Embodiment Construction

[0009] Such as figure 1 As shown, the intravenous injection needle of the present invention includes a needle tube 1, a needle base 2 and an infusion tube 3, the needle tube 1 is fixed on the front end of the needle base 2, and the infusion tube 3 is connected to the rear end of the needle base 2, and the needle base 2 A wing 4 is provided on the side of the needle tube 1, and a sheet structure perpendicular to the axis of the needle tube 1 is provided on the wing 4 to form a pinch piece 5. Wherein, the pinch piece 5 can be arranged on the middle part of the wing piece 4, and the section is T-shaped; or it can be arranged on the end of the wing piece 4, and the section is L-shaped. The size of the pinch sheet 5 is convenient for the thumb and forefinger to pinch, and it does not need to be too big. Such as figure 2 As shown, for the intravenous injection needle with fins 4 on both sides of the needle base 2, the pinch 5 can be set on the fins 4 on one or both sides, as fi...

Abstract

The invention relates to the field of a medical device, and particularly to an intravenous injection needle. The intravenous injection needle comprises a needle tube, a needle seat and a transfusion tube. The needle tube is fixed to the front end of the needle seat. The transfusion tube is connected with the back end of the needle seat. The side surface of the needle seat is provided with a fin. The intravenous injection needle is characterized in that the fin is provided with a sheet-shaped structure which is vertical to the axis of the needle tube, thereby forming a holding plate. Accordingto the intravenous injection needle, through arranging the sheet-shaped structure which is vertical to the axis of the needle tube for forming the holding plate, an in use, an operator can hold the intravenous injection needle through a thumb and an index finger for performing a puncture action, thereby according with ergonomics and realizing no easy fatigue.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an intravenous injection needle. Background technique [0002] Existing intravenous injection needles usually include a needle tube, a needle holder and an infusion tube. The needle tube is fixed on the front end of the needle holder, and the infusion tube is connected to the rear end of the needle holder. The side is provided with wings, and the plane of the wings is parallel to the axis of the needle tube. Medical personnel generally pinch the fins with their fingers to puncture during infusion, but since the plane of the fins is set parallel to the axis of the needle tube, the hand posture is very awkward, which is not conducive to operation and is prone to fatigue. Contents of the invention [0003] The object of the present invention is to provide an intravenous injection needle that is easy to operate and less prone to fatigue in order to overcome the deficiencies of the p...
