Description

Two capsule tracheal intubatioies

Technical field

This utility model belongs to medical instruments field, relates to a kind of tracheal intubation, is specifically related to a kind of two capsule tracheal intubatioies for surgery anesthesia and critical patient rescue.

Background technology

Tracheal intubation is used in clinical medicine extensively, as heart recovery, with the anxious Cavity in Critical Patients emergency surgical operation of respiratory disorder, general anesthesia operation etc.Tracheal intubation is important medical supplies commonly used in rescue service, is to use the most extensive, the most quick, one of the most effective medical apparatus and instruments in management of respiratory, to rescue patient life, reduce case fatality rate and played vital effect.

There are some design defect in traditional tracheal intubation, makes medical personnel to difficult grasp the in insertion depth position of tracheal intubation, and blood tissues liquid easily flows into air flue or esophagus.General doctor can by virtue of experience control insertion depth and position, or with the implant of gauze class, tracheal intubation is fixed on throat, prevents that blood, secretions, foreign body etc. in operation process from entering the throat depths, obstruction respiratory tract or enter esophagus.But malpractice thus is a lot, has serious medical hidden danger.

In recent years the 26S Proteasome Structure and Function of tracheal intubation improved, design two capsule tracheal intubation Patents documents as follows: Chinese utility model patent description " single-cavity double-pocket tracheacannula conduit ", Granted publication CN2617396Y on May 26 2004 Granted publication day, has disclosed: a kind of clinical single-cavity double-pocket tracheacannula conduit of using, by single-lumen bronchial tube, conduit outlet, conduit side opening, two air bags, air bag fills, and venting pore and charge valve consist of.This pair capsule is independent each other, can intersect to exit and inflation.

Its advantage: can prevent that oral secretion or esophageal reflux thing from entering trachea and lung, reduce the damage that air bag causes the inner surface of trachea compressing, alleviate patient's infringement and minimizing patient's expense

Weak point: described single-cavity double-pocket tracheacannula conduit is all for sealing patient trachea, can't stop that oral cavity inner blood, secretions, foreign body etc. enter the throat depths.

Chinese utility model patent description " single-cavity two-bag positioing tracheal catheter ", Granted publication CN2770684Y, April 12 2006 Granted publication day, the main points of its technical scheme are, the rear end of endotracheal tube is connected with connection tube, and front end is with cuff, and cuff is connected with draught excluder by the cover ductus bursae, with the location cuff, the location cuff is connected with draught excluder by the cover ductus bursae at the tail side of cuff.

Its advantage: the design of cuff is convenient accurately locates.

Weak point: can't stop that oral cavity inner blood, secretions, foreign body etc. enter the throat depths.

At present, Medical Device Market demands developing a kind of two capsule tracheal intubatioies with large sacculus urgently, realizing the sealing to the patient oral cavity, and then prevents that oral cavity inner blood, secretions, foreign body etc. from entering the throat depths.The molding of sacculus is very difficult greatly for silastic material, thereby has hindered the development of two capsule tracheal intubatioies.

The utility model content

The purpose of this utility model, to provide a kind of two capsule tracheal intubatioies safely and effectively for clinical treatment and surgical operation, this pair capsule tracheal intubation makes tracheal intubation be fixed on accurately patient throat by large sacculus, and prevents that blood, secretions, foreign body etc. in operation process from entering air flue or esophagus.The doctor can detect aeration quantity and the blowing pressure by pressure indicator, has improved the handling and safety for the treatment of, thereby has overcome the defective of prior art.

This utility model for achieving the above object, the technical scheme that adopts is:

A kind of pair of capsule tracheal intubation, comprise the patient end joint, little sacculus, strengthen breather, connector, gas source connector, gas tube and pressure indicator, it is characterized in that: be positioned at and strengthen breather and be provided with large sacculus for the approximate ellipsoidal that adapts with the human body bottleneck throat, the structure of described large sacculus is made of a parts and b parts, wherein the version of b parts is designed with two kinds of multi-form structures: a kind of b parts of the form that is structure as a whole, another kind are by c parts and the common bonding b parts that form of d parts.

Described a parts, one end are provided with a circle groove, and are connected smooth-going with b parts front opening place, and are bonded as one with binding agent is airtight.

Described large sacculus, its diameter is designed to 5cm～10cm.

Described large sacculus, its material are medical grade silicon rubber.

Beneficial effect

Compared with prior art, the beneficial effects of the utility model: 1, due to a kind of two capsule tracheal intubatioies with large sacculus of design, thereby realization is to the sealing in patient oral cavity, and then prevents that oral cavity inner blood, secretions, foreign body etc. from entering the throat depths.2, make tracheal intubation be fixed on accurately patient throat by large sacculus, and prevent that blood, secretions, foreign body etc. in operation process from entering air flue or esophagus.3, operator detect aeration quantity and the blowing pressure by pressure indicator, have improved the handling and safety for the treatment of.
