Abstract
A universal retractable laryngeal mask comprises a mask surface and a ventilating tube. The mask surface and the ventilating tube are integrated, and the ventilating tube comprises a fixing tube with a smooth tube wall and a retractable tube with a corrugated tube wall. The universal retractable laryngeal mask is simple in structure, and can effectively adapt to change of positions of the head and the neck of a patient, so that the quality of medical care is improved.
Description
Technical field
The present invention relates to a kind of medical instruments, be 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 power high, 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 easily is shifted because of the variation of incidence position, 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 easily to be shifted and leaks gas, and jeopardizes patient safety.
Summary of the invention
Technical problem solved by the invention is to provide a kind of Universal telescopic laryngeal mask, thereby solves the problem in the above-mentioned background technology.
Technical problem solved by the invention 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 tube wall undulate shape.
Among the present invention, described breather be combined with cover a section adopts stationary pipes or telescoping tube all can.That is to say, the version that can adopt has two kinds: a kind of is one section stationary pipes that tube wall is level and smooth that breather is combined with cover, and a section of being combined with cover is the telescoping tube of tube wall undulate shape and another kind is breather.
Among the present invention, 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 maximum of the present invention 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 having adopted above technical scheme, the present invention has following beneficial effect:
The present invention is simple in structure, can make laryngeal mask better adapt to the incidence change in location, has improved medical and nursing quality.

Fig. 1 is the structural representation of the first embodiment of the present invention.
Fig. 2 is the structural representation of the second embodiment of the present invention.
Fig. 3 is the structural representation of the third embodiment of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with specific embodiment, further set forth the present invention.
Referring to Fig. 1, the first embodiment.A kind of Universal telescopic laryngeal mask, comprise cover 1 and breather 2, in the present embodiment, also comprise gas tube 3, described cover 1 integrally combines with described breather 2, and described gas tube 3 is communicated with described cover 1, it is characterized in that, described breather 2 comprises two sections, and wherein one section is the level and smooth stationary pipes of tube wall 4, and another section is the telescoping tube 5 of wave-like for tube wall.In the present embodiment, stationary pipes 4 and described cover 1 combination.
As a kind of improvement, described stationary pipes 4 arranges a circle caulking gum packing ring 6 with the coupling part of described telescoping tube 5.
Referring to Fig. 2, the second embodiment.Be with the first embodiment difference, in the present embodiment, one section of breather 2 and cover 1 combination is telescoping tube 5, and 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 configure gas tube.
Because the universal and telescopic characteristic of telescoping 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 of tube core 7 that adapts with breather 2 to insert in the breather 2 to increase the shaping of breather 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.
Above demonstration and described ultimate principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof
