Abstract

The utility model relates to a disposable central venous catheter which is characterized by comprising a catheter body, a connecting seat, an extension pipe joint and extension pipes, wherein the catheter body comprises a main cavity and a side cavity which are respectively communicated with the extension pipes by the connecting seat so as to form a liquid channel; the extension pipes are respectively provided with a blood stopping buckle used for controlling the input and the stop of the liquid in the main cavity and the side cavity, and the extension pipes are respectively connected with the extension pipe joint. The disposable central venous catheter has the following advantages: when a smooth liquid channel needs to be built for rescuing critically ill patients, especially the patients with circulatory failure, the catheter is arranged in the subclavian vein and the jugular vein of the patient, on one hand, the right atrial pressure or the central venous pressure can be monitored so as to guide transfusion therapy, on the other hand, liquid, medicines and nutrient solution can be pumped in continuously, and are simultaneously transfused by utilizing two channels with different channel cavities, so that the central venous catheter is an indispensable intervention therapy catheter for rescuing the critically ill patients.

Description

Disposable use central venous catheter

Technical field

This utility model belongs to clinical medicine and uses the technique with the apparatus field, particularly relates to a kind of disposable use central venous catheter.

Background technology

At present, hospital rescues the critical patient and generally adopts great saphenous vein or high-order great saphenous vein otomy, its operation is slow and complicated, sometimes blood vessel is sunken when the serious circulatory failure of patient closes, it is still obstructed that superficial vein cuts the back liquid infusion, so not only have a strong impact on salvage success rate, increased many troubles to medical personnel simultaneously.

Summary of the invention

This utility model provides a kind of simple in structure, disposable use central venous catheter of being convenient to operate 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: disposable use central venous catheter, it is characterized in that: comprise body, Connection Block, extension pipe joint and extension pipe, described body comprises main chamber and side chamber, and described main chamber and side chamber are communicated with the extension pipe respectively by Connection Block and form fluid path; Be equipped with respectively on the extension pipe and be used to control the input of main chamber, side chamber liquid and the hemostasis button that stops, described extension pipe is connected with the extension pipe joint.

This utility model can also adopt following technical scheme:

The rounded cutting-edge structure of described body insertion end.

Described body is bordering on to insert on the distolateral cavity outer wall and is shaped on the side opening that is communicated with the side chamber.

Described body is bordering on the insertion end master cavity outer wall and is shaped on the side opening that is communicated with main chamber.

Advantage and the good effect that the utlity model has are: because this utility model adopts technique scheme, when rescuing the critical patient especially the circulatory failure patient must in time set up unobstructed fluid path, this conduit is inserted patient's subclavian vein or internal jugular vein, and one side can guard right atrial pressure or central venous pressure instructs infusion treatment; Sustainable again on the other hand pumping liquid, medicine and nutritional solution utilize two different duct chamber passages to carry out infusion simultaneously, and this venous duct is successfully to rescue the indispensable interventional therapy conduit of critical patient.
