Abstract:

A graphical user interface for a medical instruments for a Renal Replacement Therapy includes a pictogram representation of cthe fluid path of an extracorporeal blood circuit that represents fluid lines, pumps and sensors. To assist the user in responding to alarms and rectifying faults in the system the source of a potential trouble is animated. The location of a trouble spot is easily identified by flashing of the corresponding element of the pictogram, change of color or thickness of a corresponding line.

Abstract:

An extracorpeal blood circuit for removal of contrast from human blood using a filter and withdrawal filter pump and a by-pass pump. The withdrawal filter blood pump operates when a contrast bolus has been detected. Otherwise the bypass blood pump maintains physiological blood flow from the coronary sinus preventing the need for deflation and re-inflation of the balloon catheter. When contrast is detected blood the bypass blood pump is stopped to prevent contrast from leaking back into the patients circulatory system via the bypass pump and CS blood flow is maintained at its physiological blood flow resulting in the heart being oblivious to the transition by the prefilter blood pump.

Abstract:

A method and apparatus are disclosed for controlling blood flow through an extracorporeal blood circuit having a controller comprising the steps of: withdrawing the blood from a withdrawal blood vessel in a patient into the extracorporeal circuit, treating the blood in the circuit and infusing the treated blood into the patient; detecting an occlusion which at least partially blocks the withdrawal or infusion of the blood; reducing the blood flow rate and the rate of filtration in response to the occlusion, and further prompting the patient to move his arm in an effort to alleviate the occlusion.

International Classification:

A61M 31/00
A61M 1/00

US Classification:

604503, 604 67, 604 31

Abstract:

A patient hydration system with an infusion subsystem which infuses fluid into a patient and a urine output measurement subsystem for measuring the amount of urine output by the patient. A controller is configured to control the infusion subsystem and is responsive to the urine output measurement subsystem. The controller includes a balancing function which controls the infusion subsystem to administer fluid infused into the patient to balance the urine output with the fluid infusion. The controller also includes a taper down function which controls the infusion subsystem to administer fluid infused into the patient at a rate less than the rate of urine output by the patient.

International Classification:

A61M 5/168

US Classification:

604503000

Abstract:

A patient hydration system with a first infusion subsystem for infusing a patient with fluid from a first source and a second infusion subsystem for infusing a patient with fluid from a second source. A urine output measurement subsystem determines the amount of urine output by the patient. A controller is responsive to the first infusion subsystem, the second infusion subsystem, and the urine output measurement subsystem and is configured to control the first infusion subsystem based on the amount of urine output by the patient and/or the amount of infused fluid measured by the second infusion subsystem.

International Classification:

A61M 5/168

US Classification:

604503, 604 66

Abstract:

A fluid replacement device and method. A console includes a weighing subsystem responsive to a first fluid source and a urine collection chamber. A pump is configured to infuse fluid from the first fluid source into a patient. A processing subsystem in the console is responsive to the weighing subsystem. Based on the weight of the first fluid source and the weight of the urine collection chamber, the patient's urine output and the amount of fluid infused into the patient from the first fluid source are determined. A user interface in the console allows the user to set a desired fluid balance for the patient and the amount of at least one additional fluid delivered to the patient. An actual fluid balance is calculated based on the determined urine output, the determined amount of fluid infused into the patient from the first fluid source, and the set amount of the at least one additional fluid delivered to the patient. The pump is controlled based on the actual fluid balance and the set desired fluid balance so the actual fluid balance becomes the same as or approximately the same as the desired fluid balance.
