Background technique

The main route of transmission of some respiratory diseases is respiratory droplet transmission, mainly through the air. During the bronchoscopic examination of patients, medical staff will have close contact with patients, and patients will produce a large number of droplets and aerosols when they cough, which will pollute indoor equipment, air and related medical staff. In order to protect medical staff, such patients usually wear protective masks, which are connected to oxygen supply equipment to supply oxygen for patients to assist breathing. However, when performing a bronchoscopy on a patient, the bronchoscope needs to be inserted through the mask into the patient's mouth and nose for inspection. There are corresponding holes on the protective mask, which are usually blocked and opened during bronchoscopy to extend into the bronchi. The catheter of the bronchoscope needs to be adjusted during the inspection process, so the hole is slightly larger than the catheter of the bronchoscope, resulting in poor airtightness of the protective mask during the inspection process, and there is a risk of leakage and infection of medical staff .

Referring to FIGS. 1 to 5 , a bronchoscope protective mask includes a cover body 1 , a fixing belt 2 , an oxygen supply connector 3 and a bronchoscope connector 4 .

Wherein, the cover body 1 matches the shape of the patient's face and covers the patient's mouth and nose, thereby surrounding the patient's mouth and nose, preventing the gas breathed by the patient from being discharged to the outside to cause pollution. In one embodiment, the cover body 1 is transparent and made of silicone.

The two ends of the fixing belt 2 are connected to the cover body 1, and the fixing belt 2 can adopt an elastic band, and can also be provided with an elastic adjustment buckle. The fixing belt 2 is used to firmly fix the mask body 1 on the patient's head, so as to prevent the mask body 1 from detaching from the patient's face and causing leakage. It is a common practice in the field to use the fixing belt 2 to fix the mask, and its specific structure can refer to the conventional technology, so it will not be repeated here.

The oxygen supply connector 3 is fixed on the cover body 1, one end communicates with the inside of the cover body 1, and the other end is used to connect the oxygen supply equipment. It is inserted and fixed on the connecting head of the oxygen delivery tube, and the oxygen supply equipment is used to supply oxygen in the mask body 1 to assist the patient to breathe.

Wherein, the bronchoscope connecting head 4 is arranged on the cover body 1 , and a flexible connection part 5 is provided between it and the cover body 1 . The inner side of the flexible connection part 5 is fixedly connected to the bronchoscope connector 4, and the outer side of the flexible connection part 5 is fixedly connected to the cover body 1. Through the flexible connection part 5, the bronchoscope connector 4 can be connected to the cover body 1 Certain adjustment operations are performed to facilitate direction adjustment when the bronchoscopic catheter 6 is inserted into the patient's mouth and nose, thereby improving operational efficiency. The bronchoscope connector 4 includes a guide tube 41 and a plug 42 for blocking the guide tube 41. The guide tube 41 includes an outer tube section 411 outside the cover body 1 and extends into the cover body. 1, the inner pipe section 412 above the nose and mouth, the inner pipe section 412 communicates with the outer pipe section 411; the outer pipe section 411 is provided with an elastic sealing sheet 43, and the elastic sealing sheet 43 is provided with There is an opening 431 for inserting the bronchoscope catheter 6 , the size of the opening 431 is larger than the outer diameter of the bronchoscope catheter 6 , and the plug 42 detachably blocks the outer end of the outer tube section 411 . In normal times, the plug 42 seals the outer tube section 411 to ensure the airtightness inside the mask. When bronchoscopic examination is required, the plug 42 is removed, and the bronchoscope catheter 6 is inserted from the outer tube section 411 through the elastic sealing sheet The opening 431 of 43 protrudes from the inner tube section 412. Since the inner tube section 412 is located above the mouth and nose and is relatively close to the mouth and nose, the flexible connection part 5 is deformed by readjusting the bronchoscope connector 4, and the bronchoscope catheter 6 is guided into the patient. oral or nasal cavity for further testing. In one embodiment, the elastic sealing sheet 43 is in the shape of a sheet made of elastic rubber, which is similar to the film layer of a balloon and has good elasticity.

Preferably, in order to prevent the plug 42 from being lost after being removed, a connecting band 421 is provided between the plug 42 and the outer pipe section 411 .

Specifically, the plug 42 has a tapered slope 422. When the plug 42 blocks the guide pipe 41, the tapered slope 422 is inserted into the outer pipe section 411, and the tapered slope 422 of the plug 42 , so that the more the plug 42 is plugged in, the better the sealing effect will be.

Wherein, the flexible connecting part 5 protrudes from the cover body 1 and is in the shape of a truncated cone. It is soft, and its truncated cone shape allows it to be deformed by pressing down on one side, thereby adjusting the direction of the guide tube 41, and then adjusting the direction of the bronchial tube. The action of stretching into the patient's mouth and nose of mirror catheter 6. The flexible connection part 5 is integrally connected with the cover body 1, and both are made of transparent silica gel. The flexible connection part 5 is relatively thin, so that it can be deformed to a certain extent.

The seat body 44 is directly fixed on the flexible connection part 5, and the two are integrally connected. The seat body 44 is provided with a threaded hole, and the screwing part 45 is directly threaded on the seat body 44, and a sealing ring is also provided between the two. , to ensure the sealing effect after screwing. After being screwed together, the inner pipe section 412 is inserted into the inner side of the cover body 1 above the mouth and nose.

Wherein, the inner tube section 412 is provided with a first bent section 4121 bent towards the patient's nostril and/or a second bent section 4122 bent towards the patient's mouth. The bending of the first bending section 4121 makes its opening 431 face the patient's nostril, so that the bronchoscopic catheter 6 can be directly aligned and protruded into the nasal cavity after passing out of the guide tube 41 . In the same way, the bending of the second bending section 4122 makes its opening 431 face the mouth of the patient, so that the bronchoscopic catheter 6 can be directly aligned and stretched out of the oral cavity after passing through the guide tube 41. When the catheter 6 is inserted into the oral cavity or nasal cavity, the bronchoscopic catheter 6 is selected to be extended into the first bending section 4121 or the second bending section 4122 .

In one embodiment, the opening 431 is circular and has a diameter smaller than the outer diameter of the bronchoscope catheter 6 , so as to ensure the sealing effect of the bronchoscope catheter 6 inserted into the opening 431 .

In one embodiment, the opening 431 is "one" or S-shaped, and the length of the opening 431 is smaller than the outer diameter of the bronchoscope catheter 6, so as to ensure the sealing effect of the bronchoscope catheter 6 inserted into the opening 431 .

In addition, the bronchoscopic protective mask is also provided with a sputum suction tube connector whose structure is similar to that of the bronchoscope connector 4 and will not be repeated here.
