The present invention relates in general to hospital beds, and more particularly to a hospital bed which can provide a clearing for egress from the foot end of the bed while providing support for standing and ambulation.
Inpatient falls are a common and devastating complication of hospital care, particularly in elderly patients. Patients attempting to stand on their own often suffer slips, falls and serious injuries such as fractures and head trauma. It has been estimated that 700.000 to 1 million hospitalized patients fall each year, resulting in 250,000 injuries and up to 11,000 deaths. Patients in long-term cure facilities are also at very high risk of falls, with approximately 1.3 million nursing home residents in the United States falling each year. Fall prevention measures such as alarm systems, nonslip socks or floors, sitters for keeping patients within line of sight, and lowering the bed height are all useful aspects of a fall prevention program; nevertheless, fall prevention remains the focus of intensive research efforts.
Patients are often required to sit up in bed prior to transferring to a wheelchair or walker, such as elderly or post-surgical patients. For example, a patient having undergone hip or knee replacement is typically urged to move from the bed to a walker on the same day of their surgical procedure; a typical goal for open heart patients is to be sitting up in a chair on the second day following surgery, and abdominal surgery patients are encouraged to be standing at the bedside the first day after surgery. Indeed, the ability to sit up and stand on one's own is an important component of physical and/or occupational therapy, and often the patient will not be cleared to leave the hospital until they are able to exit the hospital bed unassisted.
While early ambulation is typically a goal for hospitalized patients, it may be a difficult task, since such movements can be painful and may cause dizziness or disorientation. Conventional hospital beds typically provide individualized support to the patient's head, torso, legs, and feet. Also, one or more sections of the bed may be able to be moved or re-oriented relative to another to facilitate patient mobility. Nevertheless, to sit up in a typical, conventional hospital bed, a supine patient must first re-orient their body by rolling to one side. The nurse can assist in raising the head of the bed, if needed, to get the patient's torso upright. The patient must then swing their feet around and drop their legs over the side of the bed, and in order to stand they must move their legs and feet away from the bed to bring their feet into contact with the floor. They must then support themselves on their legs, get balanced, and stand up out of the bed. This process can be painful and challenging, and unfortunately it is still common for patients to fall and injure themselves during the process, which increases the length of their hospital stay.
Hospital bed mechanisms for assistance in early ambulation are well known in the art, and may be electrically, hydraulically, and/or pneumatically operated. Some beds have been designed to assist patients in moving from a supine position to a sitting position and then to a standing position. However, while current hospital beds may provide several advantageous features and have generally performed well for their intended purposes, there remains a need for a hospital bed which can lower the risk of falls and reduce the pain of early ambulation while promoting improved patient mobility and safety.
Accordingly, the present invention provides significant improvements to known hospital beds which can enable patients to move more easily from a supine position to a sitting position, and from the sitting position to a standing position, for the purpose of achieving the standing or walking position in a more efficient and less painful manner.
A first aspect of the invention provides a hospital bed having foot egress, the bed comprising: (a) a frame, the frame including a first lateral rail, a second lateral rail, and a retractable crossbar; and (b) a patient support surface supported by the frame, the support surface including: (i) a back section, (ii) a seat section, and (iii) a foot section, the foot section comprising a first foot panel and a second foot panel, the first foot panel being pivotably connected to the first lateral rail and the second foot panel being pivotably connected to the second lateral rail, wherein the retractable crossbar is reversibly movable along the opposing lateral rails between an extended position in which the crossbar is beneath the foot section and a retracted position in which the crossbar is beneath the seat section, wherein the first foot panel and second foot panel are each upwardly pivotable from a substantially co-planar relationship to a substantially parallel relationship, and wherein a clearing for egress from the bed is exposed when the retractable crossbar is in the retracted position and the first and second foot panels are in the substantially parallel relationship.
A second aspect of the invention provides a hospital bed with foot egress, the bed comprising: a frame including a first lateral rail, a second lateral rail, and a retractable crossbar; and a patient support surface coupled to the frame and including a foot section comprising a first foot panel and a second foot panel, wherein each of the first foot panel and the second foot panel include a grab handle for assistance in standing and ambulation, wherein the retractable crossbar is reversibly movable along the frame from an extended position beneath the foot section to a retracted position beneath the seat section, and wherein the first foot panel and the second foot panel are each upwardly pivotable relative to the seat section and away from one another to expose a clearing for egress from the bed.
A third aspect of the invention provides a hospital bed having foot egress, the bed comprising: a frame, the frame including a retractable crossbar movable along a first lateral rail and a second lateral rail, the lateral rails opposing one another; and a patient support surface supported by the frame, the support surface including a back section, a seat section, a thigh section, and a foot section, the foot section comprising a first foot panel and a second foot panel, the first foot panel being pivotably connected to the first lateral rail and the second foot panel being pivotably connected to the second lateral rail, wherein the retractable crossbar is reversibly movable along the opposing lateral rails between an extended position in which the crossbar is beneath the foot section and a retracted position in which the crossbar is beneath the thigh section, wherein each of the first foot panel and the second foot panel are upwardly pivotable from a substantially co-planar relationship to a substantially parallel relationship when the retractable crossbar is in the retracted position, wherein each of the first foot panel and the second foot panel include a grab handle for assistance in standing and ambulation and are configured to lock into place after being pivoted to the substantially parallel relationship, and wherein a clearing for egress from the bed is exposed when the retractable crossbar is in the retracted position and the first and second foot panels are in the substantially parallel relationship.
The nature and advantages of the present invention will be more fully appreciated from the following drawings, detailed description, and claims.
The accompanying drawings illustrate the prior art and preferred embodiments of the invention and, together with a general description of the invention given above, and the detailed description given below, explain the principles of the invention.
Referring initially to
In contrast, the foot section 17 is typically not pivotably attached to the adjacent seat section 16 (or the thigh section 25, if present), and instead includes a first foot panel 21 and a second foot panel 22, both of which are pivotably mounted on opposing first and second lateral rails 23, 24 at the foot end of the frame 11, with the first foot panel 21 being pivotably connected to the first lateral rail 23 and the second foot panel 22 being pivotably connected to the second lateral rail 24 at the foot end of the frame 11. Each of the foot panels 21, 22 are movable relative to the other, and they are also movable relative to the seat section 16, so that the foot section 17 of the bed can be “opened” as shown in
For the purposes of the present invention, the patient support surface 12 of the hospital bed can include either three or four sections, so long as there is the foot section 17, as described herein. The various sections 15, 16, 17, 25 of the patient support surface 12 can each include conventional molded foam pads or mattresses to provide a suitable soft, yet supportive surface upon which a patient can rest. Likewise, the foot section 17 including the first foot panel 21 and the second foot panel 22, can also be capped or topped with a molded foam pad or mattress. Fitted sheets can cover each of the various support surface sections, and when soiled or dirty they can be easily removed and replaced by the hospital staff.
The inventive hospital bed 10 can be converted between a bed configuration and a chair configuration. When in the bed configuration as shown in
Conversely, when the patient support surface 12 is utilized in a chair configuration, as shown in
In addition to the guard rails 13,
As can be seen from comparing
The undersides of the panels 21, 22 can include integrated heel supports (not shown) which can advantageously allow for comfortable placement and securement of the patient's feet when the panels 21, 22 are in the raised or vertical configuration. i.e. the substantially parallel relationship. Heel supports are known in the art for use as stirrups for exposing the patient's groin area for cleaning, and/or positioning the patient for urinary catheterization, if needed. In addition, heel supports can be useful for comfortably holding the supine patient's feet and maneuvering their legs while moving the foot panels between the open and closed positions. The inclusion of heel supports in the inventive foot panels provides another advantageous use for the present invention, in addition to providing a safe clearing for standing and egress from the bed.
As shown in
The retractable crossbar 20 disclosed herein is reversibly movable along the frame of the bed from an extended position under the foot section of the patient support surface to a retracted position beneath the seat section. Retraction of the crossbar 20 towards the center of the bed frame is necessary prior to or during the upward pivoting of the foot panels, to provide a safe clearing 18 for standing and egress from the foot end of the bed. Otherwise, the patient could easily injure themselves on the crossbar if it were not retracted. The retractable crossbar can be caused to move manually or by electronic-, hydraulic-, or pneumatic-operated means.
Another embodiment of the retracting means (not shown) can be in the form of a linkage system which can be operated by a pair of actuators, for example, small motors which can reversibly move the crossbar inward and outward. Once the linkage system, activated by the small motors, has withdrawn the crossbar towards the center of the bed, the panels can be rotated upward and outward via their connection with the lateral rails from a co-planar position to a substantially parallel relationship to expose the clearing.
For safety purposes, the foot panels of the foot section can typically include a retention mechanism (not shown) which maintains the panels in a “closed”, locked position, in co-planar abutment with each other and with the seat section (or the thigh section, if present), as is seen in the bed configuration. That is, when the foot panels are closed, a safety feature of the bed can include locking of the foot panels into this position and only permitting opening of the panels after the crossbar has been fully withdrawn into its retracted, stored position under the seat section of the bed. Therefore, the pair of foot panels should only be pivotable to reveal the clearing, and only pivotable in an upward direction, after the crossbar has first been fully retracted. As noted above, if the panels are opened before the crossbar has been retracted, then the patient could trip over the crossbar and be injured due to the crossbar blocking the path to egress. Also, it is important for safety reasons that the crossbar be in the fully extended position at the end of the frame when in the bed configuration. This is necessary to provide frame support for the patient's feet when lying supine, as well as support for a visitor who may choose to sit on the end of the bed (e.g. if there are no footboards). Once the crossbar is fully retracted, the foot panels can be upwardly pivoted to a substantially parallel relationship and locked into place to expose the clearing for standing and ambulation. The grab handles of the foot panels can now be accessed by the patient and used for support in standing.
The hospital bed disclosed herein advantageously makes it easier for patients to go from laying to sitting, and from sitting to standing, and also provides an improved manner of ingress and egress. It can be useful not only in the acute post-operative care setting, but also in long-term care facilities, as well as in home health care settings. The clearing created by the bed can be useful for nurses when helping patients such as the fragile, obese, or incontinent to get into and out of the bed, without the risk of falling that is attributable to conventional hospital beds. The clearing created at the foot of the bed can also provide a space to maneuver a scale, a bedside toilet, physical therapy equipment such as a walker, a wheelchair, or a mobile treadmill. Use of a conventional overbed table, also known as a bed table or a tilt top table, is also made much easier and safer. Overbed tables are intended to provide a steady surface while laying in a hospital bed, for example, for a patient to eat on or do office work on. The combination of the inventive bed with an overbed table can allow the patient to safely be seated at the foot of the bed while eating, with their feet safely on the floor, as opposed to having to lay in bed or sit at the side of the bed. For example, an overbed table can be safely loaded and locked in place by the lateral rails within the clearing at the distal foot end of the bed. In addition, when the patient is sitting in the clearing, the conventional guard rails do not need to be lowered to receive the overbed table, as required when the patient is sitting up in a conventional hospital bed. This is advantageous because often the guard rails are not restored to their upright position with convention overbed table use, leading to falls and injuries. Not having to lower the guard rails at all removes this risk.
While the present invention has been illustrated by the description of embodiments and examples thereof, it is not intended to restrict or in any way limit the scope of the appended claims to such details. Additional advantages and modifications will be readily apparent to those skilled in the art. Accordingly, departures may be made from such details without departing from the scope of the invention.
