Definitions

  • Monitoring device for monitoring and displaying critical storage and transport conditions
  • the invention relates to a monitoring device for monitoring and displaying critical storage or transport conditions of perishable goods.
  • data loggers Other known methods use data loggers, the task of which is to continuously collect data and store it in a memory. With such data loggers, the data are stored chronologically in a memory and can be read out of the memory there in sequence. To analyze such data, it is transferred to a PC via an interface and evaluated there using a program. Instead of a PC, alternatives of such devices also use only one printer, on which the stored data are printed out in chronological order and thereby visualized.
  • Such data logger arrangements correspond, for example, to a flight recorder, a tachograph or a seismic or meteorological monitoring device known from a long time ago and recorded on a measuring strip, a measuring disc or the like. Such data logger arrangements therefore do not satisfy the problems according to (a) - (c).
  • Another data logger is shown in WO-A-99/26042.
  • this device also requires a PC and a special evaluation interface for evaluation, so that on its own it does not solve problem areas (a), (b) and (d) satisfactorily.
  • Another temperature data logger according to US-RE-36, 200 whose stored data must be read out via an electro-optical interface, can be compared to this device from the prior art in order to meet the requirements of (a), (b) and (d) satisfy.
  • the present invention is therefore based on the following object: To enable a clear and simple detection, calculation and display of the current state of perishability or the durability or aging of goods at any time.
  • the new device should also be able to be attached to any goods or their packaging without any problems and should be used preferably, if not exclusively, as a disposable device, as was the case with the known chemical display devices, which are disposed of after use or only for Documentation purposes.
  • the device is thus of a small, handy design, can be attached to any goods or their packaging and can be operated autonomously on the network. It has a display. All information regarding problem areas (a) - (d) is visibly displayed on the. This can be done, for example, by continuously showing how far the aging of the goods has progressed due to the temperature / time load, how long the goods would still be stable under the prevailing storage conditions, or whether and when events occurred that would make the goods more storable exclude.
  • the temperature / time relationship and the goods parameter are included in the calculation is carried out by a microprocessor inside the device, with the time and temperature being measured continuously from a defined start signal. According to the invention, the result of this calculation is continuously shown on a display without the need for an additional auxiliary program, an interface or an auxiliary device such as a printer, PC or the like.
  • the display shows how much of the freshness time has already expired or, if appropriate, how long the remaining shelf life is under the prevailing storage conditions.
  • events are displayed which, taken on their own, are already capable of ending the freshness or usability or further storage or transportability of goods depending on the time or independently. These are e.g. Falling below or exceeding a certain storage temperature over a certain period of time (e.g. 5mm storage time at a temperature below -5 ° C or 10mm storage time at a temperature of or above 43 ° C.
  • Parameters are recorded and displayed, such as moisture, gas pressures, shocks or vibrations, ionizing or non-ionizing rays, electrical or magnetic fields, chemical or biological, eg bacteriological influences.
  • alarm information can also be displayed or read acoustically or optically when a parameter is exceeded. If the storage conditions change in the course of time, the remaining shelf life shown is adapted in accordance with a special embodiment of the invention. When a predetermined end consumption limit is reached or when a certain parameter is exceeded, alarm information is also displayed.
  • the display comprises time segments which, by flashing, indicate when an alarm limit has been exceeded in the past.
  • the time of a fault can be determined retrospectively. This serves to clarify responsibility and preventively prevent such accidents in the future.
  • temperature is referred to as a parameter in this patent application, this is only an example, since the invention relates in principle to any parameters of interest to the user. These can also be, for example: moisture, pressure, all types of radiation, gas concentrations, etc. The invention is also not restricted to a specific application. Of course, monitoring devices according to the invention can also be used for monitoring rooms, works of art, animals or people, in order to collect, store and display the information required in each case.
  • the reference to "disposable device” does not mean that devices that are designed as reusable devices per se are excluded from the scope of protection or that they are also manipulated by certain manipulations that are normally not to be performed can be used a second or more times.
  • the device according to the invention is designed and constructed to be maintenance-free and tamper-proof for one-time operation. Following this unique measurement or monitoring operation, it should serve as a document for a certain period of time, in that the displayed memory values are retained indelibly and visibly.
  • the display should preferably also be capable of being photocopied, in order for the information content to also be faxed or the like. to make transferable.
  • the drawing relates to symbolic exemplary embodiments according to the invention.
  • the external shape of the device may be adapted to the corresponding needs, but in particular an approximately credit card-sized design is preferred.
  • the invention thus takes the form of an electronic, thinking label.
  • the device can also be subsequently validated (to fulfill the GLP -Good Laboratory Practice).
  • a test function is installed if required, which can be activated via a key combination (start / stop key) and e.g. a subsequent measurement in a climatic chamber allowed.

  • Fig.l shows the structure of a variant of the disposable device according to the invention with a housing made of two parts 1 and 3, a display (display) 2, a labeling field 4 for subsequent marking or assignment of the device to a specific product or a specific date, etc. , an electronic part with a microprocessor 5 or a specially designed semiconductor chip (dedicated chip) with a timer and a sensor, for example a temperature sensor, an energy source (e.g. a battery) 6 and with a start part (switch) 7 for emitting the start signal to the electronic part 5.
  • the display shows the elapsed time and the remaining shelf life by time segments 8. In addition, if corresponding events have occurred, the type of events and an alarm 9 can be displayed or issued.
  • the device is small and has a waterproof or water-repellent housing. Once the device has started, the information is retained even after a stop, which prevents tampering. Once started cannot be undone. If necessary and not shown in more detail, a more detailed readout option can also be included in the program of the electronic part, so that by pressing the start part in particular, detailed information can be queried from the memory - comparable to reading out information from a conventional data logger.
