说明书全文 | The present invention relates to a programmable device, comprising a programmable electronic circuit, an electrical power source and an alert body controlled by the electronic circuit, wherein the electronic circuit includes at least a computer interface, a real time clock and a programmable memory. One such device is known from Other such devices are known from The invention aims to provide a device for signaling a time tied activity enabling, at multiple times, the issuance of a signal according to a pre-determinable pattern. This objective is achieved by a device according to claim 1. For example, at the time the medicines are given to the patient, the device is programmed by the prescribing doctor or pharmacist and stuck on the medicine container. The programming activity takes place by means of a personal computer (PC) or a similar device with is connected through the computer interface to the device of the invention. Through programming, a set of alert times at which the medication should be taken, are stored in the device. At any time there is a next alert time that, at that moment, is the relevant signaling time. This applies until the last programmed alert has been handled. As long as the relevant alert time has not yet been reached, the alert device issues a first signal, indicating that no medicines should be taken. When the relevant alert time is reached, the device issues a second signal. This signal notifies the patient that the time for taking the medication has been reached. Immediately after taking the medication, the patient operates the switch, after which the second signal is deactivated and a new relevant alert time is determined and set as programmed. The alert body is now signaling the first signal until the next relevant alert time has been reached, after which the device changes the signal to the second signal. This process can be repeated as often as desirable. The number of times this process is repeated is determined by the programming. The device with just one switch and the ability to issue two different signals is very user friendly and easy to operate. Preferably, the first signal switches off when the device activates the second signal. This way, a double indication is realized that informs the patient in what the part of the scheduled medicine intake system one is situated. Before a scheduled alert time, the first signal is active while the second signal is not active. When the relevant alert time is due, the first signal is deactivated, and the second signal is activated. Since the first signal is different from the second signal, a redundancy is built in that increases the ease of use and reduces the chance of incorrectly taking the prescribed medication significantly. In a very simple implementation of the invention, a number of signaling times are determined by means of the PC and then transferred to the memory of the device. It is however also possible that the device is programmed via the PC with parameters that are set by the doctor / pharmacist to follow the desired course of drug intake. This way, almost every intake pattern is feasible with the device according to the invention. For example, the daily or weekly dose can be made dependent on the time at which the user takes the medication. During an initial phase, the dose can be gradually increased whilst the dosing can be gradually reduced during the final phase of the intake schedule. The degree of change in the dosage during initial phase and the final phase can preferably be set with a limited number of parameters, or even a single parameter that is set by the doctor / pharmacist. In a very simple and economic implementation, the switch is a push-button switch and the alert body is a LED (Light Emitting Diode). The switch may alternatively be implemented as a touch-operated switch. The first signal from the LED could be a slowly flashing signal and the second signal a fast blinking signal. In this implementation it is possible to use a two-color LED, so the first and second signal have a different color. In this implementation, the invention is not only user friendly, easy to read and easy to use, but can also be made very compact. In a preferred implementation of the device according to the invention, the alert body comprises two LEDs, each of a different color, for example, a red and a green LED. This way, the first signal could for example consist of the red LED flashing with a certain interval. This is the sign that the device is activated, so the program runs, but the relevant alert time has not yet arrived. This tells the user that the device is in operation, but that the prescribed drug intake time has not yet arrived. At the relevant alert time, the red LED turns off and the green LED starts to flash. This is the signal for the user that the drug should be taken. After taking the drug, the user presses the button and a new alert time is determined according to the imported alert times or according to the entered parameters. In a preferred implementation of the device according to invention, the time at which the switch is operated, and hence the intake time, is stored in the device's memory. This way, the time of intake can be read out by the doctor on a PC. This allows the doctor to get insight in the level of compliance of the patient. In another preferred implementation of the device according to the invention, the nature of the signs changes while the user fails to respond to the alert signal that an act must be performed. For example, the green LED could start flashing more rapidly and ultimately be continuously lit. In a preferred implementation of the invention, the alert body is capable of issuing an audible signal, e.g. by means of a piezo-electric buzzer, that can be activated in the event that some time after the expiry of the relevant signaling time, the button still has not been pressed. In that case, the speaker could be useful as a means of drawing the attention of the user. In a preferred implementation of the device according to the invention, the device includes a RFID (Radio Frequency IDentification) chip, or a wirelessly programmable RFID chip. However, other usual communication means may be included in the device according to the invention, e.g. infrared communication, Bluetooth, Near Field Communications (NFC) or cable communications. The device according to the invention has a prolonged lifespan if the power source is rechargeable. Preferably, the charging is contactless, for example inductive, or by means of a solar panel. For increased security, access to the device for programming and readout of the memory can be protected by a code. To avoid confusion, a readable identification can be both printed on the device and stored in its memory. In addition, the user friendliness is increased when simple instructions such as the meaning of the signals, are shown on the substrate of the device. The device can be built out of mainly thin and flexible components. This will allow the device to be attached to objects of many different shapes. An implementation as a sticker has special preference. The device can then for example be attached to medication bottles or pillboxes, etc., of almost any shape and size. The invention will now be further illustrated by a description of an example of a preferred implementation of the present invention, with reference to the attached drawings, in which
In Apart from entering medication intake times, other useful data can be stored in the memory of the device according to the invention and/or may be entered by the doctor/pharmacist via the PC, such as
After the programming has been completed, microprocessor 3, as a result of the schedule that was programmed, will control the red LED 6 in such a manner that it flashes with a slow interval. This is a sign that the device is programmed and thus activated, but that the medicine intake time has not yet arrived. When the time has arrived to take the medicine, then LED 6 turns off and thus stops flashing, and the green LED 7 starts to flash slowly. If the user sees this, he/she knows that it is time to take the medicine, and that the user should operate push button 8 while taking the medicine. If a predetermined time expires and the user has not yet taken the medicine, then the green LED 7 flashes with gradually increasing speeds until finally green LED 7 is lit continuously. What happens when the user forgets to take the medicine depends on the prescription of the physician or pharmacist. It may be set so that green LED 7 is lit until the medicine is taken and the push button is pressed, but it may also be advantageous for a certain medicine to skip this intake. In this case, after some time the green LED 7 shuts down and a new intake time is determined. Until that time the red LED 6 flashes again. There has been no record of intake (see below) and this skipping by the user is can later be observed during a read-out by the physician / pharmacist. If the user has taken the medicine on time, he/she presses button 8 and the device 1 stores the time of intake into memory 4 and sets a new intake time. The green LED 7 is turned off and the red LED 6 flashes slowly again. A new cycle has started. If desired, the physician / pharmacist can read out the intake time data through the programming unit. An embodiment of a device 1 according to the invention could feature an alert body that, besides control LEDs 6 and 7, could also issue an audible signal, eg by means of a (not shown) piezo-electric speaker, or it could be equipped with the ability to send signals to an external device, for example, through Bluetooth or Near Field Communication (NFC). The user that carries the device equipped for Bluetooth communication or NFC with him, will always be warned of drug intake times, regardless of where they are relative to the device according to the invention, of course within reach of the communication system. Also by means of Bluetooth communication or NFC, external alert signs can be activated, such as an alert by a mobile phone or other device that is equipped with NFC. The devices according to the invention thus provide a simple solution for cases where several medicines with different intake schedules should be taken. The physician/pharmacist simply programs an individual device for each individual medicine, so the patient only needs to observe the relevant alerts. In hospitals and other healthcare facilities where the nursing staff is responsible for the intake of medication, the devices according to the invention are very useful. In particular, when they suddenly have to leave the patient because of an emergency call, it is easy to see which medication has been taken, and which medication has not yet been administered. Although the invention is extensively illustrated by examples related to ingestion of medicines, the invention is not limited to this application. The invention is equally applicable to other regular activities such as doing exercises etc. Nor is the invention limited to the implementation in the form of a thin flexible sticker. Versions in the shape of a bracelet, or attached to a bracelet, or as a pendant on a necklace, etc. are also possible. Likewise, the attachment by means of an adhesive layer serves only as a non-restrictive example of an implementation of the invention. Other fasteners such as magnetic attachment or fixtures are equally possible within the scope of the present invention. Also, the device according to the invention can be integrated, for example in the packaging of a product. LEDs are mentioned as an example of a signaling device, but also other signaling devices such as electronic paper, an LCD, an OLED, electro chrome displays, light emitting polymers, etc. are included within the scope of the invention as an implementation of the alert device. It is also possible for a device according to the invention to include signals that can have other meanings, such as a signal to indicate low battery voltage or a signal indicating that the intake regimen is poorly observed. Also, other useful data can be stored in the memory of a device according to the invention, such as data regarding the user, the prescribing authority, the prescribed medicine, etc. |
