US Patent:

43377700, Jul 6, 1982

Filed:

Apr 9, 1981

Appl. No.:

6/252360

Inventors:

James E. Young - Salt Lake City UT
Ralph S. Walker - Highland UT
James R. Chidester - American Fork UT

International Classification:

A61M 500

US Classification:

128214R

Abstract:

A flow regulating device provides continuous, regulated flow of a medical fluid, as well as intermittent, manually controlled larger flows of fluid to a catheter system. Such apparatus includes a control member having an inlet means adapted to be connected by tubing to a source of medical fluid and an outlet means adapted to be connected by tubing to a catheter. A flexible conduit defines at least a portion of a first passage between the inlet means and outlet means of the control member. A cylindrical, hollow extension extends from the outlet means coaxially within and to about the midsection of the flexible conduit. Positioned in the flexible conduit is valve means adapted to open when the conduit is squeezed, thereby providing the larger, intermittent, manually controlled flow of fluid to the catheter system, and to automatically close when the conduit is released. A second passage in the control member connects the inlet and outlet means, and in combination with flow restriction means therein, provides the continuous, regulated flow of fluid to the catheter system.
