MEDICAL TREATMENT SYSTEM AND METHODS USING A PLURALITY OF FLUID LINES

摘要

A medical treatment system, such as peritoneal dialysis system, may include control and other features to enhance patient comfort and ease of use. For example, a peritoneal dialysis system may include patient line state detector for detecting whether a patient line is primed before it is to be connected to the patient. The patient line state detector can also the ability to detect whether a patient line has been properly mounted for priming. Both patient line presence/absence and fill state can be determined using an optical system, e.g., one that employs a single optical sensor.

主权项

1. A tubing state detector for detecting the presence or absence of a tubing segment, comprising:
a first light emitter having a first optical axis directed toward a space in which a tubing segment is to be positioned; a second light emitter having a second optical axis directed toward the space, the second light emitter being adjacent the first light emitter; and an optical sensor positioned on a side of the space opposite the first and second light emitters and arranged to receive light emitted by the first and second light emitters to determine a presence or absence of a tubing segment in the space.
