Background

The fully implantable venous access device (TIVAD) is also called a venous transfusion port, which is the currently international first-choice in-vivo venous transfusion device implantable under the skin for a long time, is mainly used for patients needing long-term and repeated transfusion, is suitable for intravenous injection or continuous transfusion of chemotherapy drugs and parenteral nutrition, and can be used for almost all venous treatments such as antibiotics, blood products, common venous transfusion, blood sampling and the like. The venous transfusion port obviously improves the safety of the venous access and reduces the pain caused by repeated puncture. The venous transfusion port is completely arranged under the skin and can be reserved for a long time, no exposed part is arranged outside the body, the maintenance frequency of the catheter is reduced, and the infection rate of the local part and the whole body is low; the simple maintenance brings comfort and convenience to the patient, and the individual privacy of the patient is well protected. An infusion port passage is established and is completely embedded into a subcutaneous infusion device, so that the bathing, swimming and the like of a patient are not influenced, and the living quality of the patient is improved; the frequency of once a month maintenance reduces the frequency of patient trips to the hospital. The medical service efficiency is improved while the limb movement of the patient is not influenced and the privacy of the patient is protected. About 150000 ports are reported to be implanted annually in the united states, and this technology is emerging domestically and is gradually replacing PICC as the first choice for patients with moderate to long term infusion. Currently, 80% of the ports are used for cancer therapy, and up to 60% of the ports are used for breast cancer therapy, and other application groups are lung cancer, lymphoma, leukemia, ovarian cancer and colorectal cancer in turn.

In the process of carrying out puncture and transfusion of the venous transfusion port, as the venous transfusion port is a smooth device which is positioned under the skin, medical staff wears gloves and fixes the venous transfusion port by a left thumb and a forefinger, when holding a butterfly wing needle by the right hand, the position of the butterfly wing needle is easy to slip from the finger space, the puncture part of the butterfly wing needle is arranged in the middle of the venous transfusion port, the position deviation is easy to cause puncture failure, even the butterfly wing needle accidentally injures the fingers of an operator due to sudden position slip, the phenomenon also occurs in clinic, and before puncturing, the air in the butterfly wing needle needs to be evacuated, the air is prevented from entering the body to cause air embolism, the air evacuation method is to inject physiological saline into the butterfly wing needle through an injector, a syringe is always fixedly connected behind the butterfly wing needle during puncturing, the venous transfusion port is usually prevented at the chest, the chest is an inclined plane, the injector is easy to slip off to draw the butterfly wing needle, thereby affecting the puncture of the butterfly wing needle in front.
