Abstract
The utility model relates to an aseptic medical apparatus, in particular to a transfusion system which is easy to discharge bubbles. The transfusion system comprises a protecting sleeve of a cork puncture outfit, a cork puncture outfit, a short transfusion pipe, an air filter, an upper burette, a dropping funnel, a flow governor, a long transfusion pipe, a liquid medicine filter and a disposable intravenous infusion needle, wherein the lower end of the dropping funnel is provided with a lower burette, the top of the upper end of the lower burette is closed, the lateral walls of the circumambience of the lower burette are provided with two or more than two liquid inlets communicated with the later walls, the upper end of the lower burette upwards extends into the dropping funnel, and a liquid outlet positioned on the lower end of the lower burette is downwardly sleeved into the long transfusion pipe with the flow governor. Compared with the prior art, the utility model has the advantages of easy bubble discharge, simple structure, safety, reliability and easy processing, can prevent bubbles generating and entering and can be widely used for clinic.
Description
Technical field
This utility model relates to aseptic medical equipment, especially relates to a kind of easy aerofluxus bubble infusion device.
Background technology
At present, the general infusion set that medical field is used always is by bottle plug puncture unit, last dropper, dropping funnel, transfusion catheter, flow regulator, parts such as liquid medicine filter and venoclysis needle constitute, general infusion set just begins in transfusion, when medicinal liquid enters dropping funnel, liquid is easily discharged the gas in the dropping funnel downwards the formation gas-liquid mixture and is entered down in the transfusion catheter, therefore produce bubble, simultaneously, surface tension effects because of the transfusion catheter inwall, the inwall of transfusion catheter is a spot of bubble of absorption easily, and get rid of comparatively difficulty of consequent bubble process, time-consuming and loaded down with trivial details, if the bubble that is produced enters in patient's body, easily cause harm such as aeroembolism.So, medical personnel must be with the emptying as much as possible of the bubble in the catheter of transfusion system before infusing, and common artificial deflated method is: after bottle plug puncture unit is inserted transfusion bottle stopper, earlier squeeze dropping funnel with hands, medicinal liquid is entered in the dropping funnel, simultaneously with dropping funnel reversal of the natural order of things, treat that certain amount of fluid is full of dropping funnel after, put down dropping funnel, just most bubble may be got rid of, the process of this artificial aerofluxus bubble is loaded down with trivial details time-consuming again, is unfavorable for promptly infusing and giving emergency treatment to a patient.
Summary of the invention
The purpose of this utility model be to provide a kind of in infusion process, can effectively prevent bubble produce and prevent a large amount of bubbles enter in the transfusion catheter and easy emptying attached to a small amount of bubble on the transfusion catheter inwall, simple in structure, safe and reliable transfusion device.
The purpose of this utility model is achieved in that this utility model comprises bottle plug puncture unit protective sleeve, bottle plug puncture unit, transfusion tubulature, aerofluxus tubulature, air filter, goes up dropper, dropping funnel, following dropper, flow regulator, transfusion long duct, liquid medicine filter and disposable use venoclysis needle; feature is that dropper down is installed in the dropping funnel lower end; the upper end of following dropper upwards stretches in the dropping funnel, and the liquid outlet of following dropper lower end is enclosed within downwards in the transfusion long duct that has flow regulator.
The upper end top seal of following dropper, sidewall has two or more inlet openings that connects sidewall all around, and the shape of inlet opening can be a kind of in ring-type strip or ellipse or the circle, these inlet openings can effectively prevent the generation of bubble and prevent that a large amount of bubbles from entering in the transfusion long duct, and easy emptying is attached to a small amount of bubble on the transfusion catheter inwall.
This utility model since on the basis of traditional disposable infusion set, set up have the generation that can prevent bubble and prevent a large amount of bubbles enter in the transfusion long duct and easy emptying attached to the following dropper of a small amount of bubble on the transfusion catheter inwall.This utility model is the same with the transfusion set operating process in use, does not increase operating procedure, can save the loaded down with trivial details process of artificial aerofluxus bubble; When this utility model uses, after bottle plug puncture unit inserted transfusion bottle stopper, earlier squeeze dropping funnel with hands, medicinal liquid is entered in the dropping funnel, need not hang upside down dropping funnel, when medicinal liquid enters in the dropping funnel, and when covering inlet opening to the dropper upper end sidewall down gradually, the air and the bubble of sneaking in the medicinal liquid will upwards be discharged, and a large amount of bubbles can not resemble the general infusion set sample and directly enter in the transfusion long duct, thereby prevent that effectively bubble from producing; Simultaneously, the medicinal liquid liquid outlet that can waltz through down dropper enters the transfusion long duct that has flow regulator; Easily, can easily a small amount of bubble be got rid of, get final product normal infusion by the mode of flicking the transfusion catheter outer wall attached to a small amount of bubble on the transfusion catheter inwall.This utility model can solve existing transfusion device infusion process because of aerofluxus bubble work loaded down with trivial details, lose time, lack safety guarantee, healthcare givers or patient and family members' mental burden heavily waits problem, thereby effectively reduce medical personnel's working strength, reduce liquid waste, remove the patient and in infusion process, enter the worry that human body causes adverse consequencess such as aeroembolism because of gas.
This utility model compared with prior art has following advantage:
1, can prevent that in infusion process bubble from producing and prevent that bubble from entering, easily aerofluxus bubble, processing simple in structure, safe and reliable, easy;
2, can extensive use clinical.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the generalized section of following dropper.
The specific embodiment
Below in conjunction with embodiment and contrast accompanying drawing this utility model is described in further detail.
This utility model comprises bottle plug puncture unit protective sleeve 1, bottle plug puncture unit 2, transfusion tubulature 3, aerofluxus tubulature 4, air filter 5, goes up dropper 6, dropping funnel 7, flow regulator 9, transfusion long duct 10, liquid medicine filter 11 and disposable use venoclysis needle 12, and dropper 8 down is installed in dropping funnel 7 lower ends.
Sidewall has two or more and connects the inlet opening 13 of dropper 8 sidewalls down around infra dropper 8 upper ends, and the shape of inlet opening 13 can be a kind of in ring-type strip or ellipse or the circle, and there is liquid outlet 14 lower end of following dropper 8.
