Systems and methods are described for salvaging red blood cells from patients during a surgical procedure. In one general aspect, a system is described for extracting blood from blood-soaked absorbent surgical materials such as surgical sponges, gauze, tape, and the like. The collected blood and flu

대표청구항 ▼

1. An assembly for extracting blood from absorbent material, the assembly comprising; a first basin; anda second basin configured to be housed at least partially within the first basin and further configured to receive the absorbent material, the second basin having perforated walls;wherein the first and second basins are configured to receive a flow of a wash solution and to remove the blood from the absorbent material using a cyclonic flow of the wash solution; andwherein a floor of the second basin comprises a plurality of pins that are oriented at an angle into the direction of the cyclonic flow, the pins being configured to catch on the absorbent material to reduce movement of the absorbent material in the direction of the cyclonic flow. 2. The assembly of claim 1, further comprising: a fluid pump configured to deliver the wash solution present in the first basin into the second basin to generate the cyclonic flow, wherein the fluid pump is configured to deliver the wash solution in a substantially horizontal flow direction relative to the absorbent material so as to create a cyclonic vortex of the wash solution, and wherein the wash solution comprises a heparinized saline solution introduced into the first basin and/or the second basin under pressure. 3. The assembly of claim 1, wherein the first basin comprises a collection bowl positioned below the wash solution surface, wherein the collection bowl is in fluid communication with the fluid pump to allow for recirculation of wash solution, and wherein a fluid output of the fluid pump is directed into a multi-output port assembly. 4. The assembly of claim 1, wherein the second basin includes a cylindrically-shaped pillar configured to assist in creating the cyclonic flow of the wash solution, and further comprising a porous ring adapted for insertion into the second basin and having a central aperture to allow for insertion of the ring over the pillar. 5. The assembly of claim 1, wherein the second basin has one or more channels disposed through a wall thereof, wherein the one or more channels allow for a substantially unidirectional exit flow from the second basin into the first basin, wherein a terminus of the one or more channels is configured with a structure to further reduce the likelihood of blood cells re-entering the second basin. 6. The assembly of claim 1, wherein a floor of the first basin is concave or conically shaped in order to direct blood to an exit port of the first basin, and wherein a flow regulation device is disposed in the exit port to allow a technician to regulate blood flow from the first basin. 7. The assembly of claim 6, further comprising a cell salvage machine in fluid communication with the exit port of the first basin.
