Detailed description of the invention
Automatic cut-off acoustic conductance dropping funnel, connect with outside upper tubing and outer subordinate's tube for transfusion and namely form disposable automatic cut-off acoustic conductance intravenous transfusion device, the design discharge of disposable automatic cut-off acoustic conductance intravenous transfusion device is much larger than the actual flow of venous transfusion, therefore in infusion process, all the time pressure is had in disposable automatic cut-off acoustic conductance intravenous transfusion device, come round in the acoustic conductance tympanum 1-2-4 reason acoustic conductance mouth 1-2-3 of automatic cut-off acoustic conductance dropping funnel and outside, therefore the pressure in acoustic conductance tympanum 1-2-4 is normal pressure, be less than tympanum 1-2-5, medicinal liquid pressure outside lower tympanum 1-2-7, in transfusion, lower tympanum will upwards have been opened, leave the eluate conduit inlet 1-3-3 of eluate conduit 1-3-2 below, after the decline of medicinal liquid face is totally lost by medicinal liquid, overpressure will disappear naturally, and the lower tympanum heaved will restore to the original state, and again covers eluate conduit inlet, occurs cut-off state.
Disposable automatic cut-off acoustic conductance intravenous transfusion device is in infusion process, identical with common disposable intravenous infusion set operation sequence, the hand-held new disposable intravenous transfusion device of medical personnel, first automatic cut-off acoustic conductance dropping funnel is inverted, to wear bottle is again needled in medicinal liquid bottle, medicinal liquid will flow in automatic cut-off acoustic conductance dropping funnel by upper tubing, when rising to the given medicinal liquid face graduation mark of automatic cut-off acoustic conductance dropping funnel in medicinal liquid face, slowly automatic cut-off acoustic conductance dropping funnel is turned again, come round in the acoustic conductance tympanum 1-2-4 reason acoustic conductance mouth 1-2-3 of automatic cut-off acoustic conductance dropping funnel and outside, therefore the pressure in acoustic conductance tympanum 1-2-4 is normal pressure, be less than tympanum 1-2-5, medicinal liquid pressure outside lower tympanum 1-2-7, at this moment in automatic cut-off acoustic conductance dropping funnel 1, lower tympanum 1-2-7 upwards will expand under pressure and heave, depart from the eluate conduit inlet 1-3-3 below it or spool inlet opening 2-3-4-2, form water conservancy diversion cavity, medicinal liquid can flow out from eluate conduit, flow in outer subordinate's tube for transfusion.
Because acoustic conductance tympanum 1-2-4 is positioned at dropping funnel inside in infusion process, medicinal liquid drips and can directly drop on tympanum 1-2-5, or drop on the medicinal liquid face that directly contacts with upper tympanum, drop sound is received in the greatest extent in acoustic conductance tympanum 1-2-4, and provides acoustic conductance mouth 1-2-3 to conduct to outside corollary system for venous transfusion monitoring administration provides information.
Disposable automatic cut-off acoustic conductance dropping funnel intravenous transfusion device, after medicinal liquid is close to automatic cut-off of being totally lost, liquid level no longer declines, there is transfusion halted state, the medicinal liquid now stayed in automatic cut-off dropping funnel and lower tube for transfusion still maintains certain pressure, avoids air and enters in lower tube for transfusion and the generation of reflux blood back phenomenon.
If continue transfusion, continuous bottle change dressings after operator only gently need pinch the dropping funnel epimere of automatic cut-off acoustic conductance dropping funnel, closed downcomer inlet 1-3-3 or spool liquid outlet 2-3-4-3 will open, and medicinal liquid starts flowing, 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, in production efficiency, under tympanum 1-2-4, tympanum 1-2-7 can adopt latex or silicone rubber elastomeric material to make, and guarantees and elastic effect
Automatic cut-off acoustic conductance dropping funnel provided by the present invention, it is novel in design, is skillfully constructed, takes full advantage of characteristic and pressure, gravity, the negative pressure acoustic conductance principle of liquid, reach the automatic cut-off of venous transfusion, sound conduction, the object of blood return prevention; Its automatic cut-off acoustic conductance structure is spacing in the liquid outlet one end in dropping funnel inside, do not affect formation and the observing effect of drop in dropping funnel, similar to the traditional appearance of common disposable intravenous infusion set dropping funnel, sound conduction structure does not affect the flow effect of automatic cut-off effect and medicinal liquid.
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.
