A pressure solution of an infusion solution holder has a collar that is ergonomically fitted to the shape of the shoulders. The collar includes a pressure tank integrally with the holder and a tank containing the infusion solution. Since the tank containing the infusion solution is located on the patients shoulders and the vertically close to the supply point of the infusion solution, there has to be sufficient pressure in the tank in order for a successful infusion. Therefore, the collars pressure tank is pressurized by the element, whereby the pressure in the pressure tank is pressing the solution tank and creates the necessary pressure at the time of infusion. The pressurization of the pressure tank is shown in the most cost-effective way by pumping with a manual pressure element, such as a ball pump. Pressurization can also be made, for example, by an electric pump.
