The elastic bands can be used for auxiliary fixing, avoiding falling off during movement, and improving the reliability of use.

[0033] In an embodiment of the present application, the bottom of the infusion part 120 is provided with a fixing strip 123 arranged along the needle 110, and the top of the adhesive plate 200 is provided with a fixing rail 230 matched with the fixing strip 123. The infusion needle 100 can be taken off to complete the insertion into the skin, and then the adhesive plate 200 is connected with the infusion needle 100 to complete the fixation, which is convenient for operation.

[0034] The fixing strip 123 is a strip structure with a polygonal or circular cross section arranged in a convex manner, and the cross-sectional shape of the fixing rail 230 is consistent with that of the fixing strip 123, so that the fixing strip 123 can be inserted into the fixing rail 230 to be fixed. The upper surface of the fixing rail 230 is an open structure, which can make the fixing strip 123 completely connected with the infusion part 120, thereby improving the firmness.

[0035] In an embodiment of the present application, the end of the needle 110 is sunken to be a puncture part 111, and the sunken height is consistent with the thickness of the adhesive plate 200. The setting of the adhesive plate 200 to make the needle 110 be raised is avoided, which affects the normal infusion, and the comfort is improved.

[0036] In an embodiment of the present application, the infusion part 120 is fixed at an acute angle with the needle 110, and the end of the infusion part 120 raised is provided with an infusion port, and the end opposite to the infusion port is provided with an exhaust port arranged horizontally. The infusion part 120 raised is convenient for connecting with the infusion tube, and the hand can pinch the infusion part 120 during the connection process.

[0037] In an embodiment of the present application, the bottom of the adhesive layer is a plastic layer 220, one end of the plastic layer 220 is extended to be a pulling-out part 221, and the length of the pulling-out part 221 is greater than the length of the adhesive plate 200. The plastic layer 220 can protect the adhesive layer, and after the adhesive plate 200 is placed at the required position, the plastic layer 220 is pulled out through the pulling-out part 221 to complete the adhesion.

[0038] According to the present application, the effect of the high-comfort indwelling needle is that the needle is convenient to be fixed, the fixation effect is better, the adhesive plate is not only convenient to be adhered and fixed, but also has a large contact area with the skin, which greatly improves the safety and comfort of wearing.
