(80) Optionally the data passed from drug delivery device 158 may for example include but is not limited to, drug delivery device identification, injection date and time stamp, dose delivered, drug identification, drug lot number, drug manufacturing details, delivered dose, type of drug, environmental exposure associated with the drug, type of delivery device used, time stamp of delivery, injection time length, location of injection or the like. Data related to the syringe 158 and its contents available on tags 158a-e provide for optimizing drug delivery to a user as well as providing detailed information to a user and/or optimizer 100 that may be identified as potentially problematic and/or hazardous to a user.
(81) For example, a user may confuse one injection type for another where instead of injection of basal insulin the user injects is about to inject bolus insulin, optimizer 100 most preferably may identify such situations and communicate to an optional user interface 128U (
(82) Optionally communication between auxiliary device 150 and device 100 may be facilitated with and or through mobile communication device 159. Optionally mobile communication device may be provided in optional forms for example including but not limited to PDA, laptop, smart phone, tablet or the like mobile communication device comprising a processing and communication capabilities. For example, a food analysis calculator 155 may be provided in the form of a software application running on mobile communication device 159 that communicates data relating to caloric calculation to device 100 to at least one of base station 130 or reusable unit 120.
(83) Optionally mobile communication device 159 may facilitate communication and entry of optional offline data 210 to device 100 to at least one of base station 130 or reusable unit 120. For example, offline data 210 may for example include but is not limited to laboratory tests, a user's medical history or the like data that may play a role in the systemic insulin metabolic pathway affecting the homeostasis between glucose levels and insulin levels.

(86) First in stage 1100 a drug delivery optimizer 100, 101, 105, 100P is coupled to a user defining a bolus drug delivery injection site 112 over a user's skin surface. Next in stage 1101, prior to an expected meal time bolus injection user checks blood glucose levels with a blood glucose monitor 151. Optionally and preferably blood glucose monitor 151 is synchronized and in communication with reusable unit 120, for example, via communication module 128C. Next in stage 1102, reusable portion 120, stores the blood glucose reading from stage 1101.
(87) Optionally and more preferably in parallel to meal event the user prior to food intake the user utilizes a food analyzing device and/or calculator 155 and dose calculator 153 to determine both the caloric value of the meal and the required insulin does based on the expected meal content and caloric value, as shown in optional stages 1110 and 1111. Finally in optional stage 1112 the calculated dose is communicated to unit 120. Most preferably when expected dose is communicated to device 100, 101, 105, 100P its reusable unit 120 can store the information of what dose and insulin type to expect in the bolus injection. Furthermore, device 100 most preferably may utilize the data to determine the optimization scheme required, to most effectively drug delivery by way of controlling the appropriate treatment element 122, for example including heating element 122h.
(88) Next in stage 1103, reusable unit 120 detects meal event most preferably via sensor module 120S and in particular through meal detection sensor 126. Optionally meal detection may be further provided by way of communication with an auxiliary meal detection device 154. Most preferably once meal event is detected, reusable unit 120 records the meal event with a time stamp. Optionally and preferably in stage 1103 unit 120 further obtains expected insulin dose based on the detected meal and/or blood glucose levels measured in stage 1102.
(89) Next in stage 1104 once meal has been detected unit 120 awaits detection of a bolus injection. Most preferably bolus injection is most preferably detected by the change in configuration of unit 120 for example with activation pin 118 providing for detecting closed or open configuration of optimizer 100 where reusable unit 120 is opened relative to disposable unit 110. For example, in preparation for a bolus injection, unit 120 is opened therein activation pin 118 is disengaged from recess 128a, following injection unit 120 is closed onto disposable unit 110 therein reengaging activation pin 118 and recess 128a indicating that optimization may begin and/or continue about the injection site 112.
(90) Accordingly in stage 1105 optimizer 100 awaits for bolus injection, if such a bolus injection is not detected within a given time frame an optional reminder may be provided, in stage 1106.
(91) Next in stage 1107, optimizer 100 detects a bolus injection with a syringe based drug delivery device. Most preferably syringe based drug delivery is detected with contactless communication between module 128R and a syringe or injection pen 158 comprising corresponding electronics, for example a RFID tag, as previously described, shown in
(92) Next in stage 1108 the data associated with the injection communicated in stage 1107 is confirmed to ensure that the proper drug type and dose was actually delivered to the user. Optionally and most preferably if any problems are identified due to mismatch of dose and/or drug type relevant communication is initiated from unit 120 most preferably through communication module 128T, optionally to a HUB 160 or mobile communication device 159.
(93) Next in stage 1109 following injection optimizer 100 optimizes drug delivery by activating, as necessary, treatment element 122 for example heating element 122h about the injection site 112. Optionally and preferably optimization is controlled relative to the data available to optimizer 100 for example with intrinsic sensor including physical activity sensor 124 and/or physiological sensor 123 for example indicative of local blood perfusion, impedance level with impedance sensor 127; and further optimized relative to external data communicated to optimizer 100, either directly (
(94)
(95) First in stage 1200 communication is synchronized between HUB 160 and device 100, 101, 105, 100P most preferably about reusable unit 120 and optionally about base station 130.
(96) Next in stage 1201 HUB 160 data from all available and linked AUX devices 150 as previously described.
(97) Next in stage 1202 HUB 160 monitors and integrates all data sources that relate to insulin metabolic processes.
(98) Optionally based on this data, in stage 1210, HUB 160 abstracts and learns and continuously updates a personalized drug delivery profile and/or user specific metabolic pathway associated with the drug. Optionally stage 1210 may be realized with dedicated learning algorithms, neural networks, fuzzy networks or the like artificial intelligence tools as known and accepted in the art.
(99) Next in stage 1203, based on data available to HUB 160 and local monitoring data provided by optimizer 100, determine any action to be taken to ensure continuous homeostatic levels of blood glucose levels, by a user or device linked and associated with HUB 160 for example including but not limited to auxiliary device 150 and optimizer 100.
(100) Next in stage 1204 the required action is communicated to the appropriated linked device optimizer 100 and/or at least one or more auxiliary device 150.
(101) Next in stage 1205, HUB 160 monitors action communicated in stage 1204 is performed or optionally alternates the action to be taken should a required action is not performed at all or in a timely manner.
