Proposed are a medical spray head (300) for spraying one or more fluid substances with the use of a compressed gas, a spray device equipped therewith, and a method for using the same. In order to avoid too high a gas pressure, the spray head comprises a pressure relief valve (310) which guides the compressed gas out of the spray head if the gas pressure exceeds a threshold pressure. As a result, the risk of gas embolisms occurring during the use of such a spray head for medical purposes is reduced.
