Description

Puncture locator for transfusion port

Technical Field

The utility model relates to a medical appliance, in particular to a puncture locator for an infusion port.

Background

An implanted venous access port is a fully implanted vascular access system that provides a long term venous blood access to a patient. The port atraumatic needle was replaced every 7 days during infusion. If the tube blockage phenomenon occurs, 5000u/ml and 0.5ml of diluted urokinase can be injected into a PICC (peripherally inserted central catheter) tube cavity by using a negative pressure technology, the diluted urokinase stays for 15-20 minutes and is pumped back by using an injector, and if blood is pumped out, successful thrombus fusion is indicated.

The transfusion port needs puncture location, and if no locator is provided, the puncture location is usually located by adopting the following method: the thumb, the index finger and the middle finger of the non-dominant hand are made into a triangle, the transfusion port is fixed, and the middle point of the three fingers is determined. The puncture septum is gently inserted vertically from the middle point of the transfusion port until reaching the bottom of the liquid storage tank.

In the prior art, patent publication No. CN204951843U discloses an implantable infusion port puncture locator, which comprises a transparent sheet having the same shape as the top surface of the injection seat of the implantable infusion port, the size of the transparent sheet is slightly larger than the top surface of the injection seat, and a hole is formed in the center of the transparent sheet, and the shape and size of the hole are the same as those of the puncture membrane on the top surface of the injection seat. When the implanted infusion port puncture locator (a puncture locator for short) is used for performing implanted infusion port puncture operation, an operator holds the edge of the puncture locator with the fingers of the left hand, finds a hypodermic injection seat of a patient by means of finger touch, confirms the edge of the top surface of the injection seat, enables the outer edge of the puncture locator to coincide with the outer edge of the top surface of the injection seat, and enables a hole in the center of the puncture locator to be aligned with a puncture diaphragm on the implanted infusion port, so that a part capable of inserting a needle is pointed out.
