Blood Treatment Systems
In one aspect, a system includes a blood treatment machine; a dialyzer configured to be coupled to the blood treatment machine, the dialyzer including a dialyzer housing defining a blood inlet and a blood outlet; a bundle of hollow fibers within an interior of the dialyzer housing; a pumping device drivable to force blood received from the blood inlet through lumens of the bundle of hollow fibers and out the blood outlet; a dialysate inlet port in fluid communication with a dialysate flow path that includes space in the interior of the dialyzer housing between the bundle of hollow fibers; and a dialysate outlet port in fluid communication with the dialysate flow path. The system further includes a fluid conditioning system configured to (i) prepare and supply fresh dialysate to the dialyzer via the dialysate inlet port, and (ii) receive spent dialysate from the dialyzer via the dialysate outlet port, recycle the spent dialysate, and supply the recycled dialysate to the dialyzer via the dialysate inlet port.
PERITONEAL DIALYSIS SYSTEM
An assembly includes first and second assemblies, the first assembly including a frame defining a recess, a first plate disposed within the recess, and a bellows disposed between the first plate and an inner surface of the frame. The second assembly includes a second plate configured to be opposite the first plate when the first assembly is in a closed position relative to the second assembly. The first assembly is configured to move relative to the second assembly between an open position and the closed position, and a latch assembly configured to hold the first assembly to the second assembly in the closed position. The bellows is configured to inflate to apply a force to the first plate towards the second plate when the first assembly is in the closed position.
Mechanical kidney transplant
A mechanical kidney transplant designed may include a four modules designed to interconnect to clean blood. The first module may include a plurality of pump modules and a resin gel regeneration module, wherein the first module is operatively attached to a patient's iliac artery, iliac vein, and bladder. The second module may be operatively attached to the first module and may include storage and pump systems. The third module may be operatively attached to the first and fourth modules and may include a housing with ports for inflow/outflow of the blood and the physiologic resin gel between the first module and the fourth module. The fourth module may include at least one dialyzer fiber sized to accommodate a volume of blood flowing therethrough and an area surrounding the dialyzer fiber may be sized to accommodate a volume of a physiologic resin gel flowing counter current to the blood.
Handle for a Medical Device
The invention relates to a handle for a medical device (10) which has a dual function: gripping (12) the medical device and holding a functional component of a medical system against the medical device, preferably a dialysis filter (4).
RECIRCULATION MEASUREMENT BY MEANS OF DIFFUSION EQUILIBRIUM
An extracorporeal blood treatment machine includes a dialyzer and a sensor device downstream of the dialyzer on a dialysis fluid side. The machine is connected to a control and computing unit configured to qualitatively and quantitatively determine at least one preferably selected or selectable blood component in the used dialysis fluid. The control and computing unit is adapted to put the machine into a mode in which a dialysis fluid amount is confined within the dialyzer at least until the concentrations of the blood component on the dialysis fluid side and on the blood side of the dialyzer are in equilibrium, and thereupon to switch the machine into a mode in which the dialysis fluid flow is permitted to leave the dialyzer to feed the confined dialysis fluid amount as a dialysis fluid bolus to the sensor device for determining the blood component concentration contained in the bolus.
Blood treatment systems and related components and methods
This disclosure relates to a blood treatment system including a blood treatment machine, a dialyzer configured to be coupled to the blood treatment machine, a blood line having a first end configured to be connected to the dialyzer and a second end configured to be connected to a needle for insertion into a patient, and one or more sensors operable to transmit, to the blood treatment machine, data related to tension along the blood line. The blood treatment machine is configured to take action in response to the data received from the one or more sensors.
EXTRACORPOREAL BLOOD TREATMENT MACHINE COMPRISING A POKA-YOKE FOR A PRESSURE SENSOR
An extracorporeal blood treatment machine includes a blood treatment device, a conveying device for conveying blood through the blood treatment device, and a connection mask designed to interchangeably receive a tube set in a predefined arrangement. The tube set has pressure-monitoring lines that branch off from the tube set and can be connected to pressure sensor connections located on the connection mask. The pressure sensor connections are spaced apart and positioned so as to match the tube set such that, when the tube set is mounted in the predefined arrangement on the connection mask, each pressure-monitoring line, owing to its limited length and the predefined arrangement of the associated branch on the blood treatment machine, can be connected exclusively to only one of the pressure sensor connections. A corresponding tube set is used with the extracorporeal blood treatment machine.
SECURING CONNECTIONS TO DIALYZERS
The present teachings include techniques for securing a connection to a dialyzer or the like—e.g., securing the junction between a dialyzer port and a connector (e.g., a DIN connector) that couples the port to tubing of an extracorporeal circuit of a hemodialysis system. To this end, a locking device may engage both a DIN connector and a portion of the dialyzer, such as the cap or an adapter engaged therewith. The locking device may include an interior void sized and shaped to accommodate winged portions (or other portions) of the DIN connector to mitigate rotation thereof relative to the port to which it is engaged. Further, the locking device may be used to ensure that coupling between the DIN connector and the port is proper and secure. In this manner, a locking device can mitigate leaks, which can be catastrophic during a hemodialysis treatment or the like.
Peritoneal dialysis machine
A peritoneal dialysis machine has at least one mount for fixing one or more sections of a hose set for conducting a dialysis solution from and/or to a patient. A first pivot axle is provided about which the mount can be pivoted from a first position into a second position.
Fluid circuit for delivery of renal replacement therapies
A portable dialysis cabinet for use in dialysis. The portable dialysis cabinet can have a size and weight that facilitates easy movement of the cabinet from one location to another with relative ease. The portable dialysis cabinet can have additional features necessary to facilitate portability, such as wheels and a handle. In general, the portable dialysis cabinet can contain all the necessary components for performing a dialysis session.
