The market for our Combat IV Pro Set was designed to the specifications that was requested by Special Forces. Our dome is medically approved plastic with ventilation holes to prevent the possibility of bacteria. The grommet snaps onto the IV line, therefore the catheter cannot be dislodged while in transit. Due to the sandy conditions overseas, we designed Combat IV Pro Set with straps that has velcro ends which are attached to the dome. The strap secures the site, won’t slip or slide and can be adjusted to fit the patients needs. Sand tends to stick to tape, with the straps, we don’t have this problem. It comes with two extra securement straps that can be used anywhere on the body or can be used to secure splints.
