Beneficial effect
The invention provides a kind of single intravenous infusion volume dropping funnel, it utilizes stethoscope and micropkonic principle, in infusion process, pass through voice collection device, accurately gather the speed of dripping of medicinal liquid drop, connect outer welding system transfusion speed is precisely controlled, to realize the precision transfusion on gravity infusion basis.Compared to other precision transfusion device, the feature such as the present invention has simple in structure, and flow velocity monitoring effect is good, and volume small occupied space is few, and manufacturability is strong, and technological expansion space is large; In clinical practice, can effectively control transfusion speed, automatic cut-off, not only improves nursing quality, energy-conserving and environment-protective, also has darker technology wider space, and the real time imaging that makes to infuse monitoring becomes possibility.
Detailed description of the invention
Conventional disposable intravenous infusion set generally includes: wear a bottle pin, upper tubing, dropping funnel, lower tube for transfusion, flow control valve, air filtration bubble, capillary soft tube, puncture needle, in infusion process, the Peak Flow Rate of medicinal liquid is subject to medicinal liquid suspension height, wear a bottle pin hole footpath, upper and lower tube for transfusion caliber, capillary soft tube caliber, the impact in puncture needle aperture, and under the regulating action of flow control valve, be less than in the scope of Peak Flow Rate and regulating, the particular design of dropping funnel makes medicinal liquid forming drop in the time that upper tubing enters dropping funnel, thereby can judge transfusion speed according to the speed of dripping of drop, accumulate the medicinal liquid of certain altitude at the lower semisection of dropping funnel simultaneously, more be convenient to medicinal liquid to drip fast observation, Novel vein transfusion volume dropping funnel is according to the feature of conventional intravenous transfusion device, in dropping funnel, use stethoscopic principle to add volume device, make drop be dropped in the drum surface of volume device, judge flow velocity by drop being dripped to fast analysis, use procedure and conventional transfusion device are basic identical, open after the transfusion device that Novel vein transfusion volume dropping funnel is housed, Novel vein transfusion volume dropping funnel is inverted, when in dropping funnel, contain lower than dropping funnel hypomere or sound conduit height medicinal liquid time just putting dropping funnel, outer welding system is connected into sound leadout hole or the dropping funnel outer catheter part of the sound conduit of dropping funnel hypomere and fluid pipeline are affixed in outer welding system, on welding system, set outside after required transfusion speed, medicinal liquid enters dropping funnel feed tube through upper tubing, form drop at dropping funnel feed liquor mouth of pipe place, drop on the tympanum that is positioned at the Centromedian volume device of dropping funnel, the sound that the tympanum forming between tympanum shell and tympanum forms the shock tympanum drum surface of drop produces and expands, gather and conduction, by the sound conduit being connected with tympanum, sound wave is transmitted to outer welding system, outer welding system can be added up the frequency that draws drop to the sound wave of drop, because the caliber of the dropping funnel feed liquor mouth of pipe is fixed, the volume size of drop is also certain, so can judge the flow velocity of medicinal liquid in transfusion device by the frequency analysis of the drop sound wave to gathered, and use outer welding system by adjusting tube for transfusion caliber, control drop frequency and reach required transfusion speed, in infusion process, can use image collection and the real-time infusion monitoring situation of transmission system of external system configuration, realize the high-end medical treatment and nursing such as remote adjustment transfusion speed, when transfusion finishes, tympanum in dropping funnel exceedes to be set adjacent two drops physic liquors that transfusion speed is corresponding and fails to collect acoustic information interval time, outer welding system just can be according to circumstances completely the medicinal liquid in stopping infusion apparatus flow and realize transfusion cut-off, prevent that transfusion from finishing transfusion device and can not end in time the complication after punctures such as the blood back that causes.If continue to infuse, only need replacing medicinal liquid bottle the cut-off of welding system releasing outside or set new infusion flow rate to enter continuation transfusion state.
The outer welding system one assembling of Novel vein transfusion volume dropping funnel and separate case application, forms venous transfusion flow speed control device; It forms disposable accurate intravenous transfusion device after being connected with upper tubing and lower tube for transfusion.Under the support of welding system outside of disposable accurate intravenous transfusion device, can on the basis of gravity infusion, realize transfusion speed presets, also can limit in fact the long-range real-time monitoring of transfusion speed and real-time pictures monitoring in venous transfusion process, for the realization of high-end transfusion nursing is laid a good foundation.
In process of production, the structural member in this case adopts conventional production technology to produce, and manufacturability is strong, and production cost is low; Adopt the manufacture of multimode injection moulding, production efficiency is high; Tympanum can adopt more soft, and the latex material that elasticity and toughness are stronger is made, and can guarantee that the sealing of tympanum, to strengthen expansion and the collecting effect to drop sound, meanwhile, increases overall appearance effect.
Novel vein transfusion volume dropping funnel provided by the present invention, rational in infrastructure, deft design, energy-saving safe, stable and reliable for performance; Its voice collection device, in the liquid outlet one end in dropping funnel inside, does not affect formation and the observing effect of drop in dropping funnel, does not increase the volume of dropping funnel and affects outward appearance, similar or close to the traditional style of disposable general infusion set dropping funnel; Dropping funnel liquid outlet can directly connect with lower tube for transfusion, do not affect the flow effect of medicinal liquid, its amount of flow is more than or equal to defined flow standard in GB, by sound conduit, design fixing dropping funnel is had to initiative, for more high-end long-range monitoring infusion provides technical support and basis.
Be equipped with disposable accurate intravenous transfusion device of the present invention, do not change medical personnel's work habit, its operation sequence is identical with conventional disposable intravenous infusion set, is easy to learn and use; Compared to other current velocity controller, have simple in structure, energy-saving safe, the feature such as follow-up extending space is large, and manufacturability is strong; In clinical practice, can effectively reduce medical personnel's labor intensity, save a large amount of human resources who takies for regulation and control transfusion speed, make the more convenient specification of infusion management, nurse more intimate.
