The invention generally relates to a continuous anesthesia nerve conduction apparatus and method thereof, and more particularly to a method and system for use in administering a continuous flow or intermittent bolus of anesthetic agent to facilitate a continuous or prolonged nerve block. In one embodiment, the apparatus includes a sheath having a proximal end, a distal end and at least one lumen extending from the proximal end to the distal end. The sheath also includes an embedded conductive element for transmitting an electrical signal from a proximal portion of the sheath to a distal portion of the sheath. A cannula is arranged in the at least one lumen of the sheath and has a distal end protruding from a distal portion of the sheath. The cannula is electrically coupled to at least a portion of the embedded conductive element and is configured to provide nerve stimulation.

A patch-sized fluid delivery device may include a reusable portion and a disposable portion. The disposable portion may include components that come into contact with the fluid, while the reusable portion may include only components that do not come into contact with the fluid. Redundant systems, such as redundant controllers, power sources, motor actuators, and alarms, may be provided. Alternatively or additionally, certain components can be multi-functional, such a microphones and loudspeakers that may be used for both acoustic volume sensing and for other functions and a coil that may be used as both an inductive coupler for a battery recharger and an antenna for a wireless transceiver. Various types of network interfaces may be provided in order to allow for remote control and monitoring of the device.

A method for filling a reservoir a filling assembly having a needle, and a fluid. The reservoir is in a disposable housing assembly with a septum fluidly connected to the reservoir, a septum access assembly having a first position covering the septum and a second position providing access to the septum, and a bias mechanism for biasing the septum access assembly to the first position. The method includes piercing the septum with the needle, inserting fluid to the reservoir through the needle, contacting the filling assembly to the septum access assembly, and removing the needle from the septum. Removing the needle from the septum allows the bias mechanism to move the septum access assembly from the second position to the first position. The disposable housing assembly is attached to a reusable housing assembly.

A method of infusing liquid medicaments including insulin via an insulin pump, includes identifying an insulin delivery protocol associated with ingestion of carbohydrates wherein the insulin delivery protocol is likely to lead to a postprandial drop in blood glucose to a level below a basal level, then proposing at least one alternative insulin delivery protocol to inhibit the postprandial drop in blood glucose by delivering a metered amount of insulin that is appropriate to facilitate the metabolism of the carbohydrates without the postprandial blood glucose level drop. The invention further includes querying the patient as to whether to apply the alternative insulin delivery protocol, receiving instructions from the patient in response to the query, and applying the alternative insulin delivery protocol following receiving instructions from the patient to apply the alternative insulin delivery protocol.

An apparatus for determining the volume of fluid dispensed. The apparatus has an acoustic volume sensor that acoustically excites a reference volume and a measurement chamber with a loudspeaker and measures the acoustic response with microphones acoustically coupled to the reference and the measurement chamber. The loudspeaker and sensing microphones are connected to the measurement chamber by separate ports. A detachable dispensing chamber is coupled to the acoustic volume sensor. The volume of the fluid dispensed is determined by a processor based on the acoustic response of the microphones to acoustic excitement by the loudspeaker.
