The invention proposes a technique for implementing bed tilt on infant warmers and incubators. The technique combines two tilt mechanisms to provide a low bed chassis height without giving up tilt range and continuous adjustment. The first mechanism includes using a center pivot bed with a continuous tilt mechanism but the range is limited to typically +/- 7.5 degrees. The second mechanism includes a "quick tilt" mechanism that allows an independent bed mattress platform to be tilted at either end by using a pivoting leg to support end of the bed.
FIELD OF INVENTION
The invention generally relates to infant warmers and incubators and more particularly to a technique for implementing bed tilt on infant warmers and incubators.
BACKGROUND OF THE INVENTION
A bed tilt feature is common on most infant warmers and incubators. Typical range of tilt is 12-15 degrees in both directions. A mechanism for continuous adjustment of the tilt angle is important since it enables an exact angle setting. Also, continuous adjustment of the tilt allows for smooth adjustment of the bed with the baby on it.
A design burden for continuous +/-15 degree bed tilt is that each end of the bed is required to have free space to travel both up and down, assuming the tilt axis is at the center of the bed. FIG. 1 depicts a typical method of bed tilt which allows for continuous +/-15 degree bed tilt.
The requirement for free space for bed tilt increases depth of bed chassis. However, a deeper bed chassis is expensive, limits space under the bed for storage/leg room, and affects elevating base travel limits.
In a conventional technique for example, a tilt mechanism is disclosed for adjusting angle of rest of an infant contained within an infant incubator. The tilt mechanism includes at least one bent rod that underlies the bed on which the infant is positioned. By rotating the bent rod, an offset shaped portion of the rod elevates one end of the infant bed.
Another conventional technique includes an infant incubator tilt mechanism that allows infinite adjustment of the tilt angle of the infant mattress within certain limits. The mechanism includes a bent rod positioned within the infant incubator itself and underlying infant bed. The bent rod has an offset portion that engages a bed lifter. As the bent rod is rotated about an axis, the bent rod moves the bed lifter to raise and/or lower the infant bed.
However, the above mentioned conventional techniques provide a heavy and complex design of bed assembly which is not cost efficient.
It would be desirable to have an efficient technique for implementing bed tilt on infant warmers and incubators and simultaneously allows accurate weighing of infants within the bed.
