LATERAL SIDE PORTED NEEDLE

摘要

A needle for delivering a fluid to a body includes a shaft having a proximal end, a distal end, and a hollow bore that extends from the proximal end to the distal end. The proximal end is configured to place a fluid reservoir in fluid communication with the hollow bore, and the distal end is configured to penetrate the body. The needle may include at least two groups of side apertures in the shaft, each group of side apertures including at least two laterally aligned side apertures to provide fluid communication between the hollow bore and an exterior of the shaft. Alternatively, the needle may include at least one group of laterally aligned side apertures, the laterally aligned side apertures being positioned at least about 4.5 mm from the proximal end of the needle to permit sub-dermal delivery of fluid.
