Abstract
The utility model discloses a kind of burette type transfusion apparatus, comprise bottle plug puncture unit, transfusion bottle body, dropping funnel, flow regulator, venoclysis needle, therebetween by hose connection integral, be provided with automatic exhaust device in described dropping funnel, the flexible pipe between described flow regulator and venoclysis needle is provided with precision liquid medicine filter.This utility model has automatic vent, automatic liquid-stopping, secondary filter function, its reasonable in design material safety, is mainly used in the occasion of infantile infusion and the accurate infusion monitoring dosage of needs.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to burette type transfusion apparatus.
Background technology
At present, there is following defect in the burette type transfusion apparatus used clinically: (1) automatic liquid-stopping function is that the buoy placing a rubber like pad in transfusion bottle body stops liquid device, by buoy by medicinal liquid buoyancy impact blocking tube for transfusion reach automatic liquid-stopping effect, only to be subject to the impact of medicine liquid ingredient and degree of purity larger for liquid function, slightly impurity, granule, plastic buoy just cannot coincide with tube for transfusion, can not realize automatic liquid-stopping.The medicinal liquid being blocked in transfusion device tens of milliliters after automatic liquid-stopping below buoy cannot continue to input human body, there is the problem of the loss of medicinal liquid.
(2) adopt common drug liquid filter (>=15 μm) to patient fluid infusion, a large amount of particulate matters (carbon granule, antibacterial, fat embolus, rubber, plastics etc.) is there is in medicinal liquid, these particulate matters are after transfusion enters human body, potential and long-term harm (reaction of phlebitis, thromboembolism, tissue necrosis, granuloma, pyrogen sample, anaphylaxis) can be produced to human body, sometimes even directly injure life.
(3) material all adopts the harmful PVC material containing DEHP plasticizer.DEHP plasticizer, not only in depositing or using, can infiltrate in blood, have and cause hepatic lesions, affects the risk to male genetic and sperm development; Remain a small amount of Vinyl Chloride Monomer in Corvic, the Vinyl Chloride Monomer of minute quantity can be produced in the course of processing.And Vinyl Chloride Monomer is proved to be and can causes wrist, finger edema, skin sclerosis, the even symptom such as chloracne, splenomegaly and hepatic injury.Discarded polrvinyl chloride medical apparatus and instruments burning can produce hydrogen chloride with bioxin toxic gas, buries and does not degrade, also can contaminated soil and subsoil water.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of non-PVC burette type transfusion apparatus with automatic vent, automatic liquid-stopping, secondary filter function, its occasion being mainly used in infantile infusion and needing accurate infusion monitoring dosage.
To achieve these goals, the technical solution adopted in the utility model is: burette type transfusion apparatus, comprise bottle plug puncture unit, transfusion bottle body, dropping funnel, flow regulator, venoclysis needle, therebetween by hose connection integral, be provided with automatic exhaust device in described dropping funnel, the flexible pipe between described flow regulator and venoclysis needle is provided with precision liquid medicine filter.
Described automatic exhaust device is elongated cylinder, has three inlets, and top is provided with a small cap.
The auto-stopping liquid film of described precision liquid medicine filter is asymmetric micropore filtering film, aperture≤5 μm.
Described perforator adopts ABS material.
Described transfusion bottle body adopts PETG material.
Described flexible pipe, dropping funnel, liquid medicine filter adopt TPE material.
The labor intensity that this utility model burette type transfusion apparatus has automatic vent, automatic liquid-stopping function can alleviate medical personnel, improves the safety of transfusion simultaneously.Automatic exhaust device of the present utility model is the principle of applied fluid mechanics surface tension of liquid, by controlling infusion channel gap value, utilize the surface tension of liquid in gap, reach automatic ventilating function, be in use inverted dropping funnel without the need to extruding or choke the pipeline operation of dropping funnel lower end.Adopt precision liquid medicine filter to realize filtering and the double effects stopping liquid, after automatic liquid-stopping, by extruding dropping funnel gently, can be totally lost remaining in transfusion device medicinal liquid, avoiding the loss of medicinal liquid, effective guarantee therapeutic effect.
Accompanying drawing explanation
Fig. 1 this utility model structural representation;
The structural representation of Fig. 2 automatic exhaust device of the present utility model.
Detailed description of the invention
Burette type transfusion apparatus of the present utility model, is mainly comprised bottle plug puncture unit 1, transfusion bottle body 5, dropping funnel 8, flow regulator 11, venoclysis needle 14, is linked into an integrated entity therebetween by flexible pipe 10.Flexible pipe between flow regulator 11 and venoclysis needle 14 is provided with precision liquid medicine filter 12.The film that precision liquid medicine filter uses is asymmetric micropore filtering film, aperture≤5 μm, has and filters and the double effects of only liquid.
Transfusion bottle body 5 top, bottom are respectively arranged with transfusion bottle upper cover 3 and transfusion bottle lower cover 6, and micropipette 7 is stretched in dropping funnel 8 by drop lower cover 6.Dropping funnel 8 bottom automatic exhaust device 9 is housed.Automatic exhaust device 9 is elongated cylinder, has three inlets 92, and top is provided with a small cap 91.
During use, bottle plug puncture unit 1 and exhaust needle are vertically inserted reversal of the natural order of things infusion bottle rubber plug central authorities, make exhaustor upwards; Close flow regulator 11, medicinal liquid flows into transfusion bottle body 5 at once, when observation medicinal liquid flow to institute's expense, closes transfusion bottle body upper end-fixture 2; Open flow regulator 11, without the need to extruding or inversion dropping funnel, also without the need to medical personnel carry out bomb tube, volume (around) pipe, after medicinal liquid flows into dropping funnel 1/3-1/2 place automatically, drip speed by slowly to very fast, be full of whole pipeline gradually, until when overflowing from scalp acupuncture needle point, automatic emptying inner air tube, completes bleeding.
Require routinely to carry out venipuncture, adjust flux as required.Treat that transfusion terminates, medicinal liquid flow to liquid medicine filter place, automatically stops, and completes automatic liquid-stopping.If needed, after automatic liquid-stopping, by extruding dropping funnel gently, can be totally lost remaining in transfusion device medicinal liquid, avoiding liquid waste.
