Some embodiments are directed to an adherence monitor for use with a tethered cap inhaler device. The adherence monitor engages the inhaler device, and includes a tether opening located within a housing of the adherence monitor for receiving the tether. The tether opening is in the form of a slot in a base portion of the housing. The path length of the tether around the adherence monitor is kept from being increased, compared to its path length when the adherence monitor is not attached to the inhaler, by having the slot located to allow the tether to pass through the slot. Various sensors of the adherence monitor in various embodiments detect inhaler usage.

A system for mass vaccination includes a plurality of portable electronic injectors, a mobile process manager and a database. Each portable electronic injector includes at least one needle to administer a measured amount of at least one vaccine to a body skin/tissue and an indicator system to provide an indication when either an injection error occurs or when a vaccination indication is required. The mobile process manager is in wireless communication with the plurality of injection devices and controls a mass vaccination. The process manager transmits task data to all injection devices in parallel via WI-FI, receives the vaccination indications from each injector in real time, also receives injection errors and vaccination process data, alerts a vaccination process overseer generally in real-time of the errors and transmits the injection data from each injector via cellular and/or internet transmission to the database.

A chemical-liquid injection head including a syringe holding unit which holds a syringe in which a piston member is slidably inserted into a cylinder member having a circular cylindrical shape, a piston driving mechanism having a ram member for moving the piston member of the syringe, and a first light emitting portion which emits light with a first color and illuminates the syringe and a second light emitting portion which emits light with a second color and illuminates the syringe. The first light emitting portion and the second light emitting portion, viewed in a posture at the time of use of the injection head, are provided at an upper side of the ram member.

A catheter system may include a catheter lumen, first and second electrodes, and a sensor in communication with the first and second electrodes. The sensor may be configured to detect at least one of: a bulk volume of blood within a blood vessel and extravasation of a drug from the blood vessel into soft tissue adjacent the blood vessel. Other catheter systems may include a catheter lumen and a sensing chip coupled to the catheter lumen. The sensing chip may be configured to detect at least one of: a bulk volume of blood within a blood vessel and extravasation of a drug from the blood vessel into soft tissue adjacent the blood vessel.

A feedback providing facial mask is provided. The mask includes a facial adaptive component including a deformable member embedded in an interior region of the facial adaptive component and circuits, each of the circuits being operable in an open-circuit state or a closed-circuit state. The mask also includes a battery, light elements coupled to the battery and positioned within the deformable member, and sensors positioned at a plurality of locations within the deformable member. The sensors are connected to one of the light elements, wherein each of the circuits include the battery, one of the light elements, and at least one of the plurality of sensors, and wherein one or more of the circuits change from operating in the open-circuit state to the closed-circuit state in response o the one or more of the sensors contacting skin on an object that is external to the mask.

Disclosed cannula systems can detect the tissue type within which the cannula tip is located in real time using electrodes adjacent the cannula tip. The sensing cannula system can differentiate when the cannula tip is in adipose tissue or muscle based on electrical impedance. The system can be used in fat grafting and liposuction procedures, for example. An operator can detect if the cannula tip enters muscle by watching for an indicator light or audible alarm that is automatically activated by the device based on a change in sensed impedance. The device may also stop the flow of fat through a pump halting injection into the sub-muscular space.

Methods and systems are provided for assisting a user of a wearable biosignal monitoring device (2) in adjusting the device to achieve optimum fit and positioning. The biosignal monitoring devices considered use integrated bio sensors (5) to monitor the user’s physiological activity for various purposes such as tracking daily activity patterns, determining mood, and monitoring sleep stages, among others. It is determined either during device setup or during primary use of the device whether the current fit and positioning of the device (2) enable the bio sensors (5) to properly sense the physiological signals needed for the device to perform its primary function. The user is then informed either after initial device setup whether adjustments need to be made in order to optimize device function during primary use, or is informed after primary use whether adjustments need to be made in order to improve device function during future primary use.

A main unit connected to a vaporizer and controlling operation of the vaporizer includes: a processor; and a battery, a timer, and a memory that are connected to the processor. The processor controls the battery to provide energy for the vaporizer to allow the vaporizer to vaporize an aerosol-generating substrate. The processor calculates an accumulative temperature during vaporization of the vaporizer based on timing information of the timer and a vaporization temperature change curve stored in the memory.
