  • Patent number: 8713730
    Abstract: Embodiments of the invention are directed to medical transport devices, more particularly, to spineboards. In one embodiment, a spineboard includes an upper panel assembly joined to a lower panel assembly by one or more latch assemblies and one or more hinge assemblies. An upper moveable belt wrap about the upper panel assembly and is driven by a motorized drive roller while a lower moveable belt is wrapped about the lower panel assembly and driven by a separate motorized drive roller. The upper and lower moveable belts counter-rotate relative to one another. The upper moveable belt is used to load and unload an injured person from the spineboard while the lower moveable belt is used to advance the spineboard toward and away from the injured person.

  • Patent number: 7938800
    Abstract: A needleshield assembly including an extensible frame, an actuator, a needle and a dispensing device attachment member is disclosed. The extensible frame is capable of moving from a collapsed position to an extended position upon pressure applied to the actuator. In the extended position, the extensible frame both protects the distal end of a needle and renders the needle immobile.

  • Patent number: 6015397
    Abstract: A needle point cover assembly for securely covering and protecting the needle point after a syringe has been used includes a cover in the form of an elongated hollow member that is open at one end for receiving the needle therein, and at its other end is mostly enclosed by an end wall having a hole through which the needle can pass. A lid encloses the otherwise open end of the cover member. The lid has a hole through which the needle may pass so that the needle may extend through both the lid hole and the hole in the end wall. When the syringe is being used to make an injection, the needle point projects through the hole in the end wall. After an injection has been made and the syringe is ready for disposal, a manually actuable extensible frame slides the cover to where its end wall is beyond the extremity of the needle point.
