Description
Technical Field
The utility model relates to the technical field of medical auxiliary equipment, in particular to an anti-puncture transfusion harbor positioner.
Background
The implanted venous transfusion port is a completely implanted vascular channel system, and the tip is positioned on the catheter part of the superior vena cava and a medical apparatus embedded in a subcutaneous injection seat. It provides long-term venous vascular access to the patient, and the system includes a central venous catheter having a device called a puncture site attached to its distal end. The catheter can be placed in a great vein of a human body through subcutaneous puncture by an operation, such as an upper vena cava of a subclavian vein, part of the catheter is buried in subcutaneous tissue, a puncture seat at the other end is reserved in the subcutaneous tissue of a chest wall and is sutured and fixed, the appearance of skin after the operation only sees a small sutured wound, and the body surface of a patient can touch a protruding ball after healing and removing the suture. During treatment, the needle is positioned from the position, the needle is penetrated through skin and vertically enters the liquid storage tank of the puncture seat, so that the injection can be conveniently carried out, the continuous transfusion and blood sampling can be carried out for a long time, and the injection device is suitable for the transfusion of high-concentration chemotherapeutic drugs, complete parenteral nutrition and blood products. Because the tail end of the catheter is positioned in a great vein, the concentration of the medicine can be diluted rapidly, the stimulation and damage to the wall of the blood vessel are avoided, the probability of arteriosclerosis is reduced compared with the common intravenous transfusion, and the pain caused by repeated needle insertion of the blood vessel cannot be found is also reduced. The daily life of the patient is not limited after the infusion port is implanted, and the patient is convenient and relaxed to receive the medical treatment, thereby greatly improving the life quality. When the transfusion port is used, medical staff inserts the injection needle into the transfusion port transfusion device of a patient directly to achieve the work of injecting the liquid medicine, the problem that the injection needle is inclined or pricked frequently occurs to influence the use of the medicine input, the serious excessive force possibly pierces the transfusion port device body to cause the damage of the appliance to influence the use, and the skin of the patient is more seriously pierced to cause the damage to the body of the patient, so that stronger experience is required when the transfusion port transfusion work is carried out. The infusion port contact pin is a contact pin area pressed by adopting a two-finger or three-finger fixing method, has certain difficulty for nurses who operate for the first time or occasionally, and the contact pin area is blocked by fingers, so that the visual field is reduced and the fingers are easy to insert. According to statistics of the United states disease prevention and control center, 80-90% of the infectious diseases of healthy medical staff are caused by needle-stick injuries. Therefore, there is a need for a fixator that can effectively prevent medical personnel from being easily needled during the process of inserting needles, and that is easy to position to improve the success rate.
