Description

Preservation device for prolonging use validity of ethylene oxide reference substance Technical Field The utility model relates to the technical field of ethylene oxide laboratory storage equipment, in particular to a preservation device for prolonging the service life of an ethylene oxide reference substance. Background The current medical instruments adopt ethylene oxide sterilization, the ethylene oxide belongs to high toxic substances, the allowable amount in the air is 100PPM, the inhaled ethylene oxide can cause anesthesia poisoning and is extremely easy to be absorbed by blood, and the multi-organ damage of animals and people mainly including respiratory systems and nervous systems can be caused, so that most medical instruments after the ethylene oxide sterilization need to be subjected to ethylene oxide residual amount detection. The boiling point of the ethylene oxide is 10.7 ℃, and the ethylene oxide is greatly influenced by the ambient temperature and is extremely volatile, so that the opening validity period of the used ethylene oxide reference substance is the opening date, and the ethylene oxide reference substance cannot be reused every other day if the ethylene oxide reference substance is not used. The prior art has at least the following problems that the current domestic ethylene oxide reference substance is worse than the imported ethylene oxide reference substance, the imported ethylene oxide reference substance is high in price, only one group or a plurality of groups of linear solutions are used at each time, a large amount of remaining reference substance can be wasted, the linear solutions are required to be prepared at each time, and the operation efficiency is low. Disclosure of utility model Aiming at the defects of the prior art, the preservation device for prolonging the use validity of the ethylene oxide reference substance is developed, the ethylene oxide reference substance can be conveniently taken, volatilization can be reduced, waste is reduced, and the preservation effect of the ethylene oxide reference substance is effectively improved. The technical scheme includes that the preservation device for prolonging the use validity of the ethylene oxide reference substance comprises a containing bottle, a cooling base, a top cover, a liquid taking pipe, a sealing cover and a slot, wherein the top cover is arranged at the top of the containing bottle, the liquid taking pipe is arranged at the bottom of the top cover, the sealing cover is arranged at the top of the liquid taking pipe, the slot is arranged at the top of the cooling base, and the containing bottle is arranged in the slot. Preferably, the bottom of the containing bottle is high at the periphery and low at the center. Can conveniently gather the ethylene oxide reference substance and avoid waste. As optimization, the liquid taking pipe is a conical pipe, and the diameter of the top of the liquid taking pipe is larger than that of the bottom. The convenient pipettor that inserts reduces the area of contact of ethylene oxide reference substance and external world. As optimization, the inside of cooling base is equipped with holds the chamber, and cooling base's top is equipped with the filling mouth that holds the chamber intercommunication, is equipped with the plugging cap on the filling mouth.
