A bleed back control assembly for controlling blood loss during catheterization procedures includes a side arm body having a proximal end engaging and retaining a cap assembly and a seal assembly. The seal assembly includes a single elastomeric bleed back seal. The bleed back seal has an aperture and is normally closed. The bleed back seal self-sizes to devices introduced through the aperture. The cap assembly includes a funnel cap having a dilator. Depressing the funnel cap causes the dilator to open the aperture in the bleed back seal. A spring, wound around the dilator, biases the funnel cap to its original position. The side arm body includes a secondary branch having a lumen, and a finger rest on the exterior of the secondary branch.

Bleed back control assembly

A bleed back control assembly and method-for controlling blood loss during catheterization procedures includes a side arm body connected at the proximal end to a seal body. The side arm body comprises one or more branches, each having a lumen, and a finger rest on the exterior of at least one branch. The seal body comprises a cap assembly and a seal assembly. The seal assembly comprises a clamp seal and a bleed back seal, both made of elastomer and held by a seal holder. The cap assembly comprises a threaded cap and a funnel cap. The threaded cap is connected to the seal holder. Rotation of the threaded cap causes the clamp seal to open or close. The funnel cap comprises a dilator, and pressing the funnel cap causes the dilator to open an aperture in the bleed back control seal.

The threaded cap is connected to the seal holder. Rotation of the threaded cap causes the clamp seal to open or close. The funnel cap comprises a dilator, and pressing the funnel cap causes the dilator to open an aperture in the bleed back control seal. A spring, wound around the dilator, returns the funnel cap to its original position, thus closing the bleed back seal. The bleed back seal self-sizes to devices introduced through its aperture. Dilating the bleed back control seal also allows purging of gases or fluids. The clamp seal can clamp a device introduced transluminally to maintain device position, and the clamp seal may also be closed to allow high pressure injections.

An automated engagement system for coupling the plunger of a syringe to a drive arm is provided. A pressure integrity test of the syringe assembly is automatically conducted after engagement. After a position sensor communicates a signal indicating the presence of a properly installed syringe assembly to a processor, a display prompts the operator to vent and then close a stopcock in the fluid line. The processor then controls the drive arm of the system to move into engagement with the plunger of the syringe assembly, and to move the plunger forward into the syringe barrel. The drive arm stops when a pressure sensor produces a signal indicating a positive pressure in the fluid line. The processor then controls the drive arm to move the plunger in a reverse direction until a negative pressure is detected. After this confirmation of pressure integrity in the syringe assembly, the processor controls the drive to move forward until a non-negative pressure is detected by the pressure sensor.
