摘要： A catheter device is described with a safety needle guard that covers and protects the needle after use of the device. The device includes a semi-tubular needle housing containing a flash chamber with a hollow needle extending from the distal end of the flash chamber. A tubular needle guard concentrically fits and slides within the needle housing. The needle guard has a longitudinal slot through which the mounting base of the flash chamber passes as the guard slides within the housing. The top of the semi-tubular housing is open so that a user may access the top of the tubular needle guard with a finger to urge the needle guard to an extended position from the distal end of the housing and in a surrounding position about the needle. As the needle guard attains its fully extended position about the needle, it locks in place in the needle housing.

摘要： In a first process described a tapered catheter tip is molded by placing a tubular catheter over a mandrel and inserting the mandrel and catheter assembly into a mold having an inner mold surface. The molded catheter with flash is thereafter removed from the mold and the mandrel removed from the catheter. The catheter and flash are inserted into a jig which defines an opening through which the flash extends. The opening is defined by a cutting surface and the flash extends above such cutting surface. A cutter is then moved along the cutting surface in order to severe the flash at precisely the appropriate point along the catheter length to leave a formed trimmed catheter. The catheter is thereafter removed from the jig for further processing.

摘要： A method of fabricating a printed circuit board is disclosed. The method comprises forming a metal substrate having a through-hole pattern. The metal substrate is coated with a dielectric powder having a suitable flow length value to form a dielectric coat on the substrate having a sufficient through-hole edge coverage. The dielectric coated substrate is then treated with a second powder to form a satisfactory topcoat thereon. Electrical circuitry is then formed on the topcoat in conjunction with the through hole pattern.

摘要： A new catheter stick protector is described having a metal flap clip which snaps down into place to prevent return of the needle through the protector device once withdrawn. The device is small and received over the needle to provide an interface between the needle hub and the hub of a catheter like product. A sleeve of hydrophobic or fluid impermeable material is provided and attached at one end to the needle hub and at a second end to the tip protector. The length of the material is selected to hold the tip protector in a position just extending beyond the tip of the needle of a catheter inserter.

摘要： An improved catheter assembly is provided wherein a cannula depends from a catheter body having a first passageway therethrough communicating with the cannula through which an introducer needle may be introduced and removed. The assembly is provided with a second passageway communicating with the cannula through which a fluid may be introduced. A moveable means is provided disposed across the first passageway and moveable from a first position to a second position. The moveable means is provided with a duct passing therethrough, the duct being coaxial with the first passageway when the moveable means are in a first position to allow the introduction of removal of the introducer needle. Thereafter, the moveable means are adapted to be moved into a second position in which the access of the duct is displaced to be non-coaxial with the first passageway, and hence out of communication therewith and with the moveable means in the catheter body cooperating to seal the duct from the first and second passageways.

摘要： The invention generally relates to a needle assembly of the kind having a needle, an elongate blunting device, a shifting member, and a flash chamber. The needle is of the kind that has a needle proximal end, a sharp needle distal end and a needle canula extending therethrough. The elongate blunting device is at least partially located within the needle canula. The elongate blunting device is of the kind that has a blunting device proximal end, a blunting device distal end, and a blunting device blood flow passage therethrough through which blood can flow from the blunting device distal end to the blunting device proximal end. The shifting member can be actuated to move relative to the needle and, upon movement relative to the needle, causes movement to the elongate blunting device from a retracted position wherein the blunting device distal end is retracted into the needle canula so that the sharp needle distal end can penetrate the body, to an extended position wherein the blunting device distal end extends out of the needle canula so as to prevent the sharp needle distal end from penetrating the body. The flash chamber is of the kind that has an internal volume which in communication with the blunting device blood flow passage so that the blood can flow from the blunting device blood flow passage into the internal volume. The flash chamber is at least partially made of a material through which blood can be seen when located in the internal volume.

摘要： Methods for forming a rib on a cannula for cooperation with a safety cover which securably and reliably locks the tip of a cannula in an interior chamber within the safety cover. The cover comprises an elongate body having the interior chamber and an axial through hole which extends along the entire length of the body, through the interior chamber and through which the cannula is slidably received. Displacing elements are positioned within the interior chamber, each of which includes a hole for receiving the cannula therethrough, and which displaces upon retraction of the tip of the cannula, thereby preventing subsequent advancement of the cannula tip. The cannula includes a thickened rib adjacent to the tip, and the safety cover should correspondingly include an annular section in the rear portion thereof. The through hole extending through the rear portion has a diameter which is smaller than the thickened rib of the cannula whereby the cannula tip may not be retracted from the safety cover. The rib is formed by a thermal method in which a sleeve is heated to expand its inside diameter to allow the sleeve to be slid onto the cannula. The sleeve is then cooled to room temperature so that the inside diameter contracts to attach the sleeve to the cannula. In another method, a sleeve is placed on the cannula and crimped at the desired location.
