RELEASABLE MONITOR WITH OPTICAL DOSE COUNTER FOR A MEDICAMENT INHALER
First Claim
1. A device for monitoring patient usage of a medicament inhaler, said medicament inhaler being adapted to deliver doses of medicament, and wherein said medicament inhaler includes parts which move during the dispensing of a dose of medicament,wherein said device includes:
- a) a housing, said housing being releasably attachable to said medicament inhaler,b) an optical dose counter associated with said housing, said optical dose counter being adapted to determine when a dose of medicament has been dispensed by transmitting optical signals through the medicament inhaler, said optical dose counter including;
a) at least one light transmitter able to transmit an optical signal, from a position outside of the medicament inhaler,b) at least one light receiver able to receive the optical signal, from a position outside of the medicament inhaler,the arrangement and construction being such that the movement of said part(s) within the medicament inhaler during the delivery of a dose of medicament alters the optical signal(s) whereby the optical dose counter is able to determine that said dose has been dispensed,c) an electronic control module associated with said housing, said electronic control module including, or being in communication with, said optical dose counter,d) said electronic control module being adapted to monitor and/or store data relating to patient usage of said medicament inhaler,the arrangement and construction being such that said device is attachable to said medicament inhaler, and subsequently operable, without any modifications being required to be made to said medicament inhaler.

Abstract
A device for monitoring patient usage of a medicament inhaler, the medicament inhaler being adapted to deliver doses of medicament, and the medicament inhaler including parts which move during the dispensing of a dose of medicament. The device includes a housing, for releasable attachable to the medicament inhaler, and an optical dose counter, associated with said housing, the optical dose counter being adapted to determine when a dose of medicament has been dispensed by transmitting optical signals through the medicament inhaler. The device is attachable to the medicament inhaler, and is subsequently operable, without any modifications being required to be marks to the medicament inhaler. The device may also include an electronic control module which is in communication with the optical dose counter, the electronic control module being adapted to monitor and/or store data relating to patient usage of the medicament inhaler.

1. A device for monitoring patient usage of a medicament inhaler, said medicament inhaler being adapted to deliver doses of medicament, and wherein said medicament inhaler includes parts which move during the dispensing of a dose of medicament,
wherein said device includes: -
a) a housing, said housing being releasably attachable to said medicament inhaler, b) an optical dose counter associated with said housing, said optical dose counter being adapted to determine when a dose of medicament has been dispensed by transmitting optical signals through the medicament inhaler, said optical dose counter including; a) at least one light transmitter able to transmit an optical signal, from a position outside of the medicament inhaler, b) at least one light receiver able to receive the optical signal, from a position outside of the medicament inhaler, the arrangement and construction being such that the movement of said part(s) within the medicament inhaler during the delivery of a dose of medicament alters the optical signal(s) whereby the optical dose counter is able to determine that said dose has been dispensed, c) an electronic control module associated with said housing, said electronic control module including, or being in communication with, said optical dose counter, d) said electronic control module being adapted to monitor and/or store data relating to patient usage of said medicament inhaler, the arrangement and construction being such that said device is attachable to said medicament inhaler, and subsequently operable, without any modifications being required to be made to said medicament inhaler. - View Dependent Claims (2, 3, 4, 5, 7, 8, 9, 10, 12, 13, 18, 20, 21, 22, 23, 26, 27)
the arrangement and construction being such that the movement of said part(s) within the medicament inhaler during the delivery of a dose of medicament alters the optical signal(s) whereby the optical dose counter is able to determine that said dose has been dispensed.
