MEDICAL CLEANING VALVE

The present invention discloses a medical valve comprising: a valve stem including a lumen, the lumen extending along a longitudinal axis of the valve, wherein a radially outer surface of the valve stem includes a first aperture and a second aperture, wherein the lumen is in fluid communication with the first aperture and the second aperture, and wherein a proximal seal, a one-way seal, and three distal seals are disposed on the outer surface of the valve stem, wherein the first aperture is between the proximal seal and the one-way seal, and wherein the second aperture is between a first of the three distal seals and a second of the three distal seals; and an operation portion, including: a stationary portion; a movable portion which is movable relative to the stationary portion and fixed relative to the valve stem; a cap seal disposed between the stationary portion and the movable portion; and a biasing member; wherein movement of the movable portion in a first direction causes deformation of the biasing member, such that a restorative force of the biasing member urges movement of the movable portion in a second direction opposite the first direction, and wherein a frictional force between the cap seal and one of the stationary portion and the movable portion resists the movement of the movable portion in the second direction.
