Description

Technical Field

[0001] The utility model relates to the field of operating room air purification, in particular to a one-to-many operating room air purification system. Background Art

[0002] In the traditional fresh air purification scheme for clean operating rooms, 80% of the air inside the operating room relies on internal circulation purification, and the remaining 20% ​​is purified by fresh air. At the same time, the pressure difference inside the clean operating room is guaranteed by an appropriate amount of fresh air. In a 10,000-level clean operating room, one set of air conditioning units can be used with 2-3 clean operating rooms, which is the common one-to-two and one-to-three schemes. During the implementation of the scheme, after confirming the number of rooms that the air conditioning unit needs to support, the air volume of multiple clean operating rooms is adjusted through manual air valves. When the air volume is adjusted to the appropriate level, the position of the manual air valve is fixed. In this way, once the unit is turned on, multiple rooms will enter the working state at the same time, and they cannot be controlled or adjusted individually, which is inconvenient to use.

[0069] In this embodiment, the operating room includes a first operating room 7 and a second operating room 8. It can be understood here that the first operating room 7 and the second operating room 8 are independent of each other, but share the same air purification system. It can be understood that the operating room can also include a third operating room and a fourth operating room. In this embodiment, two operating rooms share one air purification system for explanation.

[0070] The air conditioning unit 1 is used to continuously provide pure air that meets the operating room conditions to the operating room, including filtering, purifying, and adjusting the temperature and humidity of the circulating gas in the operating room and the outdoor fresh air. In this embodiment, the pipeline assembly 2 can be understood as a pipeline for connecting air, specifically as Figure 1 As shown, an air conditioning unit 1 is arranged between the first pipeline 21 and the second pipeline 22, one end of the first pipeline 21 is connected to the input end of the air conditioning unit 1, and the other end of the first pipeline 21 is connected to the outside, where the outside can be understood as an external environment that can continuously provide fresh air. One end of the second pipeline 22 is connected to the air conditioning unit 1 and to the output end of the air conditioning unit 1, and is used to transport the pure air generated by the air conditioning unit 1, wherein the first branch pipe 23 and the second branch pipe 24 are respectively connected to the other end of the second pipeline 22, and the pure air in the second pipeline 22 is respectively passed into the first operating room 7 and the second operating room 8 through the first branch pipe 23 and the second branch pipe 24.

[0071] In this embodiment, the wind control component 3 is used to adjust the air volume in the pipeline component 2. Specifically, the wind control component 3 includes a first exhaust valve 34 and a second exhaust valve 35. The first exhaust valve 34 and the second exhaust valve 35 are preferably electric air valves, and the opening sizes of the first exhaust valve 34 and the second exhaust valve 35 can be set according to actual needs. The wind control component 3 also includes a first air volume sensor 31, a second air volume sensor 32 and a third air volume sensor 33, wherein the first air volume sensor 31 is arranged at the output end of the first exhaust valve 34 and at the connection between the first branch pipe 23 and the first operating room 7, and the second air volume sensor 32 is arranged at the output end of the second exhaust valve 35 and at the connection between the second branch pipe and the second operating room 8; this setting method can enable the first air volume sensor 31 to detect the air volume size of the first exhaust valve 34, thereby realizing feedback on the opening of the first exhaust valve 34, and similarly, the second air volume sensor 32 detects the air volume size of the second exhaust valve 35, thereby realizing feedback on the opening of the second exhaust valve 35. The third air volume sensor 33 is disposed at the connection point between the second pipeline 22 and the air conditioning unit 1 , and the third air volume sensor 33 can detect the air volume output from the air conditioning unit 1 to the second pipeline 22 .

[0072] The present embodiment also provides a control unit, which is electrically connected to the first air volume sensor 31, the first exhaust valve 34, the second exhaust valve 35, the first air volume sensor 31, the second air volume sensor 32, the third air volume sensor 33 and the air conditioning unit 1 respectively. Specifically, the control unit can obtain the real-time air flow in the current first operating room 7 through the first air volume sensor 31. When the first exhaust valve 34 of the first operating room 7 is closed, the air volume detected by the first air volume sensor 31 is less than the predetermined value range, indicating that the current first operating room 7 is in an unused state; thereafter, the control unit detects the opening state of the current second exhaust valve 35 through the second air volume sensor 32, and then obtains the use state of the second operating room 8. Taking the second operating room 8 still in use and the first operating room 7 not in use as an example, at this time, the control unit obtains the real-time air volume output of the current air-conditioning unit 1 through the third air volume sensor 33. If the air volume output of the air-conditioning unit 1 is within the air volume range for simultaneously delivering air to two operating rooms, it indicates that the current operating state of the air-conditioning unit 1 does not match the actual required operating state of the air-conditioning unit 1. The control unit will send a control signal to the air-conditioning unit 1 to reduce the operating power of the air-conditioning unit 1, thereby realizing the adjustment of the air volume output of the air-conditioning unit 1.

[0073] The present embodiment realizes the adjustment of the air-conditioning unit 1 in a one-to-many usage scenario. By adding air volume sensors and exhaust valves at the air supply outlets of multiple operating rooms, the individual control of the air volumes of multiple operating rooms is realized. In addition, the real-time usage status of the multiple operating rooms can be known according to each air volume sensor, and the operating power of the air-conditioning unit 1 can be reasonably adjusted, thereby realizing energy-saving adjustment of the air-conditioning unit 1.

[0074] See also Figure 1 In some embodiments, it also includes a first purification component 4 and a second purification component 5. The first purification component 4 is arranged at the connection between the first branch pipe 23 and the first operating room 7; the second purification component 5 is arranged at the connection between the second branch pipe 24 and the second operating room 8.

[0075] In this embodiment, the first purification component 4 is arranged at the connection between the first branch pipe 23 and the first operating room 7, and can further purify the air input into the first operating room 7 to improve the air quality. Similarly, the second purification component 5 is arranged at the connection between the second branch pipe 24 and the second operating room 8, and can further purify the air input into the second operating room 8.

[0076] See also Figure 1 and Figure 2 In some embodiments, the first purification component 4 includes a first static pressure box 41, a first active composite particle generator 42 and a first flow equalizing network 43. The first static pressure box 41 has a first inlet and a first outlet. The first inlet is connected to the first branch pipe 23, and the first outlet is connected to the first operating room 7; the first active composite particle generator 42 is arranged at the first inlet; the first flow equalizing network 43 is arranged at the first outlet.

[0077] In this embodiment, the first static pressure box 41 can be understood as a thin-walled structure with a cavity, and the specific shape of the first static pressure box 41 can be set according to actual needs to achieve the best noise reduction effect when the airflow converges. The first static pressure box 41 includes a first inlet and a first outlet, the first inlet is the opening for air to flow into the first static pressure box 41, and the first outlet is the opening for air to flow out of the first static pressure box 41, wherein the first outlet is connected to the first operating room 7, and the first inlet is connected to the first branch pipe 23, then the purified air is input from the first branch pipe 23 into the first static pressure box 41, and then input into the first operating room 7 through the first static pressure box 41.

[0078] The present embodiment also provides a first active composite particle generator 42, which is disposed in the first static pressure box 41 and at the first inlet. When the purified air at the first branch pipe 23 is input into the first static pressure box 41, the airflow driven by it will disperse the active composite particles generated by the first active composite particle generator 42 into the air, and then input into the first operating room 7 through the first flow-equalizing net 43. In the present embodiment, the first flow-equalizing net 43 is disposed at the first outlet, which can evenly guide the airflow in the first static pressure box 41 so that it is evenly dispersed in the first operating room 7.

[0079] Specifically, the first active composite particle generator 42 includes a discharge electrode and a high-voltage electrode sheet, wherein the shapes of the discharge electrode and the high-voltage electrode sheet include a circular electrode, a needle-shaped electrode and a peach-shaped electrode. The specific structure can be referred to in the publication number CN218388045U "An Active Composite Particle Generator", wherein the PN junction under the discharge electrode condenses water molecules in the air to the surface of the discharge electrode to form concentrated water droplets through the thermoelectric effect. After generating high voltage, the high-voltage electrode sheet pulls the water droplets on the surface of the discharge electrode upward to the tip to form a Taylor cone and generate corona discharge, ionizing to generate active composite particles. When using a needle-shaped electrode, there is less water at the top, and it is easy to produce a large amount of ozone; it is difficult to form a Taylor cone when using a circular electrode; and the peach-shaped electrode is easier to form a Taylor cone of discharge and produces less ozone because it meets the Taylor curve.

[0080] The first active composite particle generator 42 can generate active oxides, such as oxygen ions, superoxide anions, hydroxyl radicals, etc. These active oxides have strong oxidizing properties and bactericidal effects, and can destroy the cell walls and membranes of microorganisms such as bacteria, viruses, and molds, thereby achieving the effect of killing microorganisms. The active oxides and negative ions generated by the first active composite particle generator 42 can react chemically with harmful gases, decomposing them into harmless substances or converting them into a form that is easy to handle. For example, the first active composite particle generator 4224 can decompose volatile organic compounds such as formaldehyde, benzene, and toluene into carbon dioxide and water, thereby reducing the concentration of harmful gases in the air.

[0081] By providing the first purification component 4 , active composite particles can be added to the purified air, so that the gas in the first operating room 7 has the sterilization effect of the active composite particles, further improving the air purity in the first operating room 7 .

[0082] See also Figure 1 and Figure 2 In some embodiments, the first branch pipe 23 includes a first main portion 233, a first branch portion 231 and a second branch portion 232. The number of first inlets is two and they are relatively arranged on both sides of the first static pressure box 41. The first branch portion 231 is connected to one of the first inlets, and the second branch portion 232 is connected to the other first inlet. The first main portion 233 is connected to the first branch portion 231 and the second branch portion 232 respectively. The first exhaust valve 34 and the first air volume sensor 31 are arranged on the first main portion 233 in sequence along the wind direction.

[0083] Furthermore, the first main part 233 and the first branch 231 and the second branch 232 form a three-way structure, then the first branch pipe 23 is an F-shaped structure or a Y-shaped structure, and the first static pressure box 41 is arranged between the first branch 231 and the second branch 232; the first inlet on the first static pressure box 41 can be multiple, preferably two, one of the first inlets is connected to the first branch 231, and the second branch 232 is connected to the other first inlet, then the purified air is introduced into the first static pressure box 41 through the two first inlets respectively, and then flows out from the first outlet after mixing.

[0084] The method shown in this embodiment can increase the number of first active composite particle generators 42, thereby increasing the concentration of active composite particles in the purified air, so as to achieve the optimal sterilization effect.
