A drug delivery device comprising: a housing; a cylindrical member rotatably supported within the housing; and a plurality of sensors; wherein: the outer surface of the cylindrical member is provided with a single track, the track forming an encoder and having a plurality of first track segments and a plurality of second track segments arranged along the length of the track which are respectively capable of inducing first and second responses in the sensors; and in each rotational position of the cylindrical member relative to the housing at least one different first track segment is capable of inducing a first response in at least one said sensor, thereby enabling the rotational position of the cylindrical member relative to the housing to be determined.

An intubation system includes a measurement apparatus that measures physiological parameter of a subject by a measuring section, an intubation apparatus that includes an imaging section placed in a vicinity of a tip end portion of an inserting section to be inserted from a mouth of the subject toward a target site, an intubation displaying section that is disposed integrally with or separately from the intubation apparatus and is connected to the imaging section and the measuring section to display an in vivo image that is taken by the imaging section along with the physiological parameter that is measured by the measuring section, and an overall storage section that stores the in vivo image and physiological parameter that are displayed on the intubation displaying section, in an associated manner.

A sleep system can introduce outside stimulus such as simulated heartbeat and/or respiration to induce a response from the sleeper which can cause the sleeper's body to mimic or mate up with the delivered heartbeat and/or respiration sequence. Simulated heartbeat and/or respiration introduced to the person's sleeping environment can guide the person from an awake state to a sleeping state, help the person transition between sleep stages, help the person maintain one or more sleep stages for longer or shorter durations, and gently guide the person from an asleep state to an awake state. The simulated heartbeat and/or respiration can also improve the quality of sleep that the person experiences in a given sleep phase.

The present invention relates to a medicament delivery device comprising a housing, a biased medicament delivery member guard arranged movable in relation to the housing from a proximally extended position to a retracted position, a power pack comprising a plunger rod and a force element arranged to act on said plunger rod, which power pack is actuated by a release clip movable in relation to the housing and arranged to said plunger rod for releasably holding said plunger rod with the force element in a tensioned state; a rotator rotatably arranged inside said housing, which rotator is arranged with a guide element and a medicament delivery member guard lock element on its outer surface, wherein said medicament delivery member guard is arranged with release clip activation elements operably arranged to act on said release clip for releasing said plunger rod, and wherein said medicament delivery member guard is further arranged with a rotator activator element arranged to cooperate with said guide element for turning said rotator, upon movement of said medicament delivery member guard to the retracted position, and wherein, upon movement of said medicament delivery member guard back to the extended position, said rotator activator element will engage said medicament delivery member guard lock element and lock said medicament delivery member guard in a shielding position after removal of said medicament delivery device from a medicament delivery site.

Methods and apparatus to reduce deadspace in syringes and other devices with the use of volume displacing members that occupy space within one or more interior spaces of such devices. The volume displacing members are also equipped with one or more internal flow passages that facilitate a flow of a fluid through it. The volume displacing members are also adapted to cooperate with features of the devices that house them to form air-tight and liquid-tight seals that at least partially determine a fluid pathway through the devices.

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.

A gas collection unit for use in monitoring and tracking a discharge of air from a patient includes a housing, a set of valves, and a plurality of tubes. The housing contains a first chamber, a second chamber, and a third chamber wherein the chambers are in fluid communication with one another. The housing includes a fluid in the first chamber and the second chamber. The first valve regulates the passage of air flow from the patient into the first chamber and is located within a first tube coupled to the housing. The second valve is in communication with the second chamber. The second valve being configured to regulate the passage of air exiting the first chamber. The second chamber is subjected to a suction. The gas collection unit is operable with an air collection device as a retrofitted item.

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.

Disclosed is a method for controlling an auto injector and an auto injector for administering a medicament from a cartridge having a first cartridge end and a second cartridge end and having a cartridge outlet at the first cartridge end, the cartridge comprising a cartridge compartment with 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. The auto injector comprises: a housing; a cartridge receiver; a cartridge sensor; a drive module; an orientation sensor; and a processing unit.
