Abstract: An example device includes a hopper configured to store a plurality of items of a same type; a sorting assembly interconnected with the hopper and configured to extract a single item from the plurality of items, the sorting assembly comprising: a rotatable disk including at least one slot configured to receive the single item; a release aperture configured to allow the single item to be released from the sorting assembly when the disk is rotated to align the at least one slot with the release aperture; and a dispensing assembly configured to receive the single item from the sorting assembly and dispense the single item from the dispensing apparatus.

Abstract: An example bulk material dispensing apparatus includes: a frame; a hopper supported in the frame, the hopper configured to contain a bulk material for dispensing by the dispensing apparatus and having a hopper outlet; a feeding unit interconnected with the hopper outlet, the feeding unit configured to receive the bulk material from the hopper outlet and comprising: a feeding tube; and an auger disposed in the feeding tube, the auger configured to rotate to drive the bulk material received from the hopper outlet to be dispensed from a dispensing outlet; and a controller interconnected with the auger, the controller configured to: receive a dispensing request specifying a quantity of bulk material to dispense; and control the auger to rotate to dispense the quantity of bulk material.

Abstract: An autotransfusion system for collecting blood from a patient and reinfusing the blood back into the patient is disclosed. The system includes a collection unit, a manually operable portable suction evacuator removably connected to the collection unit, and a blood reinfusion bag removably connected to the collection unit. The collection unit includes a collection chamber that is oversized relative to the volume of blood that the unit is intended to contain, and an airflow port located and oriented in the collection chamber to prevent blood from leaking into the port when the collection unit is oriented upright or on its side. When connected to the patient, the collection unit and portable suction evacuator are maintained free of blood by enclosing them within a substantially transparent, flexible envelope. The envelope enables the unit and evacuator to be connected and set-up for proper operation while preventing blood from contacting the outer surfaces of the unit and evacuator.
