Pressure-Measuring Method And Needle System For Hemodialysis

US Patent:

5454374, Oct 3, 1995

Filed:

Jan 17, 1992

Appl. No.:

7/822416

Inventors:

Rodney S. Omachi - San Francisco CA

International Classification:

A61B 500

US Classification:

128673

Abstract:

A method and devices for measuring pressure within blood vessels used for hemodialysis and also for flow of blood into or from such blood vessels during hemodialysis. In one aspect of the method, a currently available hemodialysis set is used. This set comprises a tube (14) attached at one end to a hollow needle (12) and closed at the other end by a cap (19) which covers a proximal connector (18). The method comprises puncturing the blood vessel with the needle (12), measuring the distance to which blood flows under pressure into tube (14), calculating that pressure from that distance, and finally using the hemodialysis set for flow of blood in the performance of hemodialysis. In other aspects of the method, the improved devices of the invention are used. In one embodiment a proximal portion comprising a hollow needle (12), tube (14) with calibrated markings (16) and a proximal connector (18) are attached to a distal portion comprising a male connector (32) with lumen occluded by a hollow needle with a capillary lumen (34) and closed cylinder (24). The improvements in this embodiment increase the length of tube filled by blood and decrease the fluctuation in that length as a result of change in pressure between systole and diastole.
