Embodiment

[0043] Such as Figure 4 As shown in the schematic diagram of the side hole needle tube of the disposable infusion needle of the present invention, a needle hole 2 is set on the side wall of the needle tube 1, and the needle does not have the problem of shedding chips when puncturing the injection part, thereby avoiding harm to the human body.

[0044] Figure 5 Shown is a schematic diagram of an embodiment of a disposable infusion needle provided with a limiting structure in the present invention. The disposable infusion needle is provided with a limiting structure that restricts the movement of the infusion needle relative to the injection part; The structure of contact or surface contact, in this embodiment, the limiting structure is a positioning plate 81 perpendicular to the longitudinal axis of the infusion needle and in surface contact with the injection part.

[0045] Such as Image 6 It is a schematic diagram of an embodiment of a disposable infusion needle provided...

Abstract

The invention discloses a disposable transfusion needle, which comprises a needle tube and a needle hole at its end, and at least one needle hole is arranged on the side wall of the needle tube. The disposable infusion needle is provided with a position-limiting structure that limits the movement of the infusion needle relative to its connection object, such as an injection piece; the position-limiting structure is a structure that has line contact or surface contact with the connection object. The side hole needle tube of the disposable infusion needle of the present invention can solve the problem of puncture debris falling. The movement limit device of the disposable infusion needle reduces the breaking force of the needle tube when the patient's limb moves or the infusion device moves, so that the needle tube will not break.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a disposable infusion needle. Background technique [0002] The needle tube of the intravenous infusion needle is a beveled needle, the needle tube is connected to the needle handle, and the needle seat at the rear end of the needle handle is connected to the catheter and the infusion set connection seat. . There are two main types of needle handles for intravenous infusion needles, single-wing and double-wing, such as figure 2 Both are shown. Mainly for the convenience of the nurse holding the needle for puncture, it is convenient to fix the intravenous infusion needle on the patient's limb after the puncture is successful. [0003] However, when infusion devices with injection parts such as indwelling needles or central venous catheters are used for clinical infusion, conventional intravenous infusion needles are usually used to connect with injection parts such as indwelling ...
