Embodiment Construction

[0016] see Figure 1-2 , the endoscope in this implementation case is provided with a functional interface, and the functional interface includes a suction interface 1, a water spray interface 2, a suction valve 3, a water injection / air valve 4, a biopsy valve 5 or / and a nozzle 6 arranged on the endoscope. In this implementation case, the cleaning and sampling endoscope steps are as follows:

[0017] There are corresponding functional interfaces on the endoscope, reserve any two functional interfaces on the endoscope, block other functional interfaces of the endoscope, inject eluent into the endoscope from any of the reserved functional interfaces, and pass positive pressure Or the negative pressure drives the eluent to flow out from another reserved functional interface of the endoscope and collect it.

[0018] An eluent sampling pipeline 7 is connected to another reserved functional interface of the endoscope, and a negative pressure generator 8 is provided on the sampling ...

Abstract

A microbe sampling method for a medical soft endoscope is disclosed. The endoscope is provided with corresponding functional connectors, as an improvement, any two functional connectors on the endoscope are reserved, other functional connectors of the endoscope are blocked, an eluent is injected into the endoscope from any reserved functional connector, and is driven by positive or negative pressure to flow out from another reserved functional connector of the endoscope, and the eluant is then collected. According to the method, any two functional connectors on the endoscope are reserved, other functional connectors of the endoscope are blocked, the eluent is injected into the endoscope from any reserved functional connector, and is driven by positive or negative pressure to flow out fromanother reserved functional connector of the endoscope, and the eluant is then collected. Beneficial effects of the method are that the method can achieve completely enclosed microbe elution of the endoscope, the exchange of substances inside and outside is effectively avoided in a sampling process, the inside of the endoscope or a sample liquid is protected from being contaminated by exogenous substances, the flow speed of the eluant can be adjusted through a pump in the sampling process and the elution efficiency is increased.

Description

technical field [0001] The invention relates to a microbial sampling method of a medical flexible endoscope. Background technique [0002] Endoscope is an auxiliary medical detection device used to enter the body through the oral cavity or other natural orifices and observe suspicious lesions. The endoscope can be used to see lesions that cannot be seen on X-rays, such as foreign bodies, ulcers or tumors. Since the device needs to contact human mucous membranes and may cooperate with medical devices for other surgical operations, microbiological testing is required to avoid infecting patients. [0003] The conventional method is to hold the endoscope vertically, take a syringe and inject the eluent into the biopsy port, recover the eluate into the container, and then process the eluate by membrane filtration or direct inoculation. In this method, the liquid is recovered by gravity, the microbial elution rate is low, and the liquid and the container are completely exposed t...
