Description

Contamination amount sampling device for inner pipeline of endoscope

Technical Field

The utility model relates to an scope sampling technical field especially relates to a contamination volume sampling device of scope internal pipeline.

Background

Method for sampling endoscopes after sterilization as described in the standard for hospital sanitation and hygiene (GB 15982-2012): the method comprises the steps of taking a cleaned and disinfected endoscope, extracting 50mL of eluent containing a corresponding neutralizer by using a sterile injector, injecting the eluent into an endoscope flushing pipeline from a biopsy port, collecting and inspecting the whole amount of the eluent for flushing the endoscope pipeline, judging that the cleaning, disinfection and sterilization are unqualified when the total number of microorganisms exceeds a certain standard, and cleaning, disinfection and sterilization are needed again until the result of the bacteria staining sampling detection is qualified.

The endoscope structure includes: the endoscope comprises an insertion pipe, an operation part, a universal cable, a light guide connector and related accessories, wherein the inner pipeline of the endoscope comprises a pliers pipeline, a suction pipeline, an auxiliary water feeding pipeline, a gas/water feeding pipeline and the like, the number of the inner pipelines of the endoscopes in different types and models is greatly different, the length of the pipeline is different, the pipe diameter of the pipeline is thick or thin, and a valve body and a connector are arranged on the endoscope, so that the endoscope is of a self-contained standard structure.

At present, three methods for sampling the contamination quantity of an endoscope internal pipeline are provided. In the first method, a tube is connected to the tip of an endoscope during sampling, an aseptic syringe is used for extracting eluent, the eluent is injected into and washed from an endoscope pipeline from a biopsy port of an operation part, and the eluent flowing out of the endoscope pipeline is collected into a bottle through a peristaltic pump. Run into the very thin scope of pipeline, the liquid is annotated to the biopsy mouth, often can be because it is too big hard, make the eluant flow from attracting the piston mouth, run into the scope of biopsy mouth broad, syringe injection port and biopsy mouth size mismatch, can make the eluant spill from the biopsy mouth, so will make the unable total collection of eluant, and this kind of collection operation can only the single scope pliers pipeline of washing, but the eluant of washing the scope pipeline is quantitative, lead to this kind of washing mode unable repetitious washing many times, each pipeline opening size of scope is not of uniform size, mismatch with the syringe mouth, consequently, can't adopt whole pipelines of scope, in addition, this kind of sampling mode eluant exposes in the external world, receive the pollution easily, also easy because the power is uneven, lead to the eluant to perfuse disconnected continuation, the above-mentioned reason leads to this kind of sampling mode can's accuracy to the internal mirror sampling, still need carry heavy peristaltic pump, the operation and carry all inconveniently.

In the second method, 50mL of eluent is extracted by a sterile syringe, injected from a biopsy port and used for flushing an endoscope pipeline, and the eluent is directly collected at the tip of the endoscope by a sterile bottle. The method has the advantages that the method has the defects of liquid leakage, incapability of collecting all pipelines, discontinuous sampling and filling and sampling pollution problems, and repeated washing links are carried out for many times, so that washed eluent is required to be pumped out from a liquid collecting bottle for collecting samples by using a sterile syringe, and the pipelines of the endoscope are washed again.

The third method, with washing-scrubbing-washing method, use aseptic inspirator to draw 20mL eluant and wash the pipeline of the pinchers through the biopsy port, collect the liquid in the aseptic bottle, insert the pipeline brush into the biopsy port, when the brush is inserted about 3 inches, collect the liquid flowing out in the anterior endoscope front end, continue pushing the brush into the pipeline, after the brush head appears in the anterior endoscope front end, cut the whole brush head of the section with the aseptic, put in the aseptic bottle, the surplus of the brush is drawn out from the biopsy port, repeat the above washing and scrubbing step, this method except that the liquid leakage, can't collect all pipelines, sample and pour into the incontinuous and have disadvantage of the pollution problem of sampling, the pipeline brush after sampling is apt to adhere to the microorganism, is not suitable for the colony counting, can't assess endoscope cleaning, sterilize effects accurately.

The sampling of the stain amount needs to collect the whole amount of the eluent, the less and more accurate the loss, the less and more accurate the pollution, the sampling operation also needs to wash and collect all the pipelines of the detected endoscope, the repeated washing is also needed, the sampling pollution needs to be reduced as much as possible, and the continuity of the eluent for filling and eluting the pipelines is ensured simultaneously so as to achieve the best elution effect, which is difficult to realize the conditions simultaneously by the current sampling mode and equipment.

The pipeline sampling of scope needs to collect the eluant by the wholeness, when carrying out the bacterial colony count, the eluant is lost less more accurate, sampling operation also need be washed the collection by whole pipelines that are detected the scope, still need wash many times repeatedly, the disappearance of any position sampling link, scope washing has all been underestimated to the meeting, the disinfection, sterilization effect, can lead to infecting the incident to take place, still should reduce to receive external pollution in the sampling process simultaneously, thereby reduce the pollution fungus and wash the interior mirror pipeline, the disinfection, sterilization effect produces the interference, still be suitable for the pipeline of the scope of multiple different grade type and model simultaneously, can present sampling mode and equipment hardly accomplish above-mentioned condition simultaneously, consequently need a kind of easy operation, the higher device of accuracy, come to seal and accomplish the sampling to the interior mirror pipeline.

Based on this, the utility model designs a contamination volume sampling device of scope internal pipeline to solve above-mentioned problem.
