    摘要: A safety syringe for medical use is disclosed as having an injection-molded body with a tubular barrel having a finger flange projecting transversely from the barrel near a proximal end of the barrel and a cylindrical collar projecting rearwardly from the finger flange to the proximal end of the barrel. A plunger assembly includes a plunger handle end cap and an elastomeric plunger seal insertable into the barrel through a rearwardly facing opening in the cylindrical collar to slidably engage the cylindrical inside wall of the barrel. A cylindrical elastomeric bushing is frictionally engaged around an outside wall of the cylindrical collar, and a selectively removable plunger cap frictionally engages the cylindrical elastomeric bushing. A safety syringe may also include a needle safety device.

    摘要: An intravenous catheter introducer for medical use having a body, a frontal attachment that is disposed in transverse sliding engagement with a front part of the body, a hub tube assembly that is releasably supported by the frontal attachment, and a retractable catheter insertion needle and needle holder that are biased rearwardly by a spring offset laterally from the needle axis, whereby lateral repositioning of the body relative to the frontal attachment following vascular insertion moves a needle retraction cavity disposed inside the body into substantial coaxial alignment and causes the needle holder to be retracted into the needle retraction cavity.

    摘要: A medical syringe having a barrel with a substantially cylindrical, longitudinally extending fluid chamber, a needle retraction cavity substantially coextensive in length with the fluid chamber and disposed adjacent and parallel to the fluid chamber, and at least one substantially flat, outwardly facing display area configured to receive and display an array of volumetric measuring indicia in alignment with and proximal to the fluid chamber.
