Abstract: The invention relates to an attachment (10) for a standard injection device (70) for needleless injection of a fluid, having a nozzle adapter (12) and a piston unit (40), wherein the nozzle adapter (12) comprises a skin contact surface (16) arranged on the distal end (14) thereof having an outlet opening (18), a first cylinder section (20) connecting proximally to the outlet opening (18) and a second cylinder section (26) connecting to the first cylinder section (20), and the piston unit (40) is mounted in a movable manner in the first cylinder section (20) to form a piston-cylinder unit and the attachment (10) has a fluid line (48) for transporting fluid from the standard injection device (70) to the outlet opening (18).

Abstract: The invention relates to a system for injecting a fluid through or into the human skin, optionally by needle-free injection or by injection with a needle, with (i) an injection device (110) which includes an ampoule (112) with an ampoule body (114) forming a chamber for receiving the fluid to be injected; an ampoule piston (118) which is axially movable and sealingly guided in the chamber; an outlet (124) disposed at the distant end of the ampoule (112) for the fluid to be injected, wherein the ampoule (112) is rounded in the region of the outlet (124) and the rounded region forms a skin contact surface (126) for the needle-less injection through or into the human skin; and at least one first coupling element (128) of a coupling device which is arranged at the distal end of the ampoule (112) on the ampoule body (114) and configured for sealingly and reversibly attaching a needle attachment (150), and (ii) a needle attachment (150) with a cannula part (152) comprising a needle (156); and an adapter part

Abstract: The invention relates to a system for injecting a fluid through or into human skin, optionally by needle-free injection or by injection with a needle, comprising (A) a single-use syringe (10) comprising an ampule body (12) forming a chamber for accommodating the fluid to be injected, arranged within the chamber, an axially displaceable, sealingly guided ampule piston (16) and an external taper (18) of a Luer cone at the distal end of the ampule body (12); (B) an adaptor (30) comprising an internal taper (32) of a Luer cone at the proximal end of the adaptor (30) and an exit aperture (36) for the fluid to be injected needle-free at the distal end of the adaptor (30) and (C) an autoinjector comprising a receptacle device (50) for the coupled and fluid-filled combination of a single-use syringe (10) and an adaptor (30), which is configured to maintain the form-fit between the single-use syringe (10) and the adaptor (30) and to support the ampule body (12) of the single-use syringe (10), distally arranged a sk

Abstract: The invention relates to an injection device, especially for a device for injecting an injectable product. Said device comprises a reservoir (12) for receiving the product, a first outlet arrangement (14) comprising a needle and used to transfer the product from the reservoir (12) to the injection site, and an actuating device (16) for applying a pressure (P) to the product in the reservoir (12), the actuating device (16) comprising a second, needleless outlet arrangement (44, 54) for transferring the product from the reservoir (12) to the injection site or being arranged against the second needleless outlet arrangement (46, 56) in a replaceable manner.

Abstract: An injection channel is produced in human or animal tissue by means of a pre-injection device for incorporating a medium which is to be injected. Said pre-injection device comprises a chamber which is used to receive a pre-injection medium, a nozzle which is provided for attachment to the skin and a pressure generating device which acts on the chamber in order to generate a high-pressure jet from the pre-injection medium exiting from the nozzle. Said type of needle-free pre-injection device is serially connected to a main injection device.
