Certain embodiments include an infection indicator and/or a coupling device configured to such that a wound drainage container can rotate in relation to a mounting device. ## Claims ### Claim 1 A wound drainage system comprising: a mounting device configured to couple to a patient; a wound drainage container configured to couple to the mounting device, wherein: the wound drainage container comprises an infection detector; the wound drainage container comprises a first coupling device; the mounting device comprises a first side and a second side; the first side of the mounting device comprises an adhesive; the second side of the mounting device comprises a second coupling device; the first coupling device is configured to couple to the second coupling device such that the wound drainage container can rotate in relation to the mounting device when the first and second coupling devices are coupled together; and a wound dressing; and tubing, wherein the wound dressing is coupled to the wound drainage container via the tubing. ### Claim 2 (depends on 1) The wound drainage system of claim 1 wherein the infection detector is a leukocyte esterase indicator. ### Claim 3 (depends on 1) The wound drainage system of claim 1 wherein: the infection detector is located within the wound drainage container; and the infection detector is visible through the wound drainage container. ### Claim 4 (depends on 3) The wound drainage system of claim 3 wherein: the wound drainage container comprises a transparent portion; and the infection detector is visible through the transparent portion of the wound drainage container. ### Claim 5 (depends on 1) The wound drainage system of claim 1 wherein the wound drainage container comprises volume indicators. ### Claim 6 (depends on 1) The wound drainage system of claim 1 wherein the first coupling device is a button and the second coupling device is an aperture configured to receive the button. ### Claim 7 (depends on 1) The wound drainage system of claim 1 wherein the second coupling device is a button and the first coupling device is an aperture configured to receive the button. ### Claim 8 (depends on 1) The wound drainage system of claim 1 wherein the first coupling device and the second coupling device form a snap mechanism. ### Claim 9 (depends on 3) The wound drainage system of claim 3 wherein the wound drainage container comprises a first port and a second port. ### Claim 10 A method of securing a wound drainage container, the method comprising: coupling the wound drainage container to a mounting device, wherein: the wound drainage container can rotate in relation to the mounting device when the wound drainage container and the mounting device are coupled together; and the wound drainage container comprises a port; the wound drainage container comprises an infection detector; coupling tubing to the port; coupling the tubing to a wound dressing. ### Claim 11 (depends on 10) The method of claim 10 wherein: the mounting device comprises an adhesive; and the mounting device is secured to a surface via the adhesive. ### Claim 12 (depends on 11) The method of claim 11 wherein the surface is an epidermis of a patient. ### Claim 13 (depends on 10) The method of claim 10 wherein the infection detector is a leukocyte esterase indicator. ### Claim 14 (depends on 13) The method of claim 13 wherein the leukocyte esterase indicator is configured to change color when exposed to a fluid with a white blood cell count above a threshold. ### Claim 15 (depends on 14) The method of claim 14 further comprising viewing the leukocyte esterase indicator to determine if the leukocyte esterase indicator has changed color.
