Example (b):
referring to fig. 1-8, a medical disinfection cabinet for cleaning medical instruments comprises a cabinet body 1, a cabinet door 2 and a disinfection chamber 3 for placing medical instruments, wherein the disinfection chamber 3 is arranged inside the cabinet body 1, the cabinet door 2 seals the disinfection chamber 3, and a comprehensive treatment assembly for cleaning and disinfecting the medical instruments is arranged inside the cabinet body 1;
the comprehensive treatment assembly comprises a water feeding assembly capable of adjusting the temperature of water delivery, a bearing frame 4 fixedly arranged in the middle of the inside of the cabinet body 1, a movable plate 5 movably arranged above the bearing frame 4, a pressure valve 6 fixedly arranged at the discharge end of the bottom of an inner cavity of the disinfection chamber 3, a heating block 15 fixedly arranged at the top of the inner cavity of the disinfection chamber 3, a second electromagnetic valve 21 fixedly arranged above one side of the cabinet body 1 and a negative pressure assembly for forming a negative pressure environment inside the disinfection chamber 3, wherein liquid drops are injected into the upper part of the inner cavity of the disinfection chamber 3 by the water feeding assembly, the size of the injected liquid drops is adjustable each time, the injected liquid drops are further heated by the heating block 15, a cleaning groove 7 for placing medical instruments is arranged in the middle of the upper part of the bearing frame 4, a plurality of first through holes 8 penetrating through the bearing frame 4 are arranged inside the bottom wall of the cleaning groove 7, a plurality of second through holes 9 penetrating through the upper part and the lower part are arranged in the middle part of the movable plate 5, the size of first through-hole 8 is greater than the size of second through-hole 9, and the feed end and the 6 discharge end of pressure valve intercommunication of negative pressure subassembly, the velocity of flow when negative pressure subassembly improves gas and liquid and passes through second through-hole 9 and first through-hole 8, and makes liquid take place to sputter simultaneously. The flow through the pressure valve 6 is conveniently regulated by regulating the suction of the negative pressure assembly.
The air inlet end of the second electromagnetic valve 21 is provided with a filter for filtering impurities, and when cleaning, the medical apparatus is placed in the bearing frame 4, the movable plate 5 is covered, and the cabinet door 2 is closed. Send the water subassembly from 3 inner chambers top injection temperature's of disinfection room small particle size liquid drops, negative pressure subassembly is bled to 3 inner chambers of disinfection room simultaneously, pressure valve 6 and second solenoid valve 21 are opened, form high-speed air current in first through-hole 8 and second through-hole 9, high temperature small particle size liquid drops to fly leaf 5 surfaces to pass at a high speed when passing through first through-hole 8 and second through-hole 9, sputter medical instrument surface, constantly wash medical instrument surface adhesion impurity. The water feeding assembly sprays small-particle-size liquid drops, so that water is uniformly dispersed on the surface of the movable plate 5, throttling is facilitated, and the effect of saving water is achieved; the high-speed small-particle-size liquid drops impact and clean the medical instrument, so that the surface of the medical instrument is cleaned conveniently, and impurities at included angles and the like are washed out. Simultaneously because medical instrument presses in the inside of bearing frame 4, the small-particle diameter liquid drop constantly flows into medical instrument and bears the frame and form the small size rivers between 4 after attached to medical instrument surface, and inside high-speed air current sucked rivers high-speed second through-hole 9, high-speed rivers and gas washed the medical instrument bottom in this process, with medical instrument bottom sanitization for the washing to medical instrument is cleaner. This design is washed through high temperature for soluble impurity is dissolved in the thermal current, and reduces the adnexed to other impurity, is convenient for clear up the surperficial impurity of apparatus cleaner, has further promoted the device and has washd edulcoration ability.
And, the generated impurities are discharged from the pressure valve 6 under the water current washing. After the cleaning is finished, the heating block 15 heats and dries the inner cavity of the disinfection chamber 3 to form hot air flow, so that the inside of the disinfection chamber 3 is dried conveniently, and medical instruments are dried conveniently, and impurities are not easy to adhere to the surface of the medical instruments when the medical instruments are taken out, and the medical instruments are not easy to be polluted. Wherein the outside air enters the upper part of the inside of the disinfection chamber 3 after the second electromagnetic valve 21 is opened, thereby being convenient for ensuring the air pressure balance inside the disinfection chamber 3 and ensuring the cleaning and drying effects.
After the cleaning, the medical instrument is taken out and packaged by using steam sterilization paper (heat-resistant, moisture-proof and steam-permeable) with good air permeability, and then is put into the sterilizing chamber 3 for sterilization, and at the moment, the packaged medical instrument is put on the surface of the movable plate 5 and covers the air inlet end of the second through hole 9. Close cabinet door 2, open earlier and send the water subassembly, send the water subassembly constantly to send into the little fog that the temperature is higher, the particle diameter is littleer to disinfection room 3 inside, and heating block 15 heats little fog, is convenient for form high temperature steam, forms high temperature high pressure environment in disinfection room 3. Then the negative pressure component is opened, the negative pressure component sucks the gas in the disinfection chamber 3 at a lower speed, the flow of the high-pressure steam input by the water delivery component and the flow sucked by the negative pressure component are the same, air pressure balance is formed in the disinfection chamber 3, at the moment, the high-pressure steam above the inner part of the disinfection chamber 3 sequentially passes through the paper for steam sterilization and the second through hole 9 to enter the lower part of the inner part of the disinfection chamber 3, and finally the high-pressure steam is discharged. This design has accelerated the air current exchange of high temperature steam inside and outside the paper for steam sterilization paper inside remains high temperature high pressure state all the time, is convenient for make high pressure steam get into steam sterilization paper inside and disinfect to medical instrument, has improved the efficiency of disinfecting. The device can not avoid heat transfer to cause heat loss, so that the steam temperature at the position far away from the heat source is lower, in the process, the movable plate 5 and the bearing frame 4 have certain temperature insulation effect on the upper part and the lower part of the inner cavity of the disinfection chamber 3, and the upper part of the inner cavity of the disinfection chamber 3 is always in a good high-temperature state. 3 inner chamber high temperature steam of disinfection room is in from the top down mobile state always, is convenient for constantly lead medical instrument with the high temperature steam of 3 tops in disinfection room and heats to discharge away the colder gas of 3 inside belows in disinfection room from negative pressure component, it is better to the gas exhaust effect that the temperature is lower, and then make medical instrument surface be heated evenly, it is more comprehensive to make disinfect, it has the gas that the temperature is lower to lead to the incomplete problem of disinfecting to medical instrument to have solved 3 inside existence temperatures in disinfection room.
