DESC:TECHNICAL FIELD
[001] The embodiment herein generally relates to hospital beds, and more particularly, to a modular hospital bed suitable for accommodating one of manual actuator and a motorized actuator for adjusting position of at least one of a back rest section, a leg rest section and overall height of said bed.
BACKGROUND
[002] Medical beds are specialized beds used in hospital and care environments for patients who have short term or long-term disabilities and require assistance to perform their ADLs (activities of daily living). Various medical beds are known wherein a mattress frame is formed in several independently vertically foldable sections. Such beds enable a patient to be moved from a flat reclining position to a variety of other positions, e.g., a partially sitting position. Suitable mechanical adjusting means are conventionally coupled to the foldable sections to enable the various positions to be assumed with no exertion to the patient and with a minimum of effort to a nurse or other attendant. The movement of parts of the bed originally was effected manually by hospital personnel, for example by turning a crank provided on the bed.
[003] Motorized operated hospital beds are conventional in which a head and leg sections of an articulated frame can be adjusted to a desired inclination by one or more motors. In this fashion, a patient's back or legs can be adjusted to a desired inclination. The actuating mechanism for the head section of the articulated mattress frame may include an electric motor which rotates an elongated threaded shaft. A nut is threadably mounted for longitudinal movement along the shaft and is fixed against rotation relative thereto. Thus, rotation of the shaft produces longitudinal travel of the nut. A linkage interconnects the nut and the head section of the articulated frame in such a way as to convert longitudinal motion of the nut into rotational movement of the head section, thereby altering the inclination of the latter. The motor can be deactivated at any time to hold the head section in a given position of adjustment.
[004] However, the existing medical beds have standalone features, i.e. they can either be fully motorized, fully manual or combination of both. Thus, the greatest need arises in converting the basic manually operated bed to a motorized bed so that the manually operated beds can be conveniently power operated. To convert the manual beds to motorized beds, they are required to undergo structural changes (like welding, grinding, finishing & powder coating) for upgradation or functional need which is not possible on-site or in a time and cost-efficient manner. The downtime for modifications requires many days or even weeks.
[005] Therefore, there exists a need for a modular hospital bed suitable for accommodating one of manual actuator and a motorized actuator for adjusting position of at least one of a back rest section, a leg rest section and overall height of said bed. Further, there exists a need for a modular hospital bed which can be easily converted from manual to motorized bed. Furthermore, there exists a need for a modular hospital bed which obviates the aforementioned drawbacks.

OBJECTS
[006] The principal object of the embodiments herein is to provide a modular hospital bed suitable for accommodating one of manual actuator and a motorized actuator for adjusting position of at least one of a back rest section, a leg rest section and overall height of said bed.
