    摘要: A patient support apparatus supports a patient and includes a litter. A base is disposed below the litter. A lift mechanism is configured to move the litter and the base relative to one another between extended and collapsed positions. The lift mechanism includes first and second frame assemblies each including an outer frame member and an inner frame member arranged to move within the outer frame member. First and second rollers and first and second slide members are disposed between the outer and inner frame members. The first and second rollers are arranged to roll along at least one of the outer and inner frame members with a load exerted on the lift mechanism from the litter. The first and second slide members are arranged to slide along at least one of the outer and inner frame members with a load exerted on the lift mechanism from the base.

    摘要: A patient handling apparatus includes a patient support surface, a base, and a hydraulic circuit. The hydraulic circuit includes a pump, a fluid reservoir, and a hydraulic cylinder operable to selectively raise or lower the patient support surface or the base. The hydraulic circuit controls flow of fluid between the cylinder and the fluid reservoir to thereby control the movement of the base or patient support surface. In addition, the hydraulic circuit may include a manual bypass circuit configured to bypass the pump in response to a manual input, which allows manual extension or retraction of the cylinder, for example, when the pump is not operational. The hydraulic circuit may also include a pump bypass circuit configured to bypass the pump to allow fluid to discharge from the cap end to the fluid reservoir for faster evacuation of fluid from the cylinder, thereby increasing retraction speed of the rod.

    摘要: An apparatus includes a hydraulic circuit that is configured to selectively open fluid communication between one portion of the hydraulic circuit and another portion of the hydraulic circuit, such as a reservoir, based on the flow of the hydraulic fluid in the one portion. When the flow of hydraulic fluid exceeds a selected threshold in the one portion of the hydraulic circuit, the flow of fluid urges the opening of a hydraulic component of the hydraulic circuit to allow fluid communication between the one portion and the reservoir to discharge fluid from the one portion.
