| 发明名称 | Fluid supply apparatus | ||
| 摘要 | A fluid supply apparatus which supplies fluid to a medical apparatus includes: a pump mechanism including a first pump capable of a suction operation of the fluid after a feeding operation of the fluid, and a second pump capable of a suction operation of the fluid during the feeding operation and a feeding operation of the fluid during the suction operation; a flow path which includes an elastic member and which communicates with the first pump and the second pump and supplies the fluid to the medical apparatus; and a flow path deforming unit which deforms a part of the flow path. The flow path deforming unit starts first deformation of the flow path before the first pump switches from the feeding operation to the suction operation, and completes the first deformation and starts second deformation of the flow path during the feeding operation by the second pump. | ||

| 主权项 | 1. A fluid supply apparatus which supplies fluid to a medical apparatus, comprising: a first pump capable of switching between suction of the fluid and ejection of the fluid; a second pump capable of switching between suction of the fluid and ejection of the fluid; a flow path which communicates with the first pump and the second pump and supplies the fluid to the medical apparatus; and a flow path deforming unit which deforms a part of the flow path; wherein the flow path deforming unit presses the flow path before the first pump switches to the state of sucking the fluid, wherein a speed at which the flow path deforming unit presses the flow path is the fastest when the first pump switches from the state of ejecting the fluid to the state of sucking the fluid. | ||
