A system for regulating fluid flow having a processor configured to reduce image noise is provided. The system includes an image sensor to capture an image of the drip chamber. The processor captures the image of the drip chamber using the image sensor, performs an edge detection on the image to generate a first processed image, and performs a Boolean-operation on a pixel on a first side of an axis of the first processed image with a corresponding pixel on a second side of the axis of the first processed image to generate a second processed image.

An infusion pump includes a housing with a door pivotally mounted to the housing, a tube channel on the housing configured to hold a tube in the infusion pump, a pumping mechanism including a shuttle, and a slide clamp ejection device.

A fluid handling cassette, such as that useable with an automated peritoneal dialysis (APD) cycler device or other infusion apparatus, may include a generally planar body having at least one pump chamber formed as a depression in a first side of the body and a plurality of flowpaths for a fluid that includes a channel. A patient line port may be arranged for connection to a patient line and be in fluid communication with the at least one pump chamber via at least a first one of said flowpaths, and an optional membrane may be attached to the first side of the body over the at least one pump chamber. In one embodiment, the membrane may have a pump chamber portion with an unstressed shape that generally conforms to the depression of the at least one pump chamber in the body and is arranged to be movable for movement of the fluid in a useable space of the at least one pump chamber. One or more spacers may be provided in the at least one pump chamber to prevent the membrane from contacting an inner wall of the at least one pump chamber. The patient line, a drain line, and/or a heater bag line may be positioned to be separately occludable in relation to one or more solution lines that are connectable to the cassette.

A clamping mechanism (30) for clamping a flexible tube comprises two rotatable bobbins (22, 32), each with a tube-engaging surface portion (24) defining boundaries of: a free space through which a tube may extend. The shape of: the tube-engaging surface portion (24) changes around the bobbin circumference, such that axial rotation of the bobbins (22, 32) reduces the free space and thereby squeezes the tube. This allows the flow through the tube to be altered dependent on the rotation of: the bobbins.

A breaker device (1) for acting onto a closure element (40) of a medical tubing (4) comprises a drive arrangement (2) having an electric drive device (20) and a drive element (23) driven by the drive device (20), and a breaker module (3) which is arrangeable on the drive arrangement (2). The breaker module (3) comprises a housing (30), a movable part (31) movably arranged on the housing (30) and a breaking element (315) for acting onto the closure element (40) of the tubing (4), wherein the breaker module (3) in an attached state is placed on the drive arrangement (2), the drive element (23) being in operative connection with the movable part (31) in the attached state such that a movement of the drive element (23) causes the movable part (31) to move for actuating the breaking element (315). A control device (5) serves for controlling the electric drive device (20) for driving the drive element (23). Herein, the control device (5) is constituted to control, during a detection routine, the electric drive device (20) to drive the drive element (23) in order to move the movable part (31), wherein the control device (5) is further constituted to analyse at least one feedback signal received during the detection routine for determining a type of the breaker module (3), the feedback signal being indicative of a movement of the movable part (31) during the detection routine.

Tissue access devices and methods of using the same are disclosed. The devices can have a sensor configured to occlude a flow path by deflecting a membrane into the flow path when the devices become dislodged from tissue. The sensor can be configured to partially or fully occlude the flow path. The sensor can have a spring. The spring can be biased to move the sensor from a sensor first configuration to a sensor second configuration when a force applied by the sensor first surface against a non-sensor surface changes from a first force to a second force less than the first force. The membrane can be deflected into the flow path when the sensor is in the sensor second configuration.

A drug solution injection controller 10 includes a sub-reservoir 24 connected via a sub-line 26 to a main line 14 for performing continuous administration of a drug solution such that rapid administration of the drug solution from the sub-reservoir 24 by self-operation is enabled, and comprises: a priming flow path 46 configured to perform priming on at least one of the main line 14 and the sub-line 26; a closing mechanism 48 configured to close the priming flow path 46; and a connector holding part 84 holding a terminal connector 18 connected to the main line 14. Holding of the terminal connector 18 by the connector holding part 84 is allowed to be released due to operation of an operation switch 50 configured to activate the closing mechanism 48.

Components for a medical infusion fluid handling system, such as an APD system, in which one or more lines (such as solution lines), spikes or other connection ports may be automatically capped and/or de-capped. This feature may provide advantages, such as a reduced likelihood of contamination since no human interaction is required to de-cap and connect the lines, spikes or other connections. For example, a fluid handling cassette may include one or more caps that cover a corresponding spike and include a raised and/or recessed feature to assist in removal of the cap from the cassette. A solution line cap may include a hole and recess, groove or other feature to engage with a spike cap and enable removal of the cap.
