Embodiment Construction

[0015] A first exemplary embodiment of the device according to the invention comprises a first and a second double dispensing device, hereinafter denoted double syringe 1 and double syringe 2 each having two storage containers 5 , 6 and 7 , 8 . This double syringe comprises double push rod 9 and 10 and plunger 11 and 12 that are arranged on the push rod respectively (see Figures 2 to 5 ), and is closed by closing caps 13 and 14 (see figure 2 and 3).

[0016] The aforementioned dual syringes are commercially available. The gist of the device of the invention is to transfer the contents of one dual syringe into another dual syringe and subsequently dispense via a mixer or attachment such as a tip or the like, or to transfer the contents of a dual syringe to a mixing common adapter on the device or accessory. The connection between the two double syringes is ensured by means of the transfer unit which according to this embodiment provides the above described transfer means. ...

Abstract

The arrangement for transferring, mixing, and dispensing preferably comprises at least two dispensing devices ( 1, 2 ). One of said dispensing devices ( 2 ) comprises liquid components ( 21, 23 ) and the arrangement comprises a transfer unit ( 15 ) for the connection of said dispensing devices ( 1, 2 ), and said transfer unit comprises connecting channels ( 36, 38 ) between outlets ( 17, 18; 41, 42 ) for the components ( 21, 23; 22, 24 ) in the storage containers ( 5, 6; 7, 8 ) of said dispensing devices ( 1, 2 ). For an increased reliability of operation, said transfer unit ( 15, 31, 39 ) comprises locking members ( 36 ) for receiving corresponding flanges ( 19, 20 ) provided on said dispensing devices ( 1, 2 ). A syringe system of this kind, using double syringes, allows an unproblematic storage and an easy and thorough mixing of multiple components as well as a simple dispensing of the mixtures. An arrangement of this kind offers particular advantages when the first syringe contains a powder or granulate, e.g. bone cement or a bone replacement material.

Description

technical field [0001] The present invention relates to a device and method for conveying, mixing and dispensing components comprising at least two dispensing devices. Background technique [0002] A device of this type is known from EP-0 292 472, which discloses a device for preparing and applying tissue adhesives, in which four syringe bodies are joined in pairs by a joint to form a corresponding unit . The adapter includes a corresponding cone for receiving a corresponding conical portion on the syringe, but such a conical connection is not sufficient for higher pressure and high safety applications. Furthermore, this reference only discloses the connection between two opposing or adjacent syringes, respectively. [0003] In some applications, as many as four or more components need to be mixed and dispensed, and these components may be liquid and powdered, granular or porous. Typically, these components are stored separately and mixed by shaking, agitation, and / or wit...
