摘要： A novel catheter apparatus for use in delivering an anesthetic agent or other fluid medicament to the portion of subcutaneous tissue through which a catheter device has been inserted into a patient, thereby allowing the catheter device to be retracted without causing pain or discomfort to the patient. The catheter device has an indwelling cannula adapted for insertion through subcutaneous tissue into a patient's body. A helical sheath is formed from an elongate band that is wrapped around the cannula in a helical fashion so as to be capable of being positioned within the subcutaneous tissue once the cannula has been inserted into the body. The helical sheath has formed therein a lumen into which the anesthetic agent or other fluid medicament can be delivered via a hub that is connected to the proximal end of the helical sheath. The helical sheath has formed therein a plurality of delivery holes that form a fluid communication path with the lumen. The delivery holes permit the anesthetic agent or fluid medicament to be delivered to the surrounding subcutaneous tissue.

摘要： A composite panel manufacturing process with interlocking connections. The method includes laying out the first sheet of pre-preg epoxy carbon fiber, upon a polished and released aluminum tool. A second sheet of epoxy fiberglass is laid out over the top side of the first sheet. Rigid structural foam is laid on top of the second sheet of epoxy fiberglass. A third sheet of pre-preg epoxy fiberglass is laid on top of the rigid structural foam. A fourth sheet of pre-preg epoxy carbon is laid on top of the third sheet of pre-preg epoxy fiberglass with heavy resin/top side out to form a plurality of panels. The plurality of panels are cured to form a multilayer panel. Core material is removed along one edge of a first multilayer panel to make a U-shaped channel having a base and parallel flanges. A grooved slot is cut along one edge of the next multilayer panel. The panels are joined at the corner using an adhesive.
