Background technology
General infusion set relies on action of gravity that medicinal liquid is imported human vein from medicine bottle, will fail when most at medicinal liquid, can not stop to continue transfusion.For avoiding occurring contingency, the way in the reality is to rely on manual observation, and when being totally lost, medical personnel or nursing staff be in time artificial to stop transfusion at medicinal liquid.In this case, bring problems: 1, manual observation medicinal liquid position and control transfusion, will expend too big energy, increase too much work and work, needs of patients is infused and many bottles when infusing for a long time, and patient and care-giver have a hard time for this reason; If 2 have carelessness slightly, when will using up, medicinal liquid fails in time to stop infusing, and medicinal liquid all is totally lost the back air followed by entering patient's blood vessel, have influence on patient's life security when serious, and when changing medicine bottle, the medical worker gives patient's piercing needle once more if desired, also brings misery to the patient.3, patient and care-giver neglect always unavoidably because energy expends excessively, contingency occurs easilier, increase unnecessary damages and misery to the patient.If 4 hospital are responsible for nursery work, unnecessary medical tangle will be increased.
Summary of the invention
For working strength and the workload that alleviates the care-giver, reduce patient's misery, avoid the generation of contingency, but this utility model provides a kind of transfusion device of automatic stop blood return prevention, will fail when most at medicinal liquid, and stop automatically continuing transfusion, and in transfusion device, keep the medicinal liquid of some and certain altitude position, both the air admission vein can be prevented, also blood back can be prevented.
The technical scheme that its technical problem that solves this utility model adopts is:
This utility model is by bottle plug puncture unit, air inlet pipe, pipeline, form from stop controller, dropper, dropping funnel, liquid medicine filter, flow regulator, outer cone joint, flexible pipe, needle set, wherein be made up of outer chamber enclosure, interior chamber enclosure, feed tube, drain pipe, controlling diaphragm and control line from stop controller, controlling diaphragm is a deformable material.On any position of pipeline, increase by one from stop controller, be communicated with line seal from stop controller.Profile from stop controller is cylindric, inner hollow.Outer chamber enclosure and interior chamber enclosure are concentric, outside the chamber enclosure, chamber enclosure and interior chamber enclosure fastening place established the deformable film of one deck outside, are called controlling diaphragm in outer chamber enclosure was fastened on, to in stop controller, be divided into two isolated fully mutually chambeies in the space, be called inner chamber and exocoel.Feed tube and drain pipe respectively with intracavity inter-connection, feed tube is " L " type, drain pipe is inverted "L" shaped.The feed tube upper end is communicated with upper pipeline, and the feed tube horizontal ends is concentric with interior chamber enclosure, end face and controlling diaphragm isoplanar.The drain pipe lower end is communicated with the bottom pipeline, and the drain pipe horizontal ends is at the inner chamber outer casing bottom, end face and inner chamber outer casing bottom isoplanar.Exocoel communicates with atmosphere by exocoel cover top portion circular hole.Control line of controlling diaphragm central bolt extends beyond the outer chamber enclosure by exocoel cover top portion circular hole.
Under such structural design, under the different pressure action in controlling diaphragm both sides, finish the function of automatic stop from stop controller.
At first clearly, be convenient to analyze and set forth from the notion of the various pressure in stop controller inner control film both sides.
Interior intracavity is called intrinsic pressure to the pressure of controlling diaphragm, outer intracavity is called external pressure to the pressure of controlling diaphragm.Feed tube communicates with medicine bottle, and the position height of medicinal liquid is called hydraulic pressure to the pressure of controlling diaphragm, and medicine bottle communicates with atmosphere, is an atmospheric pressure, is called air pressure, and the inner chamber drain pipe communicates with human vein, and after the medicinal liquid output, inner chamber will have negative pressure, be called negative pressure.Exocoel communicates with atmosphere, and outer intracavity is called external pressure to the pressure of controlling diaphragm, and external pressure is an atmospheric pressure.Controlling diaphragm has certain pressure when distortion, be called mould.
If medicinal liquid is arranged in the medicine bottle, intrinsic pressure=hydraulic pressure+air pressure, external pressure=air pressure, intrinsic pressure＞external pressure, controlling diaphragm bloats to exocoel, pipeline connection, normal infusion.At this moment produce mould, after adding external pressure with intrinsic pressure balance.
If the medicine bottle inner liquid medicine will be failed to the greatest extent, hydraulic pressure reduces, external pressure+mould＞intrinsic pressure, and controlling diaphragm progressively resets, and reduces amount of infusion, and inner chamber progressively produces negative pressure.When hydraulic pressure+air pressure=external pressure+negative pressure and mould=0, controlling diaphragm has just sealed feed tube, owing to there is not medicinal liquid to continue to enter inner chamber, the inner chamber gas compartment increases, negative pressure rises rapidly, at this moment intrinsic pressure=negative pressure, external pressure＞intrinsic pressure, controlling diaphragm bloats to inner chamber, under the effect of external pressure, seal feed tube inflexibly, and along with the medicinal liquid of part below stop controller continues to fail down, negative pressure is increasing, and controlling diaphragm sealing feed tube is also more and more closely knit, when staying medicinal liquid fluid column pressure in the transfusion device and balance each other, transfusion stops fully up to negative pressure.
When inner chamber is negative pressure, controlling diaphragm sealing feed tube can make controlling diaphragm to the exocoel displacement deformation by manually gently drawing control line, thereby feed tube and drain pipe are connected, be convenient to first when using transfusion device, when changing bottle or for the medicinal liquid in the transfusion device is all defeated can Artificial Control to the greatest extent the time.
The beneficial effects of the utility model are: will fail when most at medicinal liquid, and stop transfusion automatically, and keep the medicinal liquid of some and certain altitude position, the control of can infusing as required when needing Artificial Control in transfusion device.Concrete advantage is: 1, alleviate care-giver's working strength and workload; 2, prevent into air and blood back, ensure medical safety; 3, alleviate patient's misery; 4, avoid unnecessary medical tangle; 5, medicinal liquid can Artificial Control be totally lost, and avoids waste and ensures medical effect; 6, simple in structure, with low cost, be convenient to suitability for industrialized production.
