During the outbreak of infectious diseases, medical staff need to take corresponding protective isolation measures to avoid infection. For the ophthalmology department and otorhinolaryngology department, the operation is carried out under a microscope/endoscope, the operation part of a patient and the nose and mouth of the patient are exposed to the air in an operation room, bacteria and virus droplets are dispersed in the air to generate aerosol, and the operation doctor, a nurse and the operation exposed part of the patient and the nose and mouth of the patient are exposed to an aerosol environment containing the bacteria and the virus except the surgical mask. Aerosols with bacteria or viruses at the exposed parts of the operation and at the mouth and nose of the patient without effective isolation measures from medical care during the operation are important mechanisms causing medical care infection. Although medical personnel can wear protective masks, floating aerosols cannot be effectively handled, and the delicate operation of the five sense organs is influenced by heavy protective measures.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a protection casing for ENT surgery prevention aerosol, this protection casing can keep apart the space between patient and the operation microscope in ENT surgery, prevents the propagation of aerosol, reduces medical personnel's infection risk.
The utility model provides a technical scheme that its technical problem adopted is:
a protective cover for aerosol prevention in ENT surgery comprises a transparent cover body, wherein the top edge of the transparent cover body can be matched with a surgical microscope in a sealing way; the surface of the transparent cover body is provided with an air inlet, an air outlet and a surgical instrument operation port; the air inlet is provided with an air inlet filtering membrane, the air outlet is used for connecting a negative pressure aspirator, and the operation port of the surgical instrument is provided with an air choke valve.
Further, the air inlet is positioned above the air outlet.
Furthermore, a micro fan is further arranged on the surface of the transparent cover body, and the micro fan supplies air into the transparent cover body.
Further, the intake filter membrane is of grade N99.
Further, the air outlet is provided with an air outlet filtering membrane.
Further, the outlet filtering membrane is of grade N99.
Further, the transparent cover body is made of flexible materials.
Furthermore, an annular vertical piece is arranged along the bottom edge of the transparent cover body and naturally sags, so that the bottom edge of the transparent cover body can be naturally attached to the periphery of a patient.
Furthermore, the hanging piece is a plastic rope loop.
Further, the surface of the transparent cover body is subjected to antifogging treatment.
The utility model has the advantages that:
first, this protection casing can keep apart the space between patient and the operation microscope in ENT surgery, prevents the propagation of aerosol, reduces medical personnel's infection risk.
And secondly, the miniature fan supplies air to the transparent cover body, the negative pressure suction unit draws air outwards, and air exposed to the field of operation is sucked out, filtered and subjected to harmless treatment in an air flow convection mode.
And thirdly, the air inlet and the air outlet are both provided with N99-level filter membranes, so that viruses are effectively filtered, and further propagation is prevented.
Fourthly, through the operation port of the surgical instrument with the air-blocking valve, the operation is convenient, and the air isolation effect is achieved.
And fifthly, the bottom edge of the transparent cover body is provided with an annular vertical piece which naturally droops, so that the bottom edge of the transparent cover body can naturally fit with the periphery of a patient, the sealing effect is improved, and the aerosol splashing risk is further reduced.
And sixthly, the surface of the transparent cover body is subjected to antifogging treatment, so that the sight of medical personnel is not influenced.
Drawings
The invention will be further described with reference to the following figures and examples:
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, the utility model provides a protective cover for aerosol prevention in ENT surgery, which comprises a transparent cover body 1, wherein the transparent cover body 1 is made of flexible material, such as medical plastic film; the top edge of the transparent cover body 1 can be in sealing fit with the operating microscope 2, and can adopt a common medical sealing connection mode, such as gluing, annular buckle sealing and the like; the surface of the transparent cover body 1 is provided with an air inlet 3, an air outlet 4 and a surgical instrument operation port 5; the present embodiment is provided with two air inlets, two air outlets and two operation ports for surgical instruments.
The air inlet 3 is positioned above the air outlet 4, the air inlet 3 is provided with an air inlet filtering membrane 6, the air outlet 4 is provided with an air outlet filtering membrane 8, the air outlet 4 is used for connecting a negative pressure aspirator, and the operation port 5 of the surgical instrument is provided with an air choke valve 7.
