Abstract: A femoral arterial or venous compression device for post-catheterization hemostasis includes a supporting frame (base (1), shaft (2) and arm (4)), and an inflatable unit (carriage (6), bellows (7), disk (8), and pad (9)). The supporting frame is fixed on the human body in line with the incision site in order to bring the pad (9) exactly over and in touch with the latter. The bellows (7) are inflated thus compressing the incision site with the pad (9) for all the time needed to reach complete hemostasis. The pressure on the incision remains constant during the compression period and can be regulated and monitored using a medical sphygmomanometer.
