Description
Technical field
This utility model relates to a kind of from aerofluxus Anti-bubble secondary filter automatic liquid-stopping transfusion apparatus, belongs to medical instruments field.
Background technology
Transfusion is widely used Therapeutic Method in clinical treatment, and safety is the indispensable essential condition of transfusion.
When 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, when transfusion, infuse after the bubble in transfusion catheter must being discharged completely again.Conventionally the method adopting is, bottle plug puncture unit is being thrust after transfusion bottle stopper, be inverted or extruding dropping funnel, medicinal liquid is entered in dropping funnel, in dropping funnel, be filled with half left and right liquid after rapidly dropping funnel is returned to normal operating condition again, 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, to medical personnel, brings great inconvenience.
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, during common clinical transfusion, need patient and medical personnel constantly to close injecting medical liquid surplus, taken very large energy, also patient is caused to larger mental pressure simultaneously, through the medicinal liquid of being everlasting, remain when more and just call medical personnel, easily cause doctor-patient relationship contradiction, be unfavorable for the carrying out of Rehabilitation and normal medical and nursing work.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of simple in structure, easy to use and safe from aerofluxus Anti-bubble secondary filter automatic liquid-stopping transfusion apparatus.
Described in the utility model from aerofluxus Anti-bubble secondary filter automatic liquid-stopping transfusion apparatus, comprise bottle plug puncture unit, infusion pipeline, dropping funnel, flow regulator, cone joint and venoclysis needle, the drain pipe place of dropping funnel bottom arranges Anti-bubble structure, the inner side of dropping funnel bottom arranges automatic exhauster, automatic exhauster 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 secondary filter automatic liquid-stopping device.
Described Anti-bubble structure is the hole enlargement transition region that is positioned at the drain pipe port of export, 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 from forming bubble herein because the areal pressure difference of the surface tension difference with medicinal liquid, delivery position accumulates in, get rid of bubble and with medicinal liquid, enter the hidden danger of dropping funnel below infusion pipeline, use safety, and without being inverted dropping funnel, easy to operate while using.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.
