From aerofluxus limit liquid level storage liquid transfusion device
Technical field
This utility model relates to disposable use medical apparatus and instruments, especially relates to a kind ofly limitting liquid level storage liquid transfusion device from aerofluxus.
Background technology
The disposable use transfusion bottle and the bag transfusion system of domestic each clinical use of clinical unit of medical institutions; Mainly form by bottle plug puncture unit protective sleeve, bottle plug puncture unit, exhaust hose, air filter, top hose, switch, storage liquid container, middle flexible pipe, latex medicated cap, dropper, dropping funnel, bottom hose, flow regulator, liquid medicine filter and venoclysis needle; Should earlier bottle plug puncture unit be inserted in the infusion vessel in its use, close flow regulator, make storage accept the medicinal liquid of aequum in the liquid container after; Close upper switches; The same with common disposable infusion set again, before the patient not being carried out venipuncture, need to get rid of the transfusion inner air tube.It has two kinds of manual methods usually: the one, bottle plug puncture unit is inserted the transfusion bottle stopper of reversal of the natural order of things after, make dropper get rid of air in the dropping funnel up at lower liquid outlet, treat to charge in the dropping funnel dropping funnel and make it vertically can avoid producing great amount of bubbles after half; Another method is that flow regulator cuts out, pinch press dropping funnel to make it suck about 1/2 to 2/3 place of medicinal liquid to dropping funnel after, slowly open flow regulator, also can avoid producing great amount of bubbles.But these two kinds of methods all will exhaust a lot of times of medical personnel, and are improper as the time having slightly in operation, and medical personnel's a certain amount of medicinal liquid of then will releasing removes to get rid of bubble, brings inconvenience to medical personnel like this.
The utility model content
It is a kind of from aerofluxus limit liquid level storage liquid transfusion device that the purpose of this utility model is to provide; Can in advance a certain amount of medicinal liquid is banished put the storage liquid container in after; Make medicinal liquid descend liquid automatically, get rid of that air bottle makes liquid level stop at certain altitude automatically in the dropping funnel automatically fast; After opening flow regulator, bubble-free medicinal liquid can be got in the infusion tube rapidly, before routine transfusion, need dropping funnel is inverted to get rid of in the dropping funnel air or pinch to press dropping funnel to suck in the medicinal liquid entering dropping funnel and carry out deflated workload thereby reduced medical personnel; Make things convenient for medical personnel easy to operate, save time.
For realizing above-mentioned purpose; This utility model adopts following technical scheme: this utility model is made up of bottle plug puncture unit protective sleeve, bottle plug puncture unit, exhaust hose, air filter, top hose, switch, storage liquid container, middle flexible pipe, latex medicated cap, dropper, dropping funnel, automatic exhauster, 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; Bottle plug puncture unit, exhaust hose, air filter are linked in sequence; Bottle plug puncture unit, top hose, storage liquid container, middle flexible pipe, dropper, dropping funnel, automatic exhauster, bottom hose, liquid medicine filter are linked in sequence; On flexible pipe and the bottom hose, the latex cap sleeve was on the dosing mouth of dropper during switch and flow regulator were placed in respectively, and the needle stand of venoclysis needle is socketed on the conehead of liquid medicine filter; It is characterized in that: the storage liquid container can be transfusion bottle or bag; Automatic exhauster is made up of aerofluxus base, air filtration film and air lock, and dropper and driving fit are inserted in the dropping funnel upper end, and insert from aerofluxus base and driving fit the dropping funnel lower end; The aerofluxus base is respectively equipped with liquid outlet channel and exhaust passage, and the top that the aerofluxus base inserts in the dropping funnel can be made as an inclined-plane; The upper side of liquid outlet channel can be provided with at least one lead channel, the length of lead channel from from dropping funnel inner chamber joint be 0~30mm; The top seal of the exhaust passage of aerofluxus base, the exhaust passage top-side is provided with an air inlet, and the bottom, exhaust passage is provided with a relief area; Exhaust passage bottom is equipped with an air filtration film, and this film has water stop function, can be bonded in the relief area end of bottom, exhaust passage through heat seal, or the end through the extrusion bonded relief area that is provided with in the bottom, exhaust passage of air lock; Bottle plug puncture unit, exhaust hose, the air filter part that is linked in sequence can be replaced by bottle plug puncture unit, air filtration film, air lock; Transfusion bottle top can be provided with a sealing chemicals dosing plant and an exhaust apparatus; Bag top can connect a sealing chemicals dosing plant; Have one can renovate on the air lock, renovated that plug uses preceding place not fill in state in one, transfusion speed is answered in the jam-pack during greater than 50ml/min and is filled in; Has the containing mark line on transfusion bottle and the bag.
This utility model is compared with bag transfusion system with the disposable use transfusion bottle of conventional use clinically, and the liquid outlet place has connected automatic exhauster in the lower end of dropping funnel, and automatic exhauster is made up of aerofluxus base, air filtration film and air lock; The aerofluxus base is respectively equipped with liquid outlet channel and exhaust passage, during use, earlier bottle plug puncture unit is inserted in the infusion vessel; Close flow regulator, make storage accept the medicinal liquid of aequum in the liquid container after, close upper switches; Open the air gag on the automatic exhauster; Owing to the exhaust apparatus on the transfusion bottle with from exhaust joint and atmosphere, and the hydraulic pressure difference in the transfusion bottle, make fast automatic the flowing in the dropping funnel of medicinal liquid in the transfusion bottle; Rising along with liquid level; Medicinal liquid is the air inlet air inlet of the top-side from the exhaust passage of the air in the dropping funnel, through the exhaust passage, air filter film and air lock mouth discharge, and after medicinal liquid rises to the submergence air inlet, gets into exhaust passage to air filtration film; Because of the air filtration film has the effusive function of the water of prevention and can bear certain pressure, liquid level also will no longer rise and rest on aerofluxus base top (being about 2/3 long place of dropping funnel); Medicinal liquid injects only needs 3-5 second in the dropping funnel; After opening flow regulator, the bubble-free medicinal liquid that is temporarily stored in the dropping funnel can enter into rapidly in the infusion tube, and medical personnel need not transfusion device is carried out aerofluxus; Also shortened former evacuation time (former evacuation time needs 20~30 seconds at least); Before routine transfusion, need dropping funnel is inverted to get rid of in the dropping funnel air or pinch to press dropping funnel to suck in the medicinal liquid entering dropping funnel and carry out deflated workload thereby reduced medical personnel, make things convenient for medical personnel easy to operate, save time.
