Abstract

Disclosed is a multi-cavity laryngeal mask. The multi-cavity laryngeal mask comprises a mask bag and an air way catheter. The air way catheter comprises a ventilation cavity, an esophagus drainage cavity and an air inflation cavity, and further comprises a sputum suction cavity or a liquid suction cavity and a decompression cavity. All the cavities are mutually parallel and are integrally formed in the air way catheter. Due to the adoption of the scheme of the multi-cavity laryngeal mask, because the air way catheter comprises the ventilation cavity, the esophagus drainage cavity and the air inflation cavity, and further comprises the sputum suction cavity or the liquid suction cavity and the decompression cavity, and all the cavities are integrally formed in the air way catheter, when secretions or sputum in the oral cavity of a patient needs suctioning out in the using process of the multi-cavity laryngeal mask, tubes do not need additionally inserting, and the multi-cavity laryngeal mask is more convenient to operate and reduces extra damage to the patient.

Description

The multi-cavity laryngeal mask
Technical field
This utility model relates to a kind of medical apparatus and instruments, relate to specifically a kind of be applied to that surgery anesthesia or critical patient rescue or other assisted respiartion set up the laryngeal mask of artificial airway's passage for the patient.
Background technology
Intubating laryngeal mask airway is Brain in the nineteen eighty-three invention and at first advocates use a kind of and adopt the airway that mode is ventilated outside the glottis.In order to improve the clinical application effect of intubating laryngeal mask airway, have three types intubating laryngeal mask airway at present: first kind is the standard type intubating laryngeal mask airway, it also is at present clinical intubating laryngeal mask airway the most commonly used, basic structure has cover capsule, airway and is the gas tube of cover capsule inflation, be mainly used in keeping the respiratory tract function, can not carry out drainage procedure; Second kind is the special-purpose intubating laryngeal mask airway of guidance tracheal intubation; The third is the conduction type laryngeal mask snorkel, is used for the esophageal regurgitation material is carried out drain, i.e. so-called two-chamber larynx cover.Though two-chamber larynx cover can carry out drain to the esophageal regurgitation material, but still need to insert in addition conduit to siphon away anti-stream thing or secretions or the sputum of oral cavity or bottleneck throat in operation or before the tube drawing of operation back sometimes, and can carry out smoothly when instead flowing thing or secretions or sputum for guaranteeing to inhale, also need insert other conduit and be reduced pressure in the throat.
The utility model content
The purpose of this utility model provides a kind of multi-cavity laryngeal mask, and its use is more convenient, and reduces in the use damage to the patient.
In order to achieve the above object, technical solution of the present utility model is: a kind of multi-cavity laryngeal mask, comprise cover capsule and airway tube, airway tube comprises venting cavity, esophagus drainage lumens, inflatable chamber, described airway tube also comprises inhales expectorant or imbibition chamber and relief chamber, and above-mentioned each cavity is parallel to each other, is shaped in the airway tube or is bonded to one mutually.
After adopting such scheme, this utility model multi-cavity laryngeal mask since its airway tube except comprising venting cavity, esophagus drainage lumens, inflatable chamber, also comprise and inhale expectorant or imbibition chamber and relief chamber, and each cavity is shaped in the airway tube, therefore in the use when secretions in needing the suction patient's mouth or sputum, need not other intubate, more convenient operation and minimizing are to patient's additional injuries.
Description of drawings
Fig. 1 is the structural representation of airway tube in this utility model multi-cavity laryngeal mask.
The specific embodiment
This utility model multi-cavity laryngeal mask comprises cover capsule and airway tube, the structure of airway tube as shown in Figure 1, comprise venting cavity 1, esophagus drainage lumens 2, inflatable chamber 3, inhale expectorant or imbibition chamber 4 and relief chamber 5, above-mentioned each cavity is parallel to each other, is shaped in the airway tube or is bonded to one mutually.
During use, the multi-cavity laryngeal mask is positioned over the throat of human body by the oral cavity, for the inflation of cover capsule, cover capsule and throat are fitted by inflatable chamber 3, then by venting cavity 1 air feed, by drainage lumens 2 drains, when needs are inhaled expectorant or imbibition, can will instead flow thing or secretions or sputum sucking-off from inhaling expectorant or imbibition chamber 4 then earlier by relief chamber 5 decompressions, need not to insert in addition conduit, reduce the damage to patient.
The above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from this utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
