A medical procedure kit incorporates one or more surgical tools necessary to perform at least part of a medical procedure, along with a container having a quantity of a medical adhesive. Medical adhesives are useful as an alternate or an adjunct to surgical sutures and/or staples in wound closure, as well as for covering and protecting surface wounds such as lacerations, abrasions, burns, stomatitis, sores, minor cuts and scrapes, and other wounds. As such, the inclusion of such an adhesive into a composite medical procedure kit can be of great assistance to a medical doctor or surgeon by providing in single kit form, tools necessary to complete many medical procedures, without having to use multiple procedure kits. The adhesive may be independently sterilized and wrapped from the other surgical tools of the resultant kit, and then associated into kit form, or assembled and sterilized together as a unitary kit. When the adhesive is incompatible with sterilizing procedures of the other components of the kit, the adhesive may be pre-sterilized and protected by a sterilization barrier that shields the adhesive from exposure to the sterilization process used to sterilize other tools of the procedure kit. The adhesive is preferably a 1,1 -disubstituted ethylene monomer, such as an alpha-cyanoacrylate.

A 3D surface wound, injury, and personal protective equipment (PPE) data entry system provides an easily usable graphical user interface through which an examiner can objectively record data relating to surface wounds and injuries sustained by a subject human, as well as PPE used when the wounds/injuries were sustained. The system includes a 3D human model onto which the examiner draws the surface wound(s) and/or damage to the PPE. The subject human's record is stored in a database of similar records.
