Abstract

A bronchia sputum suction catheter is characterized in that the bronchia sputum suction catheter is formed by a catheter body (1) and a catheter head (2) which are integrally connected, wherein the axial included angle Alpha of the catheter body (1) and the catheter head (2) is smaller than 180 degrees, the catheter body (1) and the catheter head (2) are connected through smooth transition, and sputum suction holes (3) are formed at the lower end of the catheter body (1) and/or the catheter head (2). The protuberance damage caused by the insertion of the sputum suction catheter is fundamentally avoided, and the sputum suction catheter can be inserted more conveniently and smoothly; and the structure is simple and the manufacturing is convenient (only proper improvements of the original sputum suction catheter manufacturing process are needed).

Description

The bronchus sputum aspirator tube

Technical field

This utility model relates to a kind of medical supplies, and especially a kind of sputum aspirator tube specifically a kind ofly is used for the bronchus sputum aspirator tube that the rescue process is used.

Background technology

As everyone knows, the bronchus of human body has 23 grades, in main trachea and bronchus junction and bronchus and bronchus junction be formed with knuckle.Usually need tracheotomy be rescued for the critical patient clinically, in order to prevent that patient's sputum from getting into pulmonary and causing infection and emphysema to need in time and the sputum sucking-off in the bronchus, the sputum aspirator tube of using always at present is a straight flexible pipe; What at first touch in the insertion process is the knuckle position; And knuckle is a position that ten minutes is tender and lovely, be easy to because of rubbing hemorrhage, in case cause the knuckle position hemorrhage; To directly cause patient death, therefore must be very careful when intubate.But get into bronchus or when the one-level bronchus gets into the next stage bronchus, be difficult to avoid contacting of tube head and knuckle position from main trachea when sputum aspirator tube in the practical operation; Therefore it is congested usually can to occur the knuckle position at present clinically; Cause the uncomfortable present situation of patient; To this, still there is not good solution at present.

Summary of the invention

The purpose of this utility model is that easy the contact with the knuckle position causes its hyperemia even hemorrhage threat to life phenomenon that generation is arranged when getting into the break-in of patient's bronchus to existing sputum aspirator tube, designs a kind of knuckle of avoiding automatically and inserts the bronchus sputum aspirator tube in the bronchus.

The technical scheme of this utility model is:

A kind of bronchus sputum aspirator tube is characterized in that it was formed by whole linking to each other of pipe shaft and tube head, and the axis angle α of described pipe shaft and tube head spends and seamlessly transits less than 180 and links to each other, and on the lower end of described pipe shaft and/or tube head, is provided with sputum suction hole.

Described angle is 120 degree.

The quantity of described sputum suction hole is at least two, and its symmetry is opened on pipe shaft and the tube head.

Described sputum suction hole lays respectively on the smooth connection transition region of lower end and pipe shaft and tube head of pipe shaft.

The end that tube head does not link to each other with pipe shaft is sealed end or perforate end.

The beneficial effect of this utility model:

To the damage of knuckle, and make to insert and send more convenient and smooth when this utility model has fundamentally solved sputum aspirator tube and inserts.

This utility model is simple in structure, and is easily manufactured, only needs that original sputum aspirator tube manufacturing process is carried out suitable improvement and gets final product.

Description of drawings

Fig. 1 is the structural representation of this utility model.

Fig. 2 is that the sputum aspirator tube of this utility model gets into bronchial view from trachea.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment this utility model is further described.

As shown in Figure 1.

A kind of bronchus sputum aspirator tube; Injection molded by medical plastic cement; It was formed by 2 whole linking to each other of pipe shaft 1 and tube head, and the axis angle α of described pipe shaft 1 and tube head 2 spends and seamlessly transits less than 180 and links to each other, and on the lower end of described pipe shaft 1 and/or tube head 2, was provided with sputum suction hole 3.The angle of angle is the best with 120 degree during practical implementation, and the quantity of sputum suction hole 3 is generally two or more and best symmetry is opened on pipe shaft 1 and the tube head 2.When the quantity of sputum suction hole 3 is two; On lower end and the pipe shaft 1 that preferably lays respectively at pipe shaft 1 and the smooth connection transition region of tube head 2; As shown in Figure 1, according to the difference of Shooting Technique, the end that tube head 2 does not link to each other with pipe shaft 1 both can manufacture closed structure; Also can manufacture open-celled structure, also have the effect of sputum suction hole during perforate.

As shown in Figure 2, when the sputum aspirator tube of this utility model near knuckle the time, because anterior bending and naturally in the entering arm, can not touch knuckle position 4.

This utility model does not relate to all identical with the prior art prior art that maybe can adopt of part to be realized.

Claims

1. bronchus sputum aspirator tube; It is characterized in that it was formed by whole linking to each other of pipe shaft (1) and tube head (2); The axis angle α of described pipe shaft (1) and tube head (2) is less than 180 degree and seamlessly transit and link to each other, and on the lower end of described pipe shaft (1) and/or tube head (2), is provided with sputum suction hole (3).

2. bronchus sputum aspirator tube according to claim 1 is characterized in that described angle is 120 degree.

3. bronchus sputum aspirator tube according to claim 1 is characterized in that the quantity of described sputum suction hole (3) is at least two, and its symmetry is opened on pipe shaft (1) and the tube head (2).

4. according to claim 1 or 3 described bronchus sputum aspirator tubes, it is characterized in that on the smooth connection transition region of lower end and pipe shaft (1) that described sputum suction hole (3) lays respectively at pipe shaft (1) and tube head (2).
