Brush portions are configured for use with a handheld device. The brush portion includes at least one bristle disposed on a bristle base, the bristle having an elongate first electrode, an elongate second electrode abutting the first electrode, and an insulator disposed between the first electrode and the second electrode. The first electrode and the second electrode are electrically connectable to a first voltage source and a second voltage source of the device, respectively.

A diagnostic tool can include a face mask, a casing, a plurality of sensors, and processing circuitry. The face mask can include an air-intake port, a first check valve integrated into the air-intake port, an air-exhaust port, and a second check valve integrated into the air-exhaust port. The casing can be coupled to the face mask having an air-intake chamber coupled to the air-intake port and an air-exhaust chamber coupled to the air-exhaust port. The processing circuitry can be communicatively coupled to the plurality of sensors. The processing circuitry can include computing logic for handling information detected by the plurality of sensors.

An insertion mechanism for a drug pump includes an insertion mechanism housing; a sleeve; a rotational biasing member initially held in an energized state; a retraction biasing member and a hub connected to a proximal end of a needle, wherein the retraction biasing member is held initially in an energized state between the hub and the sleeve. The needle is inserted into a target tissue by the rotational biasing member and interaction between the hub and housing. Retraction of the needle is caused by decompressing or de-energizing of the retraction biasing member. A drug delivery pump includes an activation mechanism, a drive mechanism, a sterile access connection, and the insertion mechanism. Assembly and operation methods are provided.

The invention relates to a needle delivery device comprising a device body; one or more skin pinching members attached to the device body, the skin pinching members being moveable to pinch a longitudinal fold of skin of a patient. The device also comprises a drive mechanism configured to drive a needle out of the device body and along a needle path into the longitudinal fold of skin pinched between the pinching members, and subsequently withdraw the needle, the needle path extending substantially parallel to the surface of the patient.

A medical infusion fluid handling system, such as an automated peritoneal dialysis system, may be arranged to de-cap and connect one or more lines (such as solution lines) with one or more spikes or other connection ports on a fluid handling cassette. This feature may reduce a likelihood of contamination since no human interaction is required to de-cap and connect the one or more lines and the one or more spikes. For example, the automated peritoneal dialysis system may include a carriage arranged to receive the one or more lines each having a connector end and a cap. The carriage may move along a first direction so as to move the connector ends of the one or more lines along the first direction, and a cap stripper may be arranged to engage with the caps on the one or more lines on the carriage. The cap stripper may move in a second direction transverse to the first direction, as well as to move with the carriage along the first direction.

System and method for identification and verification of authorization of a subject to use a substance delivery device.

The present disclosure relates to charging accessory device for the aerosol delivery device and related systems, methods, apparatuses, and computer program products for providing interactive services for aerosol delivery devices. For example, a method may include a computing device establishing communication with a charging accessory device for an aerosol delivery device; receiving usage data for the aerosol delivery device provided by the charging accessory device; generating social data based on the usage data; and sending the social data to a social networking service including a community of aerosol delivery device users.

A hydrogen supply apparatus includes: an air path having an inlet and an outlet; a fan that is disposed in the air path and produces a flow of air from the inlet to the outlet; a first pipe having an end that forms a first supply port through which to supply hydrogen gas to the air path; a flow control device that is attached to the first pipe and adjusts a flow rate of the hydrogen gas; and a hydrogen gas sensor, disposed downstream of the fan or the end in a direction of flow of the air that detects a concentration of the hydrogen gas in the air path, where the end is disposed between the fan and the outlet or between the fan and the inlet in the air path.

A drug delivery device includes an injector and an accessory grip. The injector includes an injector housing defining a housing body having a proximal end, a distal end, and a longitudinal axis extending therebetween, a needle assembly at least partially disposed within the injector housing at the proximal end, and a drive assembly at least partially disposed within the housing. The needle assembly includes a syringe barrel containing a medicament and a needle or a cannula. The drive assembly urges the medicament through the needle or cannula. The accessory grip defines a grip shell having proximal and distal ends, and a body extending therebetween. The proximal end includes a first opening dimensioned to receive a first portion of the injector housing, and the distal end of the grip shell includes a second opening that receives a second opening dimensioned to receive a second portion of the injector housing.

A portable insulin pump can utilize readings from a sensor incorporated into an infusion set used with the pump to deliver insulin to a patient to determine if the infusion set is or is likely to become dislodged from the patient. Readings from the sensor that are inconsistent with expected readings or a range of expected readings can indicate that the infusion set has become dislodged from the patient.
