Automated systems for powered cots

A cot can include a support frame that extends between a front end and a back end. A front leg and a back leg can be slidingly coupled to the support frame. A front actuator can be coupled to the front leg and slide the front leg to retract and extend the front leg. A back actuator can be coupled to the back leg and slide the back leg to retract and extend the front leg. One or more processors can execute machine readable instructions to receive signals from one or more sensors indicative of the front end of the cot and the front leg. The one or more processors can actuate the back actuator to extend the back leg to raise the back end of the cot, when the front end of the cot is supported by a surface and the front leg is retracted a predetermined amount.

HYDRAULIC VALVE AND SYSTEM
20240082079 · 2024-03-14 ·

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.

Hydraulic circuit for a patient handling apparatus

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.

Techniques For Determining A Pose Of A Patient Transport Apparatus

A patient transport apparatus comprising a support frame, a base, a bracket coupled to the support frame and comprising a channel being non-linear, a frame assembly coupled between the support frame and the base and comprising a slidable member disposed in the channel, the slidable member being moveable between a plurality of different positions in the channel to place the support frame in a plurality of different poses relative to the base. The patient transport apparatus also comprises a sensor configured to detect the slidable member in the channel and produce a reading, as well as a controller coupled to the sensor and configured to receive the reading from the sensor, determine the position of the slidable member in the channel based on the reading, and determine the pose of the support frame relative to the base based on the determined position of the slidable member.

MANUAL RELEASE SYSTEMS FOR AMBULANCE COTS

Embodiments of a cot comprise a support frame, legs coupled to the support frame, at least one hydraulic actuator configured to raise or lower the legs, and a manual release system coupled to the at least one actuator and configured to lower the cot manually at a controlled descent rate. The manual release system comprises a manual actuation component, a manual release valve operable to be opened upon actuation by the manual actuation component, a fluid reservoir operable to receive hydraulic fluid from the at least one actuator upon opening of the manual valve; and a flow regulator configured to control the flow rate of the hydraulic fluid into the fluid reservoir, wherein the release of hydraulic fluid into the fluid reservoir at the controlled flow rate is configured to manually lower the cot at the controlled descent rate.

POWERED AMBULANCE COT WITH AN AUTOMATED COT CONTROL SYSTEM

A powered ambulance cot and methods of raising and lowering the cot as well as loading and unloading the cot are disclosed. The cot includes a support frame and legs, each leg having a wheel. An actuator of an actuation system interconnects the frame and legs, and is configured to effect changes in elevation of the frame relative to the wheel of each of the legs. A control system controls activation of the actuation system, and detects both the actuator at a first location relative to the frame, where the first location is remote from a second location and which situates an end of the actuator that is remote from each wheel closer to the frame, and a presence of a signal requesting a change in elevation of said support frame to thereby cause the legs to move relative to the support frame.
