The present invention relates to a system for irrigating a wound with wound irrigation fluid and for preventing substantial splashback of the wound irrigation fluid. The system comprises: (i) fluid delivery device for delivering wound irrigation fluid; and (ii) a flexible wound irrigation shield configured such that the shield prevents substantial splashback of the irrigation fluid upon irrigation of a wound. The shield is configured to be disposed, preferably removably, on the fluid delivery device. The flexible shield is substantially conformable to a desired wound area, enabling the practitioner to irrigate awkward, uneven, and hard to reach areas. The shield can be folded into a compact position, then opened into a larger shield. The fluid delivery device comprises (i) a fluid source for providing wound irrigation fluid; and (ii) an adaptor for transmitting fluid from the fluid source to the wound. In one embodiment, the adaptor has a substantially planar face that is substantially coplanar with the plane defined by the shield, thereby preventing patient puncture. The preferred adaptor, preferably a multi-part adaptor, features spray pattern adjustability, removable coupling to the shield, the capacity for removably coupling to a variety of different fluid sources, and a variety of other features and advantages.
