A Hemostasis Valve Set is a medical device used during minimally invasive procedures, such as catheterization or endoscopy, to control bleeding and maintain a bloodless field. It consists of a valve housing that is inserted into the incision site, and a removable seal that allows instruments or catheters to be inserted and manipulated while maintaining a closed system.The purpose of the hemostasis valve is to prevent blood loss and maintain the integrity of the procedure. It provides a barrier between the patient's bloodstream and the external environment, reducing the risk of infection.There are different types of hemostasis valve sets available, each with varying features such as single or dual valve systems, removable or integrated seals, and compatibility with different catheter sizes. The choice of hemostasis valve set depends on the specific requirements of the procedure and the preferences of the healthcare provider.
