Definitions
- the invention relates to a method and a device for displaying the remaining remaining service life of a battery-operated evaluation device for analyzing a medically important component of a body fluid, in particular a blood glucose measuring device.
- test methods are used on a large scale that work with test elements.
- the test elements contain reagents.
- the test element is brought into contact with the sample.
- the reaction of sample and 5 reagent leads to a change in the test element which is characteristic of the analysis and which is evaluated with the aid of a suitable evaluation device.
- the evaluation device is generally suitable for evaluating a very specific type of test element from a specific manufacturer. 0
- the test elements and the evaluation unit form mutually coordinated components and are referred to as an analysis system. Numerous different types of test elements are known, which differ in the measuring principle and the reagents used and in their structure.
- colorimetric analysis systems are particularly widespread. With them, the reaction of the sample with the reagents contained in the test element leads to a color change which can be measured visually or by means of a photometric measuring device.
- electrochemical analysis systems have become very important, in which the reaction of the sample with the reagents of the test element leads to an electrically measurable change (an electrical voltage or an electrical current), which is measured with appropriate measuring electronics.
- Blood collection systems should be easy to operate, have a compact, slim design and allow simple, inexpensive construction. Based on these practical requirements, blood analysis devices have been and are being developed which, as far as possible, meet these sometimes conflicting requirements.
- Blood glucose devices contain at least one battery, in particular button cells for their energy supply.
- the batteries are inserted into the devices during production.
- the batteries are taped with an insulating tape. This largely prevents discharging before the device is started up.
- the adhesive tape must be removed to start up the device.
- the battery compartment must be opened for this.
- the status of the batteries is shown on a display of the device by means of a single symbol or icon.
- the state of the batteries is determined from the difference between a target value of the battery voltage and a current actual value of the battery voltage.
- a symbol indicates to a user of the device that the battery needs to be replaced. There is therefore no exact indication of the remaining service life. Only a near end of battery life is shown. Overall, this battery change indicator known from the prior art is imprecise and not really reliable.
- a disadvantage of the procedure according to the prior art is that, owing to the fact that the power supply to the device is not carried out until the user removes the adhesive tape, it is not possible to activate a system clock of the device during the production of the device. is borrowed. The device is started up after very different periods of time. Many users either do not activate the system clock or do so incorrectly during commissioning, ie they do not set the system clock to the current time. As a result, measurement data in a measurement data memory of the device cannot be assigned to their measurement time. Reliable long-term monitoring is then not possible.
- the reliability of the battery change indicator according to the prior art is low, since the discharge characteristics of the batteries are not known. There is no reliable indication of the remaining service life.
- the described type of representation of the battery status contains too little information, it is too one-dimensional.
- the removal of the adhesive tape or a battery change is associated with inconvenience and effort for the user of the device.
- the battery compartment must be opened, the correct type of battery must be procured and the batteries must be inserted correctly. For this, the device description may have to be studied.
- a reliable indication of the remaining service life, from which a user can reliably see how many measurements can still be carried out with the battery pack present in the evaluation device, can also be highly safety-relevant. For example, diabetics rely on regularly determining their blood glucose content and, if necessary, on correcting them. by administering medication. It is particularly important for these people that they can assess in advance whether the blood glucose meter they are carrying is still available for a sufficient number of measurements, for example on a trip. If the analyzer fails unexpectedly, for example because a battery change indicator available according to the state of the art cannot indicate a due battery change long enough beforehand and a replacement battery is not available at short notice, life-threatening conditions can even arise due to the impossibility of performing a blood glucose measurement. There is therefore a need to indicate a reliable remaining service life so that the user of an evaluation device can prepare for a due battery replacement in good time.
- the invention has for its object to provide a method for displaying the remaining service life of battery-operated evaluation devices and a corresponding evaluation device which is set up to carry out the method, which overcome the disadvantages of the prior art and enable an informative and reliable determination and display of the remaining service life ,
- a method for displaying the remaining remaining useful life of a battery-operated evaluation device for analyzing a medically significant one Part of a body fluid, in particular a blood glucose meter thus comprises the following method steps: Determination of the elapsed battery life that elapsed between a battery voltage supply point in time at which the evaluation device was supplied with a battery voltage by inserting a battery and the current point in time, the Battery life is determined by means of a system clock of the evaluation device, calculating a remaining number of measurements that can still be carried out with the evaluation device with the battery inserted, using the battery life and one or more further parameters of the battery-operated evaluation device and / or its battery, and displaying the remaining life of the evaluation device based on the calculated Remaining number with a remaining service life display of the evaluation device that visualizes the remaining service life or the remaining number.
- a battery-operated evaluation device for analyzing a medically important component of a body fluid, in particular a blood glucose measuring device, is characterized in that it comprises the following means for carrying out a method according to the invention: - a system clock, a time measuring means for determining an elapsed battery life between a battery voltage supply time, at which the evaluation device was supplied with a battery voltage by inserting a battery, and the current point in time, the time measuring means determining the battery life by means of the system clock, calculation means for calculating a remaining number of batteries with the evaluation device with the battery inserted Measurements that can still be carried out by means of the battery service life and one or more further parameters of the battery-operated evaluation device and / or its battery and a remaining service life display for displaying the remaining service life of the evaluation device based on the calculated remaining number with a remaining service life visualizing the remaining service life or the remaining number. Display of the evaluation device.
- the number of measurements already taken with the battery inserted into the evaluation device since the time of the battery voltage supply be taken into account as a parameter in the calculation of the remaining number. As a result, the quality of the prediction of the remaining useful life can be increased.
- the parameters of the battery can be, for example, one or more of the following act on the general parameters characteristic of the inserted battery type: manufacturer, battery type, maximum electrical charge stored in the battery, voltage-charge characteristic, discharge characteristic, self-discharge over time, temperature dependence.
- the following specific parameters of the battery can also be taken into account: current terminal voltage, total value of the charge or current withdrawn, temperature, history (ie data stored in the evaluation device relating to the parameters mentioned), quiescent current.
- the battery voltage supply time is preferably the insertion of the battery during the production of the evaluation device, the system clock being activated from the battery voltage supply time.
- Evaluation devices especially blood glucose meters, which are already provided with batteries during production, i.e. which are supplied with battery voltage already from production, and whose batteries are optimally selected for a predetermined number of measurements and a suitable runtime, enable the system clock, i.e. a built-in clock, to be activated and set correctly during production.
- the system clock then has the correct time setting.
- a reliable value for the remaining service life of the blood glucose meter is calculated from the time that has elapsed since production, the number of measurements already carried out with the blood glucose meter and parameters of the batteries currently used in the device, and a suitable display for the Provided users of the device.
- the remaining useful life is preferably displayed by means of a number of segments which represent an initial measurement number, the remaining number being displayed in such a way that a number of segments proportional to the remaining number is displayed in a different display mode than that of the other segments representing the initial measurement number.
- the number of segments proportional to the remaining number is preferably represented by the fact that the number of segments
- Number of outgoing segments are shown discolored.
- the number of initial measurements is, for example, a predetermined number of measurements which can be expected in an evaluation device of a certain type with certain batteries, which is set up for carrying out the method according to the invention.
- the present invention is applicable both to evaluation devices with user-replaceable batteries and to evaluation devices whose batteries can only be replaced at the factory or by customer service. In the former case, however, the effort to achieve a reliable remaining useful life is higher.
- the term battery means any energy carrier which can be inserted or installed in an evaluation device and which makes it possible to operate the evaluation device independently of the mains. This not only includes batteries that can be used only once, but also chargeable batteries, so-called accumulators. In view of the low self-discharge rate, button cells or RAM cells are preferred, for example.
- FIG. 1 shows a first remaining service life display according to the invention
- FIG. 2 shows a second remaining service life display according to the invention.
- a display type with a plurality of segments 10 is preferably used, as is e.g. is known for fuel gauges in vehicles.
- the number of colored segments thus gives the user a forecast of the remaining service life.
- Each segment symbolizes e.g. 50 or 300 more measurements possible with the evaluation unit.
- Fig. 1 shows a linear arrangement of six rectangular segments 10.
- Fig. 2 shows a modified arrangement of six three- angular segments 10. The number of measurements that can still be made can also be displayed in other ways, for example as a number.
