Abstract

The utility model discloses a novel side-hole type airway device, which comprises a vent pipe body and a rear-wing port. The length of the vent pipe body is 20 cm. The vent pipe body comprises ridges, ring racks and porous films. The ridge is cylindrical. The diameter of the ridge is 2 mm and the length of the ridge is 5 mm. The texture of the ridge is relatively hard and elastic. The vent pipe body is formed by the orderly connection of 40 above structures and each of the structures is formed by a ridge, a ring rack and a porous film. The axis of the vent pipe body is bent and the drift angle of the axis is 30 degrees. The surface of the vent pipe body is smooth and the front section of the vent pipe body is a conical blind end formed by the extension of the porous film. The rear end of the vent pipe body extends to form the rear-wing port. The front part of the vent pipe body can be inserted into an esophagus. The ventilation performance can be maximally ensured by the plurality of side holes on the vent pipe body. The vent pipe body can be inserted into the esophagus via the nose or via the mouth of the patient. The rear-wing port is hard and difficult to bite. The patient is comfortable when the vent pipe body is placed inside the nose. Compared with the prior art, the device has the advantages of reliable effect, convenient operation, less danger and fewer complications.

Description

New side pass airway device

Technical field

This utility model relates to medical medical instruments field, is specifically related to a kind of new side pass airway device that uses clinically.

Background technology

In anesthesia with rescue in critical patient's the process, as the anesthesia of adiposis patient and the treatment of patient with brain trauma, glossoptosis can cause that upper respiratory tract blocks or suffocates, if untimely processing will cause anoxia and carbon dioxide accumulation.Often use oropharynx or nasopharynx airway clinically and keep respiratory passage unblocked, this also is one of basic skill of carrying out effective ventilation.The application of oropharyngeal airway is comparatively extensive, but it exists patient to tolerate poor shortcoming; The nasopharynx airway is littler than oropharyngeal airway to the zest of bottleneck throat, and clear-headed, semiconsciousness and light anaesthesia patient Geng Yi tolerance are particularly suitable for gnathospasma, lead the patient of arthrodesis and facial area damage down.At present, the front end of nasopharynx of Ying Yonging or oropharyngeal airway has only a hole clinically, the depth position of determining front aperture when inserting is relatively more difficult sometimes, in addition, the leading portion of nasopharynx airway also easy deformation when pressurized, the degree of mobility that these all can influence respiratory tract causes the holder lower jaw often inevitable.

The utility model content

The purpose of this utility model is to remove glossoptosis better, keeps respiratory passage unblocked, is the provide convenience new side pass airway device of a kind of clinical use of designing of clinical practice.

This utility model is that the technical measures that its technical problem of solution is taked are:

New side pass airway device comprises breather main body, rear wing port two parts; The breather principal length is 20cm, and it comprises spine, ring stand and pore membrane, and spine is cylindrical, diameter 2mm, and long is 5mm, quality is harder and flexible; Wide 1～the 1.5mm of ring stand, thick 0.5～1mm, interior diameter 6mm, quality is hard, and ring stand closely is connected with spine, and keep the ring stand inner and outer wall all level and smooth, fill the thick thin film of 0.5～1mm between ring stand, quality is pliable and tough, and all there is hole front and side, mainly be positioned at preceding 1/2 section of airway main body, diameter 2～3mm.

Above-mentioned new side pass airway device, it is characterized in that the breather main body is to be connected and composed in an orderly manner by 40 said structures, the bending of breather main body axis, the axis drift angle is 30 °, its smooth surface, and leading portion is a cecum, tapered, extended to form by pore membrane, the rear end extends to the rear wing port, comprises hole, thick 1.5～the 2mm of rear wing port, long 1～1.5mm, quality is hard, and it is the hole of 6mm, rear wing that respectively there is a diameter both sides, wherein a side roof part is a domatic, be beneficial to from then on that the hole attracts, the breather body shaft is good to toughness, puts pipe easily; On the cross section, strengthened the effect of breather main body tolerance extruding; Esophagus can be inserted in the front portion of breather main body, and its a plurality of side openings can guarantee venting capability to greatest extent; The taper cecum of breather main body and thin external diameter are also convenient to be inserted, little to mucosa injury; Can select per nasal or per os to insert approach, hard anti-the stinging of rear wing port, it is also more comfortable to put into the nostril.

That this utility model compared with prior art has is reliable for effect, easy to use, dangerous little, advantage such as complication is few.

The specific embodiment

New side pass airway device comprises breather main body 1, rear wing port 2 two parts; The breather principal length is 20cm, and it comprises spine 1-1, ring stand 1-2 and pore membrane 1-3, and spine 1-1 is cylindrical, diameter 2mm, and long is 5mm, quality is harder and flexible; Wide 1～the 1.5mm of ring stand 1-2, thick 0.5～1mm, interior diameter 6mm, quality is hard, and ring stand 1-2 closely is connected with spine 1-1, and keep ring stand 1-2 inner and outer wall all level and smooth, fill the thick thin film of 0.5～1mm between ring stand 1-2, quality is pliable and tough, and all there is hole front and side, mainly be positioned at preceding 1/2 section of airway main body, diameter 2～3mm; Breather main body 1 is to be connected and composed in an orderly manner by 40 said structures, breather main body 1 axis bending, the axis drift angle is 30 °, its smooth surface, leading portion is cecum, and is tapered, and 1-3 extends to form by pore membrane, the rear end extends to rear wing port 2, comprise hole 2-1, rear wing 2-1, rear wing port 2 thick 1.5～2mm, long 1～1.5mm, quality is hard, the hole 2-1 that it is 6mm that respectively there is a diameter both sides, wherein a side roof part is a domatic, being beneficial to from then on, the hole attracts, breather main body 1 axial toughness is good, puts pipe easily; On the cross section, strengthened the effect of breather main body 1 tolerance extruding; Esophagus can be inserted in the front portion of breather main body 1, and its a plurality of side openings can guarantee venting capability to greatest extent; The taper cecum of breather main body 1 and thin external diameter are also convenient to be inserted, little to mucosa injury; Can select per nasal or per os to insert approach, hard anti-the stinging of rear wing port, it is also more comfortable to put into the nostril.

During clinical concrete operations, select glossoptosis patient's a side nostril, spray local anaesthetics and drip an ephedrine in the nostril, lubricated new side pass airway device is inserted the nostril, and insert along inferior nasal meatus, the about 13～15cm of the degree of depth or directly insert esophagus, disappearing and breathe unobstructed with the sound of snoring is standard.If select the per os approach, then open patient's oral cavity, new side pass airway device is inserted, should provoke root of the tongue portion in case of necessity.

More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection of the present utility model.
