Abstract
Safety infusion apparatus capable of automatic droplet stoppage relates to medical infusion apparatus, in particular to safety infusion apparatus capable of automatic droplet stoppage. The safety infusion apparatus comprises a bottle cork puncture plug, an upper section infusion tube, a Murphy's dropper, a lower section infusion tube, a regulating switch, a filter and a puncture needle point, wherein, the Murphy's dropper is cone-shaped, the position of the Murphy's dropper descends to the part closer to the puncture needle point, and the lower section infusion tube connected with the outlet end of the Murphy's dropper is smaller in inside diameter than the upper section infusion tube connected with the inlet end of the Murphy's dropper. The utility model not only has the advantages of simple structure, easy realization of production and manufacture, and relatively low manufacturing cost, but also has a good effect of preventing air from entering the lower section infusion tube, thereby guaranteeing the safety of infusion and facilitating the operation of nursing staff at the same time.
Description
Technical field
This utility model relates to a kind of medical Transfusion device, particularly relates to a kind of safe transfusion system of energy automatically drip-stopping.
Background technology
When in hospital, using conventional transfusion device to give patient infusion, after infusion bottle drips sky, if patient is the regulating and controlling switch not, or medical personnel can not in time change liquid, cause medicinal liquid often to drop to below the luxuriant Fei Shi dropper, air in the infusion bottle is entered in the hypomere tube for transfusion with bubble form, all to get rid of the bubble in the hypomere tube for transfusion when causing the nursing staff to change liquid at every turn, and change the air admission hypomere tube for transfusion that can make when infusion bottle is infused once more in the dropper, this not only brings certain trouble to the nursing staff, and bubble is difficult to thoroughly get rid of, remaining air admission human body, might cause the air bound of heart and brain vitals, jeopardize patient's life security.Conventional in addition transfusion device can't stop to infuse automatically, after medicinal liquid is totally lost sometimes, because of the nursing staff has little time nursing or the not discovery of the sleeping back of patient, the phenomenon of a large amount of blood backs will occur.Therefore, conventional transfusion device is not only got rid of bubble to medical personnel and is brought inconvenience in the work, brings potential safety hazard also for transfusion person.Keep certain medicinal liquid and play and prevent air admission hypomere tube for transfusion for making in the luxuriant Fei Shi dropper, many solutions have appearred, as by setting up control valve or optoelectronic induction, magnetic induction control system etc., because these solutions have increased control device, bring the transfusion device complex structure, production cost is higher, makings is difficult, operate problems such as inconvenience.
Summary of the invention
For overcoming above-mentioned deficiency, this utility model purpose provide a kind of simple in structure, just can not make in the luxuriant Fei Shi dropper residual from the just safe transfusion system of automatically drip-stopping of certain medicinal liquid by increasing other control device.
For achieving the above object, this utility model is achieved through the following technical solutions: automatic described in the utility model is stopped safe transfusion system, comprise bottle stopper puncture plug, epimere tube for transfusion, luxuriant Fei Shi dropper, hypomere tube for transfusion, by-pass cock, filter, piercing needle, luxuriant Fei Shi dropper is shaped as taper, its position drops to and puncture needle approaching position on first watch, and the hypomere tube for transfusion internal diameter that is connected with its port of export is less than the internal diameter of the epimere tube for transfusion that is connected with its entrance point.
It is the position of 15-25cm that described luxuriant Fei Shi dropper is positioned at the piercing needle relative altitude, and hypomere tube for transfusion internal diameter is 1.5mm
Compared with prior art, the beneficial effects of the utility model are: the medicinal liquid in infusion bottle is totally lost, when no longer including medicinal liquid and splashing into luxuriant Fei Shi dropper, because luxuriant Fei Shi dropper position drops to the relative altitude of piercing needle and has only 15-25cm, the water column pressure that produces than conventional transfusion device is low, therefore when the medicinal liquid in the luxuriant Fei Shi dropper is reduced to bottom it certain position, water column pressure just with the vein pressure balance of human body, infusion process just can stop automatically, realized not by increasing other control device, just make the residual a certain amount of medicinal liquid of luxuriant Fei Shi dropper just make the infusion process automatically drip-stopping, and owing to the internal diameter of hypomere tube for transfusion dwindles, its sectional area just dwindles, the amount of liquid medicine of depositing just reduces, and is less than remaining amount of liquid medicine in the luxuriant Fei Shi dropper, therefore when the replacing medicine bottle is infused, the remaining air of luxuriant Fei Shi dropper internal upper part can not enter in the hypomere tube for transfusion yet, has reached not allow the good result of the air admission hypomere tube for transfusion in the infusion bottle.Through up to a hundred evidences, about the highest number and minimum number can reach 150 of per minutes and 5-10 respectively and drip during transfusion, suitable with existing transfusion device.Therefore, this utility model is simple in structure, manufacture easy realization, and production cost is lower, and prevents the effective of air admission hypomere tube for transfusion, has both guaranteed transfusion safety, again the convenient nursing personnel operation.
Description of drawings
Fig. 1 is this utility model automatically drip-stopping safe transfusion system structural representation.
Among the figure, 1-infusion bottle, 2-bottle stopper puncture plug, 3-air inlet, 4-epimere tube for transfusion, 5-Murphy type burette, 6-dosing mouth, 7-balance liquid level, 8-hypomere tube for transfusion, 9-by-pass cock, 10-filter, 11-piercing needle.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is done smooth further instruction, but be not limited to embodiment.
Embodiment 1
Below, accompanying drawings working method of the present utility model: use this utility model transfusion device, luxuriant Fei Shi dropper 4 is 20cm with piercing needle 11 relative altitudes, epimere tube for transfusion 4 internal diameters are 3.0mm, identical with existing conventional transfusion device, hypomere tube for transfusion 8 internal diameters are 1.5mm, operational approach is infused routinely, the highest number and minimum number can be controlled at respectively about 150 of per minutes and 5-10 drip during transfusion, medicinal liquid in infusion bottle is totally lost, when no longer including medicinal liquid and splashing into luxuriant Fei Shi dropper, luxuriant Fei Shi dropper 4 original liquid levels slowly drop to when the balance liquid level 7 of its bottom 3.5cm, water column pressure and human vein pressure balance residually just can't continue to descend from the medicinal liquid in luxuriant Fei Shi dropper 4, thereby stop bubble to enter in the hypomere tube for transfusion 8.When infusing again behind the replacing infusion bottle 1, bubble is entered in the hypomere tube for transfusion.
Claims (3)
1. automatically drip-stopping safe transfusion system, comprise bottle stopper puncture plug, epimere tube for transfusion, luxuriant Fei Shi dropper, hypomere tube for transfusion, by-pass cock, filter, piercing needle, it is characterized in that: described luxuriant Fei Shi dropper is shaped as taper, its position drops to and puncture needle approaching position on first watch, and the hypomere tube for transfusion internal diameter that is connected with its port of export is less than the internal diameter of the epimere tube for transfusion that is connected with its entrance point.
