Detailed description of the invention
The technological means realized to make this utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth this utility model further.
Shown in Fig. 1-Fig. 4, the single use metal provided in figure and the blunt nosed pin of polypropylene, comprise and adopt metal material to make or adopt polypropylene material to make blunt nosed pin body, blunt nosed pin body comprises blunt nosed pin 100 and needle stand 200, blunt nosed pin 100 and needle stand 200 are formed in one, and further increase this blunt nosed needle construction stability.
Blunt nosed pin 100 comprises the blunt nosed pin in front end 110 and is connected to the blunt nosed pin 120 in rear end of blunt nosed pin 110 rear end, front end, liquid outlet channel 112 is offered in the blunt nosed pin 110 in front end, the front end of the blunt nosed pin 110 in front end is closed, when avoiding blunt nosed pin piercing vials, the chip of bottle stopper blocks blunt nosed pin, guarantee normal dosing, further increase the Practical Performance of this blunt nosed pin.
On the sidewall of the blunt nosed pin in front end 110, along front end, blunt nosed pin 110 axial direction evenly offers the liquid outlet 111 that several and liquid outlet channel 112 be connected, liquid outlet 111 is symmetricly set on liquid outlet channel 112 both sides, the medicinal liquid that the front end avoiding existing liquid outlet to be opened in blunt nosed pin is caused adds the shortcoming comparatively concentrated, and further increases the mixing homogeneity of medicinal liquid.
The rear end liquid outlet channel 122 be connected with front end liquid outlet channel 112 is offered in the blunt nosed pin 120 in rear end, the diameter of liquid outlet channel 122 is then held to be greater than the diameter of front end liquid outlet channel 112, and the defecator 121 be provided with in rear end liquid outlet channel 122 for filtering liquid medicine, the external diameter of defecator 121 is identical with rear end liquid outlet channel 122, prevent the microgranule in the medicinal liquid needing to add from joining in original medicinal liquid, avoid working the mischief to patient.
