CN203154516U - Tracheal catheter - Google Patents

Abstract

The utility model belongs to medical instruments, and particularly relates to a tracheal catheter. An air bag is fixed at the front end of the tracheal catheter, an inflation tubelet is fixed in the middle of the tracheal catheter and communicated with the air bag, scales in tessellation line directions are marked on the tracheal catheter, and an upper half wing and a lower half wing are arranged on an outer cylindrical surface of the tracheal catheter. The tracheal catheter is simple in structure, convenient to use, resistant to immersion and wetting of oral secretion and firm in fixation.

Description

A kind of endotracheal tube

Technical field

This utility model belongs to medical apparatus and instruments, particularly a kind of endotracheal tube.

Background technology

When cervical vertebra, lumbar vertebra, cranium brain posterior approach and burn need back bark fetching skin grafting, all need the patient ventricumbent position, carry out muscle relaxant anesthesia with endotracheal tube and could perform the operation down, patient's face down, endotracheal tube, mouth fill up and are in vacant state.Existing way is the face that is fixed on patient with adhesive plaster or operation mucosa.Owing to the outflow of patient's mouth juice can be soaked adhesive plaster or operation mucosa, endotracheal tube takes place easily to be taken off pipe or weigh down the pipe phenomenon, cause patient owing to anoxia and brain deficiency, in addition dead, and operation inconvenience, waste time and energy.

Summary of the invention

In order to overcome the shortcoming of prior art, this utility model provides a kind of endotracheal tube, and it is simple in structure, and is easy to use, is not afraid of the oral cavity separatory and soaks fixation.

The technical scheme in the invention for solving the technical problem is: the front end of airway fixedly has air bag, fixedly there is the inflation tubule at the middle part, the inflation tubule communicates with described air bag, and the scale of the line direction of being always or usually as specified on the airway has upper and lower half wing on the external cylindrical surface of described airway.

This utility model is simple in structure, and is easy to use, is not afraid of the oral cavity separatory and soaks fixation.

Description of drawings

Below in conjunction with drawings and Examples this utility model is further specified.

Fig. 1 is this utility model front view;

Fig. 2 is the A-A cutaway view among this utility model Fig. 1.

The specific embodiment

As shown in Figure 1, 2, the front end of airway 2 fixedly has air bag 1, and fixedly there is inflation tubule 3 at the middle part, and inflation tubule 3 communicates with described air bag 1, and the scale 6 of the line direction of being always or usually as specified on the airway 2 has upper and lower half wing 4,5 on the external cylindrical surface of described airway 2.

Described upper and lower half wing 4,5 and described airway 2 be one.

Described upper and lower half wing 4,5 and described airway 2 be adhesively fixed and be one.

Claims (3)

1. endotracheal tube, it is characterized in that: the front end of airway (2) fixedly has air bag (1), fixedly there is inflation tubule (3) at the middle part, inflation tubule (3) communicates with described air bag (1), the scale (6) of the line direction of being always or usually as specified on the airway (2) has upper and lower half wing (4,5) on the external cylindrical surface of described airway (2).

2. endotracheal tube according to claim 1 is characterized in that: described upper and lower half wing (4,5) is one with described airway (2).
