Abstract

An application device for applying a multicomponent tissue adhesive which includes a plurality of supply reservoirs for respectively one fluid component, each supply reservoir having a front end with an opening for discharge of the respective fluid component. The front ends of the supply reservoirs are arranged within accommodating connecting pieces of a connecting headpiece. The accommodating connecting pieces are provided with projections extending radially outwards. The supply reservoirs are held by a holding device. The application device is further provided with a coupling element for releasably connecting the holding device to the connecting headpiece, the coupling element including an encompassing member with a plurality of encompassing zones for at least partially encompassing the accommodating connecting pieces and for abutment on the sides of the projections of the accommodating connecting pieces facing away from the holding device.

Claims

a plurality of supply reservoirs for respective fluid components, each supply reservoir having a front end provided with an opening for discharging the respective fluid components and a rear end disposed opposite to the front end,

a piston arranged for sliding displacement in the supply reservoirs, said piston comprising a piston rod projecting from said rear end and having an actuating end for actuating the piston,

a connecting headpiece having accommodating their front ends for communication with the front ends of the supply reservoirs, the connecting headpiece having separate channels for accommodating;

the individual fluid components

a discharge end disposed at the end of the connecting headpiece for the simultaneous discharge of all fluid components,

a holding device for holding the supply reservoirs in the region of their rear ends and the connecting headpiece in the region of the connecting pieces,

a coupling element for releasably connecting the holding device to the connecting headpiece at one end thereof, said coupling element including an encompassing member which defines a plurality of encompassing zones for at least partially encompassing and engaging the accommodating connecting pieces, and for abutting engagement with the holding device at the other end thereof.

2. The application device according to claim 1, wherein the coupling element comprises a connecting member which is connected at one end to the encompassing member and at the other end to the holding device.

3. The application device according to claim 2, wherein the connecting member is integrally connected at said one end to the encompassing member and said other end is provided with at least one locking projection for locking engagement with the holding device.

4. The application device according to claim 3, wherein the connecting member contains a plurality of locking projections arranged in series along the connecting member.

5. The application device according to claim 3, wherein the holding device contains a locking hole for receiving said other end of said connecting member.

6. The application device according to claim 1, wherein the accommodating connecting pieces of the connecting headpiece are provided with projections which are arranged as annular flanges.

7. The application device according to claim 6, wherein the annular flanges are arranged as male luer lock devices.

8. The application device according to claim 1 wherein the pistons are provided with piston rods which are connected to each other by a common connecting element and thus actuated together.

9. The application device according to claim 8, wherein the common connecting element comprises laterally open receiving spaces adapted to accommodate flanges arranged at the free ends of the piston rods.

10. The application device according to claim 1, wherein the plurality of encompassing zones are elastic to allow lateral mounting on the accommodating connecting pieces.

11. The application device according to claim 1, wherein each encompassing zone comprises a curved elastic bracket extending along an angular range between about 200°

and about 300°

.

12. The application device according to claim 1, wherein the curved elastic bracket is a continuous piece.

13. The application device according to claim 1 wherein the holding device comprises projections extending away from each other and adapted to be gripped by the fingers of a hand, said projections extending out of a plane in which the supply reservoirs held by the holding device are arranged.

14. The application device according to claim 1 wherein the holding device comprises holding receiving portions for pressing and locking the supply reservoirs therein.

15. The application device according to claim 1 wherein the holding device and the supply reservoirs are provided with stopper means for limiting a relative movement of the holding device and the supply reservoirs in the direction of the rear ends of the supply reservoirs.

16. The application device according to claim 1 wherein the supply reservoirs are held by the holding device for slidable displacement therein.

17. The application device according to claim 1 wherein the supply reservoirs have their rear ends provided with projecting flanges for contact with the holding device.

18. The application device according to claim 1 wherein the holding device comprises two mutually connected and symmetrically arranged C-shaped clamps which open away from each other for clamping engagement around two supply reservoirs traversing more than 180°

, said two mutually connected C-shaped clamps containing two projections extending away from each other and along the axis of symmetry of the two C-shaped clamps.
