Detailed description of the invention
In venous transfusion, the tube for transfusion inner liquid medicine flow of disposable intravenous infusion set, because being subject to the Flow-rate adjustment restriction of tiny piercing needle and flow control valve, in the transfusion of the overwhelming majority, by the maximum stream flow flowing of design, can not make have pressure to exist in the inherent whole infusion process of tube for transfusion; Medicinal liquid simultaneously in infusion bottle is owing to there being certain height, therefore also in tube for transfusion, certain pressure is formed, when the medicinal liquid in infusion bottle reduces gradually, pressure in tube for transfusion also reduces gradually, when medicinal liquid stops flowing because of external pressure, tube for transfusion inner liquid medicine above cut-off point produces the malleation to tube for transfusion under gravity, below cut-off point, medicinal liquid in tube for transfusion produces the negative pressure to transfusing chamber under gravity, when the position of cut-off point is higher time, the negative pressure that the medicinal liquid below cut-off point produces is larger.
Bottle pin 1 is worn in automatic cut-off negative pressure conduction in this case, be linked and packed with tube for transfusion, form disposable automatic cut-off negative pressure conduction intravenous transfusion device, in infusion process, substantially identical with common disposable intravenous infusion set operation sequence, the hand-held disposable automatic cut-off negative pressure conduction intravenous transfusion device of medical personnel, first dropping funnel is inverted, insert in medicinal liquid bottle bottle pin is worn in the conduction of automatic cut-off negative pressure, wear a bottle pin to wear out bottle cap and directly enter into the liquid, extrude infusion unit titrimeter gently, cut-off diaphragm produces deformation under the effect of medicinal liquid pressure, leave medicinal liquid water conservancy diversion to chew, medicinal liquid will be chewed inflow tube for transfusion from medicinal liquid water conservancy diversion and flow in dropping funnel, when rising to the middle medicinal liquid face graduation mark of dropping funnel in medicinal liquid face, slowly dropping funnel is turned again, medicinal liquid will flow in lower tube for transfusion from dropping funnel liquid outlet, after the air in tube for transfusion is discharged completely, medicinal liquid just flows out from venous needle, flow into after venipuncture in the vein blood vessel of patient, enter transfusion state.
In transfusion process, under the pressure effect of the medicinal liquid gravity conversion of cut-off diaphragm in medicinal liquid bottle of water conservancy diversion cut-off module, remain that the movable chamber of deformation cut-off diaphragm is upward protruded, medicinal liquid water conservancy diversion is chewed completely unlimited, ensure that the unimpeded of medicinal liquid stream, when the medicinal liquid in medicinal liquid bottle is totally lost, medicinal liquid face in medicinal liquid bottle declines, the pressure of cut-off diaphragm is reduced, be difficult to the deformation maintaining cut-off diaphragm, cut-off diaphragm restores to the original state, sealing fits in medicinal liquid water conservancy diversion and chews, medicinal liquid water conservancy diversion is chewed and is in air-tight state, block the flowing of medicinal liquid, tube for transfusion is made to be in cut-off state, liquid level no longer declines, there is transfusion halted state, now stay the medicinal liquid of tube for transfusion, in tube for transfusion under cut-off state, medicinal liquid pressure is much larger than human vein pressure, the pressure that after cut-off, in tube for transfusion, hypomere is too much, stop surface place is converted into negative pressure up, maximum in the negative pressure at stop surface place, conduct to outer welding system by negative pressure conduction module, be in pressure balance in tube for transfusion simultaneously, avoiding air enters in tube for transfusion and the generation of reflux blood back phenomenon.
As transfusion need be continued, continuous bottle change dressings after operator only gently need pinch dropping funnel, cut-off diaphragm generation deformation is to cut-off diaphragm movable projection, and water conservancy diversion sealing is chewed and will be opened, and the pressure balance of tube for transfusion inner liquid medicine is broken and flows downward, and enters continuation transfusion state.
In process of production, the structural member in this case adopts conventional manufacturing techniques to produce, and manufacturability is strong, and production cost is low; Adopt the manufacture of multimode injection moulding, production efficiency; Cut-off diaphragm adopts the medical poisonless silica gel material of dead-soft to make, and increases its pliability and deformation quantity, guarantees medicinal liquid flow velocity and sealing effectiveness.
Automatic cut-off negative pressure conduction provided by the present invention wears a bottle pin, good sealing effect, stable and reliable for performance; Its cut-off diaphragm design, wearing in bottle pin, does not substantially change the structure of common disposable intravenous infusion set, face shaping, does not affect drop observing effect in dropping funnel; Do not affect flow velocity; Be equipped with disposable intravenous infusion set of the present invention, do not change the work habit of medical personnel, its operation sequence is identical with disposable intravenous infusion set, is easy to learn and use; Compared to other stopper, there is structure simple, good sealing effect, the features such as manufacturability is strong; Medical personnel's labor intensity can be effectively reduced in clinical practice, save a large amount of human resources taken for observing transfusion progress, making infusion management more specification, nursing more intimate.
