Definitions
- the invention relates to a device for the single administration of medicinal substance for medical treatment.
- the invention relates to a drug delivery device for self-medication.
- Devices for the single administration of medicinal substance include, for example, prefilled syringes or cartridges. These are often combined with auto-injectors so that patients are able to independently apply the drug from the pre-filled syringe or cartridge. Auto-injectors are available in an electronic version with a motor or in a mechanical version.
- Electronic auto-injectors which include systems for tracking the use of the auto-injector. These systems collect and store data relating to the time of use, duration of application, amount of drug applied and other possible data. If necessary, the data is also analyzed and communicated to other devices. Or additional devices are proposed that are connected to the auto-injector in order to collect the corresponding data and possibly support the user in taking it, for example through a reminder functionality that sends a signal to the user when a certain non-use time is reached .
- WO2019 / 032784 A1 discloses, for example, a drug delivery system for a prefilled syringe with an adapter that is attached to the drug delivery system and reads information from a magnetic sensor.
- the magnetic sensor is attached to the drug delivery system housing or adapter.
- the drug delivery system includes a plunger that pushes the drug out of the prefilled syringe.
- a permanent magnet is attached to this piston.
- WO2018 / 195270 A1 discloses a method for tracking the use of an auto-injector by a patient and a corresponding external electronic adapter that can accommodate the auto-injector.
- the electronic adapter has a magnetic field sensor that detects the magnetic field of a magnetic element that is located on a movable component of the auto-injector. What all these systems have in common is that they are electronic and battery-operated. In some cases, the usage status is determined using magnetic field sensors that measure a different magnetic field depending on whether two components have moved relative to one another. If there has been movement, it is assumed that the administration system has already been used.
- the object of the present invention is to provide a system for recognizing the usage status for devices for the one-time administration of medicinal substance, the system not having any electronic components.
- the object of the invention is achieved in a device for the single administration of medicinal substance.
- the device can be a pre-filled syringe or an auto-injector into which a cartridge or a pre-filled syringe, each of which can also be needle-free, is inserted.
- the device according to the invention can also be a syringe without a needle or a portable device such as a patch pump.
- Devices consisting of a syringe and an additional element or adapter are also conceivable. It is crucial that there is a first component and a second component and that the second component is movable relative to the first component. In the following, the first component is referred to as the “housing”.
- housing includes, for example, a syringe body, an additional element fastened to the syringe body or a housing of an auto-injector that is suitable for receiving a prefilled syringe or a cartridge (optionally also without needles).
- the housing of other mechanical injection systems is also included in the term “housing”.
- the second, movable component can be a tip piston or the piston of an auto-injector.
- Other movable elements of an auto-injector such as a drive spring or a needle shield can also be used as movable components, provided that these elements experience a sufficiently large spatial displacement relative to the housing when a drug is administered.
- the device according to the invention for the single administration of medicinal substance has a housing and a second component which is arranged movably relative to the housing.
- the second component changes from a first position relative to the housing into a second position relative to the housing.
- a first magnetic element is fixed to the housing and a second magnetic element is arranged on the movable component. In the first position the first magnetic element and the second magnetic element are close to one another and in the second position they are The first magnetic element and the second magnetic element are spatially separated from one another, so that the magnetic field at the location or in the near field of the first magnetic element is greater when the movable component is in the first position than when the movable component is in the second position.
- Another embodiment of the device according to the invention for the single administration of medicinal substance has a housing and a second component which is arranged movably relative to the housing.
- the second component changes from a first position relative to the housing into a second position relative to the housing.
- a first magnetic element is fixed to the housing and a second magnetic element is arranged on the movable component. In the first position the first magnetic element and the second magnetic element are spatially separated from one another and in the second position the first magnetic element and the second magnetic element are close to one another, so that the magnetic field at the location or in the near field of the first magnetic element is smaller when the movable component is moving is in the first position than when the movable component is in the second position.
- Each magnetic element produces a magnetic field.
- the strength M of magnetic fields decreases with increasing distance R from their origin according to the relationship M (R) ⁇ 1 / R 2 .
- the magnetic field strength at a location is made up of the magnetic field strengths of all sources of magnetic fields that act at that location.
- the more distant magnetic field sources contribute little to almost nothing to the total magnetic field strength in relation to the magnetic field sources located close to the location. For this reason, a significantly higher magnetic field is measured at a location or in its near field where two magnetic field sources are close to each other than when only one of the two sources is located there and the second source is located at a location further away .
- first and second magnetic element for the device for example, a permanent magnet or magnetic particles, which are each fastened to the surface of the housing or the movable component, are enclosed in or between housing parts or parts of the movable component, in the material of the housing or the movable component are integrated or are part of a label applied to the housing or the movable component.
- the first and the second magnetic element preferably have the same magnetic characteristics, that is to say, for example, they are both permanent magnets made of the same material (NdFeB, bismanol, ferrites) with the same magnetic field strength.
- the measurement of the magnetic field strength at a predetermined position on the device according to the invention takes place with the aid of a magnetic field sensor which is not part of the device for the single administration of the medicinal substance.
- Typical magnetic field sensors are Hall sensors.
- the Magnetic field sensor is part of a separate device that has the functionality of a computer.
- the position at which or in the vicinity of which the magnetic field strength is measured is preferably marked on the outside of the housing. Another possibility of identification is an indication of the local area of the measurement via an interface of the separate device to the user (graphical user display or similar) or an instruction manual.
- the separate device has at least the following characteristics: a. a magnetic field sensor connected to a processor, the processor being connected to a memory and an interface to the user or a communication interface; b. In the memory, value ranges for magnetic fields are stored which correspond to a strength range of a magnetic field of a single magnetic element and value ranges for magnetic fields are stored which correspond to a strength range of the total magnetic field of two magnetic elements; c. a usage status is assigned to each of the two value ranges in the memory; d.
- the processor is programmed in such a way that it compares a measured value from the magnetic sensor with the stored value ranges for magnetic fields and, if the measured value matches one of the stored value ranges, sends a signal via the interface to the user or via the communication interface that corresponds to the usage status to which the corresponding one is used Value range is assigned.
- Correspondence between the measured value and a stored value range means that the measured value is on or within the limits of the value range.
- the range of values can also consist of one or more individual values.
- the separate device can be a conventional smart phone, tablet computer or a smart watch, etc., provided they have a magnetic field sensor, e.g. a Hall sensor. This is the case, for example, if the device has a compass function.
- Devices such as a smart phone or a smart watch are known to include the functionalities of a computer as standard. Via the interface to the user, for example via a display, icon, loudspeaker, audio output, the user can be given an optical, visual, haptic (vibration) signal that corresponds to the status "used" or "unused". A signal can be sent to another digital (end) device via the communication interface.
- the processor can also be programmed using an application that is loaded onto the separate device.
- the invention also relates to a computer-implemented method, comprehensive the steps
- the invention also relates to a computer program product comprising the commands which, when executed by a computer connected to a magnetic field sensor, cause the computer to carry out the following method steps
- the computer program product can be an application for a smart phone, tablet computer or a smart watch, etc.

- FIG. 1 and 2 show an auto-injector 100 with a housing 101 which has a proximal end 102 and a distal end 104.
- a cartridge with a cannula or a finished syringe / prefilled syringe (both not shown) can be inserted into the housing 101.
- a piston rod 110 movably mounted in the housing 101 parallel to the longitudinal axis of the housing can be moved from an initial position (FIG. 1) in the proximal direction to an end position (FIG. 2).
- the plunger rod 110 is in contact with a stopper 212 and presses on the stopper 212 of the pre-filled syringe or cartridge during application.
- FIG. 3 and 4 show the auto-injector 100 with a first magnetic element 310 and a second magnetic element 320.
- the first magnetic element 310 is located on the inner wall of the housing 101 in the region of the proximal end of the viewing window 120.
- the second magnetic element 320 is on the
- the piston rod 110 is fastened in the transition area to the stopper 212.
- the piston rod 110 with the second magnetic element can be seen in the area of the distal end of the viewing window 120.
- the auto-injector is unused, that is to say the piston rod 110 and the stopper 212 and thus the magnetic element 320 are located in a more distal position away from the first magnetic element 310.
- FIG. 4 the auto-injector has been triggered and the piston rod 110 has moved from a more distal position to a more proximal position.
- the piston rod 110 and the stopper 212 and thus the magnetic element 320 are now close to the first magnetic element 310.
- FIGS. 5 and 6 show the associated magnetic fields 330, 340 on the basis of magnetic field lines. It is indicated schematically that the strength of the magnetic field of a single, separate magnetic element 310, 320 (Fig. 5) is smaller or falls below a certain value at a smaller distance from the magnetic element 310, 320 than the magnetic field strength of two magnet elements located close together ( Fig. 6). This effect is used when determining the status “used” or “unused”.
- the device with the magnetic field sensor is a smart phone.
- the smart phone contains a compass and is therefore suitable for detecting magnetic fields.
- An application that has been loaded into the smartphone controls the measurement of the magnetic field strength with the magnetic field sensor and the processing of the measured values.
- the measurement of the magnetic field strength takes place on or in the vicinity of a marking 350 on the housing 101 of the auto-injector 100.
- the first magnetic element 310 is more likely on the inside of the housing 101.
- the display of the smart phone is attached to the marking 350 in the area of the Housing 101 or brought into the vicinity of the housing 101 of the auto-injector 102 and the value of the magnetic field Mc is detected.
- the marking 350 indicates to the user exactly where on or in the vicinity of the housing 101 the smart phone with its display is to be placed. It is important to carry out each measurement of the magnetic field strength within a certain close range to the location of the first magnetic element 310 so that the measurements can be compared. Instead of the display, another predetermined part of the smart phone can also be brought into close proximity to the marking 350 for measurement.
- the marking 350 on the housing 101 can be, for example, a marking on the outside of the housing 101 or an affixed label.
- value ranges [Mi correspond. Strength range because there can be a certain spread in the measured values depending on the distance of the magnetic field sensor from the magnetic element 310.
- value ranges [M 3 .... M4] for magnetic fields were stored in the memory of the smart phone, which correspond to the strength range of the added magnetic field of the magnetic elements 310 and 320 when these are close to one another.
- the application programs the processor of the smart phone in such a way that it reads the measured value Mc of the magnetic field sensor with the stored value ranges [Mi .... M2] and [M3 .... M4] for magnetic fields. If the measured value Mc is in one of the stored value ranges [Mi .... M2] or [M3 .... M4], the smartphone sends a corresponding signal to the user. For example, the word “Already used” can appear on the display if the measured value Mc is in the value range [M3 .... M4], or the word “Not used” if the measured value Mc is in the value range [Mi. . . . M2] lies. Alternatively, when the measured value Mc is in the value range [M3 .... M4], the smart phone can begin to vibrate as a sign of "used” and when the measured value Mc is in the value range [Mi .... M2] lies a triad. Many variants are conceivable here.
