Description

Technical Field

[0002] In the medical field, operating room air cleanliness is a key element in ensuring surgical safety. Air purification and circulation equipment, a key component in maintaining this environment, has a direct impact on surgical outcomes and patient recovery. During surgery, airborne pollutants such as bacteria, viruses, surgical smoke, anesthetic waste gases, and dust particles can cause infection through surgical wounds, increasing the risk of postoperative complications. Therefore, air purification and circulation equipment with efficient purification capabilities and stable circulation functions has become an indispensable medical auxiliary device in the operating room.

[0003] During the long-term operation of traditional operating room air purification circulation equipment, when filtering particulate matter in the air for a long time, a large amount of particulate matter is easily attached to the front surface of the pre-filter. In order not to affect the normal interception function of the pre-filter on particulate matter, the front surface of the pre-filter needs to be cleaned frequently. However, when cleaning, it is necessary to use tools to remove the front cover before cleaning can be carried out. The operation is not only time-consuming and labor-intensive, but also affects normal use due to occupying the operating room for too long. In addition, during the cleaning process, the particulate matter falling from the pre-filter will also spread into the air of the operating room, causing secondary pollution and reducing the air cleanliness of the operating room.

[0015] The present invention provides an air purification circulation device for an operating room with a sterilization structure, which has the following beneficial effects:

[0016] The present invention adopts the design of the automatic cleaning mechanism. When cleaning the pre-filter, it can automatically move up and down with the bristles, thereby sweeping away a large amount of particulate matter attached to the front surface of the pre-filter. During the cleaning process, the cleaning work can be carried out without removing the front cover, which not only saves time and effort, but also effectively reduces the time occupied in the operating room, greatly improving the practicality and ease of operation of the air purification circulation equipment in the operating room environment. In addition, the structure is simple, and particulate matter is not easily affected by it, thereby improving the reliability of the automatic cleaning mechanism during operation.

[0017] The present invention adopts the design of a circulating dust removal mechanism. During the process of cleaning the pre-filter, the airflow on the upper end of the special-shaped guide plate drives the pneumatic impeller to rotate, and the pneumatic impeller drives the transmission shaft and the suction impeller to rotate. Under the action of negative pressure, the particles swept away by the bristles are transported to the sleeve and the filter bag, and then the particles are intercepted by the filter bag, avoiding the phenomenon of particles being scattered into the air of the operating room during the cleaning process, preventing secondary pollution, and thus effectively improving the air cleanliness of the operating room.

[0018] The present invention adopts the design of the anti-blocking component. Before cleaning the pre-filter, the four electromagnets are energized to generate magnetism, and the metal plate is magnetically attracted forward under the action of the magnetism, so that the pin is inserted into the mesh holes on the pre-filter, thereby blocking the mesh holes on the pre-filter, preventing the bristles from sweeping particles into the mesh holes during the cleaning process, and when the pin is inserted forward into the mesh holes, it can also push the particles in the mesh holes forward, further improving the cleaning effect of the pre-filter and ensuring the normal interception function of the pre-filter for particles.

[0019] The present invention adopts the design of the quick limit assembly, and when replacing the sterilization filter element, it is only necessary to manually rotate the T-shaped pinching plate clockwise, so that the two plug rods can be moved in opposite directions at the same time, so that the two plug rods are respectively pulled out from the sockets on the two plug-in plates, and then the sealing plate is rotated open, and finally the sterilization filter element is replaced. During the replacement process, there is no need to use tools for tedious disassembly work, thereby effectively improving the convenience of replacing the sterilization filter element.

[0020] The present invention coats the front and rear surfaces of the sterilization filter element with an antibacterial coating, and the antibacterial coating is a silver ion antibacterial layer. The silver ion antibacterial layer can combine with bacterial cell membranes, cell walls, and internal proteins, enzymes and other biological macromolecules to destroy their physiological functions and kill common bacteria such as Escherichia coli and Staphylococcus aureus, thereby greatly improving the hygienic safety of the air purification circulation equipment during use and providing more reliable air purification protection for the operating room environment.

[0062] The working principle of the present invention is as follows: when in use, the drive motor 106 is started through the control panel 201, and the exhaust impeller 107 is rotated.

[0063] When the front surface of the pre-filter 2010 needs to be cleaned, the staff only needs to start the winding motor 306 through the control panel 201.

Then, the sliding block 301 moves downward under the action of its own gravity and the gravity of the counterweight block 308. When the sliding block 301 moves downward to the limit position, The counterweight block 308 presses the button on the forward switch 309, and at this time controls the winding motor 306 to rotate the reel 307 clockwise, and rewinds the upper end of the pull rope 304 again, and the lower end of the pull rope 304 moves upward with the sliding block 301, and the cycle operation is repeated, so that the sliding block 301 can move back and forth. The sliding block 301 that moves back and forth moves the brush 303 up and down, thereby sweeping away a large amount of particulate matter attached to the front surface of the pre-filter 2010, and during the cleaning process, the cleaning work can be carried out without removing the front cover 6, which not only saves time and effort, but also effectively reduces the time occupied by the operating room, thereby greatly improving the practicality of the air purification circulation equipment.

[0064] During the cleaning process of the pre-filter 2010, there is no need to stop the drive motor 106. The airflow passing through the upper end of the special-shaped guide plate 104 will drive the pneumatic impeller 109 to rotate, and the pneumatic impeller 109 will drive the transmission shaft 108 and the suction impeller 4010 to rotate, thereby sucking the air inside the suction pipe 402, the separation box 403, the suction hose 405 and the suction cover 407 into the suction housing 401. At this time, under the action of negative pressure, the particles swept away by the brush 303 are sucked into the suction cover 407 through the suction through hole 3011, and then the particles are transported to the sleeve 4013 and the filter bag 4011 through the suction hose 405. The particles are then intercepted by the filter bag 4011, thereby avoiding the phenomenon of particles being scattered into the air of the operating room during the cleaning process and preventing secondary pollution, thereby effectively improving the cleanliness of the air in the operating room. The separated air is discharged to the inside of the front cover 6 through the return air duct 406 and the return air outlet 602; when cleaning the particles inside the filter bag 4011 at a later stage, it is only necessary to unscrew the hand-tightening bolt 408 from the nut 409, open the box cover 404, and then untie the binding rope 4012, and remove the filter bag 4011 from the outside of the sleeve 4013 for cleaning, which effectively improves the convenience in cleaning the collected particles.

[0065] Before cleaning the pre-filter 2010, the control board 201 can be used to control the current to enter the four electromagnets 705, so that the electromagnets 705 are energized and generate magnetism. Under the action of magnetism, the metal plate 701 is magnetically attracted forward, so that the pin 704 is inserted into the mesh on the pre-filter 2010, and the mesh on the pre-filter 2010 is blocked to prevent the bristles 303 from sweeping particles into the mesh during the cleaning process. When the pin 704 is inserted forward into the mesh, the particles in the mesh can be pushed forward, further improving the cleaning effect of the pre-filter 2010 and avoiding affecting the normal interception effect of the pre-filter 2010 on particles.
