Detailed ways

The embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, but the utility model can be implemented in various ways defined and covered by the claims.

As shown in Figures 1 to 3, the utility model provides a multifunctional infusion set, which includes a dripping funnel 1, a liquid inlet pipe 2 arranged at the top of the dripping funnel 1, and a liquid outlet pipe 3 arranged at the bottom of the dropping funnel 1 After the extension of the end of the liquid inlet pipe 2, an exhaust conduit 4 is formed, and a bottle stopper piercer 5 is provided at the position where the exhaust conduit 4 and the liquid inlet pipe 2 are critical, and a side wall of the dropping funnel 1 is provided with The waterproof and breathable device is provided with an exhaust filter device on the liquid outlet pipe 3; wherein, the exhaust filter device of the present embodiment includes an annular pipe 6, which is connected with the liquid outlet pipe 3 at the symmetrical position of the annular pipe 6. At the same time, several vent holes 17 are also provided on the side wall of the annular pipe 6, and a waterproof and breathable film (not shown in the figure) is filled in the vent holes 17; the waterproof and breathable membrane of this embodiment The membrane can be made of polypropylene non-woven fabric; of course, the annular pipe 6 can be filled with a filter medium to make the filter device have a good filtering effect.

In this way, when using the infusion set, the bottle stopper 5 can be used to pierce the bottle stopper of the medicine bottle so as to connect the infusion set with the medicine bottle; The effect of air pressure will be generated, which will have a drainage effect on the medicinal liquid, and the medicinal liquid will enter the annular pipe 6 through the exhaust pipe 4, the liquid inlet pipe 2, the dripping funnel 1 and the liquid outlet pipe 3 under the action of gravity and air pressure inside, and then enter the human body through the filter medium and the liquid outlet pipe 3; it uses the exhaust conduit 4, the waterproof breathable device and the exhaust filter device to realize the three-time exhaust function of the entire infusion set, so that the gas in the infusion set can be completely exhausted, It enhances the effect of automatic feeding of the liquid medicine; and by closing the waterproof and ventilating device and controlling the function of the rubber thread, the function of automatic liquid stop can be achieved.
