Device with time indicating means
First Claim
1. A timer device, comprising:
- mechanism (35) operatable between a first condition and a second condition, timer (31),(32) for storing a first time stamp, a second time stamp, and a first time-period value, a controller for setting a first time stamp in response to the contact means being operated between the first condition and the second condition, setting a second time stamp in response to the contact means being operated between the second condition and the first condition, calculating the time elapsed between the first and second time stamps, comparing the elapsed time with the first time-period value, and performing a first control action if the elapsed time is greater than the first time-period value.

Abstract
The invention relates to a timer device capable of performing one or more control actions in response to the time lapsed since a user initiated action took place. The timer device comprises contact means operatable between two conditions, timer means, and means for storing first and second time stamps. The device further comprises control means for setting a first time stamp in response to the contact means being operated between first and second conditions, setting a second time stamp in response to the contact means being operated between the second and first conditions, calculating the time elapsed between the two time stamps, comparing the elapsed time with a preset time value, and performing a control action if the elapsed time is greater than the preset time value.

6. A method for operating a medical device, comprising the steps of:
-
setting a first time stamp in response to a mechanism sensing an operation between a first and second condition, setting a second time stamp in response to a mechanism sensing an operationg between the second condition and the first condition, calculating the time elapsed between the first and second time stamps, comparing the elapsed time with a first time-period value, and performing a first control action if the elapsed time is greater than the first time-period value.

7. A cap (20) having an open end and an interior space adapted to receive a medical device, the medical device comprising means for administering a preset dose of a drug to the patient, the cap comprising a timer device having a contact means or alternatively a switch mechanis, wherein the contact means or switch mechanism is adapted to be operated between the first condition and the second condition when the cap and the medical device are removed from each other, and the contact means or switch mechanism can be operated between the second condition and the first condition when the medical device are received in the cap interior.
