Abstract: A patient support apparatus comprises a base and a support frame. The patient support apparatus also comprises a lift assembly that operates to lift and lower the support frame relative to the base. The lift assembly comprises lift members that extend and collapse to lift and lower the support frame. A timing link is pivotally connected to one of the lift members and pivotally connected to the base. Guides operate to guide movement of the lift members during operation. In some cases guided bodies coupled to the lift members move passively in the guides. In other embodiments, driven members coupled to the lift members move actively in the guides to cause lifting and lowering of the support frame.

Abstract: A patient support comprising a first structure, a second structure adapted to support the weight of a patient and spaced from the first structure, at least one force sensor mounted to the first structure, and a mounting structure mounting the second structure relative to the sensor, which is adapted to transfer normal forces to the sensor but absorb lateral and/or vibration forces so as not to transfer those forces to the sensor.

Abstract: A compact patient support provides a full range of motion and function while optimizing compactness and achieving an improved “low height” position. Casters joined to the base of the support have a low profile and provide mechanical braking about a swivel axis and a rotational axis of the wheels. The low profile of the casters allows for a more compact base. The lift mechanism includes a lift actuator with the motor mounted on the upper of two stacked X-frames allowing for shorter cables and harnesses and allowing for a more compact folding of the X-frames when the support is in a lowered position thereby reducing bulk and contributing to the overall compactness of the patient support.

Abstract: A medical chair comprising a base having one wheel having a brake; and a manual braking mechanism for selectively actuating the brake at the wheel; and a control system operable to control the brake in response to a signal or lack of signal at the chair. Further, the control system includes an actuator, which is coupled to the manual braking mechanism to move the manual braking mechanism to a braking or unbraking position. For example, the actuator may comprise a solenoid, the solenoid being coupled to the manual braking mechanism.

Abstract: A patient support apparatus includes a base, a litter frame, and an elevation mechanism interconnecting the base to the litter frame and being configured to effect changes in elevation of the litter frame relative to the base. The elevation mechanism includes a pair of hydraulic actuators, each actuator covered by a telescoping shroud. The telescoping shroud is connected to the base and to the litter frame by a number of biased catches. The litter frame includes a pair of laterally spaced and longitudinally extending support rails and a plurality of laterally extending support rails interconnecting the longitudinally extending support rails so that the litter frame has a rectangular configuration. The litter frame includes a thigh section configured to be raised and lowered by use of one of a manually pumped hydraulic actuator or a gas-spring assisted lever actuator.

Abstract: A muzzle loading firearm projectile is disclosed that is composed of a multi diameter, hollow base solid copper bullet, the rear cavity filled with a material of low-density, and a gas pressure seal that separates the bullet from the powder charge. The majority of the bullet shank has a diameter less than the bore diameter of the firearm barrel to allow for ease of loading and alignment of the barrel and bullet axis; a narrow ring of material larger than the barrel bore diameter but less than the groove diameter is located at the junction of the bullet shank and nose profile that centers the bullet in the barrel and positively positions the bullet over the powder charge regardless of orientation of the firearm. The low-density material filling the rear cavity of the bullet acts as an expansion medium when impacted by the rear gas seal during the firing process causing the hollow shank of the bullet to expand and lock into the barrel rifling.

Abstract: A wheeled carriage for supporting a patient includes a patient support with head and foot ends and a wheeled base supported by castered wheels. An auxiliary wheel assembly is secured to the wheeled base and includes a rotatable support shaft with an axis and a drive pin locked in a keyed surface of the support shaft. A wheel stowing spring is located at an end of the rotatable support shaft to continually urge an auxiliary wheel mounted at one end of an auxiliary wheel support bracket to a stowed position. The auxiliary wheel support bracket is rotatably connected to the support shaft at an opposing end and has a stop mounted thereon. An auxiliary wheel support spring continually urges the auxiliary wheel support bracket in a first direction about the axis of the support shaft so that the stop on the auxiliary wheel support bracket engages a stop element integral with the drive pin. This arrangement maintains the support spring in a pretensioned state.
