Abstract

A hemodialysis central venous catheter with an air bag relates to the field of medical tools and comprises a central venous catheter body, an extracting device and the air bag. The central venous catheter body is in cup joint with the extracting device closely, and the air bag is arranged on the central venous catheter body. When the air bag is swollen, the air bag can be used for fixing the catheter and simultaneously can seal a subcutaneous tunnel. Blood can not flow out, and when air in the air bag is drawn out, the hemodialysis central venous catheter can be pulled out. The hemodialysis central venous catheter is simple in operation and can not injure skin.

Description

The dark venous duct of a kind of hemodialysis with air bag

Technical field:

This utility model relates to the medical tool field, is specifically related to the dark venous duct of a kind of hemodialysis with air bag.

Background technology:

What existing hemodialysis mainly adopted with dark venous duct is to fat deposit by skin, again dark venous duct is inserted into dark vein, the medical needlework of general employing schedule skin with the conduit composite solid after inserting, prevent that conduit from deviating from blood vessel, make its skin injury easily like this, leave cicatrix, cause line to come off, in case the while misoperation is oozed out blood along tube wall easily.

The utility model content:

The purpose of this utility model provides the dark venous duct of a kind of hemodialysis with air bag, can play the effect of A/C during its airbag inflation, simultaneously the hypodermic tunnel of inlying catheter played sealing function, blood is flowed out, extract the interior gas of air bag out and can extract the dark venous duct of hemodialysis, it is simple to operate, can injured skin.

In order to solve the existing problem of background technology, this utility model is by the following technical solutions: it comprises dark venous duct 1, draw-out device 2 and air bag 3; Dark venous duct 1 and draw-out device 2 closely are socketed, and air bag 3 is arranged on the dark venous duct 1.

During this utility model operation dark venous duct 1 is inserted dark vein layer 6,3 in air bag is between skin layer 4 and fat deposit 5, during draw-out device 2 work, air bag 3 is inflated, air bag 3 will expand, air bag 3 will play the effect of A/C and sealing like this, prevent conduit deviate from blood vessel prevent simultaneously hemorrhage, also easily the operation.

Air bag of the present utility model plays A/C and sealing function in during hemodialysis, prevent that conduit from deviating from blood vessel and preventing simultaneously hemorrhagely, and it is simple to operate, can injured skin.

Description of drawings:

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

The specific embodiment:

With reference to Fig. 1, this implementation by the following technical solutions: it comprises dark venous duct 1, draw-out device 2 and air bag 3; Dark venous duct 1 and draw-out device 2 closely are socketed, and air bag 3 is arranged on the dark venous duct 1.

The air bag of this implementation plays A/C and sealing function in during hemodialysis, prevent that conduit from deviating from blood vessel and preventing simultaneously hemorrhagely, and it is simple to operate, can injured skin.

Claims

1. the dark venous duct of the hemodialysis with air bag is characterized in that it comprises dark venous duct (1), draw-out device (2) and air bag (3); The closely socket of dark venous duct (1) and draw-out device (2), air bag (3) is arranged on the dark venous duct (1).
