Abstract
The invention discloses a disposable automatic liquid stopping infusion set which comprises a bottle stopper puncture device protecting sleeve, a bottle stopper puncture device, an air filtering film, an air plug, an upper soft pipe, a drip bucket cover, a latex cap, an upper drip bucket, an automatic liquid stopping device, a lower drip bucket, a lower soft pipe, a flow adjuster, a medicine liquid filter and an intravenous infusion needle. The disposable automatic liquid stopping infusion set is characterized in that the automatic liquid stopping device comprises a floater with a liquid inlet hole and an air discharging hole and a water stopping film piece, the water stopping film piece comprises a frame and a middle thin layer, the water stopping film piece is embedded into the bottom of the floater, the automatic liquid stopping device is arranged in the lower drip bucket, and the automatic liquid stopping device can be filled with medicine liquid and then float. When a small amount of medicine liquid exists in the drip bucket during an infusion process of the automatic liquid stopping device, a liquid outlet of the lower drip bucket is automatically sealed, accordingly, air is prevented from entering the lower soft pipe so that the problem that workload of nursing personnel is increased due to the fact that air enters the lower soft pipe can be avoided, and medical accidents caused by the fact that air enters into the body of a patient can be avoided.
Description
Technical field
The present invention relates to disposable use medical apparatus and instruments, especially relate to a kind of energy self-stopping infusion apparatus.
Background technology
The disposable infusion set of the clinical use of clinical unit of domestic each medical institutions, mainly by protective sleeve for bottle stopper puncture outfit, bottle plug puncture unit, air filter, infusion tube, dropper, dropping funnel, flow regulator, liquid medicine filter and venoclysis needle composition, this product is in clinical use procedure, particularly in the time that medicinal liquid soon drips off, families of patients is nervous especially, slightly do not note being totally lost and changing bottle not in time because of medicine bottle inner liquid medicine, air is entered in the bottom hose under dropping funnel, in order to continue transfusion, nursing staff can only carry out aerofluxus by being wound around finger with bottom hose, operation inconvenience very, or by turning on transfusion needle stand, medicinal liquid is discharged from liquid medicine filter joint, so both wasted medicinal liquid be also easy to pathogenic bacteria invade causing transfusion infect.Though there is in the market self-stopping infusion apparatus, these products are in clinical use procedure, and self-stopping effect can not really be embodied.
Summary of the invention
The object of the present invention is to provide a kind of disposable use self-stopping infusion apparatus, can make product be totally lost after bottle herb liquid, along with dropping funnel inner liquid medicine constantly reduces, when the buoyancy deficiency of medicinal liquid so that self-stopping device while floating, the thin intermediate of sealing diaphragm, be loaded with medicinal liquid under depress, seal the liquid outlet of time dropping funnel, make the medicinal liquid in dropping funnel can not continue to flow down, medicinal liquid in bottom hose is also retained in bottom hose pipeline always, air cannot enter in bottom hose, so just can avoid carrying out the emptying medical personnel's working strength that makes to increase because entering air in managing, can alleviate again the nervous psychology pressure of family numbers of patients nurse, the medical tangle of avoiding malpractice to cause.
For achieving the above object, the present invention adopts following technical scheme: the present invention includes protective sleeve for bottle stopper puncture outfit, bottle plug puncture unit, air-filtering membrane, air lock, top hose, dropping funnel lid, latex cap, upper dropping funnel, self-stopping device, lower dropping funnel, bottom hose, flow regulator, liquid medicine filter and venoclysis needle, protective sleeve for bottle stopper puncture outfit is placed on bottle plug puncture unit, and air lock is pressed on air-filtering membrane in the air inlet of bottle plug puncture unit, bottle plug puncture unit, top hose, dropping funnel lid, upper dropping funnel, lower dropping funnel, bottom hose, liquid medicine filter is linked in sequence, and latex cap sleeve is connected on the dosing mouth of dropping funnel lid, and flow regulator is placed on bottom hose, and the needle stand of venoclysis needle is socketed on the conehead of liquid medicine filter, it is characterized in that: self-stopping device is by with inlet opening, the float of steam vent and sealing diaphragm composition, sealing diaphragm is made up of frame and thin intermediate, and sealing diaphragm embeds the bottom of float, and self-stopping device is placed in lower dropping funnel, and can float being full of after medicinal liquid.
In upper dropping funnel and lower dropping funnel junction, bottom is provided with spline projection.
Dropping funnel lid can be provided with automatic exhauster and also can not arrange, and the air lock on automatic exhauster is pressed on air-filtering membrane in exhaust passage outlet port, or adopts high frequency heat seal air-filtering membrane is heat sealing in exhaust passage outlet port and uses air lock jam-pack.
The bottle plug puncture unit of self-stopping infusion apparatus, air-filtering membrane, air lock, can be also to be substituted by bottle plug puncture unit, exhaust hose, air filter, and bottle plug puncture unit can be plastic-steel pin, can be also plastics pin or two draw point.
