[0019] Example 1 like Figure 1-3 As shown, a protective endoscope mask comprises a mask 1 with an airbag at the edge, and a protective sealing device 2. The airbag at the edge of the mask 1 makes the mask fit the face better and improves the airtightness. The mask 1 is provided with a nose-shaped protrusion facing the nose, so that the mask is more in line with the shape of the human face. The mask nose-shaped protrusion is provided with an oxygen pipe port 11 and an equipment port 12 connected to the oxygen supply pipe. The equipment port 12 is arranged at the lower side of the oxygen pipe port 11, corresponding to the mouth of the mouth. The oxygen pipe port 11 is provided with an air-sealing branch pipe 13 with a valve. The mask nose-shaped protrusion is provided with a one-way exhaust hole, and an activated carbon filter is arranged in the exhaust hole. The protective sealing device 2 includes a protective shell 21, a guide seal 22, a first seal 23, and a second seal 24. The protective shell 21 is a cylinder, which is installed on the equipment port by tightening the buckle. The protective shell 21 is located on the outer end of the mask and is provided with a guide seal 22, the inner end is provided with a first seal 23, and the middle is provided with a second seal 24. An air inlet 25 is provided on the protective shell between the first seal 23 and the second seal 24, and the air inlet 25 is connected to the air sealing branch pipe 13 hose. A one-way valve 26 is provided on the protective shell. The one-way valve 26 is located on the shell between the first seal and the second seal, and is located on the inner side of the mask. When in use, when the air pressure in the protective shell is too high, the one-way valve relieves the pressure and releases excess gas to the inner side of the mask to ensure that the polluted gas leaks out.

[0020] The guide seal 22 includes a shell with an inner cavity formed by the fixed connection of the left and right shells, a through hole is set in the middle of the shell, the shell is fixedly connected to the protective shell 21, and a guide seal ring is set in the inner cavity of the shell. The guide seal ring includes a silicone ring 221, a pair of snap-fitting pressure rings 222, and a conical seal ring 223. The pressure ring 222 is consistent with the inner diameter of the shell through hole. The pressure ring 222 is located between the silicone ring 221 and the conical seal ring 223, and the outer side is fixedly connected to the silicone ring 221, and the inner side is fixedly connected to the conical seal ring 223. The guide seal is set at the entry end of the equipment to ensure the flexibility of the equipment. The conical seal ring fits the equipment and has a good sealing effect. A cover is set on the guide seal to close the conical seal ring.

[0021] The first sealing member 23 is a cross valve conical sealing cap, the top of the cone is a cross-shaped surface, and a cross-shaped opening is provided on the cross-shaped surface to form a cross valve port. The cross valve port of the first sealing member faces outward, and a concave spherical surface 231 is provided at the center of the cross-shaped surface at the top of the cone of the first sealing member to assist in guiding the equipment to enter. The second sealing member 24 is a cross valve conical sealing cap, the top of the cone is a cross-shaped surface, and a cross-shaped opening is provided on the cross-shaped surface to form a cross valve port. The cross valve port of the second sealing member faces inward. The ratio of the spacing between the first seal 23 and the second seal 24 to the spacing between the second seal 24 and the guide seal 22 is 2:1. The larger space between the first seal and the second seal can be beneficial to the gas sealing effect. The four vertical surfaces of the cross-shaped surface of the first seal and the second seal are arc-shaped surfaces, which improves the sealing effect of the gas on the first and second seals.

[0022] When in use, the endoscope is inserted from the guide seal. The silicone ring of the guide seal can make the conical sealing ring move in the shell, thereby ensuring the operational flexibility of the endoscope. After the endoscope enters the protective shell from the guide seal, the second seal is inserted, and then the first seal is inserted to enter the inside of the mask. Since the first seal is a cross end face facing the endoscope, an inner concave spherical surface is provided on the cross end face to facilitate the passage of the endoscope. If necessary, a protective mouth can be connected to the inner end of the protective shell to facilitate the endoscope to enter the patient's mouth. When the endoscope needs to be pulled out, the air-sealing branch is opened, and oxygen enters the protective shell from the branch. When the endoscope is pulled out of the first seal, the first seal is naturally closed due to the cross-slit opening. At the same time, the gas in the protective shell exerts a certain pressure on the first seal, further pressing the cross-slit to improve the sealing effect. Similarly, when the endoscope leaves the second seal, as the gas continues to enter and the cross-slit of the second seal closes, the gas also exerts pressure on the second seal, thereby sealing the space between the first and second seals to improve the sealing performance. The guide seal is mainly used for the sealing of the overall protective shell, that is, to ensure that the pollution source does not expand when the endoscope is inserted into the first and second seals. The present invention cleverly utilizes oxygen for two-way sealing, which greatly ensures the protective effect during the withdrawal stage of the endoscope and prevents the threat of splashing of patient secretions to medical staff at any time.

[0023] Example 2 It also includes a gown with a mask opening, an annular groove on the mask along the outer edge of the mask, the annular groove is fixed with the mask opening of the gown, and the gown and the mask are used in combination to further prevent the spread of pathogens and confine the pathogens within the gown.

[0024] Example 3 The mask's flexible seal is a round strip of silicone material, which functions similarly to an airbag and facilitates the fit of the mask to the face.

[0025] Example 4 A nasal device opening is arranged on the vertical surface of the nose-shaped protrusion facing the nostrils, and a protective sealing device is arranged on the nasal device opening, so that the mask function can be expanded and applied to respiratory department.
