Portable avian influenza virus detection sample collection device

Abstract

The invention relates to a portable avian influenza virus detection sample collection device, which is characterized in that the middle of an upper clamping plate is hinged to the middle of a lower clamping plate, an upper mouth hook mechanism and a lower mouth hook mechanism which are matched with each other are arranged on the upper clamping plate and the lower clamping plate, and a sampling mechanism is slidably arranged in a mounting mechanism; and the sampling mechanism is in transmission connection with the upper mouth hook mechanism and the lower mouth hook mechanism through a pull rod mechanism. A duckbill is arranged between the upper mouth hook mechanism and the lower mouth hook mechanism in a penetrating mode, and the duckbill can be opened and stably clamped through cooperation between the upper mouth hook mechanism and the lower mouth hook mechanism. Meanwhile, the sampling mechanism is released through the mounting mechanism, a cotton swab stored in the inclined storage tank can be released through the shifting rod connected with the upper pull rod, after the end of the cotton swab makes contact with liquid in the oral cavity of a duck, avian influenza virus detection samples are collected, and sampling personnel take down the cotton swab and then collect the cotton swab into the collecting box for standby application. According to the device, duckbilled opening and stable clamping are achieved, meanwhile, automatic sampling can be achieved, the workload of sampling personnel is reduced, and the sampling risk is reduced.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of virus detection auxiliary equipment, in particular to a portable avian influenza virus detection sample collection device. Background technique [0002] Avian influenza virus (AIV) belongs to the influenza A virus of the genus Influenza virus. According to the pathogenicity of AIV to poultry, it can be divided into three levels of high, medium and low pathogenicity AIV. Influenza A virus mostly occurs in birds, but because AIV is prone to gene mutation or recombination during the replication process, the structure of the virus's hemagglutinin (HA) and neuraminidase (NA) changes, and it acquires the ability to infect humans . The AIV subtypes that have been found to be able to directly infect humans include: H5N1, H7N1, H7N2, H7N3, H7N7, H9N2 and H7N9 subtypes. Among them, the new AIV subtype H7N9, which was first discovered in humans in March 2013, is of particular concern. It ...

Problems solved by technology

However, the existing serum detection method is generally through syringe extraction, which is not only cumbersome but also requires a large number of syringes. Therefore, the detection price is relatively expensive; while the existing cotton swab method, if you want to dip the liquid in the oral cavity, you need to It is necessary to break the duckbill and dip it with a cotton swab in hand. At least two people are required to cooperate. Moreover, the neck of the duck is long, and the twisting of the neck is easy to come out of the sampler's hand during sampling, which affects the efficiency and effect of sampling.
