Abstract

The utility model discloses a trachea cannula for preventing occlusion caused by teeth-clenching, which comprises a flexible pipe body, a hard pipe is sleeved on the outer side of the flexible pipe body and in a teeth-clenching region of a patient, and the hard pipe can slide on the flexible pipe body. As the hard pipe is sleeved on the outer side of the flexible pipe, the hard pipe is arranged in the tooth-biting region of the patient after the pipe body is inserted into the patient body, thereby effectively preventing the problem of the occlusion of the flexible pipe body caused by teeth-clenching during the treatment of the patient. The whole trachea cannula has the advantages of simple structure, convenience, practicality and low cost.

Description

A kind of anti-tracheal intubation of closing of stinging

Technical field

This utility model relates to a kind of flexible pipe for medical purpose, particularly a kind ofly is used to insert the endotracheal conduit of patient.

Background technology

At present in patient with severe symptoms's treatment, insert endotracheal tube through the oral cavity, it is the most frequently used artificial airway's the mode of setting up, for example known at home clinical in each section when cardio-pulmonary resuscitation, one of the most frequently used emergency measures, be about to air tube and insert in patient's trachea, the patient is strengthened assisted respiartion through the oral cavity.Because adapt to the flexibility of air flue in the human body, the intravital body of above-mentioned insertion patient select for use usually suppleness preferably material make, yet in actual use, after body being inserted in patient's body, because the phenomenon that tooth is tightly stung appears in patient easily in treatment, use the relatively poor body of rigidity easily by patient's dental articulation, cause the body obturation, cause and breathe to interrupt or liquid such as can't be input in patient's body at problem, thereby delay rescue time, if in a single day out in the cold, may cause very serious consequence.

The utility model content

Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of patient's tooth when treatment that can prevent tightly to sting the anti-tracheal intubation of closing of stinging that causes the body obturation.

The technical solution of the utility model is achieved in that a kind ofly anti-stings the tracheal intubation of closing, and comprises hose body, it is characterized in that: sting nested domain and be connected to hard tube at the hose body outside, patient's tooth.

Described in the utility modelly anti-sting the tracheal intubation of closing, its described hard tube can slide on hose body.

This utility model in the socket of the outside of flexible pipe one section hard tube, after body being inserted in patient's body, hard tube is arranged at patient's tooth and stings the zone, effective like this patient's tooth when treatment that prevented is tightly stung the problem that causes the hose body obturation, total is simple, and is convenient and practical, with low cost.

Description of drawings

Fig. 1 is a vertical cross section of the present utility model.

Labelling among the figure: 1 is hose body, and 2 is hard tube.

The specific embodiment

Below in conjunction with accompanying drawing, this utility model is done detailed explanation.

In order to make the purpose of this utility model, technical scheme and advantage clearer,, this utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation this utility model, and be not used in qualification this utility model.

As shown in Figure 1, a kind ofly anti-sting the tracheal intubation of closing, comprise hose body 1, sting nested domain at hose body 1 outside, patient's tooth and be connected to hard tube 2, described hard tube 2 can slide on hose body 1.

In use, hose body is inserted in patient's body, the hard tube section is adjusted in patient's tooth stings the zone, to patient treatment the time, make hose body remain unimpeded state like this, prevented that effectively patient's tooth tightly stings the phenomenon that causes the inaccessible influence treatment of flexible pipe.

The above only is preferred embodiment of the present utility model; not in order to restriction this utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.

Claims

1. prevent stinging the tracheal intubation of closing for one kind, comprise hose body (1), it is characterized in that: sting nested domain and be connected to hard tube (2) at hose body (1) outside, patient's tooth.

2. according to claim 1ly anti-sting the tracheal intubation of closing, it is characterized in that: described hard tube (2) can be gone up at hose body (1) and slide.
