The present invention relates to a system for flushing a medical device, comprising a multi-port valve for controlling the delivery of flushing fluids, the multi-port valve connected to a source of pressurised flushing gas; a fluid outlet for coupling flushing fluids to the medical device; and, a gas-driven pump connected to the fluid outlet, wherein, in a first configuration, the multi-port valve couples a flow of gas from the source of pressurised flushing gas to the fluid outlet, and wherein, in a second configuration, the multi-port valve couples a flow of gas from the source of pressurised flushing gas to the gas-driven pump to drive the gas-driven pump thereby to provide a flow of flushing liquid to the fluid outlet.

A device for injecting a therapeutic agent into an ocular implant at least partially implanted in an eye including an injection lumen providing a pathway for injecting the therapeutic agent into the implant; an outlet lumen providing a pathway for pre-existing fluid in the ocular implant to exit the implant; and a collection chamber fluidly coupled to the outlet lumen that provides a first fluid outflow resistance and a second fluid outflow resistance. The first fluid outflow resistance is lower than a first resistance to outflow of the implant. The second fluid outflow resistance is greater than a force imparted onto the implant by intraocular pressure of the eye. Injection of therapeutic agent into the implant via the injection lumen causes the pre-existing fluid to exit the implant and enter the collection chamber via the outlet lumen and causes a second pre-existing fluid to displace from the collection chamber.

An ion-exchange membrane electrolysis device includes an ion-exchange membrane electrolytic cell and an integrally formed integrated flow channel device.

The gas delivery apparatus (1) comprises a deformable reservoir fed with gas, a control unit with microprocessor which controls a valve device for controlling the flow rate of gas, a pressure sensor configured to perform gas pressure measurements at the respiratory interface (10) and to supply the gas pressure measurements to the control unit, a flow rate sensor to measure the flow rate of gas supplied and to supply the gas flow rate measurements to the control unit, and alarm means. The control unit is configured to estimate the leaks at the respiratory interface on the basis of the measurements of pressure and of flow rate, in order to ensure a correct concentration of the therapeutic gas in the respiratory interface.

A gas mixture apparatus includes a measurement control system, an activation system, a pressurized chamber with one or more gases, and a mixing chamber. A filter can be preattached to the outlet of the mixture apparatus, allowing excess gas to be discharged therethrough and then atmospheric air to be drawn into the mixture apparatus through the filter for creating a therapeutic gas mixture.

The invention relates to a gas delivery apparatus comprising an internal gas passage, a deformable reservoir, a valve device arranged upstream of the deformable reservoir and a control unit with microprocessor controlling the valve device in order to set or adjust the gas flow. A pressure sensor performs gas pressure measurements in a respiratory mask and supplies them to the control unit. The control unit compares the pressure measurements to a pressure threshold value and controls the valve device in order to adjust the gas flow as a function of this comparison, particularly in order to increase the flow when the pressure measured is below the threshold value.
