Abstract
The utility model discloses a self-exhaust non-bubble infusion apparatus, which comprises a protecting jacket for a bottle stopper puncture apparatus, the bottle stopper puncture apparatus, an air filter, an infusion hose, a dropping tube, a dropping hopper, a flow regulator, a liquid medicine filter and an intravenous infusion needle which are connected sequentially. A self-exhaust connector is arranged at a liquid outlet at the lower end of the dropping hopper. The self-exhaust connector comprises an exhaust base. A liquid outlet channel and an exhaust channel are arranged on the exhaust base. The upper end of the dropping hopper is inserted into the dropping tube and closed tightly, and the lower end of the dropping hopper is inserted into the exhaust base and closed tightly. After the bottle stopper puncture apparatus is inserted into a large infusion bottle stopper, the self-exhaust non-bubble infusion apparatus can quickly and automatically drop the liquid, automatically controls the height of the liquid level in the dropping hopper and automatically removes the air in the dropping hopper. After the flow regulator is opened, the self-exhaust non-bubble infusion apparatus enables the liquid medicine without air bubbles to quickly enter the infusion hose, so as to reduce the working load of medical staffs who need to invert the dropping hopper to remove the air in the dropping hopper or pinch and press the dropping hopper to suck the liquid medicine into the dropping hopper and to exhaust the air before the conventional infusion.
Description
Technical field
This utility model relates to disposable use medical apparatus and instruments, especially relate to a kind of can be from the aerofluxus bubble-free infusion set.
Background technology
The disposable infusion set of domestic each clinical use of clinical unit of medical institutions; mainly form by 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; 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 a large amount of bubbles after half; Other method is that flow regulator cuts out, and pinches and presses dropping funnel to make it suck medicinal liquid to about 1/2 to 2/3 place of dropping funnel, slowly opens flow regulator, also can avoid producing a large 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
The purpose of this utility model is to solve and has the problems referred to above in the prior art, provide a kind of from the aerofluxus bubble-free infusion set, can be after bottle plug puncture unit is inserted the infusion solutions bottle stopper fast automatic liquid down, automatically control liquid level in the dropping funnel, automatically get rid of air in the dropping funnel, after opening flow regulator, bubble-free medicinal liquid can be entered rapidly in the infusion tube, thereby having reduced medical personnel needs dropping funnel is inverted to get rid of in the dropping funnel air or pinch before routine transfusion to press dropping funnel suction medicinal liquid to enter in the dropping funnel and carry out deflated workload, make things convenient for medical personnel easy to operate, save time.
For achieving the above object, the technical solution adopted in the utility model is as follows:
Of the present utility model from the aerofluxus bubble-free infusion set; comprise 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 composition; it is characterized in that: the liquid outlet place is provided with from exhaust joint in the dropping funnel lower end; comprise the aerofluxus base from exhaust joint; the aerofluxus base is provided with liquid outlet channel and exhaust passage; 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 bottom, exhaust passage of described aerofluxus base is provided with a relief area, is provided with the air filtration film with water stop function in the relief area bottom, and the exhaust passage end is provided with air lock.
The top seal of the exhaust passage of described aerofluxus base, the exhaust passage top-side is provided with an air inlet.
The upper side of described liquid outlet channel is provided with at least one lead channel, and the width of lead channel is 0.4mm
~0.7mm, the length of lead channel from from dropping funnel inner chamber joint be 0
~30mm, the aperture of liquid outlet is 1.2mm
~2.5mm.
The top that described aerofluxus base inserts in the dropping funnel is provided with the inclined-plane.
Described air lock is provided with to be renovated, and has renovated plug in.Use preceding place not fill in state, transfusion speed is answered in the jam-pack during greater than 50ml/min and is filled in.
Described filter membrane is bonded in the relief area end by heat seal, or extrusion bonded in the relief area end by air lock (13).
This utility model is compared at liquid outlet place, the lower end of dropping funnel with the conventional disposable infusion set that uses clinically and has been connected from exhaust joint, from exhaust joint by the aerofluxus base, air filtration film and air lock are formed, the aerofluxus base is respectively equipped with liquid outlet channel and exhaust passage, before being inserted the infusion solutions bottle stopper, bottle plug puncture unit closes flow regulator, after inserting infusion bottle, communicate with atmosphere owing to the air inlet on the bottle plug puncture unit with from exhaust joint, and the hydraulic pressure difference in the infusion bottle, make fast automatic the flowing in the dropping funnel of medicinal liquid in the infusion bottle, rising along with liquid level, medicinal liquid is automatically with the air inlet air inlet of the air in the dropping funnel from the exhaust passage top-side, through the exhaust passage, air filter film and air lock mouth are discharged, after rising to the submergence air inlet, medicinal liquid enters the exhaust passage to the 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 (1/2 place that dropping funnel is long); 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, medical personnel need not transfusion device is carried out aerofluxus, also shortened former evacuation time (former evacuation time needs more than 30 seconds at least), thereby having reduced medical personnel needs dropping funnel is inverted to get rid of in the dropping funnel air or pinch before routine transfusion to press dropping funnel suction medicinal liquid to enter in the dropping funnel and carry out deflated workload, make things convenient for medical personnel easy to operate, save time.
