Definitions
- the present invention relates to a bed, trolley or similar apparatus and more particularly to a bed, trolley or similar apparatus with a profiling support surface. It is known to have beds with profiling surfaces to overcome many of the difficulties ' associated with positioning and mobilisation of patients. Such profiling surfaces can offer many advantages, including reduced risk of injury to staff and patients, increased patient independence, faster recovery from illness and improved cost-effectiveness .
- a number of beds with profiling surfaces are known that provide good upright positioning which usually involves raising the back section and the thigh section of the surface.
- Some beds also provide an "auto contour" control that enables the patient to be positioned in an upright position in one operation. During "auto contour" control, the back and thigh sections are driven simultaneously until they reach their fully raised or fully lowered positions.
- the sections begin from a flat condition then the patient is maintained in a relatively constant position, along the axis of the bed during the profiling of the sections .
- the back section and the thigh section are driven simultaneously until they reach their fully flat end positions.
- the thigh section has less angular travel than the back section, the thigh section reaches the fully flat position much earlier, so that as the back section continues to be lowered the patient is moved along the axis of the bed resulting in shear between the patient's skin and the support surface.
- any reduction of the back section angle using the "auto-contour" control will consequentially reduce the thigh section angle such that the thigh section may reach a flat position whilst the back section is still in a relatively elevated position. Increased shear between the patients skin and the mattress surface results.
- the invention seeks to make improvements.
- a profiling surface for a bed or trolley comprising a frame supporting the surface, the surface having at least a back section and a thigh section, the back and thigh sections pivotally connected to the frame for movement from a horizontal position to a raised position, control means to drive actuators to profile the sections, the control means raising the back and thigh sections simultaneously from a flat position until they reach a substantially equivalent angle, the thigh ' section remaining in that position and the back section continuing to be raised until it reaches its maximum position, and for return of the sections to the flat position, the control means only lowering the back section until it reaches a substantially equivalent position to the thigh section, and then simultaneously lowering both the back and thigh sections to the flat position.
- the patient is held in a relatively constant position during the profiling of the sections thereby reducing the shear between the patient's skin and the support surface.
- any adjustments only result in adjustments to the back section angle, thereby maintaining the position of the patient relative to the axis of the bed.
- this form of control allows the majority of patients to use just the "auto contour" control to alter their position when in a profiled position.
- the actuators driving the back and thigh sections each have limit switches to detect their fully extended condition and their fully retracted condition respectively, the back section actuator further provided with a third integrated limit switch between the two end of travel limit switches, the third limit switch position substantially equating to the fully extended condition of the thigh actuator.
- any adjustment of the profile angle only results in actuation of the back section actuator and not the thigh section actuator.
- the present invention allows a simple "one button" adjustment of the profiled position, without the need for software within the control system, enabling a good profiling action to be attained at a very low cost.
- Figure 1 shows a schematic view of the bed platform in a flat position
- Figure 2 shows a schematic view of the bed platform wherein the raised back section and thigh section position are raised to equal angles
- Figure 3 shows a schematic view of the bed platform where the back section is raised further than in Figure 2.
- a bed 10 consists of a platform 20 comprising a back section 21, seat section 22 and thigh section 23 and foot section 24.
- Normally, electrically operated linear actuators, used for driving the bed sections only have two limit switches, one to detect their fully extended condition and one to detect their fully retracted condition. These switches are used to sense the ends of travel of the actuator and interrupt electrical power to the motors.
- the present invention provides a third integrated limit switch in the back section actuator 41, partway between the two end of travel limit switches. This third limit switch is positioned such that it is activated at the same point as the thigh actuator 42 fully extended condition.
- the actuator controls are configured such that when the sections 21,23,24 are driven from a flat position as shown in Figure 1 using the "auto contour" control, the back 21 and thigh 23 sections are moved simultaneously, until they reach a substantially equivalent angle as shown in Figure 2. The thigh section 23 then remains at that position and the back section 21 continues to be driven by actuator 41 until it reaches its maximum position as shown in Figure 3. If the "auto-contour" control is then used to lower the sections, then only the back section 21 is driven down until it reaches a substantially equivalent position to the thigh section 23 in Figure 2. At this point the thigh section 23 will then begin to drive down simultaneously with the back section 21.
- the arrangement incorporates a third limit switch within the back section actuator 41 in a position that substantially equates to the fully extended condition of the thigh actuator 42.
- the actuator controls are configured such that when the back section actuator 41 is in the zone between this limit switch and its fully extended limit switch, any adjustment of "auto contour" has no effect on the thigh section actuator 42. Thereby, the thigh section 23 remains in its fully raised position until the back section 21 is lowered to a substantially equivalent angle .
