Description

A degassing unit for transportation is deposited to biological sample

Technical Field

The utility model relates to a disinfection device for storing and transporting biological samples, which comprises a box body and an upper cover arranged at the top of the box body.

Background

The new coronavirus epidemic in 2019 brings great public health safety, and people in all the world pay attention to the new coronavirus, including professionals all have an effort to reach the new coronavirus, and epidemic prevention and control work is done seriously according to the requirements of the state. The work of epidemic prevention and control of infectious diseases is highly professional, and each link is related to the risk of the epidemic, wherein, biological safety including storage and transportation of biological samples (biological samples of infectious patients such as nasopharyngeal swabs and blood samples) and samples of vector organisms such as mosquitoes, ticks and the like are very important links. These high risk biological samples present a risk of leakage or spread of pathogens. Therefore, in addition to personal protection, carriers (sample transport boxes) for storing and transporting biological samples should be designed appropriately to minimize the risk of the sample storage and transportation process.

The existing biological transport case needs to be wiped and disinfected by a sample receiver with a chemical disinfectant after use, and is influenced by various factors in actual operation, such as whether the disinfection method of the sample receiver is correct, whether the disinfection program is standard, whether the quality of a disinfectant is correct, and the like. If each link has problems, the disinfection is not thorough, the risk of pathogen residue and leakage can be caused, biological safety accidents can be caused, and greater harm can be brought. Meanwhile, the chemical disinfectant is often used for disinfecting the transport case, so that the surface of the transport case is corroded, the service life is shortened, the smooth surface becomes uneven, a good carrier environment is provided for pathogen breeding, and the transport case is not easy to clean and disinfect.

Ultraviolet disinfection and sterilization are an old and effective method. For example, the quilt sunned under the sun is the most original method for removing mites, disinfecting and sterilizing by using ultraviolet rays. The principle of ultraviolet disinfection and sterilization is to use high-energy ultraviolet light to break double helix chains of DNA, thereby achieving the inactivation of bacteria and viruses. Compared with chemical sterilization and disinfection, the ultraviolet ray has the advantages of high sterilization efficiency, inactivation generally completed within a few seconds, and no other chemical pollutants. Because of convenient operation, the ultraviolet sterilizing lamp is suitable for all spaces, is an important sterilizing and disinfecting device in the fields of medical and health institutions in the first line and infectious disease epidemic situation treatment.

Taking the novel coronavirus pneumonia as an example, medical institutions in various places have great demands on ultraviolet lamps. These professional ultraviolet degerming lamps and lanterns can not only eliminate the indoor virus of hospital, can also alleviate nurse's daily disinfection work to a great extent, let nurses leave more time to take care of patient.

The ultraviolet lamp is not only in hospitals, but also can inactivate microorganisms. The family accessible installation ultraviolet water purification system purifies the water, and the air purifier who is furnished with the ultraviolet lamp can carry out innocent treatment to the bacterium that floats in the air, and application range including public place etc. is more extensive.

The ultraviolet light can achieve effective sterilization and disinfection to meet certain requirements, including the wavelength, the irradiation dose and the time of the ultraviolet light source. Namely, the ultraviolet light with the wavelength below 280nm in the UVC wave band is needed, and the irradiation dose and time are required to meet different bacteria and viruses, otherwise, the inactivation cannot be realized.

The ultraviolet rays are divided according to the wavelength, and the ultraviolet wave band can be divided into different UVA, UVB and UVC wave bands. UVC is a band of the shortest wavelength and the highest energy, and indeed the most effective for disinfection is UVC, a band known as deep ultraviolet.

At present, most of deep ultraviolet light sources applied to disinfection and sterilization in the civil and industrial fields are mercury lamps. Because of the great influence of mercury on human society and environment, the international water guarantee for restricting mercury use and emission officially became effective since this year, and the traditional mercury lamp will restrict, prohibit production and use, and gradually quit the market. Developing a brand-new environment-friendly and efficient ultraviolet light source becomes an important challenge in front of people. Deep ultraviolet LEDs based on gallium nitride wide bandgap semiconductor materials have become the second choice for this new application. The all-solid-state light source has small volume, high efficiency and long service life, and can emit ultraviolet light stronger than that of a mercury lamp only by a chip module with the size of a thumb cover.

The application of the deep ultraviolet LED to replace the traditional mercury lamp is similar to the application of the white light LED to replace the traditional light source to the illumination field in the disinfection and sterilization, and the deep ultraviolet LED is a new direction for future development.

In the new crown pneumonia epidemic situation, people pay high attention to ultraviolet deep ultraviolet LEDs, and particularly the public health safety of people is concerned. From the current application, the deep ultraviolet LED is widely applied to civil fields such as water purification, air purification, biological detection and the like. With the implementation of the Water guarantee convention, it is marked that the use of mercury-containing UV lamps is prohibited in 2020, so how to develop a new environment-friendly and efficient UV light source becomes an important challenge for people.

Deep ultraviolet light emitting diodes (DUV LEDs) based on wide bandgap semiconductor materials (GaN, AlGaN) are the second choice for this new application.
