Hospital bed systems

A system for mechanically assisted repositioning of a bed-ridden patient within a hospital-type bed equipped with a moving mattress pad driven by an electric motor. The mattress pad is formed into a continuous loop disposed over a plurality of support and drive rollers. The system is adaptable to existing hospital beds.

BACKGROUND

This invention relates to providing a system for improved management of weak patients, especially invalid patients and other bed-ridden individuals having limited independent mobility. More particularly, this invention relates to providing a system for assisted and unassisted movement of an individual within a hospital bed.

In general, the care of bed-confined individuals having limited independent mobility is a physically demanding task. Often, the movement of the patient within the bed requires strenuous, often dangerous, lifting of the patient by one or more caregivers. Management of the bariatric patient is especially difficult, often requiring several individuals working together to reposition the patient from a prone to a comfortably inclined position. Furthermore, the inclined individual has a tendency to gradually slide downwardly into an uncomfortable position requiring periodic repositioning, frequently requiring, for heavier patients, the muscles of several caregivers. Therefore, a need exists for easy-to-use, economical, and durable systems providing assistance in repositioning of bed-confined individuals, thus reducing stress imposed on the patients, nurses, caregivers, or anyone providing care to the patient.

OBJECTS AND FEATURES OF THE INVENTION

A primary object and feature of the present invention is to provide a system to overcome the above-described problems.

Another primary object and feature of the present invention is to provide a system for mechanically-assisted repositioning of a bed-confined patient within a hospital-type bed.

It is a further object and feature of the present invention to provide such a system that is retrofitted to existing hospital-type beds.

It is another object and feature of the present invention to provide such a system adaptable for use in nursing homes, hospitals, and private care homes.

A further primary object and feature of the present invention is to provide such a system that is efficient, inexpensive, and handy. Other objects and features of this invention will become apparent with reference to the following descriptions.

Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as intended use, cost, design preference, etc., other fastener arrangements, such as, for example, mechanical snaps, zippers, straps, adhesives, etc., may suffice.

Furthermore, upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as intended use, cost, design preference, etc., other mattress/belt arrangements, such as, for example, making the belt an integral part of the mattress (pad), driving the pad in its loop more directly, etc., may suffice. Preferably, endless belt9(or, under appropriate circumstances, combination pad/belt) is rotationally supporting by drive shaft10and by a free-wheeling bearing shaft27located at the foot and head of hospital bed Q respectively, as shown.

Directing attention to the foot portion A of hospital bed Q,FIG. 1shows a preferred spacer2preferably supporting pillow block1that is preferably mounted to frame D, as shown. Preferably, bearing shaft27comprises a substantially cylindrical-shaped member, as shown. Preferably, bearing shaft27(at least embodying herein at least one second support adapted to support such at least one second loop terminus and at least embodying herein at least one second rolling support) is situated within pillow block1and is held in place by at least one removable retainer, most preferably snap ring26, as shown.

Preferably, the operation of motor assembly15(at least embodying herein at least one motor-driven rotator) is manually controlled from control panel32, as shown (at least embodying herein at least one controller adapted to control the operation of such at least one motor-driven rotator). Operation of motor assembly15preferably initiates rotation of mattress pad25and the linear translation of the upper patient-supporting surface108of mattress pad25, thus moving the patient to a selected resting position. Preferably, motor assembly15is adaptable to initiates rotation of mattress pad25by driving any one of the plurality of rolling support assemblies described herein (at least embodying herein wherein at least one of such at least one first support, such at least one second support, and such at least one third support is adapted to rotatably drive such at least one essentially continuous loop along at least one path extending substantially between the at least one head portion and the at least one foot portion of the at least one hospital-type bed-frame).

Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as intended use, bed design, etc., other operational arrangements, such as, for example, rotating the mattress while the bed is configured in a raised position, adapting the controller to provide limited movement of the mattress when the bed is raised, etc., may suffice.

Attention is now directed toFIG. 3, which displays a plan view of existing hospital bed Q indicated by the reference letters A, B, C, and D, modified to comprise patient positioning unit102in accordance with the teachings of the present invention. Preferably, each of the above-described support rollers are preferably positioned with their individual axes of rotation aligned transversely to the bed length, i.e., substantially parallel with head portion B and foot portion A, as shown.

Preferably, spacer2is adapted to support bearing pillow block1by mounting directly to existing bed frame D with two socket head cap screws6, two washers7and two nuts8, as shown.

FIG. 7is a side view of hospital bed Q comprising patient positioning unit102, adjusted to an inclined position, according to a preferred embodiment of the present invention. Hospital bed system100is especially useful in maneuvering an individual to a position within hospital bed Q that allows the adjusted articulation of frame portions D. It should be noted that preferred embodiments of patient positioning unit102comprise an alternate preferred location of control panel32, drive shaft10, and motor15adjacent foot portion A, as shown. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as intended use, user preference, etc., other controller arrangements, such as, for example, providing multiple control points utilizing multiple controllers, providing automatically actuated controls, wireless remote control apparatus, etc., may suffice.

In preferred operation, an individual200resting on patient-supporting surface108of mattress pad25is repositioned by operating control panel32located at foot portion A, as shown. Preferably, motor15slowly turns drive shaft10that is operationally coupled with endless belt9and mattress pad25. The translational movement of patient-supporting surface108by the rotation of mattress pad25moves the supported individual toward head portion B (or foot portion A as selected) of hospital bed Q.

The fitting of patient positioning unit102to hospital bed Q greatly reduces the physical pulling or tugging to which the bed-ridden individual is typically subjected. In addition, upon reading the teachings of this specification, those of ordinary skill in the art will now appreciate that use of patient positioning unit102greatly reduces the potential for injuries and stress to which the caregiver is otherwise subjected.
