Multifunctional biomedicine instrument

Abstract

The application discloses a multifunctional biomedicine instrument, comprising a working host machine, an ozone generator, a cover body and a bottom plate, wherein the working host machine comprises a substrate and a function cabin arranged at the substrate; the ozone generator is located in the substrate; the working host machine is placed on the bottom plate; the cover body is covered on the bottom plate to form a closed space; the substrate, the function cabin and the ozone generator are located in the closed space. Therefrom, the working host machine is placed in the closed space through the closed space formed by the cover body and the bottom plate, then the working host machine is disinfected by an ozone generator; the working host machine can perform the ozone disinfection before or after working every time, thereby preventing operation samples and working environments from being polluted; through matching with different function components, the working host machine can realize cryopreserved cell dry type recovery, constant temperature incubation of microorganism, stability temperature oscillation of a microwell plate, wane table shaking, metal bath, constant temperature incubation of a biological indicator, cell heat shock cultivation, and others.

Description

technical field [0001] The invention relates to a biomedical instrument, in particular to a multifunctional biomedical instrument capable of ozone disinfection. Background technique [0002] In the field of cell biology, liquid nitrogen freezing is an important way to preserve cell biological resources, that is, cells are frozen in a liquid nitrogen tank, and when the experiment requires, the frozen cells are taken out for recovery. When cells are resuscitated, the best operation is to quickly raise the temperature of the cell cryopreservation tube just taken out of the liquid nitrogen tank to 37°C, so that it can quickly pass through the most vulnerable cell temperature of -5-0°C, so as to avoid ice crystal recrystallization causing damage to the cells. damage, leading to cell death. [0003] In the current actual operation, the experimenter uses tweezers to hold 2 to 4 cell cryopreservation tubes, and thaws the cells quickly by shaking vigorously in an ordinary water bath...

AI Technical Summary

Problems solved by technology

[0003] In the current actual operation, the experimenter uses tweezers to pick up 2 to 4 cell cryopreservation tubes, and shakes the cells quickly in an ordinary water bath to quickly thaw the cells, but this conventional operation method is difficult to complete the recovery of a large number of cells; There are also companies that thaw multi-tube cells at the same time by adding a separate tray in the water bath; When using a water bath, it will inevitably cause the water temperature in this area to not reach 37°C for a long time. Compared with the traditional method of thawing single-tube cells, it prolongs the time for cell recovery, violates the principle of "slow freezing and quick thawing" of cells, and increases repetitions. Risk of crystallization, reduced cell viability

Resuscitating cells in a water bath also increases the possibility of cell contamination, which cannot meet the requirements for aseptic operation of the entire process of cell production, cryopreservation, and resuscitation

[0004] In addition, the traditional cell resuscitation still requires manual operation of the resuscitation process, which cannot guarantee the exact time of resuscitation; and cannot monitor the temperature change of the resuscitator in real time, and cannot guarantee the exact temperature of the resuscitation, and the traditional cell resuscitation instrument has a single function and cannot Can be disinfected by ozone, the sample is easily contaminated, and the use efficiency is low
