The invention has the beneficial effects as follows: the outer face of described rubber plug body is the curved surface caved inward, when syringe needle inserts rubber plug body, the concave curvature of outer face produces tangential force to syringe needle and guides syringe needle to slide to the central authorities of rubber plug body, effectively prevent syringe needle deflection from accidentally injuring finger, and then improve safety when infusing; The syringe needle of tube for transfusion is inserted rubber plug body along pipette axis, and after syringe needle is stable, the inside of syringe needle forms cylindrical column, and the outer wall of syringe needle and the inwall of pipette surround tubular fluid column, and tubular fluid column is communicated with bottle by imbibing hole; Because the liquid outlet level height of tube for transfusion is lower than imbibing hole, so when filling full liquid in pipette and syringe needle, pipette and syringe needle form siphon arrangement; Under siphonic effect, liquid continuous the sucking pipette from imbibing hole and enter tube for transfusion from syringe needle in infusion bottle; Particularly in the transfusion later stage, liquid concentrates in pipette, finally enters tube for transfusion completely.

Structure of the present invention is simple, convenient for production, effectively can prevent syringe needle deflection from accidentally injuring medical personnel, the more important thing is when inserting syringe needle, it can ensure that the liquid of infusing in phial is fully used, effectively put and end to waste, ensure the standard of dosage simultaneously, and then improve effect of curing the disease.

As preferably, the caliber of described pipette be the 2-3 of regular tube for transfusion caliber doubly, the length of pipette and the syringe needle of tube for transfusion isometric; After syringe needle to be inserted the central authorities of rubber plug body by tube for transfusion, described syringe needle enters described pipette along pipette axis, and the thickness of tubular fluid column that now pipette inwall and syringe needle outer wall surround is slightly less than tube for transfusion radius and described syringe needle and the distance at the bottom of pipette pipe are the thickness of bottle stopper; This size can make to form good siphon in pipette, and then promotes the ability that tube for transfusion draws residual liquid.

As preferably, the outer face of described rubber plug body is installed with the rubber suction cups of outward opening; Under naturalness, rubber suction cups caves inward, and this shape can guide syringe needle to insert the central authorities of rubber plug body, effectively prevents syringe needle deflection from accidentally injuring hands and refers to; Meanwhile, after syringe needle inserts rubber plug body, rubber suction cups firmly can adsorb the end of syringe needle, effectively prevents syringe needle from coming off.
