Abstract
A blood-collection system configured to permit selection of either collection and disposal of shed blood from a patient or collection and processing of shed blood for autologous transfusion back to the patient includes an automated blood-processing machine. The system may also include a blood-collection reservoir, a separation chamber, and a fluid conduit. The blood-collection reservoir may be engageable with the blood-processing machine so that the machine can identify and report the presence of blood in the reservoir. The separation chamber may also be engageable with the blood processing machine. The fluid conduit may be configured to selectively join the reservoir to the separation chamber by a quick-connect coupling.
Claims13
A blood-salvage system comprising:
- a blood-processing machine attached to a reservoir for collecting shed blood, said blood-processing machine configured to receive and operate a centrifuge rotor in a blood separating and return mode, said blood-processing machine also configured to draw blood into the reservoir prior to receiving the centrifuge rotor;
- and
- a disposable-set component comprising:
- said reservoir, wherein the reservoir includes
- a collection port for permitting shed blood to be drawn from a site into the reservoir,
- an outlet port for permitting blood to be drawn from the reservoir via an outlet tube;
- and
- a first quick-connect coupling for connecting the outlet port and outlet tube to the centrifuge rotor, the first quick-connect coupling adapted to connect with a second quick-connect coupling connected to an inlet tube leading to the centrifuge rotor, the first quick-connect coupling preventing air from entering the outlet tube when disconnected from the second quick-connect coupling, the second quick-connect coupling preventing air from entering the inlet tube when disconnected from the first quick-connect coupling,
- wherein the reservoir and the coupling are stored in a separate hermetically sealed package from the centrifuge rotor.

A blood-salvage system comprising:
- a disposable-set component comprising:
- a centrifuge rotor for separating a blood component from other fluids, and
- a first quick-connect coupling for connecting the centrifuge rotor to a collection reservoir via an inlet tube and an outlet tube, the first quick- connect coupling being connected to the inlet tube and adapted to connect with a second quick-connect coupling connected to the outlet tube leading to the collection reservoir, the first quick-connect coupling preventing air from entering the inlet tube when disconnected from the second quick- connect coupling, the second quick-connect coupling preventing air from entering the outlet tube when disconnected from the first quick-connect coupling,
- wherein the centrifuge rotor is stored in a separate hermetically sealed package from the collection reservoir;
- and
- a blood-processing machine configured to receive and operate the centrifuge rotor and also configured to draw blood into the collection reservoir prior to receiving the centrifuge rotor.
3 more elements
A blood-salvage system comprising:
- a disposable set comprising:
- a first disposable-set component having a reservoir for collecting shed blood, the reservoir including a collection port for permitting shed blood to be drawn from a site into the reservoir and an outlet port for permitting blood to be drawn from the reservoir via an outlet tube;
- a second disposable-set component including a centrifuge rotor for separating a blood component from other fluids, the centrifuge rotor having an inlet port and an inlet tube for introducing blood into the centrifuge rotor;
- a first quick-connect coupling connected to the outlet tube;
- a second quick-connect coupling connected to the inlet tube and connectable to the first quick connect coupling to fluidly connect the first fluid disposable set and the second disposable set;
- a first hermetically sealed package;
- a second hermetically sealed package,
- wherein the first quick-connect coupling prevents air from entering the outlet tube when disconnected from the second quick-connect coupling, and the second quick- connect coupling prevents air from entering the inlet tube when disconnected from the first quick-connect coupling, and wherein the centrifuge rotor is stored in the first hermetically sealed package and the collection reservoir is stored in the second hermetically sealed package;
- and
- a blood-processing machine configured to receive and operate the centrifuge rotor and also configured to draw blood into the reservoir prior to receiving the centrifuge rotor.
