A pressure regulation system for discharging a liquid having a predetermined liquid pressure from a liquid opening, including an elastic bag having a liquid phase and a gas phase, where the liquid opening in an operational position of the elastic bag is formed in the lower area of the elastic bag, at least two push elements, at least one drive unit and a control unit. The elastic bag has a gas opening, which extends into the gas phase. The pressure regulation system has a ventilation unit, which is connected to the control unit for communication and which connects to the gas opening of the elastic bag. The ventilation unit regulates the liquid pressure of the liquid discharged through the liquid opening by means of a gas supply into the elastic bag and/or a gas discharge from the elastic bag.

Disclosed herein is a breast pump sensor network. The breast pump sensor network includes an emitter disposed within a bodily fluid capture system and a detector disposed within the bodily fluid capture system. Further disclosed is a method for controlling the breast pump sensor network which includes emitting a beam of electromagnetic radiation within a bodily fluid capture system, detecting one or more drops of body fluid within the bodily fluid capture system, determining a bodily fluid flow rate based at least on the detected one or more drops of bodily fluid, and providing the determined bodily fluid flow rate to at least one user.

The label is attached to at least one part of the syringe and does not overlap with the marking. Also disclosed is a labeling method, kit and dispenser featuring such labels.

A method of delivering a radioactive liquid includes, performing an initialization, including; extracting at least a first amount of a radioactive liquid from a source of radioactive liquid, measuring a radioactivity level for the first amount of radioactive liquid, and performing a calibration phase. The calibration phase includes, extracting a second amount of radioactive liquid from the source of radioactive liquid wherein the second amount is calculated based on the radioactivity level of the first amount to provide a total dose of radioactive liquid having a predetermined radioactivity level, and delivering the total dose and performing at least one more calibration and delivery phases.

A dialysis machine (e.g., a peritoneal dialysis (PD) machine) can include a control unit configured to monitor an amount of fluid withdrawn from a heater bag line during a PD treatment. A processor in the control unit is configured to operate a first pump to draw fluid into a first pump chamber and measure a first fluid volume in the first pump chamber. The processor is further configured to operate the first pump and a second pump to transfer fluid from the first pump chamber to a second pump chamber, measure a second fluid volume in the second pump chamber, and determine a measured fluid volume for a single pump cycle based on the first fluid volume and the second fluid volume. The first fluid volume is correlated to the second fluid volume and, therefore, the multiple independent measurements increase an accuracy of the fluid volume measurement.

A medical infusion fluid handling system, such as an automated peritoneal dialysis system, may be arranged to de-cap and connect one or more lines (such as solution lines) with one or more spikes or other connection ports on a fluid handling cassette. This feature may reduce a likelihood of contamination since no human interaction is required to de-cap and connect the one or more lines and the one or more spikes. For example, the automated peritoneal dialysis system may include a carriage arranged to receive the one or more lines each having a connector end and a cap. The carriage may move along a first direction so as to move the connector ends of the one or more lines along the first direction, and a cap stripper may be arranged to engage with the caps on the the one or more lines on the carriage. The cap stripper may move in a second direction transverse to the first direction, as well as to move with the carriage along the first direction.

An apparatus is described for extracorporeal blood treatment (1), comprising a treatment unit (2), an extracorporeal blood circuit (8) and a fluid evacuation line (10). The apparatus comprises a control unit (21) connected with a pressure sensor (13, 14) and with a blood pump (9) and configured to move the blood pump (9), generating a variable flow (Q(t)) with a constant component (Q.sub.b) and a variable component (Qvar(t)) having a nil average value; the variable flow generates, in the expansion chamber (11, 12), a progression of the pressure that is variable over time (P(t)) with a pressure component (Pvar(t)) oscillating about an average value (P.sub.avg). The control unit receives, from the sensor, a plurality of values (P.sub.j) and calculates the average value of the pressure (P.sub.avg), acquires an estimated value of volume variation (AP) in the expansion chamber (11, 12) connected to the variable flow component (Qvar(t)), calculates, as a function of the pressure values (P.sub.j), an estimated value of pressure variation (AP) in the expansion chamber (11; 12) that is representative of the oscillating pressure component (Pvar(t)) and determines a representative magnitude of a blood level (L) in the expansion chamber (11, 12) as a function of the average value (P.sub.avg) of the pressure (P(t)), of the estimated value of volume variation (AV) and of the estimated pressure variation (AP) in the expansion chamber.

An irrigation system for providing a continuous and controlled flow of a fluid, wherein said irrigation system may include a reservoir system comprising a plurality of containers of fluid that are disposed in a predetermined radial configuration; said reservoir system has a main longitudinal axis; and a fluid transfer system in fluid connection with said reservoir system, said fluid transfer system comprising at least one fluid transfer head, adapted to transfer fluid from one of said plurality of containers to an external tubing system; wherein each of said fluid transfer heads has a mechanism adapted to radially move each of said fluid transfer heads around the main longitudinal axis and reach a position below each of the plurality of containers.

An electronic vapor device is disclosed comprising a first container for storing a vaporizable material, a vaporizer component coupled to the first container, configured for vaporizing the vaporizable material, a processor coupled to the vaporizer component, configured to control the vaporizer component in response to a disposition signal, and a network access device, coupled to the processor, configured for receiving the disposition signal from a remote server.

An infusion pump system and method with common line auto flush, wherein the infusion pump system has a first reservoir, a second reservoir, a junction, a common line having one end in fluid connection with the junction and having a terminal fluid delivery end, and an infusion pump.
