Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a fresh air purification unit for a clean operating room. Background Art

[0002] The operating room is a place for patients to undergo surgery and rescue, and is an important technical department of the hospital. The operating room should be connected to the surgical department, and should also be close to the blood bank, intensive care unit, anesthesia recovery room, etc. The four ways of surgical incision infection should be managed well, namely: the air in the operating room; the items required for the operation; the fingers of doctors and nurses and the skin of patients to prevent infection and ensure the success rate of the operation. It is required to have a reasonable design, complete equipment, and nurses' responsive and fast work, and high work efficiency. The operating room should have a set of strict and reasonable rules and regulations and aseptic operation specifications.

[0003] In operating rooms and some rooms that require sterility, purification fans are used for ventilation in order to purify the air. However, existing fresh air purification units often introduce the filtered airflow directly into the room during purification. This method may not disinfect the residual viruses directly without direct disinfection, and is inconvenient to disassemble and maintain. Based on this, we propose a fresh air purification unit for clean operating rooms. Utility Model Content

[0020] The working principle of the above technical solution is as follows: when in use, the user first installs the device at the bottom of the ceiling by installing the bolts 2, and connects the air ducts of the guide through the air inlet 5 and the air outlet 6 respectively. When fresh air purification is performed, the high-speed fan 22 is started to extract the air from the air outlet 6 and the inside of the box 1, and a negative pressure is formed inside the box 1. At this time, the airflow enters the inside of the box 1 through the guide of the air inlet 5, and is blown to the outside of the light conical disk 12 under the action of the guide. The light conical disk 12 is blown under the action of the turbine blades 13 contacting the airflow. The movement causes the turbine blades 13 to rotate and guide the airflow to the outside. At this time, the ultraviolet irradiation lamp 14 is always on and contacts the dispersed airflow, and the airflow is initially irradiated and sterilized. Then the airflow is filtered through multiple medical 95-grade air filters 17 plates and irradiated and sterilized by the ultraviolet disinfection lamp belt 18 on the opposite side. The double ultraviolet sterilization can perfectly kill viruses and bacteria, increasing safety. Finally, the airflow enters the use room through the air outlet 6 and the diversion of the air duct, with good overall killing efficiency and good killing effect.

[0021] In another embodiment, Figure 1-Figure 4 As shown, one end of the fastening spring 4 is in active contact with the inner side of the reinforcing mounting plate 3, and the other end of the fastening spring 4 is in active contact with the bolt head of the mounting bolt 2. The four reinforcing mounting plates 3 are evenly distributed on the outside of the box body 1 in a rectangular shape, and the side mounting plate 9 is located in the middle part of the reinforcing mounting plates 3.

[0022] The arrangement of the mounting bolts 2, the reinforcing mounting plate 3 and the side mounting plate 9 increases the convenience of installing the box 1. At the same time, the side stabilizing force can be increased through the side mounting plate 9, thereby increasing the firmness, facilitating installation and use, and providing a good overall use effect, thereby increasing the use effect.

[0023] In another embodiment, Figure 1 As shown, a sealing rubber strip is arranged on the inner side of the sealing cover plate 8 , and the sealing cover plate 8 is fixedly mounted on the outer side of the box body 1 by means of bolts, and a notch matched with the sealing cover plate 8 is provided on the front side of the box body 1 .

[0024] By setting the sealing cover 8, when the interior of the box body 1 needs maintenance, the bolts and the sealing cover 8 can be removed, and the medical 95-grade air filter 17 and cleaning and maintenance can be carried out inside the box body 1 through the groove of the box body 1, which increases the convenience and allows the operator to perform maintenance by simply disassembling the box body 1 through the escalator. The overall use effect is good, it is easy to clean and maintain, the use effect is good, and the work burden is reduced.

[0025] In another embodiment, Figure 3 and Figure 4 As shown, the turbine blades 13 are evenly distributed on the outer side of the lightweight conical disk 12 in a circumferential manner, and the direction of the lightweight conical disk 12 corresponds to the position of the air inlet 5 .

[0026] The turbine blades 13 can blow and guide the airflow outwards after coming into contact with the blowing airflow and under the action of the arc-shaped guide, the overall use effect is good, which is convenient for breaking up the airflow and making it evenly contact with the ultraviolet irradiation lamp 14, thereby improving the efficiency of disinfection and stabilizing the disinfection effect.

[0027] In another embodiment, Figure 3 and Figure 4 As shown, a flange ring is fixedly installed at the bottom of the inner circulation pipe 15 , the inner circulation pipe 15 is fixedly passed through the bottom of the box body 1 and extends to the inside of the box body 1 , and the top end of the inner circulation pipe 15 corresponds to the direction of the lightweight conical disk 12 .

[0028] The function of the internal circulation pipe 15 is that when it is necessary to filter the air flow inside the room, the connection of the air inlet 5 can be closed by the electric valve 19, and the connection of the internal circulation pipe 15 can be opened by removing the blocking block 21. At this time, the internal circulation pipe 15 is connected to the inside of the room through a pipeline, which is convenient for filtering and disinfecting the internal circulation and increases adaptability.

[0029] In another embodiment, Figure 3 and Figure 4 As shown, the slide rail 16 and the medical 95-grade air filter 17 are linearly and evenly distributed inside the box 1, and the ultraviolet disinfection light strip 18 is located on the opposite side of the slide rail 16 and the medical 95-grade air filter 17.

[0030] The uniform distribution of the slide rail 16, the medical 95-grade air filter 17 and the ultraviolet disinfection light strip 18 facilitates increasing the filtering and sterilizing effects on the air, stabilizes the operation, avoids slipping through the net, and improves efficiency.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
