Definitions

• the present invention relates to an adapter for removing a liquid from a container closed with a stopper or for filling this container, which is closed by means of a stopper fixed by a cap, with at least one partially hollow mandrel on the front, provided with at least one nozzle End for pushing through the plug, a connecting part with an inner cone at the rear end for coupling medical devices and a flat handle element to facilitate the adaptation process in the area between.
• Such adapters or withdrawal cannulas cf. EP 0 499 481 AI and WO 93/24095 are used in the medical field in order, inter alia, to be able to connect commercially available infusion sets to infusion bottles.
• the adapters generally have a lockable taper connection according to DIN 13 090 Part 2.
• the connection of the infusion sets to the infusion bottles is carried out by experienced personnel who have no problems piercing the sealing plugs of the infusion bottles with the adapter and the cutlery on Coupling the adapter.
• An adapter known from WO 95/07066 offers help for placing the disposable syringe on the infusion bottle.
• This adapter is placed on the infusion bottle as a guide for the disposable syringe.
• the cannula of the disposable syringe pierces the closure of the infusion bottle when it is inserted straight into the adapter.
• a patient who is inexperienced in handling syringes or has a motor disorder has trouble not tilting the disposable syringe when it is inserted into the adapter. Tilting will cause the cannula to break. Even if the cannula is correctly inserted into the infusion bottle, the above-mentioned risk of lumping still exists with lyophilisates.
• the present invention is therefore based on the problem of creating an adapter, with the aid of which a liquid can be both taken from a container closed with a stopper and filled into it via a standardized syringe.
• the transfer process should also be able to be carried out quickly, reliably, even by an inexperienced person, without any risk of injury and without great effort. Furthermore, the risk of contamination should be as small as possible.
• the disadvantages known from the prior art are to be avoided.
• the problem is solved in that, on the one hand, a funnel which is open towards the rear end is arranged on the connecting part of the adapter and, on the other hand, an elastic centering and gripping part is seated on the handle element towards the front end of the adapter.
• Wrapping part corresponds at least in some areas approximately to the outer contour of the tuft cap which fixes the stopper on the injection container.
• the front edge of the centering and gripping part extends beyond the mandrel, but the latching elements remain in the area behind the tip of the mandrel.
• the elastic centering and encompassing part is, for example, a thin-walled sleeve that emerges directly from the base element.
• the inside diameter of the sleeve is slightly larger than the outside diameter of the cap attached to the stopper on the infusion bottle.
• Three or four inwardly projecting, individual latching elements are arranged within the sleeve in a plane parallel to the base plate.
• the distance between the base plate and the locking element level is slightly larger than the height of the cap.
• the sleeve itself is extended several millimeters beyond the locking elements. It is a few millimeters longer than the mandrel of the adapter - also to minimize the risk of injury. Consequently, the sleeve centers the adapter when it is placed on the infusion bottle closure.
• individual cantilever arms arranged on the base element can also be used.
• the one-part or multi-part centering and gripping part can also be designed such that it is at least partially plastically deformed after being placed completely on the infusion bottle.
• centering and gripping part can be extended so far that it partially covers the cylindrical outer surface of the corresponding infusion bottle or that the infusion bottle completely disappears therein.
• the entire bottle body serves as a centering aid.
• the infusion bottle can also be equipped with an attached and pre-latched adapter, so that the adapter does not have to be attached and centered when preparing and administering the preparation.
• the connecting part which is arranged on the other side of the grip element and is equipped with an inner cone, enables problem-free coupling of a syringe provided with an outer cone as a connecting part.
• the outer cone of the syringe slides along the inner funnel contour into the standardized inner cone adjoining the funnel.
• the application of a small axial force creates a tight cone connection.
• the syringe forms a unit which is held together by force and form locking and which is stable in any position.
• the unit can only be held on the syringe cylinder. which are brought into the winding position.
• the infusion bottle can be emptied or filled quickly with little effort due to the large bore and nozzle cross-sections in the adapter.
• Each nozzle integrated in the mandrel has a jet direction which deviates from the center line of the adapter by at least 30 °. This prevents the saline solution from hitting the lyophilisate directly when it is injected into the second infusion bottle. It is generally atomized on the inside of the stopper and / or bottle. Depending on the position of the infusion bottle, it flows along or drips down from there. In this way it is prevented that the lyophilizate partially clumps.
• the funnel sits on the grip element in such a way that its upper edge is a distance from the grip element by a length which is approximately 2/3 of the middle, distal index finger width of a male adult according to DIN 33 402 part 2.
• the patient holds the adapter with the infusion bottle positioned underneath in the area between the funnel and the grip element between the index and middle fingers, the mandrel pointing toward the inside of the hand.
• the thumb of the same hand that lies against the bottom of the infusion bottle, he pushes the infusion bottle and the adapter towards one another in a kind of forceps movement.
• This shape means that the patient is not forced to connect the adapter to the infusion bottle by placing the fingers on the sterile funnel.
• the edge design of the grip element and / or the funnel also serves for easier handling. At least one of the parts is flattened in the edge region, for example. After the packaging holding the adapter is sterile, it is prevented from rolling away on a slightly inclined plane.
• the adapter is injection molded from a clear, clear plastic. It preferably consists of one piece. Depending on the intended use, its mandrel can contain a ventilation channel with or without a particle filter.
• an inner cone with a lock e.g. a Luer-Lock inner cone can be integrated.

• Figure 3 Mandrel in front view, shown enlarged, with two cuts.
• Figure 1 shows the adapter in the middle in a side view.
• the adapter is shown enlarged by a factor of two and cut on one side. It is suitable for withdrawing a liquid from a sealed injection bottle according to DIN ISO 8362 Part 1 using a syringe, for example a disposable syringe according to DIN 13098 Part 1 with an outer cone, without an injection cannula.
