Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field especially, relates to a jugular vein catheter fixing device. BACKGROUND

[0002] The jugular vein catheter is often used in plasma replacement, and the existing jugular vein catheter is in the form of one into two, that is, one end is a jugular vein cannula, and the other end is a arteriovenous double tube, a branch connector is used to connect the jugular vein cannula and the arteriovenous double tube, and a tube end connector is arranged on the arteriovenous double tube.

[0003] The clinical operation process at the present stage is as follows: after the jugular vein catheter cannula operation is completed, a transparent dressing is attached to the skin puncture point, and medical adhesive tape is attached to the tube body and the corresponding skin close to the transparent dressing. The jugular vein cannula and the branch connector have an interface, and the tube end connector also has a detachable interface, which is easy to breed bacteria, so sterile gauze needs to be wound at the corresponding position to reduce infection. After the sterile gauze is wound, the medical adhesive tape is wound for packaging, and after the operation is completed, the arteriovenous double tube is relatively thick and long, and two tube clamps are arranged on the arteriovenous double tube, so that the arteriovenous double tube is relatively heavy and easy to swing. In order to avoid the possibility of moving the tube inserted into the vein, the other parts of the jugular vein catheter that are not fixed need to be attached to the corresponding skin with adhesive tape. The clinical operation at the present stage has the following disadvantages: (1) the medical adhesive tape is wound after the sterile gauze is wound at each interface of the jugular vein catheter, and it is troublesome to remove the medical adhesive tape during plasma replacement, and the medical adhesive tape may be adhered to the tube body and cause the tube inserted into the vein to move; (2) the branch connector is directly attached to the corresponding skin with the medical adhesive tape, and the lower part of the branch connector is not attached to the skin. Since the force on this position is relatively large, the branch connector is easy to loosen after being used for a long time, which causes the tube inserted into the vein to move.

[0004] Therefore, it is necessary to design a jugular vein catheter fixing device to solve the above problems. UTILITY MODEL CONTENTS
