In conjunction with Fig. 2, in the present embodiment, can connect on visual dropper [4] top more than 3 or 3 tube for transfusions [2], and according to infusion order by infusion order after the high liquid level (HLL) of infusion bottle [1] herb liquid lower than the preceding minimum level of infusion order, complete many bottles of automatic decanting transfusions successively, and without artificially nursing and change bottle.

In the present embodiment, also the every tube for transfusion [2] on visual dropper [4] top all can be increased to visual dropper [4], directly with tee tube or the above bifurcated pipe of three troubles, connect, and save original visual dropper [4].

In conjunction with Fig. 5, Fig. 3, Fig. 7, in the present embodiment, can by infusion order after infusion bottle [1] on tube for transfusion [2] be filled with air, further reduce infusion order after infusion bottle [1] in the pressure of medicinal liquid to bottom, increase front and back infusion bottles [1] are poor to bottom pressure, improve the reliability of transfusion successively, while being particluarly suitable for a plurality of infusion channel, infusion order is progressively partly arrived all emptying at rear tube for transfusion [2].Now for make order after tube for transfusion [2] in too much the entering visual dropper [4] and affect infusion safety of air, need on visual dropper [4] or top tube for transfusion, increase ventilative only liquid valve [6], only the installation of the lower end of liquid valve [6] can allow air free discharge and stop the ventilative of medicinal liquid outflow to stop liquid film or stop liquid valve [8], only the air-filtering membrane [7] (the visual concrete condition of air-filtering membrane [7] is saved) that can allow air free pass in and out is installed in the upper end of liquid valve [6], when the liquid level in visual dropper [4] stops liquid film [8] lower than breathing freely, air is discharged from ventilative only liquid film [8] automatically, when the liquid level in visual dropper [4] reaches the height of ventilative only liquid film [8], ventilative only liquid film [8] stops medicinal liquid to be discharged.Ventilative only liquid valve [6] the also floating valve shown in available Fig. 7 [9] repacking replaces, the lower end of floating valve [9] is communicated with visual dropper [4], upper end tube for transfusion [2] make exhaustor into and install can allow air free turnover air-filtering membrane and in valve body, protrude suitable length, in the valve body of middle part, float valve [10] being installed can be the port sealing of exhaustor with former tube for transfusion [2], liquid level in visual dropper [4] is during lower than predetermined altitude, float valve [10] declines, air can be discharged from exhaustor automatically, when the liquid level in visual dropper [4] reaches predetermined altitude, float valve [10] is close to the port of exhaustor and is sealed prevention fluid expulsion, the port of exhaustor is advisable with little and thin, to improve float valve [10], when buoyancy is maximum, the pressure of port is improved to sealing property, when floating valve [9] stretches into liquid level when darker, can be in the perforate of valve body top, make the gas energy free-flow in floating valve [9] and visual dropper [4], make floating valve [9] and the liquid level in visual dropper [4] can keep balance, guarantee that the liquid level in visual dropper is steady.

In the present embodiment, for stop medicinal liquid in the preceding infusion bottle of infusion order [1] or tube for transfusion [2] enter order after infusion bottle [1] or tube for transfusion [2] in, or stop when changing bottle medicinal liquid to overflow from tube for transfusion [2] and the set-up procedure herb liquid of infuse overflows Ke Ge branch tube for transfusion [2] and goes up installation and can stop check valve, check-valves or the non-return flap etc. of fluid reflux can only make the unidirectional fluid one-way control valve flowing downward of fluid from other tube for transfusion [2]; When infusion channel is when more than 3 or 3, it is upper or be suspended on infusion support that the fluid one-way control valve on Yi Jiangge branch tube for transfusion [2] is arranged on each branch's tube for transfusion [2] from high to low according to infusion order.Also available switch or clip are closed corresponding tube for transfusion [2] to stop medicinal liquid to flow backwards.

Embodiment 2: in conjunction with Fig. 6, Fig. 7, it is on the basis of embodiment 1 grade, tube for transfusion [2] on visual dropper [4] top above increases the top tube for transfusion shown in Fig. 7 to the projecting inward and inner floating valve [9] that has float valve [10], and by infusion order the tube for transfusion [2] more than rear visual dropper [4] to be full of air emptying, and emptying height is advisable to be greater than the preceding infusion bottle herb liquid of order height.During transfusion, first a tube for transfusion [2] is inserted in the preceding infusion bottle of infusion order [1] air in this tube for transfusion [2] is drained, and make infusion order after tube for transfusion [2] floating valve [9] straight up, in evacuation procedure, when the preceding infusion bottle of infusion order [1] herb liquid arrives the bifurcation of tube for transfusion [2] by start to infusion order after tube for transfusion [2] in flow, after pressure balance or in wait infusion process, the preceding infusion bottle of infusion order [1] herb liquid by continue to infusion order after tube for transfusion [2] on floating valve [9] in flow, and float valve [10] is constantly upwards floated until protrude tube for transfusion [2] close contact of valve body and make this tube for transfusion [2] sealing with top, make the fluid in valve body [9] can not upwards discharge and stop emptying process, make infusion order after tube for transfusion [2] floating valve [9] more than tube for transfusion be all that emptying state does not have medicinal liquid, when infusion order after tube for transfusion [2] insert infusion order after infusion bottle [1] time, because of infusion order after tube for transfusion [2] be emptying state, infusion order after infusion bottle [1] herb liquid to below tube for transfusion [2] particularly the pressure of float valve [10] be less than the pressure of the preceding infusion bottle of infusion order [1] herb liquid to below tube for transfusion [2], add floating valve [9] by infusion order after tube for transfusion [2] shutoff, when therefore the medicinal liquid in the preceding infusion bottle of infusion order [1] is not totally lost, infusion order after infusion bottle [1] in medicinal liquid because of pressure difference, can not enter infusion order after tube for transfusion [2], when the preceding infusion bottle of infusion order [1] herb liquid be totally lost and tube for transfusion [2] in liquid level drop to certain position (generally lower than infusion order after tube for transfusion [2] buoyancy valve [9] in medicinal liquid) time, infusion order after tube for transfusion [2] buoyancy valve [9] in medicinal liquid start to flow downward and reduce the liquid level in this floating valve [9], float valve [10] is also opened infusion channel along with decline, infusion order after infusion bottle [1] in the effect of medicinal liquid at self pressure under enter infusion order after tube for transfusion [2] in automatic decanting and continue transfusion, now due to infusion order after infusion bottle [1] pressure of below has been greater than to the pressure in the preceding tube for transfusion of infusion order [2], add that the preceding floating valve of infusion order [9] is emptying with upper tubing [2], infusion order after tube for transfusion [2] in medicinal liquid start to infusion order in preceding tube for transfusion [2] to flow, and the preceding float valve of infusion order [10] is constantly upwards floated until protrude tube for transfusion [2] close contact of valve body and make this tube for transfusion [2] sealing with top, make the fluid in valve body [9] can not upwards discharge and stop emptying process, making the above tube for transfusion of the preceding tube for transfusion of infusion order [2] floating valve [9] is all that emptying state does not have medicinal liquid, can enter again next round transfusion state successively continuously, and can carry out the automatic decanting work of a plurality of samsaras and need not wait for when medicinal liquid in last infusion bottle [1] is totally lost by manually changing bottle work, greatly reduce operating pressure and the workload of health care worker, it does not have strict requirement to the suspension height of each infusion bottle [1] simultaneously, can make each infusion bottle [1] be suspended on sustained height, while making to change bottle without the height of adjusting each infusion bottle [1], reduce workload and the operating pressure of health care worker, also reduced the requirement to infusion bottle [1] suspension holdfast.

In order to improve the sealing property of floating valve [9], the bore of the tube for transfusion that in valve body, protrude top is advisable with thin with little and smooth, tube wall, make float valve [10] when suffered buoyancy reaches maximum, make float valve [10] enough improve greatly sealing property to the pressure of the tube for transfusion bore of top protrusion.Float valve [10] is all advisable greatly with similar cylindrical and aspect ratio diameter to the profile of floating valve [9], makes the direction of float valve [10] in the process of fluctuating stable; The available hollow cylinder of float valve [10] and rubber or plastic sheeting sealing pressing gas are made, also available light foam material or sealed at both ends hollow cylinder are made main body, at upper surface, with elastic materials such as rubber or plastic sheeting parcel sponges, make, make the upper surface of float valve [10] soft and flexible, make float valve [10] can seal preferably the tube for transfusion bore that protrude top; The feeler that surrounding should be processed quantity and size is suitable, frictional resistance is little or the fulcrum of float valve [10], reduce the frictional force of float valve [10] and valve wall, the sensitivity that improves floating valve [9] to reduce float valve [10] with the contact area of floating valve [9] valve wall; Also float valve [10] can be made by rubber or the spherical sponge of plastic sheeting sealed envelope or spherical elasticity lightweight object; Simultaneously the volume of float valve [10] be greater than or approach the tube for transfusion internal diameter that in infusion bottle [1], liquid level and floating valve [9] top protrude long-pending and float valve sole mass be advisable, make float valve [10] only under the effect of buoyancy, just can seal infusion channel, guarantee that automatic decanting order is reliable successively.Now the lower surface of float valve [10] or floating valve [9] is advisable with uneven, and when the middle liquid level of floating valve [9] is declined, float valve [10] can not affect transfusion process by liquid outlet sealing.Floating valve [9] also available other suitable valve body replaces.

In conjunction with Fig. 9, in the present embodiment, equally also can connect by the tube for transfusion [2] with more than 3 or 3 band floating valves [9] on visual dropper [4] top, and according to infusion order by infusion order after the installation of floating valve [9] or suspension height lower than the installation of the preceding floating valve of infusion order [9] or suspension height (, installation or the suspension height of the floating valve of infusion order first [9] can freely be selected), when the medicinal liquid of an infusion channel be wherein totally lost or the floating valve [9] of this infusion channel in liquid level while dropping to certain position, liquid level in preceding each tube for transfusion of infusion order [2] all starts to decline, and entered in the preceding tube for transfusion of infusion order [2] without medicinal liquid in preceding each infusion bottle of infusion order [1], continue to infuse, liquid level in preceding each tube for transfusion of order [2] continues to decline, until order immediately after tube for transfusion [2] buoyancy valve [9] in liquid level decline and open this infusion channel, infusion order immediately after infusion bottle [1] in the effect of medicinal liquid at self pressure under enter infusion order immediately after tube for transfusion [2] in automatic decanting and continue transfusion, now due to infusion order immediately after infusion bottle [1] pressure of below has been greater than to the pressure in preceding each tube for transfusion of infusion order [2], add preceding each floating valve of infusion order [9] and emptying with upper tubing [2], infusion order immediately after tube for transfusion [2] in medicinal liquid start to infusion order in preceding each tube for transfusion [2] to flow, and preceding each float valve of infusion order [10] is constantly upwards floated until protrude tube for transfusion [2] close contact of valve body and make this tube for transfusion [2] sealing with top, make the fluid in each valve body [9] can not upwards discharge and stop emptying process, making the above tube for transfusion of preceding each tube for transfusion of infusion order [2] floating valve [9] is all that emptying state does not have medicinal liquid, when entering transfusion state, last infusion bottle [1] can enter again next round transfusion state successively continuously, and can carry out the automatic decanting work of a plurality of samsaras and need not wait for when medicinal liquid in last infusion bottle [1] is totally lost by manually changing bottle work, greatly reduce operating pressure and the workload of health care worker.

In the present embodiment, when infusion channel is when more than 3 or 3, in order to reduce sealing property difference to floating valve [9] inner liquid medicine loading difference because of floating valve [9], do not cause the suffered buoyancy of float valve [10] not etc., and it is chaotic that infusion order is occurred, can by infusion order after tube for transfusion [2] buoyancy valve [9] in the ratio infusion order of volume processing of float valve [10] preceding large, make infusion order after the suffered buoyancy of float valve [10] preceding larger than infusion order, the time of opening infusion channel is more late, makes to change bottle order and more stablizes with reliable.

In conjunction with Figure 11, in the present embodiment, when infusion channel is when more than 3 or 3, also the above floating valve [9] of 2 or 2 can be processed into sealing does not highly wait but middle and lower part or bottom by passage [12] the part or all of disjunctor floating valve [9] of connection each other, stepped shown in Figure 11 both can be processed in the bottom of disjunctor floating valve [9], also can be processed into flat or ramped shaped; But each float valve [10] must just differ with the contact of the tube for transfusion of top protrusion and difference in height distance is the bigger the better, make to only have infusion order all open and continue after transfusion without medicinal liquid at front floating valve [9], order after floating valve [9] just can open and continue transfusion, guarantee that infusion order is reliable and stable.The bottom of each floating valve [9] also can pick out separately tube for transfusion with reduce medicinal liquid flow on order after float valve [10] impact and upset infusion order.

In conjunction with Fig. 8, Fig. 4, in the present embodiment, in the medicinal liquid of the preceding infusion bottle of infusion order [1] is totally lost tube for transfusion [2] in liquid level decline process, for make infusion order after infusion channel can enter as early as possible transfusion state, floating valve shown in Fig. 7 [9] below tube for transfusion can be protruded to valve inner, the tube for transfusion protruding is also advisable with thin with little, tube wall with bore, make float valve [10] little to a certain extent time at suffered buoyancy, float valve [10] under the effect of gravity to below the enough large and raising sealing property of pressure of the tube for transfusion bore that protrudes; The lower surface of float valve [10] is also advisable so that softness is flexible simultaneously, makes float valve [10] can better seal the tube for transfusion bore that protrude below, floating valve [9] is processed into the mobile two-way fluid buoyancy control valve of energy bidirectional control flow body, as shown in Figure 8.When the liquid level of being totally lost in floating valve [9] when the medicinal liquid of the preceding infusion bottle of infusion order [1] drops to a certain degree, float valve [10] under the effect of gravity by below the tube for transfusion sealing of protruding stop medicinal liquid to continue to flow downward and pipeline below making produces negative pressure, under the effect of pipe negative pressure infusion order after infusion bottle [1] in medicinal liquid just can flow into rapidly tube for transfusion [2] and enter transfusion state, improve efficiency and the reliability change bottle.The very stable deviation of direction fluctuating when float valve [10] hour, float valve [10] upper and lower surface can be processed into and can coincide and the complete hermetic wedge shape of energy or other suitable shape with the tube for transfusion bore protruding, now tube for transfusion can be not projecting inward to valve body yet; Or when float valve [10] self can fit like a glove with valve body upper and lower surface and seal, also can make tube for transfusion not projecting inward to valve body.Now need float valve [10] enough large with the space (being the distance that float valve [10] fluctuates) of the tube for transfusion protruding up and down, in order to avoid the tube for transfusion that float valve [10] easily protrudes below shutoff in normal infusion sinking process and affect transfusion process.The only liquid valve [11] that now only the replaceable one-tenth of air-filtering membrane [7] top of liquid valve [6] top is filled with water, the gas of only being permitted to stop in liquid valve [6] is discharged from stopping liquid valve [11], and stop air from liquid valve [11] only only enters liquid valve [6], while making to change bottle, ducted negative pressure keeps stable and improves the stability of changing bottle, as shown in Figure 4; Only liquid valve [11] also available check valve, check-valves or the non-return flap etc. of fluid reflux of stoping can only make the valve body of one-directional fluid flow replace; The now only also replacement of floating valve shown in available Fig. 8 of liquid valve [6].Disjunctor floating valve [9] the below tube for transfusion that equally also bottom can be picked out separately to tube for transfusion is all processed into disjunctor two-way fluid buoyancy control valve to valve inner protrusion.Two-way fluid buoyancy control valve is available check valve (, check-valves or non-return flap etc.) and the combination valve replacement that can automatically the control valves for fluids such as floating valve of infusion channel or inlet sealing be formed when infusion bottle [1] herb liquid is totally lost also.

In the present embodiment, when infusion bottle [1] negligible amounts only needs a samsara, just can complete when transfusion, infusion order can be come to first floating valve [9] and save and reduce production costs.

In the present embodiment, when the length of each floating valve [9] enough large, the scope that fluctuates of float valve [10] is larger can play the same visual effect of visual dropper [4] time, original visual dropper [4] can be saved and saves production cost, now the volume of tube for transfusion more than floating valve [9] should be less than the amount that can deposit medicinal liquid in floating valve [9].

Embodiment 3: in conjunction with Figure 13, Figure 12, Figure 15, it is on the basis of embodiment 1, example 2, the above all tube for transfusions [2] of visual dropper [4] are directly connected with visual dropper [4], for stop in the changing bottle process preceding medicinal liquid of infusion order by infusion order after tube for transfusion [2] and the Bas Discharged in visual dropper [4] affect visual effect, can only make the downward one-way flow of fluid and stop the check valve that fluid flows backwards (, check-valves or non-return flap etc.) [21] in the upper installation of each tube for transfusion [2] (different height); And the ∩ type feed tube that turns back again downward after tube for transfusion [2] the syringe needle feed tube opening that inserts infusion bottle [1] is directly upwards made into first upwards, and buoyancy control valve [13] is installed at pin mouth place, as shown in figure 12; The structure of buoyancy control valve [13] by being fixed on fulcrum [16] on syringe needle, be movably arranged on fulcrum [16] upper and have soft and resilient can needle seal mouth sealing lever [17], raise the nose above water to breathe [15] form, as shown in figure 15.During transfusion, due to check valve [21] being installed on tube for transfusion [2], after the preceding tube for transfusion of infusion order [2] inserts in infusion bottle [1], although rotating the sealed end that seals lever [17] under the effect of buoyancy, opens floating head [15] infusion channel, but because the syringe needle ∩ type infusion channel after-opening that turns back is downwards downward, medicinal liquid in infusion bottle [1] need first overcome surface tension and upwards be pressed into syringe needle feed tube again, under normal pressure in medicinal liquid tube for transfusion more difficult to get access [2], health care worker need make the first liquid-transport pipe-line generation negative pressure that medicinal liquid is sucked or increasing the first infusion bottle internal pressure is pressed into medicinal liquid in tube for transfusion [2], check valve [21] on this tube for transfusion [2] is opened simultaneously, medicinal liquid enters visual dropper [4] and produces after certain pressure intensity, infusion order after tube for transfusion [2] on the effect of check valve [21] pressure in visual dropper [4] under close, stop air from infusion order tube for transfusion [2] in discharge, guarantee the visual effect of visual dropper [4], if buoyancy control valve [13] is vacant and when upwards sealing property better can stop air in this tube for transfusion [2] to be discharged by the preceding medicinal liquid of infusion order during vertical display, the check valve [21] on each tube for transfusion [2] can be saved, infusion order after tube for transfusion [2] do not insert infusion bottle in or while changing bottle with switch, clip etc. by infusion order after tube for transfusion [2] close the air stoping in this tube for transfusion [2] and discharged by the preceding medicinal liquid of infusion order, until infusion order after tube for transfusion [2] insert infusion bottle in and be inverted after open again switch or clip etc., and save the check valve [21] on each tube for transfusion [2].When infusion order after tube for transfusion [2] at the preceding infusion bottle herb liquid of infusion order, be not totally lost and insert infusion order in rear infusion bottle [1] time, although rotating the sealed end that seals lever [17] under the effect of buoyancy, opens floating head [15] infusion channel, but due to syringe needle ∩ type infusion channel, Open Side Down, more difficultly under medicinal liquid normal pressure in infusion bottle [1] overcome surface tension and enter in tube for transfusion [2], add in upper tubing [2] and be full of atmospheric air, infusion order after infusion bottle [1] in medicinal liquid the pressure of visual dropper [4] is significantly less than to medicinal liquid in the preceding infusion bottle of infusion order [1] pressure to visual dropper [4], infusion order after infusion bottle [1] in medicinal liquid cannot open buttoned-up check valve [21], infusion order after infusion bottle [1] in medicinal liquid can not enter in tube for transfusion [2], when the medicinal liquid in the preceding infusion bottle of infusion order [1] is totally lost, the sealed end that floating head [15] sinks will seal lever [17] because of the effect of gravity upwards rotates and seals infusion channel, now infusion channel starts to produce negative pressure and continues to increase, until by infusion order after infusion bottle in medicinal liquid continue transfusion in sucking tube for transfusion [2], complete automatic decanting work, and enter continuously transfusion state and can carry out the automatic decanting work of a plurality of samsaras and need not wait for when medicinal liquid in last infusion bottle [1] is totally lost by manually changing bottle work successively of next round, greatly reduce operating pressure and the workload of health care worker, it does not have strict requirement to the suspension height of each infusion bottle [1] simultaneously, can make each infusion bottle [1] be suspended on sustained height, while making to change bottle without the height of adjusting each infusion bottle [1], reduce workload and the operating pressure of health care worker, also reduced the requirement to infusion bottle [1] suspension holdfast.

In the present embodiment, also the syringe needle ∩ type infusion channel that Open Side Down upwards can be turned back opening is still made progress again, and infusion channel can directly be opened or seal to the floating head [15] that makes buoyancy control valve [13] under the effect of buoyancy, without controlling by sealing lever [17], or can, automatically by the suitable control valves for fluids such as floating valve of infusion channel or inlet sealing, make syringe needle seal valve structure simpler when being arranged on infusion bottle [1] herb liquid being totally lost on syringe needle or tube for transfusion.

In conjunction with Figure 10, in the present embodiment, for make infusion order after infusion bottle [1] in normal pressure medicinal liquid after inversion, because the effect of self gravitation produces, compared with normal pressure, large pressure forces medicinal liquid to enter in tube for transfusion [2], extraction valve shown in available Figure 10 by infusion order after infusion bottle [1] be inverted again to offset after being first pumped into certain negative pressure be inverted after medicinal liquid because of the pressure that action of gravity increases, when the preceding infusion bottle herb liquid of infusion order is not totally lost infusion order after infusion bottle [1] in medicinal liquid guarantee that infusion order is reliable and stable in can not entering tube for transfusion [2].Extraction valve by the hollow valve body [26] of being advisable with hard materials such as metal, plastics, air exhaust nozzle [23], air extracting seal plate or the chip module [25] that can dock with the breather of tube for transfusion [2], in addition set screw exhaustor [27], handle [22], regulate single capacity adjusting nut [28], the spring of bleeding [24], be arranged on front and back check valve on air exhaust nozzle [23] and exhaustor [27] (, check-valves or non-return flap etc.) [21] and form.While bleeding, first use handle [22] by exhaustor [27] and air extracting seal plate or chip module [25] inwardly by spring [24] compression, the check valve [21] on air exhaust nozzle [23] is closed, the check valve [21] on exhaustor [27] is opened, the Bas Discharged in valve body [26]; When release handle [22], the check valve [21] on air exhaust nozzle [23] is opened, and the check valve [21] on exhaustor [27] is closed, and extraction valve is extracted the air in infusion bottle [1] out; Adjust the position of adjusting nut [28] with regard to the each rate of air sucked in required of capable of regulating extraction valve, the visual concrete condition of adjusting nut [28] is saved.After equally also can directly infusion bottle [1] being pumped into negative pressure with syringe or other suitable instrument of bleeding, again infusion bottle [1] is inverted.

In conjunction with Figure 16, in the present embodiment, can make the buoyancy control valve [13] of the syringe needle opening part of tube for transfusion [2] into the floating valve shown in Figure 16 [19], and control position is also moved on to the upwards highest position of part of syringe needle feed tube by the ∩ type feed tube opening below of tube for transfusion [2].It is that the part that tube for transfusion [2] syringe needle passage is made progress is communicated with the bottom of floating valve [19] valve pocket and protrudes into valve body [19] inside, and the part that tube for transfusion [2] syringe needle passage is downward is communicated with the valve pocket middle and upper part of floating valve [19]; In the top perforate of floating valve [19] valve pocket, be used for installing and raise the nose above water to breathe [15], and perforate is processed into valve pocket is projecting inward and is advisable to improve sealing property; Raise the nose above water to breathe [15] through the perforate on valve pocket top, be flexibly connected with the seal valve [18] in valve body, seal valve [18] both can be processed into tabular also can be processed into inverted coniform or shape that other is suitable; To inner tube for transfusion and the perforate bore protruding of valve body [19] valve pocket, with little, tube wall, with thin, be advisable equally, make seal valve [18] reach maximum or hour at suffered buoyancy, seal valve [18] is to the enough large and raising sealing property of the pressure of the tube for transfusion bore protruding and perforate.In infusion process, after syringe needle inserts infusion bottle [1] and is inverted, floating head [15] upwards floats and pulls seal valve [18] and valve pocket top perforate to seal and open infusion channel and prepare transfusion, after medicinal liquid in the preceding infusion bottle of all infusion orders [1] is totally lost, under the effect of pipe negative pressure, the medicinal liquid in this infusion bottle [1] is inhaled into tube for transfusion [2] and continues transfusion; After this infusion bottle [1] herb liquid is totally lost, raise the nose above water to breathe [15] sink and promote seal valve [18] by the opening sealing of syringe needle passage floating valve protruding upward [19] valve pocket bottom, make liquid-transport pipe-line produce negative pressure and make infusion order after infusion channel enter transfusion state and automatic decanting continues transfusion until all infusion bottle herb liquids are totally lost.

In the present embodiment, also the syringe needle of tube for transfusion [2] only can be processed to the infusion channel that Open Side Down makes the structure of syringe needle more simply be easy to processing, and at the floating valve shown in the upper installation diagram 8 of each tube for transfusion [2], replace buoyancy control valve [13] or the floating valve shown in Figure 15 on syringe needle or Figure 16, when infusion bottle [1] herb liquid is totally lost, can produce negative pressure and make infusion order after infusion channel automatically enter transfusion state and complete automatic decanting, or at the upper check valve that can stop fluid reflux of only installing of tube for transfusion [2], check-valves or non-return flap etc. can only make the unidirectional valve body flowing downward of fluid, and suitably increase infusion order at rear infusion bottle [1] though in pressure medicinal liquid can not enter syringe needle infusion port or can enter but can not surpass the extreme higher position of syringe needle infusion channel, medicinal liquid in the preceding infusion bottle of infusion order [1] is totally lost the pressure of infusion channel while reducing, infusion order after tube for transfusion [2] on check valve, check-valves or non-return flap etc. are opened, infusion order after infusion bottle [1] in the effect of medicinal liquid at pressure of the inside of a bottle under enter tube for transfusion [2] in and automatic decanting, or while changing bottle with switch, clip etc. by infusion order after tube for transfusion close, after changing bottle, open again, only suitably increase infusion order at rear infusion bottle [1] though in pressure medicinal liquid can not enter syringe needle infusion port or can enter but can not be over the extreme higher position of syringe needle infusion channel, medicinal liquid in the preceding infusion bottle of infusion order [1] is totally lost the pressure of infusion channel while reducing, infusion order after infusion bottle [1] in the effect of medicinal liquid at pressure of the inside of a bottle under enter tube for transfusion [2] in and automatic decanting.

In conjunction with Figure 14, in the present embodiment, also 3 infusion channel can be linked together and carry out the transfusion of order automatic decanting, but need by order after the second and the 3rd infusion channel between increase (with what be advisable with liquid air bleeding valve only) visual dropper or other suitable container [4], original the second tube for transfusion [2] is stretched in the visual dropper [4] of increase and opening is processed into downward bend pipe [20], second with the method for attachment of the 3rd tube for transfusion [2] and the same visual dropper [4] that simultaneously stretches into increase of method of attachment of first and second tube for transfusion [2] originally.During transfusion, the second infusion channel that will be original is emptying, above the second tube for transfusion [2] of the visual dropper [4] increasing is filled with appropriate or is full of medicinal liquid, and will in the visual dropper [4] increasing, be filled with appropriate medicinal liquid, and the 3rd tube for transfusion [2] is still emptying.When the first liquid-transport pipe-line medicinal liquid is not totally lost, the medicinal liquid in the visual dropper [4] of increase can not enter the second infusion channel because of surface tension; After the first liquid-transport pipe-line medicinal liquid is totally lost, producing negative pressure sucks the medicinal liquid in the visual dropper [4] increasing to continue to infuse and reduce the pressure in the visual dropper [4] increasing, now in the tube for transfusion [2] on the second infusion bottle [1], be filled with medicinal liquid, transfusion response speed enters transfusion state than the upper emptying fast and first automatic decanting of tube for transfusion [2] of the 3rd infusion bottle [1] and continues transfusion, and the 3rd infusion channel is continued to sealing; Medicinal liquid in the second infusion bottle [1] produces again negative pressure after being totally lost, and the medicinal liquid in the 3rd infusion bottle [1] is sucked to tube for transfusion [2] automatic decanting and continue transfusion, completes automatic order and changes a bottle transfusion job.Now infusion order after the visual dropper [4] of increase more than the second tube for transfusion [2] with more short better, with reduce infusion order after infusion bottle [1] and the medicinal liquid in tube for transfusion [2] to cross High Voltage excessive and affect infusion order during the medicinal liquid in the visual dropper [4] increasing is pressed into the second original infusion channel.Equally also can use the same method 3 above infusion channel are connected in turn and carry out the transfusion of order automatic decanting, be that every increase by one infusion channel just needs increase by one inside to have the visual dropper of the transfusion bend pipe [20] that Open Side Down or suitable container [4].
