Abstract
The utility model discloses a laryngeal mask airway, which comprises a cuff, an inflating tube, an indicating balloon arranged on the inflating tube, and a gas charging valve arranged in a free end port of the inflating tube, wherein the inflating tube is connected with the cuff; and the cuff is communicated with an oral and pharyngeal air tube. The utility model provides an easily positioned laryngeal mask airway to solve the problem that the conventional laryngeal mask airway is flexible in air tube and inconvenient to position. The laryngeal mask airway has the technical advantages that: the oral and pharyngeal air tube is combined with the traditional laryngeal mask airway; because the oral and pharyngeal air tube is harder and the laryngeal end is sealed with a laryngeal cavity, the laryngeal mask airway is easy to position.
Description
Technical field
This utility model relates to a kind of laryngeal mask, need promptly carry out the patient that artificial ventilation is supported when being applied to anesthesia in clinical or medicine abirritative patient and first aid and recovery, and is unobstructed to reach upper respiratory tract.
Background technology
The LMA laryngeal mask is the anaesthetist by Britain----Archie doctor Brain invention in nineteen eighty-three.Laryngeal mask mainly is made up of cover capsule, laryngeal mask intubate, indication sacculus, gas tube, machine end joint and charge valve, need promptly carry out the patient that artificial ventilation is supported when being applicable to anesthesia or medicine abirritative patient and first aid and recovery, to reach the unobstructed purpose of upper respiratory tract, compare with tracheal intubation, venturi stimulates little, respiratory tract mechanical obstruction is few, and patient is easier to accept: 1. the cardiovascular system reaction is less when inserting and extracting; 2. the less generation throat pain of postoperative; 3. need not to use throat and muscle relaxant just can insert; 4. simple to operate, easy, abecedarian just can slap through training for several times.
Oropharyngeal airway is one of emergency aid articles of Emergency Room indispensability, is the simplest, rapid, effective air flue ancillary method.Take rapidly allocation mouth Pharynx trachea accurately for critical patients such as dyspnea companion glossoptosis common in the emergency call salving work, to guarantee breathing unimpeded and gas exchange, thereby improve ventilation, stablize the state of an illness, earn a bare living, for the further diagnoses and treatment of critical patient strive opportunity.
Oropharyngeal airway hardness is stronger, and cavum laryngis is open, is mainly used in the processing of glossoptosis, can't connect artificial ventilation equipment.
But the pipe section of laryngeal mask is softer, and laryngeal mask part is big, usually occur in the use placing not in place, leak gas or insert situation such as difficulty, require to have certain degree of being skilled in technique and skill during use.Therefore, need a kind of laryngeal mask newly developed, overcome above-mentioned shortcoming.
The utility model content
Technical problem to be solved of the present utility model is, and is softer at existing laryngeal mask snorkel, is not easy to localized problem, and a kind of localized laryngeal mask that is easy to is provided.
This utility model solves the problems of the technologies described above by following technical proposal:
A kind of laryngeal mask comprises cover capsule, gas tube, is arranged at the indication sacculus on the gas tube and is arranged at the interior charge valve of gas tube free end port that gas tube is communicated with the cover capsule, and the cover capsule is communicated with an oropharyngeal airway.
In order to make the easier operation of laryngeal mask, can connect artificial ventilation equipment again, described oropharyngeal airway place is provided with catheter interface.
Technological merit of the present utility model is, oropharyngeal airway and conventional laryngeal mask are combined, because the pipeline of oropharyngeal airway is harder, throat end and cavum laryngis are airtight, therefore, are easy to positioning action.

5---catheter interface
The specific embodiment
As shown in Figure 1, a kind of laryngeal mask comprises cover capsule 1, gas tube 2, is arranged at the indication sacculus 3 on the gas tube 2 and is arranged at the interior charge valve (not shown) of gas tube 2 free end ports that gas tube 2 is communicated with cover capsule 1, and cover capsule 1 is communicated with an oropharyngeal airway 4.
In order to make the easier operation of laryngeal mask, can connect artificial ventilation equipment again, the free end of described oropharyngeal airway 4 is provided with catheter interface 5.
Of the present utility model oropharyngeal airway 4 and conventional laryngeal mask are combined, because the pipeline of oropharyngeal airway 4 is harder, throat end and cavum laryngis are airtight, therefore, are easy to positioning action.
Weak point is that its pipeline is hard partially, and the laryngeal mask part is littler than LMA laryngeal mask, just covers on throat, and is bigger to throat irritation, need be coated with on the surface during use to touch anesthetics or the topical anesthesia of row throat, also can use in general anesthesia.
Claims (2)
1. a laryngeal mask comprises cover capsule, gas tube, is arranged at the indication sacculus on the gas tube and is arranged at the interior charge valve of gas tube free end port, and gas tube is communicated with the cover capsule, it is characterized in that: the cover capsule is communicated with an oropharyngeal airway.
2. laryngeal mask according to claim 1 is characterized in that: described oropharyngeal airway place is provided with catheter interface.
