Abstract: An auto-injector for administering a dose of a liquid medicament (M) is present having a tubular chassis telescopable in a tubular case, a carrier subassembly comprising a tubular carrier slidably arranged relative to the chassis inside the case, where the carrier is adapted to contain a syringe with a hollow injection needle. The injector also has a drive spring and a plunger for forwarding load of the drive spring to a stopper of the syringe, wherein the syringe is lockable for joint axial translation with the carrier. A control spring is arranged around the carrier for translating the carrier in a proximal direction (P) for insertion of the needle through the chassis into an injection site.

Abstract: A microfluidic separation system for separating fluid sample medium from cells provided in a sample, for example, a sample of bodily fluid which is to be subjected to further analysis. The system may include a microfluidic structure and a cell aggregation agent. The microfluidic structure may include one or more microfluidic channels operable to separate aggregated cells from fluid sample medium by size exclusion.
