  • Publication number: 20210386974
    Abstract: A catheter system to protect against needle stick injuries and environmental contamination from exposure to residual blood. The catheter system may include a catheter assembly, a needle assembly, and a housing. The needle assembly may be coupled to the catheter assembly and include a needle hub and an introducer needle. The housing may be secured within a lumen of the catheter adapter and may include a distal end, a proximal end, and a cavity. The introducer needle may extend through the housing. A safety clip within the cavity may include an elongated arm portion and a barrier feature. The introducer needle may bias the barrier feature outwardly away from a longitudinal axis of the introducer needle. In response to proximal retraction of the introducer needle, the barrier feature may be configured to move toward the longitudinal axis of the needle and shield the sharp distal tip.

  • Patent number: 8968644
    Abstract: A hydrogen storage alloy having the atomic formula AB4.75-5.25. Where A may comprise at least 85 atomic percent Nd and less than 15 atomic percent other rare earth elements and Mg and B may comprise Ni, Co, and at least one element selected from the group consisting of Mn and Al. The atomic percentages of Mn and Al may be governed by the following formulas where Mn and Al are in atomic percent: 1) Mn+1.5 Al?6 atomic percent; and 2) Mn+Al?12 atomic percent. The total percent of Mn and Al may provide the alloy with a 20° C. plateau pressure of between 4 and 25 psi, preferably between 6 and 20 psi. The hydrogen storage alloy allows a nickel metal hydride battery into which it is incorporated to maintain a voltage of at least 1.2 V at a depth of discharge of 90%.
