Description

Reinforced two-tube laryngeal mask

Technical field

The utility model is related to medical instruments field, specifically, refers to a kind of air flue for general anesthesia and leads to Gas instrument.

Background technology

For the ventilation instrument of diseases of eye, ear, nose and throat section patient with operation general anesthesia, at present clinically using being exactly at most laryngeal mask. And how from the flexible laryngeal mask facilitating surgeon's operation on laryngeal mask selects, but it exists seriously during clinical manipulation Deficiency, can occur gas leakage and gastric juice to backflow in the patient encountering obesity, airway pressure height and stomach esophageal reflux.And use two-tube larynx instead Cover can drainage gastric juice, prevent gaseous distention, but it expose the impact surgeon's operation of extrabuccal conduit part branch.

In prior art, occur in that the product solving the above problems, two-tube laryngeal mask as flexible in LMA PROSEAL, Get final product drainage stomach tube, it is flexible conduit that conduit is exposed in oral cavity again, facilitates surgeon to operate.But this laryngeal mask practical operation is compared Difficulty, operator needs training and exercise process through the long period；And this laryngeal mask expensive it is impossible to be commonly used to Clinical.

Utility model content

The purpose of this utility model is to solve above-mentioned deficiency of the prior art, provides a kind of reinforced two-tube laryngeal mask, While guaranteeing general anesthesia ventilatory effect, optimize operating process, facilitate the operation of surgeon.

For realizing above-mentioned purpose, technical solution of the present utility model is as follows：

A kind of reinforced two-tube laryngeal mask, its feature is, including cover body, hard shaping conduit, flexible breather pipe, drainage Pipe, breather pipe and inflatable cuff；

One end of described breather pipe is connected with described flexible breather pipe, and the other end passes through described hard shaping conduit It is connected with described cover body, described inflatable cuff is connected with described cover body, described drainage tube is moulded through described hard Shape breather pipe and cover body.

The upper port of described drainage tube is located at the described close flexible breather pipe of the moulding breather pipe of hard, described Drainage tube lower port be located at cover body away from the moulding breather pipe of hard at.

When the utility model uses, because the moulding breather pipe of hard is moulding by human oral cavity physiological curve, place very Simply, only finger need to be pinched the moulding breather pipe of hard directly to insert along patient's physiology of oral cavity curve, then stomach tube is put Enter and in drainage tube, just complete all operationss.And this laryngeal mask exposes portion for flexible breather pipe, surgeon can arbitrarily put, complete Entirely do not interfere with their operation.

The utility model beneficial effect：

Reinforced two-tube laryngeal mask of the present utility model, two-tube laryngeal mask and flexible laryngeal mask are combined, and can ensure that anesthesia is logical On the basis of gas effect, significantly optimize operating process, save the operating time, facilitate the operation of surgeon simultaneously.

Brief description

Fig. 1 is the structural representation of the reinforced two-tube laryngeal mask of the utility model；

Fig. 2 is the use state figure of the reinforced two-tube laryngeal mask of the utility model；

In figure：Flexible breather pipe 1, drainage tube upper port 2, the moulding breather pipe of hard 3, cover body 4, drainage infratubal port 5, Inflatable cuff 6, drainage tube 7.

Specific embodiment

Below in conjunction with drawings and Examples, the technical solution of the utility model is further explained, but following Content is not used in restriction protection domain of the present utility model.

As shown in figure 1, the present embodiment provides a kind of reinforced two-tube laryngeal mask, including cover body 4, hard shaping conduit 3, flexible Breather pipe 1 and inflatable cuff 6, in hard shaping conduit 3 in addition to breather pipe, an also drainage tube 7, its opening respectively draws Flow tube upper port 2 and drainage infratubal port 5, can place stomach tube, one end of breather pipe and flexible breather pipe 1 by this drainage tube It is connected, the other end is connected through institute's hard shaping conduit 3 with cover body 4, and one end of inflatable cuff 6 is connected with cover body 4

In the present embodiment, described laryngeal mask is made using medical grade plastic materials.

As Fig. 2, in the present embodiment, when specifically used, patient lies on the back after needing general anesthesia, and operator's left hand opens patient's mouth Chamber, the right hand is held the moulding breather pipe of hard 3 and is inserted along patient oral cavity, and moulding for hard breather pipe 3 is put in patient's front tooth completely, Then inject after appropriate air toward inflatable cuff 6, flexible breather pipe 1 is connect Anesthesia machine and uses, finally by drainage tube upper end Mouth 2 inserts stomach tube, places appropriate depth through after drainage infratubal port 5.Whole process is simple, the moulding breather pipe of hard 3 It is easy to operator and insert laryngeal mask；It is flexible breather pipe 1 outside front tooth, be easy to surgeon's operation technique.Drainage tube can put stomach tube Drainage gastric juice and gas, reduction of patient gaseous distention, mitigate airway pressure.

Although content of the present utility model has been made to be discussed in detail by above preferred embodiment, but it should be appreciated that on The description stated is not considered as to restriction of the present utility model.After those skilled in the art have read the above, for Multiple modifications and substitutions of the present utility model all will be apparent from.Therefore, protection domain of the present utility model should be by appended Claim limiting.
