An aerosol assembly for a medicament delivery device, the aerosol assembly comprising:
- a nozzle chip assembly including a carrier and a nozzle chip provided on the carrier,
- a holding structure having a fluid channel extending through the holding structure,
- wherein the nozzle chip assembly is configured to be mounted into the fluid channel such that fluid flowing through the fluid channel passes through the nozzle chip,
- an elastic sealing member configured to be arranged with a tight fit in the fluid channel, the sealing member having a central through-opening configured to receive the nozzle chip to seal the nozzle chip towards the carrier, and
- a base member having a Luer cone configured to extend into the fluid channel towards the nozzle chip assembly, the Luer cone having a central channel extending through the base member and configured to extend coaxially with the fluid channel, wherein the base member and the holding structure have Luer threads by which the base member and the holding structure are configured to be connected, wherein the central through-opening of the sealing member is configured to open towards the central channel, wherein the sealing member is configured to be arranged axially between the Luer cone and the carrier, and wherein the sealing member is configured to be in contact with the Luer cone and with the carrier.
An aerosol assembly for an inhaler, where the aerosol assembly comprises:
- a nozzle chip assembly including a carrier and a nozzle chip provided on the carrier;
- a holding structure having a fluid channel extending through the holding structure, where the nozzle chip assembly is configured to be mounted into the fluid channel such that fluid flowing through the fluid channel passes through the nozzle chip;
- an elastic and rotationally symmetric sealing member is arranged with a tight fit in the fluid channel, where the sealing member has a central through-opening configured to receive the nozzle chip;
- and
- a base member having a Luer cone configured to extend into the fluid channel towards the nozzle chip assembly, the Luer cone having a central channel extending through the base member and configured to extend coaxially with the fluid channel, wherein the base member and the holding structure have Luer threads by which the base member and the holding structure are configured to be connected, wherein the central through-opening of the sealing member is configured to open towards the central channel, wherein the sealing member is configured to be arranged axially between the Luer cone and the carrier, and wherein the sealing member is configured to be in contact with the Luer cone and with the carrier.
