CONTROLLING FLOW IN A MEDICAL INJECTION SYSTEM |
摘要 |
A valve apparatus for a medical injection system includes a pinching member and at least one spring-loaded anvil. A tubing line of the injection system may be positioned between the pinching member and the anvil, such that when the pinching member is moved into a pinching position adjacent to the anvil, for example, by rotation of a shaft to which the member is coupled, the pinching member compresses the tubing line against the spring-loaded anvil. The pinching member is preferably rotatable about an auxiliary axis, which is eccentric, or offset from a central axis of the shaft. A spring member of the spring-loaded anvil is preferably pre-loaded. In certain applications, the pinching member, when moved into the pinching position, applies a pinching force of greater than approximately 45 pounds, for example, to prevent flow through the tubing line at an injection pressure of up to approximately 1200 psi. |

1. A method for controlling flow in a medical injection system, the system including a pump having an inlet port and an outlet port, the outlet port being coupled to a first tubing line that is adapted to receive therethrough injections of fluid expelled from the pump, and the inlet port being coupled to a second tubing line that extends from a fluid reservoir for filling the pump, and the method comprising:
positioning the first tubing line between a pinching member and a first spring-loaded anvil, and positioning the second tubing line between the pinching member and a second spring-loaded anvil; and moving the pinching member from a first position, at which the pinching member compresses the first tubing line against the first spring-loaded anvil, to a second position, at which the pinching member compresses the second tubing line against the second spring-loaded anvil. |
