Description

" ~2~0~67 The present invention relates to a portable appa-ratus for acquiring and processing data relative to the dietetics or the health of a person.
The invention relates more particularly, but not exclusively, to persons subjec~ed to supervision of their food diet or persons subjected to a medical treat-ment/ such as diabetics.
The aim of the invention is especially to provide apparatus which allows the persons concerned to follow the dietetic and/or medical prescriptions more easily, to take into account repetitive data and to be able to communicate this latter to the doctor in attendance or to a supervising body.
From the US patent N 4.321.574 a device i5 known capable of cumulaking and displaying the number of calo-ries corresponding to the food and/or the drink taken by the user. This known device comprises:
- a certain number of data introducing keys, some corresponding to the main types of food and/or drinks, and the others providing validation or cancelling of data introduction;
- means for displaying the carbon~hydratè, protein, fat and calorie contents of the food and/or of the drinks considered, and at the same ~Lme the typical daily proportions of these constituents in foods and drinks;
- keys for introducing these typical daily pro-portions;
- food/drink switching means; and - appropriate storage and computer means.
Moreover, the user ~as a table of~the different types of food informing him which k;eys he should actuate and how many ~imes, depending on the nature and tbe amount of the food or drink.
~ Thi;s is a simplified device only gi~ing approximate ~: : : : :: : :

:

~2~ 7 ~alues of thP ea~bohydrates , p~otein and fat and caiorie contents of meals, the number of the types of f~od and/Dr drinks being greatly reduced; with this device~ the ùsPr must refer to a table with the composition of foods, whereby there 5 is a risk of errors in determining the key t~ be actuated and the number ~f times it must be actuated so as to take the amounts into account.
Furthermore, it doe~ not allow the times when meals are taken to be taken into account, nor the nature and 10 amounts of the different foods and drinks consumed by the user to be stored, nor finally the data to be transfer~ed to anDther unit, such as a computer 9 for checking ~nd super~ision by a dDctor or an organisation.
~he U5 patent N 4.281.3~0 deseribes a device For 15 supervising ~nd recording medical treatments with keys for the different treatments, different medicaments ~nd the amounts of medicaments. A clock is provided. ~he treatments, medicaments, amounts and times are processed in a microprocessDr D~ the device, then transmitted for recDrd-20 ~ng to a thermal printer and a magnetic tape recorder, thislatter also receiving the indications frum sn electr~-cardi~graph~
It will be noted thst in these two ~no~n devices:
- the keys ~re permanently presssisned t~ one type of 25 fDDd or drink, in one, or to a treatment, medicament, an amountl in the other, without pDssibility of development or mDdification, the fir~t device being purely dietetic and the aecnd purely medical;
- n~ provisicn is made fnr s~oring the input data, but 30 only of the results elaborated ~ro~ these inputs;~
;the direct transfer of the~whole~of the data intrD-duced~with the dats Df this introduction cannot be transfer-red to~anDther unit, such~ as a~cDmputer, likely to be used by a doc~or or~a super~vising organ~isation for super~
35~uising the ~diete~ics~end/or the health~of th~ use~r and ~tD
establish prescriptinns for this latter.
~- ~he object of the present invention is ts palliate : ~

the above mentioned drawbacks by pro~iding a portable self contained and personnalisable apparatus for introducing a large number of very precise data concerning the nourish-ment and/or the medical treatment oF a person, for memori- -5 zing this data with the time at which they are introdlJced and transferring this data with their time of introduction to another unit.
To tllis end, tbe portable apparatus ~or ac4Jiring and processinr] data relative to the dietetics and/or the l~ealth lO of a person, accordirlrJ to the inverltion, is characterized by the fact that it comprises, in combination, a series of alpllarlumeric keys inputting information relative to the dietetics and/or the healtil of t!le user; at least one read only memory (ROM) in which data and instructions in relation 15 \uith this information are storecl; means for displaying the inforlnation introrluced and indications concernin(~ tllem camirl~ Froln the R~JM; rneans For e~fectively inputtlrlg and refusing the inputtin(J of this information; cloek mealls for dating eacll information input; at least one randon access 20 memory (RAM) adapted to store the inputted information as well as its date; computing means adapted ~to determine~, frorn the inputted information and from data stored in the ROM, instructions intended for the user af the~ap;paratus and relati~e to the dietetics`and/or the health of the user;
25 main electric power supply means of the~apparatus; and communication means for allowing inforrrlation stored in~the~
RAM to be transferrect to an external clata processing unit as well as in return the introduction, into this RAM, of instructions coming~from said unit.

For example, in the case of a food diet, the glossary will give the correspondance between eacll food concerned and th-e cipllers of the code When the apparatus is intended for persons bound to a food diet, for example diabetics, the ROM contains data relative to a certain number of foods, this data being form-ed more especially by the average proteid, lipid, glucici, alcohol and calorie content oF the food in question, and the computing means are adapted so as to detèrmine, for each food, depending on the amount which will be absorbed, the amount of proteids, lipids, tJlucids, alcohol and calories.
The qualitatiue and quantitative detail of the meal is stored, with its data, in the RAM. This RAM may further contain personalized information which is entered, for example, during a medical consultation and which relates to the da;ly referencc amounts of proteids, lipids, rJlucids, aLcohol and calories wllich may be consumed by tho persoll concerned and the computing means will cause to be displayed before each information input relative to a meal or to Food~

The ~OM 4 contains the nlonitor program controlling the general functions of the calculator: management of the l<eyboard, management of the display, possibly continuous display of the time, supervision of the room available in the 5 ROM ~, management of the peripherals etc.
The ROM 4 further comprises programs corresponding to three specialized keys 3a (meals), 3b (glycernia~ and 3c ~treatment).
1. Should the "meal" key 3a be actuated, the calculator lO will operate in accordance with the "dietetic" program of the ROM 4. When the ciphered or mnemonic code of a food is entered with the keyboard, the name of this food (for example semi-skimmed milk, as shown in Figure 1), possibly abbreviated, appears displayed in clear language Otl screen 15 5. The pro9ram of the ROM 4 then requests the amount absorbed, ln a current unit of measuremerlt which may, For oxample in a very practical way, be a SOUp or coffee 9~0011 or a qlass as inclicated for example in Figure 1~ Each food absorbed, referenced by an internal 8 bit code (possib-20 ility of cataloguing 256 foods) is stored (in the RA~il 8, inthis form with the amount and date).
Thus, at the time of the meal, the person concerned records the composition of the meal and obtains the total proteid, lipid, l~lucid, alcohol and calorie amount thereof 25 which appears on screen 5. Severa} tests of the composition oF meals may b~ effected, before validating, by pressing I<ey 3e, the composition of a meal and before consuming this meal .
Cumulated over 24 hours9 these results allow the daily 30 food rations to he balanced. After each meal, the remaining proteid, llpid, glucid, alcohol and calorie credit is automatically determined by the calculator by deducting from tlle preceding credit the composition of the meal which has just been stcred in me~rnory. When the "meal" ~ey 3a is 35 actuated, the present proteid, lipid9 glucid and calorie credit appears on screen~5.
Every day, that~is to say every 2~4 hours, at a definite : :

~21~367 time given by the internal clock 6, for example at midnight, the daily food credit is reset to its initial value, which value will have been prescribed by the doctor or a super-vising organisati.on, for example during a consultation Dr . 5 a preceding meeting, and introduced i.nto the RAM 8 through the connector ll.
The automatic cornputation, by apparatus l, of the proteids, lipids, glucids, alcohol and calories oF a meal is effected by means of the table stored in the R0t`1 4, in l0 whicll each food or drink comprises its average and approx-imate proteid, lipid, glucid and alcohol.composi.tion. The calorie calculation is made from this data.
The balance for each food may be obtained displayed on screen 5 and a coding error may be cancelled out at any 15 tirne.
The summation is effectecl for the whole of the meal, and the difference in excess or in deficit with respect to the theorctic diet, as explained abova, remains 1<nown until the next meal. The complete composition of the.meal, 20 associated with the schedules supplied by clock 6 is stored in the RAM 8. ~
It should be noted, in so far as supervision of nourishmant is concerned,:that there exists cer~taln private or public extra-medical assoc;iations or;organisat:iorls which 25 attempt to help~people having nutrition troubles, obesity, etc.

This information may be stored in the RAM of the calculator; and, during a periodic meeting, a systematic analysis for each participant may be drawn up by the 5 association's computer3 by means of connector 11 of the calculator.
Since this information is stored with a date and time of its introduction by means of the keyboard, the "dietetic - chronology'l may even be reconstructed, since a large number: ' :

and the dose of medicament absorbed or insulin injected.
This information is stored in the RAM 8 as well as the time and the date at which this treatment was carried out.
Generally, the accessory functlons,such as the rerninder of 5 the date of the next consultation, the interrnittant display of particular information, may be provided by a specific program using the RAM 8.
All the information introduced (composition oF the meal, glycemic ualue, type and dose of treatment), associated 10 with the corresponding timetables are thereFore stored in the ~AM 8 of the calculator. The whole is designed so as to automatically suspend operation, without loss of info~mation, if the storage capacity of memory 8 is exceeded. -At the time of the next consultation, by connecting to 15 connector 11, through an appropriate interface, all the information stored in the RAM 8 i3 transFerred to the computer of the doctor who may then have the data processed instantaneously or postpone the processing.
Given a rnonthly rate of consultation, a storage possi-20 bility for a minimum of 45 days is provided~ so as to takeinto account possible postponements of appoin~tments.
At each medical consultation, the informat.ion stored in the RAM 8J relative to foods, to glycemia and to the taking ;
of medicaments, ar~ erased after being transferred into the 25 doctor's computer, so that the RAM 8 is ready for new recordings.
It should be noted that the apparatus 1 is "perso`nnallzed"
at the very time of its first use, during the first consultation. This personnalisation consists in introducing :
into the RAM 8 information relative~ to the person~concerned, in particulars name of this person9~characteristics of the food~diet, of the medlcaments~ and~treatments prescr~ibe~d, dste~of the present c~ns~ultation~and~oF th~next~ o~sultat~on, ~This information may~-be updated~by the doctor during ~ ~subs~equent consul~t~ations.;~

The time base 6 may be adapted so that its output allows the dates to be memorized, quarter of an hour by quarter of an hour, from a "zero" date input into the storage memory from the computer of the doctor, this "zero" date being 5 recorded at each appointment. For a period of 45 days, the quarter of an hour time intervals represent then about 4500 periods which may be stored. At each consultation, the exact date i9 corrected at the same time as the start of the time counting is initiated.
The display screen 5 comprises, in addition to a signalliny reference system, at least one line of 30 alpha-numeric characters for writing in clear language the foods and the amount absorbed, and more generally any information inputted by the keyboard and any instruction given by the 15 apparatus, Preferably, the ROM 4 and the RAM 8 each have a capacity of I K Bytes.
Apparatus 1 is equipped with a double power supply system by means of rechargeable batteries E, thus providing 20 independent operation. Apparatus 1 may, if required, be provided so as to operate also from the mains F. Advanta-geously a possibility is provided for testing the state of charge of the batteries an~d for controlling the general power supply at 13 and the power supply of the microprocessor 25 I4.
The RAM 8 remains supplied, from a second ~attery G
(safeguard power supply?, even if the calculator is not used, and even when the main battery E is discharged.~
For determining the quantity of glucose in the blood, 30 an automatic apparatus~wit~h diglta~l dlsplay`may be used ;~
such a~s are commercially~av~ailable, for example the~ one known~under~the~name~"AMES glucorneter".~

Control of switching on and of sharing the buses by the interface is advantageously provided as follows.
A first electronic circuit, supplied permanently with power by the battery E of the apparatus, receives control 5 information:
- from the keyboard C itself permanently supplied with power - from the microprocessor 9 - from the interface connector 11.
A In portable use, actuation of keyboard C activates this circuitl which then drains the current towards the assembly of components , except the microprocessor 9. Among these cornponents, a second control circuit is fed with current from this time on. This second circuit receives addit:ional 15 control information from the intarface collector ll~ depend-ing on which it conducts the currents towards the rnicro-processor ~ or not.
First case: the in~Formation is absent; then the second circuit is conducting and microprocessor 9 starts to 20 operate; the internal program proceeds and then controls a signal which returns to activ~ate permansn~t1y the first circuit, so that this latter remains conducting: it is ~`
"self-feed": then the keyboard C may~be released,~and the~
microprocessor continues its activity`until the time when 25 ~t cuts off its self supply s;ignal. ~
Second case: the information is present~; ~in this case the sacond circuit remains non conducting and microprocessor 9 does not start operating; the whole of the power supply is cut off as soon as keyboard ~ is released.
B.~ In usé via the connector 1~1, the~interface may play the role of the keyboard;by~acti~ating~the first~ircuit~
If it does not~give the infcrmation describzd~above, micro-~pr~oces~sor 9 is~activat~ed;~;(see f~lr;st case above).

through the connector ll, since it has availa~e the con-trol H~ the data bus D and the address :bus A, is consequently able to use all ~e resources of the calculator, ~ithout interference with the signals of the microprocessor 9 there~
of which it inhibits.
It is clear that the calculator l of the invention may be used and adapted to oth8r types of information relative to the nutrition and/or health of a person. For example, such an apparatu-s could be adapted to information relative to the blood pressure, and to the rate of heart ~eat.
