Abstract

The invention discloses an implantable infusion port. The implantable infusion port comprises a port body, a liquid storage cavity formed in the port body, a connecting pipe used for fixing a catheterand the port body and an injection piece fixedly arranged on the port body, wherein the liquid storage cavity is provided with a first opening and a second opening; the minimum caliber of the first opening is larger than the maximum caliber of the second opening; the injection piece is fixed into the first opening; the catheter communicates with the second opening; and the first opening is obliquely formed. The implantable infusion port has the advantages that the overall height of the infusion port in the implantation part of a patient is reduced, the pulling force of the infusion port on the skin of the patient is reduced, and the pain and foreign body sensation of the patient are reduced; in cooperation with a linear type non-injury needle, medical staff can operate and use the implantable infusion port conveniently, the effective area utilization rate of a puncture window is increased, the operation complexity is reduced, and the occurrence rate of postoperative mechanical phlebitis is reduced; and the occurrence rate of avascular necrosis caused by postoperative skin tension deficiency is reduced.

Description

technical field [0001] The present invention relates to the technical field of medical articles, in particular, to an implanted infusion port and a method for using it. Background technique [0002] Implantable infusion ports are generally used in medical infusion, and are used in conjunction with non-invasive needles. Through the non-invasive needles and implanted infusion ports, medicinal liquid is injected into the patient's body to treat patients' diseases. The structure of the implanted infusion port is relatively general, and it is disclosed in US Patents US4723948, US4861341, US5281205, US9017300, and Chinese Patent CN105163795B. Its general structure is as follows figure 1 As shown, it includes an infusion port body 101 ; a liquid storage chamber 102 for containing medical active substances; The top of the infusion port body 101 is provided with an injection part 105 for puncturing with an atraumatic needle 106 and entering into the liquid storage cavity 102 . The ...
