A method of controlling a medical fluid therapy machine display brightness includes: performing a medical fluid therapy using the medical fluid therapy machine, the medical fluid therapy machine including a display; sensing an amount of ambient light impinging the display without receiving light directly from the display; controlling a level of backlight brightness for the display based on the amount of ambient light sensed; and displaying information relating to the medical fluid therapy on the display using the controlled level of backlight brightness.

A multi-chamber injection device includes multiple syringes. The multiple syringes may be arrayed in a circular, linear, or other format. In some implementations, a needle, port, or similar may be shared by all the syringes in configuration that allows only one syringe to deliver contents at a time while blocking the other syringes from delivering their respective contents. In some implementations, the syringes may be all stored in the same container. One or more of the chambers of a multi-chamber injection device may be preloaded with medication. Different medications may be loaded into different chambers. The medications may be selected to treat the same medical condition.

A holder with a safety shield for a drug delivery device; the shield obstructing access to a needle of the drug delivery device following use thereof. The safety shield may be actively deployed, in which case the health care worker must perform an action beyond complete depression of the pusher into the body of the drug delivery device to deploy the shield. Alternatively, the safety shield may be deployed passively or automatically, in which case deployment of the shield occurs upon complete depression of the pusher into the body, with no additional action required of the health care worker. The safety shield is spring-loaded and released to its extended position by a mechanical coupling of a series of position members, including levers, formed on the holder and the drug delivery device.

Provided is a pressure gauge capable of being effectively used for internal pressure measurement of a balloon catheter and capable of providing easy monitoring of a pressure value even when measuring internal pressure of an extracorporeal circulation circuit. The pressure gauge measures internal pressure of a balloon catheter used for treatment and diagnosis or pressure of a body lumen of a living body and includes a coil-shaped tube 2 to elastically deform. One end of the tube 2 is set as an open fixed end and the other end is set as a sealed free end and pressure introduced from the open fixed end can be measured based on a displacement position of the tube 2 due to the pressure.

There is provided in accordance with an exemplary embodiment of the invention, a device and a method for controlled extraction of at least one active substance from at least one type of plant matter by application of heat, the device comprising: a heating element adapted to apply heat to an area of the plant matter to extract the substance; and a mechanism adapted for moving the plant matter relative to the heating element. Optionally, the active substance is a restricted substance. There is also provided in accordance with an exemplary embodiment of the invention, a method of monitoring and controlling inhalation of a restricted substance. There is provided in accordance with an exemplary embodiment of the invention, a method of manufacturing a tape of plant matter comprising an active substance.

A sensor device removably attachable to a drug delivery device includes a sensing arrangement arranged within the sensor device and circuitry configured to process signals provided by the sensing arrangement. The sensing arrangement is configured such that, when the sensor device is attached to the drug delivery device, the sensing arrangement is operable to read encoded information present on a rotatable component internal to the drug delivery device and that is able to be sensed through a window or aperture of the drug delivery device, and is operable to sense through the window or aperture at least a part of a drive mechanism of the drug delivery device. The circuitry is configured to determine information relating to a set dose, and to determine information relating to whether the drug delivery device is in a dose setting mode or whether the device is in a dose delivery mode.

[Problem] To accurately check a usage status of a medical product such as a damage status of the medical product or existence or nonexistence of the medical product.

[Solution] A medical product (80) is configured to include a light-emissive septum (83) (constituent member) which includes a luminescent agent emitting near-infrared fluorescence according to irradiation of excitation light on a surface thereof. Even in a case where a portion of the septum is separated as a core (83a) (separate piece) due to damage, the luminescent agent is also included on a surface of the core. A medical product usage status checking apparatus (10) is configured to include a medical product which emits the near-infrared fluorescence, an irradiation unit (130) which irradiates the medical product with excitation light which excites the luminescent agent, an optical filter (140) which blocks the excitation light and transmits the near-infrared fluorescence emitted by the luminescent agent, a camera (15) (imaging unit) which receives the near-infrared fluorescence passing through the optical filter, and a monitor (160) (display unit) which displays an image captured by the camera. An image based on the near-infrared fluorescence of the septum is displayed on the monitor and in a case where damage occurs in the septum, an image based on the near-infrared fluorescence of the core is displayed on the monitor.

An apparatus includes a first tray member, a second tray member, and a lid. The first tray member has a first portion and a second portion. The first portion defines a first volume, and the second portion defines a second volume configured to receive a medicament container. The second tray member defines a third volume having a sidewall including a retention portion configured to retain an ocular injector within the third volume. The second tray member is coupled within first volume such that the sidewall of the second tray member and a sidewall of the first tray member enclose the ocular injector. The lid is coupled to the first tray member about the first volume, and is constructed from a material formulated to maintain sterility of the first volume.

A communication device arranged for transmitting information from a medicament delivery device is presented. The communication device includes at least one rotation detection arrangement, the at least one rotation detection arrangement being configured to detect a rotation of at least one physical part of the medicament delivery device. The communication device also includes at least one determination unit configured to determine information related to a medicament delivery performed by the medicament delivery device. The communication device further includes at least one activation unit configured to activate the at least one determination unit based on the detected rotation. Also, the communication device includes at least one transmission unit configured to provide a wireless transmission of the information to an external receiving device.

Disclosed is an auto injector and a method for administering a medicament. The auto injector comprising: a housing; a cartridge receiver; a drive module coupled to move a plunger rod configured to move a first stopper; a temperature sensor configured to provide a temperature signal indicative of the temperature of the medicament in the cartridge; a processing unit configured to: receive the temperature signal; control the drive module to move the plunger rod from a first plunger rod position to a mix plunger rod position wherein the movement from the first plunger rod position to the mix plunger rod position is based on the temperature signal.
