Abstract
A containment and disposal system for human bodily fluids includes a bag and a holster that allows a user to quickly and easily remove and replace the bag. The bag includes an envelope having a hollow interior, an opening for receiving the bodily fluids from a catheter via a one-way valve, and hydrophilic material within the bag that rapidly gels bodily fluids in the bag upon contact. Prior to and during gellation, the one-way valve inhibits escape of the bodily fluids. The gellation sequesters the bodily fluids, and the gelled material further facilitates closure of the one-way valve. The hydrophilic material may include a polymer that is activated upon contact with the bodily fluids.
