Abstract
The utility model provides a laryngeal mask for blocking esophagus, which consists of a laryngeal mask breather pipe, a stomach tube channel, a mask bag and a mask bag inflatable tube, wherein the end part of the mask bag is connected with a section of hollow esophagus tube which is provided with an inflatable sleeve bag, and the inflatable sleeve bag is connected with an inflatable valve through an inflatable pipeline. As for the laryngeal mask for blocking esophagus, the inflatable sleeve bag is arranged at the end part of the mask bag, when the inflatable sleeve bag is filled with gas, the esophagus of a patient can be completely blocked, and the connection between the stomach part and the throat part as well as the respiratory tract can be suspended, so that the phenomena of backflow and aspiration of contents in the stomach can be avoided; and when positive pressure ventilation is conducted, gas can be prevented from entering the stomach to cause gastrectasia, so that complications generated by using the laryngeal mask are greatly reduced, the pain of the body of the patient is reduced, and the using range of the laryngeal mask is widened.
Description
Technical field
This utility model relates to medical laryngeal mask, and a kind of specifically esophagus stops up laryngeal mask.
Background technology
Laryngeal mask is to use more a kind of breathing equipment in the clinical anesthesia, particularly in to the less demanding small-sized operation of flesh pine, use more, the use of laryngeal mask is fairly simple, do not need to use the auxiliary bottleneck throat that can insert patient of muscle relaxant and laryngoscope, stimulation to patient is less, and patient can keep autonomous respiration at operation process.
See also Fig. 1, be the wherein structural representation of a laryngeal mask in the known technology.Clinical employed laryngeal mask generally is made up of laryngeal mask snorkel 10, gastric tube passageway 20, cover capsule 40 and cover capsule gas tube 30 at present.When operation, laryngeal mask is inserted patient's bottleneck throat, cover capsule 40 places patient's respiratory tract and gastral intersection, inflate by 30 pairs of covers of cover capsule gas tube capsule 40, the airtight larynx of cover capsule after the inflation forms airtight passage and ventilates, but, the laryngeal mask of this kind structure in use, respiratory tract and the digestive tract that can not separate patient fully, thereby can't stop gastric content backflows, the possibility that mistake is inhaled, can only be by placing stomach tube drain gastric content, reducing gastric content to a certain extent backflows, can not fundamentally stop gastric content backflows, mistake is inhaled, and because digestive tract and respiratory tract can not be separated fully, also causes gas to enter gastrointestinal tract easily when implementing positive airway pressure, causing gastric to be pressed increases, easier initiation gastric content backflows, and the rising of gastric pressure simultaneously also can cause airway pressure to raise, and influences ventilatory effect.
The utility model content
At above the deficiencies in the prior art and defective, the purpose of this utility model is to provide a kind of esophagus to stop up laryngeal mask.
The purpose of this utility model is achieved by the following technical solution:
A kind of esophagus stops up laryngeal mask, is made up of laryngeal mask snorkel, gastric tube passageway, cover capsule and cover capsule gas tube, and described cover capsule end connects the food meatus of one section hollow, and this food meatus is provided with inflatable cuff, and this inflatable cuff is connected with charging valve by aerating pipe.
As optimal technical scheme of the present utility model, the length of described food meatus is 5cm.
As optimal technical scheme of the present utility model, described inflatable cuff is ellipticity.
Compared with prior art, the cover capsule end that this utility model esophagus stops up laryngeal mask is provided with inflatable cuff, behind this inflatable cuff gassy, can stop up patient's esophagus fully, interrupt being connected between stomach and bottleneck throat, the respiratory tract, avoid taking place the phenomenon that gastric content backflows, mistake is inhaled, when positive airway pressure, can prevent that also gas from entering gastric and causing flatulence, significantly reduced the complication of using laryngeal mask, reduce the misery on the patient body, widened the scope of application of laryngeal mask.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is the wherein structural representation of a laryngeal mask in the known technology.
Fig. 2 stops up the structural representation of laryngeal mask for this utility model esophagus.
Fig. 3 stops up the use sketch map of laryngeal mask for this utility model esophagus.
The specific embodiment
See also Fig. 2, stop up the structural representation of laryngeal mask for this utility model esophagus.This esophagus stops up laryngeal mask, comprise laryngeal mask snorkel 101, gastric tube passageway 102, cover capsule 104 and cover capsule gas tube 103, these cover capsule 104 ends connect the hollow food meatus 105 that a segment length is 5cm, this food meatus 105 is provided with inflatable cuff 106, this inflatable cuff 106 is connected with charging valve 108 by aerating pipe 107, is ellipticity behind these inflatable cuff 106 gassies.
Please continue to consult Fig. 3, stop up the use sketch map of laryngeal mask for this utility model esophagus.During operation, this esophagus is stopped up laryngeal mask put into patient's bottleneck throat, cover capsule 104 places the intersection of patient's respiratory tract 109 with digestive tract 110, and food meatus 105 that cover capsule 104 ends connect and the inflatable cuff 106 on the food meatus 105 stretch in the digestive tract 110.After esophagus obstruction laryngeal mask is correctly put into patient's body, in cover capsule 104 and inflatable cuff 106, inject air respectively by gas tube 103 and aerating pipe 107, make its volume become big, the 104 sealing larynx ventilations of cover capsule, inflatable cuff 106 is stopped up esophagus fully, being connected between blocking-up stomach and bottleneck throat, the respiratory tract 109, avoid taking place that gastric content backflows, the mistake suction.
Claims (3)
1. an esophagus stops up laryngeal mask, form by laryngeal mask snorkel, gastric tube passageway, cover capsule and cover capsule gas tube, it is characterized in that: described cover capsule end connects the food meatus of one section hollow, and this food meatus is provided with inflatable cuff, and this inflatable cuff is connected with charging valve by aerating pipe.
2. esophagus according to claim 1 stops up laryngeal mask, and it is characterized in that: the length of described food meatus is 5cm.
3. esophagus according to claim 1 stops up laryngeal mask, and it is characterized in that: described inflatable cuff is ellipticity.
