A patient hydration system comprises a bladder, a flexible tube, a safety guard, and a mouthpiece. The bladder can be a generally rectangular-shaped pouch designed to hold liquids. The bladder can have an attachment means whereby a retention member can be used to hang the bladder. The bladder has a port that allows the attachment of the flexible tube. The tube is also connected to the safety guard and mouthpiece. The contents of the bladder flow through the tube and out of the mouthpiece on demand. A keeper clip can be added in proximity to the mouthpiece. The safety guard provides a substantial handle for grasping and maneuvering the system, ensures that the mouthpiece is not inadvertently swallowed by the patient, and protects the mouthpiece from surface contamination if the mouthpiece is placed on a table, plate, etc.
