A kind of Universal telescopic laryngeal maskTechnical field
This utility model relates to a kind of medical instruments, is specifically related to a kind of Universal telescopic laryngeal mask.
Background technology
At present, laryngeal mask is that the mid-80 is succeeded in developing and for clinical, introduce the domestic nineties.At present the use of laryngeal mask made great progress, be widely used in patient with general anesthesia, the patient of emergency department, ICU and each section office's first aid and recovery, the difficult airway patient, and also range of application is more and more wider.
Laryngeal mask has many advantages: (1) uses simple, can set up rapidly the artificial airway; (2) be placed to the power height, unbred medical personnel's success rate is 87%, total success rate 99.81%; (3) ventilation is reliable; (4) avoid the damage of throat and tunica mucosa tracheae; (5) stimulation is little, and cardiovascular response is little; (6) can be used for first aid.
But all laryngeal masks have a shortcoming at present, and that is exactly that the laryngeal mask cover is shifted because of the variation of incidence position easily, and its reason mainly is: laryngeal mask length is fixed, and the cover direction is fixed.And along with the change of incidence position, the distance between front tooth and glottis changes, and the right direction of front tooth and glottis also can change.During for example right overhead by neutral position left avertence, right avertence or layback, the distance between front tooth and glottis increases, and laryngeal mask is subjected to tractive to be shifted easily and leaks gas, and jeopardizes patient safety.
The utility model content
The technical problem that this utility model solves is to provide a kind of Universal telescopic laryngeal mask, thereby solves the problem in the above-mentioned background technology.
The technical problem that this utility model solves realizes by the following technical solutions:
A kind of Universal telescopic laryngeal mask comprises cover and breather, and described cover and described breather integrally combine, and it is characterized in that, described breather comprises two sections, and wherein one section is the level and smooth stationary pipes of tube wall, and another section is the telescoping tube of wave-like for tube wall.
In this utility model, described breather be combined with cover a section adopts stationary pipes or telescoping tube all can.
In this utility model, can select as required whether to arrange gas tube, for example: cover be solid silica gel then gas tube need be set; And if cover is the hollow gasbag type, the gas tube that links to each other with cover then is set, in order to inflation in the cover air bag or bleed, be used for regulating cover size and intracapsular pressure, make cover and patient throat fit and air tight.
As a kind of improvement, the coupling part of described stationary pipes and described telescoping tube arranges a circle caulking gum packing ring.
The characteristics of this utility model maximum are exactly that breather with laryngeal mask partly changes one section stationary pipes and one section telescoping tube that tube wall is wave-like that tube wall is level and smooth into, wherein telescoping tube can be realized stretching, and when neck location changes right overhead, such as head left avertence, right avertence, anteflexion, layback, the distance of front tooth and glottis also changes, this moment, corresponding with it elongation and shortening can occur in telescoping tube, thereby made the position of laryngeal mask cover not be vulnerable to the impact of incidence position change.And a circle caulking gum packing ring is set in the coupling part of described stationary pipes and described telescoping tube, increased sealing, therefore telescoping tube can rotate freely by 360 degree, thereby the spinning force that produces when better adapting to incidence change in location (for example a left avertence, right avertence) is on the impact of laryngeal mask cover position.
Because the universal and telescopic characteristic of telescoping tube, the breather part is relatively soft, difficulty may appear inserting in inserting the process of laryngeal mask, for handled easily, use a kind of tube core that adapts with breather, tube core can be rigid plastics or the metal of the fixedly radian of the matched not plasticity of breather internal diameter, also can be can crooked moulding rigid plastics or metal; When inserting tube core is inserted in the breather, conveniently inserts, insert laryngeal mask and fixing after, extract tube core and get final product.
Owing to adopted above technical scheme, the utlity model has following beneficial effect:
This utility model is simple in structure, can make laryngeal mask better adapt to the incidence change in location, has improved medical and nursing quality.

Fig. 3 is the structural representation of the third embodiment of this utility model.
The specific embodiment
For technological means, creation characteristic that this utility model is realized, reach purpose and effect is easy to understand, below in conjunction with specific embodiment, further set forth this utility model.
Referring to Fig. 1, the first embodiment.A kind of Universal telescopic laryngeal mask, comprisecover 1 andbreather 2, in the present embodiment, also comprisegas tube 3, describedcover 1 integrally combines with describedbreather 2, and describedgas tube 3 is communicated with describedcover 1, it is characterized in that, describedbreather 2 comprises two sections, and wherein one section is the level and smooth stationary pipes of tube wall 4, and another section is thetelescoping tube 5 of wave-like for tube wall.In the present embodiment, stationary pipes 4 and describedcover 1 combination.
As a kind of improvement, described stationary pipes 4 arranges a circle caulkinggum packing ring 6 with the coupling part of describedtelescoping tube 5.
Referring to Fig. 2, the second embodiment.Be that with the first embodiment difference in the present embodiment, one section ofbreather 2 andcover 1 combination istelescoping tube 5, other structures are identical.
Referring to Fig. 3, the third embodiment.In the present embodiment, cover 1 adopts solid silica gel to make, and does not therefore need to dispose gas tube.
Because the universal and telescopic characteristic oftelescoping tube 5, breather 2 parts are relatively soft, difficulty may appear inserting in inserting the process of laryngeal mask, for handled easily, use a kind oftube core 7 that adapts withbreather 2 to insert in thebreather 2 to increase the shaping ofbreather 2, insert before the laryngeal mask breather 2 bent to the radian that is fit to the patient, insert laryngeal mask and fixing after,extract tube core 7 and get final product.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; that describes in above-described embodiment and the description just illustrates principle of the present utility model; under the prerequisite that does not break away from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements all fall in claimed this utility model scope.The claimed scope of this utility model is defined by appending claims and equivalent thereof
