A blood glucose control system can generate an indication of total carbohydrate therapy over a period during use by a subject. The system can be connected to a medicament pump configured to deliver insulin therapy, other types of medicament therapy, or a combination of medicament therapies to the subject. The system can determine an amount of a counter-regulatory agent to respond to an impending risk of hypoglycemia or an episode of hypoglycemia and determine a dose of carbohydrate therapy based at least in part on the amount of the counter-regulatory agent. The system can track determined doses of carbohydrate therapy to generate the indication of total carbohydrate therapy over the period.

Hemodialysis systems are described. A hemodialysis system may include a dialysate flow path through which dialysate is passed from a dialysate reservoir, which includes a valved vent to atmosphere, to an ultrafilter. The dialysate flow path includes a pneumatically actuated diaphragm-based dialysate pump for pumping fluid from the dialysate reservoir to the ultrafilter. The hemodialysis system may include a controller for controlling pneumatic actuation pressure delivered to the dialysate pump and at least one valve connecting the dialysate reservoir vent to the atmosphere. The hemodialysis system may be configured to actuate the dialysate pump and the at least one valve to introduce air into the dialysate flow path and expel liquid from the dialysate flow path to a drain.

A ventilator system including an oxygen delivery cylinder, an air delivery unit, connecting tubes, and a digital display unit. The system further includes a Y connector configured to mix air and oxygen, to form a gas and pass said gas towards an outlet of the system. A water manometer that is configured to monitor a pressure of the gas in the system and blow off the excess pressure of the gas. A solenoid valve that is configured to adjust an end respiratory pressure obtained from a breathing device connected to the outlet of the system. The pressure of the gas being instantly delivered to the breathing device is measured by water manometer from a dead space near the outlet, thereby enabling a dual monitoring of the gas pressure being delivered to the breathing device.

A system or apparatus may include a container configured to collect fluid from a tissue site and regulate negative-pressure from a negative-pressure source. In some embodiments, the container may include a regulator that receives negative pressure directly from an unregulated negative-pressure source, such as a wall-suction outlet. The regulator may regulate down the pressure delivered to a collection chamber in the container, which may in turn be connected to a tissue site.

A repeater system may control a pump by using a repeater and a user interface. An adhesive patch system may be used for affixing a pump or other object to a human body. Such an adhesive patch system may include two sets of adhesive members, each member including an adhesive material on at least one side so as to attach to the body. The members of the first set are spaced to allow the members of the second set to attach to the body in spaces provided between the members of the first set, and the members of the second set are spaced to allow members of the first set to detach from the body without detaching the members of the second set. Also, fill stations and base stations are provided for personal pump systems.

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.

An apparatus for starting operation of a motor of an implantable blood pump including a memory storing one or more default parameters for at least one of controlling and monitoring the startup operation. A processor operatively coupled to the motor is included, the processor is configured to: commence the startup operation based on the one or more default parameters; detect an error during the startup operation; adjust at least one of the one or more default parameters in response to the detected error; store the at least one adjusted parameter in the memory; and commence subsequent startup operations based at least in part on the at least one adjusted parameter.

Systems, apparatuses, and methods for utilizing a dressing having a single manifold fluidly coupled to at least two therapy units in a negative-pressure therapy and/or instillation therapy environment as set forth herein. In one example embodiment wherein the therapy system comprises two therapy units, apparatus and methods may be utilized for alternately applying pressure or fluids to a single tissue site to more quickly remove large amounts of fluid from the tissue site.

The present invention relates to a gas control device (10) for a ventilator, comprising a first gas channel (11) having a non-return valve (19), a second gas channel (12) and a switching apparatus (13), wherein the first gas channel (11) has an opening (14) for the outflow of gas with a seal (15) and a closure cap (16), wherein the switching apparatus (13) is configured to guide the gas stream of the first gas channel (11) past the non-return valve (19) in the event of a blockage/malfunction of the non-return valve (19). The present invention also relates to a ventilator comprising a gas control device (10) according to one of the above-mentioned features.
