Scalp vein sets, also called winged infusion sets or butterfly vein sets, are devices used to puncture a vein to administer an injection or perform phlebotomy. This device comprises two bendable appendages, termed “wings,” a hypodermic needle for injection, and a linking mechanism that connects the scalp vein set to another instrument, say a syringe or an extension tube joined to an IV drip. HMD is a manufacturer of cutting-edge scalp vein sets, which offer unparalleled piercing power, and cause minimal pain to the patients. The scalp vein sets are offered in two variants:

  • Non-safety
  • Safety
