Abstract (en)
[origin: WO2022228848A1] A dosing system is intended for adjusting a dosing volume of a flowable medium. The dosing system comprises a dosing syringe (1) which has a syringe body (3) and a dosing plunger (4). A stop device is intended for adjustably limiting a stroke of the dosing plunger (4) in the syringe body (3), which stroke takes place along a central longitudinal axis of the dosing syringe (1). The syringe body (3) has an end-face syringe cone (17) that has a dispensing opening (18) for the medium to be dosed. An external lateral wall of the syringe cone (17) comprises at least one rib (20), which is elevated above a main cone surface of the external lateral wall by a radial rib height. A syringe adapter as a component of a dosing system, comprising a dosing syringe (1) for adjusting a dosing volume of a flowable medium, is intended to connect the dosing syringe (1) to a container for supplying or removing the medium. The syringe adapter has a fluid channel for producing a flow connection between an interior of the container and an interior of the syringe body (3), wherein the fluid channel is delimited by a silicone sleeve portion. An internal diameter of the fluid channel is delimited by a silicone circumferential lip of the sleeve portion. A dosing system results in which the risk of incorrect operation is reduced. The syringe adapter ensures a secure seal of the fluid channel with respect to an external lateral wall of the dosing syringe of the dosing system.
