Abstract
The utility model discloses a mask bag of a laryngeal mask airway. The mask bag comprises a drainage tube outlet, a mask bag body, a ventilation tube outlet and a laryngeal mask airway intubation tube inlet, and is made of medical silicon rubber. By virtue of the design that a drainage tube passes through the interior of the mask bag, the airflow resistance of a patient can be decreased, and attraction of esophageal regurgitation substances and gastric contents cannot be affected.
Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of two-tube laryngeal mask cover capsule.
Background technology
A kind of artificial respiration road that laryngeal mask (Laryngeal Mask airway, LMA) Shi You Britain anaesthetist Brain developed according to the throat structure of dissecting people in nineteen eighty-three.By laryngeal mask intubate, cover capsule, gas tube three parts, formed.Airway is similar to common endotracheal tube.Both can autonomous respiration by laryngeal mask patient, can implement positive airway pressure again, be a kind of a kind of tracheal intubation that maintains respiratory tract ventilation between face shield and tracheal intubation.
The instant Tube Drain type of two-tube laryngeal mask laryngeal mask, this kind of laryngeal mask can carry out drain to esophageal reflux material, its basic structure is similar to standard laryngeal mask, just there is a drainage tube parallel with breather, this drainage tube is by cover capsule and be opened on the tip of covering capsule, tip can be blocked in patient's introitus oesophagi in use, thereby can attract esophageal reflux thing and gastric content by most advanced and sophisticated opening.
The drainage tube of two-tube laryngeal mask is for passing through an exposed intubate on cover capsule surface in the market, while ventilating to patient, exposed drainage tube may cause that patient's gas-flow resistance strengthens, simultaneously, the air-flow of patient respiratory can produce pressure to drainage tube, causes drainage tube to flatten impact and attracts in time esophageal reflux thing and gastric content.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of laryngeal mask cover capsule, this laryngeal mask cover capsule makes drainage tube pass through from cover capsule the inside, thereby has avoided patient's gas-flow resistance that two-tube laryngeal mask drainage tube is exposed brought in the market and impact to attract in time esophageal reflux thing and gastric content problem.
This utility model is that to solve the problems of the technologies described above the technical scheme of employing as follows:
A laryngeal mask cover capsule, this cover capsule adopts medical grade silicon rubber to make, and tip design has drainage tube outlet, and the other end is designed with the laryngeal mask intubate entrance of (comprising drainage tube), is designed with the outlet of vented cannula near the cover capsule recess of laryngeal mask intubate porch.Laryngeal mask intubate bonds by medical glue and cover capsule.
Further, described laryngeal mask cover capsule adopts hollow design, drainage tube can be from cover capsule the inside by until the drainage tube at cover capsule tip export.
The laryngeal mask cover capsule of said structure, the design owing to having adopted drainage tube to pass through from cover capsule the inside, can reduce patient's gas-flow resistance, meanwhile, can not affect and attract esophageal reflux thing and gastric content.
Accompanying drawing explanation
Fig. 1 is a kind of laryngeal mask cover of this utility model capsule schematic diagram.
In figure: 1: drainage tube outlet
2: cover capsule
3: breather outlet
4: laryngeal mask intubate entrance
The specific embodiment
Fig. 1 has provided a kind of laryngeal mask cover capsule, comprises drainage tube outlet 1, cover capsule 2, breather outlet 3, laryngeal mask intubate entrance 4.This utility model, by the hollow design of cover capsule 2, makes drainage tube pass through until breather outlet 3 from cover capsule 2 the insides.Whole laryngeal mask cover capsule is made by medical grade silicon rubber.
During assembling, laryngeal mask intubate (comprising drainage tube) is inserted to drainage tube outlet 1 from laryngeal mask intubate entrance 4 through vacancy in cover capsule 2, now, airway outlet exports 3 places at breather, and drainage tube outlet exports 1 place at drainage tube.Laryngeal mask intubate and cover capsule bond by medical glue.
During use, laryngeal mask is depressed into lower pharyngeal cavity position straight till feel to have characteristic resistance (prompting arrives Upper esophageal sphincter) after head direction, can starts patient to carry out airway management.
Claims (2)
1. a laryngeal mask cover capsule, comprises drainage tube outlet, cover capsule, breather outlet, laryngeal mask intubate entrance, and cover capsule is hollow design.
2. laryngeal mask cover capsule according to claim 1, is characterized in that: drainage tube by until drainage tube exports, can reduce patient's gas-flow resistance from cover capsule the inside, meanwhile, can not affect and attract esophageal reflux thing and gastric content.
