Description
Technical field
The present invention relates to one from aerofluxus Anti-bubble automatic liquid-stopping precision filter infusion set, belong to medical instruments field.
Background technology
Transfusion is widely used Therapeutic Method in clinical treatment, and safety is the indispensable essential condition of transfusion.
In the time that general infusion set herb liquid starts to enter dropping funnel, very easily form the mixture of gas and liquid, this gas-liquid mixture can enter rapidly in the infusion pipeline of dropping funnel below, bubble phenomenon while forming transfusion, the healthy of patient threatened, so medical personnel, in the time of transfusion, infuse after the bubble in transfusion catheter must being discharged completely again.Conventionally the method adopting is, needle for inserting bottle is being thrust after transfusion bottle stopper, be inverted or extruding dropping funnel, medicinal liquid is entered in dropping funnel, when rapidly dropping funnel being returned to normal operating condition again after the liquid that is filled with half left and right in dropping funnel, nonetheless, on tube wall below dropping funnel, also often adsorb bubble, also need medical personnel to pinch bubble with finger bullet, this kind of operational approach is comparatively loaded down with trivial details, brings great inconvenience to medical personnel.
After medicinal liquid is totally lost, if do not process in time, in pipeline, will enter air, and can threaten to the healthy of patient equally.For avoiding this kind of situation, when common clinical transfusion, need patient and medical personnel's moment to close injecting medical liquid surplus, take very large energy, also patient is caused to larger mental pressure simultaneously, remain when more and just call medical personnel through the medicinal liquid of being everlasting, easily cause doctor-patient relationship contradiction, be unfavorable for the carrying out of Rehabilitation and normal medical and nursing work.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide a kind of simple in structure, easy to use and safe from aerofluxus Anti-bubble automatic liquid-stopping precision filter infusion set.
Of the present invention from aerofluxus Anti-bubble automatic liquid-stopping precision filter infusion set, comprise needle for inserting bottle, infusion pipeline, dropping funnel, flow regulator, cone joint and venoclysis needle, automatic exhauster is set in dropping funnel, automatic exhauster comprises from exhaustor and air-filtering membrane, be fixed on dropping funnel bottom from exhaustor lower end, in exhaustor, there is the exhaust hole that is communicated with dropping funnel inner chamber and ambient atmosphere, air-filtering membrane is fixed on from exhaustor top, the inner side of dropping funnel bottom arranges Anti-bubble device, Anti-bubble device is the aerofluxus core of hollow, the sidewall of aerofluxus core is provided with lead channel, aerofluxus in-core chamber communicates with the drain pipe of dropping funnel lower end, aerofluxus core, the drain pipe of dropping funnel bottom and dropping funnel lower end adopts integrative-structure, the top of aerofluxus core arranges only liquid device.
The port of export of described drain pipe adopts hole enlargement transition region, the internal diameter of hole enlargement transition region is greater than the internal diameter of epimere drain pipe, and hole enlargement transition region from top to bottom internal diameter increases gradually, avoid the drain pipe port of export and pipeline delivery position to occur significantly radially drop, prevent that gas is because accumulating in and form bubble herein with the areal pressure difference of the surface tension difference of medicinal liquid, delivery position, get rid of bubble enters dropping funnel below infusion pipeline hidden danger with medicinal liquid, use safety, and without being inverted dropping funnel, easy to operate while use.Wherein, the length of hole enlargement transition region is not less than 1.5mm, and the top internal diameter of hole enlargement transition region and the difference of bottom internal diameter are not more than 0.6mm, and the difference of the bottom internal diameter of the port outside diameter of the drain pipe port of export and hole enlargement transition region is not more than 0.6mm.
Described only liquid device is a liquid medicine filtering membrane, liquid medicine filtering membrane is fixed on aerofluxus core top, this liquid medicine filtering membrane is the permeable filter membrane of choke, in the time that dropping funnel inner liquid medicine flows to end, the permeable filter membrane of choke can play the effect that intercepts air, prevents from entering aerofluxus core and below infusion pipeline, finally reaches only liquid function.Due to rejection rate >=99% of this filter membrane to 5 μ m and above granule, can reach the effect of secondary filter medicinal liquid, therefore this transfusion device is without configuring in addition liquid medicine filter, and dual-use material, provides cost savings.
Lead channel on described aerofluxus core sidewall is evenly equipped with three, and the horizontal sextant angle between adjacent lead channel is 120 °.In aerofluxus core, lead channel is uniformly distributed, and can make the uniform liquid that splashes into dropping funnel flow in the infusion pipeline of dropping funnel below, and be conducive to the liquid of the lead channel of flowing through to carry out aerofluxus.
The beneficial effect that the present invention compared with prior art had is:
This transfusion system structure advantages of simple, when use without be inverted or extruding dropping funnel, flow regulator is also without cutting out, easy to operate, air-filtering membrane and exhaust hole can be discharged the air in dropping funnel smoothly, aerofluxus core, liquid outlet and the aerofluxus core lead channel of dropping funnel can prevent the generation of bubble or accumulate, and the gas in the gas-liquid mixture entering in dropping funnel can be discharged; Only the liquid medicine filtering membrane in liquid device stops that the filter effect of liquid is outstanding, liquid dependable performance only, safe and convenient to use, fast reliable.
