examples are explanations of the utility model and the utility model is not limited to the following examples

Example 1:

Assemble the sterilized membrane filter 4, install the air filter 5, and prepare the pump tube with a special connector 2 (this step can be ignored if a disposable filter is used);

Use the special connector 2 to match the opening of the sample to be tested and start the bacteria collector 3, inject the eluent into the upper part of the gastroenteroscope 1, and the eluent will be quickly and fully transferred to the membrane filter 4 cup with the operation of the bacteria collector 3 During the process, stop the bacteria collector 3, and then add a clip to cut the hose and insert it into the upper end of the air filter to close the cup. The closed membrane filter cup is sent to the inspection room. Use a syringe to draw 1ml of liquid for direct inoculation, and then use a special micrometer to inoculate it. The limit instrument filters all the eluent in full, opens the membrane filter, takes out the filter membrane and cultures on the surface of the agar plate.

Example 2:

Assemble the sterilized membrane filter (this step can be ignored if using a disposable filter), install the air filter, and prepare the pump tube with a special connector;

Use a special connector to match the opening of the sample to be tested and start the bacteria collector, inject the eluent into the upper part of the gastroenteroscope, and the eluent will be quickly and fully transferred to the membrane filter cup with the operation of the bacteria collector, and take it out with a syringe After 1ml of liquid, use a special protective cap to seal; stop the bacteria collector, then cut off the hose at the rear end of the special connector about 3cm, connect the air filter, use the bacteria collector to directly filter the eluent, and then close the cup; The closed syringe and membrane filter cup are sent to the inspection room, the liquid in the syringe is directly inoculated, the membrane filter is opened, and the filter membrane is taken out and cultured on the surface of the agar plate.

The above-mentioned specific embodiments are used to explain the utility model, rather than to limit the utility model. Within the spirit of the utility model and the protection scope of the claims, any modification and change made to the utility model fall into the scope of the utility model. protected range.
