  • Publication number: 20240016686
    Abstract: A medical cart is provided for use in patient care, the medical cart comprising: a front; a back; sides; four legs which have a distal end, a proximal end and a bore at least partially therebetween terminating in an aperture at the proximal end; an accessory pole releasably retained in the bore; a bracket attached to each leg proximate to the distal end; a caster rotatably attached to each bracket with a caster mount; a lower shelf in engagement with the sides; an upper shelf retained by the sides and an asymmetric handle which defines a gap.

  • Publication number: 20220304759
    Abstract: A medical cart for use in patient care is provided, the medical cart comprising: a front; a back; sides; four legs which have a distal end, a proximal end and a bore at least partially therebetween terminating in an aperture at the proximal end; a spring plunger mounted on each leg for releasably retaining a pole in the bore; a bracket attached to each leg proximate to the distal end; a caster rotatably attached to each bracket; a lower shelf attached to the legs and extending between the legs; a ballast sleeve below the lower shelf for releasably retaining weight plates; and an upper shelf attached to the legs and extending between the legs, the upper shelf including a recess at the front extending towards the back.

  • Patent number: 8887512
    Abstract: A carrier for thermally sensitive items such as medications, biological tissue and the like comprises a cooling chamber for receiving items to be cooled and a thermoelectric heat transfer module using the Peltier effect to cool the chamber. To maximize the time the cooling chamber remains in a cooled state when the heat transfer module is deenergized, a polymer gel is confined in conductive heat transfer relationship with the cooling chamber wall to provide a “volume of cold” surrounding the cooling chamber. The polymer gel releases thermal energy to the cooling chamber as the chamber is cooled to attain essentially the same temperature as the cooling chamber and absorbs thermal energy from the cooling chamber when the heat transfer module is deenergized and the cooling chamber begins to warm. Absent active cooling this release and absorption of thermal energy maximizes the duration of cold temperatures in the cooling chamber.
