Goal-directed fluid therapy

Номер: US20120259308A1

Принадлежит: Individual

A method includes setting a hydration goal and administering a diuretic to the patient to induce increased urine flow and collecting urine expelled by the patient. The amount of urine expelled by the patient is determined based on the collected urine. The patient is infused with fluid from a fluid source. The amount of fluid infused into the patient is determined. Diuresis is induced by automatically and continuously adjusting the amount of fluid infused into the patient from the fluid source to meet the hydration goal based on the set hydration goal, the determined amount of urine expelled by the patient and the fluid infused.

A plasmapheresis system and a method for operating a plasmapheresis system are provided by which the volume/weight of anticoagulated plasma that is collected is optimized. In one example, a nomogram is provided that utilizes the donor's hematocrit to calculate the volume/weight of raw plasma within a plasma product having the maximum volume permitted by the FDA nomogram. In a plasmapheresis procedure having multiple collection phases followed by a reinfusion cycle in which concentrated red blood cells are returned to the donor, the volume of plasma product to be collected is calculated prior to the start of each collection cycle to account for the donor's increasing hematocrit, thus resulting in a greater total volume of plasma product to be collected during the plasmapheresis procedure.

Improvements in fluid volume measurement systems are disclosed for a pneumatically actuated diaphragm pump in general, and a peritoneal dialysis cycler using a pump cassette in particular. Pump fluid volume measurements are based on pressure measurements in a pump control chamber and a reference chamber in a two-chamber model, with different sections of the apparatus being modeled using a combination of adiabatic, isothermal and polytropic processes. Real time or instantaneous fluid flow measurements in a pump chamber of a diaphragm pump are also disclosed, in this case using a one-chamber ideal gas model and using a high speed processor to obtain and process pump control chamber pressures during fluid flow into or out of the pump chamber. Improved heater control circuitry is also disclosed, to provide added or redundant safety measures, or to reduce current leakage from a heater element during pulse width modulation control of the heater. Improvements are also disclosed in the application of negative pressure during a drain phase in peritoneal dialysis therapy, and to control the amount of intraperitoneal fluid accumulation during a therapy. Improvements in efficiency are also disclosed in the movement of fluid into and out of a two-pump cassette and heater bag of a peritoneal dialysis cycler, and in the synchronization of the operation of two or more pumps in a peritoneal dialysis cycler or other fluid handling devices using a multi-pump arrangement.

A method and apparatus for monitoring and/or managing adherence to a medication regimen that involves use of a sensor. Dispensing medicine from a container commonly involves motion of the container, which can be a distinctive motion. In some embodiments, a processor monitors motion sensor data from a motion sensor that is physically coupled to the container, such that the motion sensor and the container move in unison. A processor analyzes the sensor data to determine physical movement of the container. When the determined movement matches the distinctive motion of medicine being dispensed, the processor can determine that medicine has been dispensed. A computer system can compare the dispensed medication to a planned medication regimen to determine a state of compliance to the medication regimen. The computer system can take an action based on the compliance state, such as sending a message indicating the compliance state to a medical professional.

Apparatus, systems and methods are disclosed relating to certain aspects of blood processing, collecting or storing, including method and system for automated authentication, processing device with scanner, blood container with two dimensional barcode, blood collection containers, blood container label and related tracking method, integrated container system, and processing device with sterile connection device. 154-. (canceled)55. A single blood collection container comprising:a pair of facing flexible plastic sheets sealed together along a seal line to define an internal cavity for receiving blood, the cavity having a first end, a second end, a first side and a second side; an inlet port and outlet port extending through the seal line at the first end for flowing blood into and from the container, the seal line being uninterrupted except for the inlet and outlet ports;inlet tubing having a first end connected to the inlet port and a second end for connection to a vascular access member; andoutlet tubing having a first end connected to the outlet port and a second sealed end for sterile connection to a blood processing set on-site by a sterile connection device.56. The single blood collection container of wherein the outlet port is located at the first end approximately midway between the first and second sides.57. The single blood collection container of including at least one hanging aperture along the first or second side.58. The single blood collection container of any one of having at least two spaced apart hanging apertures along at least one of the first and second sides.59. The single blood collection container of in which the at least one hanging aperture is located along the first side and the inlet port is located between the outlet tube and the second side.60. The single blood collection container of carrying a two dimensional bar code on an exterior surface of the container claim 55 , the barcode encoding at least a manufacturer's part number or ...

The present specification describes systems and methods for detecting an occlusion in a tubing carrying a patient's blood through a manifold and into a dialyzer in a dialysis system. A controller measures pressures value of the blood at a predetermined point after exiting the manifold and before entering the dialyzer, calculates a historical running average, calculates a weighted sum of the most recent pressure values, and determines whether to trigger an occlusion alarm based on a function of the historical running average and the weighted sum of the most recent pressure values. 1. A dialysis system comprising:a manifold comprising an enclosed blood flow path, wherein said blood flow path comprises a blood inlet port, a blood outlet port, and a flexible tube positioned between said blood inlet port and blood outlet port;a pressure sensor in physical communication with manifold at a position proximate said blood outlet port;a non-transient memory in data communication with said pressure sensor and configured to store pressure values generated and transmitted by said pressure sensor;at least one pump in physical contact with said flexible tube and configured to pump blood from a patient's body, through a tube, and through said blood flow path; and receive said pressure values;', 'determine an average of n pressure values, where n is a subset of said pressure values;', 'determine a sum of m pressure values, where m is a subset of said pressure values and where m Подробнее
