Vascular interface system for automation of hemodynamic monitoring and therapy
Bisera, J.; Weil, M.H.; Carrington, J.H.; Palley, N.; Chaffee, M., 1978: Vascular interface system for automation of hemodynamic monitoring and therapy. Medical and Biological Engineering and Computing 16(3): 278-284
A vascular interface system was designed to relieve the bedside staff in the critical-care environment of time-consuming and unreliable manual operations. A computer-based data acquisition system is linked directly to the patient; automatic hemodynamic monitoring and therapy are provided. The vascular interface system provides access to the patient's vascular sites primarily through pneumatically operated valve assemblies which are biologically (blood) compatible. All connections between catheter and measuring instruments are short, transparent tubes which are easily visible for observation. Operation of the system is simplified through the use of push-button controls with each control assigned a specific procedure (e.g., pressure monitoring, catheter flush and cardiac output). Special safety features built into the system, such as manual override of valve control, ensure continuing operation despite power failure. The existence of the vascular interface system now allows the distribution of blood to a variety of online satellite systems at the bedside. The use of automated equipment frees vital personnel from time-consuming procedures and allows them to return to the real task of observation and patient care.
