[0032] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0033] like Figure 1-2 As shown, a clean operating room environment isolation protection device provided by the first aspect of the present invention comprises an air supply ceiling 2 installed on the top of an operating room 1, an exhaust device 3 is arranged on the wall, and an air handling device 5 is arranged on one side of the operating room 1;

[0034] The air handling device 5 is divided into an induced draft cavity, a filter cavity and an air supply cavity by a partition. The induced draft cavity is equipped with an induced draft fan 53. The air outlet end of the induced draft fan 53 penetrates into the filter cavity. A coarse efficiency filter 54 and a medium efficiency filter 55 are sequentially arranged in the filter cavity along the gas conveying direction. The air supply end of the medium efficiency filter 55 penetrates into the air supply cavity and is connected to a fresh air air conditioner 56. The output end of the fresh air air conditioner 56 is connected to a heater 57 and a humidifier 58.

[0035] The air intake cavity of the air handling device 5 is connected to the return air terminal seat 51 and the fresh air terminal seat 52, the air supply cavity is connected to the supply air terminal seat 59, the return air terminal seat 51 is connected to the exhaust duct 31 of the exhaust device 3, the supply air terminal seat 59 is connected to the supply air duct 21 of the air supply ceiling 2, and the connection between the air supply ceiling 2 and the supply air duct 21 and the exhaust device 3 and the exhaust duct 31 are all provided with high-efficiency filters 4.

[0036] As an example of air intake and exhaust in the operating room 1: when the air treatment device 5 is working, the induced draft fan 53 draws in external fresh air through the fresh air terminal seat 52, and transports the inhaled gas to the filter chamber for pre-filtration through the coarse-effect filter 54 and the medium-effect filter 55. The treated gas is transported to the fresh air air conditioner 56 in the air supply chamber, and the fresh air air conditioner 56 distributes the gas, and cooperates with the heater 57 and the humidifier 58 to heat and humidify the transported gas. The treated gas is transported to the operating room 1 through the air supply ceiling 2 connected to the air supply pipe 21. During the diffusion process, the input gas pushes the polluted gas in the room to the exhaust channel for discharge. The subsequently exhausted gas flows back to the return air terminal seat 51 of the air treatment device 5 through the exhaust pipe 31, and is input into the operating room 1 again after being processed by the air treatment device 5 to complete the gas circulation.

[0037] It should be noted that the screening levels of the coarse filter 54, the medium filter 55 and the high efficiency filter 4 increase in sequence. The coarse filter is a common plate filter, the medium filter 55 is a bag filter, and the high efficiency filter is used to capture particulate dust and various suspended matter larger than 0.5um, as the terminal filter of various filtration systems.

[0038] It should be added that the high efficiency filter 4 is arranged in the pipes at the air inlet and outlet ends of the operating room to perform terminal filtration on the incoming or exhausted gas.

[0039] like Figure 3-6 As shown, this is an example of pre-processing to find the best exhaust position:

[0040] A reserved groove is provided on the outer wall of the operating room 1, and a temporary exhaust mechanism is arranged on the reserved groove. The temporary exhaust mechanism includes a temporary track 61 symmetrically installed on the upper and lower sides of the wall groove, and a plurality of A clamps 62 and B clamps 63 are respectively installed on the upper and lower temporary tracks 61 to match them. The end surfaces of the A clamps 62 and B clamps 63 penetrating the inner wall are installed with matching wall panels 64 or exhaust devices 3. The exhaust device 3 includes an exhaust grille 32 and an exhaust pipe 31. The specifications of the exhaust grille 32 are the same as those of the wall panel 64. The difference is that a hollow ventilation groove is provided on the exhaust grille 32, and the exhaust pipe 31 is connected to the rear of the exhaust grille 32. A high-efficiency filter 4 is installed at the connection between the exhaust pipe 31 and the exhaust grille 32.

[0041] It should be noted that the wall corners of the operating room 1 are of an arc-shaped structure. The arc-shaped corner design can prevent dirty gas from being retained at the corners, thereby solving the problem of ventilation dead spots at right-angle corners.

[0042] In this embodiment, a temporary track 61 is arranged on the outer wall, and a wall panel 64 or an exhaust device 3 attached to the inner wall is installed between the A clamp block 62 and the B clamp block 63 through cooperation between the two. The wall panel 64 and the exhaust device 3 are modularly designed, and the position of the exhaust device 3 on the wall can be switched in sequence. It is only necessary to remove the wall panel 64 at the corresponding position from the clamp block and install the exhaust device 3 at the clamp block. The advantage of the design is that the optimal exhaust position can be determined according to the working efficiency of the exhaust device 3 at different positions in the exhaust state, and the operating room 1 is always in a closed state.

[0043] Furthermore, when the exhaust device 3 is adjusted in position, the exhaust duct 31 is always connected to the return air terminal 51 of the air handling device 5 , so that normal air supply and exhaust can be performed in the operating room 1 .

[0044] In order to assist the sealing of the wall panels 64 and the exhaust grille 32 when they are installed in the wall grooves, further, sealing strips are installed on the adjacent wall panels 64 or the attached end surfaces of the wall panels 64 and the exhaust grille 32 to assist in gap sealing.

[0045] like Figure 5 As shown, a wind speed and direction detecting device 7 is provided on one side of the exhaust device 3, and the wind speed and direction detecting device 7 includes a base 71 installed in the operating room 1, a detection host 72 is installed above the base 71, a vertical pole 73 is installed on the top of the detection host 72, and a ring frame 74 is provided on the outer wall of the vertical pole 73, and a wind cup sensor 75 connected to the signal of the detection host 72 is installed at the protruding end of the ring frame 74.

[0046] As a detection example for finding the optimal exhaust position: when air is supplied and exhausted in the operating room 1, an air duct is formed between the air supply ceiling 2 and the exhaust device 3, and the wind cup sensor 75 detects the wind speed and wind direction, and transmits the data to the detection host 72 for recording. According to the position adjustment of the exhaust device 3 at the temporary track 61 slotted in the wall, the wind speed and direction data after switching the position are recorded in turn, the test data is analyzed to confirm the optimal exhaust position, and the optimal exhaust position is recorded.

[0047] A second aspect of the present invention provides a method for isolating and protecting a clean operating room environment, comprising the following steps:

[0048] Step 1: Build an operating room 1, install an air supply ceiling 2 for supplying air on the top of the operating room 1, and connect the air supply ceiling 2 to an air treatment device 5 for assisting in delivering air to the operating room 1 through an air supply pipe 21;

[0049] Step 2: grooves are made on the side wall of the operating room 1, and a temporary exhaust mechanism is set at the grooves. The exhaust pipe 31 on the exhaust device 3 is connected to the air handling device 5. The exhaust device 3 and the air supply ceiling 2 cooperate with the pipeline to connect the operating room 1 and the air handling device 5. The air handling device 5 assists the operating room 1 to exchange indoor and outdoor air, and several wind speed and direction detection devices 7 are set at the temporary exhaust mechanism to simulate the exhaust rate under different opening positions of the exhaust device 3;

[0050] Step 3: Determine the best position of the exhaust device 3 by comparing the data recorded by the wind speed and wind direction detection device 7 at different exhaust device 3 opening positions;

[0051] Step 4: dismantle the temporary exhaust mechanism, seal the wall slots, and reserve an exhaust device 3 for exhaust. After installing the exhaust device 3 at the designated location, the construction of the operating room 1 is completed.

[0052] Embodiment 1: When performing the construction operation of step 4, it is necessary to remove the exhaust mechanism blocking slot, reserve the exhaust device 3 installation slot, and install the exhaust device 3 at the designated position.

[0053] Embodiment 2: There is no need to perform the construction operation of step 4. The exhaust device 3 is installed at the optimal recording position, and the wall panel 64 is installed at the remaining slotted position for sealing. The adjacent wall panels 64 or the adjacent wall panels 64 and the exhaust duct 31 are connected by the mounting plate. The temporary exhaust mechanism can be used as a normal exhaust mechanism without the need for secondary sealing construction of the wall.

[0054] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
