Embodiment 1

[0024] In this example, if Figure 1-2 As shown, this embodiment provides an anesthesia mask suitable for inspection tubes of various specifications, including a mask body 1, an oxygen inhalation tube 2 arranged on the mask body 1, and an inspection tube installed on the mask body 1. Check channel 3.

[0025] In this embodiment, by connecting the inspection channel 3 with the mask body 1, when the inspection channel 3 is not inserted into the inspection tube, the mask body 1 does not leak and has a sealing function; its upper end is provided with a sealing cap 31, which is not inserted. When inspecting the tube, the sealing cap 31 covers the inspection channel 1, so that the mask body 1 is in a sealed state.

[0026] In this embodiment, by designing an elastic opening 32 at the lower end of the inspection channel 3, the large-diameter sections of inspection tubes of various specifications or reduced-diameter inspection tubes also have smooth and sealing functions when inserte...

Embodiment 2

[0034] Such as image 3 As shown, in order to prevent the deterioration of the elastic performance when the coarse inspection tube enters the sealing elastic body 33 and is squeezed as a whole, the upper and lower walls (33-3, 33-4) can be provided with grooves, The upper and lower ends of the inner wall surface 33-2 are made of elastic body.

Embodiment 3

[0036] Such as Figure 4 As shown, in order to make the sealing elastic body 33 more elastic and reduce frictional resistance when in contact with the inspection tube, the shape of the inner wall surface 33-2 can be designed as a sawtooth structure.

Abstract

The invention relates to an anesthetic face mask suitable for inspection tubes of various specifications, comprising a face mask body, an oxygen inhaling tube arranged on the face mask body, and an inspection channel arranged on the face mask body for inserting the inspection tube; the anesthetic face mask comprises a face mask body, an oxygen inhaling tube arranged on the face mask body and an inspection channel arranged on the face mask body for inserting the inspection tube. The inspection channel is connected with the face mask body, the top end is provided with a sealing cap, the lower part of the sealing cap is provided with an opening, and a sealing elastic body is arranged in the opening; a locate ring is arranged on that upper part of the sealing elastomer. The invention has the following beneficial effects: 1, as the sealing elastomer is arranged in the inspection channel, the aperture of the sealing elastomer can be automatically opened or contracted under the external forceof the inspection pipe wall, so that the sealing ring elastomer is closely attached to the inspection pipe to ensure that the face mask does not leak air; 2, since that upper part of the seal elastomer is provided with a positioning re matched with the sealing cap, the upper end part of the opening in the inspection channel is not deformed, the cap can be buckled, and the installation cavity of the sealing elastomer can be formed together with the opening to protect the sealing elastomer from being completely squeezed and deformed in the opening.

Description

technical field [0001] The invention relates to a medical anesthesia tool, in particular to an anesthesia mask suitable for inspection tubes of various specifications. Background technique [0002] At present, clinically, the anesthesia mask used for general anesthesia insertion of the patient is generally provided with an oxygen inhalation port and an inspection channel on the mask body, and the lower end of the mask body is provided with a ring-shaped airtight air bag. When there are inspection tubes with different diameters, or when surgical instruments such as gastric intubation tubes are involved in emergency gastric lavage, the inspection tube has a variable diameter section, and there is a difference in the aperture of the inspection channel and the inspection tube. If there is a gap or close contact, the seal is not tight or the friction force is too large. At this time, the oxygen in the mask will leak from the gap, resulting in poor oxygen supply pressure in the ma...
