The invention discloses an umbrella-shaped needle-stick-injury-preventing infusion port puncture needle set, and belongs to the technical field of medical instruments. The umbrella-shaped needle-stick-injury-preventing infusion port puncture needle set comprises an umbrella-shaped structural plate, a puncture needle and a connecting pipe, the puncture needle penetrates through the umbrella-shapedstructural plate, and the connecting pipe is perpendicularly and fixedly connected to the tail end of the puncture needle; and a plurality of frameworks are rotatably connected to the periphery of thepuncture needle through rotating shafts, protective films are bonded among the frameworks, and the frameworks and the protective films form a protective cover. The umbrella-shaped needle-stick-injury-preventing infusion port puncture needle set solves the problems that: puncture center position of an infusion port puncture device product used clinically at present is not accurate enough, the occurrence rate of needle stick injury is high, discomfort is brought to patients, and pain of the patients is increased. The set has the advantages that: the set can be easily held and punctured by medical staff, the puncture position is easy to control, meanwhile, the puncture device can be effectively fixed, and the comfort of the patients is improved.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to an umbrella-shaped puncture needle set for preventing needle stab wounds at an infusion port. Background technique [0002] The infusion port is a closed infusion device that is completely implanted in the human body, including the catheter part with the tip located in the superior vena cava and the injection seat implanted under the skin. System, which provides long-term venous access for patients. During the infusion period, the infusion port is replaced every 7 days without damaging the needle. If the tube is blocked, the diluted urokinase 5000u / ml, 0.5ml can be injected into the PICC tube by negative pressure technology After staying in the cavity for 15 to 20 minutes, draw back with a syringe. If blood is drawn out, it means that the thrombolysis is successful. [0003] There are some problems in the similar infusion port puncture devices currently used in clinical ...
