Abstract
A delivery apparatus for delivering various media, such as medical and/or pharmaceutical media or the like, from a delivery device, such as a syringe, in which the delivery pressure of the medium as it is dispensed from the delivery device is automatically maintained and regulated at a preselected level throughout delivery of the medium from the delivery apparatus. In one embodiment, the skin temperature of the patient is also sensed and the pressure of the medium being administered to the patient is further adjusted in response to the sensed skin temperature.
