Description
Technical field
This utility model is for using the microporous phase changing device that microporous medium is converted to liquid phase gas phase.Belong to the disinfection technology category, especially refer to be applied in the low-temperature plasma sterilizing installation, realize by liquid state-gasiform conversion being ionized the liquid sterilant that forms plasma.
Background technology
Be successfully applied to clinically from Minimally Invasive Surgery, various endoscopy are popularized in hospital day by day, and the thorough sterilization of operation that brings thus and examination apparatus is the problem that patient, clinical medical and nursing personnel and hospital administrators are very paid close attention to always.
Many armarium are to be constituted or had complicated lens device (as firm or softish endoscope) by plastics or rubber bodies.High pressure steam sterilization may damage this armarium or shortened dramatically their service life.For solving the damage problem of high pressure steam sterilization to armarium, also the someone adopts the mode of glutaraldehyde soak at room temperature to come armarium is sterilized, but soak time is longer relatively, and normal step institute must also want three and a half hours the time.In addition also the someone adopts the mode of epoxyethane fumigation to come armarium is sterilized, but because oxirane is a kind of unsettled toxic gas, also can damage operator's health, and the processing of oxirane also is a problem after the sterilization treatment.
In order to solve the deficiency on the armarium sterilizing methods, U.S. Johnson ﹠ Johnson Medical, Inc is developing in the period of 1996 utilization hydrogen peroxide steam disinfectant method (Chinese invention patent number 97113795.1) it is to desire the step that the disinfectant device is handled with the hydrogenperoxide steam generator that dilutes earlier before being exposed to vacuum or following isoionic vacuum, promptly when causing described vaporizer by vacuum, allow hydrogen peroxide being enough to realize that disinfectant keeps in the time and desire disinfectant device contacts, to reach the effect of cold sterilization.But this mode fails to propose the simple and direct mode of source of the gas input and liquid gas shift when implementing, this situation promptly directly has influence on the efficient of sterilization operation, if its gasification efficiency can be improved, promptly can shorten the time of disinfecting process, and improve the efficient of sterilization operation.
Korea S manufacturer has designed gaseous hydrogen peroxide has been sent into the device that in the plasma sterilization device that medical object subject to sterilization is housed this medical object is carried out sterilization treatment in order to improve the gasification efficiency of hydrogen peroxide.As application number is in the 00819366.5 Chinese invention patent application case, promptly liquid hydroperoxide is gasificated into gas with injection heater, by mass flow controller gaseous hydrogen peroxide is adjusted to the pressure that needs and injects under this pressure then and make it produce plasma in the plasma sterilizer, wherein medical object is carried out sterilization treatment.Yet the related device of this kind method is obviously more, and mass flow controller is comparatively loaded down with trivial details, increases unnecessary cost.
Also there is manufacturer to develop the identical decontaminating apparatus of similar technology that utilization U.S. Johnson ﹠ Johnson Medical, Inc develops in addition at home, device as shown in the patent No. 02260590.8 Chinese utility model patent case fails to propose the simple and direct mode of source of the gas input and liquid gas shift.
