Description

Technical Field

[0001] The invention relates to the technical field of medical clean rooms, and in particular to a clean operating room comfort control and purification integrated system. Background Art

[0002] At present, in the purification system of hospital operating rooms, in order to achieve the regulation of indoor temperature and humidity, air cooling is usually adopted, that is, a static pressure box is set on the top of the operating room, and air is supplied through the laminar static pressure box to achieve indoor air convection, thereby taking away the heat and humidity generated in the operating room.

[0003] In the above adjustment process, the temperature at the laminar flow static pressure box outlet is usually 5-7℃ lower than the temperature at other locations in the room. Low temperature wind will have the following effects on the clean operating room:

[0004] (1) Changes in airflow patterns: Low-temperature air supply will form a larger temperature gradient, causing the airflow to sink faster, which may disrupt the original laminar state and cause local turbulence, thus affecting the stability and uniformity of the airflow;

[0005] (2) Temperature stratification: Due to the large difference between the air supply and indoor temperature, obvious temperature stratification will occur indoors. The temperature of the area close to the air supply outlet is lower, while the temperature of the area far from the air supply outlet is relatively higher. This temperature stratification may affect the health of medical staff and have a certain impact on surgical operations.

[0006] (3) Changes in air flow velocity distribution: Low-temperature air supply will increase the air flow velocity in certain areas, especially near the air supply outlet, which may cause local wind speed to be too high and affect the air flow stability in the surgical area.

[0007] (4) Deflection of airflow direction: A large temperature difference may cause the airflow to deflect during the flow process, deviating from the originally designed flow direction, thereby affecting the removal effect of pollutants.

[0008] (5) Local cooling effect: In the surgical area, the low-temperature airflow may directly contact the patient and surgical instruments, causing local cooling, which may adversely affect the patient's body temperature regulation and may also affect the performance of certain instruments.

[0009] Therefore, in response to the above technical problems, how to design a clean operating room comfort control and purification integrated system that improves the comfort of doctors and patients, enhances the cleanliness of the operating room and reduces the cost of use is a technical problem that technical personnel in this field need to solve.

[0033] Embodiment 1

[0034] like Figure 1As shown, the present invention provides a clean operating room comfort control and purification integrated system, including a purification module, a radiation module and an intelligent control module. The purification module and the radiation module are electrically connected to the intelligent control module located in the operating room 10 respectively. The working state of other modules can be automatically and reasonably adjusted through the intelligent control module. The intelligent control module includes a second temperature and humidity sensor 21 and a cleanliness sensor arranged in the operating room 10, which detects the environmental data in the operating room 10 in real time. Each sensor transmits the collected data to the main control unit for signal processing, and makes corresponding active control according to the preset control strategy and the received environmental data. Since the intelligent control modules all adopt the relatively mature existing technologies, no more details will be given here.

[0035] In this embodiment, the purification module includes a circulation unit 1, the air inlet side of the circulation unit 1 is provided with a first return air inlet 2 and a fresh air inlet 3, and the air outlet side is provided with a first air outlet 4. The fresh air inlet 21 is used to blow fresh air from the outside into the circulation unit 1 to ensure that fresh air always flows into the operating room.

[0036] The circulation unit 1 is provided with a first temperature and humidity sensor 5, a first surface cooler 6 and an electric reheater 7, wherein the first temperature and humidity sensor 5 is provided on the side close to the first return air inlet 2 and the fresh air inlet 3. The first air outlet 4 is connected to the laminar ceiling static pressure box 9 located at the top of the operating room 10 through the first air supply duct 8. A return air outlet 11 is provided on the side of the operating room 10, and the return air outlet 11 is connected to the first return air inlet 2 through the first return air duct 12. A first exhaust outlet 22 is provided on one side of the operating room 10, and the first exhaust outlet 22 is connected to the second exhaust outlet 25 through the exhaust duct 23. A silent exhaust fan 24 is installed on the exhaust duct 23 to control the exhaust rate of the air in the operating room 10.

[0037] A circulating fan is provided inside the circulation unit 1 to provide power for air circulation. The first temperature and humidity sensor 5 detects the temperature and humidity of the mixed air in real time. The intelligent control module determines whether to dehumidify or humidify or heat or cool the mixed air according to the data of the first temperature and humidity sensor 5. After being processed by the first surface cooler 6 and the electric reheater 7, the air reaches the parameters required by the operating room 10 and is sent to the operating room 10 through the circulation pipeline and the laminar ceiling static pressure box 9. A part of the air in the operating room 10 is discharged to the outside through the exhaust duct 23, thereby completing the primary air processing process.

[0038] The radiation module is a closed system, without outdoor air supply or exhaust. The radiation module includes a variable temperature air conditioning unit 13. The air inlet side of the variable temperature air conditioning unit 13 is provided with a second return air inlet 14, and the air outlet side is provided with a second air outlet 15. The variable temperature air conditioning unit 13 is provided with a second surface cooler 16 for adjusting the temperature of the internal air. The second air outlet 15 is connected to the air inlet end of the air circulation radiation plate 19 through the second air supply duct 17. The radiation module uses the air circulation radiation plate 19 to perform heat exchange with the air in the operating room 10. The air inlet end of the air circulation radiation plate 19 is installed with a temperature sensor 18, and the air outlet end of the air circulation radiation plate 19 is connected to the second return air inlet 14 through the second return air duct 20.

[0039] The temperature sensor 18 monitors the temperature of the gas entering the air circulation radiation panel 19 in real time. The second temperature and humidity sensor 21 monitors the temperature and humidity data in the operating room 10 in real time (responsible for preventing condensation on the panel surface). The collected environmental information is sent to the intelligent control module for processing. The intelligent control module controls the second surface cooler 16 in the variable temperature air-conditioning unit 13 to adjust the circulating air to a reasonable temperature (the temperature range after treatment is 15-19°C) and send it to the air circulation radiation panel 19. The variable temperature air-conditioning unit 13 is also provided with a circulating fan to provide power for air circulation. The air after heat exchange returns to the variable temperature air-conditioning unit 13 through the second return air duct 20, and is processed again by the second surface cooler 16. When the temperature parameters meet the requirements, it is sent to the air circulation radiation panel 19 through the second supply air duct 17, thereby completing a processing process. The specific control process is as follows: Figure 2 shown.

[0040] During the operation of the purification module and the radiation module, the intelligent control system will adjust the air supply temperature of the circulation unit 1 and the variable temperature air conditioning unit 13 according to various position sensors.

[0041] like Figure 3 As shown, the air circulation radiation panel includes a shell 26, a frame plate 33, a spoiler 36 and an air guide plate 37, wherein the shell 26 is sealed all around and hollow in the middle, and can replace the wall plate or ceiling plate of the existing operating room 10. The frame plate 33, the spoiler 36 and the air guide plate 37 are all arranged in the shell 26. The shell 26 includes a rear panel 27 mounted on the keel, and the front side of the rear panel 27 is sealed and connected to the front panel 28 through a metal frame, as shown in FIG. Figure 4 shown.

[0042] In this embodiment, a rear cover 29 is fastened to the rear panel 27 to seal therewith, and an air inlet channel is formed between the rear cover 29 and the rear panel 27. A radiation panel air inlet 30 is provided on the rear cover 29. In this embodiment, a plurality of air inlet branches 32 and a radiation panel return air outlet 31 are provided on the rear panel 27. Figure 5 shown.

[0043] The radiation plate air inlet 30 is externally connected to the variable temperature air conditioning unit 13, and the variable temperature air conditioning unit 13 is also connected to the radiation plate return air outlet 31 through a pipeline, thereby forming a complete circulating air duct to realize the process of circulating conduction and temperature regulation. Among them, the rear cover 29 covers all the air inlet branches 32. Under the action of the air inlet cavity, the circulating air is evenly distributed to each air inlet branch 32, so that the heat radiation efficiency of each air cavity is equivalent. The air inlet branch 32 is used to introduce circulating air into the shell 26, and after the circulating air completes the radiation heat transfer in the shell 26, it is finally discharged from the shell 26 through the radiation plate return air outlet 31.

[0044] like Figure 6 As shown, the skeleton plate 33 includes a vertical plate 34 and a horizontal plate 35 that divide the interior of the shell 26 into multiple air cavities. The two ends of the vertical plate 34 and the horizontal plate 35 are connected to the inner walls of the top and bottom of the shell 26. The vertical plate 34 and the horizontal plate 35 cooperate with the shell 26 to form multiple independent air cavities. Each air cavity corresponds to an air inlet branch 32, and circulating air can be injected into the air cavity through the air inlet branch 32. Similarly, each air cavity also corresponds to a return air branch 40 set on the vertical plate 34. After the circulating air completes radiation heat transfer in the air cavity, it is discharged from the return air branch 40.

[0045] In this embodiment, the number of the vertical plates 34 is set to two, and the number of the horizontal plates 35 is set to four, so that the housing 26 is divided into six independent air cavities and a return air cavity 38 between the two vertical plates 34, and the radiation plate return air port 31 is opened on one side of the return air cavity 38. It should be noted that the number of the vertical plates 34 and the horizontal plates 35 can be adjusted accordingly according to actual needs, and it is only necessary to ensure that there are independent air cavities and return air cavities 38, which can be selected according to the actual size of the housing 26 and the effect of radiation heat transfer.

[0046] Since the return air outlet 40 is arranged on the vertical plate 34, the circulating air of all air cavities can enter the return air cavity 38 through the corresponding return air outlet 40. The radiation plate return air outlet 31 is arranged on the rear panel 27 corresponding to the position of the return air cavity 38, so that the circulating air is discharged from the radiation plate return air outlet 31 after being collected.

[0047] The spoiler 36 is arranged in the air cavity, and the number is at least one. When the circulating air passes through the spoiler 36, a spoiler area is formed at the spoiler 36, thereby increasing the efficiency of radiation heat transfer. In this embodiment, three spoilers 36 are arranged in each air cavity, and each spoiler 36 is arranged parallel to the horizontal plate 35 and has a ventilation hole 39. The shape of the ventilation hole 39 can be square, circular or any other shape according to actual needs. In this embodiment, a square ventilation hole 39 is used.

[0048] Considering that when the circulating air in the air cavity is discharged to the return air port 31 of the radiation plate, the closer the distance, the faster the discharge time. Therefore, in order to fully utilize the thermal radiation performance of the circulating air, in this embodiment, the opening area of ​​the ventilation holes 39 in the air cavity close to the return air port 31 of the radiation plate is smaller than the opening area of ​​the ventilation holes 39 in the air cavity far from the return air port 31 of the radiation plate, thereby increasing the wind resistance in the air cavity close to the return air port 31 of the radiation plate and slowing down the discharge efficiency of the circulating air in the air cavity. Of course, it can also be set accordingly by different numbers of openings, and it only needs to be selected according to needs during actual application.

[0049] The air guide plate 37 is tilted in the air cavity and corresponds to the position of the air inlet branch 32. When the circulating air enters the air cavity, it first contacts the air guide plate 37, thereby changing the wind direction of the circulating air and causing it to flow toward the spoiler 36, thereby improving the flow efficiency of the circulating air, and finally being discharged from the return air branch 40, and finally converging to the return air port 31 of the radiation plate, and discharged outside the housing 26. In this embodiment, the air guide plate 37 and the return air branch 40 are diagonally arranged, so that the distance between the air guide plate 37 and the return air branch 40 is as large as possible, which can effectively increase the flow distance of the circulating air in the air cavity, thereby making full use of the thermal radiation performance of the circulating air.

[0050] After the circulating air enters the air cavity, it flows in each air cavity, and as the circulating air continues to flow into the air cavity, the circulating air that completes the radiation heat exchange is collected from the return air branch 40 to the return air cavity 38, and finally discharged from the radiation plate return air port 31, and enters the variable temperature air conditioning unit 13, and circulates again.

[0051] Therefore, the present invention adopts the above-mentioned clean operating room comfort control and purification integrated system to make the temperature and airflow of the circulating air in the operating room more uniform, and solve the problem of harm to the health of doctors and patients caused by low-temperature wind.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
