Various embodiments of a device for splitting fluid substances and methods thereof are described. In one example, a device for splitting fluid substances among syringes includes an input port, a number of output ports, and a fluid distribution network. The fluid distribution network is formed to convey a fluid substance from the input port to the output ports. The fluid distribution network can include a number of fluid distribution channels for conveying the fluid substance from the input port to the output ports. The fluid distribution channels can be formed in a star configuration, in one example, although other configurations are possible. The device provides a more efficient way to fill smaller syringes during procedures, such as fat grafting procedures. The device can be used to fill a number of syringes concurrently, decreasing the time required to perform an operation, among other benefits.

A medical treatment system, such as a peritoneal dialysis system, may include a control and other features to enhance patient comfort and ease of use. For example, a cycler device may include a heater bag receiving section and a lid mounted to cover and uncover the heater bag receiving section, potentially enabling faster heating of a dialysate. A user interface may be moveable to be received into the receiving section and covered by the lid, if desired. The system may detect anomalous conditions, such as tilting of a housing of the system, and automatically recover without terminating a treatment. The system may include noise reduction features, such as porting pneumatic outputs to a common chamber, and others. The system may also automatically detect any one of several different solution lines connected to the system, and control operation accordingly, e.g., to mix solutions provided by two or more lines and form a needed dialysate solution. A cassette control surface may be arranged to have one or more ports that can detect a presence of a liquid, e.g., to identify if a cassette is leaking or has otherwise been compromised.

A method for controlling fluid ratio accuracy during a dual flow injection with a powered injection system is described. The method includes predicting a first capacitance volume of a first syringe comprising a first medical fluid and a second capacitance volume of a second syringe comprising a second medical fluid with a first capacitance correction factor and a second capacitance correction factor, respectively, selecting a ratio of the first medical fluid and the second medical fluid to be administered to a patient in the dual flow injection, determining a relative acceleration ratio of a first piston of the first syringe and a second piston of a second syringe based on the predicted first capacitance volume and the predicted second capacitance volume, wherein the relative acceleration ratio is selected to maintain the selected ratio of the first medical fluid and the second medical fluid during the dual flow injection, and injecting a mixture of a first medical fluid and a second medical fluid having the selected ratio with the powered injection system.

Valves and medication delivery systems including valves are described herein. A valve includes a valve body and a valve element. The valve body defines a first flow path, a second flow path, and a catheter flow path. The valve element is disposed within the valve body, wherein the valve element is configured to permit fluid communication between the first flow path and the second flow path in a priming position, and is configured to permit fluid communication between the first flow path and the catheter flow path in a dispensing position.

A mount provides a structure that facilitates coupling of a nebuliser downstream of a humidifier chamber and upstream of a conduit that delivers conditioned breathing gases to a patient or user. The mount can couple together a chamber, a nebulizer and a conduit.

An adapter system for facilitating collection of colostrum from a breast may include an adapter, a removable reservoir and a hand-expression funnel. The adapter may include a first open end for connecting to a breast shield of a breast pump system, a second open end for connecting to a breast pump connector of the breast pump system, and a third open end, disposed between the first and second open ends. The removable reservoir may include a wide end for removably attaching to the third open end and a narrow end for attaching to a colostrum delivery device. The hand-expression funnel may include a wide end for receiving colostrum and a narrow end for attaching to the colostrum delivery device. In some embodiments, the colostrum delivery device is a syringe.
