Utility model content

In view of the deficiency of the prior art, the purpose of the utility model is to provide one kind to retain existing transfusion needle Has the anti-safety of acupuncture transfusion needle of Anti-stabbing function on the basis of function.

In order to achieve the above purposes, the technical solution adopted by the utility model is: anti-safety of acupuncture transfusion needle, including connection Seat, needle tubing, syringe needle and protective case are connected with needle tubing between syringe needle and attachment base, needle handle is additionally provided between needle tubing and syringe needle, protection Set is axially slidably set in outside syringe needle and needle tubing, and the length of protective case and needle length are adapted cooperation, and feature exists In offering rectangular perforation on needle handle, protective case is made using hard material and is provided in the axial direction on protection jacket wall The strip groove of width and the cooperation of needle handle thickness gap, the axial open end of strip groove are located at remote on syringe needle side, protective case The self-fastening button that cooperation is adapted with perforation rectangular on needle handle is equipped with from syringe needle one end.

Preferably, to be integrally formed or be bonded or the nested hand for being equipped with outwardly convex in a manner of these on above-mentioned protective case outer wall Shank.Facilitate promotion protective case.

Compared with prior art, the beneficial effect that the utility model has is: by needle handle using it is rectangular perforation, Design self-fastening button on the protective sleeve, when be infused complete after, by protective case slide into package needle position when, self-fastening button with it is rectangular Perforation coincide, and completes self-locking function, in the case where not increasing operator's complex operations can effective anti-needle thorn, also can be effectively controlled The secondary use of transfusion needle, the phase destroys also more convenient operation after using, while during production and transport, The problems such as needle tubing (capillary) discounting can be effectively prevent to flatten, occurs, more securely and reliably.

Detailed description of the invention

Fig. 3 is the utility model self-fastening button and the rectangular schematic diagram perforated and matched

Wherein, 1, attachment base, 2, needle tubing, 3, syringe needle, 4, needle handle, 4.1, rectangular perforation, 5, protective case, 5.1, strip groove, 5.2, self-fastening button, 5.3 handle portions.

Specific embodiment

Presently in connection with attached drawing, the utility model is further described.Obviously, therefore the utility model cannot be limited in Among the embodiment described range.Based on the embodiments of the present invention, those of ordinary skill in the art are not making wound Every other embodiment obtained under the premise of the property made is worked, all should belong to the protection range of the utility model.Following implementations Model, size, condition is not specified in example, conventionally, or selects according to product manual.

As shown in Figure 1-3, anti-safety of acupuncture transfusion needle, including attachment base 1, needle tubing 2, syringe needle 3 and protective case 5, syringe needle 3 with It is connected with needle tubing 2 in a manner of anchoring or glue sticking between attachment base 1, between needle tubing 2 and syringe needle 3 also in a manner of glue sticking It is fixed with needle handle 4, protective case 5 is axially slidably set in outside syringe needle 3 and needle tubing 2, and needle handle 4 is limited in protective case 5 and needle Between first 3, and the length of protective case 5 and 3 length of syringe needle are adapted cooperation, and 4 top of needle handle offers rectangular perforation 4.1, protection Set 5 is made and is provided in the axial direction between 4 thickness of width and needle handle on 5 wall of protective case using hard plastic or rubber material The strip groove 5.1 of gap cooperation, the axial open end of strip groove 5.1 are located on 3 side of syringe needle, protective case 5 far from syringe needle 3 one The self-fastening button 5.2 for adapting to cooperation with perforation phase 4.1 rectangular on needle handle 4 is equipped on end in a manner of anchoring or glue sticking, is being protected When sheath 5 slides into package syringe needle 3, self-fastening button 5.2 clasps rectangular perforation 4.1 to realize the self-locking of protective case 5.

To be integrally formed or be bonded or the nested handle portion 5.3 for being equipped with outwardly convex in a manner of these on 5 outer wall of protective case.Side Just protective case is pushed.

After infusion is completed, when protective case 5 is slid into package 3 position of syringe needle, self-fastening button 5.2 and rectangular perforation 4.1 Coincide, complete self-locking function, in the case where not increasing operator's complex operations can effective anti-needle thorn, also can be effectively controlled infusion The secondary use of needle, the phase destroys also more convenient operation after using, while during production and transport, can The problems such as effectivelying prevent needle tubing (capillary) discounting to flatten occurs, more securely and reliably.
