  • Patent number: 8048036
    Abstract: A hypodermic needle assembly configured such that the movement of a needle shield into position to block the needle tip occurs as a direct consequence of a longitudinal force applied by insertion of a syringe plunger is provided. The hypodermic needle assembly according to the present invention comprises a needle, a needle hub, and a safety spring clip assembly, the safety spring clip assembly being configured to automatically launch from the needle hub and slide along the needle until the spring clip meets a needle stop at the needle tip, thus preventing the guard from being removed from the needle shaft. A method of using the hypodermic needle assembly according to the present invention is also provided, which includes the method of launching the spring clip with a syringe having multiple advancing mechanisms.

  • Patent number: 6428514
    Abstract: device for administering liquids comprises an administering part (10) and an adhesive plaster (11). The administering part (10) is connected with a cannula stud (30) and an administering line (14) and carries a liquid. For fastening the administering part (10) to the surface of a patient's skin or the surface of an object the adhesive plaster (11) is stuck on the surface. The adhesive plaster (11) is provided with a plug-in pin (38) which is adapted to be inserted into an insertion opening (43) of the filter (10). By placing the filter (10) onto the plug-in pin (38) the administering part (10) is detachably connected with the adhesive plaster (11). If the administering part (10) is a filter with transparent housing the filter membrane is well visible since the latter is not covered by adhesive strips when the filter is fastened to the patient's body.

  • Patent number: 6347711
    Abstract: A filter for medical fluids comprises a hydrophilic membrane (18) dividing the filter into an inlet chamber (20) and an outlet chamber (22). This prevents air from penetrating the outlet chamber (22). The air retained in the inlet chamber (20) is discharged through vent holes (30, 32). Each vent hole (30, 32) is covered with a hydrophobic membrane (34, 36). According to the invention one of the vent holes (30) is provided in a front wall (38) opposite the hydrophilic membrane (18). The other vent hole (32) is provided in a rear wall (46) located opposite the front wall (38) so that the two vent holes (30, 32) point in opposite directions. Owing to this arrangement of the two vent holes (30, 32) one vent hole (30, 32) points upwards irrespective of the filter position. This improves venting of the inlet chamber (20).
