Abstract
The utility model relates to an oxygen-inhaling nasal mask for a bronchoscope, which comprises a nasal mask body (1), an air inlet pipe (2), an air-supply hole (3) and a silica gel cushion (4), wherein the nasal mask body (1) takes the shape of a hollow double-layer semiellipse , two 3/4 round holes (5) are formed at the entrance of human nasal cavity in the middle below the nasal mask body (1), the air-supply hole (3) is formed on the inner side of the nasal mask body (1) along the round holes (5), the air inlet pipe (2) is connected to the lower section of the external surface of the nasal mask body, and the silica gel cushion (4) is positioned to the part which surrounds the inner side of the nasal mask body (1) and presses against human body. The nasal mask body (1) is made of polyvinyl chloride. The utility model can solve the problems of using safety and comfort of the bronchoscopy in the prior art.
Description
Technical field
This utility model belongs to person's windpipe mirror instrument field, particularly relates to a kind of tracheascope nose mask for breathing oxygen.
Background technology
Interventional therapy under fiberoptic bronchoscopy and the guiding thereof is the important means of respiratory system disease diagnosis and treatment, and the bronchoscope shank is generally by patient nostril turnover patient airway during routine operation.Because the object of being checked suffers from underlying diseases more, the perhaps anxiety in the operating process, anoxia to a certain degree can appear in the person under inspection in checking process.For avoiding this phenomenon, common way is to adopt common nose conduit oxygen supply, but the drawback of this way is: the nose conduit that, stretches into nasal cavity has occupied limited nasal cavity space, has hindered bronchoscopic operation to a certain extent; Two, when adopting bigger oxygen flow oxygen supply, the nose conduit that stretches into nasal cavity can stimulate nasal mucosa, makes the person under inspection produce discomfort.This situation has greatly hindered safety, cosily patient has been carried out the purpose of fiberoptic bronchoscopy.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of tracheascope nose mask for breathing oxygen, the problem of safety, comfortableness when using to solve prior art mesobronchus mirror.
The technical scheme that its technical problem that solves this utility model adopts is: provide this utility model to relate to a kind of tracheascope nose mask for breathing oxygen, comprise nose cup bodies, air inlet pipe, air vent and silicagel pad, described nose cup bodies is double-deck hollow half elliptic, thereunder central, there are two 3/4 circular holes the position that is positioned at people's nasal cavity inlet, described air vent is positioned at nose cup bodies along the circular hole inboard, described air inlet pipe is connected main body outer surface hypomere, and described silicagel pad is affixed on human body parts around being positioned at the nose cup bodies inboard.
Described nose cup bodies material is a polrvinyl chloride.
Beneficial effect
Advantage of the present utility model is that on the one hand, the air vent design of pressing close to nasal cavity had both guaranteed certain density oxygen supply, the unlikely again nasal cavity discomfort that causes that the high speed oxygen air-flow causes; On the other hand, circular air vent design need not occupy limited nasal cavity space, even also can carry out oxygen supply when tracheascope approaching side nasal cavity, thereby helps improving the safety and the comfortableness of bronchoscope operation.
Description of drawings
Fig. 1 is this utility model front view.
Fig. 2 is a circular hole of the present utility model place backsight partial enlarged drawing.
Wherein: 1-nose cup bodies, 2-air inlet pipe, 3-air vent, 4-silicagel pad, 5-circular hole.
The specific embodiment
Below in conjunction with specific embodiment, further set forth this utility model.Should be understood that these embodiment only to be used to this utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications this utility model after the content of having read this utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figures 1 and 2, the nose mask for breathing oxygen that this utility model provides is a material with polrvinyl chloride and silica gel, is made up of nose cup bodies 1, air inlet pipe 2, air vent 3 and silicagel pad 4.Wherein, nose cup bodies 1 is double-deck hollow half elliptic, and selecting polrvinyl chloride for use is material, to common oxygen absorption mask is similar but size is slightly little, and long 7cm, wide 5cm, high 3cm (can be made into different model during actual fabrication) to be fit to different shapes of face.The double-deck spacing of nose cup is 1mm.In nose cup bodies 1 bottom center, for people's nasal cavity entry position, 3/4 circular hole, 5, two pitchs of holes that the bilayer of main body is 1cm at these two diameters of formation of turning back are 0.5cm.Air vent 3 is the opening along circular hole 5 inner side main body internal layers, and bore dia is 0.5mm.Air inlet pipe 2 is positioned at main body outer surface hypomere, by hose connection oxygen supply pipeline.Around nose cup bodies 1, be affixed on the silicagel pad 4 that human body parts is thick 1mm.
During use, select the suitable types nose cup to be buckled in its nose, be fixed in nose, connect oxygen supply pipeline and can begin oxygen supply by elastic band according to person under inspection's shape of face.Branchofiberoscope can free in and out nasal cavity by nose cup below circular hole.
Claims (2)
1. tracheascope nose mask for breathing oxygen, comprise nose cup bodies (1), air inlet pipe (2), air vent (3) and silicagel pad (4), it is characterized in that: described nose cup bodies (1) is double-deck hollow half elliptic, thereunder central, there are two 3/4 circular holes (5) position that is positioned at people's nasal cavity inlet, described air vent (3) is positioned at nose cup bodies (1) along circular hole (5) inboard, described air inlet pipe (2) is connected main body outer surface hypomere, and described silicagel pad (4) is positioned at the inboard human body parts that is affixed on of nose cup bodies (1) on every side.
2. a kind of tracheascope nose mask for breathing oxygen according to claim 1 is characterized in that: described nose cup bodies (1) material is a polrvinyl chloride.
