Description

Venous transfusion port fixing device

Technical Field

The utility model relates to the field of medical equipment, concretely relates to venous transfusion harbor fixing device.

Background

The venous transfusion port is a vascular access system which is completely implanted into a human body and can be left for a long time, the current venous transfusion port generally comprises a port body and a transfusion catheter, the port body and the transfusion catheter are required to be implanted into the human body in advance before use, liquid medicine can be injected into the port body after a needle of a syringe penetrates into the port body, and then the liquid medicine can enter the human body along the transfusion catheter. When the venous transfusion port is adopted, the liquid medicine can be injected into the needle without penetrating through the blood vessel, so that the blood vessel can be prevented from being damaged greatly due to frequent puncture, and the venous transfusion port is more suitable for patients who need frequent injection.

When the venous transfusion port is used, the needle needs to penetrate through the port body, but after the needle is pulled out, in order to ensure that liquid medicine enters a human body from the transfusion catheter and cannot leak from a through hole formed by the needle on the port body, the port body needs to be made of a material with good elasticity such as medical silica gel, and after the needle is pulled out, the through hole formed by the needle is automatically closed. However, this results in a relatively high pressure between the port body and the needle under the spring force of the port body after the needle has penetrated the port body, requiring a relatively high force to withdraw the needle. When the needle head is pulled out, the medical staff still needs to press the harbor body by fingers to position the harbor body, when the needle head is pulled out, after the needle head is separated from the harbor body, the arm for pulling out the needle head can slide backwards for a large distance under the action of inertia, the elbow part of the medical staff is easy to collide with adjacent personnel or equipment, and therefore after the needle head is completely pulled out, the arm for holding the needle head by the medical staff still needs to exert force to enable the arm to stop sliding backwards in time.

However, in the actual operation process, the arm is easy to exert excessive force to cause the needle head to move to the side close to the harbor body again, and the other hand of the medical staff still keeps the state of pressing the harbor body, so the needle head is easy to stab the medical staff at the moment, the risk of cross infection is generated, and the health of the medical staff is not protected.
