ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a patient support and, more particularly, to a patient support having a patient supporting surface thereon with a drop leaf foot section straddled by a pair of foot rest mechanisms.
BACKGROUND OF THE INVENTION
Patient supports are, of course, very well known in the art. A multitude of styles have been developed over the years to accommodate the needs of the medical profession. One such need relates to the obstetrics and gynecological field of medical practice and, more particularly, to the needs of the physician to access the pelvic region of the patient for examination purposes. Oftentimes the physical construction of the patient support gets in the way of such examinations and the foot supports are not always conveniently available for deployment by the physician.
Accordingly, it is an object of this invention to provide a patient support having a pair of selectively longitudinally deployable foot supports conveniently stored underneath the patient support surface, but yet readily accessible by the physician for deployment and patient use.
It is a further object of the invention to provide a patient support, as aforesaid, wherein the foot supports are each laterally shiftable toward and away from each other to facilitate patient comfort.
It is a further object of the invention to provide a patient support, as aforesaid, wherein the foot supports are sturdy and durable and require a minimum of maintenance.
It is a further object of the invention to provide a patient support, as aforesaid, wherein the foot support includes a foot receiving platform having a surface configured to the bottom surface of a typical patient's foot, the platform being yieldably supported to facilitate flexure of the patient's foot.
It is a further object of the invention to provide a patient support, as aforesaid, which additionally includes an elevating mechanism for raising and lowering the patient support surface relative to a base, the patient support surface having a drop leaf foot section configured to move to a vertically upright position leaving the space between the pair of foot rests open for physician access to the pelvic region of the patient.
It is a further object of the invention to provide a patient support, as aforesaid, wherein the drop leaf foot section includes a mechanism for preventing the foot end of the drop leaf foot section from engaging the floor surface on which the patient support device is supported when the patient surface is lowered with respect to the base.
SUMMARY OF THE INVENTION
The objects and purposes of the invention are met by providing a patient support having a frame with a patient supporting surface thereon and a pair of foot rest mechanisms. Each of the foot rest mechanisms include a bearing housing oriented on the frame with a hollow sleeve being swivelably mounted to the bearing housing and facilitating movement of the hollow sleeve side to side and up and down. The hollow sleeve has a guideway extending therethrough. An elongate rod is slidably received in the guideway and is movable with respect to the hollow sleeve longitudinally between a first retracted position and a second extended position with respect to the patient support surface and is fixable at any position between the first and second positions. A foot support is secured to a first end of the elongate rod. The foot support has a manually engageable section thereon for facilitating the application of a selective manual force thereto for effecting at least one of the longitudinal movement, the side to side movement and the up and down movement of the elongate rod. A locking device is provided and is responsive solely to the weight applied by the patient's foot to the foot support for fixing the position of the elongate rod and, consequently, the foot support thereon relative to the patient support surface.
The objects and purposes of the invention are further met by providing a patient support having a frame with a patient supporting surface thereon. The patient support also includes a base and fluid operated jacks for interconnecting the base and the frame. The fluid operated jacks are configured for raising and lowering the frame relative to the base. A drop leaf foot section is pivotally supported on the frame for movement between a first generally horizontally aligned position and a second vertically aligned position. A cam mechanism is oriented between the drop leaf foot section and the base for pivoting the drop leaf foot section, when in a second position thereof, in response to a vertical downward movement of the frame so as to prevent contact of the drop leaf foot section with a surface upon which the patient support is resting.
The objects and purposes of the invention are further met by providing a foot support having an annular frame, a cross member connected to the annular frame and dividing it into a toe section and a heel section and a foot receiving tray secured to the cross member. The foot receiving tray has a spring steel core encased in a contoured platform which has a heel receiving section and a toe receiving section interconnected by a contoured surface. The spring steel core and the contoured platform are secured to the cross member and configured to flex to accommodate flexure of the patient's foot.
