Description

Hemostatic pressure bandage comprising an absorbent pad impregnated with a hemostatic ingredient The following embodiments relate to a medical device used to stop bleeding at a puncture site after a cardiovascular interventional procedure through the radial artery, etc., and more specifically, to a hemostatic compression band comprising an absorbent pad impregnated with a hemostatic component, having a rigid fixation structure through multiple Velcro connections and capable of promoting hemostasis based on an absorbent pad impregnated with a hemostatic component. Recently, the transradial approach via the radial artery has become common for the diagnosis and treatment of cardiovascular diseases. In this process, a tubular component called an introducer sheath is inserted into the artery to advance the procedure instrument into the blood vessel. When the procedure is completed, the introducer sheath is removed from the blood vessel, and there is a high risk of immediate and massive bleeding at the sheath puncture site formed where the sheath was removed. Therefore, applying strong yet stable compression to the affected area immediately after sheath removal to induce hemostasis is a critical factor in determining the success of the procedure. Conventionally, air-inflatable bands or mechanical tightening bands were used to compress the sheath puncture site, but they had the following limitations. First, the method of simply tightening the band in a single direction frequently caused the band to rotate or slip when the patient moved their wrist or sweated, resulting in the compression part failing to aim precisely at the sheath puncture site and becoming dislodged, which caused a hematoma. Second, in patients receiving anticoagulants, physical compression alone after sheath removal prolongs the hemostasis time; even when hemostatic pads are used to address this, the entire amount of medication is released early on, resulting in minimal effectiveness in preventing rebleeding or infection in the later stages of hemostasis. Third, the accuracy of the alignment of the compression site varies depending on the skill level of the medical staff, and it was difficult to achieve both 'appropriate pressure' and 'accurate position' simultaneously, as excessive pressure could lead to radial artery occlusion (RAO) or nerve damage, while insufficient pressure could result in persistent bleeding through the sheath opening.
