The specific embodiment
New disposable is from ending intravenous transfusion device, internal diameter and the flow of each section of tube for transfusion on its puncturing head sword-shaped needle, all be greater than internal diameter and the flow of scalp acupuncture, therefore in whole infusion process, scalp acupuncture prevention and the medicinal liquid reduced in transfusion device flow, infuse the organ inner liquid medicine in the normal pressure state, and increase gradually because of the height different pressures from top to bottom; Medicinal liquid in medicinal liquid bottle is totally lost, be positioned at the automatic cut-off device on threeway pressure conduction device, cut-off closed transfusion pipeline, and the medicinal liquid of the lower tube for transfusion in transfusion state continues to flow downward, negative pressure state occurs in tube for transfusion below stop surface, and reduce gradually with the different negative pressure of the height of stop surface from top to bottom; Be positioned at the composite tee pressure conduction device under stopper, from transfusion, start to finish to have passed through from just being pressed onto a change procedure of negative pressure to transfusion, in infusion process, in tube for transfusion always in the normal pressure state, transfusion approaches and finishes the decline of medicinal liquid face, stopper changes the negative pressure state into after starting cut-off in the tube for transfusion under stop surface.
In the reality transfusion, medicinal liquid bottle generally is suspended on about the two meters height apart from ground, under the adjusting of scalp acupuncture resistance and infusion flow control valve, its medicinal liquid flows downward far below the tube for transfusion maximum stream flow, tube for transfusion and the three-way flow guide intracavity that is communicated with it, in the normal pressure state, are positioned at the outer surface of the latex sealed pouch of diversion cavity, are subject to the compressing higher than medicinal liquid pressure around the pouch internal air pressure, to center, shrink, the air in pouch is extruded from sealed joint pipe discharges; When continuous bottle or transfusion end, be positioned at the stopper closed transfusion pipeline on three-way device, stop medicinal liquid to flow, and the medicinal liquid in lower liquid-transport pipe-line is under action of gravity, still the flow tendency that keeps down, now changes the negative pressure state into by the normal pressure state in threeway medicinal liquid circulation duct, under the outer surface negative pressure effect around of the latex pouch in transverse pipe, expand and launch, air flows in pouch by sealed joint pipe.
Provided by the utility model disposable from ending intravenous transfusion device composite tee pressure conduction device, be arranged between Murphy's dropper and lower tube for transfusion; Medicinal liquid pressure in transfusion on three-way device, can extrude the air in the latex pouch, and the design attitude that it is close to from stopper makes it after cut-off, can produce maximum negative pressure value, guarantees result of use; The design of latex pouch and sealing installation structure thereof is ingenious had rationally both isolated the pollution of air to medicinal liquid, brought into play again tee-joint function, kept air relatively mobile.
This utility model is simple in structure, is convenient to suitability for industrialized production, can adopt a mould bull injection moulding to produce, and output is high, and assembling is fast, and cost is low, high efficiency.The latex pouch adopts comparatively soft, the medical material production had no side effect, and pouch is regulated and is changed greatly, and working effect is reliable.
