Abstract
Description
Technical Field
[0001] The patent of this invention relates to the field of laminar flow ceiling technology, specifically to a laminar flow ceiling with zoned and different temperature air supply in an operating room. Background Art
[0002] According to hospital construction standards, high-end operating rooms are required to have a localized laminar flow ventilation system directly above the operating table. This system has two primary functions: first, it rapidly replaces all contaminated air within the protected area with dust-free, sterile air, ensuring a clean and sterile surgical site; second, it prevents less clean air from entering the protected area from outside the laminar flow zone.
[0003] In actual use, existing laminar air supply devices have exposed two major shortcomings: first, the air supply temperature cannot meet the needs of both doctors and patients; second, the laminar air supply has poor anti-interference ability. A laminar air supply ceiling is disclosed in the utility model patent publication number CN215112925U (hereinafter referred to as "Prior Art 1"). The laminar air supply ceiling provided in Prior Art 1 can form an effective barrier at the edge of the air supply area while supplying air, shielding the mainstream area from external contamination. This ensures the cleanliness and stability of the air in the mainstream area during long-term use, greatly improves the utilization rate of clean airflow, and requires no maintenance or cleaning, greatly reducing the cleaning workload of medical staff after surgery.
[0004] The problem solved in prior art 1 is to prevent external air from polluting the air in the mainstream area and to ensure the cleanliness and stability of the air in the mainstream area. At present, the laminar air supply in the operating room is delivered with uniform temperature, humidity and wind speed, and gives priority to satisfying the comfort of the surgical staff to improve the efficiency of the operation. The surgical staff wear a full set of sterile clothing and have high work intensity, so they need a lower temperature. However, such an air supply temperature is too low for the patient and can easily cause hypothermia in the patient. Therefore, the patient needs a higher temperature to maintain himself in a comfortable state. Prior art 1 did not pay attention to the needs of doctors and patients for the air supply temperature, so no relevant settings were made to enable the laminar flow ceiling to blow out airflows of different temperatures.
[0005] Invention patent content
[0006] In view of this, our company has designed a laminar flow ceiling with zoned and differential temperature air supply in the operating room to solve the problem that existing technology cannot simultaneously meet the different temperature requirements of patients and surgical staff.
[0007] The technical solution of the present invention is as follows:
[0008] The invention discloses a laminar flow ceiling with zoned different-temperature air supply in an operating room, comprising a high-temperature air supply area and a low-temperature air supply area, which form a laminar flow ceiling box.
[0009] The laminar flow ceiling box includes four boxes, and partitions are provided in the boxes. The partitions separate the laminar flow ceiling box into a high-temperature air supply area and a low-temperature air supply area. The high-temperature air supply area is set in the middle of the laminar flow ceiling box, and the low-temperature air supply area is set on both sides of the laminar flow ceiling box; a fixed base is provided in the laminar flow ceiling box, and the fixed base is set at the connection of the four boxes.
[0010] Air inlets and air outlet surfaces are provided in the high-temperature air supply area and the low-temperature air supply area, and high-efficiency filters are provided in the high-temperature air supply area and the low-temperature air supply area; the high-efficiency filters are provided above the air outlet surfaces, and a flow balancing layer is provided between the high-efficiency filters and the air outlet surfaces. The flow balancing layer makes the air delivered from the high-temperature air supply area and the low-temperature air supply area more uniform.
[0011] In a preferred technical solution, a fixed structure is provided in the box body, and the fixed structure includes a load-bearing plate, a first support frame, a second support frame, a fixed ring, a square tube, a first horizontal plate and a second horizontal plate; the fixed ring connects the first horizontal plate and the second horizontal plate, the square tube and the first support frame are arranged on the load-bearing plate, the second support frame is connected to the first support frame, and the second support frame is connected to the first horizontal plate.
[0012] In a preferred technical solution, an operating room partitioned temperature-differentiated air supply laminar flow ceiling also includes a support plate, which is arranged below the air inlet, connected to the inner wall of the box, and a high-efficiency filter is fixed on the support plate.
[0013] In a preferred technical solution, a central hole is provided on the fixed base, and a shadowless lamp is installed in the central hole.
[0014] In a preferred technical solution, a connecting piece is provided on the air inlet, and the connecting piece is used to extend the air inlet.
[0015] In a preferred technical solution, a bracket is provided on the low-temperature air supply area, the cross-section of the bracket is "U"-shaped, and a mounting hole is provided on the bracket. The bracket is used to install the different-temperature air supply laminar ceiling.
[0016] In a preferred technical solution, a plurality of ventilation holes are provided on the air outlet surface, and the ventilation holes are evenly distributed on the air outlet surface.
[0017] In a preferred technical solution, the high-temperature air supply area and the low-temperature air supply area are made of materials with fireproof or antibacterial properties.
[0018] The beneficial effects of the present invention are:
[0019] The patent of this invention sets up a high-temperature air supply area and a low-temperature air supply area in the laminar flow ceiling. During the operation, the two air supply areas can provide air of different temperatures to patients and surgical personnel according to demand (for example, the high-temperature air supply area provides 26°C air for patients, and the low-temperature air supply area provides 22°C air for surgical personnel), meeting the different temperature requirements of patients and surgical personnel. This solves the problem that when the traditional operating room laminar flow ceiling is in use, the air supply temperature of the operating room only meets the requirements of the surgical team members but not the requirements of the surgical patients, causing the patients to suffer from hypothermia.

For example, "fixation" can mean fixed connection, detachable connection, or integration; it can mean mechanical connection or electrical connection; it can mean direct connection or indirect connection through an intermediate medium; it can mean internal communication between two elements or interaction between two elements, unless otherwise expressly specified. A person of ordinary skill in the art can understand the specific meanings of the above terms in this patent application based on the specific circumstances.
[0033] Example 1
[0034] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 As shown, an operating room partitioned different temperature air supply laminar flow ceiling includes a high temperature air supply area 100 and a low temperature air supply area 200, and the high temperature air supply area 100 and the low temperature air supply area 200 form a laminar flow ceiling box.
[0035] The laminar flow ceiling box includes four boxes 600, and a partition 300 is provided in the box 600. The partition 300 divides the laminar flow ceiling box into a high-temperature air supply area 100 and a low-temperature air supply area 200. The high-temperature air supply area 100 is arranged in the middle of the laminar flow ceiling box, and the low-temperature air supply area 200 is arranged on both sides of the laminar flow ceiling box; a fixed base 310 is provided in the laminar flow ceiling box, and the fixed base 310 is arranged at the connection of the four boxes 600.
[0036] An air inlet 400 and an air outlet surface 410 are provided on the high-temperature air supply area 100 and the low-temperature air supply area 200. A high-efficiency filter 500 is provided in the high-temperature air supply area 100 and the low-temperature air supply area 200 (the high-efficiency filter is mainly used to capture particulate dust and various suspended matter larger than 0.5 microns, and serves as the end filter of various filtering systems); the high-efficiency filter 500 is arranged above the air outlet surface 410, and a flow balancing layer is provided between the high-efficiency filter 500 and the air outlet surface 410. The flow balancing layer makes the air delivered from the high-temperature air supply area 100 and the low-temperature air supply area 200 more uniform.
[0037] Laminar flow ceilings are essential purification devices in modern operating rooms and serve as the final purification air supply terminal for clean operating rooms and laminar flow wards. They combine high-efficiency filtration, flow equalization, and airflow compensation. Although current purification systems are further subdivided into fresh air and recirculated air (fresh air refers to fresh air brought in from outside, which is typically cooler than the room temperature; recirculated air refers to air circulated within the room, which is typically the same temperature or slightly higher), since a typical laminar flow ceiling only has one space, the fresh air and recirculated air are mixed within the ceiling before being delivered to the operating room patients and surgical staff at the same temperature.
[0038] When the invention provides a laminar flow ceiling with zoned, differential temperature air supply in an operating room, fresh air enters from the air inlet 400 of the high-temperature air supply area 200, and circulating air enters from the air inlet 400 of the low-temperature air supply area 100. The high-temperature air supply area 100 and the low-temperature air supply area 200 are two areas that are not connected, so there is no mixing of fresh air and circulating air in the laminar flow box. After the fresh air and circulating air enter the equalizing layer from the high-efficiency filters 500 in the high-temperature air supply area 100 and the low-temperature air supply area 200 respectively, they are evenly delivered to the patient and staff areas, making both personnel feel comfortable and preventing overcooling or overheating.
[0039] In the present invention, because the high-temperature air supply area 100 and the low-temperature air supply area 200 are independent areas, not only is the mixing of fresh air and circulating air isolated, but also the components arranged in the high-temperature air supply area 100 and the low-temperature air supply area 200 cannot occupy the space of another area. When the width of the low-temperature air supply area 200 does not allow the high-efficiency filter 500 to be installed upright (horizontally), the high-efficiency filter 500 is installed on the inner side of the air inlet 400 in the low-temperature air supply area 200 in a side-mounted (vertically) manner. The side-mounted high-efficiency filter 500 not only meets the purification effect of the laminar ceiling, but also does not require changes to the structure of the low-temperature air supply area 200, and is suitable for use in situations where space is limited (such as ship operating rooms).
[0040] like Figure 4 、 Figure 5 As shown, in one design, the high-temperature air supply area 100 is 600mm wide and connected by PVC round pipes, supplying high-temperature fresh air to the indoor space (the operating room). The low-temperature air supply area 200 is connected by square pipes, supplying low-temperature circulating air to the indoor space (the operating room). The boxes 600 are connected by bolts, making assembly simple and quick. If the laminar flow ceiling is damaged, only the box 600 containing the damaged area needs to be replaced, without having to replace the entire laminar flow ceiling, reducing product costs.
[0041] Example 2
[0042] like Figure 5 、 Figure 6 As shown, in this embodiment, a fixed structure 610 is provided in the box body 600, and the fixed structure 610 includes a load-bearing plate 611, a first support frame 612, a second support frame 613, a fixing ring 614, a square tube 615, a first horizontal plate 616 and a second horizontal plate 617; the fixing ring 614 connects the first horizontal plate 616 and the second horizontal plate 617, the square tube 615 and the first support frame 612 are arranged on the load-bearing plate 611, the second support frame 613 is connected to the first support frame 612, and the second support frame 613 is connected to the first horizontal plate 616.
[0043] The fixing structure 610 is used to enhance the stability of the box 600 and adjacent boxes 600 connected by bolts. To enhance the bearing capacity of the fixing structure 610, the square tube 615 and the first support frame 612 can be welded to the load-bearing plate 611, which can be welded to the box 600. The second support frame 613 is plugged into the first cross plate 616, and the second support frame 613 can be welded to the first support frame 612. The fixing structure 610 can be made of stainless steel to ensure good hardness and rigidity.
[0044] Example 3
[0045] like Figure 5 As shown, in this embodiment, a zoned, differential temperature laminar flow ceiling for an operating room further includes a support plate 420, which is disposed below the air inlet 400 and connected to the inner wall of the housing 600. A high-efficiency filter 500 is secured to the support plate 420. The support plate 420 can be made of flat steel, which offers high strength and stability, capable of supporting the weight of the high-efficiency filter 500. The connection between the support plate 420 and the inner wall of the housing 600 effectively connects the four housings 600 in the high-temperature air supply area 100 into a single unit. The support plate 420, in conjunction with the bolts, further enhances the stability of the high-temperature air supply area 100. Furthermore, the support plate 420 ensures that air entering the air inlet 400 can only pass through the high-efficiency filter 500 before exiting the air outlet 410, thereby ensuring the quality of the air discharged from the air outlet 410.
[0046] Furthermore, when the high efficiency filter 500 in the low temperature air supply area 200 is installed in a normal manner, a support plate 420 is also installed in the low temperature air supply area 200 to fix the high efficiency filter 500.
[0047] Example 4
[0048] like Figure 2As shown, in this embodiment, during surgery, the doctor needs a sufficiently bright light source to assist in observing the surgical site. The patent of the present invention is provided with a center hole 311 on the fixed base 310, and a shadowless lamp is installed in the center hole 311. In order to provide a comfortable temperature for the patient, the high-temperature air supply area 100 is arranged directly above the patient, and the fixed base 310 is in the middle of the high-temperature air supply area 100, so the shadowless lamp is arranged in the center hole 311. At the same time, the wires that power the shadowless lamp can be led out from the center hole 311 to avoid the exposed wires affecting the appearance. In the present invention, the space is reasonably utilized to arrange the shadowless lamp, and there is no need to add other structures to install the lighting device, saving space costs and equipment costs.
[0049] Example 5
[0050] like Figure 1 As shown, in this embodiment, a connector 401 is provided on the air inlet 400, and the connector 401 is used to extend the air inlet 400. The air inlet 400 is provided on the side of the box body 600, and the connector 401 is connected to the side of the box body 600 by bolts. An airtight gasket is provided on the contact surface between the connector 401 and the side of the box body 600. The airtight gasket is made of rubber or silicone material and is used to enhance the airtightness of the connection between the connector 401 and the side of the box body 600. The connector 401 can be as follows Figure 1 The rectangular shape shown may also be a circular tube or a square shape. The connector 401 may be manufactured in a variety of different models to adapt to different vents (outlets for fresh air or circulating air), thereby enhancing the adaptability of the laminar flow ceiling.
[0051] Example 6
[0052] like Figure 8 As shown, in this embodiment, a bracket 210 is provided on the low-temperature air supply area 200. The cross-section of the bracket 210 is "U"-shaped, and a mounting hole is provided on the bracket 210. The bracket 210 is used to install the different-temperature air supply laminar ceiling.
[0053] The bracket 210 includes a long plate, a short plate and a connecting plate. The long plate, the short plate and the connecting plate form a "U" shape. The long plate is connected to the low-temperature air supply area 200 (welding can be used), and the mounting holes are set on the short plate and the connecting plate. Construction personnel can flexibly use bolts to connect the short plate or the connecting plate according to the on-site installation environment to fix the laminar ceiling.
[0054] Example 7
[0055] like Figure 2As shown, in this embodiment, the air outlet surface 410 is provided with a plurality of ventilation holes 411, which are evenly distributed on the air outlet surface 410. The air outlet surface 410 is detachably connected to the high-temperature air supply area 100 and the low-temperature air supply area 200 via screws. When installing the laminar flow ceiling, construction personnel can select an air outlet surface 410 with an appropriate number and size of ventilation holes 411 to connect to the high-temperature air supply area 100 and the low-temperature air supply area 200 based on factors such as the operating room area, operating room height, occupant density, and equipment power, to ensure the performance and effectiveness of the air supply system.
[0056] At the same time, the detachable design of the air outlet surface 410 also makes it convenient for maintenance personnel to repair the high-efficiency filter 500 when a fault occurs. There is no need to remove the entire laminar flow ceiling. Only the air outlet surface 410 needs to be removed to repair the high-efficiency filter 500, which saves maintenance personnel time.
[0057] Example 8
[0058] In this embodiment, the laminar flow ceiling with differential temperature air supply designed in this patent is primarily used in operating rooms, which place high demands on safety and air quality. Therefore, the high-temperature air supply area 100 and the low-temperature air supply area 200 are constructed of fireproof or antibacterial materials, such as metal plates or gypsum boards. Metal plates and gypsum boards are also strong and hard, withstanding prolonged friction and use without wear and deformation. Their smooth surfaces facilitate decorative treatments such as painting and spraying, thereby enhancing the laminar flow ceiling's aesthetic appeal.
[0059] The specific embodiments described above provide further detailed descriptions of the technical solutions, technical problems solved, and beneficial effects of the present invention. It should be noted that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
