Abstract
The present invention provides a device and method for safely applying cyanoacrylate or other adhesives to skin lacerations.
Claims25
A wound approximation device, the device comprising:
- a cyanoacrylate wound-sealing adhesive;
- and
- a solid resilient sheet comprising an opening, wherein the opening is of a sufficient size such that it surrounds a skin wound and exposes a margin of skin surrounding the wound when the resilient sheet in a stretched form is placed against the skin, wherein the resilient sheet is configured to approximate the wound when allowed to relax into an unstretched form when placed against the skin, and wherein a portion of the resilient sheet adjacent to the opening and opposite to a side of the resilient sheet to be placed against the skin is coated with a low surface energy material which does not form a strong bond with a the cured cyanoacrylate wound-sealing adhesive, such when the cyanoacrylate wound-sealing adhesive is applied through the opening to the margin of skin surrounding the approximated wound so as to seal the wound upon curing, the resilient sheet can be removed from against the skin without disturbing the cured cyanoacrylate adhesive sealing the wound.
A method of sealing a wound, the method comprising the steps of:
- providing a wound approximation device, the device comprising a solid resilient sheet comprising an opening, wherein a portion of the resilient sheet adjacent to the opening and opposite to a side of the resilient sheet to be placed against the skin is coated with a low surface energy material which does not form a strong bond with a cured cyanoacrylate adhesive;
- applying tension to the resilient sheet whereby the opening is enlarged to a sufficient size such that it can surround a skin wound and expose a margin of skin surrounding the wound;
- pressing the resilient sheet under tension against the skin to form a bond to the skin, such that the opening surrounds the skin wound and exposes a margin of skin surrounding the wound;
- releasing the tension in the resilient sheet, whereby the wound is approximated;
- applying a cyanoacrylate adhesive through the opening to the margin of skin surrounding the approximated wound;
- allowing the cyanoacrylate adhesive to cure, whereby the wound is sealed;
- and
- removing the resilient sheet from against the skin without disturbing the cured cyanoacrylate adhesive sealing the wound.
