[0002] In the field of urological surgery nursing, the disinfection of medical devices is of vital importance. The current disinfection technologies mainly include ultraviolet disinfection, high-temperature steam disinfection, alcohol disinfection, etc. Among them, steam disinfection is mainly carried out through diffuse steam disinfection, using high-temperature and high-pressure steam to kill bacteria, viruses and other microorganisms, and is highly efficient, broad-spectrum and environmentally friendly.

[0021] The air-drying component 27 includes an air pump 15 fixedly installed on the outer wall of the bottom of the water storage barrel 8, a transmission pipe 16 fixedly installed on the side wall of the water storage barrel 8, a curved pipe 17 vertically slidably installed in the transmission pipe 16, and a blow head 18 fixedly installed on the free end of the curved pipe 17, wherein the blow head 18 corresponds to the placement cage 6, and the blow head 18 is fixedly connected to the bottom wall of the top cover 4.

[0022] The closed injection assembly 7 includes a pressure relief valve 11 fixedly arranged in the top plate 3, an air cylinder 28 fixedly arranged on the lower wall of the top plate 3, a piston 13 movably arranged in the air cylinder 28, a pressure relief valve 12 fixedly arranged on the upper wall of the piston 13, and a connecting column 14 fixedly arranged at the lower end of the piston 13, the lower end of the connecting column 14 is fixedly connected to the upper wall of the top cover 4, the pressure relief valve 11 is connected to the inside of the air cylinder 28, the piston 13 and the connecting column 14 are provided with through holes, the through holes penetrate the connecting column 14 and the top cover 4, and the pressure relief valve 2 12 is connected to the through holes.

[0023] A sealing gasket 25 is fixedly disposed on the lower wall of the top cover 4 , and the sealing gasket 25 corresponds to the outer edge of the top of the sterilizing barrel 5 . When the sealing gasket 25 contacts the upper edge of the sterilizing barrel 5 , the air jet hole 24 corresponds to the placement cage 6 .

[0024] A vibration sensor 9 is fixedly provided on the upper wall of the top cover 4, and the model of the vibration sensor 9 is Honeywell IN-Z61. A central processing unit 10 is fixedly provided on the upper wall of the bottom plate 1, and the model of the central processing unit 10 is: PIC16F84A. The central processing unit 10 is electrically controlled and connected to the vibration sensor 9, and the central processing unit 10 is electrically controlled and connected to the air pump 15 and the electric heating tube 20.

[0025] The gas output of the jet hole 24 is smaller than the amount of steam generated inside the water storage barrel 8 , and the threshold of the pressure relief valve 1 11 is smaller than the threshold of the pressure relief valve 2 12 .

[0026] During specific use, in the initial state, due to the tension of the reset tension spring 21, the top cover 4 itself is in a lifted state, and the placement cage 6 is located above the disinfection barrel 5. First, the cage door is opened, and the urological surgical nursing instruments to be disinfected are placed in the placement cage 6, and then the cage door of the placement cage 6 is closed, and then the electric heating tube 20 is turned on. The electric heating tube 20 heats the water in the water storage barrel 8. At this time, steam will be sprayed from the delivery pipe 23 and the jet hole 24 into the disinfection barrel 5 to perform steam jet disinfection on the nursing instruments. Since the air output of the jet hole 24 is less than the air output of the steam, the air pressure in the water storage barrel 8 will gradually increase. When the air pressure in the water storage barrel 8 is greater than the threshold value of the pressure relief valve 11, the steam in the water storage barrel 8 will enter the air cylinder 28 from the air pipe 19 and the pressure relief valve 11. At this time, the air in the air cylinder 28 The steam will push the piston 13, the connecting column 14 and the top cover 4 to move downward. When the top cover 4 contacts the sterilizing barrel 5, the piston 13 cannot move downward any further. At this time, the air pressure in the air cylinder 28 gradually increases. When the air pressure in the air cylinder 28 is greater than the threshold of the pressure relief valve 12, the steam will pass through the piston 13, the connecting column 14 and the top cover 4 through the through hole 29, and finally enter the sterilizing barrel 5, and spray the steam again to the nursing equipment in the cage 6. At this time, the air pressure in the sterilizing barrel 5 gradually increases. When the air pressure in the sterilizing barrel 5 increases to a certain extent, the top cover 4 will be pushed up. At this time, the vibration sensor 9 receives the vibration signal of the top cover 4 and transmits the vibration signal to the central processing unit 10. The central processing unit 10 issues an opening command to the air pump 15 and a closing command to the electric heating tube 20 at the same time. Subsequently, the return spring 21 drives the top cover 4 to return slowly. Due to the tension of the return spring 21, the gas in the cylinder 28 is squeezed by the piston 13. At this time, the gas in the cylinder 28 enters the air pipe 19, the water storage barrel 8 and the delivery pipe 23 from the pressure relief valve 11 in sequence, and is finally slowly discharged from the air jet hole 24. When the top cover 4 is reset to the initial position, the placement cage 6 corresponds to the horizontal position of the blower head 18, and the air pump 15 is in the on state at this time. The air pump 15 transmits the external air into the curved pipe 17, and then blows it from the blower head 18 to the placement cage 6, so as to air-dry the nursing equipment that has been disinfected inside the placement cage 6. In this process, since the gas passes through the water storage barrel 8 during the circulation process, the residual heat of the hot water inside the water storage barrel 8 is used to heat the airflow, which effectively utilizes the thermal energy. At the same time, the heating of the airflow can also improve the air-drying efficiency.

[0027] The amount of steam generated can be controlled by changing the power of the electric heating tube 20, thereby controlling the time of steam sterilization. The greater the power of the electric heating tube 20, the greater the amount of steam generated. More steam enters the sterilization barrel 5 and the shorter the sterilization time. The same is true vice versa.

[0028] In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creatively designing without departing from the purpose of the invention, they should all fall within the scope of protection of the invention.
