Apparatus for collecting protection type pathogenic sample of infection department

Abstract

The invention discloses an apparatus for collecting a protection type pathogenic sample of an infection department, comprising a collection straw. A balloon sleeve is arranged on one side of the collection straw, the balloon sleeve is matched and connected with the collection straw through an annular sealing groove arranged at a corresponding position of the collection straw. Annular sealing gaskets are arranged at inner and outer sides of the balloon sleeve close to the collection straw, anti-slip grooves evenly distributed at equal angles are arranged on an outer side of one end of the collection straw close to the balloon sleeve. A balloon is arranged on one side of the balloon sleeve far away from the collection straw, a sample collecting pipe is arranged at an inner middle position ofthe balloon sleeve. The problem of leakage in the collecting process can be solved by a tapered flow guiding pipe arranged in the middle part of the collection straw. Sample collection is facilitatedby a flow guiding column arranged on one end of the tapered flow guiding pipe. The balloon sleeve and the collection straw are sealed connected through the annular sealing groove and the annular sealing gasket, so that pathogens can be prevented from being emitted into the air, and the operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a protective pathogen sample collection device for the Department of Infectious Diseases. Background technique [0002] Infectious diseases are due to the poor ability of the patient to inhale and resist viruses during the treatment period, and contract other diseases. Therefore, the collection of pathogenic samples of infectious diseases is very important. The existing pathogenic sample collection devices cannot solve the problem during the collection process. It is not convenient to collect samples. For example, the patent application publication number 201710619796.2 discloses a protective pathogen sample collection device for the Department of Infectious Diseases, including a sampling tube and a sample retention tube. The side of the sampling tube is provided with an air guide tube. , the opening direction of the air guide tube in the sampling tube is upward, one end ...

Problems solved by technology

[0002] Infectious diseases are due to the poor ability of the patient to inhale and resist viruses during the treatment period, and contract other diseases. Therefore, the collection of pathogenic samples of infectious diseases is very important. The existing pathogenic sample collection devices cannot solve the problem during the collection process. It is not convenient to collect samples. For example, the patent application publication number 201710619796.2 discloses a protective pathogen sample collection device for the Department of Infectious Diseases, including a sampling tube and a sample retention tube. The side of the sampling tube is provided with an air guide tube. , the opening direction of the air guide tube in the sampling tube is upward, one end of the air guide tube is provided with an air bag, one end of the sampling tube is connected to the guide tube through a first rubber stopper, and the end of the sampling tube extends into the guide tube. The inside is sealed with the first rubber stopper, and the catheter extends into the bottom of the sample retention tube, but the above patents cannot solve the leakage problem during the collection process, which is inconvenient to collect samples and inconvenient to use
