  • Patent number: 9707338
    Abstract: An ambulatory infusion device includes a common module having a pump mechanism and a fluid flow path in communication with the pump mechanism. The device also includes a custom module operably coupleable to the common module. The custom module includes a reservoir for housing a liquid composition comprising a medicament and control electronics. The reservoir is configured to fluidly couple with the fluid flow path, and the control electronics are configured to electrically couple to the pump mechanism when the common module and the custom module are operably coupled. When the common module and the custom module are operably coupled, the pump mechanism is configured to drive the liquid composition from the reservoir to a patient via the fluid flow path, and the control electronics are configured to control the rate at which the pump mechanism drives the liquid composition.

  • Patent number: 9649442
    Abstract: The present invention is directed to an automatic reconstitution drug delivery device. The inventive device effects simple and automatic reconstitution of a dry drug. To effect reconstitution, a user displaces a release button which causes first and second chambers of a drug cartridge to communicate, resulting in automatic mixing of a diluent and dry drug to effect reconstitution of the dry drug. The user then simply sets the dose volume using a dose-setting mechanism, and administers the injection in a manner typical of self-injection drug delivery devices. Whole or partial automatic priming can be also achieved by the device.

All pending medication orders are displayed on the screen of the controller and any may be selected by the clinician. Selecting a pending order at the controller that involves an infusion to the patient also results in automatic programming of the infusion pump in accordance with that order. Selection of an oral medication at the controller results, as does selection of any other order, in notification to the healthcare facility server that the order is being administered. Such notification resolves open controlled item transactions as well as provides information that may be relevant to a patient's EMAR.

  • Patent number: 9155835
    Abstract: A medicament dispensing device capable of managing the effective use period of a medicament preparation-containing syringe by simply and accurately detecting a period of time after the start of use of the preparation. In a medicament dispensing device (1), when a medicament preparation-containing syringe (11) is replaced, a microprocessor (23) detects the time at which the replacement is performed as the time of the start of use of the preparation, and counts the elapsed time after the use of the preparation has started. Then, the microprocessor (23) notifies the result of the counting by a LCD (10), etc. to the user. Also, the microprocessor (23) detects that a syringe needle for dispensing the preparation has been mounted, and after detecting the mounting of the syringe needle, the microprocessor (23) counts the elapsed time after the start of use of the preparation. In a step S12, the microprocessor (23) checks whether or not the elapsed time counted by a timer (21) has exceeded a specified time.

    Abstract: An injection device (1) with an End-of-Content mechanism. The End-of-Content mechanism comprises a track (91) and a track follower each coupled directly or indirectly to the housing and the dose setting member (20). When setting a dose, the housing and the dose setting member is rotated relatively to each other thereby also rotating the track-follower in the track a distance corresponding to the size of the set dose. This relative rotation is summarized and stored in the position of the track follower in the track. The housing containing the mechanism is preferably equipped with a transparent (71) area through which a user can inspect the position of the track follower in the track and thereby get a visible warning when the drug reservoir in the injection device is about to be emptied.
