Size-adjustable infusion port butterfly wing needle puncture protection kit

Abstract

The invention discloses an infusion port butterfly wing needle puncture protection kit with the adjustable size. Specifically, the invention relates to the field of medical instruments, and the infusion port butterfly wing needle puncture protection kit comprises a transverse plate, vertical plates are arranged on the two sides of the transverse plate; wherein the vertical plates make contact withthe transverse plate, cavities are formed in the two sides of the transverse plate respectively, short rods are arranged in the two cavities respectively, one end of each short rod is fixedly arranged on one side of the transverse plate, fixing mechanisms are arranged at the rear end of the transverse plate and the rear ends of the two vertical plates respectively, a positioning mechanism is arranged between the two vertical plates, and the positioning mechanisms are arranged at the top of the transverse plate. According to the infusion port butterfly wing needle puncture protection kit, thebody of a patient is wrapped by the two rubber belts; meanwhile, the infusion port is surrounded and fixed by the transverse plate and the vertical plate; during puncture, hands are prevented from being stabbed, the surrounding inner diameter of the rubber belt can be adjusted, so that the rubber belt can surround the bodies of patients with different figures, in addition, the surrounding area between the transverse plate and the two vertical plates can be adjusted so as to fix infusion ports with different sizes, and the infusion port fixing device is wide in application range.

Description

technical field [0001] The embodiment of the present invention relates to the field of medical devices, in particular to an adjustable-sized butterfly wing needle puncture protection kit for 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. It can be used for a long time or intermittently. The needle is referred to as a butterfly-wing needle. The tip of the butterfly-wing needle is a specially designed slope. Because there is a turning point, the slope of the needle is longer than that of ordinary needles, and the small angle can avoid "core formation". The membrane can make the injection seat puncture several times up to 2000-3000 times, while ordinary hypodermic needles may cause puncture membrane damage. [0003] In clinical practice, when performing needle i...

[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. It can be used for a long time or intermittently. The needle is referred to as a butterfly-wing needle. The tip of the butterfly-wing needle is a specially designed slope. Because there is a turning point, the slope of the needle is longer than that of ordinary needles, and the small angle can avoid "core formation". The butterfly-wing needle is not easy to damage the puncture of the infusion port Membrane, which can make the injection seat puncture several times up to 2000-3000 times, while ordinary hypodermic needles may cause puncture membrane damage

[0003] In clinical practice, when performing needle injection on the infusion port, use the thumb, index finger and middle finger of the non-dominant hand to fix the surrounding area of ​​the injection port, and arch the infusion port. At the bottom of the liquid tank, this kind of finger is fixed for puncture and it is easy to pierce the hand of the person, and the safety is low. Therefore, an adjustable-sized butterfly wing needle puncture protection kit for the infusion port is required.
