Full-automatic sample micropipette device for aerosol collection instrument

Abstract

The invention discloses a full-automatic sample micropipette device for an aerosol collection instrument, which is additionally provided with liquid replacement, cleaning and liquid supplementation units, and can automatically perform liquid replacement, cleaning and liquid supplementation on a sample bottle. Aiming at a connection problem between a biological aerosol collection instrument and biological detection equipment after sampling, the device establishes a rapid micro-pipetting, liquid replacement, cleaning and liquid supplementation system for a downstream sample of a liquid phase microbial sampler through an innovative design, and a complete process can be completed in 45 seconds. The system can make microbial aerosol collection and detection equipment unattended to be more suitable for large-scale gatherings, key personnel flow logistics sites, and the like. The device satisfies the monitoring capability of biological counter-terrorism microbial aerosol in strategic locations, as well as technical needs for performing full-automatic infectious environment microbial aerosol monitoring on densely populated areas such as in-hospital infection, animal culturing farms, port entry and exit halls, and transportation means.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to an automatic sample micropipetting device for an aerosol collector capable of fully automatic micropipetting, automatic cleaning and fluid replacement. Background technique [0002] Most of the diseases transmitted in the indoor environment are related to bioaerosols. Common sources of indoor bioaerosol pollution include sneezing behavior of humans and animals, as well as air pollution from outdoors. These pollution sources can produce respiratory pathogens, dust mites and their fragmentation products, molds , fungal spores, hyphae, and mycotoxins and other biological particles, these particles can enter the human body through the respiratory tract to cause infections, allergies and other reactions. [0003] In addition to the above-mentioned biological aerosols such as fungi and bacteria that are common in indoor and outdoor environments, in recent years, new outbreaks of cross-bord...

Problems solved by technology

[0005] However, after the existing bioaerosol sampling is completed, it is necessary to manually transfer the sample in a small amount and manually complete the biological detection sample addition, cleaning and rehydration process

This process is time-consuming, inefficient, and requires manual real-time monitoring

At present, micropipettes on the market are mostly used in nucleic acid automatic workstations, which are usually suitable for large-scale sample processing. Although the plunger pump can be used to inject the liquid storage tank from the sample bottle; however, the sample bottle needs to be replaced manually; the processing speed is slow , the pipetting process alone takes more than 2 minutes, which is difficult to meet the working requirements of the rapid detection of follow-up samples of the automatic processing bioaerosol collector
