Technical Field

The utility model relates to the technical field of endoscope sampling, in particular to a device for sampling the bacteria infection amount of a duodenum mirror.

Background

Post-sterilization endoscopic sampling methods described in hospital sterilization sanitation standards (GB 15982-2012): taking a cleaned and sterilized endoscope, adopting a sterile injector to extract 50mL of eluent containing a corresponding neutralizing agent, injecting the eluent into a flushing endoscope pipeline from a biopsy port, collecting and checking the whole amount of the eluent for flushing the endoscope pipeline, judging that the cleaning, sterilizing and sterilizing are unqualified when the total number of microorganisms exceeds a certain standard, and cleaning, sterilizing and sterilizing again until the qualified detection result of the bacterial contamination sampling is usable, wherein a plurality of specialists commonly set a related standardized scheme for the duodenal endoscope sampling, the medical instrument such as the endoscope is widely used in a medical institution, strict cleaning, sterilizing and sterilizing are required before the use and before the use of a new endoscope, and a large class of biological groups including bacteria, viruses, fungi, some small protozoa and the like are required, and if the microorganisms enter a human body, the microorganisms possibly cause infection, the total number of the microorganisms on the endoscope is required to be sampled and detected before the use, the detection is called the bacterial contamination sampling and the bacterial contamination sampling, the defect of any sampling links can be underestimated, and the infection effect can be caused.

The endoscope structure includes: the endoscope comprises an insertion part, an operation part, a universal cable, an optical connector, a related accessory, a forceps pipeline, a suction pipeline, a secondary water supply pipeline, an air/water supply pipeline and the like, wherein the number of the pipelines in the endoscope of different types and models is greatly different, the pipelines are long and short, the pipe diameter is thick and thin, the front end part is positioned at the tail end of the insertion part, the relatively complex front end part of the endoscope is provided with an air/water supply nozzle, a forceps pipeline outlet, an objective lens, a light guide beam, a secondary water supply pipeline outlet and the like, and the structure of the endoscope is more complex, and the endoscope is different from the front end parts of other endoscopes, namely the endoscope is provided with a valve body and a connector.

At present, there are four methods for sampling the bacteria infection amount of an endoscope. In the first method, a tube is connected to the tip of an endoscope at the time of sampling, an eluent is extracted by a sterile syringe, an endoscope line is flushed through a biopsy port of an operation unit, and the eluent flowing out of the endoscope line is collected in a bottle by a peristaltic pump. When the endoscope with a very thin pipeline is used for injecting liquid from a biopsy port, the eluent flows out from the suction piston port due to overlarge force, when the endoscope with a wider biopsy port is used for injecting the eluent from the biopsy port, the size of the syringe injection port is not matched with that of the biopsy port, the eluent can leak out from the biopsy port, so that the eluent can not be collected in full quantity, the collecting operation can only flush the endoscope forceps pipeline once, but the eluent for flushing the endoscope pipeline is quantitative, so that the flushing mode can not be repeatedly flushed for many times, the opening sizes of all the pipelines of the endoscope are different and are not matched with the syringe port, therefore, all the pipelines of the endoscope can not be acquired, the tip of the duodenal endoscope can not be sampled, in addition, the eluent can be exposed outside easily and polluted easily due to uneven force, the intermittent perfusion of the eluent is easy, and the sampling mode can not accurately sample the endoscope, and a peristaltic pump with heaviness is required to be carried, and the operation and the carrying are inconvenient.

In the second method, 50mL of the eluent is withdrawn by a sterile syringe, injected into the irrigation endoscope line from the biopsy port, and collected directly from the tip of the endoscope by a sterile bottle. Besides the defects of liquid leakage, incapability of collecting all pipelines, incapability of collecting the front end part of the duodenoscope, incoherence in sampling and perfusion and sampling pollution problem, the method has the advantages that the repeated flushing links are repeated for a plurality of times, the flushed eluent is required to be pumped out of the liquid collecting bottle for collecting the sample by using a sterile injector, and the pipelines of the endoscope are flushed again.

In the third method, 20mL of eluent is extracted by a sterile injector through a biopsy port to flush a forceps pipeline, liquid is collected in a sterile bottle, a pipeline brush is inserted into the biopsy port, when the brush is inserted into the biopsy port, the liquid flowing out is collected at the front end of an endoscope, the brush is continuously pushed into the pipeline, after the front end of the endoscope appears, the whole brush head is cut by sterile scissors and placed in the sterile bottle, the rest part of the brush is extracted from the biopsy port, and the above flushing and brushing steps are repeated.

In a fourth method, a method for monitoring, sampling and culturing a duodenoscope, and a method for sampling the bacteria infection amount of the duodenoscope, wherein the sampling comprises a front end groove and a forceps pipeline and/or a light guide pipeline, the steps of flushing, brushing and flushing are carried out on the forceps pipeline in two stages, the front end groove is flushed and brushed, the forceps pipeline is sampled in the first stage, 20mL of sterile water is pumped by a sterile syringe, the forceps pipeline is flushed through a biopsy port, liquid is collected in a sterile bottle, a pipeline brush is inserted into the biopsy port, when the brush is inserted into the sterile bottle, the liquid flowing out from the front end of the endoscope is collected, the brush is continuously pushed into the pipeline, the brush head is sheared by the sterile cutter after the brush head appears at the front end of the endoscope, the brush head is placed in the sterile bottle, the rest part of the brush is pulled out from the biopsy port, the flushing and brushing steps are repeated, the front end groove in the second stage, when the front end part of the endoscope is sampled, 1mL of the sterile cutter is sucked by a sterile pipette, the sterile liquid is repeatedly sucked into the front end groove by the sterile cutter, the sterile cutter is sucked into the sterile bottle after the sterile cutter, the sterile cutter is repeatedly sucked into the sterile bottle, and the sterile cutter is sucked into the sterile bottle when the end of the sterile bottle is sucked into the sterile bottle, and the sterile bottle is simultaneously sucked into the sterile bottle. Filling 1mL of sterile water into an endoscope groove, filling the residual liquid in the groove and the liquid flowing out from the front end into a sterile bottle, lifting a forceps lifting device, repeating the actions for two times, soaking the sterile brush by the sterile water, brushing the groove by the brush, lifting the forceps lifting device, finally cutting off a brush head by sterile scissors, falling into the sterile bottle, repeating the steps by a new sterile liquid-transferring device, and finally collecting the sampling liquid and the brush head in two stages into one bottle for inspection.

The method has the advantages that the total amount of eluent is required to be collected in the process of sampling the bacterial contamination, the less and more accurate the loss is, the less and more accurate the pollution is, the sampling operation is also required to flush and collect all pipelines of the endoscope to be detected, the repeated flushing is also required, the sampling pollution is required to be reduced as much as possible, especially the sampling of the front end part of the duodenum endoscope is required to be sampled in a special mode, the aerosol diffusion generated in the sampling process of the front end part of the duodenum endoscope is also reduced, the structure of the front end part is damaged in the scrubbing operation is reduced, the cleaning, disinfecting and sterilizing effects of the endoscope are more accurately evaluated, the harm of the aerosol to sampling personnel is reduced, and the front end part is also reduced in the sampling operation, so that the current sampling mode and equipment are difficult to simultaneously achieve the conditions.

The cleaning, disinfection and sterilization are necessary, the general endoscope is cleaned, only flannelette, a cleaning brush or sponge is used for thoroughly brushing, all the outer surfaces of the endoscope are wiped, only the air supply and water supply nozzle openings and the objective lens at the front end of the insertion part are needed to be paid attention to, all the scraps on all the surfaces of the front end are confirmed to be wiped off, the pipeline is flushed during sampling, the eluent flows out from the front end, the sampling of the front end of the corresponding pipeline can be synchronously completed, and finally the front end is simply flushed through the eluent, so that the general endoscope can be sampled.

The structure of the front end part of the duodenoscope is complex, and has cleaning, disinfection and sterilization blind areas, and the cleaning needs fine brushing. Other endoscopes have simple structures and are easy to clean, disinfect and sterilize without fine brushing, so that the front end part of the duodenum endoscope needs a special sampling mode for sampling, and the sampling is completely different from the sampling of the front end part of other endoscopes, and when the front end part of the duodenum endoscope is cleaned: the protective cap of the tip part is required to be detached from the tip part to enable the tip part to be completely exposed, then the endoscope is soaked in washing liquid, all the outer surfaces of the endoscope are thoroughly brushed or wiped by a soft brush or flannelette, particularly, air supply and water supply nozzle openings are carefully carried out, all the surfaces of the tip part are thoroughly cleaned in place, the soft brush is used for brushing pliers guide wires and pliers pipeline opening grooves, the positions of the pliers lifting device are adjusted, the two sides of the pliers lifting device, the inner grooves of the pliers lifting device and the periphery of the middle shaft of the pliers lifting device are brushed, the other positions of the tip part are respectively inserted into the pliers pipeline openings of the tip part, then the pliers pipeline is pulled out, and other types of endoscope tip parts are brushed in a simple structure without the need of complex cleaning modes.

The method is characterized in that the whole eluent is required to be collected in the pipeline sampling and the front end sampling of the endoscope, when colony counting is carried out, the less and more accurate eluent is lost, the sampling operation is also required to flush and collect all the pipelines of the endoscope to be detected, and the repeated flushing is also required, especially the duodenum endoscope, the front end sampling is required to be carried out in a special mode, the cleaning, disinfection and sterilization effects of the endoscope are underestimated due to the absence of any sampling links, the infection event is possibly caused, the aerosol diffusion generated in the process of sampling the front end of the duodenum endoscope is also reduced, the structure of the front end is damaged by scrubbing operation is reduced, the cleaning, disinfection and sterilization effects of the endoscope are accurately estimated, the harm of the aerosol to sampling personnel is reduced, and the front end is also required to be damaged by the sampling operation.
