Described a kind of transfusion bottle stopper puncture needle, is characterized in that described inclined-plane ovalize.Both can guarantee the sharpness at needle tubing tip, and avoid again in the process of puncture rubber stopper, rubber grain comes off, and also can effectively reduce the resistance in piercing process simultaneously.
Described a kind of transfusion bottle stopper puncture needle, it is characterized in that this puncture needle also comprises air inlet needle tubing, air inlet needle stand, on the sidewall of described feed liquor needle tubing, be provided with inlet opening, air inlet needle tubing extend into feed liquor needle tubing inside, its lower end and air inlet needle stand are connected, air inlet needle stand is equipped with below feed liquor needle stand, on the sidewall of air inlet needle stand, is provided with air inlet.
Described a kind of transfusion bottle stopper puncture needle, is characterized in that the top of described air inlet needle tubing extend into the upper end of inlet opening.
Described a kind of transfusion bottle stopper puncture needle, is characterized in that described air inlet is vertically set on air inlet needle stand, and air inlet communicates with the bottom of air inlet needle tubing.
Described a kind of transfusion bottle stopper puncture needle, is characterized in that being provided with the connecting hole communicating with feed liquor needle tubing on described feed liquor needle stand, is provided with the input duct communicating with connecting hole in air inlet needle stand.
Described a kind of transfusion bottle stopper puncture needle, is characterized in that described feed liquor needle stand is a hollow plastic, and one end endoporus is for fixing feed liquor needle tubing, and other end endoporus is connected with feed liquor needle tubing the composition infusion channel that communicates, and cylindrical can connect with infusion tube.
Described a kind of transfusion bottle stopper puncture needle, is characterized in that the hollow plastic that described feed liquor needle stand endoporus is taper, and one end endoporus is for fixing feed liquor needle tubing, and other end endoporus arranges 6% taper fit syringe conehead and is connected and communicates with feed liquor needle tubing.
A kind of puncture needle of infusion bottle of this utility model, simple in structure, reasonable in design, by the tip portion design of feed liquor needle tubing is to an oval inclined-plane, reduce on the one hand production process, reduce production costs, can reduce on the other hand penetration Resistance, reduce the probability of rubber stopper particle detachment, avoid pin hole to stop up, the needle tubing tip portion of this kind of structural design simultaneously,, there is not dead band in easy to clean, uses more safe and reliable.

The specific embodiment
Below in conjunction with Figure of description, this utility model is described in further detail, and provides the specific embodiment.
As shown in figs. 1 and 4, a kind of transfusion bottle stopper puncture needle of this utility model, comprise feed liquor needle tubing 1, air inlet needle tubing 2, feed liquor needle stand 3, be equipped with the air inlet needle stand 4 below feed liquor needle stand 3, air inlet needle tubing 2 is equipped with on air inlet needle stand 4, its top extend into feed liquor needle tubing 1 inside, on the sidewall of feed liquor needle tubing 1, be provided with inlet opening 5, on the sidewall of air inlet needle stand 4, be vertically installed with air inlet 6, air inlet 6 communicates with the bottom of air inlet needle tubing 2, the top of air inlet needle tubing 2 extend into the upper end of inlet opening 5, on feed liquor needle stand 3, be provided with the connecting hole 8 communicating with feed liquor needle tubing 1, in air inlet needle stand 4, be provided with the input duct 9 communicating with connecting hole 8, the point of feed liquor needle tubing 1 is a level and smooth inclined-plane 7, the setting on inclined-plane 7, only need one grinding process to complete, can effectively reduce production costs, enhance productivity, these inclined-plane 7 ovalize designs, the design on oval inclined-plane has less resistance in the process of puncture rubber stopper, reduces the probability that rubber grain comes off simultaneously, avoids the obstruction of pin hole, reduces medical personnel's workload, , there is not the not dead band of easy cleaning in the position, feed liquor syringe tip end of this structural design simultaneously, clean more convenient, improve use safety.
