Abstract:
1. A fluid pump assembly, comprising: a pump support platform supporting a motor; and a pump removably engaged with the pump support platform, the pump pumping working fluid to and from an intravascular catheter, the motor being removably coupled to the pump to provide power to the pump when the pump is engaged with the pump support platform, wherein the pump support platform includes a quick-release locking arm that prevents the pump from being disengaged with the pump support platform unless the locking arm is rotated to release the pump, wherein the pump support platform is formed with a generally cylindrical pump locking bore formed with a first slot, a second slot, and a third slot, each slot terminating in a respective bay, the pump including a housing supporting first, second, and third legs alignable with the respective bays such that the pump can be moved toward the pump support platform until the legs are within their respective bays, the pump being then rotatable by hand until each leg of the pump reaches a respective end of each slot, wherein during installation of the pump on the pump support platform, at least one leg of the pump rides against and then past the quick-release locking arm until the quick-release locking arm clears the leg and snaps under spring bias to a position to prevent the pump from being removed from the pump support platform.
