Description
Technical field
The present invention relates to disposable use medical apparatus and instruments, especially relate to a kind of ability automatic stop liquid transfusion device.
Background technology
The disposable infusion set of domestic each clinical use of clinical unit of medical institutions; Mainly be made up of bottle plug puncture unit protective sleeve, bottle plug puncture unit, air filter, infusion tube, dropper, dropping funnel, flow regulator, liquid medicine filter and venoclysis needle, this product is in clinical use, particularly when medicinal liquid soon drips off; Families of patients is nervous especially; Not noting slightly will to change bottle untimely because of the medicine bottle inner liquid medicine is totally lost, and makes in the bottom hose the air admission dropping funnel under, in order to continue to infuse; The nursing staff can only carry out aerofluxus through twining finger with bottom hose, operation inconvenience very.The automatic stop liquid device is also arranged in the market, but these products are in clinical use, automatic stop liquid effect can not really obtain embodying.
Summary of the invention
The object of the present invention is to provide a kind of disposable use automatic stop liquid transfusion device; Can be in the dropping funnel behind the medicinal liquid during product is being totally lost medicine bottle during no medicinal liquid; Float valve is closing pipe line automatically; The messenger drug fluid power is retained in the bottom hose pipeline always, thereby causes blood back after preventing in the air admission bottom hose, can avoid like this making increase medical personnel working strength because of entering air in managing carries out emptying; Can alleviate the nervous psychology pressure of family numbers of patients nurse again, the medical tangle of avoiding malpractice to cause.
For realizing above-mentioned purpose; The present invention adopts following technical scheme: the present invention includes bottle plug puncture unit protective sleeve, bottle plug puncture unit, air filtration film, air lock, top hose, dropper, latex medicated cap, automatic stop liquid device, go up dropping funnel, following dropping funnel, pressurization bead, bottom hose, flow regulator, liquid medicine filter and venoclysis needle; The bottle plug puncture unit protective sleeve is placed on the bottle plug puncture unit, and air lock is pressed on the air filtration film in the air inlet of bottle plug puncture unit, and bottle plug puncture unit, top hose, dropper, last dropping funnel, following dropping funnel, pressurization bead, bottom hose, liquid medicine filter are linked in sequence; The latex cap sleeve is connected on the dosing mouth of dropper; Flow regulator is placed on the bottom hose, and the needle stand of venoclysis needle is socketed on the conehead of liquid medicine filter, it is characterized in that: the automatic stop liquid device comprises spacing axle sleeve and float valve; Float valve is made up of floating head, floating axle and soft sucker; The automatic stop liquid device is placed in the dropping funnel, and the limit shaft cover is embedded in down dropping funnel inner chamber upper end oral area, and floating axle closely cooperates through cover in spacing axle sleeve center and the floating head; Soft sucker top is embedded in depressed part at the bottom of the floating axle; And receiving spacing axle sleeve spacing, floating head is connected through floating axle with soft sucker, moves up and down at the inner chamber of last dropping funnel and following dropping funnel.
In the float valve, floating head and floating axle are provided with the clearance groove of ventilation, and floating axle and soft sucker also are provided with the clearance groove of ventilation.
Soft sucker in the float valve is that an elastomeric material is processed, and the center is a solid, is a spherical crown shape around the bottom.
Floating head in the float valve can be that PP, PE, PVC, ABS plastic are injection molded, its inner chamber hollow.
Floating axle in the float valve, its top and empty boasting tight fit, it is elongated shaft that the middle part cooperates with spacing axle sleeve, but its underpart is provided with the space of a splendid attire medicinal liquid, and its bottom is provided with the female parts that cooperates with soft sucker.
The spacing axle sleeve of automatic stop liquid device, its center is provided with a collar, is placed on the floating axle, and the collar is fixed in central authorities through plural reinforcement.
The pressurization bead can be that PVC, polyolefin or other elastomeric material are processed.
The present invention compares with the disposable infusion set of conventional use clinically; In use do not have too big difference; Also be bottle plug puncture unit to be inserted the infusion solutions bottle stopper get rid of inner air tube in the transfusion device afterwards; Two kinds of manual methods are arranged: first kind is after bottle plug puncture unit is inserted the transfusion bottle stopper of reversal of the natural order of things, to make dropper get rid of air in the dropping funnel up at lower liquid outlet, treats to charge in the dropping funnel dropping funnel and makes it vertically can avoid producing great amount of bubbles after half; Another method is after bottle plug puncture unit is inserted the transfusion bottle stopper of reversal of the natural order of things, pinch press dropping funnel to make it suck about 1/2 to 2/3 place of medicinal liquid to dropping funnel after, pinch and depress float valve come-up behind the flexible pipe; Medicinal liquid gets into bottom hose, after medicinal liquid is full of pipeline, promptly punctures, infuses after closing actuator; But after medicine bottle and dropping funnel inner liquid medicine are totally lost; Automatic stop liquid device of the present invention can reduce to a certain degree at the dropping funnel inner liquid medicine, and float valve slides to down the dropping funnel liquid outlet under reducing under its buoyancy, makes soft sucker inhale the bottom of infra dropping funnel because of managing interior hydraulic pressure and dirty suction; Thereby closing pipe line solution stopping automatically prevents that the air admission bottom hose from causing blood back; The present invention can reduce medical personnel and get rid of because of getting into the workload of air in managing; Can alleviate the nervous psychology pressure of family numbers of patients nurse again; Thereby make the transfusion safer, so both made things convenient for medical personnel easy to operate, save time, can avoid medical tangle again.
