A combined fluid injection and inflation system is disclosed and includes a fluid delivery system including at least one pressurizing device, a fluid path, and a control unit. The fluid path is adapted to connect the pressurizing device to a patient via a catheter including a balloon and inserted in the patient. The control unit is operable to control the fluid delivery system. In operation, the control unit selectively actuates the fluid delivery system to operate in a fluid injection mode or in a balloon inflation mode. In the fluid injection mode the pressurizing device delivers fluid to the fluid path for a fluid injection procedure. In the balloon inflation mode, the pressurizing device delivers fluid to the fluid path for inflating the balloon associated with the catheter. An operator control may be connected to the control unit for controlling the fluid delivery system and may be a handheld device.

Medical fluid injection and inflation system

A pump system selectably controls the temperature, flow rate, flow volume, and flow pressure of a fluid being infused into a patient's body. The pump system includes a cartridge and components that removably connect with a pump housing and corresponding components, providing simple attachment of the cartridge to the pump housing. The pump housing includes a pressure sensor, a bubble detector, and a temperature sensor on a first side of the pump housing, and an engaging actuator and a central controller. The cartridge includes on a first side a heat exchanger, a pressure receptor correspondingly aligned with the pressure sensor, and a detector interface correspondingly aligned with the bubble detector and temperature sensor. Upon aligning the cartridge with the pump housing and actuating the engaging actuator, the pressure receptor communicates with the pressure sensor and the detector interface aligns with the bubble detector and temperature sensor.

An aseptic connector comprises a first member and a second member. The first member preferably includes a resilient septum, and the second member preferably includes a penetrating member. Preferably, the septum is formed from an elastomeric material such as a silicone elastomer. The penetrating member preferably includes an extending penetrating element to penetrate the resilient septum. The aseptic connector further comprises a resilient sealing element that contacts the penetrating member and one of an inner wall of the first member and an inner wall of the second member to create a seal between the penetrating member and one of the inner wall of the first member and the inner wall of the second member. The seal created is suitable to withstand relatively high pressures (for example, those experienced during the injection of contrast media in CT procedures). A fluid delivery system comprising at least a first aseptic connector as described above is also provided.
