Abstract: The present disclosure relates to an apparatus for providing access to bone marrow and delivering a quantity of fluid to an intraosseous space. The apparatus may include a driver having a housing and a drive shaft, and a plunger operating and cartridge drive mechanism for releasably retaining a portion of a cartridge assembly having a plunger assembly. A plunger operating assembly may be disposed within a longitudinal bore of the plunger operating and cartridge drive mechanism. The plunger operating assembly may include a plunger barrel having a chamber configured to receive a portion of the plunger assembly of the cartridge assembly. The apparatus may also include a drive housing for transmitting rotational forces from the drive shaft to the cartridge assembly.

Abstract: The present disclosure relates to an apparatus for delivering a quantity of fluid to bone marrow. The apparatus may include a drive housing, a plunger operating assembly, a retractable sleeve, a first spring, a second spring, and a release mechanism. The drive housing may include a first portion configured to engage a driver assembly and a second portion configured to engage a cartridge assembly. The cartridge assembly may a fluid reservoir and a plunger assembly slidably disposed in the fluid reservoir. The cartridge assembly may be engaged with a bone penetrating needle and configured to rotate to insert the bone penetrating needle into the bone marrow. The first release mechanism may release the second spring to move the plunger operating assembly when the cartridge assembly is rotated to insert the bone penetrating needle into the bone marrow and the retractable sleeve is moved to a retracted position.

Abstract: Apparatus for delivering a quantity of fluid to bone marrow of a bone or providing access to remove fluids from a target site is provided. The apparatus may include a driver, a plunger operating and cartridge assembly mechanism, a cartridge assembly having a fluid reservoir and a bone penetrating needle.

Abstract: A rotary pump includes a stator housing and a rotor. The stator housing preferably has an oblong inner surface. The rotor, which is disposed in the stator housing, preferably has a substantially circular outer surface within which a plurality of vane slots are defined. A first chamber is defined between a first half of the oblong inner surface and the outer surface of the rotor. Similarly, a second chamber is defined between a second half of the oblong inner surface, diametrically opposite the first half, and the outer surface of the rotor. Resting within each of the plurality of vane slots is a corresponding sliding vane. A first inlet port and a first outlet port each provide access to the first chamber. Similarly, a second inlet port and a second outlet port each provide access to the second chamber. At least one of the vanes separates each of the first inlet port, the first outlet port, the second inlet port and the second outlet port from one another.
