An adjustable size butterfly wing needle puncture protection kit for infusion ports

Abstract

The invention discloses a size-adjustable butterfly-wing needle puncture protection kit for an infusion port, specifically relates to the field of medical equipment, including a horizontal plate, vertical plates are arranged on both sides of the horizontal plate, and the vertical plate is in contact with the horizontal plate There are cavities on both sides of the horizontal plate, short rods are arranged inside the two cavities, one end of the short rod is fixed on one side of the horizontal plate, and the rear ends of the horizontal plate and the two vertical plates Both are provided with a fixing mechanism, and a positioning mechanism is provided between the two vertical plates, and the positioning mechanism is arranged on the top of the horizontal plate. The present invention wraps the patient's body by using two rubber belts, and at the same time uses a horizontal plate and a vertical plate to surround and fix the infusion port, so as to avoid hurting the hands during puncture, and the inner diameter of the rubber belt can be adjusted, so that the rubber belt can be wrapped On the bodies of patients of different sizes, in addition, the size of the area surrounded by the horizontal plate and the two vertical plates can be adjusted to fix infusion ports of different sizes, and has a wide range of applications.

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.
