Description

Double cavity type oropharyngeal airway

Technical field

The utility model relates to a kind of medical instruments, and in particular to a kind of double cavity type oropharyngeal airway.

Background technique

Oropharyngeal airway is mainly used for patient clouded in mind after going into a coma, falls after preventing the root of the tongue, blocks air flue, keep exhaling It is unobstructed to inhale road；As bite-block, refined confinement tracheas suppressed conduit is avoided；Convenient for oral care, oropharynx merocrine secretion is also helped Object is sucked out.

Existing oropharyngeal airway, structure mostly as shown in Fig. 2, include the edge of a wing, a ventilation pipe on the edge of a wing, Ventilation pipe includes straight tube and the curve bend that connect with straight tube, and after setting pipe success, straight tube is proximal end, close to population, as tooth Pad part, curve bend is pharyngeal distally, to protrude into, and radian matches with oropharynx radian.The oropharyngeal airway of this structure is deposited In following defect: first, a ventilation pipe is only arranged, intake and exhaust is by this root ventilation pipe, and then influence oxygen The uptake of gas needs the oxygen of high flow capacity that could improve blood oxygen, causes the waste of oxygen resource, while not having on oropharyngeal airway There is a setting fixation, patient do not vomit independently, coughs, when can be under the abnormal conditions such as sneeze, easily causes the de- of ventilation pipe It falls, and then causes malpractice；Second, the material of ventilation pipe is really up to the mark, is mostly plastics system for the ease of being inserted into ventilation pipe Product easily cause Accessory injury, also easily deform in high-temperature condition, cavity is made to narrow, unfavorable ventilation.

Utility model content

In view of the deficienciess of the prior art, the utility model provides a kind of double cavity type oropharyngeal airway, this snorkel will It is separated into a small, big two-tube mode into and out of tracheae, patient is improved to the uptake of oxygen, prevents oxygen resource Waste, while also setting up the long band of fixation for the connection that can cooperate and fixing short strip, falling off for pipeline is prevented, malpractice is avoided Generation.

In order to achieve the above object, the technical solution that the utility model is taken:

Double cavity type oropharyngeal airway, including the edge of a wing, the edge of a wing is equipped with an oxygen inlet pipe, an oropharynx exhaust pipe, described The diameter of oropharynx exhaust pipe is bigger than the diameter of the oxygen inlet pipe, and the oropharynx exhaust pipe, oxygen inlet pipe include as bite-block Partial straight tube, the curved pipe to match with oropharynx radian, and the oropharynx exhaust pipe and the oxygen inlet pipe link together, Contiuum type double cavity structure is formed, the two sides on the edge of a wing are respectively equipped with a fixed long band, fix short strip, and the fixed long band, Fixed short strip is equipped with can mutually matched fixed device.

As optimal technical scheme, in order to guarantee that snorkel is non-toxic to humans, and reduces and the pair of human body oropharynx is damaged Hurt degree, the oropharynx exhaust pipe, oxygen inlet pipe are made of medical silica-gel.

As optimal technical scheme, for the ease of being fixedly connected between the long band of fixation and fixed short strip, and guarantee connection It is firm, falling off for pipeline is further prevented, the generation of malpractice is avoided, fixed long take offers several button holes, The fixed short strip is equipped with can buckle identical with button hole mating connection and quantity.

Compared with prior art, the utility model has the advantages that

1, this oropharyngeal airway, which is equipped with, to be provided separately into and out of tracheae in a small, big two-tube mode, changes existing one The structure of root ventilation pipe improves patient to the uptake of oxygen, prevents the waste of oxygen resource；Setting can cooperate simultaneously The long band of the fixation of connection and fixed short strip, effectively prevent falling off for oropharyngeal airway, avoid the generation of malpractice.

2, oropharynx exhaust pipe, oxygen inlet pipe are on the one hand to guarantee that snorkel is nontoxic to the human body made of medical silica-gel It is harmless, on the other hand reduce the Accessory injury degree to human body oropharynx.

3, fixed long band with fixed short strip by button hole, snap fit attachment, convenient between fixed long band and fixed short strip Be fixedly connected, and guarantee stable connection, further prevent falling off for pipeline, avoid the generation of malpractice.

Detailed description of the invention

The utility model is described in further detail in the following with reference to the drawings and specific embodiments.

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the structural schematic diagram of existing oropharyngeal airway；

Drawing reference numeral: 1, the edge of a wing, 2, oxygen inlet pipe, 3, oropharynx exhaust pipe, 4, fixed long band, 5, fixed short strip, 6, button hole, 7, it buckles.

Specific embodiment

A kind of specific embodiment of the utility model, double cavity type oropharyngeal airway, including the edge of a wing 1 are proposed as shown in Figure 1, it is described The edge of a wing 1 is equipped with an oxygen inlet pipe 2, an oropharynx exhaust pipe 3, and the oxygen inlet pipe 2 connects high pressure oxygen delivery pipe, keeps oxygen straight Up to pharyngeal tracheae, the oropharynx exhaust pipe 3 excludes lung and exhales, and the diameter of the oropharynx exhaust pipe 3 is than the oxygen inlet pipe 2 Diameter is big, and the oropharynx exhaust pipe 3, oxygen inlet pipe 2 include straight tube as bite block portion, the arc that matches with oropharynx radian Shape pipe, and the oropharynx exhaust pipe 3 and the oxygen inlet pipe 2 link together, form Contiuum type double cavity structure, the edge of a wing 1 Two sides be respectively equipped with a fixed long band 4, fixed short strip 5, and the long band 4 of the fixation, fixed short strip 5 are equipped with and can cooperate Fixation device.

The oropharynx exhaust pipe 3, oxygen inlet pipe 2 are made of medical silica-gel, and medical silica-gel has good biology Compatibility, it is nonirritant to tissue, non-toxic, few without allergic reaction, body rejection, have good physical and chemical special Property, with body fluid and tissue contact process in be able to maintain its it is original elasticity and pliability, guarantee oropharynx exhaust pipe 3, oxygen into Pipe 2 is non-toxic to humans, and reduces the Accessory injury degree to human body oropharynx.

Several button holes 6 are offered on the long band 4 of fixation, the fixed short strip 5, which is equipped with to cooperate with button hole 6, to be connected It connects and 5 button holes 6 and 5 buckles 7 is arranged in the identical buckle 7 of quantity, the present embodiment, buckle 7 convenient for connection and connects with button hole 6 It connects firm, consequently facilitating being fixedly connected between fixed long band 4 and fixed short strip 5, and guarantees stable connection, further prevent mouth Pharynx trachea falls off, and avoids the generation of malpractice.

When the utility model is used: oropharynx exhaust pipe 3, oxygen inlet pipe 2 curved portion along lingual surface buckle into it is pharyngeal after, solid Fixed length band 4 merges around neck and fixed short strip 5, is consolidated oropharyngeal airway by the button hole 6 and buckle 7 for the connection that cooperates It is fixed；Oxygen inlet pipe 2 is connected into oxygen supply device, completes operation.

Certainly, only the utility model preferred embodiment is described in detail in conjunction with attached drawing above, not The scope of the utility model is limited with this, it is all according to equivalence changes made by the principles of the present invention, construction and structure, It should all be covered by the protection scope of the utility model.
