Description
Technical field
A kind of laryngeal mask is the utility model is related to, more particularly to a kind of inflation-free laryngeal mask, belongs to medical instruments field.
Background technology
Quick respiration channel of establishing is one of rescue successful key of urgent patient.Trachea cannula be establish artificial airway,
Keep airway unobstructed, recover ventilation requisite measure, but exist technical operation requirement height, difficult intubation and be delayed intubation time,
The problem of causing anoxic to aggravate.
Laryngeal mask is applied in general anesthesia operation, establishes the effective means of pressure-relief vent.With people's grinding extensively to laryngeal mask
Study carefully, be extended to it in first aid rescue by the field of anaesthetizing merely.
Existing laryngeal mask includes inflatable laryngeal mask and inflation-free laryngeal mask.
Inflatable laryngeal mask is provided with supervisor and gas tube, is responsible for for conveying oxygen and for draining to patient, inflation
Manage for becoming big rear enclosed gas leakage gap to the airbag aeration for being arranged at laryngeal mask front end, air bag.When malleation is inflated, exist because of pressure
It is too high and cause gaseous distention, trigger the danger backflowed and inhaled by mistake；Because inflation laryngeal mask for a long time extruding pharyngeal cavity and caused by the pharyngeal damage of patient
Wound；Make standard inflation cover internal pressure because of hyperinflation and nitric oxide and dioxide dispersion performed the operation in the long period simultaneously in
It is too high, it is possible to causing pharyngeal mucosa ischemic lesions, tongue hyperemia and lingual nerve injury, and it is likely to increase postoperative pharyngalgia
With cracked generation, it is unfavorable for the treatment and recovery of patient's state of an illness.
Inflation-free laryngeal mask can effectively solve the problem that above mentioned problem existing for inflatable laryngeal mask.Existing inflation-free laryngeal mask bag
Include and be integrally formed formula laryngeal mask and assembly type laryngeal mask.The formula laryngeal mask of being integrally formed is integrated formed structure, and its anterior termination can not basis
Patient's throat situation is adjusted, incomplete so as to there is respiratory tract sealing, and oral secretion increase, easily displacement can not be effective
Isolate respiratory tract and alimentary canal, gaseous distention can be caused, the problems such as concurrently backflowing when serious or inhale by mistake, therefore limit it in clinic
In application.Assembly type laryngeal mask generally includes body, the expanding part of bottom of the pipe, and the front end of expanding part forms a slice shape,
Its leading edge is provided with a protruded stigma, and lower section extends to form extension edge in the end of body, in addition to one surround the week for being incorporated into expanding part
The soft supporter of ring-type enclosed, and a flexible gum cover with stickiness and tension force, expanding part and supporter are coated integral.
This assembly type laryngeal mask can be rapid and accurately with tracheae close to contraposition, can reduce the damage at patient contact position, avoid cover body
Turned down because touching larynx rear wall.But during practical clinical, it is not strong that the assembly type laryngeal mask still has sealing
Problem, in the case of respiratory tract sealing not exclusively, patient's gaseous distention will be caused, concurrently backflow or miss when serious and inhale symptom.

Side wall is fixedly connected with support set and outside gum cover.
As further improvement of the utility model, the lower end of the drainage tube is provided with circuitous configuration.
As further improvement of the utility model, the circuitous configuration is that tube wall is bent towards drainage tube major axes orientation is deviateed
Bending structure, or the contracted structure inwardly tightened for tube wall.
As further improvement of the utility model, it is provided with the inwall of drainage tube, along the bearing of trend of drainage tube
Some cross one another lines.
As further improvement of the utility model, the cross one another lines is closely coupled, is covered with drainage tube
Wall.
The beneficial effects of the utility model are as follows：
Inflation-free laryngeal mask of the present utility model with drainage, sets up in the tubular body of existing assembly type laryngeal mask
Drainage tube, drainage tube are arranged at cover body front end, after operating personnel's contraposition that laryngeal mask is close with tracheae, are corrected under drainage tube
Aligned with the esophagus of patient, when reflux occurs, reflux thing can be brought out through drainage tube；Circuitous configuration effectively prevent to backflowing
The erroneous judgement of situation, while prevent extraneous gas from entering stomach through esophagus by drainage tube.Lines design inside drainage tube makes anti-
Stream thing can be more swimmingly brought out.
