Apparatus for infusing medication
First Claim
1. An apparatus for infusing liquid medication, comprising:
- time base means for generating time information;
memory means for storing first infusion information indicative of a liquid medication infusion dose which varies with time information generated by said time base means, and second infusion information corresponding to a meal pattern determined by the time information generated by said time base means;
first addressing means for effecting an address designation in accordance with said time information upon establishing correspondence between a portion of address information for reading out information stored in said memory means, and said time information;
second addressing means for designating respective addresses in accordance with which of the first and second infusion information is selected, a first specific address being designated when said first infusion information is selected, a second specific address being designated when said second infusion information is selected, said second specific address being updated in accordance with time until the designated address returns to said first specific address of said first infusion information; and
infusion means driven in accordance with infusion information read out of said memory means for infusing said liquid medication into a living body.

Abstract
An apparatus for infusing liquid medication such as insulin into a living body has a memory for storing a basic pattern and meal patterns which decide the medication infusion dose in accordance with time. The basic pattern is designated under ordinary conditions, with a meal pattern being designated for a predetermined period of time when desired. With the passage of the predetermined period, the basic pattern is restored, the address of the basic pattern being designated according to the actual time. When a pattern is selected, the one actually addressed and read out of the memory is that appropriate for the time of day. The pattern information read out of the memory is applied to means for infusing the liquid medication into the living body, the dose of the medication conforming to the specific pattern.

13. An apparatus for infusing liquid medication, comprising:
-
time base means for generating time information; readable/writable memory means for storing first infusion information indicative of a liquid medication infusion dose which varies with time information generated by said time base means, and second infusion information corresponding to a meal pattern determined by the time information generated by said time base means; first addressing means for effecting an address designation in accordance with said time information upon establishing correspondence between an address of said memory means and said time information; first selection means coupled to the output side of said first addressing means for selectively receiving address designating signals from said first addressing means and externally applied address designating signals; second addressing means for designating an address in accordance with which of the first and second infusion information is selected, a first specific address being designated when said first infusion information is selected, a second specific address being designated when said second infusion information is selected, said second specific address being updated in accordance wih time until the designated address returns to said first specific address of said first infusion information; second selection means coupled to the output side of said second addressing means for selectively receiving address designating signals from said second addressing means and externally applied address designating signals; data input means for receiving externally written data; means for controlling the writing and reading of data to and from said memory means; write signal input means for applying a write control signal to said write/read control means when data is externally written; means for generating an internal clock applied to said write/read control means; high-impedance setting means connected to the output side of said internal clock generating means for selectively receiving said internal clock and an externally applied clock; and infusion means driven in accordance with infusion information read out of said memory means for infusing said liquid medication into a living body. - View Dependent Claims (14)
