Description
Technical field
The present invention relates to a kind of medicine instrument, relate in particular to a kind of transfusion device.
Background technology
Existing transfusion device generally comprises bottle plug puncture unit, dropping funnel and infusion tube, forms bubble easily in dropping funnel and infusion tube during use, so the nurse need get rid of the operation of bubble, has increased the time of operation like this.Chinese patent (patent No.: ZL032054599) propose bubble-proof transfusion device, the change bubble of dropping funnel position can not enter downcomer behind the interior unnecessary gas of this transfusion device eliminating dropping funnel, is applicable to the non-gravity transfusion device, but still manually aerofluxus when beginning to operate.
Chinese invention patent application (application number is 200610146971.2) discloses a kind of automatically exhausting self-destruction type infusion device of being made up of bottle plug puncture unit, conduit and dropping funnel, it is characterized in that having in the dropping funnel exhaustor, its lower end and downcomer are connected, the upper end tilts, when medicinal liquid injects dropping funnel with dropping funnel in unnecessary gas discharge from the influencing meridian exhaustor.When surpassing the infusion hole of exhaustor, the liquid level of medicinal liquid flows into downcomer from infusion hole.Before medicinal liquid flows into downcomer with dropping funnel in unnecessary gas discharge, do not form bubble, reach automatic vent.Debris in the dropping funnel below the infusion hole can not be discharged, and can't clean, and is unrenewable, reaches self-destruction.Tilt because the exhaustor of above-mentioned patent need be made the upper end, all have difficulties at mold with when exhaustor is installed like this.
Summary of the invention
When using, existing transfusion device needs the artificial technological deficiency of getting rid of bubble in order to solve.The purpose of this invention is to provide a kind of automatic-exhaust transfusion device, it has solved the technical problem that the transfusion device bubble produces effectively, has characteristics simple in structure, easy to use.
In order to realize above-mentioned technical purpose, the present invention has adopted following technical scheme:
Automatic-exhaust transfusion device, this transfusion device comprises bottle plug puncture unit, flow control valve, dropping funnel, last infusion tube and following infusion tube, last infusion tube is communicated with bottle plug puncture unit, flow control valve is arranged on down on the infusion tube, the inlet of dropping funnel and liquid outlet are communicated with infusion tube and following infusion tube respectively, cover is equipped with down connection tube on the liquid outlet of dropping funnel, the lower end of following connection tube connects described infusion tube down, following connection tube upper end extends upward the formation exhaustor, be provided with axially extending bore in the described exhaustor, axially extending bore is conducted with following infusion tube, and axially is provided with the drain slit that is conducted with axially extending bore at the perisporium of exhaustor.
Anti-bubble of the present invention produces principle and is: after liquid entered dropping funnel, because liquid has surface tension, the pressure of liquid can't overcome the surface tension that liquid forms in the drain slit during beginning, and liquid can not enter axially extending bore; Drip step by step at liquid, liquid-immersed drain slit, simultaneously the atmospheric pressure of dropping funnel increases, and when the pressure sum of atmospheric pressure and liquid made pressure overcome the surface tension that liquid forms in the drain slit, liquid was broken through the slit and is entered axially extending bore, carries out drain.At this moment, owing to passed through a period of time, the bubble of output floats when dropping liquid, and the liquid that enters the bottom of axially extending bore does not have bubble, can prevent effectively that bubble from producing.
As preferably, above-mentioned drain slit is 1 or 2 or 3 or 4.Generally speaking, the drain slit can increase cost of processing more than 4, causes the intensity of exhaustor to reduce simultaneously.
As preferably, the upper end closed of above-mentioned axially extending bore.The upper end closed of axially extending bore can be prevented that liquid from directly splashing in the axially extending bore.
As preferably, the length in above-mentioned drain slit is 0.5cm～3.0cm.The length in drain slit is very crucial, and length is too short, and when then overcoming surface tension, amount of liquid is few in the dropper, can't make bubble have enough come-up distances; Length is long, and the fluid drips that increases submergence drain slit adds the time.
As preferably, the width in above-mentioned drain slit is 0.2～1.5mm.
As preferably, the thickness of the perisporium of above-mentioned exhaustor is 0.5～1.5mm.
As preferably, above-mentioned drain slit is 3 or 4, and 3 or 4 drain slits evenly are arranged on the perisporium of exhaustor, the upper end closed of axially extending bore.With the upper end closed of axially extending bore, prevent that liquid from directly splashing in the axially extending bore on the one hand; Increase the intensity of exhaustor on the other hand.
As preferably, the inlet of above-mentioned dropping funnel is provided with connection tube, describedly goes up the upper end that infusion tube is connected connection tube, and last connection tube extends to form drain pipe downwards, and the bottom lock of drain pipe is provided with liquid outlet at the sidewall of drain pipe.When above-mentioned structure made the liquid immersion, beginning most was to flow down from liquid pipe sidewall, and can avoid owing to beginning is exactly to drip to produce bubble.
As preferably, above-mentioned drain slit is 1, and liquid outlet is 1, and drain slit and liquid outlet are separately positioned on both sides.Said structure, structure are the simplest, can prevent again simultaneously in the direct axially extending bore of liquid on the liquid outlet.
As preferably, above-mentioned following connection tube and last connection tube are respectively rigid plastics.Adopt rigid plastics, be convenient to processing and assembling.
The present invention is owing to adopted above-mentioned technical scheme, compare with 200610146971.2, realized same function, can solve technical problem and self-destruction that the transfusion device bubble produces effectively, but structure is more simple, it is more convenient to use, and the present invention has application value widely.
