摘要： An apparatus for measuring and detecting the pressure in a fluid being injected into a closed system, for instance, fluid being injected into a dilitation catheter, such as a balloon catheter used for the purpose of percutaneous transluminal angioplasty. The apparatus provides a pressure measuring system that includes a housing for releasably and slidably holding the barrel of a syringe used to deliver fluid into the balloon catheter; and a device for measuring and indicating fluid pressure in the syringe barrel, which is also the balloon pressure. The pressure measuring system indirectly measures pressure changes of fluid within the syringe barrel by sensing movement of the barrel as a result of fluid pressure changes. Since a pressure change is sensed by sensing movement of the syringe barrel, the only parts of the system directly contacted by the fluid inflating the balloon are the syringe barrel and syringe plunger. A control device for controlling movement of a piston within the syringe barrel also is provided. The control device makes it possible to slowly or quickly increase or decrease fluid pressure and facilitates maintenance of a desired pressure.

摘要： The present invention provides an injection system and a pump system for use therein for pressurizing a liquid medium for injection into a patient. In general, the pump system comprises a pressurizing unit having at least one chamber. Each chamber has disposed therein a pressurizing mechanism to pressurize liquid medium within the chamber. Preferably, the pressurizing mechanism positively displaces the liquid medium through generally linear motion of the pressurizing mechanism within the chamber. Through reciprocating linear motion of the pressurizing mechanism (for example, a piston), the liquid medium is alternatively drawn into the chamber from a source of liquid medium (for example, a container) and forced out of the chamber under a desired pressure. Each chamber comprises an inlet port and an outlet port. The pump system also preferably comprises an inlet port check valve which allows the liquid medium to flow into the chamber through the inlet port, but substantially prevents the liquid medium from flowing out of the chamber through the inlet port. Likewise, the pump system preferably comprises an outlet port check valve which allows pressurized liquid medium to flow out of the chamber through the outlet port, but substantially prevents the liquid medium from flowing into the chamber through the outlet port. Each inlet port is connected to a source of liquid medium. Each outlet port is connected to a common outlet line or channel leading to the patient.
