Abstract

The utility model discloses a tracheal catheter with double inflation cuffs, which includes a tracheal catheter (1), an upper inflation cuff (2) and a lower inflation cuff (3), and is characterized in that inflation pipes (4) and (8) are arranged on the wall of the tracheal catheter; an air outlet (6) of the inflation pipe (4) is formed inside the upper inflation cuff (2); an air outlet (7) of the inflation pipe (8) is formed inside the lower inflation cuff (3); air inlets of the inflation pipes (4) and (8) are connected with a tee (9); and an air inlet pipe (10) is arranged on the tee (9). The utility model has the advantages that the upper and the lower inflation cuffs in the using process can separately or simultaneously increase or reduce air pressures of the double inflation cuffs through the tee (9), so that the upper and the lower inflation cuffs have different or same pressures, the tracheal catheter can be applied in short time, and the problem that the inflation cuffs generate continuous pressure on the same part of the inner wall of the trachea and damage the tracheal wall during the long time use of the ordinary tracheal catheter is solved.

Description

A kind of pair of inflatable cuff endotracheal tube

Technical field

This utility model belongs to medical apparatus and instruments, and definite saying is a kind of pair of inflatable cuff endotracheal tube.

Background technology

There are a large amount of patients to need long-time indwelling endotracheal tube at present so that keep airway patency or the row mechanical ventilation, because continuing extruding to the same position of tracheal wall, single inflatable cuff of present common endotracheal tube makes the tracheal wall ischemic injuries easily, severe patient may cause the trachea local necrosis, this just need regularly exit to inflatable cuff, to improve the tracheal wall local blood circulation.But, two drawbacks will appear like this: the first, can not carry out mechanical ventilation because of gas leakage between endotracheal tube and the tracheal wall, and cause patient's anoxia; The second, enter pulmonary between oral cavity endocrine meeting transtracheal catheters and the tracheal wall, cause mistake to inhale.Do research in earnest in order to address this problem designer of the present utility model, proposed goal of the invention of the present utility model.

Summary of the invention

Goal of the invention of the present utility model puts forward for the deficiency that overcomes present endotracheal tube monosaccate existence.A kind of pair of inflatable cuff endotracheal tube promptly is provided.

Technical solution of the present utility model is to realize like this, this pair inflatable cuff endotracheal tube, has endotracheal tube, last inflatable cuff and following inflatable cuff, have two gas tubes on the endotracheal tube wall, the gas outlet of a gas tube is in last inflatable cuff, in the gas outlet infra inflatable cuff of another gas tube, the air inlet of gas tube connects threeway, has an air inlet pipe in threeway.

Beneficial technical effects of the present utility model is: increase or reduce the gas pressure in two inflatable cuff simultaneously, use as common endotracheal tube.When long-time indwelling endotracheal tube, when needing venting to improve the blood vessel wall blood circulation, only make one of them inflatable cuff venting, after this inflatable cuff place tracheal wall blood circulation improves, make this inflatable cuff inflation again and make another inflatable cuff venting, after this inflatable cuff place tracheal wall blood circulation also improves, increase the gas pressure in two inflatable cuff simultaneously, this endotracheal tube has used as common endotracheal tube again like this.Thereby can avoid owing to single inflatable cuff produces the problem that the pressure that continues damages tracheal wall at the same position of tracheal wall.

Description of drawings

Accompanying drawing 1 is that structure master of the present utility model looks generalized section, and accompanying drawing 2 is transverse cross-sectional view of accompanying drawing 1.Sequence number in the accompanying drawings is illustrated as: 1, tracheal intubation, 2, go up inflatable cuff, 3, inflatable cuff down, 4,8, gas tube, 5, cut off, 6,7, the gas outlet, 9, threeway, 10, air inlet pipe.

The specific embodiment

Below in conjunction with the embodiment that provides in the accompanying drawing, structure of the present utility model and use are elaborated.With reference to accompanying drawing, the two inflatable cuff endotracheal tubes of this kind, has endotracheal tube [1], last inflatable cuff [2] and following inflatable cuff [3] make it to form two chambeies up and down in cutting off [5], it is characterized in that having gas tube [4] and [8] on the endotracheal tube wall, the gas outlet [6] of gas tube [4] is in last inflatable cuff [2], in gas outlet [7] the infra inflatable cuff [3] of gas tube [8], the air inlet of gas tube [4] and [8] connects threeway [9], has an air inlet pipe [10] in threeway [9].In use, can pass through the handle of swivel tee [9], the intracavity of upper and lower sleeve capsule is inflated respectively or inflation simultaneously, like this, under the effect that cuts off [5], the pressure of upper and lower cavity can alternate, thereby can replace the pressure of mitigation on tracheal wall, like this can be in the use of tracheal intubation by increasing and reduce the gas pressure in the two-chamber sacculus, prevent that the phenomenon of ischemia from appearring being extruded in tracheal wall under single pressure effect, inflatable cuff is damaged the problem of tracheal wall in the time of can avoiding common endotracheal tube to use for a long time to the same lasting pressure of position generation of inner surface of trachea.

Claims

1. two inflatable cuff endotracheal tube, has endotracheal tube [1], last inflatable cuff [2] and following inflatable cuff [3], it is characterized in that on the endotracheal tube wall, having gas tube [4] and [8], the gas outlet [6] of gas tube [4] is in last inflatable cuff [2], in gas outlet [7] the infra inflatable cuff [3] of gas tube [8], the air inlet of gas tube [4] and [8] connects threeway [9], has an air inlet pipe [10] in threeway [9].
