Embodiments of the present disclosure enable a user-wearable infusion pump that may have a limited user interface including no display to be paired with a remote control device that can include a remote consumer electronic device such as a smartphone and/or a dedicated remote controller.

A personal respiratory isolation system (PRIS) provides a personal, negative pressure environment for a patient or user that reduces contamination and spread of pathogens exhaled by the patient into the environment. The PRIS includes an enclosure to receive the patient's head (such as a hood and a drape) and a negative pressure source which draws ambient air into the interior of the enclosure and draws air within the enclosure's interior (including the exhalations of the patient, including any contaminants and/or pathogens) out of the enclosure via a fluid port into a container for biohazard processing or disposal. The PRIS may allow positive air pressure therapeutic treatments to be delivered to the patient within the negative pressure environment, and the PRIS may maintain a constant pressure within the interior of the enclosure. The PRIS may include a transparent, hinged face shield for ease of patient observation and/or access.

There is provided a method for controlling the movement of bile and/or gall stones in the biliary duct. The method comprises gently constricting (i.e., without substantially hampering the blood circulation in the tissue wall) at least one portion of the tissue wall to influence the movement of bile and/or gallstones in the biliary duct, and stimulating the constricted wall portion to cause contraction of the wall portion to further influence the movement of bile and/or gallstones in the biliary duct. The method can be used for restricting or stopping the movement of bile and/or gallstones in the biliary duct, or for actively moving the fluid in the biliary duct, with a low risk of injuring the biliary duct.

Implementations of the present disclosure are directed to an injection device (102) including a medicament reservoir (103) configured to store a medicament to be expelled by the injection device (102), an acoustic source (122a, 122b, 122c, 122d, 200, 300, 400) configured to generate an acoustic signal including information indicative of an amount of the medicament stored in the medicament reservoir (103), the acoustic signal being transmitted to an external device (104) configured to process the acoustic signal and to extract injection device data.

An insulin delivery and data collection system includes at least one insulin delivery device, a holding station, and control system. The holding station includes a body defining at least one cavity extending into the body from an upper surface of the body, the at least one cavity configured to receive the at least one insulin delivery device and at least one load cell disposed at a bottom of the at least one cavity. The control system includes at least one processor and at least one non-transitory computer-readable storage medium storing instructions thereon that, when executed by the at least one processor, cause the control system to receive weight data from the at least one load cell related to the at least one insulin delivery device.

Introduced here are systems for facilitating wireless power transfer to devices that are implanted in living bodies. The wireless power systems described herein utilize inductive coupling between a pair of resonators—namely, a first resonator located external to a living body and a second resonator located internal to the living body—for efficient wireless power transmission. Each resonator can include a conductive loop with at least one interruption in which discrete capacitors are situated. Moreover, each resonator may include a magnetic core that shapes the magnetic field created by the corresponding conductive loop.

A Direct Sodium Removal method, apparatus and solution for treating patients in heart failure, and having a glomerular filtration rate greater than 15 mL/min/1.73 m.sup.2, or residual kidney function corresponding to normal to CKD Stage 4, is provided in which a no or low sodium DSR infusate is administered to the peritoneal cavity for a predetermined dwell period and then removed, thereby removing sodium from the body. The resulting elimination of fluid from the patient by i) functioning of the kidneys through urination and ii) direct removal of osmotic ultrafiltrate from the peritoneal cavity, restores serum sodium concentrations to healthy levels and thereby reduces fluid overload in the patient.

A power supply unit for an aerosol inhaler includes: a case; a power supply that discharges power to a load for generating an aerosol from an aerosol generation source; a discharging terminal that connects the load to the power supply; a charging terminal that connects the power supply to an external power supply and is separated from the discharging terminal; a temperature measuring unit that measures temperature of the power supply; and a control device that controls an effective value of a first charging current to a value smaller than an effective value of a second charging current. The first charging current is supplied to the power supply when a measurement value of the temperature measuring unit is equal to or higher than a first threshold and the second charging current is supplied to the power supply when the measurement value is lower than the first threshold.

The present disclosure relates to a drug administration device configured to administer a drug. In an exemplary embodiment the drug administration device includes a housing including first and second housing electrical contacts, a dispensing mechanism, a drug holder, a removable power supply including first and second power supply electrical contacts, and at least one protection mechanism in a first protecting configuration when the removable power supply is not received within the housing and in a second configuration when the removable power supply is received within the housing. In another exemplary embodiment the drug administration device includes a housing, a dispensing mechanism disposed within the housing, a removable power supply that is configured to be received within the housing, a sensor configured to determine remaining charge of the removable power supply, and a processor configured to modify operation of the drug administration device in response to data produced by the sensor.

The operational parameters of a respiratory apparatus can be controlled through the use of a user interface located on a separate or separable mobile computing device. Sensors or features located on the mobile computing apparatus can be used to adjust the operation parameters or therapy of the respiratory apparatus or otherwise improve the compliance of a patient utilizing the respiratory apparatus.
