Sharn/Marketlab Disposable Tourniquet Straight Cuffs are single‑use tourniquets designed to assist with venous access during blood collection and other phlebotomy procedures. Manufactured from soft, latex‑free elastic material (often PVC or non‑latex elastomer), these straight cuff tourniquets provide consistent compression to temporarily restrict venous blood flow, enhancing visibility and ease of access for venipuncture.

Their disposable design helps reduce the risk of cross‑contamination and infection, eliminating the need for cleaning or reprocessing. These tourniquets are ideal for use in clinical laboratories, hospitals, physician offices, and outpatient care settings where efficient and hygienic blood draw procedures are needed.
