Abstract
A drainage type laryngeal mask comprises a mask vesicle and a main duct. A drainage cavity is arranged in the main duct. A drainage hole on the drainage cavity is installed on the tail end portion of the small end of the mask vesicle. The section shape of the tail end of the small end of the mask vesicle is ellipse. According to the drainage type laryngeal mask, the opening of the small end of the drainage type laryngeal mask is ellipse-shaped and more matched with the structural shape of a human esophagus, and therefore the esophagus is easy to seal. The drainage type laryngeal mask avoids that air enters into the esophagus and aggravates stomach reflux when an air passage duct is ventilated.
Description
Technical field
This utility model relates to be inputted medium in the human body or is passed to apparatus on the human body, relates to specifically a kind of trachea intubate.
Background technology
Laryngeal mask be a kind of be applied to that surgery anesthesia or critical patient rescue or other assisted respiartion set up the medical apparatus and instruments commonly used of artificial gas passage for the patient, basic structure has the cover capsule, airway and the gas tube of inflating for covering capsule, wherein, the conduction type laryngeal mask also can carry out drain to the esophageal regurgitation material except artificial gas passage is provided, its similar is in common laryngeal mask, just increased a drainage lumens parallel with airway, the drainage lumens end places in the cover capsule and the conduction hole of drainage lumens is located at the small end of covering capsule, the small end that covers in use capsule can stop up airtight esophageal orifice, and the conduction hole by the drainage lumens end will instead flow thing and stomach carries out drain.But there is following defective in present this conduction type laryngeal mask: the cross sectional shape of the small end cross sectional shape of cover capsule and the conduction hole of drainage lumens is circle, the small end cross sectional shape of cover capsule and the esophagus planform of human body are not exclusively identical, the cross sectional shape of esophagus is flat elliptic, such cover capsule can be hindered when inserting, and can not the complete closed esophagus, can cause airway tube when ventilation portion gas to enter into esophagus, stomach is counter flows in aggravation.The conduction hole cross section of drainage lumens is circular, and when stomach tube was inserted into conduction hole the esophageal regurgitation material is carried out drain, stomach tube and circular conduction hole can be fitted fully, causes airtightly, is not easy to drain.
The utility model content
The purpose of this utility model provides a kind of conduction type laryngeal mask, and its use is more convenient, reduces the damage to the patient, and the cover capsule can the complete closed esophagus, and portion gas enters into esophagus when avoiding ventilate because of airway, aggravates that stomach is counter to flow.
To achieve these goals, technical solution of the present utility model is: a kind of conduction type laryngeal mask, comprise cover capsule and supervisor, and be provided with drainage lumens in the supervisor, conduction hole on the drainage lumens is arranged at the terminal part of the small end of cover capsule, and the cross sectional shape of the small end end of described cover capsule is oval.
This utility model conduction type laryngeal mask, wherein, the cross sectional shape of described conduction hole is oval.
After adopting such scheme, the opening of this utility model conduction type laryngeal mask small end be oval, and is more identical with the planform of human body esophagus, is easy to airtight esophagus, and gas enters esophagus and aggravates that stomach is counter to flow when having avoided the airway tube ventilation.
In addition, the conduction hole cross sectional shape is oval, during drain between slotted eye meeting and the stomach tube two ends leave the gap to play decompressing effect, be convenient to drain.
Description of drawings
Fig. 1 is the structure chart of this utility model conduction type laryngeal mask;
Fig. 2 is the structure chart of the cover capsule of this utility model conduction type laryngeal mask.
Specify this utility model conduction type laryngeal mask below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, this utility model conduction type laryngeal mask comprises cover capsule 1 and supervisor 2, drainage lumens 3 is located in the supervisor 2 and the end of drainage lumens 3 stretches out in the small end 11 that supervisor 2 places cover capsule 1, the conduction hole 31 of drainage lumens 3 is arranged at the terminal part of small end 11, the cross sectional shape of small end 11 ends is oval, and the cross sectional shape of conduction hole 31 is oval.
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.
Claims (2)
