Isolation window for preventing and controlling cross infection of pharyngeal/nasal test sample

Abstract

The invention provides an isolation window for preventing and controlling cross infection of pharynx/nose test sample. The isolation window comprises a disinfection cavity, an induction window, an annular belt-shaped filter membrane, isolation cloth and an air suction pipe with an inlet covered by the filter membrane, the filter membrane longitudinally surrounds the air suction pipe and is supported and driven by a roller to circularly rotate and disinfect in the disinfection cavity, a detection channel is arranged under an inlet of the air suction pipe, the induction window is arranged above the front end of the detection channel, the induction window is located right in front of the inlet section of the air suction pipe, the isolation cloth covers the induction window, extends into the disinfection cavity, circularly rotates in a disinfection cabinet under supporting and driving of the roller and performs disinfection, and surrounds the inlet section of the air suction pipe in the horizontal direction, a disinfection cavity exhaust fan is arranged at the upper part of the disinfection cavity, and suction is used through a fan to keep the micro-negative pressure at a gap where the filter membrane and the isolation cloth enter the disinfection cavity. According to the isolation window, a head of an examinee can be accurately positioned, the sampling efficiency is high, gas exhaled by the examinee can be sucked out, filtered and disinfected in a short distance, disinfection is thorough, safety and reliability are achieved, and the isolation window is compact in structure.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to an isolation window for preventing and controlling cross-infection of pharyngeal / nasal test samples in the technical field of respiratory nucleic acid detection equipment. Background technique [0002] During the epidemic period of pneumonia, in order to effectively prevent and control, the country has formulated scientific and strict nucleic acid testing and sampling standards, but these standards and norms cannot prevent the tested person from taking off the mask, exposing the mouth and nose in front, and the gas exhaled by the tested person When the infectivity increases in a mixed atmospheric environment, there is an obvious risk of cross-infection in the process of nucleic acid testing for all residents. [0003] At the same time, although the medical staff carried out strict disinfection measures after sampling each tested person, the scope of disinfection was onl...

Problems solved by technology

[0006] In order to solve the problem that the gas exhaled by the previous subject is cross-infected to the subsequent medical staff and the subsequent subject when the "nose test" or "throat test" sample is collected during the nucleic acid detection process, the present invention provides An isolation window for preventing and controlling cross-infection of pharyngeal / nasal test samples. The technical idea of ​​the invention is to filter the exhaled gas of the subject through the filter membrane by suction, so that the pathogens are attached to the surface of the filter membrane or in the membrane pores, and then Let the filter membrane circulate and turn over, use the disinfection device to inactivate pathogens at the same time, and reuse the filter membrane, which solves the problem of directly disinfecting the exhaled gas of the subject. The inhaled gas to be sterilized is large in volume and high in energy consumption. Change the sterilized exhaled gas to a sterilized filter membrane. The filter membrane can rotate slowly, and there is no need to purify the filtered gas when sterilizing the filter membrane. It is safe and reliable, and does not need to store the filter. After the gas, the disinfection device required to disinfect the filter membrane is simple, only need ultraviolet radiation or formaldehyde soaking or high temperature disinfection
