Description

Technical Field

[0001] This utility model relates to the technical field of operating room air supply devices, and in particular to an operating room air supply device with an air handling system. Background Technology

[0002] The cleanliness level of the operating room is closely related to the efficient and safe operating room air purification system. The operating room air supply device can not only ensure the sterile environment of the operating room, but also prevent cross-infection of personnel and play an important role in ensuring the success of the operation. It is an indispensable key supporting system in the operating room. The two basic functions of the operating room air supply device are: first, to quickly replace all the polluted air in the surgical area with dust-free and sterile air to ensure that the surgical site is clean and sterile; and second, to prevent the less clean air outside the air supply airflow from seeping into the surgical area.

[0003] Currently, the filters of the operating room air supply system need to be replaced frequently by medical staff. When replacing them, medical staff have to manually touch the filters, which increases the risk of disease transmission. The replacement process is also quite troublesome. During air supply, external factors often cause the suction power of the air supply system to be weak, making it difficult to purify the air in the entire operating room. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An operating room air supply device with an air handling system includes:

[0006] A ventilation duct, wherein a baffle is fixedly installed on the lower side of the ventilation duct, and multiple ventilation openings are opened on the baffle. A support plate two is fixedly installed inside the ventilation duct, and a filter element is installed on the upper side of the support plate two.

[0007] An automatic replacement structure is installed inside the ventilation duct. The automatic replacement structure includes a motor fixedly installed on the side wall of the ventilation duct. A drive shaft is fixedly installed at the output end of the motor. Four rotating shafts are rotatably connected to the side wall of the ventilation duct. A bevel gear is fixedly sleeved on the outside of the drive shaft and one of the rotating shafts, and the two bevel gears mesh with each other. Pulleys are fixedly connected to the outside of the four rotating shafts. A belt is drivingly connected between two of the pulleys. Two support plates are fixedly connected between the two belts. A connecting plate is fixedly connected between the two support plates. A push plate is fixedly connected to the support plate. A pressing block is fixedly connected to the lower side of the support plate. A slider is slidably connected to the side wall of the ventilation duct. A pressure plate is fixedly connected to the side wall of the slider. A spring is fixedly connected between the slider and the ventilation duct.

[0008] Preferably, the ventilation duct is equipped with an air supply structure, which includes a rotating shaft rotatably connected to the side wall of the ventilation duct. Both the rotating shaft rotatably connect to the outer side of the drive shaft and a bevel gear rotatably connected to the outer side of the drive shaft, and the two bevel gears rotatably mesh with each other. Multiple rotating shafts rotatably connect to the side wall of the ventilation duct. One of the rotating shafts rotatably connects to the rotating shaft rotatably through a pulley assembly, and two adjacent rotating shafts rotatably connect to each other through a pulley assembly. A fan is fixedly fitted to the outer side of the rotating shaft rotatably.

[0009] Preferably, two lamp tubes are fixedly installed on the lower side of the ventilation duct.

[0010] Preferably, a plurality of spray pipes are fixedly installed on the side wall of the ventilation duct, and nozzles are fixedly connected to the ends of the plurality of spray pipes.

[0011] Preferably, the snap-fit ​​assembly includes a sliding sleeve slidably connected to the outside of the drive shaft, the sliding sleeve having a plurality of pins circumferentially distributed on its sidewall, and a disc fixedly connected to the outside of the drive shaft, the disc having a plurality of notches on its outer side.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model automatically replaces the filter element by using a motor-driven automatic replacement structure. The old filter element can be automatically cleaned and sterilized after replacement, eliminating the need for medical staff to manually touch the filter element for replacement. This reduces the risk of the filter element infecting medical staff. The replacement process is simple and easy to operate, and the overall process is relatively intelligent.

[0014] 2. This utility model uses a motor to drive the air supply structure to rotate, so that the air supply structure can send out the gas containing bacteria and viruses, thus avoiding secondary infection. Through the combined action of multiple fans, the suction of the air supply device will no longer be weak due to external factors, thus preventing low purification efficiency of the air in the operating room.

[0022] Reference Figures 1-6 An operating room air supply device with an air handling system, comprising:

[0023] Ventilation duct 1 has two lamp tubes 24 fixedly installed on its lower side, providing illumination for the operating room. A baffle 2 with multiple ventilation openings 3 is also fixedly installed on the lower side of ventilation duct 1. A support plate 12 is fixedly installed inside ventilation duct 1, with a filter element 4 installed on its upper side. An automatic replacement structure is installed inside ventilation duct 1, including a motor 5 fixedly installed on the side wall of ventilation duct 1. A drive shaft 6 is fixedly installed at the output end of the motor 5, and a snap-fit ​​assembly is installed on the drive shaft 6. The snap-fit ​​assembly includes a sliding sleeve slidably connected to the outside of the drive shaft 6, with multiple pins 27 distributed circumferentially on the side wall of the sliding sleeve. A disc 28 is fixedly connected to the outside of the drive shaft 6, with multiple notches 29 on the outside of the disc 28. 28 rotates in any way, with pins 27 corresponding to recesses 29. Four rotating shafts 7 are rotatably connected to the side wall of ventilation duct 1. A bevel gear 8 is fixedly sleeved on the outside of the drive shaft 6 and one of the rotating shafts 7, and the two bevel gears 8 mesh with each other. Pulleys 9 are fixedly connected to the outside of the four rotating shafts 7. A belt 10 is connected between the two pulleys 9. Two support plates 11 are fixedly connected between the two belts 10. A connecting plate 30 is fixedly connected between the two support plates 11. A push plate 13 is fixedly connected to the support plate 11. A pressing block 14 is fixedly connected to the lower side of the support plate 11. A slider 15 is slidably connected to the side wall of ventilation duct 1. A pressure plate 16 is fixedly connected to the side wall of slider 15. A spring 17 is fixedly connected between slider 15 and ventilation duct 1.

[0024] The ventilation duct 1 is equipped with an air supply structure, which includes a rotating shaft 18 rotatably connected to the side wall of the ventilation duct 1. Both the rotating shaft 18 and the drive shaft 6 are fixedly sleeved with bevel gears 19, and the two bevel gears 19 mesh with each other. Multiple rotating shafts 20 are rotatably connected to the side wall of the ventilation duct 1. One of the rotating shafts 20 is connected to the rotating shaft 18 through a pulley assembly 21, and two adjacent rotating shafts 20 are connected through a pulley assembly 22. Both the pulley assembly 21 and the pulley assembly 22 consist of two pulleys and a belt. A fan 23 is fixedly sleeved on the outside of the rotating shaft 20.

[0025] Multiple spray pipes 25 are fixedly installed on the side wall of the ventilation duct 1. The ends of the multiple spray pipes 25 are fixedly connected to nozzles 26. The nozzles 26 can spray disinfectant water at regular intervals to prevent harmful bacteria from being transmitted through the air supply device. After the filter element 4 is replaced, the old filter element 4 can also be disinfected by the disinfectant water after leaving the ventilation duct 1 and passing through the nozzles 26, thus preventing infection when collecting the old filter element 4.

[0026] In this invention, when medical staff want to replace the filter element 4, they move the sliding sleeve to insert the pin 27 into the recess 29, and turn on the motor 5. At this time, the motor 5 drives the rotating shaft 7 to rotate through the drive shaft 6 and two bevel gears 8. Under the action of the pulley 9 and belt 10, the support plate 11 on the side wall moves. The support plate 11 pushes the filter element 4 through the push plate 13, so that the filter element 4 moves with the support plate 11 to the outlet. At this time, the nozzle 26 disinfects the old filter element 4, greatly reducing the bacteria attached to its surface. Finally, the old filter element 4 is collected by the machine. The support plate 11 returns to the inlet with the movement of the belt 10. The medical staff puts the new filter element 4 on the support plate 11, which is pushed to the corresponding position by the push plate 13. When the filter element 4 reaches the corresponding position, the squeezing block 14 on the lower side of the support plate 11 squeezes the slider 15. Since the surface of the slider 15 is arc-shaped, it is not affected by the pressure of the pressure plate 14. When the suction is blocked, the squeezing block 14 drives the slider 15 to move downward, so that the pressure plate 16 compacts and fixes the filter element 4, preventing the filter element 4 from moving and misaligning due to excessive suction, which would affect the entire air supply system. Medical staff no longer need to manually touch the filter element 4 to replace it, reducing the risk of the filter element 4 infecting medical staff. The replacement process is also simple and easy to operate. At the same time, the drive shaft 6 also drives the rotating shaft 18 to rotate through the bevel gear 2 19. The rotating shaft 1 18 drives the rotating shaft 20 to rotate through the pulley assembly 21. The rotating shaft 20 drives the rotation of each other through the pulley assembly 22, which in turn drives the fan 23 to rotate. The combined action of multiple fans 23 enhances the suction, allowing the air supply structure to send out gases containing bacteria and viruses, avoiding secondary infection. Moreover, the suction of the air supply device will no longer be weak due to external factors, thus preventing low purification efficiency of the air in the operating room.
