Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
As shown in figures 1-15, a kind of needle head structure being applicable to venoclysis needle and vein blood taking needle, comprise plastic flexible pipe 1 and be arranged on the syringe needle 7 of plastic flexible pipe end, syringe needle 7 comprises needle point 6 and needle handle 4, the middle part of described plastic flexible pipe 1 is installed with self-destruction support 2, self-destruction support 2 forms the storage pin chamber 9 storing syringe needle; Syringe needle 7 with its tail end (namely, needle handle tail end 16) for basic point overturn and embed described storage pin chamber 9 time, the plastic flexible pipe of syringe needle tail end (namely, plastic flexible pipe 3 between syringe needle and self-destruction support) doubling close the infusion hole (as shown in Figure 3, the plastic flexible pipe doubling at needle handle tail end 16 place) of plastic flexible pipe; Storage pin intracavity is provided with and blocks described syringe needle and the catch 10 stoping it to exit, and when this design makes self-destruction of the present invention, can effectively prevent the medicinal liquid in syringe needle and plastic flexible pipe from trickling down.
The left side in described storage pin chamber is needle point groove 8, right side is needle handle groove 12; Described catch is arranged in needle point groove 12, described needle handle 4 and needle handle groove 12 two side interference fit, thus realizes the fixing of needle handle; The front end of needle handle is against on the step surface of needle handle groove, thus realizes tightening of the plastic flexible pipe between syringe needle and self-destruction support; Fin on described needle handle is single-blade or double-vane.
The top of described needle handle groove extends to form temporary tank 20 to the left, obliquely; The both sides cell wall of temporary tank 20 can hold needle handle front portion (as shown in figure 11) tightly, the plastic flexible pipe still doubling at needle handle tail end 16 place also keeps infusion hole to close, need point out, close as long as plastic flexible pipe can realize infusion hole for doubled state, plastic flexible pipe is tightened and is just improved sealing effect further.This design makes syringe needle temporarily can preserve in midway, makes it not by bacteriological infection, and can prevent liquid leakage when self-destruction.
The bottom of described self-destruction support is provided with the connecting portion passed for described plastic flexible pipe, and connecting portion is provided with through hole 15; Described plastic flexible pipe passes described through hole and is bonded as one with self-destruction support.In the present embodiment, the downside of connecting portion extends and forms Handheld Division.
The both sides of described self-destruction support right-hand member form is convenient to the prerotation vane 11 that syringe needle embeds storage pin chamber.It can prevent medical personnel from very not making syringe needle not aim at deflecting away from of causing of storage pin chamber 9.
The both sides up and down of described needle handle tail end are provided with inclined-plane 18, and the syringe needle tail end between upper and lower inclined-plane forms " one " font 17, and the similar of its structure and a word spiral shell tool end, when guaranteeing plastic flexible pipe doubling, more docile, sealing effect is better.
Described step surface 17 is inclined plane; The plastic flexible pipe degree of tautness < needle handle front end that needle handle front end is against inclined plane top is against basifacial plastic flexible pipe degree of tautness.It is darker that syringe needle embeds storage pin chamber, then the sealing effect of turnover place of plastic flexible pipe is better, more not easy-to-leak liquid.
Described step surface is provided with the tooth bar (not shown) preventing the slippage of needle handle front end, its can prevent syringe needle under the effect of plastic flexible pipe elastic force automatically on move the sealing effect caused and reduce.
Described needle handle is that colourless transparent plastic is made; Described self-destruction support is provided with the mark of mark needle point model, it, without the need to worrying mixing of color mother, improves safety; Corresponding, self-destruction support there are enough positions identify needle point model, have both avoided the female impact on medicinal liquid of color, do not affected label again.
After transfusion, adhesive tape two is peeled off and is still sticked on needle handle, gets final product self-destruction, and adhesive tape need not be peeled off minimizing sufferer with needle handle and pull out pin pain.
Need point out, medical personnel are often had to reflect following situation: existing syringe needle in use, hand-held needle handle carries out thrusting human body, needle point can produce and rock, this is owing to becoming 90 degree of right-angle structures between needle handle 4 and needle main body, make needle point thrust human body to handle 4 force, the power of handle can not well be passed to needle point main body;
For this situation, as Figure 16, shown in 17, the present invention has also deducted a percentage a kind of novel needle handle structure, namely, syringe needle forms the needle handle 41 of arc, the connecting portion of needle handle 41 Handheld Division and needle handle (namely, the position that needle handle and needle main body combine) when being linked to be straight line, the included angle A of this straight line (herein by this straight line called after needle handle line) and needle point centrage is that (this acute angle carries out value to acute angle usually between 30 degree to 70 degree, included angle A in figure is 60 degree), arcuate structure is in order to aesthetics design, its core is, by adjusting the angle of needle handle line and needle point centrage, the power that needle main body is subject to is more close to needle point centrage.
As shown in figure 18, the present invention has also deducted a percentage the syringe needle of arc needle handle structure of another kind of double-vane, that is, the left and right sides of syringe needle forms the needle handle 42,43 of arc respectively.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
