Problems solved by technology

[0003] During the pre-cultivation process, we found that there is a great safety hazard in the breaking work, that is, there is a great danger in breaking the glass ampoule in the biological indicator.
Because the outer material of the spore tube is mostly made of soft plastic products, there is no special crushing device for crushing, and it is difficult to avoid the risk of crushing by hand and causing the glass ampoule in the biological indicator to penetrate the plastic product, or use other non-special foreign objects to force Caused problems such as backflow of culture medium in spore tubes
Due to the small size of the spore tube with a diameter of about 5mm, it is not conducive to standing upright and easy to dump. However, the cultivation temperature of Bacillus stearothermophilus currently used for biological indicators, especially high-pressure steam sterilization, is relatively high, and there are indicators such as spores. Biosafety hazards caused by upside-down leakage of tubes, etc.

Abstract

The invention discloses a biological indicator assisted crushing and culturing device. The device comprises a culture box, a mounting frame and a crusher, wherein the culture box is a colorless and transparent box, the mounting frame is arranged above the culture box, multiple biological indicator storage units are arranged in the mounting frame, and one side of the culture box is connected with acrusher connecting part connected with the crusher detachably. The device can effectively assist crushing of biological indicators, solve the problem of hand pricking or culture medium backflow, assist culture of the biological indicators and avoid biological safety harm caused by inversion leakage of a spore tube. The invention further discloses a use method of the biological indicator assistedcrushing and culturing device.

Description

technical field [0001] The invention relates to the field of sterilization detection, in particular to a biological indicator assisted crushing culture device and a use method thereof. Background technique [0002] The Bacillus biological indicator can be used to monitor the effect of high and low temperature disinfection, and the pressure steam sterilization biological culture indicator is used to monitor the effect of pressure steam sterilization: the sterilization effect of exhaust pressure steam at 121°C and pre-vacuum pressure steam at 132°C Monitoring (including lower exhaust pot and pre-vacuum pot); low-temperature biological culture indicator can be used for the monitoring of sterilization effects such as plasma furnace and ethylene oxide disinfection, by breaking the glass ampoule containing the indicator in the biological indicator and After the bacillus on the paper is contacted, it is placed in an incubator at the desired temperature for cultivation at the same t...
