    摘要: A device for automatically injecting a material into the body is disclosed. The device includes a drive assembly and a syringe assembly which is mounted to the drive assembly. The drive assembly includes a drive rod, a driver releasably coupled to the drive rod, and a constant force spring which urges the drive rod towards the syringe assembly. The spring first urges the coupled drive rod and driver along the axis of the device, causing the skin to be penetrated by the needle of the syringe assembly. The drive rod is then decoupled from the driver. The spring continues to urge the drive rod in the axial direction, whereby the drive rod engages a piston in the syringe assembly and causes the displacement of the material therein.

    摘要: An anti-infective medical article has chlorhexidine bulk distributed throughout a polyurethane base layer and may have a coating layer on the base layer. The coating layer may be chlorhexidine permeated into the surface or it may be an antibiotic, antithrombogenic agent or a polymeric surface layer laminated onto the base layer. The invention includes a method for preparing the article wherein a homogeneous melt of polymer and chlorhexidine is prepared by twin screw compounding and the melt is extruded to give a medical article having bulk distributed chlorhexidine.

    摘要: An anti-infective medical article has chlorhexidine bulk distributed throughout a polyurethane base layer and may have a coating layer on the base layer. The coating layer may be chlorhexidine, an antibiotic, or an antithrombogenic agent permeated into the surface or it may be a polymeric surface layer having bulk distributed chlorhexidine laminated onto the base layer. The invention includes a method for preparing the article wherein a homogeneous melt of polymer and chlorhexidine is prepared by twin screw compounding and the melt is extruded to give a medical article having bulk distributed chlorhexidine. The article may then be laminated by dipping into a solution of chlorhexidine and a substantially hydrophilic polymer in a solvent.

    摘要: An assembly for mounting medical connector caps includes a carrier formed from a sheet of material and having an array of holes. The assembly also includes a plurality of medical connector caps. Each cap is inserted into one of the holes of the array. The assembly also includes a plurality of sealing tabs. A distinct sealing tab includes a cover portion that sealingly covers the openable end of a corresponding one of the caps and includes an overhang portion that overhangs the openable end thereof. The overhang portion is dimensioned to include a tether of sufficient length that a tip of the tether overlaps an adjacent portion of the carrier. The tip is affixed to the carrier, so that the corresponding one of the caps is tethered to the carrier by such sealing tab.

    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.
