The working process comprises the following steps: the invention is divided into three stages of disinfection soaking, flushing and drying.
Soaking: firstly, workers sort the polluted instruments into different flushing cylinders 221, cover the net cover 230, an external motor drives the soaking tank 110 to slowly ascend along the sliding rail column 520 through a connecting shaft, an electrolytic water device is arranged in the soaking tank 110 to electrolyze the injected water to generate disinfectant capable of killing bacteria and viruses, the soaking tank 110 ascends to a preset position to stop, and the disinfectant generated by the electrolytic water submerges the surgical instruments. After a set time, the soaking bath 110 descends along the rail 520, and the soaking solution contains inactivated viruses and bacteria, but the PH is not suitable for discharge.
And (3) flushing: then, the motor 210 slowly rotates the plurality of washing drums 221 through the belt. The sterilizing water flows out of the water supply apparatus 400 through the water supply pipe 410 into the flushing assembly 220 through the plurality of first water inlets 2221. When one of the nozzle pendulum 2214 in the flushing cylinder 221 is communicated with the water diversion groove 2222, the sterilizing water enters the flushing cylinder 221 through the nozzle pendulum 2214 to flush the instrument, and at this time, the other nozzle pendulum 2214 can assist the turning of the instrument in the flushing cylinder 221 in the rotating process.
The protrusion 2232 is inserted into the spiral chute, and when the protrusion 2232 is in the first spiral groove 600, the washing cylinder 221 is rotated, and the piston cover 223 is moved along the axis of the washing cylinder 221 and gradually away from the washing cylinder 221, and the space of the piston chamber 224 is gradually increased. At this time, a part of the sterilizing water flowing into the flushing unit 220 flows into the flushing cylinder 221 for flushing the instrument, and the other part flows into the piston chamber 224 to be stored, at this time, the water flow ejected from the nozzle pendulum 2214 is relatively small, the low-pressure water flow in the first half period is shown in fig. 14, H3 is the initial position of the low-pressure water flow, H4 is the final position of the low-pressure water flow, and the water flow is flushed from the left side to the right side as the nozzle pendulum 2214 rotates clockwise.
When the boss 2232 is in the second spiral groove 601 after the washing drum 221 is rotated by half a cycle, the washing drum 221 is rotated, the piston cover 223 is moved along the axis of the washing drum 221 and gradually approaches the washing drum 221, the space of the piston chamber 224 is gradually reduced, and the sterilizing water in the piston chamber 224 is discharged. At this time, a part of the sterilizing water flowing into the washing cylinder 221 flows from the outside, and the other part is extruded from the inside of the piston chamber 224, and at this time, the water flow ejected from the nozzle pendulum 2214 is relatively large, and the high-pressure water flow in the second half period is shown in fig. 13, where H1 is the initial position of the high-pressure water flow, and H2 is the final position of the high-pressure water flow. As the spray head pendulum 2214 rotates clockwise, the water stream is rushed from the right side to the left side. The flow of water thus continues to scan the rinsing apparatus back and forth, with the flow of rinsing water exiting the through holes and being collected by the infusion tank 110.
And (3) a drying stage: after the washing is completed, the sterilizing liquid in the soaking tank 110 is decomposed under the irradiation of the fluorescent lamp 310 and reduced to a safely discharged waste liquid with a pH of approximately 7, and simultaneously the exhaust fan 320 draws air outwards to take away water vapor and accelerate drying. The invention has been completed so far: disinfecting, soaking, washing, drying, sterilizing and disinfecting, and purifying waste liquid.
H1, high-pressure water flow initial position; h2, high pressure water flow final position; h3, low-pressure water flow initial position; h4, low pressure water flow end point.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
