The specific embodiment
Below in conjunction with drawings and Examples this utility model is described in further detail.
Shown in Fig. 1 ~ 10, a kind of hydrogen peroxide low temperature plasma sterilizer, comprise body 1, cylindrical shell 2, inner core 3, vacuum orifice 4, control system 5, power supply 6, hydrogen peroxide inlet 7, programmable controller 8, air inlet 9 and air vent 11, cylindrical shell 2 is installed on the body, vacuum orifice 4, air inlet 9, air vent 11 and hydrogen peroxide inlet 7 all communicate with cylindrical shell 2 inner chambers by the pipeline that is provided with valve 13, inner core 3 is installed in the cylindrical shell 2 by rest pad 2-1, carriage 3-3 is installed in the inner core 3, inner core 3 is made up of the bag circle 3-2 at inner tube wall 3-1 and inner tube wall two ends, bag circle 3-2 is provided with groove 3-2-1, be embedded with insulated ring 3-4 in this groove 3-2-1, the two ends of inner tube wall 3-1 are inserted in this insulated ring 3-4, are evenly distributed with through hole 3-5 on the inner tube wall 3-1.

Work process of the present utility model is as follows:
Sterilization process is two circulation sterilizations, divides four-stage: stage of preparation, and the first sterilization phase, the second sterilization phase, and ventilate the phase at last.
(1) the vacuum phase is that the sterilization process phase I, (1 holder was 1Torr (torr)=lmmHg=1.33322 * lO2Pa), cavity pressure drops to 700 millitorrs through evacuation, enter the plasma stage, at this moment cavity pressure is controlled in 500 millitorrs, short circulation 10 minutes, length circulation 15 minutes, water evaporates is also extracted out outside the chamber by vacuum pump, helps to drive away article surface or inner residue moisture clean.The rear venting valve was opened in 15 minutes, entered cavity through filtered air, and when pressure reached atmospheric pressure, vacuum pump is task again, and cavity pressure is reduced to 0.4 holder.Entering second stage then, also was the first sterilization phase.
(2) first sterilization phases were divided injection stage, diffusion phase, plasma stage.At first injection needle pierces through and contains the capsule that concentration is 59% hydrogen peroxide, because intracavity has been taken out and has been fine vacuum, hydrogen peroxide is vaporization and fully diffusion rapidly, the existing lethal effect to biological tissue of this process hydrogen peroxide.Capsule is arranged in cartridge, and every box contains ten capsules, can finish five sterilization cycles, and the position of cartridge and injection are by software control and monitoring, and injection process continues 6 minutes.Enter intracavity (short circulation 2 minutes, long circulation 10 minutes) through filtered air then, make hydrogen peroxide be diffused into each corner of intracavity and by the surface of sterilized instrument.Vacuum pump drops to 0.5 holder with cavity pressure by 760 holders once more, enter the plasma stage, intracavity is written into and continues two minutes radio frequency, glow discharge takes place, hydrogen peroxide derives plasma, it can intervene the generation with destroy microorganisms, in case radio frequency stops, plasma (orifice) gas just is converted to harmless steam and oxygen.Last vacuum pump is reduced to 0.4 holder with pressure from 0.5 holder once more, enters the phase III, also is second sterilising cycle.
(3) second sterilising cycles and first sterilising cycle are identical, and the plasma stage enters the quadravalence section, ventilating stage after finishing.
(4) at ventilating stage, INO enters intracavity through filtered air, and pressure is got back to atmospheric pressure, and sterilization process finishes.Whole sterilization process continues 55 minutes, long circulation 72 minutes.
