WATERPROOF CASING FOR INSULIN PUMPS

Resumen de: WO2025175025A1

A casing for an insulin delivery system includes a housing, a lid, and a gasket. The housing includes a first overmolded rubber member defining a first channel part. The lid includes a second overmolded rubber member defining a second channel part. The lid is couplable to the housing to define an enclosure and a cavity.

The channel encloses a tubing to fluidly couple the insulin pump to an outside of the casing. The gasket is received between the housing and the lid to seal the housing with the lid, preventing fluid ingress into the cavity and the enclosure and providing a waterproof seal between the cavity and the enclosure when the lid is removably coupled to the housing.

AUTOMATIC MEDICAMENT DELIVERY DEVICE UTILIZING LIMITED OR NO USER INPUT

Resumen de: US2025262379A1

Exemplary embodiments relate to drug delivery devices, such as automated insulin delivery (AMD) devices. The described methods and apparatuses allow an AMD device to be initialized and/or operated with little or no user input. Exemplary logic initializes the AMD device to operate with known-safe drug delivery parameters that leverage the AMD device's ability to monitor blood glucose levels at short intervals and continuously deliver small amounts of insulin. The AMD then rapidly adapts the parameters and system constraints based on current and historical glucose measurements. Further embodiments provide for the detection of events that result in disturbances to glucose control, and to adaptation of alert frequency based on user behavior.

SYSTEM AND METHOD FOR PROVIDING ALERTS OPTIMIZED FOR A USER

Resumen de: US2025266143A1

Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

RETROSPECTIVE RETROFITTING METHOD TO GENERATE A CONTINUOUS GLUCOSE CONCENTRATION PROFILE

Resumen de: EP4603003A2

Continuous Glucose Monitoring (CGM) devices provide glucose concentration measurements in the subcutaneous tissue with limited accuracy and precision. Therefore, CGM readings cannot be incorporated in a straightforward manner in outcome metrics of clinical trials e.g. aimed to assess new glycaemic-regulation therapies. To define those outcome metrics, frequent Blood Glucose (BG) reference measurements are still needed, with consequent relevant difficulties in outpatient settings. Here we propose a "retrofitting" algorithm that produces a quasi continuous time BG profile by simultaneously exploiting the high accuracy of available BG references (possibly very sparsely collected) and the high temporal resolution of CGM data (usually noisy and affected by significant bias). The inputs of the algorithm are: a CGM time series; some reference BG measurements; a model of blood to interstitial glucose kinetics; and a model of the deterioration in time of sensor accuracy, together with (if available) a priori information (e.g. probabilistic distribution) on the parameters of the model. The algorithm first checks for the presence of possible artifacts or outliers on both CGM datastream and BG references, and then rescales the CGM time series by exploiting a retrospective calibration approach based on a regularized deconvolution method subject to the constraint of returning a profile laying within the confidence interval of the reference BG measurements. As output, the retrofitting algor

Apparatus, methods and computer programs for detecting critical events

Resumen de: GB2638147A

A system 100 comprises a number of devices 102 in communication with one another. The devices 102 are associated with a user 104 and may comprise a smartphone 102A, wearable devices such as a headset 102B or heart rate monitor 102C, and other local devices 102D,102E such as smart speakers including a microphone, cameras, motion sensors or other devices used for monitoring the area around the user 104. The wearable devices may comprise sensors for monitoring physiological parameters or an IMU for monitoring position or movement of the user 104. One or more of the devices 102 can be configured to detect a critical event. A critical event is an event considered to be dangerous or causes the user to require assistance such as cardiac events, a drop in blood sugar level, or a fall. If a critical event occurs, one or more of the devices 102 can raise an alarm or contact assistance. Before such takes place, the system confirms that a prospective critical event is an actual critical event by obtaining additional data from another device 102 in the system. This can help to avoid false alarms or other calls for assistance being raised unnecessarily.

COMPOSITIONS FOR GLUCOSE-RESPONSIVE DRUG DELIVERY SYSTEMS VIA MULTIFUNCTIONAL HYDROGEL-BASED MICRONEEDLE

Resumen de: WO2024077402A1

The present disclosure provides a matrix microneedle patch made of a hyaluronic acid (HA) polymeric backbone functionalized with dopamine (DA) and 4-amino-3-fluorophenylboronic acid (AFBA, pKa ~7.5) that quickly and spontaneously crosslinks upon mixing of the polymer solutions by auto-oxidation of catechol groups and reversible interactions between AFBA and catechol functional groups in the absence of any chemical crosslinking agent. The DA and AFBA content were selected for conjugation into the backbone of the HA polymer for the desired hormone delivery profile. The patch provides high drug loading capacity for long-term drug delivery application. The crosslinking mechanism for microneedle fabrication is biocompatible and beneficial for sustaining hormone drug stability and bioactivity as it does not require harsh crosslinking conditions. Facile pH adjustment of the matrix hydrogel can be easily casted into a microneedle patch without multistep processes that conventional patch polymerization requires. The present matrix microneedle patch demonstrates sufficient skin penetration, rapid swelling in interstitial media, high drug loading capacity and effective hypo/hyperglycemia prevention by the automated hypo/hyperglycemia-triggered delivery of hormones through the skin.

CONTINUOUS ANALYTE MONITOR DATA RECORDING DEVICE OPERABLE IN A BLINDED MODE

Resumen de: EP4601218A2

A system is provided for monitoring analyte in a host, including a continuous analyte sensor that produces a data stream indicative of a host's analyte concentration and a device that receives and records data from the data stream from the continuous analyte sensor.

Data received from the continuous analyte sensor may also be used to prompt the diabetic or caregiver to take certain actions, such as to perform another single point blood glucose measurement. In another embodiment, the device provides for toggling between two modes, with one mode that allows for display of glucose concentration values associated with the continuous glucose sensor and a second mode that prevents the display of glucose concentration values associated with the continuous glucose sensor.

INFUSION DEVICES AND RELATED RESCUE DETECTION METHODS

Resumen de: EP4599864A2

Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of operating an infusion device (100, 500) to deliver fluid to a body of a user involves obtaining measurement values for a physiological condition influenced by the fluid, autonomously operating the infusion device to deliver the fluid based at least in part on the measurement values, and detecting a nonactionable condition based on the measurement values. In response to detecting the nonactionable condition, delivery of the fluid is limited while maintaining autonomous operation of the infusion device. In one exemplary embodiment, the nonactionable condition is a rescue condition indicative of the user having consumed fast-acting carbohydrates, and thus insulin delivery may be automatically limited in response to detecting the rescue carbohydrate consumption.
