Sampling device for severe-case enterovirus 71 infection sample and sampling method of severe-case enterovirus 71 infection sample

Abstract

The invention belongs to the technical field of medical auxiliary appliances, and discloses a sampling device for a severe-case enterovirus 71 infection sample and a sampling method of the severe-case enterovirus 71 infection sample. The sampling device comprises a sampling device body, a sampling hole is formed in the outer wall of the sampling device body, a rotatable installing plate is arranged inside the sampling device body, the installing plate is positioned above the sampling hole, at least one sampling assembly is fixed on one side of the installing plate, and the sampling assemblies annularly move around the central axis of the sampling device body when the installing plate rotates, and can communicate and matches with the sampling hole in the moving process. In conclusion, when the sampling assemblies rotate to correspond to the sampling hole of the shell, automatic sampling can be completed under the preset negative pressure condition, and the corresponding sampling assembly can achieve automatic sealing operation after the sampling, so that a sampled sample is effectively prevented from being polluted, and the sampling result is more accurate.

Description

technical field [0001] The invention belongs to the technical field of medical aids, and in particular relates to a sample sampling device for severe enterovirus 71 infection and a sampling method thereof. Background technique [0002] Enterovirus type 71 (EV71) is one of the most important pathogens causing hand, foot and mouth disease; hand, foot and mouth disease seriously threatens the health of preschool children, with strong infectivity and high morbidity, especially involving the nervous system Among them, children with severe disease progress rapidly and may even have frequent convulsions, coma, brain herniation, dyspnea, shock and other circulatory insufficiency problems. Specifically, in the clinical treatment of hand, foot and mouth disease, in order to ensure the accuracy of disease diagnosis, it is necessary to perform corresponding sampling operations in the patient's mouth and throat. [0003] At present, the serological detection of EV71 is prone to cross-im...

AI Technical Summary

Problems solved by technology

[0003] At present, the serological detection of EV71 is prone to cross-immunity with other hand, foot and mouth diseases, and the duration of detectable EV71-specific IgM antibodies after infection is uncertain; in the prior art, the commonly used sampling method is to use throat swab Dip samples directly in the patient's mouth and throat

However, this sampling method requires the patient to keep the mouth open for a long time during actual operation, and when the throat swab is inserted into the patient's throat, because the throat is relatively sensitive, it will cause greater discomfort to the patient. Problems of poor fit and difficult sampling

In addition, traditional throat swabs are completely exposed to the air during sampling, which can easily cause sample contamination and affect the accuracy of sampling testing
