Fast sterilization device for sterile operation inoculation instruments and use method thereof

Abstract

The invention discloses a fast sterilization device for sterile operation inoculation instruments. The fast sterilization device comprises a power control system arranged in an upper shell and an electromagnetic induction system arranged in a lower shell, wherein the upper shell and the lower shell are connected and fixed by connecting columns; the electromagnetic induction system comprises a ceramic cylinder, an induction coil and a temperature sensor; the inner part of the ceramic cylinder is used for placing the instruments to be sterilized, the induction coil wound at the periphery of theceramic cylinder and the temperature sensor is arranged in the ceramic cylinder; the power control system comprises a power supply, a controller, a high-voltage driving plate, a voltage-reducing module and a relay group; the temperature sensor is electrically connected with the controller; the negative electrode of the high-voltage driving plate is connected with the negative electrode of the power supply, and the positive electrode of the high-voltage driving plate is connected on the relay group; the relay group is connected with the positive electrode of the voltage-reducing module and is electrically connected with the controller. The fast sterilization device for the sterile operation inoculation instruments and a use method thereof have the beneficial effects that the working efficiency can be improved, the types of the inoculation instruments to be sterilized are expanded, a part of instruments are prevented from being damaged, the energy consumption can be reduced and the safeproduction is achieved.

Problems solved by technology

[0003] Twenty years ago, alcohol lamp flame heating was used to sterilize and sterilize. This method has a thorough disinfection effect and low cost, but the biggest defect is that there is a great potential safety hazard. Fire problems caused by alcohol lamps often occur in laboratories.

In the past ten years, we have gradually seen sterilization devices that replace alcohol lamps. For example, the patent number is CN200620080704.5, and the patent name is "Quick disinfection device for aseptic operation inoculation equipment". The principle is based on radiation-focused heating and has the characteristics of rapid temperature rise. , but the self-generating heat of the equipment is high, the energy consumption is too high, and the line is under great pressure, so there are still certain safety hazards; the patent number is CN200920115225.6, and the patent name is "a sterilizer for tissue culture and inoculation equipment". Heating conducts heat through ceramic containers and quartz sand to realize high-temperature sterilization of inoculation instruments; the heating principle of the JZ-2 digital display (JZ-1 knob type) inoculation instrument sterilizer commonly used in tissue culture production today is also resistance wire heating High-temperature sterilization of inoculation utensils through heat conduction through ceramic containers and quartz sand

Quartz sand has the effect of heat preservation, but because the quartz sand in the ceramic container is closely arranged, huge resistance and friction will be generated during the insertion process of the appliance, especially it will cause serious damage to the sharp and thin scalpel blade, and the heating speed of the equipment is slow , it takes about 20 minutes to reach the preset temperature above 260°C after the power switch of the equipment is turned on, and the work efficiency is low

Secondly, the temperature of the ceramic container itself reaches 260°C, which will bring a lot of radiant heat to the equipment shell, which is easy to burn the operator and cause high temperature in the working environment

In short, all the above sterilization methods: alcohol lamp flame method, resistance wire heating, fire roasting, infrared lamp roasting, etc. all have the ability to reach a certain high temperature first, and then drive the inoculation device to heat up to achieve the sterilization effect Defects such as high consumption, low thermal efficiency, and insufficient safety
