[0004] However, this "innovative structure of the butterfly needle safety needle cover" directly forms a "V"-shaped opening at the front end of the needle cover, so that the narrow slot is too wide, and the clamping slot The front end is designed with two inclined guide angles, so once the butterfly needle is pushed or vibrated by external force, it is easy to make the wings of the butterfly needle slide out from the narrow slot through the guidance of the inclined guide angle of the clamping groove, and the Make the needle protrude out of the needle cover, causing people to be injured by the needle and infected with the virus
[0005] Because the structure and spatial form of the traditional butterfly needle are too simple, it is not easy to innovate the safety needle cover on the basis of such a simple structure in the patent "Innovative Structure of Butterfly Needle Safety Needle Cover" announced above. It is even more difficult to make breakthroughs and innovations in the limited space of the commonly used butterfly needles

Embodiment Construction
[0023] First, please refer to Fig. 1, Fig. 2 and Fig. 3, the disposable butterfly needle safety needle cover of the present invention includes a butterfly needle 20 and a needle cover 10, wherein:
[0024] A butterfly needle 20 is mainly provided with a needle head 21. The front end of the needle head 21 is a tip inserted into the human body, and the rear end of the needle head 21 is an infusion tube 22 that can be connected to drips; and the two sides of the needle head 21 extend horizontally Out of a wing 23;
[0025] A needle cover 10 includes a cylindrical body with a hollow inner hole 11. One end of the needle cover 10 forms a front end 100 for the needle head 21 of the butterfly needle 20 to protrude. As shown in Figure 1, the rear end of the needle cover 10 The two side edges of 101 are respectively cut with straight sectional grooves 12 from the rear end 101 ends, as shown in Figure 1 and Figure 3, each straight sectional groove 12 communicates with the inner hole 11 o...

The safe needle sleeve for disposable butterfly needle is designed to protect the operator from being stabbed and infected. There is beside the needle sleeve one triangular clamping slot communicated with the guide slot of the needle sleeve, so that the used butterfly needle to be disposed will be withdrawn into the needle sleeve and the wings of the butterfly will be clamped into the clamping slot. Thus, the needle of the butterfly needle will not extend beyond the needle sleeve and the operator is protected against being stabbed and infected.
Description
technical field [0001] The invention relates to a safety needle cover for a disposable butterfly needle, in particular to a butterfly needle for dripping, which is safer to use and discard. Background technique [0002] According to the current design of medical butterfly needles, there are many structures, such as patent announcement No. 221556 "Innovative structure of butterfly needle safety needle cover" patent case is an example; the feature of this patent application is mainly provided with a hollow cylindrical needle cover , There is a slot on the needle cover, the front end of the slot is a "V"-shaped and slightly arc-shaped inlet, one or one thin straight slot is opened in the middle, and a slender rectangular clamping slot is opened at the end , the front end of the clamping groove is provided with two inclined guide angles, the butterfly needle is inserted into the safety needle cover, and the wings of the butterfly needle are braced and fixed in the clamping groov...
