Abstract

The invention discloses a novel laryngeal mask. The novel laryngeal mask comprises an air bag, a breathing tube, a double-channel joint, an inflating tube, an indication air bag and a one-way valve, wherein an air inlet end of the breathing tube comprises a trachea channel and an esophagus drainage channel which are independent from each other; the trachea channel is divided into a trachea main channel and a trachea branch channel which are connected with each other; an epiglottis lifting table is arranged in front of the trachea main channel; and a wedge-shaped groove is formed in front of the epiglottis lifting table. The novel laryngeal mask is reasonable in design, meets clinical requirements and can be smoothly pressed in the throat of a patient; contents in the esophagus and the stomach of a patient can be drained; breathing of the patient in a surgery is guaranteed; using safety is improved; and tracheal intubation can be carried out through the laryngeal mask.

Description

A kind of new-type laryngeal mask

Technical field

The present invention relates to endotracheal intubation field, particularly relate to a kind of new-type laryngeal mask.

Background technology

In existing laryngeal mask patent, laryngeal mask comprises parallel air pipe passway, esophagus drainage channel, and linking arm, linking arm and air pipe passway, esophagus drainage channel are in vertical relation, namely laryngeal mask linking arm is positioned at below joint, and when after laryngeal mask human body, laryngeal mask fixed-wing is close to and is fixed on upper lip, during prolonged operations, the compressing due to fixed-wing easily causes patient's upper lip lesion ruptures.

CN101203261A discloses a kind of laryngeal mask airway devices, and it is provided with a baffle plate; After patient's brain, use gauze after a few circle, undertaken fastening by baffle plate; Or with rubber plaster, patient facial region's skin and baffle plate are adhesively fixed.Its weak point is this fastening means complex operation, connects built on the sand, and easily causes damage to the skin of face of patient or hair.

Although existing drain laryngeal mask is inserted conveniently, can not complete the exchange of tracheal intubation and laryngeal mask through laryngeal mask circulation of qi promoting cannula, intubatton type laryngeal mask price is higher can not take into account again the drainage inserted smoothly and to esophagus.

Laryngeal mask is not only to insert smooth and easy in clinical requirement, but also wants to carry out drain to esophagus and gastric content, and can complete tracheal intubation through laryngeal mask when needed.

Summary of the invention

The object of the invention is the technological deficiency for existing in prior art, and provide a kind of new-type laryngeal mask.

The technical scheme adopted for realizing object of the present invention is: a kind of new-type laryngeal mask, is characterized in that: comprise air bag, breather, two channel joint, gas tube, pilot balloon and check valve; The inlet end of described breather comprises two mutual independently air pipe passway and esophagus drainage channels; Described air pipe passway is divided into the trachea main channel and trachea subchannel that interconnect in the outlet side of described breather, described tracheal branches passage is positioned at side or the side-lower of described trachea main channel; The front of described trachea main channel is provided with epiglottis elevator platform, and the front of described epiglottis elevator platform is provided with wedge-shaped impression; The end lifting of described trachea main channel also walks around described epiglottis elevator platform in the direction that raises up; Described tracheal branches passage is communicated with described wedge-shaped impression.

Described air bag comprises the knapsack of cover capsule and curved-surface structure; Described esophagus drainage channel is provided with outlet in the end of described knapsack; Described outlet is provided with the arc-shaped sections adapted with the curved surface of described knapsack.

Further, described two channel joint comprises air pipe passway joint and esophagus drainage channel joint; Described air pipe passway joint is provided with a pair linking arm in the lateral symmetry of its radial direction, and the end of described linking arm is provided with the fixing band hook of T font.

Further, the external interface of described esophagus drainage channel joint tilts towards the direction away from described air pipe passway joint, and both form slanted angle.

The slanted angle of the external interface of described air pipe passway joint and the external interface of esophagus drainage channel joint is 30 ° ~ 60 °.

Preferably, described slanted angle is 45 °.

Preferably, the internal diameter cross section of the internal interface of described air pipe passway joint is oval.

Operation principle of the present invention is: in laryngeal mask, be provided with epiglottis elevator platform and wedge-shaped impression; Epiglottis elevator platform, for improving the height of epiglottis, can avoid epiglottis to block the venthole of trachea main channel effectively; Wedge-shaped impression can be used in storing human secretion, avoids secretions to block trachea; Apart from the above, air pipe passway divide into two the trachea main channels and trachea subchannel that interconnect in outlet side, even if after can ensureing that trachea main channel is blocked by epiglottis like this, tracheal branches passage can also play the effect of ventilation, ensure that the normal ventilation in operation, avoid the asphyxiant malpractice of patient.

Compared with prior art, the invention has the beneficial effects as follows: laryngeal mask is reasonable in design, meet clinical requirement, not only smoothly laryngeal mask can be pressed into patient's bottleneck throat, but also want to carry out drain to esophagus and gastric content, ensure that operation ventilation, improve safety in utilization, and the operation of tracheal intubation can be completed by laryngeal mask.
