Description
[technical field]
The present invention relates to disposable infusion set, be particularly useful for single use anticoagulant and stop liquid transfusion device.
[background technology]
The only liquid transfusion device had at present, after only liquid starts, just infuses never again and is passed to intravenous by under intravenous needle again.General patient, after only liquid after a while, if do not have nurse to process it, just has sludged blood and produces at intravenous needle place; And the critically ill patient that other nearly all disease is planted, all can cause the disorder of coagulation function, if this patient uses only liquid transfusion device, after stopping liquid, in the short period of time, will there is blood coagulation in intravenous needle.Once generation sludged blood, patient will be made panic, even cause doctor-patient dispute.
In order to solve such problem, occurred adopting under dropping funnel cervical region plug-in mounting one to stretch to dropping funnel intracavity, the exhaustor of a miniflow metering-orifice is established in bottom, is connected to the method for designing of only liquid liquid medicine filter below dropping funnel.This design is exactly in order to transfusion can be made to drip to the greatest extent, utilizes exhaustor to retain transfusion in dropping funnel, and the miniflow metering-orifice utilizing exhaustor and exhaust pipe lower part to be provided with is passed under guiding the residual transfusion be retained down and stops in liquid liquid medicine filter.But due to after defeated using up of infusing, the transfusion in original exhaustor is whole defeated most, so be empty inside exhaustor, after the transfusion therefore penetrated in exhaustor will form the transfusion pillar of certain altitude, could form the strength fallen.Because this hole is miniflow, so the lower defeated period distances that can make to be divided in dropping funnel lower defeated transfusion is several times longer, in gap periods, easily cause the sludged blood that intravenous needle place causes.And the residual transfusion in the dropping funnel finally penetrating in exhaustor, if the transfusion pillar that its is formed is not high enough, the transfusion that also just cannot remain in defeated dropping funnel to the greatest extent.
And the method also had installs an exhaustor in dropping funnel, collet is established a miniflow metering-orifice under dropping funnel, below miniflow metering-orifice, connect a drainage tube be connected to only on liquid liquid medicine filter upper cover; Or in dropping funnel, an exhaustor is installed, lower collet is established a non-miniflow metering-orifice, below non-miniflow metering-orifice, connects a micrometeor drainage tube be connected to only on liquid liquid medicine filter upper cover.Although they can not as the miniflow metering-orifice utilized on exhaustor and exhaustor as the path defeated in only liquid liquid medicine filter of transfusion residual in dropping funnel method gap periods between the transfusion that every part in dropping funnel can be made to export down go very long.But because the ordinary circumstance after only liquid is that nurse has just processed a moment later at once, so most so residual transfusion just will to be dropped and by slatterning in vain because of not carried.
[summary of the invention]
In order to overcome the above-mentioned deficiency of only liquid transfusion device, the present invention proposes a kind of anticoagulation with flow changer and stops liquid transfusion device, it is passed to intravenous under only liquid transfusion device can being made when only liquid to make intravenous needle be in can to have the transfusion of trace within several hours always, therefore can avoid above-mentioned because of till liquid overlong time and the blood coagulation phenomenon that intravenous needle place is occurred, if again can when nurse processes transfusion device in time, avoid because only liquid time is too short and can not be defeated most by the residual transfusion in dropping funnel, and the phenomenon of the transfusion waste caused.

Beneficial effect: 1), only liquid transfusion device can be avoided when only liquid, to prevent the only liquid time long and there is the function setting of blood coagulation at intravenous needle place after because adding, the another one drawback brought---the waste of transfusion also can be caused when only liquid is too short.In the present invention, exhaustor upper opening, bottom is plugged on the lower cervical region of dropping funnel, is provided with only liquid liquid medicine filter, is provided with flow velocity changer flow velocity can exchanged from miniflow to non-miniflow in the interval between the convex pipe of described A to the convex pipe of B in the tube for transfusion of dropping funnel bottom.When only liquid starts, also have the residual transfusion of several milliliters to be retained by exhaustor in dropping funnel, only the liquid level of liquid is positioned at only liquid liquid medicine filter only liquid liquid medicine filtering membrane place, has then filled with transfusion in drainage tube.From that time, the residual transfusion of dropping funnel just can utilize the miniflow function of flow velocity changer, and by the drainage of drainage tube, automatically, be passed under oneself being continued in the mode of tens seconds miniflows of and stop in liquid liquid medicine filter, centre there will not be disruption.The transfusion be passed under these in only liquid liquid medicine filter all can continue synchronized defeated downwards, finally all can be passed in vein by under intravenous needle.So avoid this place because the long period do not infuse flowing and produce blood coagulation.And if after stopping liquid, nurse processes very early, and the residual transfusion so in dropping funnel will be detained a lot, if pull out transfusion device at this point, will cause the waste of transfusion.Because the flow changer be nested with outside drainage tube pipe has the function that flow velocity is changed from miniflow to non-miniflow, so before transfusion device is pulled out, as long as after nurse converts the flow velocity of flow changer to non-miniflow, just can be defeated most within a few second by the residual transfusion be left in dropping funnel.So this programme avoids the blood coagulation problem that is that produce at intravenous needle place because the only liquid time that solves is long, turn avoid after stopping liquid, if when nurse processes transfusion device at once, several milliliters of transfusions residual in dropping funnel can be made because major part does not all have the defeated waste caused to the greatest extent.
2), extend application and stop liquid liquid medicine filter to stop the only liquid time of the transfusion device of liquid.Only the only liquid time of liquid liquid medicine filtering membrane is different because the material of only liquid liquid medicine filtering membrane is different, and what have only has tens minutes, and what have can have more than dozens of minutes hour.Chief reason stops the liquid-sheet disintegration of the transfusion formation of adsorbing in liquid liquid medicine filtering membrane fenestra.Supplementing of the acquisition liquid that only liquid liquid medicine filtering membrane of the present invention can continue in the quite a while after stopping liquid, the liquid film avoided in only liquid liquid medicine filtering membrane fenestra breaks because of the overlong time of experience, so only the time of liquid will only liquid transfusion device be longer than original.

[detailed description of the invention]
Embodiment one,
As shown in Figure 1 be the center longitudinal section that a kind of anticoagulation with flow changer stops liquid transfusion device, bottle plug puncture unit 1 connects upper tubing 2, and upper tubing 2 connects dropper 3, and dropper 3 is connected with dropping funnel lid 15A.
Stretch to dropping funnel 15 intracavity at the lower cervical region plug-in mounting one of dropping funnel 15, two ends are provided with opening, the exhaustor 5 of inner hollow, and the sidewall upper of exhaustor 5 has a steam vent 4C, the position of steam vent 4C be located at dropping funnel pipe high 1/2 ~ 2/3 between.The upper bottom surface of exhaustor 5 is the drain slopes 4 arranged towards the direction deviating from described steam vent 4C.In the edge on drain slope 4 being positioned at that side of steam vent 4C, extend to form the shelves stream plate 4A of a block length shape towards the direction deviating from drain slope 4.Microscler shelves stream plate 4A is by the dual-side of a block length strip along parallel and the surface plate put and the plate that hangs down from its dual-side along or triangle drain rectangular respectively towards downward two pieces of stretching out are formed, and the hang down edge of plate and the sidewall of exhaustor 5 of drain connects.Drain hangs down the lowest part on edges of boards edge lower than the position of steam vent 4C place exhaustor 5, makes shelves stream plate 4A steam vent 4C be covered on the inside.In whole shelves stream plate 4A orthographic projection in the horizontal direction, its widest position is no more than the diameter of exhaustor 5, and shelves stream plate 4A outer end upwards extends to form a protruding shelves stream bar 4B.
From in dropping funnel 15 collets, in the region outside lower cervical region, an optional place extends to form a pit downwards, and this pit is the lowest part of dropping funnel 15, arranges a guiding fluid hole 6 in the lowest part of dropping funnel 15.On the outer wall of dropping funnel 15, stretch out in the periphery of guiding fluid hole 6 formation convex pipe of adapter mouth B, connects a drainage tube 6A outward at the convex pipe of B.
Be connected to lower tube for transfusion 9 in dropping funnel 15 lower end, be connected to only liquid liquid medicine filter 7 in the middle and upper part of lower tube for transfusion 9.The upper cover of only liquid liquid medicine filter 7 is equipped with water repellant air filter 8, the lower port adopting the method for ultra-sonic welded to be welded with only liquid liquid medicine filtering membrane 7A, drainage tube 6A in the cavity of only liquid liquid medicine filter 7 is just connected on the convex pipe of adapter mouth A that the upper cover of only liquid liquid medicine filter 7 extends out.
In the convex pipe of A or in the convex pipe of B or in drainage tube 6A, a flow is installed and exchanges valve 6B, the shaft portion being arranged in the convex pipe of A or the convex pipe of B or drainage tube 6A pipe of flow exchange valve 6B has the infusion channel of more than two, wherein a passage is micrometeor passage, other be all non-micrometeor passage.
Flow regulator 10 is equipped with outside the pipe of lower tube for transfusion 9 bottom, outer cone joint 11 is connect bottom at lower tube for transfusion 9, be connected with capillary tube for transfusion 12 below cone joint 11 outside, be connected with flank 13 in capillary tube for transfusion 12 lower end, be connected with intravenous needle 14 in flank 13 lower end.
Using method:
After bottle plug puncture unit 1 and infusion bottle connect, infuse and enter in dropping funnel 15 by bottle plug puncture unit 1, upper tubing 2, dropper 3, then drop on the drain slope 4 of exhaustor 5 upper end.The transfusion major part fallen on drain slope 4 follows the most labour-saving characteristics of motion, the lower end flowing to and exhaustor 5 has been fallen dropping funnel 15 is again climbed downwards along drain slope 4, only have a small amount of transfusion due to crowded and upwards drive in the wrong direction climb flow to shelves stream plate 4A surface plate on, climb downwards again and flow to drain and hang down on plate, finally drop to dropping funnel 15 lower end.The transfusion dropping to dropping funnel 15 lower end, constantly in dropping funnel 15 inner accumulated, causes the lifting of liquid level, gas is constantly passed through in dropping funnel 15 the exhaustor 5 interior row of tube for transfusion 9 downwards.When the steam vent 4C of liquid level and exhaustor 5 upper end flushes, the gas in dropping funnel 15 drains.Transfusion is input to downwards by exhaustor 5 and stops in liquid liquid medicine filter 7, contaminates wet by the only liquid liquid medicine filtering membrane 7A in it.Remain in the air stopped in liquid liquid medicine filter 7 subsequently outwards to arrange by stopping the water repellant air filter 8 that liquid liquid medicine filter 7 upper cover plate is installed, until all eliminatings with regard to whole.
Along with constantly pouring in of transfusion, entering the transfusion stopped in liquid liquid medicine filter 7 defeated through stopping in the downward tube for transfusion of liquid liquid medicine filtering membrane 7A 9, flowing through flow regulator 10, outer cone joint 11, capillary tube for transfusion 12, intravenous needle 14, finally gushs from intravenous needle 14 syringe needle, so close flow regulator 10 at once, connect vein. check that flow exchanges valve 6B, when confirming that drainage channel is positioned at micrometeor shelves, mix up flow regulator 10, transfusion starts.
When the transfusion in infusion bottle is dripped to the greatest extent, transfusion liquid level in tube for transfusion constantly declines, when liquid level is down to the position of only liquid liquid medicine filtering membrane 7A, the tension force that the transfusion of adsorbing in fenestra is formed just has deadened air and has entered into lower tube for transfusion 9, make transfusion liquid level maintain constant height, transfusion device starts to enter into only liquid status.Till cause, liquid liquid medicine filter (7) is positioned at the middle and upper part of lower tube for transfusion 9, so make infusion pressure overcome the pressure of vein, blood can not be backflowed in tube for transfusion, avoid meeting with the static minute bubbles that adsorb on tube for transfusion tube wall and forming sludged blood.
After only liquid starts, the position of liquid liquid medicine filtering membrane the 7A to end although liquid level in tube for transfusion declines, but because have the existence of exhaustor 5 in dropping funnel 15, and the steam vent 4C of exhaustor 5 upper end is positioned at the middle and upper part of dropping funnel 15, so also remain the transfusion of more than half dropping funnel in dropping funnel 15.According to national standard, the minimum outer volume of dropping funnel 15 can not be less than 10 milliliters, so this part residual transfusion can more than 4 milliliters.Because drainage tube 6A is positioned at the below of dropping funnel 15, so make infusion device for potential energy, again because the flow be nested with outside drainage tube 6A exchanges valve 6B be in micrometeor state, so the guiding fluid hole 6 that is arranged on dropping funnel 15 lowest part just can the transfusion remained in dropping funnel 15 slowly, be carried automatically in drainage tube 6A.Because be just filled with transfusion before drainage tube 6A stops liquid in inherence, as long as so one has transfusion to be input in drainage tube 6A, the lower end port connecting the convex pipe of A of its lower end port at once just there will be the transfusion of spilling.Under the effect of microfluidic valve miniflow function, often just can form one by tens second time at the lower end port of the convex pipe of A and to drip the transfusion fallen, infuse with lower of such speed to last till in dropping funnel 15 always debris defeated to the greatest extent after just can terminate.All transfusions dropped onto in only liquid liquid medicine filter 7 can continue synchronized defeated downwards, finally all have passed intravenous needle 14 and are input in vein, so during this period of time would not make intravenous needle 14 place that sludged blood occurs.
The only liquid limit that till cause, liquid liquid medicine filter 7 is general only has dozens of minutes, because when stopping the liquid-sheet disintegration of the transfusion formation of adsorbing in liquid liquid medicine filtering membrane 7A fenestra, only liquid just stopped.Because within the time of these hours, can have transfusion being added dropwise to only on liquid liquid medicine filtering membrane 7A slowly, so when the residual transfusion in dropping funnel 15 is dripped most, only the liquid time of stopping of liquid liquid medicine filtering membrane 7A can also extend several hours always.
If just only liquid just has nurse to process transfusion device, be on miniflow shelves, so only had small part to be gone by lower output by the residual transfusion that exhaustor 5 is retained down in dropping funnel 15 because flow exchanges valve 6B.In order to avoid the waste of transfusion, as long as before pulling out transfusion device, the flow shelves of flow being exchanged valve 6B exchange into non-micrometeor from micrometeor, just can make the residual transfusion in dropping funnel 15 within a few second just by lower totally defeated.
