Abstract

The utility model discloses an air filling device for lightening the excitation of endoscopes, which is composed of a cylindrical and sealed air filling bag and a guiding air filling tube. When the utility model is used, the air filling bag in which air is not filled yet is brought into a mouth by the guiding air filling tube, and after air filling, the air filling bag is fixed at the throat position to form a cylindrical passageway. A medical endoscope enters a human body for examination through the inner wall of the cylindrical passageway. The utility model has the advantages that the structure is simple, the use is convenient, adverse stimulation reactions caused by endoscopes to the throat parts of patients are furthest reduced, the examination of people by using endoscopes becomes safe, comfortable, and positive, etc. The utility model overcomes the defects existing in the prior art very well and is an ideal auxiliary device used when a medical endoscope is used for examination.

Description

A kind of aerating device that alleviates endoscope's stimulation

This utility model relates to a kind of medical going up as alleviating patient's a kind of protector that endoscope reacts the pessimal stimulation that body produced when carrying out the sight glass inspection that be mainly used in.

The widely-used various endoscopies of medical profession carry out disease examination at present, comprise gastroscope, duodenoscope etc.These all can be through the very responsive bottleneck throat of body when entering body and checking; its by the time can cause by a relatively large margin friction and stimulation, the nauseating reaction that mucosal tissue very widely can produce protectiveness to the stimulation of endoscope that distributes that bottleneck throat is neural.Severe patient even reactions such as reflexive cardiac arrest can take place, simultaneously because the gastrointestinal motion that the reaction of feeling sick is caused makes endoscope to influence the inspection effect in the short stay body, a part of patient after inspection also can because of mucosa injury, hemorrhage influence swallow, feed etc.In order to alleviate above-mentioned reaction, medical profession all adopts before splanchnoscopy in the throat localized ejection or gulps down and contains topical anesthetic cream usually.This method can only alleviate severe complication, and the topical anesthesia itself of bottleneck throat simultaneously can be made patient's bottleneck throat numbness and be felt sick and wait reaction, so this method is difficult to fundamentally solve the stimulation of endoscope to patient.

The purpose of this utility model just is to provide a kind of aerating device of the patient's of alleviating stimulation, with its just using method and reduce endoscope dramatically and pharyngeal contacting structure, thereby make patient under safer, comfortable condition, accept splanchnoscopy, avoid endoscope to contact the unnecessary damage that is caused with body tissue, also have the effect that makes things convenient for the calm inspection of doctor.

The purpose of this utility model realizes that by following measure this aerating device mainly comprises a gas cell and a guiding gas tube that is tubular and sealing and forms.The wherein inwall of tubular gas cell, outer wall, last top, lower bottom part all are to be made by the material with toughness and flexibility, and the last top opening place of gas cell is a collar extension that is the convex edge shape; The bottom of guiding gas tube is inserted among the gas cell, and top is positioned at outside the gas cell, is mounted with inflation interface and stopper at the upper end that guides gas tube.

Tubular gas cell in this utility model can be made by the thin film of polrvinyl chloride, polyethylene, polypropylene, polyurethane, nylon and nontoxic rubber.

Its diameter of guiding gas tube in this utility model is φ 3～φ 7mm, and should guiding gas tube inserts uniform some exhaust holes on the tube wall of the bottom in gas cell at it.

Adopt tubular aerating device of the present utility model, owing to adopted the soft low pressure air bag of convenience inflation, when just making endoscope in entering body, enter and directly do not contact and rub by the inner wall section of air bag with the widely distributed pharyngolaryngeal mucosa of teleneuron, this physical property is isolated just to make endoscope that the stimulation of body is alleviated significantly, and the large tracts of land even contact of tubular air bag and mucosa can make air bag can not move when checking and can not produce irritant reaction simultaneously.The guiding gas tube then can make air bag arrive at appointed part smoothly and that inflation, venting are moved is more easy to operate, also can allow air bag withdraw from bottleneck throat smoothly after the inspection.The tubular aerating device that this patient of alleviating stimulates is a kind of very ideal splanchnoscopy assistant product.

Accompanying drawing is a kind of enforcement structural representation of the present utility model.

Below in conjunction with drawings and Examples this utility model being done a step describes:

This aerating device is mainly organized by gas cell that is tubular and sealing (1) and guiding gas tube (3) that polyethylene is made as shown in the figure.And the last top opening place of this tubular gas cell (1) is a collar extension (6) that is the convex edge shape.It can guarantee tubular gas cell (1) after inflation, and its upper top definitely is in the opening shape, can allow endoscope insert very easily.Diameter is that the bottom of the guiding gas tube (3) of φ 4mm is inserted among the inside and outside wall of tubular gas cell (1), and this guiding gas tube (3) seals the jail with the part that contacts that tubular gas cell (1) is gone up the top with encapsulant.And uniform some exhaust holes (2) on the tube wall of guiding gas tube (3) bottom.Be mounted with inflation interface (4) and stopper (5) at the upper port place of guiding gas tube (3) in addition.

This aerating device in use, at first the gas in the tubular gas cell is fully exhausted with a syringe, make gas cell in, outer wall closely contacts to reduce volume with the guiding gas tube, be coated with lubricant and a small amount of local anesthetic on its surface, allow patient swallow bottleneck throat and esophagus voluntarily, after the guiding gas tube enters certain depth, to charge into a certain amount of gas by inflation inlet and make its expansion in the tubular gas cell and contact fixing with the body mucosa, at this moment preparation is finished, and endoscope can be entered in the gastrointestinal by the collar extension of tubular gas cell by the oral cavity and check.The length of tubular gas cell is exceeded and is got final product to cross nerve distribution area.Check that back endoscope withdraws from, take out the stopper venting again, after the tubular gas cell is loose can by the guiding gas tube all device withdraw from external, thereby reach the purpose of this utility model.

Claims

1. the aerating device that alleviates endoscope stimulation formed of gas cell by tubular and sealing (1) and guiding gas tube (3), it is characterized in that tubular gas cell (1) inwall, outer wall, Shang Ding, to go to the bottom all be that material by having toughness and flexibility is made, and the last top opening place of gas cell (1) is a collar extension (6) that is the convex edge shape; The bottom of guiding gas tube (3) is inserted among the gas cell (1), and top is positioned at outside the gas cell (1), is mounted with inflation interface (4) and stopper (5) at the upper port place of guiding gas tube (3) simultaneously.
