Preferably, the ultraviolet disinfection lamp 26 is provided in plurality and arranged along the inner wall of the cleaning container 1.
Preferably, the bottom of the cleaning container 1 is tapered, and the outflow channel 10 and the filter screen 11 are coaxial with the taper, so that the fluid in the cleaning container 1 can be ensured to completely flow through the filter screen 11 and enter the outflow channel 10, and no residue is left in the cleaning container 1.
Preferably, the upper end of the vertical pipe 6 is provided with a water injection funnel 27 to facilitate water injection operation.
Preferably, the upper end of the vertical pipe 6 is provided with a water filling plug 28, so that on one hand, external bacteria, dust and the like can be prevented from entering the water storage container 3, and on the other hand, when the float 7 normally floats and the lower end of the vertical pipe 6 is still higher than the liquid level in the water storage container 3, the water filling plug 28 can ensure the sealing of the water storage container 3, so that the subsequent air suction operation can be smoothly carried out.
When the invention is used, the water storage container 3 is filled with water or cleaning fluid, the floater 7 floats upwards to enable the sealing pressing sheet 8 to be far away from the vent hole 9, the vent hole 9 is in an open state, and meanwhile, the liquid in the water storage container 3 enters the suction channel 4 and is consistent with the liquid level in the water storage container 3; the gland nut 23 is unscrewed and the vessel lid 2 is removed, the tool to be cleaned or sterilized is fixed to the vessel lid 2 using the holding means 15, and then the vessel lid 2 is screwed to the cleaning vessel 1 and sealed again.
Starting the water-air dual-purpose pump 13, and because the pumping end of the water-air dual-purpose pump 13 is communicated with the interior of the cleaning container 1, negative pressure is generated in the cleaning container 1, so that the liquid in the water storage container 3 is sequentially sucked into the cleaning container 1 through the suction channel 4, the interlayer 20 and the nozzle 5, and jet flow is generated through the nozzle 5 to flush a tool fixed on the container cover 2; because the nozzles 5 are uniformly distributed along the wall of the cleaning container 1, water flow scouring tools can be ensured to be arranged in all directions, and no dead angle cleaning is realized.
The flushed water is collected at the bottom of the cleaning container 1 and flows to the outflow channel 10, the tissue, medicine and the like flushed by the tool are filtered by the filter screen 11, and the filtered liquid is sucked by the water-air pump 13 and discharged into the waste water container 18 through the pump-out pipe 17.
Along with the liquid in the water storage container 3 reduces gradually, the floater 7 drops along with the liquid level continuously to enable the sealing pressing sheet 8 to be close to the upper end of the vent hole 9, when the liquid level is lower than the lower end of the suction channel 4, the sealing pressing sheet 8 seals the vent hole 9 to enable the water storage container 3 to be completely sealed, at the moment, the liquid level in the water storage container 3 is lower than the lower end of the suction channel 4, so that the liquid does not enter the cleaning container 1 any more, and the cleaning operation is finished.
However, since the pump 13 is still operated, the liquid and gas remaining in the cleaning vessel 1 and the air in the water reservoir 3 are continuously pumped out to continuously reduce the internal pressure of the cleaning vessel 1 and the water reservoir 3 to generate negative pressure, and at this time, the pump 13 can be manually turned off and the ultraviolet sterilizing lamp 26 can be turned on, or the pump 13 and the ultraviolet sterilizing lamp 26 can be automatically controlled by an automatic control circuit according to the running time of the equipment, the internal pressure of the cleaning vessel 1 or the liquid level in the water reservoir 3.
Due to the one-way stopping function of the one-way valve 12, when the water-air pump 13 stops operating, the external air or liquid cannot flow back into the cleaning container 1 through the outflow passage 10, so that the internal pressure of the cleaning container 1 is kept stable.
In the washing process, tissues attached to the tool are washed clean, so that bacteria, viruses, microorganisms and the like lose nutrients to reduce the growth and propagation speed, and under the condition of washing by using a cleaning solution, the effects of disinfection and sterilization can be directly achieved, so that the number of surface flora of the washed tool is obviously reduced; under the action of negative pressure, bacteria, viruses, microorganisms and the like attached to tools inside the cleaning container 1 are further inhibited from growing and propagating due to changes of pressure inside and outside cells and oxygen environment, and the negative pressure action exists in each corner inside the cleaning container 1, so that the bacteriostatic effect can be ensured to be more ideal; meanwhile, a plurality of ultraviolet disinfection lamps 26 are uniformly distributed along the inner wall of the cleaning container 1, so that ultraviolet rays can be radiated from various angles at the same time, the dead angle of radiation is eliminated, the killing speed is improved, complete sterilization is realized, and the sterilization and disinfection effects of the invention are obviously improved.
After the cleaning and killing are finished, the container cover 2 cannot be directly taken down due to the action of negative pressure, so that the air inlet valve 21 needs to be opened, and external air enters the cleaning container 1 through the air inlet valve 21, so that the internal pressure and the external pressure of the cleaning container 1 gradually tend to be balanced; after the air-intake operation is completed, the container lid 2 is opened and the tool is taken out.
After the operation is finished or before the next use, the filter screen 11 should be taken out for cleaning or replacement, and the waste water in the waste water container 18 is discharged through the drain outlet 19.
The negative pressure bacteriostatic cleaning device is compact in structure and convenient and fast to operate, flushing cleaning of medical tools and negative pressure bacteriostatic cleaning are realized by utilizing the negative pressure generated by the water-gas dual-purpose pump, manual switching is not needed for the two operations, the negative pressure bacteriostatic operation is automatically started after the cleaning is finished, and the whole process is more convenient and humanized.
The invention does not depend on large-scale auxiliary equipment, so the volume is smaller, and the invention is suitable for carrying and using in a consulting room, an operating room or outdoor rescue; under the combined action of negative pressure bacteriostasis and ultraviolet killing, the invention has the advantages of higher killing speed, shorter time consumption, more thorough killing, improved turnover rate of using instruments, suitability for most medical scenes and capability of effectively ensuring real-time and quick cleaning and killing of medical tools.
Based on the prior art, the medical staff can be better served by arranging a simple automatic control system, and the work burden of the medical staff is greatly reduced.
