  • Patent number: 7201760
    Abstract: Disclosed is a single-use surgical scalpel having two molded plastic elements, and a surgical blade. The first molded plastic element is a housing. The housing has an upper and a lower radiused edge, and ribbed interior wall surfaces. The ribbed interior wall surfaces of the molded plastic housing define a channel for slidable engagement of the second molded plastic element which is referred to as a blade carrier. The channel has one open end through which a surgical blade is extended during use, a slot through the lower radiused edge for slidable engagement of an actuator/locking fin, a single-use indicator window, and a retaining element for engaging a distal end of a leaf spring. The molded plastic blade carrier has a first end adapted for engaging the surgical blade, a second end having a leaf spring to assist in blade retraction, the leaf spring having a proximal and a distal end, and a central portion having the actuator/locking fin and a single-use indicator. A single-mold embodiment is also disclosed.

  • Patent number: 5025206
    Abstract: A unitary combination actuator and indicator flag for an electronic energy meter. The integral actuator and mode indicator is slidable within the bezel of the meter and in the off position is not visible. Sliding the actuator simultaneously moves a camming surface over an axially moveable switch to connect the meter test mode, and slides a visible "TEST" flag over the digital readout window to indicate that the watthour meter is in the test mode. Positive actuation and positioning members are included for both the off and on positions.
