Disclosed herein is an auto injector for administering a medicament, the auto injector comprising: a housing; a cartridge receiver configured to receive a cartridge comprising a first stopper and a cartridge compartment containing the medicament, the cartridge compartment having a first cartridge subcompartment containing a first medicament component of the medicament and a second cartridge subcompartment containing a second medicament component of the medicament; a drive module coupled to move a plunger rod between a retracted plunger rod position and an extended plunger rod position, the plunger rod being configured to move the first stopper; a processing unit coupled to the drive module, wherein the processing unit is configured to control the drive module to move the plunger rod from a first plunger rod position to a mix plunger rod position with a mix plunger rod speed, wherein the mix plunger rod position is selected to position the first stopper in a position wherein the first medicament component is mixed with the second medicament component, and to provide an onset signal after a number of completed inversions of the auto injector has been performed.

An inhalation device uses a base substance to generate aerosol to be inhaled by a user. The inhalation device includes a storage unit that stores information, a communication unit that receives information from another device when a first condition is satisfied, and a control unit that causes the storage unit to store the information received from the other device when a second condition is satisfied.

A handheld personal communication apparatus for dialysis includes a reader to read a marking displayed on a dialysis fluid container to acquire data concerning at least one of a dialysis fluid type or a dialysis fluid volume from the marking; a processor using the at least one of the dialysis fluid type or the dialysis fluid volume to determine a dialysis dwell time for at least one cycle of a dialysis therapy, the dialysis dwell time being a time to achieve, over the at least one cycle, at least one of (a) a specified ultrafiltrate level, (b) a urea removal level, or (c) a creatinine removal level; and an output interface providing an indication to the patient of a completion of the dialysis dwell time.

A sensor device is removably attachable to a drug delivery device. The sensor device comprises an array of optical sensors arranged within the sensor device such that, when the sensor device is attached to the drug delivery device, which has a first movable element configured to move along a path parallel to the longitudinal axis of the drug delivery device, each optical sensor is operable to detect light received at different locations along the path and to output a signal indicative of an amount of detected light. Circuitry is configured to receive the signals output from the optical sensors and, based on the received signals, determine information associated with a location along the path of the first movable element.

Systems and methods for nitric oxide generation are provided. In an embodiment, an NO generation system can include a controller and disposable cartridge that can provide nitric oxide to two different treatments simultaneously. The disposable cartridge has multiple purposes including preparing incoming gases for exposure to the NO generation process, scrubbing exhaust gases for unwanted materials, characterizing the patient inspiratory flow, and removing moisture from sample gases collected. Plasma generation can be done within the cartridge or within the controller. The system has the capability of calibrating NO and NO.sub.2 gas analysis sensors without the use of a calibration gas.

Systems and methods for nitric oxide (NO) generation systems are provided. In some embodiments, an NO generation system comprises at least one pair of electrodes configured to generate a product gas containing NO from a flow of a reactant gas. The electrodes have elongated surfaces such that a plasma produced is carried by the flow of the reactant gas and glides along the elongated surfaces from a first end towards a second end of the electrode pair. A controller is configured to regulate the amount of NO in the product gas by the at least one pair of electrodes using one or more parameters as an input to the controller. The one or more parameters include information from a plurality of sensors configured to collect information relating to at least one of the reactant gas, the product gas, and a medical gas into which the product gas flows.

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.

A nasal droplet delivery device and related methods for delivering precise and repeatable dosages to a subject via the nasal passageways and sinus cavities.

An electronic system for a drug delivery device is provided. The electronic system comprises a dose setting and drive mechanism comprising a first member and a second member, wherein in the dose delivery operation and/or in the dose setting operation, the first member moves, e.g. rotates, relative to the second member; an electronic control unit; an electrical use detection unit operatively connected to the electronic control unit, and configured to generate a use signal in response to the relative movement, e.g. a relative rotational movement, between the first member and the second member, preferably during the dose delivery operation. The electronic system is configured such that it is switched from a first state into a second state by the electronic control unit in response to the use signal, wherein the electronic system has an increased electrical power consumption in the second state as compared to the first state.

A system and method for tracking and administering liquid intravenous medications in a hospital, clinic, or patient residence, including recording information onto a short range communication device affixed to a liquid container in a hospital pharmaceutical filling or compounding center, the information including drug information, patient information, and IV administration information, transferring the liquid container to a patient's bedside, programming an infusion course into a bedside IV infusion pump by enabling the pump to read the encoded information on the communication device, and disposing of the liquid container and any residual drug in a smart disposal bin that reads the communication device and weighs the container. The disposal bin may confirm the chemical contents of the container.
