  • Patent number: 8348894
    Abstract: A needle assembly is able to collect a sample of biological material in a needle of the assembly. The needle assembly has a safety shield capable of being moved on the needle assembly to cover a sharp end of the needle assembly. The safety shield includes a tubular housing. The shield can be locked in place over the sharp end by a locking mechanism. The assembly further includes a reset member selectively operatively engageable with the locking mechanism for releasing the locking mechanism to permit the tubular housing to be moved away from the sharp end of the needle assembly. The safety shield further includes a resilient membrane including a thin sheet of resilient material the entirety of which extending substantially in a plane extending across the tubular housing.

  • Patent number: 8348537
    Abstract: A medical skin applicator apparatus includes a fluid housing having a fluid chamber for storing a medical agent and an applicator coupled to the housing. The fluid housing has a penetrable wall to permit access to the fluid chamber and release of the medical agent therefrom. The applicator includes an applicator surface for applying the medical agent to a patient. The applicator has a penetrating member adapted to penetrate the penetrable wall of the fluid housing upon achieving a predetermined coupled relation of the fluid housing and the applicator, to thereby permit the medical agent to be dispensed from the fluid chamber and applied to the patient with the applicator surface.

  • Patent number: 8348893
    Abstract: A catheter assembly is disclosed which includes a cannula assembly, a locking clip assembly and a housing. The locking clip assembly includes a locking clip, a collar, and a biasing member. The locking clip has a first leg defining a trigger hole and a second leg defining a binding hole. The collar is positioned to engage the locking clip and the biasing member is positioned to urge the collar into engagement with the locking clip to urge the locking clip from a first orientation to a second orientation. In the second orientation, the binding hole is positioned to bind with the insertion needle to prevent retraction of the insertion needle.

  • Patent number: 8280481
    Abstract: The present disclosure provides electrodes that possess components capable of indicating to an end-user when the electrode is in need of replacement. In embodiments, the electrodes include a hydrogel in combination with a pH indicator which changes its color or opacity upon repeated use of the electrode, thereby indicating an appropriate time for changing or replacing the electrode.

  • Patent number: 8275441
    Abstract: The present disclosure provides electrodes that possess components capable of indicating to an end-user when the electrode is in need of replacement. The electrode includes a substrate and a conductive composition on at least a portion of a surface of the substrate. The conductive composition includes at least one hydrogel and at least one component that precipitates from the hydrogel after repeated use of the electrode, thereby providing an indication to replace the electrode.

  • Patent number: 8260438
    Abstract: An electrode pad packaging system including an electrode pouch, an electrode pad (e.g., a defibrillation electrode pad), a wire and a shell is disclosed. The electrode pad is disposed at least partially within the electrode pouch. The wire extends from the electrode pad and, in a disclosed embodiment, at least a portion of the wire is attached to the shell. The shell is disposed in mechanical cooperation with the electrode pouch (e.g., the shell is secured to a portion of the electrode pouch). The shell includes a valve thereon that is configured to allow air to exit the electrode pouch. The valve may be configured to prevent air from entering the electrode pouch. A method of packaging an electrode pad is also disclosed. The method includes providing an electrode pouch, an electrode pad, a wire and a shell. A valve on the shell allows air to exit the electrode pouch.

  • Patent number: 8197132
    Abstract: An electronic thermometer is configured for selectable predictive modes based upon the same predictive algorithm. A mode selector is adapted for user selection between several modes of operation of the thermometer. Each mode of operation utilizes the same predictive algorithm for estimating the temperature of the subject before the thermometer reaches full equilibrium. Different modes offer users a selection for striking the appropriate balance between response time and precision, based upon user preferences and needs.

  • Patent number: 7691090
    Abstract: Featured is a vascular access device such as an IV catheter device including a housing, a tubular member and a seal member, and a securing mechanism. The housing includes a proximal and distal portion and a chamber that extends between the proximal and distal portions. The tubular member is coupled to the housing distal portion so it is fluidly coupled to the chamber. The seal member is disposed within the chamber and the securing mechanism secures the seal member distal end to the housing proximal portion so the seal member is sealingly and compressibly retained between a chamber proximal end and the securing mechanism. Such a seal member also is constituted so a portion of the seal member moves axially responsive to an axial force applied to the proximal end.
