Embodiment Construction

[0018] For details, see figure 1 and figure 2 , a first exemplary embodiment of a dispensing assembly 1 for laparoscopy comprising a double-barreled syringe 2 and a delivery device 3 comprising a delivery unit 4 with a delivery tube 4A attached at one end to The mixer 5 is attached at the other end to the coupling area 6 . Preferably, the mixer is connected to the transfer tube in a non-detachable manner. The transfer unit can be attached to the double-barreled syringe by means of a bayonet ring 7 . Around the coupling area 6 and around the transfer tube 4A there is provided a support 8 which, in the present exemplary embodiment, is formed by a support cap 9 to which the support tube 10 is fastened. Such as figure 1 As shown, the support cap 9 is pushed onto the double barreled syringe and the outlet 11 of the mixer 5 extends beyond the support tube 10 . The double barreled syringe is actuated by a double plunger 12 .

[0019] Alternatively, a double-barreled cartridge ...

Abstract

The dispensing assembly for two components comprises a double syringe and a mixer, a transfer device (3) being interposed between the double syringe (1) and the mixer (5) which is connected to the double syringe and comprises at least two longitudinal channels (14, 15). The transfer device (3) includes a transfer unit (4) with a transfer tube (4A) having a mixer (5) at one end and a coupling area(6) with an inlet portion (18) at the other end, and the coupling area is provided with coupling means (7, 25) which cooperate with coupling means (24) on the double syringe. At least around the coupling area (6) of the transfer unit (4), a support (8) is arranged which is attachable to the double syringe (1). An assembly of this kind allows a simple and economical manufacture of the transfer device and a reliable operation, which is important particularly in laparoscopy as the distance between the dispensing cartridge and the operating field in the abdominal cavity is large in this case.

Description

technical field [0001] The invention relates to a dispensing assembly for at least two liquid components according to the preamble of claim 1 , comprising a double-barreled syringe, a dispensing cartridge or dispensing device and a mixer. Background technique [0002] In most dispensing assemblies, the mixer is secured to the cartridge and the assembly is used in this form. Accessories are often attached to mixers to affect the shape of the mixed components and allow targeted application of materials to desired locations under certain circumstances. However, there are many applications, especially in medical applications, where this simple assembly of a double-barreled syringe, mixer and accessory device is not sufficient. [0003] In medical applications, it is current practice to use two-component adhesives to stop bleeding, seal wounds and sutures, or bond soft tissue. Thus, for example, the application of the dispensing assembly in operations involving the use of an en...
