The operating room should be connected to the surgical department, and should also be close to the blood bank, ICU, 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 surgery; 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.

[0003] As an important place in medical institutions, the operating room has strict requirements on air quality. Ventilation devices are installed inside the operating room for air circulation and purification. However, during use, the existing ventilation devices have a large structure and volume, which is not easy to install and fix. In addition, the purification device is a certain distance away from the operating room. It is difficult to ensure the absolute purification effect during the air transportation process. The end of the device does not have a secondary purification effect, which is insufficient in terms of purification effect. Therefore, it is of great significance to develop an operating room gas purification ventilation device with a small structure and volume, easy installation, and good purification effect.

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] like Figures 1 to 5 As shown, a ventilation device for gas purification in an operating room includes a ventilation cylinder 2, a ventilation pipe 5 is fixedly connected to the right side of the ventilation cylinder 2, an upper end cover 1 is threadedly connected to the upper side of the ventilation cylinder 2, a plurality of fixed support components 4 are arranged on the annular surface of the ventilation cylinder 2, a baffle plate 3 is arranged at the bottom of the ventilation cylinder 2, a ventilation mesh cover 6 is fixedly arranged on the lower side of the baffle plate 3, and a purification component 7 is arranged inside the ventilation cylinder 2. This design solves the problems that the original ventilation device has a large structure and is not easy to install and fix, and the purification device is a certain distance away from the operating room, it is difficult to ensure an absolute purification effect during the air transportation process, the end of the device does not have a secondary purification effect, and there are deficiencies in the purification effect.

[0026] The purification assembly 7 includes a support base plate 78, an ultraviolet lamp 71, a primary filter cartridge 72, a medium filter cartridge 73, a high efficiency filter cartridge 74 and a HEPA filter paper net cylinder 75. The support base plate 78 is an annular structure fixedly arranged on the lower side of the inner part of the ventilation tube 2. A support net cylinder 76 is fixedly arranged on the upper side of the support base plate 78. The outer side of the support net cylinder 76 is respectively sleeved with a HEPA filter paper net cylinder 75, a high efficiency filter cartridge 74, a medium efficiency filter cartridge 73 and a primary filter cartridge 72 from the inside to the outside, and there is a gap between the primary filter cartridge 72 and the inner wall of the ventilation tube 2. An ultraviolet lamp 71 is arranged on the upper side of the support net cylinder 76, and the ultraviolet lamp 71 is fixedly connected to the upper end cover 1. An axial flow fan 77 is installed on the lower side of the support net cylinder 76. The purification assembly 7 of this design can remove particulate matter, microorganisms and other pollutants in the air by combining the technologies of multi-layer filtration, ultraviolet disinfection and axial flow fan 77. The primary filter cartridge 72 is used to remove larger particles, such as dust and hair, to provide pretreatment for subsequent filtration. The medium-sized particles are further filtered through the medium-efficiency filter cartridge 73 to protect the high-efficiency filter from being blocked prematurely. The high-efficiency filter cartridge 74 can capture smaller particles, including many bacteria and some viruses. The HEPA filter paper net cylinder 75 is the most efficient filter layer, which can purify and filter the air again to filter out most bacteria and viruses. The ultraviolet lamp 71 is widely used in the disinfection of air and surfaces, and can effectively kill microorganisms that may still exist after passing through the filter cartridge, such as bacteria, viruses and molds. The function of the axial flow fan 77 is to generate airflow, suck air into the ventilation tube 2, and blow it out after purification.

[0027] The primary filter cartridge 72 is a non-woven filter with a larger pore size and better air permeability, so that air can pass smoothly while intercepting larger pollutants. The medium-efficiency filter cartridge 73 is air filter paper, which has a smaller pore size and can capture smaller particles than the non-woven filter. It is used to further filter out medium-sized particles, such as pollen, mold spores, etc. The high-efficiency filter cartridge 74 is a honeycomb activated carbon filter. The honeycomb activated carbon filter combines the adsorption capacity of activated carbon and the interception capacity of high-efficiency filter materials. It can adsorb harmful gases and odors in the air, such as volatile organic compounds. The honeycomb structure provides a larger surface area, increases the contact area with the air, and thus improves the adsorption efficiency.

[0028] A protective mesh plate 79 is provided inside the ventilation duct 2, and the protective mesh plate 79 is located at the lower side of the axial flow fan 77. The protective mesh plate 79 plays a protective role and can shield and protect the axial flow fan 77.

[0029] The fixed support assembly 4 includes a connecting plate 41, a suspension rod 42, a bolt 43 and an ear plate 44. The ear plate 44 is fixed on the annular surface of the ventilator 2. The ear plate 44 is penetrated by a suspension rod 42, and the suspension rod 42 is fixedly connected to the ear plate 44 by two groups of bolts 43. A connecting plate 41 with a mounting hole is welded on the top of the suspension rod 42. The fixed support assembly 4 realizes the stable installation of the ventilation device in the operating room through the combined structure of the ear plate 44, the suspension rod 42, the bolt 43 and the connecting plate 41. The structure is reasonable, the installation is convenient, and the ventilation device can withstand various external forces and weights, ensuring the safety and stability of the ventilation device during operation.

[0030] A handle 11 is fixedly provided on the upper side of the upper end cover 1. The handle 11 provides a convenient and comfortable gripping point for the operator, making it easier to open and close the upper end cover 1, facilitating the installation of the upper end cover 1, and facilitating the installation and removal of the internal purification component 7. A layer of sealing rubber pad 12 is laid inside the upper end cover 1. The sealing rubber pad 12 enhances the sealing between the upper end cover 1 and the ventilator 2, ensuring the sealing of the connection. By enhancing the sealing performance, the sealing rubber pad 12 helps to improve the purification efficiency of the ventilation device, ensuring that the purified air can be fully transported to the interior of the operating room without being leaked into the external environment.

[0031] The ventilation cylinder 2 and the ventilation pipe 5 of the utility model can be made of electrolytic steel plates, which meets the construction requirements of the operating room.
