Description
Technical field
The utility model is related to a kind of laryngeal masks.
Background technology
Currently known laryngeal mask is divided into two classes, and one kind is inflatable laryngeal mask, and one kind is to exempt to inflate laryngeal mask.Inflatable laryngeal mask is adopted
With air bag, laryngeal mask is put into after patient throat, air bag is inflated, reached after airbag aeration and dissected at the atrium of larynx with patient
Structure forms sealing, and inflatable laryngeal mask has the shortcomings of for example troublesome in poeration, sealing performance is poor, therefore a new generation occurs
Exempt to inflate laryngeal mask（Such as SLIPA laryngeal masks）, i.e., the laryngeal mask as disclosed in the Chinese invention patent of Patent No. 01812838.6.So
And without drainage tube.
The content of the invention
In order to overcome the above-mentioned deficiency of existing laryngeal mask, the utility model provides a kind of laryngeal mask with drainage tube.
The technical scheme in the invention for solving the technical problem is：A kind of larynx with drainage tube
Cover, including a tool there are one the airway of rear end and a front end, the front end of the airway is by one
Flexible saccular chamber is surround, and the front of the flexibility saccular chamber offers blow vent, and the rear of the blow vent is equipped with across institute
The spine of the protrusion of flexible saccular chamber is stated, two head height of spine, centre are low, so as to form circle at the both ends of the spine
Sliding plush copper, it is characterised in that：The front end of the flexibility saccular chamber offers through hole, the flexible saccular chamber and ventilation
There is drainage tube in conduit, the drainage tube is connected with the through hole.
Further, a reinforcement along its length is equipped in the flexible saccular chamber to be oriented to
Muscle, the drainage tube are located at the one side of the reinforcement guiding rib.
Further, the upper end of the guiding reinforcement rib and the upper surface phase of the flexible saccular chamber
Even, the lower end of the guiding reinforcement rib is connected with the lower surface of the flexible saccular chamber.
Further, guiding reinforcement rib extends forwardly into described from the rear end of the flexible saccular chamber
At the blow vent of flexible saccular chamber.
Further, the inside of the through hole is equipped with the connecting tube communicated therewith, the drainage tube insertion connection
Connecting tube connection described in Guan Houyu.
The beneficial effects of the utility model are：There is provided drainage tubes, can prevent gaseous distention by draining Tube Drain gastric juice
It is inhaled by mistake with backflowing.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the structure diagram of flexible saccular chamber and airway.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
1. with reference to Fig. 1, Fig. 2, a kind of laryngeal mask with drainage tube, including a tool leading to there are one rear end and front end
Airway 1, the front end of the airway 1 are surround by a flexible saccular chamber 2, and the front of the flexibility saccular chamber 2 is opened
Equipped with blow vent 3, the rear of the blow vent 3 is equipped with the spine 4 of the protrusion across the flexible saccular chamber, the spine 4
Two head heights, centre are low, and so as to form round and smooth plush copper 5 at the both ends of the spine 4, the shape of this kind flexibility saccular chamber makes
Used time can reach effective sealing with patient rear portion.The front end of the flexibility saccular chamber 2 offers through hole 6, the flexibility
There is drainage tube 7 in saccular chamber and airway, the drainage tube 7 is connected with the through hole 6.It is described logical in this implementation
The inside in hole 6 is equipped with the connecting tube 8 that communicates therewith, and the drainage tube 7 is inserted into after the connecting tube 8 and the connecting tube
8 connections, the connection of drainage tube 7 are more convenient, naturally it is also possible to using other connection methods.
Due to being provided with drainage tube 7, can gastric juice be drained by drainage tube 7, prevent from gaseous distention and backflow to inhale by mistake.
A reinforcement guiding rib 9 along its length is equipped in flexible saccular chamber 2 described in the present embodiment, it is described
Drainage tube 7 is located at the one side of the reinforcement guiding rib 9.When carrying out the connection of drainage tube 7, drainage tube 7 is inserted into airway
And flexible saccular chamber, drainage tube 7 can be pushed ahead along the reinforcement guiding rib 9, have guiding role to drainage tube 7.Simultaneously
Strengthen guiding rib 9 also with the reinforcement effect to flexible saccular chamber 2, it is made to be not easy to cave in.
In the present embodiment, the upper end of the guiding reinforcement rib 9 and the flexible saccular chamber 2
Upper surface is connected, and the lower end of the guiding reinforcement rib 9 is connected with the lower surface of the flexible saccular chamber 2, makes it
Reinforcement effect becomes apparent from.Guiding reinforcement rib 9 extends forwardly into described soft from the rear end of the flexible saccular chamber 2 in the present embodiment
At the blow vent 3 of property saccular chamber, become apparent from its guiding role.
