  • hypodermic needles are commonly used to percutaneously deliver drugs into the body.
  • hypodermic needles may be used to withdraw a substance from the body.
  • hypodermic are commonly used to take a blood sample from a vein in venipuncture.
  • Most conventional hypodermic needles are made from a stainless- steel tube drawn through progressively smaller dies.

Since needle 10 includes a mechanism for transferring thermal energy between two substances (e.g. , the temperature transfer fluid and tubular members 120, 130), needle 10 may be described as comprising a heat exchanger. It should be appreciated that the tortuous path defined by midsection 145c increases the contact surface area between tubular members 120, 130 and the temperature transfer fluid, thereby offering the potential to enhance the heat transfer therebetween.
