Abstract

The utility model relates to an anti-articulating device for the oral endotracheal tube. On the basis of the traditional oral endotracheal tube, an anti-articulating supporting sleeve is sleeved on the external diameter at one end where the endotracheal tube is close to the respirator. The supporting pipe is formed by high quality hard plastics through the compression casting, which has the characteristics of the articulating resistance and low deformation; the volume of the supporting pipe is small, one end surface of the supporting pipe is made into arc shape, without burr and edge, and two symmetrical fixing lugs are cast at the other end of the supporting pipe. The utility model has the advantages that the operation is convenient, the fixation is reliable, and the secretion of the oral cavity is favorable to be aspirated, and the anti-articulating device is not easy to be contaminated by the sputum, the reliability and the safety of the clinical emergency treatment can be greatly improved, and the therapy effect and the quality to the patient are ensured.

Description

Oral trachea cannula is prevented engaging device

Technical field

It is joining through oral cavity assisted respiartion tracheal intubation with the respirator outlet that this utility model belongs to, and particularly relates to the anti-engaging device of a kind of oral trachea cannula.

Background technology

At present, known at home clinical in each section when cardio-pulmonary resuscitation, one of the most frequently used emergency measures, promptly the patient is strengthened assisted respiartion is vital to oral trachea cannula.Traditional oral trachea cannula is made up of air bag, tracheal intubation, air injection pipe interface and air injection pipe, its four structures that become integral type through plastics die casting, the small end awl circle of respirator interface tightly inserts among the interior circle of trachea one end thin film air bag of die casting on the external diameter of the tracheal intubation other end; Be fixed with an air injection pipe on the air injection pipe interface, air injection pipe and tracheal intubation are solidly fixed, and air injection pipe leads directly to air bag, and after the gas injection, the gas injection interface can be closed automatically.Because of adapting to the flexibility of human airway, tracheal intubation selects for use the suppleness of material better, and stiffness and strength is relatively poor, easily by the patients teeth interlock, causes the tracheal intubation obturation, thereby making to breathe interrupts, in case out in the cold, dangerous consequence may appear.In order to prevent above-mentioned unexpected the appearance, at present, in clinical rescue, behind the disposable needle tubing outsourcing adhesive plaster commonly used, fill in the other effect of playing support of oral trachea cannula, preventing patients teeth interlock tracheal intubation, and make its obturation.But its shortcoming is conspicuous: one, and fixing dissatisfied; Its two, the volume of needle tubing outsourcing adhesive plaster is bigger, blocking the oral cavity influences suction expectorant easily; Its three, adhesive plaster is polluted by sputum easily.

Summary of the invention

This utility model provides a kind of oral trachea cannula to prevent engaging device for solving the technical problem that exists in the known technology.

The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is:

A kind of oral trachea cannula is prevented engaging device, form by air bag, tracheal intubation, supporting sleeve, respirator interface, air injection pipe interface and air injection pipe, the small end awl circle of respirator interface tightly inserts among the interior circle of trachea one end thin film air bag of die casting on the external diameter of the tracheal intubation other end; On the air injection pipe interface, be fixed with an air injection pipe, air injection pipe and tracheal intubation are solidly fixed, air injection pipe leads directly to air bag, supporting sleeve of suit on the close respirator interface one end external diameter of tracheal intubation, one end face of supporting sleeve is in the arc-shaped, is cast with two symmetric fixedly ears on the other end of supporting sleeve.

Advantage and the good effect that the utlity model has are: this utility model supporting sleeve that anti-interlock of suit is used on the external diameter of traditional tracheal intubation one end, supporting sleeve forms with strength and stiffness hard plastic die casting preferably.One end face of supporting sleeve is made circular arc, do not have burr and corner angle, be cast with two symmetric fixedly ears at its other end.Substitute traditional disposable needle tubing outsourcing adhesive plaster with such supporting sleeve, being placed in oral trachea cannula plays a supporting role outward, not only can overcome the shortcoming or the deficiency of traditional oral trachea cannula fully, but also have following advantage: supporting sleeve is sleeved on the tracheal intubation external diameter, and is very convenient during use; The rigidity of supporting sleeve is better, after the patients teeth interlock occurring, can not make supporting sleeve that excessive distortion is arranged, and it is inaccessible that tracheal intubation is occurred, and interrupt assisted respiartion, the safety that jeopardizes patient; The outer end of supporting sleeve is cast with two symmetric fixedly ears, and available adhesive plaster is bonded in patient's face, and is fixing reliable; The external diameter of tracheal intubation is thinner, has reduced in patient's mouth taking up space, and helps the secretions of sucking-off intracavity; The supporting sleeve that rigid plastics is made is not easy to be polluted by sputum.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the side view of supporting sleeve among Fig. 1.

Among the figure: the 1-air bag; The 2-tracheal intubation; The 3-supporting sleeve; 3.1-fixing ear; 4-respirator interface; 5-air injection pipe interface; The 6-air injection pipe.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1 and Fig. 2, thin film air bag 1 of die casting on an end external diameter of tracheal intubation 2, on air injection pipe interface 5, fix an air injection pipe 6, air injection pipe and tracheal intubation 2 casting integrators, the straight-through again air bag 1 of air injection pipe 6 constitutes on the basis of traditional oral trachea cannula, again at the supporting sleeve 3 of tracheal intubation 2 near an anti-interlock of suit on the end external diameter of respirator interface 4.This supporting sleeve has the interlock of preventing, the little characteristic of distortion with hardness plastics casting forming preferably; The volume of supporting sleeve is little, one end face of supporting sleeve is made circular arc, there are not burr and corner angle, on the other end of supporting sleeve, be cast with two symmetric fixedly ears 3.1, easy to use, fixing reliable, help the intraoral secretions of sucking-off, also be not easy to be polluted, can improve reliability, safety and the assurance of rescue rescued effect and quality clinically greatly patient by sputum.

Claims

1. an oral trachea cannula is prevented engaging device, form by air bag, tracheal intubation, supporting sleeve, respirator interface, air injection pipe interface and air injection pipe, the small end awl circle of respirator interface tightly inserts among the interior circle of trachea one end thin film air bag of die casting on the external diameter of the tracheal intubation other end; On the air injection pipe interface, be fixed with an air injection pipe, air injection pipe and tracheal intubation are solidly fixed, air injection pipe leads directly to air bag, it is characterized in that: supporting sleeve of suit on the close respirator interface one end external diameter of tracheal intubation, one end face of supporting sleeve is in the arc-shaped, is cast with two symmetric fixedly ears on the other end of supporting sleeve.
