Abstract: Medical devices and methods for controlling the flow of fluid from wounds are disclosed herein. The medical device can have an adhesive pad defining a catheter-receiving opening, a flexible elongate tensioner, and a tensioner retainer. The tensioner retainer is configured to hold the flexible elongate tensioner such that the adhesive pad applies sufficient pressure to a subject's skin to press the subject's tissue toward a catheter when the catheter is positioned in the catheter-receiving opening and the adhesive pad is adhered to the subject's skin.
