Nebulizer
A nebulizer having an insertable container and a monitoring device for counting actuations of the nebulizer is proposed. The monitoring device is mounted in a detachable housing part and directly detects movements of container during a nebulizing process, an air supply current in the region of a mouthpiece, and/or the production of aerosol, in order to detect this as the actual dispensing of fluid and actuation of the nebulizer, while preferably the time of actuation of the nebulizer is additionally detected and stored. This allows better monitoring and guidance for the user.
1. A hand-holdable nebulizer for a fluid comprising: a container containing the fluid, a manually operated, pressure generator for conveying and/or nebulizing the fluid, and a monitoring device for counting actuations of the nebulizer,
wherein the monitoring device comprises a timer and a memory so that the number and times of the actuations can be detected and stored, wherein the timer measures only relative time, and
wherein at least one of:
a) the absolute start of the relative time measurement is indicated by on initiating or first switching on of the monitoring device and is stored in one the memory or another device; and
b) the absolute end of the relative time measurement is determined by interrogating the monitoring device and by comparison with an absolute time base
wherein the monitoring device is operative for detecting the absolute times of the actuations of the nebulizer and for storing the detected absolute times in the memory.
2. A nebulizer for a fluid comprising:
a container containing the fluid, a pressure generator for at least one conveying and nebulizing the fluid, and a monitoring device for counting actuations of the nebulizer, wherein the monitoring device is mounted on a detachable outer housing part of the nebulizer, and allows the monitoring device together with the outer housing part, to be removed from the nebulizer and from the pressure generator, the outer housing part being detachable for one of inserting and replacing of the container.
3. A nebulizer for a fluid comprising:
an insertable or exchangeable container containing the fluid, a pressure generator for at least one of conveying and nebulizing of the fluid, and a monitoring device for counting actuations of the nebulizer, and and
a connecting device on a housing of the nebulizer that comprises an interface for communication, via the interface, with the monitoring device, said connecting device being connectable for externally transmitting data from the monitoring device.
4. A nebulizer for a fluid comprising:
an insertable or exchangeable container containing the fluid, a mechanically driven pressure generator for at least one of conveying and nebulizing of the fluid, and a monitoring device for counting actuations of the nebulizer, and
wherein at least one of the nebulizer and the monitoring device has means for interrogating identification or coding on the container and for enabling actuation of the nebulizer only when at least one of the container and fluid are identified by the interrogation as being the correct one to be used.
5. A nebulizer for a fluid comprising:
a mouthpiece, an insertable or exchangeable container containing the fluid, a pressure generator for at least one of conveying and nebulizing of the fluid, and a monitoring device for counting actuations of the nebulizer,
wherein the monitoring device is adapted so that actual dispensing of fluid can be detected and counted electronically as an actuation of the nebulizer, and
wherein an optical spray sensor is provided which optically detects whether droplets of the nebulized fluid or aerosol have actually formed in the region of the mouthpiece.
