Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to a sample storage device. Background Art

[0002] Biological samples are important resources for medical research, and their quality largely determines the accuracy and reliability of clinical results. At present, biological samples and their extracted products are mainly stored in two ways: deep cryogenic and room temperature. In response to the needs of different scientific research, more sample storage methods have been introduced. However, most samples need to be stored in a centralized manner after sampling. Most existing samples are stored in storage cabinets. After the storage cabinet is opened, air will enter the storage cabinet. Dust and bacteria in the air will contact the sample container for a long time, which will cause sample contamination. In addition, the anti-infection ability of the storage cabinet is weak, and it is inconvenient to directly sterilize the inside of the storage device.

[0003] Therefore, there is an urgent need for a sample storage device with a sterilization function, which can sterilize the contamination sources that may contaminate the sample, so as to reduce the possibility of sample contamination. Utility Model Content

[0004] The utility model aims to provide a sample storage device, which mainly stores samples in a sterilization chamber. The sterilization chamber can be placed in a low-temperature storage tank or used alone according to whether the samples need to be stored at low temperatures. At the same time, the sterilization chamber adopts a modular design so that it can be used in combination according to the number of samples to be stored. In addition, ozone sterilization technology is combined to disinfect the pollution sources that may contaminate the samples in the sterilization tank, thereby reducing the possibility of sample contamination.

[0005] In order to achieve the above technical effects, the utility model is implemented through the following technical solutions: a sample storage device, including an ozone generator, a low-temperature booster, a low-temperature storage tank and a sterilization chamber; characterized in that: the ozone generator pipeline is connected to the upper end of the sterilization chamber; the sterilization chamber is disassembled and installed inside the low-temperature storage tank, including a bottom chamber, a plurality of intermediate chambers disassembled and connected to the bottom chamber, and a hatch cover disassembled and connected to the intermediate chamber; the low-temperature booster pipeline is connected to the low-temperature storage tank.

[0006] Furthermore, the side wall of the bottom cabin is provided with an exhaust hole, and the upper surface of the cabin cover is provided with a handle and an air inlet hole connected to the ozone generator through a pipeline.

[0007] Furthermore, a plurality of sample grids are provided inside the bottom compartment and each intermediate compartment, and positioning molds matching with the sample containers are provided inside the sample grids.

[0008] Furthermore, the positioning mold is made of a material with good buffering and anti-collision effects.

[0009] Furthermore, the ozone generator and the low-temperature supercharger are both electrically connected to a power supply device.

[0010] Beneficial effects of the utility model:

[0011] 1) The utility model connects the sterilization chamber pipeline to the ozone generator to achieve the disinfection of pollution sources around the sample storage environment, thereby reducing the possibility of sample contamination;

[0012] 2) The utility model places the sample in a sample container and places it in a sterilization chamber, so that the sterilization chamber can be used in combination with a low-temperature storage tank to achieve low-temperature storage of the sample, and can also be used independently to meet the requirements of room-temperature storage of the sample;

[0013] 3) The utility model realizes modularization of the sterilization cabin by designing the sterilization cabin to be composed of a bottom cabin, a cabin cover and a plurality of intermediate cabins, and can meet the demand when the number of sample storage changes by combining different numbers of intermediate cabins.
