The invention relates to administration systems and to methods which can improve the safety of administration systems, more particularly the safety of an infusion system, in which system it is checked, when the medication container is exchanged, whether the new container is appropriate for the system. A system of this type consists of an administration device (1), a mobile communication device (3) and servers (5). When a reservoir (2) or the administration device (1) is replaced, an image of information (2a) is captured by means of a camera (3a) of the communication device (3). As a result of evaluation of the information (2a) by means of a software application, functions of the administration device (1) are activated or not.

A system for confirming acquisition of a fluid sample is provided. The system includes a wearable electronic device configured to be worn by a user. The device has a housing, at least one imaging sensor associated with the housing, a data transmission interface for sending data to or receiving data from an external electronic device, a microprocessor for managing the at least one imaging sensor and the data transmission interface, and a program for acquiring and processing images acquired by the at least one imaging sensor. The system further includes a sampling device for collecting a fluid sample in a sample container and at least one identification tag attached to or integrally formed with the sampling device or sample container. The at least one identification tag includes or is associated with a tracking code.

A drug delivery device system with mutable indicia and method for using same are provided. The drug delivery device system includes a syringe and/or syringe components (e.g., needle shield, needle guard), or autoinjector pen, or wearable autoinjector with mutable indicia and a software application for an external device to analyze images of the mutable indicia to automatically determine and record status of the drug delivery device. The mutable indicia or codes on the drug delivery device or its components represent different medical events such as dose completion, dose amount, and safety feature deployment or removal and can be detected by and otherwise logged by the external device. The external device may execute an application configured to further process data obtained via captured images of mutable indicia and display related information (e.g., fluid remaining in syringe barrel, delivered dose, and so on).

A chemical-liquid injector includes a piston-driving mechanism (130) that moves a piston member of a syringe containing a contrast medium, which includes an actuator and a ram member which is moved back and forth by the actuator, a control circuit (150) which is electrically connected to the actuator, and an operating knob unit (170) which includes an operating knob that is to be operated by an operator, and a rotation sensor that outputs an electric signal corresponding to a rotation of the operating knob. The control circuit is configured to generate a predetermined control signal accordingly, on the basis of a signal from the rotation sensor, and the piston-driving mechanism is operated according to the control signal.

A method and apparatus for a connection interface between a reservoir or syringe, infusion set tubing, and an infusion pump is provided. The reservoir, a base and a cap are connected to form an integrated unit that is capable of being inserted and secured in an infusion pump housing. The cap and the infusion pump are each provided with at least one sensor or at least one detectable feature, arranged to interact with at least one corresponding detectable feature or sensor on the other of the cap and infusion pump device, to detect one or more of the presence, position or other characteristic of the cap when the cap is aligned or coupled with the infusion pump housing. The detectable feature and sensor may be magnetic, RF, mechanical, optical or any combination.

A method of tracking injections includes depressing a plunger of a medication injection device, and sending and receiving ultrasonic signals from a plunger head installed within a barrel of the medical injection device. The method also includes measuring a time of flight for the signals to travel through the medication, and determining a position of the plunger head based on the time of flight of the signals. Additionally, a plurality of data samples representative of the position of the plunger are logged, and a distance the plunger head travels is calculated. This is used to calculate the quantity of the medication dispensed based on the distance the plunger head travels. An external device is then used to back-interpolate a time corresponding to each data sample logged in order to determine the time the quantity of medication was dispensed.

A drug delivery device monitoring system is provided. The system includes a drug delivery device having a visually-identifiable feature reflecting a state or an indicia of the drug delivery device; an electronic recordation device configured to capture an image of the visually-identifiable feature and generate image data therefrom; and a computing system operable to perform image analysis on the image data to generate interpreted data therefrom. The interpreted data is provided to a stakeholder monitoring the drug delivery device.

Apparatus comprising: a sensor configured to generate sensor output dependent on an intensity of light incident on the sensor and having a field of view directed at an external surface in use; an illumination source configured to emit light onto the external surface in use; a window located such as to allow light to pass from the illumination source to the external surface and to allow light to pass to the sensor from the external surface in use; a shield coupled to or integral with the window, the shield being substantially opaque to substantially all wavelengths of light detectable by the sensor and defining an aperture which limits the field of view of the sensor; and a processor configured to use the sensor output to determine information associated with reflection characteristics of the external surface.
