The needle (3) comprises a hollow needle body (4) to guide the fluid. The needle body (4) is furthermore formed such that an inlet section (20) of the needle body (4) defines a first flow direction for the fluid and an outlet section (21) of the needle body (4) defines a second flow direction for the fluid, wherein the first flow direction is inclined with respect to the second flow direction. ## Claims ### Claim 1 An assembly comprising: a needle for administering a fluid, the needle comprising: a hollow needle body configured to guide the fluid, the needle body being formed such that an inlet section of the needle body defines a first flow direction for the fluid, and an outlet section of the needle body defines a second flow direction for the fluid, wherein the first flow direction is inclined with respect to the second flow direction, and wherein the needle body comprises a bend which connects the inlet section and the outlet section; a needle unit comprising the needle, the needle being fixed to a needle hub, wherein the needle unit further comprises a needle housing which covers a part of the bend of the needle body, a reservoir retaining fluid, wherein the needle is fluidly connected to the reservoir, and an assembly housing, wherein the needle unit is rotatably mounted to the assembly housing such that the needle hub is axially secured but rotatable with respect to the assembly housing, the needle unit being rotatable relative to the assembly housing such that a longitudinal axis of the outlet section of the needle body points toward a dose member. ### Claim 2 (depends on 1) The assembly according to claim 1, wherein the needle body is formed such that the first flow direction and the second flow direction are right-angled. ### Claim 3 (depends on 1) The assembly according to claim 1, wherein the needle hub is rotatable around the first flow direction. ### Claim 4 (depends on 1) The assembly according to claim 1, wherein the assembly housing comprises: a first housing part; and a second housing part, wherein the needle is secured to the first housing part, wherein the assembly comprises a drive mechanism, and wherein the assembly is configured such that the first housing part is movable in a first direction relative to the second housing part to activate the drive mechanism to dispense fluid through the needle. ### Claim 5 (depends on 4) The assembly according to claim 4, wherein the first housing part and the second housing part are pivotally connected to each other, and wherein the first housing part is spring-biased away from the second housing part or vice versa. ### Claim 6 (depends on 4) The assembly according to claim 4, wherein the second housing part comprises an opening, and wherein the assembly is configured such that, by a movement of the first housing part with respect to the second housing part, the needle is at least partly movable through the opening such that the outlet section of the needle body protrudes through the opening from the assembly housing. ### Claim 7 (depends on 6) The assembly according to claim 6, wherein the first housing part retains the drive mechanism, and wherein the assembly is configured such that, as soon as the outlet section protrudes a certain distance through the opening during movement of the first housing part with respect to the second housing part, fluid is administered through the needle. ### Claim 8 (depends on 6) The assembly according to claim 6, wherein the second housing part comprises a contact area for contacting a surface into which the fluid is to be administered, and wherein the opening is provided in the region of the contact area. ### Claim 9 (depends on 4) The assembly according to claim 4, wherein the second housing part comprises a shield configured to prevent or hinder the outlet section of the needle from being visible for a user. ### Claim 10 (depends on 4) The assembly according to claim 4, wherein the assembly is configured such that the first housing part is movable in a second direction, relative to the second housing part to deactivate the drive mechanism to stop dispense of fluid through the needle, wherein the second direction is opposite the first direction. ### Claim 11 (depends on 1) The assembly according to claim 1, wherein the needle is rotatable from an administration position to a storage position, and wherein the assembly is configured such that, when the needle is in the storage position, the needle is prevented from being visible for a user. ### Claim 12 (depends on 1) The assembly according to claim 1, wherein the fluid comprises a pharmaceutically active compound. ### Claim 13 An assembly comprising: a needle with an inlet, an outlet, and a hollow body that connects the inlet and the outlet, wherein the body has a bend, a needle hub, wherein the needle is fixed to the needle hub, a reservoir containing fluid, the reservoir is in fluid communication with the needle, and a housing, wherein the inlet of the needle defines a first flow direction for the fluid and the outlet of the needle defines a second flow direction for the fluid, wherein the first flow direction is inclined with respect to the second flow direction, and wherein the needle hub is rotatably mounted to the housing such that the needle hub is axially secured but rotatable with respect to the housing, the needle hub being rotatable relative to the housing such that a longitudinal axis of the outlet of the needle points toward a dose member. ### Claim 14 An assembly comprising: a needle with an inlet, an outlet, and a hollow body that connects the inlet and the outlet, wherein the body has a bend, a needle hub, wherein the needle is fixed to the needle hub, a reservoir containing fluid, wherein the reservoir is in fluid communication with the needle, an assembly housing comprising a first housing part and a second housing part, and a needle housing for supporting the needle, wherein the inlet of the needle defines a first flow direction for the fluid and the outlet of the needle defines a second flow direction for the fluid, wherein the first flow direction is inclined with respect to the second flow direction, and wherein the needle hub is rotatably mounted to the first housing part such that the needle hub is axially secured but rotatable with respect to the first housing part, the needle hub being rotatable relative to the assembly housing such that a longitudinal axis of the outlet of the needle points toward a dose member.
