Description

Technical Field

[0001] The utility model relates to the technical field of fresh air systems, in particular to a fresh air circulation purification system for operating rooms. Background Technique

[0002] The fresh air system in the operating room is different from the traditional indoor fresh air system. Since the air in the operating room must be kept clean and strict requirements are imposed on pathogenic bacteria, the control of the bacteria content rate is one of the most important indicators of the fresh air in the operating room.

[0003] The conventional fresh air system is an independent air treatment system composed of a supply air system and an exhaust air system. It is divided into two types: a ducted fresh air system and a ductless fresh air system. The ducted fresh air system is composed of a fresh air fan and duct fittings. The outdoor air is purified by the fresh air fan and introduced into the room, and the indoor air is discharged through the duct. The ductless fresh air system is composed of a fresh air fan, and the outdoor air is also purified by the fresh air fan and introduced into the room. Relatively speaking, the ducted fresh air system is more suitable for industrial or large-area office areas due to the large amount of work, while the ductless fresh air system is more suitable for home use because of its convenient installation.

[0004] For the operating room, whether it is a ducted fresh air system or a ductless fresh air system, air is introduced from the outside to the inside; and there are many uncertainties in the bacteria content in the outdoor air; it is not suitable for the operating room.

[0005] At present, in the fresh air systems widely used in operating rooms, fresh air needs to be introduced into the room after multiple sterilization treatment processes; and the bacteria content in the indoor air is relatively low, approaching the air index of a nearly aseptic environment; directly discharging it outdoors is relatively wasteful.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.

[0042] Please refer to Figures 1 - 9 , in the embodiment of the present invention, a fresh air circulation purification system for an operating room includes a housing 1 and a partition 2 disposed inside the housing 1 that divides the housing 1 into two independent chambers. A hollow box 3 is slidably disposed on one side of the partition 2 inside the housing 1, and a liquid storage tank 4 is disposed below the hollow box 3 inside the housing 1;

[0043] A circulation mechanism is arranged inside the housing 1 and on the other side of the partition 2. The circulation mechanism is respectively connected to the hollow box 3 and the liquid storage tank 4. At the same time, the hollow box 3 is connected to the circulation mechanism through a transmission structure. The transmission structure will drive the hollow box 3 to horizontally reciprocate above the liquid storage tank 4 when the circulation mechanism operates. And the circulation mechanism will also spray the disinfectant water contained in the liquid storage tank 4 from the hollow box 3, so as to form a shower curtain between the hollow box 3 and the liquid storage tank 4.

[0044] An air guiding component is also arranged inside the housing 1 and on the other side of the partition 2. The air guiding component is connected to the circulation mechanism. The air guiding component will suck the air in the operating room into the housing 1 and discharge it after disinfecting through the shower curtain when the circulation mechanism operates.

[0045] In this solution, under the action of the circulation mechanism, a disinfectant liquid shower curtain is formed between the hollow box 3 and the liquid storage tank 4. And the hollow box 3 will horizontally reciprocate under the cooperation of the transmission structure and the circulation mechanism, thereby increasing the area and density of the shower curtain. At the same time, the air guiding component will, under the action of the circulation mechanism, make the air in the operating room be discharged into the operating room again after being disinfected through the shower curtain, forming continuous circulation of the air in the operating room.

[0046] In this application, the air with a relatively low bacteria content in the operating room can be sterilized and recycled, avoiding the traditional multi-channel sterilization treatment of the many uncertain air outdoors and then introducing it into the operating room. While improving the utilization rate of the air with a relatively low bacteria content in the operating room, it also reduces the difficulty of purifying the air.

[0047] As a further solution of the utility model, the circulation mechanism includes a pump 5 arranged inside the housing 1 and a liquid inlet pipe 6 arranged on the partition 2. One end of the liquid inlet pipe 6 is located at the inner bottom of the liquid storage tank 4 and the other end is communicated with the liquid inlet of the pump 5.

[0048] The top end of the hollow box 3 is communicated with a liquid outlet pipe 7. A flexible hose 8 is arranged inside the housing 1. One end of the flexible hose 8 is hermetically and slidably communicated with one end of the liquid outlet pipe 7 and the other end is communicated with the liquid outlet of the pump 5. A plurality of liquid outlet holes 301 are opened at the bottom end of the hollow box 3.

[0049] In this embodiment, when the pump 5 is started, the pump 5 will use the liquid inlet pipe 6, the flexible hose 8 and the liquid outlet pipe 7 to extract the disinfectant liquid contained in the liquid storage tank 4 into the hollow box 3 and then discharge it through the plurality of liquid outlet holes 301 at the bottom of the hollow box 3. During this process, a disinfectant liquid shower curtain is formed between the hollow box 3 and the liquid storage tank 4.

[0051] A rotating shaft 11 is rotatably disposed on the bracket 9, and one end of the rotating shaft 11 is connected to the output end of the pump 5.

[0052] In this embodiment, since the rotating shaft 11 is rotatably disposed on the bracket 9 and one end is connected to the output end of the pump 5, therefore, when the pump 5 is started, the rotating shaft 11 will rotate accordingly;

[0053] Since the moving rod 10 is slidably disposed horizontally on the partition 2 and one end of the moving rod 10 is connected to one end of the hollow box 3, therefore, when the moving rod 10 moves horizontally back and forth, the hollow box 3 will move horizontally back and forth accordingly;

[0054] Also, because one end of the hose 8 is hermetically and slidably communicated with one end of the liquid outlet pipe 7 and the other end is communicated with the liquid outlet of the pump 5, therefore, during the horizontal reciprocating movement of the hollow box 3, the liquid outlet pipe 7 and the hose 8 will be driven to slide cooperatively with each other.

[0064] As a further solution of the present utility model, a T-shaped chute 101 is opened at the inner top of the housing 1, and a T-shaped slider 302 is provided at the top of the hollow box 3. The T-shaped slider 302 is located inside the T-shaped chute 101 and is slidably matched with each other;

[0065] A circulating air inlet 102 is opened on one side of the housing 1 close to the liquid storage tank 4, and a plurality of louvers 103 are arranged in the circulating air inlet 102.

[0066] In this embodiment, since the T-shaped slider 302 is located inside the T-shaped chute 101 and is slidably matched with each other, the hollow box 3 is slidably arranged at the inner top of the housing 1;

[0067] When the impeller 17 starts to rotate, the air in the operating room will enter the housing 1 through the circulating air inlet 102 provided with a plurality of louvers 103, and pass through the disinfectant liquid curtain formed in the housing 1 to complete purification.
