Disclosed herein is an automated urinary output monitoring system including urine collection assembly that includes a first drainage tube coupled between a urinary catheter and an interim container, and a second drainage coupled between the interim container and a final container. A scale measures the weight of urine collected in the final container and a display depicts the volume of urine collected in the final container. A vacuum pump can be coupled with the final container to draw urine from the interim container into the final container, and an air vent can isolate the patient from the vacuum within the final container. The system can be configured to wirelessly transmit urine volume data to an external computing device. A gyroscope can be coupled with the scale to determine the orientation of the scale. Logic of the system can calculate urine volume and correlate with the time of day.

A computer-implemented method comprises providing a fluid circuit comprising fluid pathways configured to mount and associate with a durable processing device comprising a pressure sensor in communication with a controller and a fluid pathway. A container is connected to the pressure sensor and may receive a volume of fluid. A change in pressure values between a first and second time is measured from when the volume of fluid is not in communication with the pressure sensor to when the volume of fluid is in communication with the pressure sensor, the volume of fluid within the container or a presence or absence of a fluid connection to the fluid pathway based on the change in pressure values is determined, and a response action is executed if the volume of fluid within the container is not within an authorized volume range for the time period, or if a fluid connection is unauthorized.

A portable hemodialysis system is provided including a dialyzer, a closed loop blood flow path which transports blood from a patient to the dialyzer and back to the patient, and a closed loop dialysate flow path which transports dialysate through the dialyzer. In addition, the hemodialysis system includes two reservoirs which can be alternately placed in the dialysis flow path using various controllable fluid valves. The weight, and therefore the level of dialysate, of each reservoir is measured by a preferred level sensor having a strain measuring device which includes a load cell and a tilt sensor. The load cell and tilt sensor are electrically connected to a processor for sending force and tilt measurements to the processor. The processor may analyze the tilt measurements to correct for any inaccurate measurements of the load cell caused by the tilt.

A dialysis fluid system includes a dialysis fluid inlet; a dialysis fluid outlet; a pump positioned and arranged to pump dialysis fluid through the dialysis fluid inlet and the dialysis fluid outlet; and an inductive heater located between the dialysis fluid inlet and the dialysis fluid outlet, the inductive heater including a fluid flowpath positioned and arranged to receive non-heated dialysis fluid from the dialysis fluid inlet and to output heated dialysis fluid to the a dialysis fluid outlet, a conductive heater element located within the fluid flowpath so as to be or act as a secondary coil of a transformer, and a primary coil of the transformer located outside of the fluid flowpath and positioned so as to magnetically induce a current into the conductive heater element, causing the conductive heater element and surrounding fluid to heat.

Aspects and embodiments of the present invention generally include a device for patient self-administration of a prescribed medication. The device makes available for administration the precise quantity of medication constituting a dose at times designated by a health care provider (HCP). Preferably, the device also detects and transmits information to a remote management system accessible to the HCP, including detected attempts to tamper with the device. Advantageously, HCPs may render oversight and control over the device and its use to mitigate risks associated with patients self-administering medication without in-person supervision. This control may include establishing prerequisites the patient must meet prior to a dose being made available, or remote deactivation of the device. This oversight by the HCP may include patient-specific and aggregate data analysis for optimization of treatment or evaluation of the safety and efficacy of a treatment. Furthermore, this oversight may be conducted via a web-based interface.

Disclosed herein are various techniques and devices for detecting a level of fluid within a fluid collection receptacle. In one embodiment, a pressure sensor connected to a bottle is provided. The pressure sensor detects air pressure in the bottle as the bottle is filled with a liquid and provides information to determine a volume of the liquid in the bottle.

Systems and methods for renal insufficiency treatment that include identifying and associating a solution container with a container support in the systems and methods are described herein. The systems and methods may associate an identified solution with an identified container support and verify compatibility of that combination with a selected treatment to reduce the likelihood for errors during setup and use of the systems and methods.

A system for delivering a medicinal fluid to a patient includes a variable volume pressure delivery chamber, a variable volume medication chamber, an optional medication reservoir, a movable delivery element, a fixed reference volume chamber, a pressure source, and a control sub-system. The variable volume pressure delivery chamber is configured to store pressure controllably. The variable volume medication chamber is fluidically isolated from the pressure delivery chamber and is configured to store medicinal fluid. The movable delivery element is disposed between the medication chamber and the pressure delivery chamber. The pressure source is coupled to the pressure delivery chamber. The control system is configured to selectively cause the pressure source to deliver pressure to the pressure delivery chamber causing the movable delivery element to apply pressure to the medicinal fluid in the medication chamber thereby causing the medicinal fluid to exit the medication chamber at an outlet along the fluid communication path to the patient.

Systems and methods for dynamically modulating aspiration in response to sensed conditions. An aspiration system can include a catheter configured to be inserted within a vasculature of the subject, a canister coupled to the catheter, a pressure source that generates a vacuum pressure through the catheter for aspirating the fluid, a sensor configured to sense a parameter associated with at least one of the catheter, the canister, or the pressure source, and a computer system coupled to the sensor. The computer can cause the pressure source to initiate the vacuum pressure throughout the catheter, receive a measurement of the parameter from the sensor, determine whether the measurement violates a threshold associated with the parameter, and modulate the vacuum pressure at the catheter tip in response to a determination that the measurement violates the threshold.
