Appl. No.:

5/572503

International Classification:

A61M 2500

US Classification:

128349R

Abstract:

A three-way urinary irrigation valve for use with a catheter is disclosed which is movable from a first position in which long term drainage takes place to a second position in which irrigating liquid can be introduced to a bladder, all while maintaining a closed system. The urinary irrigation valve includes a housing defining a first passage having an inlet leading to a bladder and an outlet leading to a drainage bag, and a second passage angularly disposed relative to the first passage and having an inlet at one end and an opposite closed end. A valve gate disposed in the second passage controls the flow of liquids between the inlet and outlet in the first passage, and between the inlet in the first passage and the second passage. An open-topped cap sealingly engages the housing adjacent the end of the second passage having the inlet. A resilient means normally biases the valve gate into a first position in which the valve gate cooperates with the cap to block flow through the second passage and permit flow between the inlet and outlet.

International Classification:

US Classification:

Abstract:

A system for monitoring utilization of surgical sponges with reference to a surgical procedure. The system features a monitor board with a tally panel. The tally panel is generally planar, has reverse and obverse surfaces, and defines a substantial number of trans-panel deposit sites. Each site has small portions adapted suitably to deform in response to application of modest force. When the panel is in in-service orientation, and as the small portions of one site become deformed, the site is adapted to receive and retain a used sponge in trans-panel deposit. Each deposited sponge in part protrudes from the obverse surface and, against the background thereof, is visually accessible and displayed, for tallying. Stands for the monitor board as well as erectile and foldable-as-erected versions of the board and disposal containers for the a board (with a complement of used sponges) are also disclosed.
