A subcutaneous infusion set for the subdermal infusion of fluids which includes a housing having an internal chamber within which a uniquely configured infusion cannula is dynamically mounted. The cannula, which is generally spiral shaped, has a body portion that is disposed within the internal chamber and a pierceable portion which extends angularly outwardly from the base of the apparatus. With this construction, when the device is interconnected with a patient, normal movement by the patient will permit the cannula to move dynamically within the internal chamber while the base of the device which is removably affixed to the patient 's skin remains completely stationary.
