  • Patent number: 12285758
    Abstract: A lab-on-a-chip cartridge includes a housing defining four separate chambers. A fluid (such as whole blood) flows through one of the chambers and into another one of the chambers, which includes a filter membrane. The filter membrane is rotated to separate a first fluid component (such as plasma) from a second fluid component (such as red blood cells), with the first fluid component passing through the filter membrane and the second fluid component not passing through the filter membrane. The separated first and second fluid components each flow into a different one of the remaining chambers, with the first fluid component contacting a lab-on-a-chip device for analyzing the first fluid component.

  • Patent number: 12257378
    Abstract: Blood is conveyed from a source into a separator, which separates at least one target blood component from the blood. The target blood component is then conveyed out of the separator, with the procedure continuing until an initial target amount of blood to be processed has been conveyed from the source into the separator and the target blood component separated from the initial target amount of blood to be processed has been conveyed out of the separator as an actual yield of the target blood component. An adjusted target amount of blood to be processed is then determined based at least in part on the difference between a target yield of the target blood component and the actual yield. The initial target amount of blood to be processed is then replaced with the adjusted target amount of blood to be processed when next executing the procedure.

  • Patent number: 12222235
    Abstract: A system for splitting a fluid includes a source support configured to support a source container of a fluid flow circuit and at least one satellite support, with each satellite support configured to support a different satellite container fluidly connected to the source container. A weight scale is associated with each of the supports. The system also includes a clamp system and a controller. The controller is configured to control each weight scale to measure a combined weight of the container and the contents of the container supported by the support associated with the weight scale. The controller is configured to control the clamp system to selectively allow and prevent fluid flow from the source container to each satellite container based at least in part upon the weights measured by each weight scale. Fluid flow continues until the contents of each container have reached a target volume.

  • Patent number: 12214366
    Abstract: A prismatic reflector is provided for incorporation into a centrifugal separation chamber. The prismatic reflector is formed of a light-transmissive material and includes inner and outer walls and first and second end walls. The inner wall is configured to receive light traveling along an initial path and transmit the light to the first end wall, with the first end wall receiving the light transmitted through the inner wall and directing the light toward the second end wall in a direction that is angled with respect to the initial path. The second end wall receives the light from the first end wall and transmits the light out of the prismatic reflector. The initial path of the light may be in a direction toward a rotational axis of the centrifugal separation chamber, with the prismatic reflector redirecting the light into a direction substantially parallel to the rotational axis.

  • Patent number: 12204962
    Abstract: Printing a code on a flexible medical solution container includes providing a flexible medical solution container which is at least partially light transmissive, storing in a memory circuit a code comprising numbers and translating the code comprising numbers using a bar code symbology, the bar code symbology defining dark areas and light areas. The method includes applying a light-reflective ink to the container based on the bar code symbology, wherein the light-reflective ink is applied in areas defined by the dark areas, and applying a light-absorbing ink to the container based on the bar code symbology, wherein the light-absorbing ink is applied in areas defined by the light areas. The applied light-reflective ink and light-absorbing ink results in a code which represents a reversal of the dark and light areas defined in the bar code symbology.

  • Patent number: 12171925
    Abstract: A system with container volume tracking includes a pump receiving a line connected to a tracked container, an air sensor to detect air in the line, and a controller coupled to pump and sensor. The controller is configured to monitor pump operation, and determine a volume removed from the container based thereon. If the volume removed is less than a first percentage of a target volume and there is air, continue operation after an air purge. If the volume removed is more than the first percentage and less than a second percentage and if there is air, prompt the user for an input, and continue operation after an air purge if a first input is received or end operation if a second input is received. If the volume removed is more than the second percentage and if there is air, end operation.

  • Patent number: 12168087
    Abstract: Blood from a blood source is drawn into a fluid flow circuit. A mononuclear cell product is separated from the blood, followed by at least a portion of the mononuclear cell product being conveyed into an electroporation device without disconnecting the blood source from the fluid flow circuit. The electroporation device opens pores in a membrane of at least one of the cells of the mononuclear cell product to allow DNA material (which is added to the mononuclear cell product prior to electroporation) to enter and modify the genome of the cell. At least a portion of the modified mononuclear cell product is returned to the blood source. The mononuclear cell product may be washed prior to being conveyed into the electroporation device. The modified mononuclear cell product may be washed after exiting the electroporation device.
