Infusion pump interfaces providing simple and intuitive user experiences. A controller display subsystem for implementing infusion pump interfaces includes a processor, a memory, display logic, keypad I/O, and screen I/O. Display logic can command the processor via the memory to implement desirable displays on screen I/O.

Implantable infusion devices and methods that provide closed loop control.

The present invention provides a device for regulating liquid medicine supply, wherein air that exists in a liquid medicine or between portions of a liquid medicine is removed in advance by an air removal filter provided on a discharge path in the device so that priming as a preparatory operation for injection of the liquid medicine into a patient can be accelerated and it is possible to reduce an unnecessary loss of the liquid medicine, which is caused by discharge of the liquid medicine for removal of the air existing in the liquid medicine or between portions of the liquid medicine. Further, the present invention provides a device for regulating liquid medicine supply, wherein air existing between portions of a liquid medicine, which may be produced by a difference in flow speeds of the portions of the liquid medicine flowing in the device, is removed by an air removal filter provided on a discharge path in the device so that an increment of the liquid medicine can be rapidly injected and a user can directly and conveniently regulate the injection amount of the liquid medicine as desired.

Disclosed are methods and medical device systems for automated delivery of therapies for pain and determination of need for and safety of treatment. In one embodiment, such a medical device system may comprise a sensor configured to sense at least one body signal from a patient; and a medical device configured to receive a first sensed body signal from the sensor; determine a patient pain index based at least in part on said first sensed body signal; determine whether said patient pain index is above at least a first pain index threshold; determine a safety index based at least in part on a second sensed body signal; select a pain treatment regimen based on at least one of said safety index and or a determination that said pain index is above said first pain index threshold; and deliver said pain treatment regimen.

A medical fluid injection device includes a pump, a communication part, a pump control part, and a storage part. The pump control part is configured to control the pump to start medical fluid injection when the communication part receives a start signal, and to stop the medical fluid injection when the communication part receives a stop signal, and the storage part is configured to store start inputter information together with start instruction information including information indicating that an instruction of starting the medical fluid injection is given, and stop inputter information together with stop instruction information including information indicating that an instruction of stopping the medical fluid injection is given.

A drug delivery and monitoring device comprising a nerve stimulating element configured to deliver an electric stimulus, a recording element configured to detect a compound action potential, and a drug-delivery element.

A fluid delivery device comprises a fluid reservoir for containing medicament. The fluid reservoir is sealed proximate one end with a sliding seal piston. A delivery path is configured to fluidly couple the fluid reservoir and a patient wearing the fluid delivery device. A basal engine mechanism is configured to directly or indirectly move the sliding seal piston in the fluid reservoir at a controlled basal rate. A bolus mechanism configured to move the basal engine relative to the fluid reservoir and directly or indirectly move the sliding seal piston in the fluid reservoir a discrete bolus amount at a time.

Systems and methods are provided for signaling a condition of an infusion assembly. A system may comprise an elastomeric pump that includes a chamber for receipt of a volume of fluid, an outer layer configured to expand and contract as the chamber receives and dispenses fluid, and a passive indicator provided on the outer layer for signaling a change in the volume of fluid in the chamber. The system further may comprise an image capture device configured to capture an image of the pump, and a processing system configured to process the image to signal the condition of the infusion assembly to a user of the system. A method may comprise capturing an image of a pump; processing the image; and displaying information to a user of the pump to communicate the condition of the pump to the user. Elastomeric pumps for infusion assemblies also are provided.

An infusion pump apparatus including a pain controlled analgesic (PCA) input device is disclosed. The infusion pump apparatus includes a housing, a pump actuator supported by the housing, and a PCA input device. The infusion pump apparatus also includes electronics configured to control the pump actuator, provide a voltage to the PCA input device, and sense an electrical signal in response to the pain controlled analgesic input device being depressed. The infusion pump apparatus further includes a controller electrically coupled to the electronics and programmed to determine whether the sensed electrical signal is discontinuous, and if the sensed signal is discontinuous, transmit an output indicative of the pain controlled analgesic input device functioning improperly.
