Description

A hemostatic bandage for applying pressure after the femoral vein catheter is removed

Technical Field

The utility model belongs to the technical field of medical devices, and in particular relates to a hemostatic bandage for applying pressure after a femoral vein catheter is pulled out.

Background technique

Deep vein catheterization is the insertion of a special infusion catheter into the deep vein. Its main purpose is to monitor central venous pressure and adjust the infusion volume by central venous pressure and blood pressure; to provide a central venous infusion access; to treat patients who require long-term intravenous high-nutrient therapy; to treat critically ill patients who need large amounts of infusion to rescue; and to treat patients who need to monitor central venous pressure during major surgery.

Due to the rich blood supply of the femoral vein, bleeding often occurs after the catheter is removed. Therefore, it is particularly important to prevent bleeding after the catheter is removed. In clinical practice, pressure is applied to stop bleeding for 10 to 15 minutes after the catheter is removed, and then auxiliary devices are used to apply pressure to stop bleeding for 6 hours. The most common auxiliary device is a sandbag, but because it is not fixed, it will fall when the patient turns over, goes to the toilet, etc., and cannot fully achieve the effect of applying pressure.

In view of the above problems, the utility model provides a hemostatic bandage for applying pressure after the femoral vein catheter is pulled out.
