Achieve better patient comfort and enhance your diagnostic capabilities with HMD’s scalp vein infusion sets. Scalp vein sets, also known as butterfly vein sets or winged infusion sets, are medical devices that are primarily used for venipuncture. These get their name from two plastic wings attached on either side of the needle, resembling a butterfly. The wings enable easy handling and attachment with the skin. Moreover, the needle and the wings are attached to a medical-grade, non-toxic, and non-irritant tube. These scalp butterfly sets allow medical professionals to provide an accurate diagnosis since they reduce the chances of the blood breaking down. Also, they are pretty beneficial for collecting blood from patients with bleeding disorders. HMD provides cutting edge butterfly scalp sets, which meet all international standards for quality. What’s more, we offer various butterfly needle sizes, all under an affordable price tag.
