Microbe sampling enrichment culture tube

Abstract

The invention relates a microbe sampling enrichment culture tube. A sampling casing tube comprises a tube body and a cover, which are made of transparent hard plastic, wherein the upper end of the cover has a notch groove, so that the cover can be pulled open conveniently; a sealing ring is arranged at the lower end of the cover and consists of a sealing convex ring A and a sealing convex ring B; one side of each of the sealing convex rings A and B is a plane and the other end of each of the sealing convex rings A and B is circular arc-shaped; the tube body and the cover are sealed tightly; the liquid and odor in the tube body do not flow outside and pollute the environment; a solid hard plastic sampling rod (excrement sampling rod and swab rod) can be inserted into the cover; the cover and the sampling rod are arranged in a split manner, so when the sampling rod is pulled out, the sampling casing tube can be used alone; the sampling rod has steps serving as identifiers for the depth in the anus; the tail end of the sampling rod has a round head shaped liked a steamed bread, and three smooth excrement sampling rings are arranged at the position close to the round head; and the elliptic cylinder at the tail end of a virus and bacterial swab rod has nylon flocking. The microbe sampling enrichment culture tube is well sealed, so liquid and odor are prevented from coming out and environment protection is promoted; the thickness of the excrement sampling rod is so proper that a patient feels comfortable and has no pain; and the examination is visual, the carrying and operation are convenient, and the structure is simple.

Description

technical field [0001] The invention relates to a medical sampling device, in particular to a multifunctional, well-sealed, environmentally friendly, safe to operate and humanized microbial sampling enrichment and culture tube. Background technique [0002] At present, when collecting stools from bedridden patients in hospitals, the utensils commonly used are "anal swabs". The head is easy to fall off and is not easy to take out. In case there are burrs on the bamboo stick, it is easy to damage the intestinal tract and bring pain to the patient; Because all toilet collection devices are made of soft plastic, and the capacity of the tube body is small, the enrichment solution put in it is easy to overflow during transportation, polluting the surrounding environment, and the tube body is translucent and it is difficult to observe the cultured bacteria Status; when used for virus sampling, traditional swabs (such as cotton swabs, rayon swabs, polyester swabs) are mostly used, ...

[0002] At present, when collecting stools from bedridden patients in hospitals, the utensils commonly used are "anal swabs". The head is easy to fall off and is not easy to take out. In case there are burrs on the bamboo stick, it is easy to damage the intestinal tract and bring pain to the patient; Because all toilet collection devices are made of soft plastic, and the capacity of the tube body is small, the enrichment solution put in it is easy to overflow during transportation, polluting the surrounding environment, and the tube body is translucent and it is difficult to observe the cultured bacteria Status; when used for virus sampling, traditional swabs (such as cotton swabs, rayon swabs, polyester swabs) are mostly used, which are all produced by traditional "ear plug" technology, that is, winding thousands of meters of fiber At the top of the plastic stick, while the cotton swab is harmful to microorganisms, the man-made fiber wrapped swab has a low release ability to the collected microorganisms, and the release rate is only 30%

The hand-held part of the swab rod must be broken or cut artificially, the operation steps are cumbersome, and the chance of contamination is increased
