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.

A pressure transducer mounting device may include a support member and a pressure transducer holder. In use, the support member may attach to a support surface, such as a housing of a power injection device, while the pressure transducer holder is moveably connected to the support member. The pressure transducer holder may expand open to receive one of a plurality of different sized pressure transducers and bias closed to hold a received one of the plurality of different sized pressure transducers. In addition, the pressure transducer holder may move relative to the support member to one of a plurality of different vertically elevated positions. The pressure transducer mounting device may accommodate different pressure transducers, providing a universal mounting device that can adapt to different medical provider preferences and different pressure transducer sourcing options.

A connector cover may be used to protect a connector from exposure to environmental contaminants and physical abuse. In some examples, the connector cover includes a housing defining an opening that is configured to receive a connector positioned on the end of a transmission line. The housing may contain a complementary connector for mating with the transmission line connector. The connector cover may also include first and second doors positioned to cover different portions of the opening. In use, the doors may bias together when the connector is not inserted into the housing so as to keep the opening closed. Upon inserting the connector into the opening, the connector cover doors may move apart in response to the connector physically contacting the doors. This may allow a user to insert the connector into the connector cover without using their hands to touch the doors, which may transfer contaminants.
