Abstract: A method of performing peritoneal dialysis (PD), the method comprising: delivering a PD fluid to the peritoneal cavity of a patient through a PD catheter; dwelling the PD fluid within the peritoneal cavity; and while dwelling the PD fluid, removing a biofilm from the PD catheter wall using a biofilm removing solution. The biofilm removing solution comprises: sodium citrate dihydrate; citric acid anhydrous; sodium lauryl sulfate; and water. In another aspect, a method for decontaminating a peritoneal dialysis (PD) catheter and removing a biofilm from the PD catheter and a transfer set, the method comprising: providing a biofilm removing solution; transferring the biofilm removing solution into a syringe; connecting the syringe to a transfer set of the PD catheter; and filling the transfer set and the PD catheter with the biofilm removing solution.

Abstract: A peritoneal dialysis system includes a control unit configured to (i) store a sleep state pattern for the patient, (ii) begin a patient drain followed by a patient fill when at least one sensor indicates that the patient is in a deep sleep state, (iii) extend a dwell period if the sleep state pattern indicates that the patient will enter a subsequent deep sleep state within a first time duration after a programmed dwell period, and (iv) shorten the dwell period if the sleep state pattern indicates that the patient will leave the deep sleep state within a second time duration after an end of the programmed dwell period. The system alternatively or additionally assesses or records a stress level of and/or a fluid/caloric intake by the patient and takes actions accordingly.

Abstract: Methods and apparatuses for peritoneal catheter placement are disclosed herein. An example method includes using a puncture device to create an access hole to a patient's peritoneal cavity. The puncture device includes a lumen that enables a guidewire to be inserted into the peritoneal cavity. The puncture device is then replaced with a catheter, which is inserted along the guidewire. A surgical seal is next applied to connect the catheter to adjacent patient muscle tissue. After the guidewire is removed, a tunneling device creates a pathway through fat tissue to anchor the catheter. An end of the tunneling device is aligned with an external piercing device to pierce the patient's skin from the outside, creating a catheter exit hole. An end of the catheter is connected to the tunneling device and pulled through the exit hole, thereby enabling the catheter to be connected to peritoneal dialysis tubing for a treatment.

Abstract: A trocar for peritoneal dialysis is disclosed herein. An example trocar includes a conduit having two or more parallel lumens and a head connected to a first end of the conduit. The head includes two (or more) parallel lumens that are aligned respectively with the parallel conduit lumens and includes at least one of a gasket or a seal for each lumen. The trocar also includes a coupler connected to the head. The coupler includes two (or more) parallel lumens that are aligned respectively with the parallel lumens of the head. The coupler includes a coupling mechanism for each lumen for securing surgical tools in place after insertion into a patient. The trocar may also include an obturator having a shaft that is removably inserted through the coupler, head, and conduit to protrude from a second end of the conduit.

Abstract: A servicing regime for a disposable set of a medical fluid therapy machine is disclosed. In an example, a medical fluid delivery system includes a medical fluid therapy machine operating with a disposable set over multiple treatments to mix for each treatment at least one concentrate with purified water to form a medical fluid. The medical fluid delivery system also includes a sensor configured to measure an accuracy of the medical fluid mixed by the medical fluid therapy machine. The sensor is configured to produce a mixing accuracy output. The medical fluid delivery system further includes a computer programmed to analyze the mixing accuracy output provided by the sensor to determine whether the disposable set needs to be replaced.

Abstract: A medical fluid delivery system includes: a medical fluid delivery machine including a component having at least one of associated output data or associated test data; at least one of a (i) component output replacement limit and a component output soft limit for the component or (ii) a component testing replacement limit or a component testing soft limit for the component; and a computer programmed to store at least one of (i) or (ii), and for (i) analyze the output data to provide a first indication of how well the component is performing relative to the component output replacement limit and the component output soft limit, and for (ii) analyze the test data to provide a second indication of how well the at least one component is testing relative to the component testing replacement limit and the component testing soft limit.
