Abstract: A pump assembly for pumping a medication through a cannula, said pump assembly comprising a housing adapted to be attached to a skin of a patient and containing a reservoir assembly having a variable volume liquid chamber configured to contain the medication upon filling of the reservoir assembly, a variable volume gas chamber configured to contain air before filling of the reservoir assembly and a pressure chamber configured to contain a pressure generating element, the liquid chamber, gas chamber and pressure chamber are fluidly sealed with respect to each other; the liquid chamber is selectably fluidly couplable with the cannula and the gas chamber is fluidly couplable with the atmosphere.

Abstract: A stopcock, comprising a housing element defining a central bore and at least first, second and third ports; and a handle element which is selectably positionable relative to the housing element; at least one of the housing element and the handle element defining: a first fluid flow passageway communicating between two of the at least first, second and third ports; a second fluid flow passageway communicating between at least two of the at least first, second and third ports, and a fluid flow guide associated with the second fluid flow passageway, the fluid flow guide extending radially towards an inner facing wall of the central bore.

Abstract: A patch pump including a medicament reservoir having an inner surface defining an elongate piston engagement pathway, an electric motor having a rotary drive output element, a piston replaceably axially fixed to the electric motor. The piston having an outer surface arranged for sealing engagement with the inner surface of the medicament reservoir, the piston also including a rotary to longitudinal drive converter receiving a rotary drive input from the rotary drive output element of the electric motor and providing a longitudinal drive to the reservoir, thereby driving the medicament reservoir in longitudinal motion relative to the piston in which the elongate piston engagement pathway defined by the inner surface of the medicament reservoir is displaced axially and in sealing engagement with the outer surface of said piston.

Abstract: A pump assembly useful for pumping a medicament through an injection port which is removably mountable onto a patient body surface for defining a medicament injection pathway, the pump assembly including a timed pumping assembly adapted for pumping the medicament through the injection port at a given time and a removable mounting adapted for removable mounting of the timed pumping assembly onto the injection port, whereby when the timed pumping assembly is mounted onto the injection port, the medicament can be pumped by the time pumping assembly through the medicament injection pathway.

Abstract: An operator-controllable medical monitoring system including at least one medical sensor that is adapted to monitor at least one patient characteristic, a plurality of medical monitors, each including a monitor wireless transceiver and a medical information display and a patient companion assembly including a patient companion assembly wireless transceiver and a medical monitor selector wirelessly operative to initially select one of the plurality of medical monitors and to provide a monitor selection indication which is visually sensible to the operator.

Abstract: A blood oxygen saturation level (SpO2) measurement subunit employed in a wireless transceiver unit connected to a medical monitor unit. An illumination emulator is used for emulating the characteristics of an illumination source of a pulse oximeter. The emulator utilities at least part of the energy coming from the SpO2 socket of the medical monitor. Energy originally intended to energize one illumination source of the pulse oximeter, energizes the power supply circuitry. A processor is employed for processing information about pulsing arterial blood of a patient received from a patient companion assembly (PCA). A digital to analogue converter is used for converting the PCA, to analogue signal. A low pass filter (LPF), filtering the signal to form a pulsative voltage signal represents the pulsing arterial blood of the patient, and is sent to the SpO2 socket of the medical monitor for displaying and further processing.
