Title:
吸引した流体の流量を制御するための装置
Document Type and Number:
Japanese Patent JP2012511957
Kind Code:
A
Abstract:
A flow control device includes a housing having a motor chamber and a pump chamber. The motor chamber has an outlet for communication with a fluid collection device, and an inlet for communication with an aspiration line through which fluids are delivered into the motor chamber. First and second motor rotors are rotatably disposed in a flow path between the inlet and the outlet in the motor chamber, and a drive shaft is coupled to the first motor rotor. The pump chamber has an outlet for infusing fluid to a surgical site, and an inlet through which infusion fluids are delivered into the pump chamber. First and second pump rotors are rotatably disposed in a flow path between the inlet and the outlet in the pump chamber, where the first pump rotor is coupled to the drive shaft. The drive shaft drives the pump rotors at the same speed as the motor rotors, such that any surge in aspiration flow induces a similar surge in infusion flow.
