Systems, methods, and devices for providing subcutaneous hydration are disclosed. A system for providing subcutaneous hydration may include an infusion bag including a hydration fluid, a tubing removably connected to the infusion bag, a squeezable bulb at least partially encompassing the tubing for at least one of flushing and priming the tubing, and a deployment device including an integrated needle which provides subcutaneous hydration through the needle. A deployment device for subcutaneous hydration includes a base having a needle aperture, a casing attached to the base, a firing mechanism within the casing for deploying a needle from the casing, and at least one wing attached to the base that includes an actuator that regulates the firing mechanism. A method for providing subcutaneous hydration may include steps necessary to operate the systems and devices for subcutaneous hydration.
