Abstract

The invention relates to a novel trachea intubation tube. The novel trachea intubation tube aims at solving the defects that an existing trachea intubation tube is easy to block after an operation, a glottis is easy to injure when the existing trachea intubation tube is replaced, laryngeal edema is easy caused, and finally intubation difficultly is increased, and even intubation fails, and furthermore intubation tube indwelling time is long, and pneumonia related to a respirator catheter is high in occurrence rate. For solving the above technical problems, the novel trachea intubation tube comprises three portions of a metal sleeve, a disposable plastic inner sleeve and a disposable plastic outer sleeve. The novel trachea intubation tube is characterized by being supported through the metal sleeve, and used in combination with air sacs on the plastic inner sleeve and the plastic outer sleeve, sealing the inner sleeve and the outer sleeve with peripheral structures, not only achieving the purpose of building an artificial airway of a common trachea intubation tube, but also simultaneously achieving the purposes that the inner sleeve and the outer sleeve can be conveniently replaced at any moment, avoiding tube blocking, reducing the occurrence rate of the pneumonia related to the respirator catheter, and preventing the risk that the glottis and a throat are injured due to repeated tube insertion from occurring, and furthermore has the advantages of being environmentally friendly, and low in use cost due to the fact the metal sleeve can be repeatedly disinfected and used.

Description

Improvement tracheal intubation

Technical field

This patent relates to medical device technical field, is specifically related to a kind of new medical tracheal intubation.

Background technology

In curative activity, endotracheal intubation be a kind of conventional, fast and effectively artificial airway set up measure.The disposable pneumo cannula used at present clinically, although can set up artificial airway in time, postoperative intubate very easily blocks.And when repeatedly changing intubate, significantly increase laryngeal edema, glottis damage and intubation defeat risk; In addition, intubate indwelling time is long, causes sputum accumulation in intubate, increase plugging and the Ventilator Associated Pneumonia (tracheal intubation mainly polluted, sputum sucks caused repeatedly) Probability, thus extend length of patient stay, increase hospitalization cost, even affect final prognosis.

Summary of the invention

The object of this patent is the deficiency and shortcoming that exist for prior art, there is provided a kind of opposed configuration brief, easy to use, associated components is detachable, replacing, and members is sterilized simply, can be recycled, the Medical trachea cannula of Clinical practice expense relative moderate, environmental protection.

The technical scheme of this patent is: a kind of new medical tracheal intubation, comprises metal canula, disposable plastic inner sleeve and trocar sheath three part composition.Supported by metal canula, in conjunction with the air bag on plastics inner sleeve and trocar sheath, internal and external casing all can be sealed with surrounding structure, both realized the object that common tracheal intubation sets up artificial airway; Reach simultaneously inner sleeve can at any time, be convenient for changing, avoid plugging and reduce conduit pneumonia incidence rate, and there is not the risk of repeated intubation damage glottis and larynx; And metal canula can be sterilized use repeatedly, there is more environmental protection, advantage that cost of use is cheaper.

Embodiment 3

See Fig. 3, plastics inner sleeve of the present invention is made up of the plastics that hardness is moderate, and lower end is inclined-plane, right side opening 23, and upper end is respirator interface 25, and centre is the constriction ring 26 be connected with disposable plastic trocar sheath, the metal wire 24 that side has an x-ray to penetrate.

Embodiment 4

See Fig. 4, structural representation after the inside and outside sleeve pipe of disposable plastic of the present invention and metal canula three incorporating aspects.

Embodiment 5

The present invention uses under aseptic principle, first after air tight for 1, No. 2 airbag aeration determination air bag, take out most gas, disposable plastic trocar sheath is enclosed within metal canula lower end, static line 3 is fixed on inside dome-type bulging cap 12, static line 4,6,8 is individually fixed in outside dome-type bulging cap 14,15,17, then inserts in metal canula by disposable plastic inner sleeve, inserts trachea seal wire, after overall plastotype, carry out tracheal intubation operation.

Embodiment 6

When need change tracheal intubation inner sleeve, a set of new trachea tube of aseptic lower preparation.The gas in most air bag 1 is taken out with syringe after suction sputum, the inner sleeve that taking-up need be changed, inserts new inner sleeve along metallic sheath tube chamber, then after injecting proper amount of gas with syringe in air bag 1, inner sleeve upper end 25 is connected with breathing circuit, completes the disposable inner sleeve destroyed after changing and take out.
