Automatic dosing tank of ethylene oxide sterilization cabinet

Abstract

The invention belongs to the technical field of automatic dosing tanks of ethylene oxide sterilization cabinets, relates to a dosing tank of an ethylene oxide sterilization cabinet, and in particularrelates to an ethylene oxide tank capable of achieving automatic dosing and cyclic filling utilization. In order to improve the dosing efficiency and safety of an ethylene oxide sterilization cabinet,the invention provides an automatic dosing tank of an ethylene oxide sterilization cabinet; and the automatic dosing tank is characterized in that: automatic dosing and cyclic filling utilization canbe achieved; and furthermore, all ethylene oxide sterilization cabinets can be used as ethylene oxide sterilization tanks after being slightly refitted. The technical scheme adopted for solving the technical problems in the invention is as follows: firm and safe stainless steel is adopted as a tank body; furthermore, the corresponding volume of the tank body of the ethylene oxide tank is designedaccording to different specifications of ethylene oxide sterilization cabinets; two corresponding valves are arranged on the tank; and each valve is provided with a female head of a self-locking quick connector.

Description

[0001] Technical field [0002] The patent of the present invention relates to a drug delivery tank for an ethylene oxide sterilizer, especially an ethylene oxide drug tank that can be used for automatic drug delivery and recycling. Background technique [0003] Ethylene oxide is a broad-spectrum sterilizing agent that can kill various microorganisms at room temperature, and can penetrate the packaging of medical devices. Therefore, it is widely used as a sterilizing agent for medical devices. Ethylene oxide sterilization needs to use a professional ethylene oxide sterilizer. During sterilization, ethylene oxide needs to be vaporized and put into the sterilizer. The ethylene oxide sterilization concentration should be 600mg / l~ 800mg / l, the dosage of sterilizers with the same volume is basically constant, therefore, the dosage of ethylene oxide in each sterilizer is basically determined by the standard volume of the sterilizer, that is, ethylene oxide The dosage of alkane ster...

AI Technical Summary

Problems solved by technology

Because the ethylene oxide sterilizer needs to vaporize ethylene oxide to the sterilizer, and each time it takes at least ten minutes or more to do the vaporization, the larger the sterilizer, the greater the dosage. The longer the vaporization time, the longer the dosing process. During such a long dosing process, the dosing person must pay close attention to the dosing process, otherwise a little carelessness will cause incomplete vaporization of ethylene oxide and cause the ethylene oxide liquid to flow into the sterilization cabinet and pollute it. Sterilized items, or cause insufficient or excessive dosage

There are also a small number of relatively advanced small ethylene oxide sterilizers that use disposable ethylene oxide tanks for automatic dosing. This kind of medicine tank uses acupuncture for automatic dosing. Moreover, this kind of medicine can must be used in a sterilizing cabinet, and it is inconvenient to take and place. Moreover, the medicine can is made of aluminum alloy like a pop can, which is afraid of being squeezed, dropped, and pressed. It is not convenient and safe, so this kind of medicine tank can only be made into a small tank, which cannot be used in large and medium-sized ethylene oxide sterilization cabinets.
