Abstract
Abstract A medical timer apparatus being suitable for use with both integral and non-integral medication containers, and having a magnetically responsive switch for resetting the time measurement function. The magnetically responsive switch responds to magnets positioned such that the magnets will be brought into operable range of the magnetically responsive switch by activities that are consistent with administration of the medicine.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
191 words
In medical timer apparatus having means for measuring time, an improvement comprising: (a) providing said apparatus with a magnetically responsive switch for restarting the measurement of time; (b) providing said apparatus with an integral medication container that may be selectively opened and closed with respect to said apparatus to make accessible and non-accessible, respectively, medication located within said integral container and further including within said integral container a first magnet, such that opening said integral container will position said magnet to activate said magnetically, responsive switch, and wherein said integral medication container may be non-permanently attached and removed, selectively, to and from said apparatus, and further including: (c) providing said apparatus with non-integral container attachment means for use with a non-integral medication container, comprising: (i) a second magnet attached proximal to the non-integral medication container; (ii) sponge means for disposition between said magnetically responsive switch, and the non-integral medication container; and (iii) fastening means for maintaining said apparatus in operable attachment with said non-integral medication container, such that upon squeezing said combined non-integral medication container, attachment means and apparatus, the magnet of said attachment means will activate said magnetically responsive switch.
Claim 2
Dependent Claim
191 words
In medical timer apparatus having means for measuring time, an improvement comprising: (a) providing said apparatus with a magnetically responsive switch for restarting the measurement of time; (b) providing said apparatus with an integral medication container that may be selectively opened and closed with respect to said apparatus to make accessible and non-accessible, respectively, medication located within said integral container and further including within said integral container a first magnet, such that opening said integral container will position said magnet to activate said magnetically, responsive switch, and wherein said integral medication container may be non-permanently attached and removed, selectively, to and from said apparatus, and further including: (c) providing said apparatus with non-integral container attachment means for use with a non-integral medication container, comprising: (i) a second magnet attached proximal to the non-integral medication container; (ii) sponge means for disposition between said magnetically responsive switch, and the non-integral medication container; and (iii) fastening means for maintaining said apparatus in operable attachment with said non-integral medication container, such that upon squeezing said combined non-integral medication container, attachment means and apparatus, the magnet of said attachment means will activate said magnetically responsive switch.
Claim 3
Dependent Claim
37 words
The improvement of claim 1 wherein said second magnet comprises a substantially flexible magnetic material having adhesive disposed on at least one side thereof such that said second magnet may be affixed to the non-integral medication container.
Claim 4
Dependent Claim
32 words
The improvement of claim 1 wherein said medical timer apparatus includes alarm means for setting and activating an alarm, and said magnetically responsive switch operates also to terminate activation of said alarm.
