[detailed description of the invention]
The automatic anticoagulation of one as shown in Figure 1 stops liquid transfusion device, and bottle plug puncture unit 1 connects upper tubing 2, and upper tubing 2 connects dropper 16, and dropper 16 is connected with the upper cover of dropping funnel 4A.Under dropping funnel 4A, cervical region and lower tube for transfusion 9 connect, and lower tube for transfusion 9 and reservoir 15 connect, and reservoir internal capacity is 8 milliliters of liquid.In the blister cavities of reservoir 15, a support is extended to form to reservoir 15 intracavity from the inner surface of liquid storage operculum 15A, the lower end of this support is also connected with one piece of flow-stopping plate 4, in the region on the upper orifice that the position of flow-stopping plate 4 in reservoir 15 chamber is arranged on exhaustor 5.Flow-stopping plate 4 is circular slabs of one piece of horizontal, and diameter is less than the internal diameter at reservoir 15 capsule body position, but larger than the external diameter of exhaustor 5, and its circle centre position is on the central shaft of reservoir 15.Exhaustor 5 is that a lower end is plugged in the lower cervical region of reservoir 15, both ends open and two ends connect, upper orifice is positioned at the hollow pipe of the middle and upper part of reservoir 15, in reservoir 15, on the sidewall of exhaustor 5, offer a miniflow metering-orifice 6 in the position being arranged in close exhaustor 5 and reservoir 15 times cervical region joints, the flow velocity of this miniflow metering-orifice 6 is 2ml per hour.
Be connected to lower tube for transfusion 9 in the lower end of reservoir 15, be connected to only liquid liquid medicine filter (7) in the middle and upper part of lower tube for transfusion 9.The upper cover plate of only liquid liquid medicine filter (7) is equipped with water repellant air filter 8, in the cavity of only liquid liquid medicine filter (7), adopts the method for ultra-sonic welded to be welded with stop liquid liquid medicine filtering membrane 7A.Manage the outer place near outer cone joint 11 at lower tube for transfusion 9 and be equipped with flow regulator 10, cone joint 11 lower end is connected with capillary tube for transfusion 12 outside, is connected with flank 13 in capillary tube for transfusion 12 lower end, is connected with intravenous needle 14 in flank 13 lower end.
Using method:
After bottle plug puncture unit 1 and infusion bottle connect, transfusion enters in reservoir 15 by bottle plug puncture unit 1, upper tubing 2, dropper 16, dropping funnel 4A, it first wanders on flow-stopping plate 4, drop to the lower end of reservoir 15 again, and constantly gather in reservoir 15 bottom, causing the lifting of liquid level in reservoir 15, making the gas in reservoir 15 constantly by arranging in exhaustor 5 downwards tube for transfusion 9.When the mouth of pipe of liquid level and exhaustor 5 upper end flushes, the gas in reservoir 15 drains.Transfusion is input to 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 get rid of with regard to whole.
Along with constantly pouring in of transfusion, enter 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, flow through flow regulator 10, outer cone joint 11, capillary tube for transfusion 12, intravenous needle 14, finally gush from intravenous needle 14 syringe needle, so close flow regulator 10 at once, connect vein, mix up flow regulator 10, transfusion starts.
When the transfusion in infusion bottle is dripped to the greatest extent, transfusion liquid level in transfusion device 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, so transfusion liquid level maintains constant height, transfusion device just enters the state of only liquid.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 also remain the transfusion of more than half capsule in reservoir 15, that is because grafting exhaustor 5 in lower cervical region, make transfusion must by being passed under the upper orifice of exhaustor 5 in parts below.The flow velocity in miniflow hole 6 is arranged to 2ml because 20 transfusions are general form 1 milliliter, so flow velocity be exactly 90 seconds one.The volume of this reservoir 15 is arranged to 8ml, like this after only liquid starts, needs experience could residual transfusion is defeated most after one or two hour.These residual transfusions drop to and stop after on liquid liquid medicine filtering membrane 7A, and finally all have passed intravenous needle 14 and enter into vein, so during this period of time, intravenous needle 14 place would not stop, so blood coagulation phenomenon would not occur at this place.
Again because of till the supplementing of the liquid liquid medicine filtering membrane 7A acquisition transfusion that can continue in several hours after only liquid, so during this period of time effectively can prevent the liquid-sheet disintegration stopping the transfusion of adsorbing in liquid liquid medicine filtering membrane 7A fenestra, the use therefore extending original design stops the only liquid time that liquid liquid medicine filter stops the transfusion device of liquid.
