Modified model endoscopy anaesthetic maskTechnical field
The invention belongs to area of medical devices, relate to a kind of modified model endoscopy anaesthetic mask.
Background technology
At present, the anaesthetic mask commonly used within the hospital is both provided with insertion hole, oral cavity and/or nasal cavity inserts hole, oral cavityInsertion hole is mainly used in gastroscope and enters from the oral cavity of patient, and nasal cavity insertion hole can be used not only for bronchoscope and enters from the nasal cavity of patientEnter, and can be used for laryngopharyngeal mirror and ultra-fine gastroscope and enter from the nasal cavity of patient.Bronchoscope, laryngopharyngeal mirror, ultra-fine gastroscope are allIt is expensive precision instrument, owing to the angle of inclination of the nose rising zone of existing anaesthetic mask immobilizes, and props upTracheascope or laryngopharyngeal mirror or ultra-fine gastroscope can bend to bend low through patient's nasal cavity after slowly inserting in the way of mirror, thisKind of situation is easy for the epidermis causing bronchoscope or laryngopharyngeal mirror or ultra-fine gastroscope and is inserted the hole in hole along scratch by nasal cavity, fromAnd affect bronchoscope, laryngopharyngeal mirror, the normal service life of ultra-fine gastroscope.Further, since the nose type size of each patient is notIdentical, and the size of the nose rising zone of existing anaesthetic mask and angle of inclination are all changeless, so easilyNasal cavity is occurred to insert the problem that hole is the most corresponding with the naris position of patient.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of modified model endoscopy anaesthetic mask, its nasal regionFlexible and location can be carried out according to the nose situation of patient, thus avoid scratch bronchoscope or laryngopharyngeal mirror or ultra-fineThe epidermis of gastroscope, it has novel structure, flexible adjustment, design is more humane, practicality is higher feature.
In order to achieve the above object, the present invention takes following concrete technical measures: modified model endoscopy anaesthetic mask, it is made up of cover plate, elastic foundation ring, annular inflatable bag, four location gear pieces, it is characterised in that
The bottom sides of cover plate is along being provided with a circle elasticity foundation ring, and the bottom of this elasticity foundation ring is fastened with an annular inflatable bag,Being provided with the air inlet pipe of a band valve inside on elastic foundation ring, this air inlet pipe is connected with annular inflatable bag；
Wherein, cover plate includes proparea and back zone, and the proparea of cover plate is as correspondence district, oral cavity, and the back zone of cover plate is corresponding as nasal cavityDistrict；
Being provided with one a diameter of 3～the circular groove of 4cm in the middle part of the proparea of cover plate, this circular groove inner hub location is offeredHaving connecting hole, the surrounding at connecting hole is provided with 4 ~ 10 air-vents, is provided with the most convex in the middle part of the bottom surface of round plastic filmThe core bar gone out, round plastic film is by realizing the purpose in embedding circular groove in this core bar Snap joint hole；
The left and right sides in cover plate proparea is respectively arranged with the air chamber of a protuberance, and this air chamber maintains static, and the two air chamber is arrangedIn the left and right sides of circular groove, the outer incline Middle face of each air chamber is provided with a butt tube, this butt tube energy and gas transmissionOne pipe end of pipe realizes socket；
Offering a D-shaped hollow hole in the middle part of the back zone of cover plate, the edge of this D-shaped hollow hole is fastened with a circle elastic adhesive tape, shouldThe interior edge of elastic adhesive tape is fastenedly connected with the bottom sides edge of nose type case, and the leading flank of nose type case offers two circles in left and rightNasal cavity inserts hole, and left and right two alar part of nose type case trailing flank is each provided with two toothed positioning strips, is positioned at the band of front sideThe size of the positioning strip of tooth be more than in the size of toothed positioning strip of rear side；
The left and right sides on surface, cover plate back zone is fastened with a group bar respectively, and this two groups bar is arranged at the left and right of D-shaped hollow holeBoth sides, two group bars are all made up of long other bar and short other bar, and the other bar of every root length other bar short with every all corresponding can snap in oneLocation gear piece, each location gear piece is all convexly curved structure, and the bottom inverse bending of each location gear piece becomes level angle,Location gear piece realizes snapping in the purpose of other bar by this bottom being bent into level angle；
The intrados of each location gear piece is provided with taper tooth bar, and the intrados of each location gear piece can be with position by taper tooth barIn about nose type case trailing flank, the toothed positioning strip on two alar parts realizes occlusion.
Owing to elastic adhesive tape quality is soft and has elasticity, so the nose type case being connected with elastic adhesive tape also can realize spiritLive and regulate height and the purpose of gradient, thus can carry out the height to nose type case according to the nose feature that each patient is actualSpend and gradient regulates neatly and positions with the realization that is engaged of toothed positioning strip eventually through location gear piece.
The present invention can not only make the circular nasal cavity insertion hole on nose type case corresponding with the nostril of patient, and when a gasPipe mirror or laryngopharyngeal mirror or ultra-fine gastroscope from the nasal cavity of patient to bend low into the bending formed after slowly inserting in the way of mirrorState is not result in that epidermis is inserted the hole in hole along scratch by circular nasal cavity.
The beneficial effects of the present invention is, it has novel structure, flexible adjustment, design is more humane, practicality is higherFeature.
With embodiment, the present invention is illustrated further below in conjunction with the accompanying drawings.
