A drive mechanism includes a housing, a piston adapted to impart movement to a plunger seal within a drug container, a plurality of biasing members disposed in parallel, and a retainer. The biasing members are disposed to release energy to cause movement of the piston from a retracted first position to the extended second position, the piston bearing against the plunger seal to dispense medicine. The retainer is disposed to maintain the biasing members in the energized position and to release the biasing members to permit the piston to dispense the medicine. The drive mechanism may also include an end-of-dose indicator to identify at least one of when the sleeve assembly is disposed subjacent a window in the housing, the relative motion of the sleeve assembly with reference to the window or another reference component, the stoppage of such motion, and the rated or change of rate of motion.

Method and apparatus for providing an integrated analyte sensor and data processing unit assembly is provided.

The present disclosure provides in part improved apparatuses, systems, and methods for providing therapy to a wound. A system can include a first power source configured to power an electronic component and a second power source configured to power the electronic component in place of the first power source. Responsive to a first condition, the second power source can power the electronic component in place of the first power source. In some cases, the system can include a pressure source that is configured to provide negative pressure to a wound dressing positioned over a wound. The wound dressing can support the first power source or the second power source.

The present disclosure illustrates a sensor-controlled nasal aspirator including a distance sensing unit, a micro processing unit and an air pump. The distance sensing unit is configured to sense a distance between a target object and the distance sensing unit. The micro processing unit is configured to store a preset distance, and receive and process the distance transmitted from the distance sensing unit, and transmit an action command signal when the distance is not higher than the preset distance. The air pump is configured to receive the action command signal and performs a target action according to the action command signal.

The present disclosure relates to a transportable device for providing a cooled, oxygen-containing gas flow for supplying to a body of mammal via the respiratory tract, in particular a human being, in order to lower the body temperature. The device comprises a storage device comprising at least one fluid reservoir and at least one heat exchanger, wherein the storage device is designed to store an oxygen-containing fluid in the fluid reservoir and for providing a discharge flow of the oxygen-containing fluid. The heat exchanger is designed to cool the provided discharge flow by transferring heat to a cooling stream of a stored fluid and provided by the storage device, and a cooled, oxygen-containing gas flow for supplying to the body emerges from the heat exchanger.

A drug delivery device includes a housing, a drug delivery assembly disposed within the housing along a longitudinal axis, and a cap defining a shell. At least one electronic component, a power source, and a switch assembly are at least partially disposed in and coupled to the cap. The switch assembly is movable along a plane orthogonal to the longitudinal axis of the drug delivery assembly to cause the power source to provide power to the electronic component. The device further includes an activation mechanism at least partially disposed in the cap. Upon urging the cap along the longitudinal axis in a direction away from the housing, the activation mechanism engages the switch assembly and causes the switch assembly to move, thereby causing the power source to provide power to the at least one electronic component.

Disclosed herein is a molecular imprinted protective face mask comprising a supportive structure, a surface material that receives and retains a molecular imprint and that is positioned to contact airborne molecules during use, a molecular imprint of a bioactive molecule wherein an imprinted cavity is at least one of a bioactive molecule with a molecular configuration that captures a specific airborne and/or microdroplet-borne molecule and a protein with a binding site that captures a specific molecule.

An apparatus such as a fluid mixer, suitable for use with a respirator, including a venturi nozzle for flow of a pressure-controlled fluid; an ambient fluid aperture in fluid communication with the venturi nozzle; a fluid port; a pressure force multiplier in fluid communication with the fluid port; and a valve moveable relative to the venturi nozzle between a start flow position and a stop flow position; where the pressure force multiplier is configured such that fluid forced into the fluid port actuates the valve relative to the venturi nozzle; and where the pressure force multiplier is configured such that fluid withdrawn from the fluid port actuates the valve relative to the venturi nozzle. A method of using an apparatus suitable for a ventilator is also disclosed.

The present invention relates to a motor-driven suction pump and a method for connecting such a pump. The suction pump has a pump unit for generating a negative pressure which is accommodated in a housing. Further, a terminal box is provided which can be connected to a power source via a connecting cable and has contact elements for supplying the pump unit with a power current. The contact elements are electrically conductively connected to the contact counter elements provided on the housing side and leading to the pump unit when the terminal box is coupled to the housing. In order to increase electrical safety, a sensor, an evaluation unit, and a switch are provided. The sensor is configured to check the coupling of the terminal box. The switch switches a power supply to at least one of the contact elements. The evaluation unit is data-based connected to the sensor and the switch such that the switch connects the contact element to the power current supply when a signal of the sensor confirming the coupling is present and disconnects the power current supply when a signal of the sensor confirming the coupling is absent. In the method according to the invention, at least one contact element which is switched off is first electrically connected to the counter contact element on the housing side, which is provided for supplying current to the pump unit. The power current is then applied to the contact element on the basis of a signal confirming the corresponding contacting.
