Abstract
An anti-reflux laryngeal mask is characterized by comprising a vent hood bag, a ventilating tube, a gastric tube channel and a suction pipeline. The vent hood bag is integrated with the ventilating tube, the gastric tube channel stretches into one side of the ventilating tube, extends to the top of the vent hood bag, and is connected with a gastric tube channel opening arranged on the top of the vent hood bag, the suction pipeline is arranged inside the vent hood bag, at least one suction pipeline opening is arranged beside the gastric tube channel opening, and the suction pipeline is connected with a hollow drainage tube and extends out of the top of the vent hood bag. By the anti-reflux laryngeal mask, possibility of reflux aspiration can be greatly reduced, and the service safety of the laryngeal mask is improved. Besides, during positive-pressure ventilation, the anti-reflux laryngeal mask can prevent gas from entering the stomach of a patient to cause gaseous distention, and physical suffering of the patient after a surgery is reduced.
Description
Technical field
The present invention relates to a kind of medical care apparatus, be specifically related to a kind of anti-reflux type laryngeal mask.
Background technology
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.
It is one of contingent severe complication of laryngeal mask airway that mistake is inhaled, though incidence rate is low, prognosis is very poor.Can not close fully because the construction features of laryngeal mask, its position of inserting lower pharyngeal cavity can cause esophageal sphincter, air flue can not be definitely airtight.Therefore, when a variety of causes caused that intra-abdominal pressure or gastric pressure increase, gastric content easily backflowed into esophagus, and further upwards backflows to esophagus porch even oral cavity, and subsequently, the thing that backflows can suck in the trachea with the positive airway pressure mistake.Therefore, can not prevent that gastric content from backwards flowing and mistake from inhaling is that at present all laryngeal masks all exist a fatal shortcoming.
Summary of the invention
Technical problem solved by the invention is to provide a kind of anti-reflux type 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 anti-reflux type laryngeal mask, comprise vent hood capsule, breather, gastric tube passageway and attraction pipeline, described vent hood capsule and described breather integrally combine, described gastric tube passageway is stretched into by a side of described breather, and extend to the tip of described vent hood capsule, and the most advanced and sophisticated gastric tube passageway opening that arranges of connection vent hood capsule, it is inner that described attraction pipeline is arranged at described vent hood capsule, and in other at least one the attraction pipeline opening that is provided with of the side of gastric tube passageway opening, described attraction pipeline connects one section hollow drainage tube, and extends out from the top of described vent hood capsule.
As a kind of improvement, described breather adopts silica gel or rubber to make.
As a kind of design of routine, inside is shaped with intensity and the suppleness that helical metal wire (perhaps other hard material taenidiums) is used for increasing tube wall in advance in the tube wall of described breather.Near section of breather has standard ventilation ring pipeline connector, can be connected with the ventilation loop.
As a kind of improvement, described vent hood capsule is the Oblique Elliptic taper, can be that the hollow gasbag that thin soft silica gel or rubber are made forms, and also can be that solid silica gel is moulding makes.
As a kind of improvement, described gastric tube passageway and attraction pipeline adopt medical plastic to make.
As a kind of improvement, described hollow drainage tube is connected with negative pressure suction device.
As a kind of improvement, when described vent hood capsule adopted thin soft silica gel or rubber to make, described vent hood capsule was provided with gas tube, was used for inflating in the vent hood capsule of hollow bleeding, and regulated the pressure in the vent hood capsule.
Principle of the present invention is as follows.Can insert stomach tube by gastric tube passageway attracts gastric content to reduce the gastric pressure; And when ventilating in the vent hood capsule, attraction pipeline can utilize hollow drainage tube connection negative pressure suction device to attract, and prevents that effectively the thing mistake of backflowing of esophagus porch from sucking trachea.
Owing to having adopted above structure, the present invention has following beneficial effect:
The present invention can with may greatly reducing that the mistake of backflowing is inhaled, improve the safety that laryngeal mask uses.In addition, when positive airway pressure, the present invention can prevent that also gas from entering gastric and causing flatulence, has reduced the misery on patient's postoperative health.
Description of drawings
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.
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 concrete diagram, further set forth the present invention.
Be the first embodiment of the present invention referring to Fig. 1, a kind of anti-reflux type laryngeal mask, comprise vent hood capsule 1, breather 2, gastric tube passageway 3 and attraction pipeline 4, described vent hood capsule 1 and described breather 2 integrally combine, described gastric tube passageway 3 is stretched into by a side of described breather 2, and extend to the tip of described vent hood capsule 1, and the connection vent hood capsule 1 most advanced and sophisticated gastric tube passageway opening 5 that arranges, described attraction pipeline 4 is for being arranged at the circulating line of described vent hood capsule 1 inside, and the side side in gastric tube passageway opening 5 is provided with two attraction pipeline openings 6, described attraction pipeline 4 connects one section hollow drainage tube 7, and extends out from the top of described vent hood capsule 1.
In the present embodiment, described breather 2 adopts silica gel to make, and inside is shaped with helical metal wire 8 in advance in the tube wall of described breather 2, is used for increasing intensity and the suppleness of tube wall, and near section of breather 2 has standard ventilation ring pipeline connector 9, can be connected with the ventilation loop.
In the present embodiment, described vent hood capsule 1 is the Oblique Elliptic taper, is the hollow gasbag that adopts thin soft silica gel to make, and described vent hood capsule 1 is provided with gas tube 10, is used for bleeding to the vent hood capsule 1 interior inflation of hollow, regulates the pressure in the vent hood capsule 1; And described gastric tube passageway 3 and attraction pipeline 4 adopt medical plastic to make, and described hollow drainage tube 7 is connected with negative pressure suction device 11.
