[0002] Medical device disinfection is a crucial part of medical work. Its purpose is to eliminate or reduce pathogenic microorganisms on the equipment and prevent cross infection. Currently, the common methods for medical device disinfection include dry heat disinfection, wet heat disinfection, chemical disinfection, and ultraviolet disinfection.

[0003] Among them, the most commonly used moist heat disinfection is steam disinfection, which uses the moist heat conditions and good penetrating power of high-temperature steam to coagulate and denature bacterial proteins, thereby killing microorganisms.

[0030] A steam concentration box 5 is bolted to the top of the box body 1, a steam inlet pipe 6 is welded to the steam concentration box 5, the steam inlet pipe 6 is connected to the inside of the steam concentration box 5, the end of the steam inlet pipe 6 away from the steam concentration box 5 passes through the box body 1 and extends to the rear side of the box body 1, a plurality of upper sleeves 8 are installed at equal intervals on the bottom of the steam concentration box 5, the upper sleeves 8 are fixed to the steam concentration box 5 by bolts, the top surface of the upper sleeve 8 and the bottom surface of the steam concentration box 5 at the corresponding position are opened, and the upper sleeve 8 is connected to the inside of the steam concentration box 5 through the opening;

[0031] The lower sleeve 7 is welded and installed on the bottom surface of the upper sleeve 8, and the bottom surface of the lower sleeve 7 is open. The net tray 3 is located directly below the lower sleeve 7. A plurality of connecting pipes 9 are welded and installed on the outer peripheral wall of the upper sleeve 8. The bottom end of the connecting pipe 9 away from the upper sleeve 8 is welded and fixed to the outer peripheral wall of the lower sleeve 7 near the top. The upper sleeve 8 and the lower sleeve 7 are internally connected through the connecting pipe 9. An outer sleeve ring 10 is provided in the lower sleeve 7 below the bottom end of the connecting pipe 9. The outer peripheral wall of the outer sleeve ring 10 is close to the inner peripheral wall of the lower sleeve 7. Limiting rings 13 that abut against the upper and lower surfaces of the outer sleeve ring 10 are welded and installed on the inner peripheral wall of the lower sleeve 7 on the upper and lower sides of the outer sleeve ring 10.

[0032] An inner circular plate 11 is provided in the lower sleeve 7 at the center position of the outer ring 10, and the inner circumferential wall of the outer ring 10 and the outer circumferential wall of the inner circular plate 11 are integrally formed and fixed by multiple fan blades 12. A partition 14 is welded and installed at the bottom position in the lower sleeve 7, and multiple uniform air outlet holes 18 are opened on the partition 14. A connecting column 15 is welded and installed on the bottom surface of the inner circular plate 11, and the bottom surface of the connecting column 15 abuts against the top surface of the partition 14. A plurality of laterally extending fixing rods 17 are welded and installed on the connecting column 15, and a plurality of ball blocks 16 corresponding to the air outlet holes 18 are welded and installed on the fixing rods 17. The ball blocks 16 are close to the top of the air outlet holes 18 but do not abut each other. The air outlet holes 18 are centered on the center of the partition 14 and are arranged in three concentric rings. The ball blocks 16 are arranged at the position of the air outlet holes 18 in each ring, and the number of air outlet holes 18 is not less than two in the spacing between adjacent ball blocks 16 in each ring.

[0033] Before use, the steam inlet pipe 6 is connected to the existing steam generator to supply steam centrally. When in use, the box door 2 is opened, and the medical instruments to be sterilized are placed on the two mesh trays 3, among which the medical instruments with more dead corners for self-cleaning or sterilization are placed on the upper mesh tray 3. The medical instruments on the upper mesh tray 3 shall not be stacked, while the medical instruments on the lower mesh tray 3 can be stacked. After placement, the box door 2 is closed and opened from the steam generator position for steam supply. The steam first enters the steam concentration box 5 through the steam inlet pipe 6, then enters the upper sleeve 8, and enters the lower sleeve 7 through the connecting pipe 9. In the lower sleeve 7, since only the fan blade 12 position is connected, the steam can only pass through this position. At the same time, due to the structural characteristics of the fan blade 12, when the steam passes through, it will push the fan blade 12 to rotate, thereby driving the connecting column 15 to rotate. The connecting column 15 The rotation drives the ball block 16 to rotate with the connecting column 15 as the axis. When the steam passes over the fan blade 12 and gushes out through the air outlet 18 of the partition 14, the air outlet 18 that the ball block 16 is not close to is completely open, and the steam flow rate is large and stable. When the ball block 16 rotates and approaches the air outlet 18, due to the obstruction of the ball block 16, the steam flow rate of the air outlet 18 is reduced at this time. The continuous rotation of the ball block 16 makes all the air outlets 18 present a pulse feature with orderly fluctuations in steam volume. The steam pulse outflow can form an impact effect on the surface of the medical device on the top mesh tray 3, which can be used for cleaning. The impact can also increase the contact surface and contact force with the device, and it also has a good disinfection effect on some dead corners or component connection gaps. At the same time, the pulse can quickly exchange heat with the surface of the device and accelerate the sterilization speed.

[0034] In this embodiment, the bottom end of the connecting tube 9 at the position of the lower sleeve 7 is arranged horizontally and downwardly, and the surface horizontal angle between the connecting tube 9 and the axis of the lower sleeve 7 is 10°-12°, and the vertical angle is 80°-75°.

[0035] The inclined connection pipe 9 allows the steam entering the lower sleeve 7 to first contact the inner wall of the lower sleeve 7, forming a downward rotation feature around the inner wall of the lower sleeve 7. The downward rotation feature can increase the driving force on the fan blades 12 when contacting the fan blades 12 to ensure that the fan blades 12 rotate reliably.

[0036] In this embodiment, a pump box 20 is welded and installed on the rear side of the box body 1. A vacuum pump 19 is installed in the pump box 20. The vacuum pump 19 is connected to the inside of the box body 1 through a pipeline.

[0037] After placing the medical device and closing the box door 2, the vacuum pump 19 can be turned on to evacuate the inside of the box 1 to form a negative pressure inside, and then steam can be introduced. At this time, the steam can penetrate the cell membrane more quickly to sterilize and disinfect.

[0038] In this embodiment, a heat insulating pad 21 is installed on the front of the box body 1 above the box door 2, an industrial control integrated machine 22 is installed on the front of the heat insulating pad 21, and the vacuum pump 19 is electrically connected to the industrial control integrated machine 22.

[0039] During operation, it can be directly controlled from the industrial control all-in-one machine 22. The thermal insulation pad 21 can reduce the conduction of heat in the box 1 to the industrial control all-in-one machine 22 to maintain the continuous, reliable and stable operation of the industrial control all-in-one machine 22. Temperature sensors, pressure sensors and other instruments can also be installed in the box 1 as needed, and the industrial control all-in-one machine 22 can display the disinfection status inside the box 1. This is all foreseeable.
