Abstract
Described herein are systems, devices, and methods for methods for autologous blood transfusion. For example, an apparatus may comprise a fluid conduit configured to receive a volume of fluid from a patient and a container fluidically coupled to the fluid conduit. The container may define a reservoir configured to receive the volume of fluid from the fluid conduit. The apparatus may include a vacuum conduit couplable to a vacuum source, a vent configured to vent air into the reservoir, and a filter to filter particulates from the fluid received in the reservoir.

1-10. (canceled)
An apparatus, comprising:
- a container couplable to an aspiration catheter via a fluid path, the container defining a reservoir configured to receive a volume of fluid and clot material from the aspiration catheter;
- a continuous vacuum pump configured to generate a negative pressure within the reservoir at a pressure level that causes the volume of the fluid and the clot material to be drawn into the reservoir via the fluid path while avoiding gases dissolved within the volume of the fluid from separating from the volume of fluid;
- a vent configured to be coupled to the reservoir, the vent configured to vent air into the reservoir to increase the vacuum pressure while avoiding turbulent movement of the volume of fluid within the reservoir;
- and
- an actuator disposed between the aspiration catheter and the container, the actuator configured to control application of the negative pressure to the aspiration catheter to aspirate the volume of fluid and the clot material into the aspiration catheter and through the fluid path into the container.

18-26. (canceled)
An apparatus, comprising:
- a fluid conduit couplable to an aspiration catheter, the fluid conduit configured to receive a volume of fluid and clot material from the aspiration catheter;
- a container including an inlet couplable to the fluid conduit, the container defining a reservoir configured to receive the volume of fluid and the clot material from the fluid conduit;
- a vacuum conduit coupled to the reservoir, the vacuum conduit configured to be coupled to a continuous vacuum pump that, when activated, generates negative pressure within the reservoir to cause the volume of the fluid and the clot material to be drawn into the reservoir, the vacuum conduit further configured to allow air to entire the reservoir to increase the negative pressure at a rate that avoids turbulent movement of the volume of fluid within the reservoir;
- a filter configured to filter the clot material from fluid from the volume of fluid that passes through the filter;
- and
- an outlet port disposed downstream from the filter, the outlet port configured to output the fluid filtered by the filter into a device configured to reinfuse the fluid into the patient.

An apparatus, comprising:
- a fluid conduit couplable to an aspiration catheter, the fluid conduit configured to receive a volume of fluid and clot material from the aspiration catheter;
- container including:
- an inlet disposed at a first end of the container, the being fluidically coupled to the aspiration catheter;
- a reservoir configured to receive, via the inlet, a volume of fluid and the clot material from the aspiration catheter;
- an outlet disposed at a second end of the container opposite the inlet;
- and
- a port separate from the inlet and the outlet;
- a first filter disposed within the reservoir downstream from the inlet, the first filter including openings having a first size and being configured to filter particulates from the clot material having a size greater than the first size;
- and
- a second filter disposed within the reservoir downstream from the first filter and upstream of the outlet, the second filter including openings having a second size and being configured to filter particulates from the plurality of particulates having a size greater than the second size, the second size being smaller than the first size,
- at least one of the outlet and the port couplable to a source of pressure configured to generate a pressure differential to move at least a portion of the volume of fluid within the reservoir toward a point of lower pressure.

An apparatus, comprising:
- a first conduit configured to be coupled to an aspiration catheter disposed in a patient, the first conduit configured to receive a volume of fluid from the patient via the aspiration catheter;
- a container fluidically coupled to the first conduit, the container defining a reservoir configured to receive the volume of fluid from the first conduit;
- a second conduit couplable between the container and a vacuum source, the vacuum source when coupled to the container being configured to generate negative pressure within the reservoir such that the volume of fluid is drawn into the reservoir;
- a flow sensor configured to detect a pressure difference between a first point closer to the aspiration catheter and a second point closer to the vacuum source and to indicate when the pressure difference is greater than a predetermined threshold;
- and
- a vent configured to vent air into the reservoir at an average rate that prevents turbulent movement of the volume of fluid within the reservoir.
