Abstract
The utility model relates to the technical field of medical appliances, in particular to a laryngeal mask airway. The laryngeal mask airway comprises a cuff, a laryngeal mask airway cannula and an inflating pipe, wherein the cuff is connected with one end of the laryngeal mask airway cannula; one end of the inflating pipe is provided with an inflating valve; and the other end of the laryngeal mask airway cannula is provided with a left branch pipe and a right branch pipe. The laryngeal mask airway is characterized in that a cavity communicated with the inflating pipe is arranged on the inner wall of the laryngeal mask airway cannula; one end of the cavity is connected with the cuff; the other end of the cavity is provided with a cavity opening; the other end of the inflating pipe is connected with the cavity opening; the cross section of the cavity on the inner wall of the laryngeal mask airway cannula is elliptic; the cavity opening length is 1-2 cm; and the cavity opening is formed in the position where is 3 cm away from the left branch pipe and the right branch pipe. The laryngeal mask airway provided by the utility model has simple structure, convenience for use, reasonable design, and capabilities of effectively using the structure of the laryngeal mask airway cannula and ensuring that examination and treatment are carried out successfully and a patient can have enough aeration under narcosis.
Description
Technical field
This utility model relates to a kind of laryngeal mask, and it belongs to medical instruments field.
Background technology
At present, fiberoptic bronchoscopy is a kind of means of diagnosis respiratory disease, adopts and under intravenous anesthesia, inserts earlier the standard laryngeal mask; The method of checking through laryngeal mask insertion branchofiberoscope then is generalizable clinically, and its structure of an existing laryngeal mask normally end of gas tube is drawn from the cover capsule separately, and the other end of gas tube connects charge valve; Laryngeal mask is in use drawn separately with intubate because elongated gas tube is independent, often may twine, tie a knot or fracture occurs because of dental articulation; Influence inflation effect; If gas tube occurs breaking because of above-mentioned situation, secretions can get into air flue, malpractice can occur.
The utility model content
This utility model provides the laryngeal mask of a kind of laryngeal mask intubate and gas tube integrative-structure to the deficiency of prior art.
The technical scheme that this utility model solves the problems of the technologies described above is following: a kind of laryngeal mask; Comprise cover capsule, laryngeal mask intubate and gas tube, said cover capsule is connected with said laryngeal mask intubate one end, and an end of said gas tube is provided with charge valve; The other end in said laryngeal mask intubate is provided with left and right branched pipe; Be characterized in that said laryngeal mask intubate inwall is provided with the cavity that is communicated with gas tube, said cavity one end is connected with the cover capsule; The said cavity other end is provided with cavity hatch, and the other end of said gas tube is connected with said cavity hatch.The length of said cavity hatch is 1-2cm.
The beneficial effect of this utility model is: this utility model simplicity of design; Convenient and practical, when adopting the laryngeal mask execution fiberoptic bronchoscopy of this utility model, because of it is disposable plasticity laryngeal mask; The dissect physiology structure that meets the human body throat; Being wholely set of said laryngeal mask intubate and gas tube, the complicated structure of conventional laryngeal mask has been avoided tiny inflation pipe fracture before having improved; Not only can guarantee carrying out smoothly of fiberoptic bronchoscopy and treatment, and can guarantee that the patient has enough ventilations under narcotism; Cavity hatch length is that the phenomenon that is extruded or bends can not appear in gas tube when guaranteeing that gas tube is connected with cavity hatch, guarantees normal ventilation.。
On the basis of technique scheme, this utility model can also be done following improvement.
Further, the cavity section of said laryngeal mask intubate inwall is oval.
Adopt the beneficial effect of above-mentioned further scheme to be, guaranteeing has certain thickness and laryngeal mask intubate to isolate around the cavity, can not influence laryngeal mask intubate global shape, and it is reasonable in design, does not influence to insert trachea inspection mirror.
Further, said cavity hatch place is apart from laryngeal mask intubate upper end 3cm.
Adopt the beneficial effect of above-mentioned further scheme to be, do not influence being connected of left and right branched pipe and laryngeal mask intubate, realize being wholely set of laryngeal mask intubate and gas tube.

Fig. 2 is the structural representation of Fig. 1 along A-A.
In Fig. 1 and Fig. 2,1, the cover capsule; 2, laryngeal mask intubate; 3, charge valve; 4, gas tube; 5, part arm on the left side; 6, cavity; 7, cavity hatch; 8, part arm on the right side.
The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of this utility model are described, institute gives an actual example and only is used to explain this utility model, is not the scope that is used to limit this utility model.
As depicted in figs. 1 and 2, a kind of laryngeal mask comprises cover capsule 1, laryngeal mask intubate 2 and gas tube 4; Said cover capsule 1 is connected with said laryngeal mask intubate 2 one ends; One end of said gas tube 4 is provided with charge valve 3, is provided with at the other end of said laryngeal mask intubate 2 to part arm 5 on the left side and part arm 8 on the right side, is characterized in; Said laryngeal mask intubate 2 inwalls are provided with the cavity 6 that is communicated with gas tube; Said cavity 6 one ends are connected with cover capsule 1, and said cavity 6 other ends are provided with cavity hatch 7, and the other end of said gas tube 4 is connected with said cavity hatch 7; The cavity section of said laryngeal mask intubate 2 inwalls is oval; The length of said cavity hatch 7 is 1cm; Said cavity hatch 7 places are apart from laryngeal mask intubate 2 upper end 3cm.
The above is merely the preferred embodiment of this utility model, and is in order to restriction this utility model, not all within the spirit and principle of this utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of this utility model.
