  • Patent number: 11957465
    Abstract: Apparatuses, methods, and systems are disclosed for accelerated ergonomic collection of capillary blood. An apparatus and system include a blood collection module with a proximal portion including a vacuum generation chamber, a distal portion including a blood collection chamber, a concave mid portion including a pressure equalization channel configured to equalize reduced air pressure. The apparatus further includes a sealing surface to stably seal the blood collection module to the skin around a collection site and a slide latch actuated by a lengthwise sliding motion. Also included is a lancet carrier with linearly-arranged lancet strips to puncture rows of blood extraction slits in the collection site. The apparatus also includes an angled transfer port with a low-resistance non-microfluidic blood flow channel to a transfer module, then to a plasma separation module with a multilayer laminate and plasma separation membrane. Methods for accelerated ergonomic collection of capillary blood are disclosed.
    Type: Grant

  • Publication number: 20230332094
    Abstract: A tissue processing system for dissociation of and release of cellular components from adipose tissue to prepare stromal vascular fraction includes a portable tissue processing unit for containing biological material including adipose tissue during enzymatic digestion processing and a digestion drive unit configured to receive the tissue processing unit for rotational processing of the tissue processing unit about an axis of rotation. The unit has an upright orientation and a reclined orientation in which the axis of rotation is at a reclined angle to horizontal relative to the upright orientation. The digestion drive unit is configured to receive and drive rotation of the tissue processing unit in the reclined orientation. Methods for processing biological material including adipose tissue include enzymatically digesting adipose tissue with rotation of a tissue processing unit around an axis of rotation in a reclined orientation.
