Abstract: Systems and methods for detecting administration of a dose of a medicament are described. A medicament dispensing system may include a cap sensor to detect removal of a cap from a container holding a medicament, an orientation sensor to detect an orientation of the container, and a force sensor to detect application of forces to the container. The system may determine that a dose has been administered based on detection of, in order, removal of the cap, movement of the container to an administration orientation, and application of a force to the container greater than a threshold force.

Abstract: A reconstitution assembly includes a housing including a lower sleeve and an upper sleeve, including a first container and a second container disposed vertically opposite the first container. A transfer set assembly is disposed within the housing between the first container and the second container. The transfer set assembly includes an upper spike housing and a lower spike housing, with a flow path defined through the upper spike housing and the lower spike housing. The transfer set assembly is configured to access contents of the first container and then upon the activation of a triggering mechanism, create a fluid pathway between the first container and the second container. The triggering mechanism ensures the transfer set assembly sequentially accesses the contents of the first container before accessing the contents of the second container. The disposition of the first container activates the triggering mechanism.

Abstract: A self-contained electrolocation apparatus of the present invention includes an electrically conducting needle cannula having a proximal end, a distal end and a hollow bore therethrough. The invention further includes a non-conductive tube having a proximal end and a distal end, the tube being mounted over the needle cannula so that the distal end of the non-conductive tube is proximal to the distal end of the needle cannula. The non-conductive tube has a conductive layer thereon, whereby the needle cannula and the conductive layer respectively define first and second conductors coaxially spaced from one another by the non-conductive tube. There is a grip fixedly attached to the needle cannula for manipulating the apparatus. The grip has an electrical stimulus generator circuit within it that is electrically connected to the first conductor and the second conductor.

Abstract: An electrolocation apparatus is provided for locating a nerve to which anesthesia may be delivered. The apparatus includes a needle assembly having an electrically conductive needle cannula non-conductive tube secured over the needle cannula, and a conductive plating on the tube. The conductors are connected to a stimulator that generates alternating high and low charge pulses with a constant low current level. The high charge pulses generate noticeable muscle twitches immediately after insertion of the needle into the patient. Muscle twitches responsive to the high charge pulses will peak in magnitude, and muscle twitches responsive to the low charge pulses will become observable as the needle approaches the targeted nerve, and will be indistinguishable from the muscle twitches responsive to the high charge pulses when the needle is in a position for administration of anesthetic.
