Definitions
- the present invention relates to the field of fluid drug delivery devices, specific implementations of these delivery devices with wireless communication function.
- So-called smart devices such as smartphones, tablets or smart watches have become indispensable in today's world. Medical devices such as infusion pumps, which today send data to and receive data from other devices, are also becoming smart. For example, the Ypsopump from the manufacturer Ypsomed sends administration histories to smartphones and computers via a Bluetooth connection.
- Radio remote controls for infusion pumps have been known for a long time, examples being the OmniPod system from the manufacturer Insulet and various models from the manufacturer Medtronic, with the Medtronic models having this functionality for more than 20 years.
- Remote control via a smart phone app is new, such as that made possible by the manufacturer Sooil with the AnyDana app for its DanaDiabecareRS insulin pump. With the new control options, new risks also arise.
- radio remote control it must be ensured that no third party can hijack the radio remote control function.
- the remote control is a smart phone
- a third party can either try to install an additional app on the smart phone that hijacks the function, or they can try to hack the official remote control app. Under certain circumstances, the third party can also simply try to extract sensitive therapy data from the app.
- a third party can also eavesdrop on the radio communication or gain direct access to the infusion pump via a third-party device, for example as a "man in the middle" or as a separate remote control.
- Radio connections between the remote control and a medical device must be secure.
- the data which may be stored on the remote control, must be stored securely.
- the secure radio connection between the remote control and the medical device must be established in a secure manner.
- the present invention deals with the solution of the last-mentioned problem.
- EP 3716567 A1 discloses methods for securely establishing a secure wireless connection between a medical administration device and a mobile device with an app.
- the connection to be established is a Bluetooth connection, whereby the data transmitted between the app and the administration device is encrypted end-to-end by the app and the administration device.
- the data is also encrypted by the Bluetooth system.
- the administration device's public key, which is used for end-to-end encryption, is not transmitted via the Bluetooth connection, but separately via a different connection in order to prevent the key from being intercepted via the Bluetooth connection.
- the disadvantage of this method is that in addition to the Bluetooth connection, another connection technology such as NFC is required.
- a method is known from US20140206288 A1 for performing device pairing (for a radio connection) between two mobile devices, the mobile devices being moved together. This involves establishing a connection between two devices, which allows secure transmission of data from device to device. However, the data within the devices can still be tapped.
- a medicament in the present context includes any flowable medicinal formulation which is suitable for controlled administration by means of a cannula or hollow needle into subcutaneous or intramuscular tissue, for example a liquid, a solution, a gel or a fine suspension containing one or more active medicinal ingredients.
- a medicament may be a single active ingredient composition or a premixed or co-formulated multiple active ingredient composition from a single container.
- medicines such as peptides (e.g.
- insulins insulin-containing medicines, GEP 1-containing and derived or analogous preparations
- proteins and hormones proteins and hormones
- biologically derived or active substances substances based on hormones or genes, nutritional formulations, enzymes and other substances in solid (suspended) or liquid form.
- the term also includes polysaccharides, vaccines, DNA or RNA or oligonucleotides, antibodies or parts of antibodies as well as suitable base materials, auxiliary materials and carriers.
- distal refers to a side or direction directed toward the front, puncture-side end of the administration device or toward the tip of the injection needle.
- proximal designates a side or direction directed toward the rear end of the administering device opposite the end on the puncture side.
- injection system or “injector” mean a device in which the injection needle is removed from the tissue after a controlled amount of the medicinal substance has been released. So stays with one Injection system or, in the case of an injector, in contrast to an infusion system, the injection needle does not remain in the tissue for a longer period of several hours.
- the invention relates to a method for establishing a secure connection for transmitting data between a medical device system and a mobile device.
- the medical device system can be configured in one or more parts.
- the medical device system can be a one-part or multi-part administration device for administering a medicament, in particular a fluid or liquid medicament.
- the mobile device can in particular be a mobile phone, specifically a smart phone. The method comprises several steps.
- the medical device system and the mobile device are put into a mode in which a new, secure connection can be established between the medical device system and the mobile device.
- a wireless connection for data transmission is established between the at least one part of the medical device system and the mobile device, this connection being non-secure within the meaning of the invention.
- this can be a Bluetooth Just Works connection.
- NFC, WLAN, ZigBee, EnOcean or similar protocols would also be possible.
- the non-secure connection between the at least one part of the medical device system and the mobile device can also be encrypted.
- not-safe means that the connection does not ensure that the correct medical device system is connected to the correct mobile device.
- other devices can intervene in the non-secure connections and intercept the communication. In the case of non-secure connections, it is also not certain which software or application on the mobile device (or more theoretically in the medical device system) is exchanging data with the corresponding other party.
- the mobile device and the at least one part of the medical device system are moved together. This can be done, for example, by a user holding the mobile device and the at least part of the medical device system together in one hand and then moving the hand.
- both the mobile device and the at least one part of the medical device system each generate information.
- the information generated is based at least in part on the movement that is carried out.
- the at least one part of the medical device system and the mobile device use the information they have generated themselves and the information fragments transmitted by the respective other device to establish a secure connection between one another.
- keys can be generated on the at least one part of the medical device system and on the mobile device, which keys can be used for end-to-end encryption of the data transmission. Since the mobile device and the at least one part of the medical device system that is moved can recognize the same movement pattern due to the joint movement, it is possible to generate secret keys via the movement, which are identical and therefore do not have to be exchanged. This also means that eavesdropping is no longer possible, and the connection is therefore secure within the meaning of the invention.
- the method described in this aspect has the further advantage, for example, that due to the joint movement, the information fragments transmitted by the mobile device, or at least part of the medical device system, can be clearly assigned to the other device, since the movement is joint and therefore is simultaneous and can therefore be generated by analogue information.
- the invention can also be used to ensure an end-to-end secure connection for data exchange at the application level.
- the information generated on the mobile device and on the at least one part of the medical device system comprises identification data that is permanently stored in addition to the movement data that is continuously generated. With these it can device type, serial number, software version, public keys for data encryption or similar information.
- the at least one part of the device system that is moved obtains data from another part of the device system before the movement, which data then flows into the generated information.
- the medical device system is a combination of an administration device and an add-on with electronics.
- the add-on is to be seen as an additional device which can be connected to the administration device and which can flexibly supplement the administration device with additional functions.
- the add-on can be used with several administration devices at different times, which has the advantage that, for example, an administration device can be designed as a disposable device without electronics and the add-on can be designed with electronics, so that electronic waste can be reduced.
- the add-on can assume the role of at least one part of the medical device system and be moved together with the mobile device in order to set up the secure connection.
- Add-ons for administration devices are known to the person skilled in the art, for example, from EP 3572107 A1, EP 3519021 A1 or EP 3538183 A1. All three publications are hereby fully incorporated by reference into the present application.
- the at least one part of the medical device system and the mobile device are not only moved together, but always at the same time and in the same direction. This has the advantage that the evaluation of the transmitted information can be made easier.
- the at least one part of the medical device system and the mobile device are held together for movement. For example, they are placed one on top of the other before the movement by the person using them and then grasped with one hand, so that both the at least one part of the medical device system and the mobile device form a kinematic unit for the movement.
- the at least one part of the medical device system and the mobile device can be temporarily and detachably attached to one another in an advantageous embodiment. This can be done, for example, via an adhesive or Velcro connection.
- a separate auxiliary device can also be used, with which the at least one part of the medical device system and the mobile device can be attached to one another.
- the accessory may include clips or snaps for attachment.
- at least one part of the medical device system and the mobile device each comprise at least one motion sensor.
- a motion sensor means a component with which a change in position is converted into an electrical variable that can be evaluated with suitable electronic wiring. Any type of acceleration sensor (such as inertial measurement units, gyro sensors, accelerometers) also falls under the term motion sensor, as is used for the present invention.
- the wireless communication device of the mobile device includes a Bluetooth unit.
- the electronics of at least one part of the medical device system also includes a Bluetooth unit.
- the Bluetooth units are used for the wireless transmission of data between the mobile device and the at least one part of the medical device system.
- at least part of the medical device system can be an add-on as described in the publications EP 3572107 A1, EP 3519021 A1 or EP 3538183 A1, to which the functionality according to the invention has been added.
- a Bluetooth Just Works connection can be set up as a non-secure connection, which then enables the fragments to be transmitted between the mobile device and the at least one part of the medical device system.
- a conventional Bluetooth connection with code input can be set up to set up the non-secure connection.
- Various possible variants that meet the Bluetooth specification see also https://www.bluetooth.com/specifications/, Bluetooth Special Interest Group) are well known to those skilled in the art.
- the medical device system can be accompanied by a code that is entered in the mobile device for the purpose of setting up the non-secure connection (in the context of the invention).
- additional information can be exchanged via NFC (Near Field Communication) to set up a non-secure connection.
- NFC Near Field Communication
- keys for setting up an encrypted Bluetooth connection between the mobile device and the at least part of the medical device system can be exchanged via NFC. This has the advantage that it becomes more difficult to intercept the keys.
- the invention relates to a medical device system.
- the device system can be used to carry out a method according to the invention.
- the medical device system can be designed in one or more parts.
- Multi-part can also mean a modularly constructed device system—as already described above, a system consisting of an administration device and an add-on or also a modularly constructed administration device.
- the administration devices can be injection pens, auto-injectors, patch injectors, pre-filled syringes (so-called pre-filled syringes), infusion pumps, special insulin pumps, patch insulin pumps or similar devices that can be used for self-administration of fluid or liquid medication.
- the mobile device can be a mobile phone or a smart phone. According to the invention, however, so-called personal digital assistants (PDAs) without telephone functionality can also be used. Furthermore, according to the invention, remote controls for the administration devices are also intended as mobile devices. Smart watches, tablets or notebooks are also included.
- 1a shows a medical device system in the form of an injection pen
- 1b shows a mobile device in the form of a smart phone
- Fig. 2 shows the mobile device and the medical system (injection pen) during the movement according to the invention by a user (symbolized by the drawn hand)
- Figures 1a to 2 show an example of a medical administration system in the form of the injection pen 1 and a mobile device in the form of a smart phone 2.
- the injection pen 1 is an example of the administration system it can also be an infusion system or another system described above.
- the Smart Phone 2 is also just an example, instead a tablet, notebook or smart watch could also take over the function.
- the injection pen 1 basically works like classic injection pens, which are well known to those skilled in the art (examples: Novopen 5 from Novo Nordisk, HumaPen Memoir from Eli Eilly or the UnoPen from Ypsomed).
- the injection pen 1 has a dosing element 1a, on which a dose to be administered can be set. A set dose will be indicated by means of the dose display 1b.
- an injection needle can be detachably attached (not shown), through which a fluid medicament can be administered in accordance with the set dose.
- the electronic elements are arranged inside the injection pen 1 and are supplied by a suitable energy source (as mentioned above, the electronics could also be outsourced to an add-on).
- the electronic elements comprise at least a movement sensor and a communication device, both of which are connected to one another via a suitable control element, such as a controller or processor, and are controlled and monitored via the control element.
- the communication device is used for wireless communication with the smart phone 2.
- the controller is at least designed to receive measurement data from the motion sensor, to process this information and to transmit at least parts of it to the smart phone 2 via the communication device.
- the control element is designed to receive information fragments from the communication device, which are transmitted from the smartphone 2 to the injection pen 1 .
- the communication device is a Bluetooth module.
- NFC, WLAN and other technologies are also suitable.
- the Smart Phone 2 has the typical features of smartphones that are well known to those skilled in the art from models such as the Samsung S10 or the Apple iPhone 11.
- the smart phone 2 also has, among other things, at least one movement sensor, various communication devices, such as a mobile network, Bluetooth and/or NFC, and a powerful control and data processing device.
- apps As usual on smart phones, different software applications, so-called apps, are also installed on smart phones.
- a specialized app (not shown) serves as the endpoint for secure data transmission between the injection pen 1 and the smart phone 2. This means that data that is securely transmitted from the injection pen 1 to the smart phone 2 is only converted into plain text in the specialized app .
- the specialized app represents a secure container for the data, so that other apps installed on the smart phone 2 do not have access to the data in the container.
- Data that is not currently being displayed in the app or is being processed in any way is preferably stored in encrypted form in the app container.
- the app can be deactivated or deleted from a remote server, which is advantageous, for example, if the smart phone has been stolen.
- the app can not only be used to receive or send data to the injection pen.
- the app can also be a health management app that has the features according to the invention have been added.
- management apps are known to those skilled in the art, examples are SiDiary from Sinovo or mySugr from mySugr. Due to the secure communication according to the invention, a remote control function can be added to the app in further advantageous developments, so that the injection pen 1 (or more generally the medical system) can be remotely controlled via the specialized app.
- Figure 2 shows schematically an inventive method for establishing a secure connection for transmitting data between the injection pen 1 and the smart phone 2.
- the user (shown schematically by the hand 3) puts both devices in a coupling mode in which the structure a connection is possible.
- Injection pen 1 and smart phone 2 then automatically (or with the intervention of the user) establish a wireless connection, which is not yet considered secure within the meaning of the invention. In this state, however, data can be exchanged between the injection pen 1 and the smart phone 2 .
- the Just Works connection establishes an encrypted, wireless connection between the injection pen 1 and the smartphone 2. Although this connection is encrypted as mentioned, it is not secure within the meaning of the present invention.
- the data is decrypted after receipt in the Bluetooth unit of the Smart Phone 2 and not in the dedicated app provided for this purpose. This means that there is a possibility that another app can access the decrypted data.
- the user grasps both devices with hand 3 and moves them together, which is symbolically represented by arrow 4 in FIG.
- the movement may be arbitrary, whereby a certain minimum amount should not be undershot so that a sufficient measurement signal (ie a sufficiently large amount of measurement data) can arise.
- the movement sensors in the injection pen 1 and the smart phone 2 generate measurement signals which are accepted and processed by the control element of the injection pen 1 or by the control and data processing device of the smart phone 2 . Since the two devices are held together in the hand 3, the sensors measure comparable movement patterns, also in terms of time.
- the measurement signals are processed into information in the injection pen 1 and smartphone 2, which is also comparable.
- the specialized app in the Smart Phone 2 processes the measurement signals into information.
- the information generated in this way or fragments thereof (on injection pen 1 and smart phone 2) can be exchanged and compared between the devices.
- the comparison can be used for mutual identification and authentication of smart phone 2 and injection pen 1. Since only the smartphone 2 and the injection pen 1 are moved at the same time and in the same way, the risk of confusion with third-party devices or the possibility of hacking by third-party devices is minimized.
- the information generated from the movement can also be used to create keys.
- algorithms can be stored on the injection pen 1 and the specialized app of the smartphone 2, which generate a key from the information.
- an identical key can be generated on both devices, with the keys being checked by mutual challenges (encryption and decryption of test information, checksums or hashes).
- key pairs can also be generated. The person skilled in the art is familiar with the typical and established cryptographic methods.
- the information is checked by continuously processing the movement into information and constantly exchanging information (fragments) between the smartphone 2 (especially the specialized app) and the injection pen 1 and for identification, authentication and/or final end-to-end encryption is used.
- the connection can be made even more secure by comparing information or information fragments from a number of movement fragments.
