Seal Gasket for a Safety catheter for Blood and Methods of producing the same

摘要

The present Invention relates to methods of production of Seal Gaskets for Blood for a Safety Catheter. This catheter Security includes a portion that has a Peak hereNo deslizablemente elongated axially placed in the sameThe Cannula has a First end that protrudes from the Peak portion fixedly connected with a structure of a patient to receive a Blood Chamber and includes a Second end that is extendedFrom an opposite end of the Peak portion for insertion into a patient's Vein; Said method comprises: a) placing a plastic Extruded Hollow Cylindrical Member with a Central HoleThat extends axially through the Peak portion; (b) extend the Cannula through a Hole in the Hollow Cylindrical axial Member,The axial Hole of the Cylindrical Member is dimensioned to receive the Cannula for providing an annular space around the Cannula; (c) providing HEAT to the Cannula to ocasioThe material of the Inner surface of the axial Hole of the Cylindrical member to make Foam and expand radially Inward to fit in with the external Sealing SurfaceThe Cannula; (d) providing reciprocal axial Movement and the Cannula inside the hole of the Cylindrical surface of the FOAMED member to inhibit the Union between the Cannula and the Member cilu00edndriCoAllowing axial displacement of the Cannula to the Peak portion while maintaining contact with the Cylindrical Sealing Member so that it is the way of packingLlo for Blood.
