fig1 shows the recording equipment 1 which can be worn on the patient &# 39 ; s body and which is approximately the size of a wristwatch or pocket calculator . this equipment has , on its front side as shown in the drawing , three buttons 2 , 3 and 4 which are provided with the capital letters m , n and p . a display 5 is also provided which indicates the time since medication was taken and / or the clock time which can be selected via a button 7 . finally , a removable chip 8 is shown which , as recording medium , contains the recorded values . the equipment is operated as follows . the patient who is wearing the equipment on his body , or is carrying it with him , first takes the medication prescribed by the doctor and at the same time pushes the button m . this starts up a stopwatch , i . e . the time begins to run at zero and is optionally shown on the display 5 . if , after taking the medication , the patient now experiences a positive effect , he presses the p button 3 . the equipment acknowledges that the button has been pressed by emitting an acoustic signal ( beep ) or an optical signal from a light 6 , so that the patient receives confirmation of the entry he has made . if , after some time , the patient feels the effect is diminishing , he presses the n button 4 . he then takes his medication for the second time as instructed by his doctor , and once again presses the m button 2 , as a result of which the time is stored . the procedure described above is then repeated , i . e . pressing the p button when he experiences a positive effect and pressing the n button when he feels the effect diminishing . this is of course done in each case on the basis of the patient &# 39 ; s subjective feelings . the result of a single cycle of entries of this kind made by the patient is shown in the diagram according to fig2 . there , the positive effect of the medication is plotted on the ordinate over the time axis t , and only as a positive value of the order 1 . the start of the measurement cycle upon administration of the medication is marked by the point m 1 on the abscissa , i . e . the time axis . here , therefore , the effect of the medication is equal to 0 . after some time , the so - called latency period l , the patient first experiences a positive effect and he presses the p button , as a result of which the value f ( 1 )= 1 is recorded at the time t 1 . after a further time span , at the time t 2 , the patient feels the effect diminishing or completely disappearing and he presses the n button , as a result of which the value f ( 2 )= 0 is recorded . the next time on the time axis is m 2 , i . e . the time t 3 , at which the medication is taken a second time . m 2 is recorded by pressing the m button ; as can be seen , the effect of the medication is still zero at this time t 3 , so that a so - called void time f occurs , i . e . a time span t = t 3 - t 2 in which there is no effect of the medication . after the second administration of medication m 2 , there is once again a latency period l &# 39 ;, i . e . the time difference to the time t 4 , at which the patient once again experiences a positive effect and presses the p button 3 . this second latency period l &# 39 ; can be different than the first period l . the measurement cycle begun in this way can be continued as often as desired by repeated administration of the medication at the subsequent times m 3 , m 4 , . . . m i , with corresponding recording of the effect . the result is stored as a function according to the pattern in fig2 and can be removed as a recording medium , e . g . on the chip . it would also be possible to analyze the stored function directly on a pc via a pc adapter , e . g . by comparing the effect profiles on different days , or to print out the stored function . this data , i . e . the effect function , helps the doctor to adopt a corrected or optimum medication program for the patient , and this with the goal of eliminating the abovementioned void times f and subsequent repeated latency periods l &# 39 ;, i . e . the time spans in which there is no effect of the medication . fig3 shows a further illustrative embodiment of the invention , namely the recording equipment 10 in the form of a wristwatch with securing brackets 11 and 12 for a strap ( not shown ). the equipment 10 , which is thus of essentially circular design in its plan view , has in the first place the m button 13 and the other buttons 14 and 15 for inputting a positive and a negative effect , the button 14 showing a laughing face and the button 15 showing a sad face . moreover , a display 16 is provided for optionally displaying a running ( stopwatch ) time and the clock time , it being possible for the appropriate mode to be selected using the button 17 . the equipment 10 also has five optical devices 19 ( light - emitting diodes ) which represent a respective recorded value . five optical devices 21 ( light - emitting diodes ) are correspondingly provided on the left side of the circular equipment 10 for displaying the recorded negative effect . between these two groups of five 19 and 21 , a light arrangement 18 is provided for the zero setting , i . e . no effect . the equipment 10 also has a larger light arrangement 20 which is intended to signal an optimum for the patient &# 39 ; s state of health . finally , three further light arrangements 22 are provided for a so - called excess effect of the medication . the aforementioned groups of light arrangements are of different geometric designs and light up in different colors , e . g . group 19 and 20 in green , group 21 in blue and group 22 in yellow . finally , an acoustic or optical signal arrangement 23 is provided in the area of the &# 34 ; clock face &# 34 ; of the equipment 10 , which arrangement 23 emits acoustic or optical signals at the preprogrammed time for taking medication ( m 1 , m 2 , m 3 , etc .) in order to remind the patient to take the medication . the signal can also be generated by vibration . finally , the equipment has a connection point 24 for an adapter ( not shown ) via which the stored data can be transferred to a pc and can be displayed on its screen . the function recorded and stored using the equipment 10 according to fig3 is shown in the diagram in fig4 . both the positive effect and the negative effect after taking medication are plotted over the time axis t , with five values p1 to p5 being provided for the positive effect and five values n1 to n5 for the negative effect . above the value p5 there is a value opt , representing the optimum , i . e . the best the patient feels , and above this there are three further values for an excess effect of the medication u1 , u2 , and u3 . the diagram shown represents the variation in effect between the times at which medication was taken m1 and m2 and is recorded by pressing the buttons 13 ( m ), 14 for a positive effect and 15 for a negative effect . the measurement cycle begins at the time t 0 at which the patient presses the button m or 13 on first taking the medication . after the latency period l has elapsed , he experiences a first positive effect and presses the button 14 once at the time t 1 , as a result of which the value f ( 1 ), corresponding to the value p1 , is recorded on the positive ordinate . at the time t 2 the patient experiences an increasing positive effect which he assesses subjectively with the value p4 , and for this he has to press the button 14 three times in succession , which results in a jump from p1 to p4 to the value f ( 2 ). when the value p1 is recorded , the first light arrangement 19 lights up ( green ), and when the value p4 is recorded three further light arrangements 19 light up , that is to say altogether four light arrangements 19 are lit . at the time t 3 the patient experiences an optimum effect and presses the button 14 again , as a result of which he reaches the value p5 , and by pressing the button 14 one more time the value opt , i . e . the optimum , corresponding to f ( 3 ) is reached , and at the same time a larger light arrangement 20 lights up ( green ). the patient thus sees that the optimum effect of the medication has now been recorded . at the time t 4 he experiences an excess effect of the medication and therefore presses the button 14 once again , as a result of which the value f ( 4 ), corresponding to u1 , is recorded on the ordinate . when the value u1 is reached , i . e . recording of an excess effect , the further light arrangement 22 lights up ( yellow ), thus optically signalling the range of the excess effect . if the patient feels this excess effect diminishing , he can press the button 15 , as a result of which , if the latter is pressed once , the value opt ( optimum ) is once again reached . if the effect further diminishes , the patient can once again press the button 15 -- one unit is subtracted for each single actuation . in the case shown , by pressing the button 15 four times , he reaches the value p3 at the time t 5 , corresponding to f ( 5 ), and by pressing it again he reaches the value p2 at the time t 6 , corresponding to f ( 6 ). at the time t7 the patient experiences a greatly diminishing effect , dropping into the negative range . he therefore presses the button 15 four times and reaches the negative value f ( 7 ) corresponding to n2 . at the same time , two light arrangements 21 now light up ( blue ); five light - emitting diodes 21 ( blue ) are provided corresponding to the negative scale of values n1 to n5 . the next time t 8 corresponds to the planned time m2 for taking the second dose of the medication . in this case , therefore , there is still a negative effect of the medication which lasts until the time t 9 : only then does the patient experience a positive effect again , and he presses the button 14 with the laughing face three times and reaches the value f ( 9 ) which corresponds to the value p1 on the ordinate . the time span between t 8 and t 7 corresponds to the void time f in which there is no positive effect of the medication , and the time span between t 9 and t 8 is the second latency period l &# 39 ; after taking the second dose of medication . thereafter , the measurement cycle is continued as described above . the groups of light - emitting diodes 19 to 22 can each have different colors ( as indicated above ) or can light up in the same color but with different brightness or with a different contour ( if the patient is color - blind ). this diagram , which can be stored on a recording medium or can be transferred to a pc via an adapter , is used by the doctor as a basis for more accurately adapting the medication , i . e . on the one hand in terms of the choice of times m1 , m2 , m3 etc ., and also in terms of the dose of the medication . the latter can be adapted , for example , if an excess effect occurs -- in this case up to the value u1 over the time t u -- since in this case the dose of the medication was too strong . fig5 finally shows a further design of the invention , namely in the form of equipment 30 which has an enlarged display or a small screen 31 , a keyboard 33 , 34 and the already described buttons with capital letters m , p and n corresponding to reference numbers 35 , 36 , 37 . in addition , a time switch 32 with the capital letter t is provided which makes it possible to switch alternately between stopwatch and clock time . the buttons 34 with the numbers 1 , 2 , 3 through 0 correspond to side effects , e . g . headache , nausea , fever or tachycardia . thus , by using the keyboard , the patient is able to call up on screen the side effect which occurs after he takes the medication and to record the time at which it occurred . in addition to entering side effects , it is also possible to select on the equipment specific symptoms which are intended to be influenced by the medication , e . g . tremor ( trembling of body parts ), muscle mobility , anxiety or agitation , to assess these and to record the time at which they occurred . in this way , different effect profiles can be stored in parallel . finally , the program of this equipment 30 makes it possible to record the effect of combinations of medication , that is to say several medications taken concurrently . fig6 shows a further embodiment of the equipment according to the invention with expanded mode for superposed recording of additional events and symptoms of the disease and their assessment . the equipment 40 , like equipment 1 and 10 , has three buttons which correspond to the buttons m , n and p or 13 , 14 and 15 , i . e . the button 41 with the letter m is intended for entering the time at which the medication is taken , the button 42 with the laughing face is intended for entering a positive effect or assessment and the button 43 with the sad face is intended for entering a negative effect or assessment . a button 44 with the letter w is also provided by means of which certain events and symptoms of certain diseases can be called up on a two - line display 45 and displayed . for example , various main terms such as tremor , mobility , headache , nausea or anxiety can be called up and displayed in the top line 46 of the display 45 by actuating the button 44 ( w ). a possible assessment of the corresponding event then appears in the bottom line 47 . by actuating the button 42 or 43 , an assessment can then be made in different stages , e . g . for headaches : ______________________________________no headache ( 0 ) very slight headache ( 1 ) mild headache ( 2 ) moderate headache ( 3 ) severe headache ( 4 ) very severe headache ( 5 ) ______________________________________ such an assessment is not made in response to a request , but when the patient feels it necessary . the event and its assessment are thus superposed on the recording of the abovementioned effect of the medication according to fig2 and fig4 . the doctor is thus provided with additional information which allows him to make an accurate assessment of the effect of the medication . for visual confirmation of the individual entries made using the buttons 41 , 42 , 43 and 44 , these are each assigned colored lights 48 , 49 , 50 and 51 which light up when an entry is made , namely in yellow ( 48 ), green ( 49 ), red ( 50 ) and blue ( 51 ). the equipment 40 also has a small speaker 52 via which certain entries receive an audible spoken confirmation , e . g . via the speaker the equipment 40 &# 34 ; says &# 34 ; the following words or phrases : &# 34 ; administration of medication recorded &# 34 ; or &# 34 ; effect of medication now : slight improvement &# 34 ;. a push switch 53 is also arranged on the equipment 40 and is used to switch the speaker 52 on and off . a key switch 55 which can be operated by the patient can be connected to the equipment 40 via a cable 54 and connection socket 56 , and entries can be made using this key switch 55 in addition to the buttons 42 and 43 . this key switch 55 represents , as it were , a remote control for the equipment 40 in some cases : for example , by pressing the key switch 55 , it is possible to record additional and sudden events along with their clock time , without the patient having to take the equipment 40 , which he carries with him , out of his pocket . this is particularly advantageous for patients with parkinson &# 39 ; s disease in the so - called off - phase , because the patient is at that time severely restricted in his movements . also in the case of anxiety attacks or other sudden and critical changes in the state of health , e . g . absences in epileptics , the immediate activation of the key switch 55 permits immediate recording of this event . the key switch 55 , however , can also be used as an alternative to the input buttons 42 and 43 , in other words for entering a positive or negative effect of the medication . for this purpose , a code can be used which is easily understood by the patient : e . g . a short press on the key switch 55 would mean that there was no effect of the medication , and a long press on the key switch 55 would mean that there was a positive effect . this remote entry via the key switch 55 can then be confirmed acoustically via the speaker 52 of the equipment 40 , so that the patient knows what has been recorded . alternatively , confirmation by means of vibration is also possible . finally , the equipment 40 also has an attachment 57 for diverse sensors or measurement equipment via which physically measurable data from the patient are recorded . here , by way of example , a measurement sensor 59 , shown diagrammatically , is connected via a cable 58 and is used to measure the patient &# 39 ; s heart rate . alternatively , or in addition to this , further measurement sensors can be connected , for example for measuring the blood pressure , blood oxygen or blood sugar levels , tremor , muscle tone ( muscular tension ) and skin temperature or skin moisture . these objectively measurable values can be measured and recorded automatically , without the assistance of the patient , and can be stored on the abovementioned recording medium and output . in this respect it is possible , with this combination of equipment 40 , for the subjective state of health after medication and the objectively determined physiological values to be recorded and stored in parallel . this represents a considerable therapeutic aid to the doctor and an improvement to the patient &# 39 ; s medication . the drawing does not show a combination of the above - described equipment with a medication dispenser containing the prescribed medication in a quantity suitable for a defined period . at the preset times m 1 , m 2 , m 3 etc . which are stored in the equipment , the medication dispenser opens and supplies the prescribed dose of medication , i . e . the patient can then remove the medication . at the same time , the above - described signal or alarm arrangement can activate and thus remind the patient to take the medication . the medication to be taken at this time can be displayed , e . g . : as has already been mentioned above , the equipment according to the invention is not only intended for use where a patient is being treated with medication by a doctor , but can also be used , for example , in pharmaceutical research when new active substances , remedies , drugs or the like are being tested and evaluated for their effect on the human body .
a portable device for recording a patient &# 39 ; s state of health is described which measures and records the subjective state of health of a patient . with this device the patient himself records the variation in the effect of medication with time by pressing buttons on mobile equipment and stores this data on a recording medium . this equipment has buttons by means of which the patient can enter the time at which the medication was taken and the time and value of any positive or negative effect . this variation in the effect with time is recorded and can be output via a chip and thus reproduced .
