Abstract

The utility model provides a gastroscope gas filled bushing, includes the hose, install support airbag on the hose, support airbag includes oral cavity gasbag, esophagus gasbag and orifice of the stomach gasbag that outside -in set gradually. Gastroscope gas filled bushing simple structure, practical easy, insert the esophagus after the foreign body sensation little. The oral cavity gasbag supports the oral area, ventilates through the air vent, guarantees patient's breathing, and the texture is softer, avoids interlock muscle to cramp, patient's comfort level when improving the inspection. The esophagus gasbag supports the hose in the esophagus, reduced its and the contact surface of esophagus, lighten its stimulation to the esophagus, has reduced its and the contact surface of esophagus, the bending of being convenient for, and better played a supporting role avoids amazing esophagus to lead to the fact the foreign body sensation, avoids the esophagus internal gas pressure to change that to lead to the fact the esophagus to fill bloated, and what prevent so lead to the fact uncomfortablely feels. Annular beautifully adorned door cylinder is sealed with esophagus and stomach, and the retch formation esophagus of avoiding the foreign body sensation to arouse is palirrhea, avoids palirrhea thing upwards to get into the esophagus, amazing esophagus, and it is pharyngeal also to avoid palirrhea thing rising to enter into the patient, influences the patient and breathes.

Description

Gastroscope blown jacket

Technical field

This utility model relates to a kind of medical apparatus and instruments, specifically, is a kind of gastroscope blown jacket.

Background technology

Gastroscopy is a kind of conventional medical inspection method, stretches in stomach by very thin, a soft pipe, and doctor can directly observe esophagus, the duodenal pathological changes of harmonization of the stomach, especially to small pathological changes.Before doctor is inserted into gastroscope, sleeve pipe to be inserted, it is to avoid when gastroscope moves back and forth in vivo, causes pipe and esophagus friction, stimulates esophagus, increase the foreign body sensation of patient, even galled by esophagus, cause hemorrhage.So needing first to insert sleeve pipe, then gastroscope being inserted in conduit, being then fed into stomach.Owing to esophagus is not straight, having certain camber, sleeve pipe easily swings in esophagus, touches esophagus inwall, still can stimulate to esophagus, and sleeve pipe also can touch the pharyngeal of patient, causes retch.In order to insert sleeve pipe, in addition it is also necessary to first allow patient bite Occluding device, allowing the oral cavity of patient be constantly in open mode, but current Occluding device generally plastics are made, quality is harder, and comfort level is poor, and oral area remains stationary as a long time, easily makes the occlusion crick of patient.

Utility model content

This utility model is for above-mentioned the deficiencies in the prior art, it is proposed that a kind of new gastroscope blown jacket.

Gastroscope blown jacket of the present utility model, including flexible pipe, on described flexible pipe, support air bag is installed, described support air bag includes the oral cavity air bag that ecto-entad sets gradually, esophagus air bag and cardia air bag, described oral cavity air bag is frustum, edge is arc, external diameter is gradually increased from inside to outside, described oral cavity air bag arranges multiple blow vent, described esophagus air bag interval arranges multiple, and in the shape of a spiral, described cardia air bag is ringwise, the cross section of described esophagus air bag and cardia air bag is all oval, described oral cavity air bag, esophagus air bag is connected by the breather being arranged in hose inner wall with cardia air bag.

The beneficial effects of the utility model are: gastroscope blown jacket simple in construction, and practical easily the diameter that can make flexible pipe is less, and after inserting esophagus, foreign body sensation is little.Oral cavity bladder support oral area, is ventilated by passage, it is ensured that the breathing of patient, having certain elasticity, quality is softer simultaneously, in the case of ensureing support effect, enable a certain degree of activity of patient's oral area, it is to avoid occlusion crick, improve the comfort level of patient when checking.Esophagus air bag is at esophagus inner support flexible pipe, reduce the contact surface of itself and esophagus, alleviate its stimulation to esophagus, esophagus air bag is in the shape of a spiral, reduce the contact surface of itself and esophagus, it is easy to bending, can preferably play a supporting role in the esophagus having flexibility, gastroscope in sleeve pipe is avoided to make flexible pipe touch esophagus when moving, avoid stimulating esophagus to cause foreign body sensation, and after esophagus bladder support, can ventilate in the space between esophagus air bag, avoid the change of esophagus internal gas pressure to cause esophagus to inflate, prevent the sense of discomfort thus resulted in.Esophagus is sealed by ring-type cardia cylinder with stomach, it is to avoid the retch that foreign body sensation causes forms esophageal regurgitation, it is to avoid reflux thing is upwardly into esophagus, stimulates esophagus, also avoids reflux thing to rise into patient pharyngeal, affect patient respiratory.Oral cavity cell edges is arc, the cross section of esophagus air bag and cardia air bag is all oval, add the elastic space of each air bag, make air bag quality more soft, can guarantee that again its supporting role simultaneously, itself and patient's esophagus or the contact area in oral cavity can also be reduced, reduce and stimulate and foreign body sensation.

Accompanying drawing explanation

Accompanying drawing 1 is the structural representation of this gastroscope blown jacket.

Detailed description of the invention

In order to be able to further appreciate that structure of the present utility model, feature and other purpose, describing in detail as follows in conjunction with appended preferred embodiment, illustrated preferred embodiment is merely to illustrate the technical solution of the utility model, and non-limiting this utility model.

Detailed description of the invention of the present utility model is as follows:

As it is shown in figure 1, this gastroscope blown jacket includes flexible pipe 1, flexible pipe 1 is provided with support air bag.

Support air bag includes oral cavity air bag 2, esophagus air bag 3 and the cardia air bag 4 that ecto-entad sets gradually.

Oral cavity air bag 2 is frustum, and edge is arc, and external diameter is gradually increased from inside to outside.Oral cavity air bag 2 arranges multiple blow vent 5.

Esophagus air bag 3 interval arranges multiple, and in the shape of a spiral.Cardia air bag 4 is ringwise.

The cross section of esophagus air bag 3 and cardia air bag 4 is all oval, and oral cavity air bag 2, esophagus air bag 3 are connected by the breather being arranged in flexible pipe 1 inwall with cardia air bag 4.

During original state, each support air bag is not all ventilated.First allowing patient's Occluding device to be gone out, then send in esophagus by flexible pipe 1, then the breather QI KOU inflation to flexible pipe outer end, oral cavity air bag 2, esophagus air bag 3 and cardia air bag 4 expand successively, support in the middle part of oral cavity, esophagus respectively and esophagus is inner.The most just gastroscope can be sent in the stomach of patient by sleeve pipe.
