Abstract: Disclosed herein is an apparatus for cooling a sterile liquid for use in cryotherapy, the apparatus comprising: a first chamber (202) adapted to receive a removable container (201) of sterile liquid and a fluid port for receiving a fluid for applying, in use, pressure to a received removable container (201); and a second chamber (203) comprising a cooler; wherein the first chamber (202) is arranged to be in thermal conductivity with the second chamber (203) such that, in use, the contents of the first chamber (202) are cooled by the cooler of the second chamber (203). Advantageously, embodiments provide a system, heat exchanger unit within the system and method for supplying a sterilised working fluid to a catheter system for cryotherapy, the working fluid being supplied at a desired and easily controllable temperature and flow rate.

Abstract: A hydration monitoring system for the collection of data about fluid consumption and hydration levels of athletes during training or practice sessions. The system may also measure and analyze carbohydrate consumption. The system utilizes a hydration bottle containing a fluid and to measures the amount of fluid consumed in a given time interval and wirelessly transmit the measurements; and a scale configured to measure the weight of an athlete and wirelessly transmit the measurements. The system further utilizes a data communications hub configured to receive data comprising the measurements from the hydration bottle and scale and forward the data to a computer; and a computer configured to receive the data from the hub for analysis. The computer analyzes the data and calculates whether the athlete should consume more or less fluid and/or more or less carbohydrates.
