Further, the design of detachable dropping funnel. Shown in Fig. 2 (a), dropping funnel is connected, controls the entrance of medicinal liquid by interface a, b, then is exported the next structure of c connection by one, carries out plus-minus infusion bottle by removable a interface and c interface. And multiple dismountable dropping funnel can be connected with each other, such as Fig. 2 (b), wherein a, c are connected with extraneous by pore, and b connects squeezing tube, thus satisfied with difference disease Man's Demands.
Further, the control action of buoyancy flexible pipe and dropping funnel. When starting most, the liquid level in dropping funnel constantly rises to desired height, now just connects other medicine bottles. Owing to the buoyancy of buoyancy flexible pipe is made buoyancy flexible pipe to come off downwards by liquid level, therefore, the medicinal liquid of other medicine bottles may not flow into dropping funnel. When the medicinal liquid that one of them interface of dropping funnel flows into is used up soon, buoyancy flexible pipe Automatic-falling. When the non-Automatic-falling of buoyancy flexible pipe, may utilize pressurizing unit extruding set on squeezing tube, thus producing pressure, buoyancy flexible pipe being come off. After buoyancy flexible pipe completely falls off, owing to buoyancy flexible pipe is very soft, cannot be upright when completely falling off, this just ensure that the medicinal liquid height in dropping funnel will not block delivery outlet when increasing after medicinal liquid flows out.
Further, the speed governing effect of flow regulator. Start most, for accelerating the outflow of A bottle liquid medicine, the first flow regulator, second flow speed actuator to be fully opened so that the first dropping funnel, the second dropping funnel liquid level reach desired height, thus decreasing the working time. And when be connected to B, C two after bottle liquid medicine, just scalable flow regulator is by medicinal liquid reduced velocity flow.
In the invention process, first infusion tube and the first bottle stopper puncture head and the first dropping funnel are connected, second infusion tube and the first dropping funnel and the second dropping funnel are connected, 3rd infusion tube and the second dropping funnel are connected, first squeezing tube and the second bottle stopper puncture head and the first dropping funnel are connected, second squeezing tube and the 3rd bottle stopper puncture head and the second dropping funnel are connected, first flow regulator is connected the first infusion tube and the second infusion tube respectively with second flow speed actuator, and the first buoyancy flexible pipe, the second buoyancy flexible pipe are connected with the first dropping funnel and the second dropping funnel respectively.
First, medical personnel are connected 1 with the medicine bottle A, B, the C that prepare, and 3,4 connect 9,10, A medicine bottles respectively connects with 7 11 again, is sequentially connected with 5,12,8,6,13 by 11, when the liquid level in 5,6 reaches desired height, will pass through 2,3 connection B, C. Wherein, 14,15 connect 9,10, medicinal liquid warp, 13 outputs.
Wherein, first A herb liquid flows into the first infusion tube, the first dropping funnel, the second infusion tube, the second dropping funnel, the 3rd infusion tube, is flowing into human vein through traditional infusion link. Wherein, utilize the first infusion tube and the second infusion tube diameter big, the feature that flow is big, and fully open the first flow regulator, second flow speed actuator, accelerate A herb liquid and make liquid level in the first dropping funnel, the second dropping funnel reach desired height. When the medicinal liquid in the first dropping funnel, the second dropping funnel reach a certain height, just the second bottle stopper puncture head and the 3rd bottle stopper puncture head are connected to infusion bottle B, infusion bottle C, now coutroi velocity actuator so that the medicinal liquid speed of outflow slows down.
Described first buoyancy flexible pipe, the second buoyancy flexible pipe block the first squeezing tube and the second squeezing tube, therefore, are starting most, A bottle liquid medicine flow out, and B, C two bottle liquid medicine be plugged.
Due to the buoyancy to the first buoyancy flexible pipe of the medicinal liquid in the first dropping funnel so that the first buoyancy flexible pipe floats on medicinal liquid face without coming off downwards. And when A bottle liquid medicine runs low, the first buoyancy flexible pipe just comes off downwards automatically. If now the first buoyancy flexible pipe does not come off downwards, it is possible to extrude the first squeezing tube, utilizing the pressure that water column produces that the first buoyancy flexible pipe is come off, B bottle liquid medicine just begins to flow out.
Wherein, owing to the buoyancy of the second buoyancy flexible pipe is made the second buoyancy flexible pipe block the outlet of the second infusion tube by the medicinal liquid in the second dropping funnel, but the first squeezing tube circulates, so B bottle liquid medicine flows out, C bottle liquid medicine is still plugged.
In like manner, when B bottle liquid medicine runs low, the second buoyancy flexible pipe comes off, and utilizes method either automatically or manually that C bottle liquid medicine is begun to flow out.
Described first buoyancy flexible pipe, the second buoyancy flexible pipe just cannot be upright after coming off, so after follow-up medicinal liquid instills the first dropping funnel, will not block outlet owing to medicinal liquid face rises.
When A bottle liquid medicine runs low, the first buoyancy flexible pipe comes off, and B bottle liquid medicine just begins to flow out.
Needed for meeting patient, making full use of dismountable dropping funnel, namely the second dropping funnel can have multiple, it is possible to deducts, and can interconnect between dropping funnel, can meet the different demands of patient.
Medicinal liquid finally all through the 3rd infusion tube, will pass through traditional infusion link, such as flow regulator, liquid medicine filter, intravenous needle, finally enter human vein, thus realizing the treatment to patient.
