The base frame 14A supports the upper frame 14B. The upper frame 14B is operable between raised, lowered, and tilted positions relative to the base frame 14A. The upper frame 14B of the patient support apparatus 10 includes a support surface 62, and a support member, such as a mattress 66, which is disposed on the support surface 62 and supported by the upper frame 14B. It is within the scope of the disclosure that the patient support apparatus 10 may be any patient support apparatus 10 known in the art such as, for example, a stretcher, a medical bed, a bed frame, a mattress, other types of beds, surgical tables, examination tables, or any suitable structure for supporting a patient or occupant.
As illustrated in
In various examples, a user interface 88 is coupled to an external side of at least one siderail of the head and foot siderail assemblies 82, 86. The user interface 88 is configured to accept a user input in order to control functions of the mattress 66 or the patient support apparatus 10. Specifically, the user interface 88 receives commands relating to patient comfort or patient care while the patient is positioned on the patient support apparatus 10. It is contemplated that the user interface 88 may be coupled to an internal side of at least one siderail of the head or foot siderail assemblies 82, 86 to allow the patient on the patient support apparatus 10 to control functions of the mattress 66 or the patient support apparatus 10. For example, the patient may call or alert medical professionals or caregivers through the user interface 88. Additionally or alternatively, the user interface 88 may be coupled to the footboard 74 or the headboard 78. It is contemplated that the user interface 88 may be coupled to any suitable component of the patient support apparatus 10 for access by a patient, a caregiver, or other users.

The patient support apparatus 10 generally includes a controller 96 having a processor 98, a memory 100, and other control circuitry. Instructions or routines 102 are stored in the memory 100 and executable by the processor 98. The controller 96 is in communication with various aspects of the patient support apparatus 10 to communicate control signals, including, for example, the MCM system 90 and a motorized unit 104. The motorized unit 104 is operably coupled with a drive system 106 connected with the frame 14. In various aspects, the frame 14 may be operable between raised, lowered, and tilted positions. At least one of the handles 26, 28 can include transport controls 108 for operating the motorized unit 104. The caregiver or other medical professional can input a command through the transport controls 108, which may be communicated to the controller 96. Specifically, the transport controls 108 receive commands relating to braking, speed, direction, or other aspects of transporting the patient support apparatus 10. The transport controls 108 on the handles 26, 28 provide more convenient control during transportation of the patient support apparatus 10. The controller 96 may send a corresponding signal to control the patient support apparatus 10 in response to the command.
With reference still to
An outer edge 112 of the head portion 18 of the frame 14 generally includes the recessed edge 22 configured to provide additional access to a head area of the patient on the patient support apparatus 10. The recessed edge 22 is generally defined in a central area of the head portion 18 of the frame 14. In various examples, the recessed edge 22 is defined between outwardly extending side projections 114, 116 of the frame 14. The side projections 114, 116 extend laterally outwards from the sides of the frame 14, as well as away from the periphery 110 of the mattress 66 to at least partially define a depth of the recessed edge 22. The side projections 114, 116 each define an opening 118, which may be configured to hold or store medical supplies, such as, for example, an oxygen tank.
The recessed edge 22 is generally trapezoidal-shaped. A rear wall 120 of the recessed edge 22 is disposed inboard of the outer edge 112 of the side projections 114, 116. Opposing sidewalls 122, 124 of the recessed edge 22 extend between the rear wall 120 and the outer edge 112 on the side projections 114, 116. The sidewalls 122, 124 extend at oblique angles from the rear wall 120. In the illustrated example, the sidewalls 122, 124 extend at obtuse angles from the rear wall 120, away from one another. Accordingly, a width of the space 24 defined by the recessed edge 22 may be greater further from the mattress 66 relative to proximate the mattress 66 (e.g., adjacent the rear wall 120). It is also contemplated that the recessed edge 22 may define any practicable shape and/or size for providing the caregiver additional access to the occupant on the patient support apparatus 10. The space 24 is wider adjacent to the outer edge 112 on the side projections 114, 116 relative to the width of the space 24 adjacent to the rear wall 120 of the recessed edge 22 may be advantageous for providing comfort to a caregiver moving within the space 24. The opposing sidewalls 122, 124 extending at oblique or obtuse angles may reduce sharp corners where a caregiver moves around to access the patient on the patient support apparatus 10.
Referring to
The bases 126 are pivotally coupled to proximal ends 128 of shafts 130 of the handles 26, 28, respectively. Each handle 26, 28 is operable to rotate or pivot inwardly from the raised position 30 to the lowered position 34. As illustrated in
According to various aspects, a protective cover 132 is disposed proximate the proximal end 128 of each handle 26, 28, which generally covers a mechanical or rotational joint configured to fold, or collapse, the handles 26, 28 from the raised position 30. The protective cover 132 may be configured as polymeric bellows. For example, the handles 26, 28 may fold, or rotate, at a 90° angle. However, the handles 26, 28 may fold to any position between vertical and horizontal. In this way, the handles 26, 28 may be stowed on the head portion 18 of the frame 14. The protective cover 132 may fluidly seal the mechanical joint, such that fluids cannot come into contact with the mechanical joint.
Additional space 24 provided by the recessed edge 22 may not be substantially impinged by the handles 26, 28. The handles 26, 28 rotate inwardly, at least partially toward the mattress 66 and partially toward one another (e.g., the opposing handle). The handles 26, 28 rotate inwardly toward the mattress 66 at an angle (e.g., an inboard angle) a in a range of from about 10° to about 30° relative to a lateral axis a extending between the two handles 26, 28 and parallel to the rear wall 120 of the recessed edge 22. In a non-limiting example, the handles 26, 28 may extend at an angle α of about 19°, extending inboard relative to the frame 14. Once again, the handles 26, 28 do not substantially impinge on the space 24 provided by the recessed edge 22 so that the caregiver has additional space to access the patient on the patient support apparatus 10. In addition, it is understood that when in the raised position 30, each handle 26 affords a substantial width W1 of the space 24 that is equal to or greater than a width W2 of the space 24 defined by the recessed edge 22 of the head portion 18. Accordingly, the caregiver has increased access to the patient on the patient support apparatus 10 when each handle 26, 28 is in the raised position 30 and in the lowered position 34.

The proximal portion 134 of each shaft 130 extends into the connecting portion 138 via a proximal bend 140, and the connecting portion 138 extends into the distal portion 136 via a distal bend 142. The proximal and distal bends 140, 142 of the shafts 130 may be substantially the same shape or define substantially similar angles between adjacent portions of the shafts 130. In the illustrated configuration, each of the proximal and distal bends 140, 142 define an obtuse angle between adjacent portions of the shafts 130. Accordingly, the obtuse angles are defined between the proximal portion 134 and the connecting portion 138, as well as between the connecting portion 138 and the distal portion 136. In this way, each handle 26, 28 generally defines an elongated Z-shape.
The obtuse angle formed by the proximal bend 140 is generally a mirror image of the obtuse angle defined by the distal bend 142. As such, the proximal and distal portions 134, 136 are positioned in the offset, parallel configuration. As illustrated, the proximal and distal bends 140, 142 each have an arcuate shape. However, it is contemplated that the proximal and distal bends 140, 142 may be a variety of shapes, such as, for example, curved, sloped, or the like. It is also contemplated that the proximal and distal bends 140, 142 may not be substantially similar in shape or may not define substantially similar angles. In such examples, the proximal and distal portions 134, 136 may not be substantially parallel.
Referring still to
According to various aspects, a distance between a distal end 146 of each shaft 130 and the connecting portion 138 is less than the distance between the proximal end 128 and the connecting portion 138. Accordingly, the length of the proximal portion 134 is less than the length of the distal portion 136, such that the proximal and distal bends 140, 142 are disposed closer to a grip 154 than the protective cover 132. In this configuration, the proximal portion 134 of each of the shafts 130 extends along the respective sidewall 122, 124, and partially along the rear wall 120. The connecting portion 138 is disposed substantially along or inboard of the rear wall 120 of the recessed edge 22. This configuration also prevents the handles 26, 28 from substantially impinging the space 24 defined by the recessed edge 22 when the handles 26, 28 are in the lowered position 34.
Referring still to
Each grip 154 may be in a fixed position relative to the shaft 130, or alternatively, the grips 154 may be adjustable relative to the shafts 130 to allow the frame 14 to accommodate different user heights. The user or caregiver may grasp the grip 154 at a comfortable position without raising or lowering the handles 26, 28 or the upper frame 14B. The grips 154 may be made of a polymeric, rubber-like material, which may include a thermoplastic elastomer (TPE). In some examples, the grip 154 is made of Santoprene™, which is a thermoplastic vulcanizate (TPV). It may be beneficial for the caregiver to push the handles 26, 28, such that the forearms of the caregiver may be generally parallel with the floor, which may include a position slightly below an elbow. Therefore, caregivers of different heights may benefit from positioning their hands on different locations of the handles 26, 28 or have the grips 154 at different angles in order to form a more ergonomic posture for pushing the patient support apparatus 10. As such, the grips 154 may be positioned on the handles 26, 28 and may be configured to accommodate more than one hand position or grip point.

The IV pole 38 is configured to rotate downward into abutment or close proximity to the head portion 18 of the frame 14. The IV pole 38 includes a support base 162 that is secured to the head portion 18. The support base 162 is pivotally coupled to a proximal end 166 of the IV pole 38. The protective cover 132 (
When in the stowed position 42, the IV pole 38 extends laterally across the support surface 62 of the frame 14 adjacent to, and inboard of, the rear wall 120 of the recessed edge 22. As illustrated, the IV pole 38 is disposed along and aligned with the rear wall 120. Accordingly, the IV pole 38 is disposed substantially over the frame 14. It is contemplated that the IV pole 38 may extend in another direction along the head portion 18 of the frame 14. In this way, the IV pole 38 does not substantially impinge the space 24 defined by the recessed edge 22 when in the stowed position 42 and when in the deployed position 46. As such, the positioning of the IV pole 38 relative to the recessed edge 22 provides increased access to the patient on the patient support apparatus 10.
Referring still to
According to various aspects, both the handles 26, 28 and the IV pole 38 may include a locking feature. The locking feature may retain the handles 26, 28 in the raised position 30 or the lowered position 34 and the IV pole 38 in the stowed position 42 or the deployed position 46. In this way, the handles 26, 28 and the IV pole 38 may not unintentionally move between positions during transportation of the patient support apparatus 10.
The space 24 defined by the recessed edge 22 provides increased access to the patient on the patient support apparatus 10. In addition, the headboard 78 may be removed by the caregiver to further increase access to the patient on the patient support apparatus 10. Stated differently, the headboard 78 may be adjusted between an engaged position 194, as illustrated in

From a top view of the frame 14, the cover 50 substantially obscures the lift arms 206 from view. The sides 220, 222 disposed within the space 24 defined by the recessed edge 22 are vertically aligned with the portions of the lift arms 206 that extend into the space 24. The cover 50 may prevent the caregiver from moving within the space 24 in a way that would cause the caregiver to contact the lift arms 206. The cover 50 may prevent or impede the caregiver from contacting the lift arms 206.
Additionally or alternatively, the proximal portion 134 of the handles 26, 28 may extend at least partially into or through the space 24 defined by the recessed edge 22 when in the lowered position 34 adjacent to the intersections between the sidewalls 122, 124 and the rear wall 120, respectively, as best illustrated in
Referring to
The bumpers 224 generally have a substantially rectangular or trapezoidal shape, however, the bumpers 224 may have any practicable shape that does not substantially interfere with the articulation of the upper and lower joints 210, 214. Sides 226 of the bumpers 224 each define a protrusion 230, such that the shape of the bumpers 224 flares outward at one end. The protrusions 230 may be substantially similar, such that the bumpers 224 are symmetrical. The protrusions 230 are generally positioned over and cover pivoting fasteners of the lift arms 206. As best shown in
Additionally or alternatively, the bumpers 224 define grooves 234 proximate the protrusions 230. The grooves 234 generally accommodate rotation and other movements of the bumpers 224 and the lift arms 206 as the lift arms 206 raise, lower, or tilt the upper frame 14B. The protrusions 230 and the grooves 234 may be advantageous for providing greater flexibility and range of motion to the bumpers 224 to cover the upper or lower joints 210, 214 while the lift arms 206 are in motion or in different positions.
As best illustrated in
Referring to
The bumpers 250, 252 may be coupled to the lift arms 206 via a separate snap feature or other similar fasteners. Each bumper 250, 252 defines apertures 258 for receiving the snap feature. The apertures 258 may each be defined in a recessed portion 260. The recessed portion 260 may be advantageous for accommodating the snap feature. Accordingly, when the bumpers 250, 252 are engaged with the lift arms 206 via the snap features, the snap features are flush with an outer surface of the bumpers 250, 252. The snap feature being flush with the outer surface of the bumpers 250, 252 prevents injurious contact between the snap feature and the caregiver moving in the space 24 defined by the recessed edge 22. Accordingly, if the caregiver contacts the patient support apparatus 10, the caregiver may directly contact the bumpers 250, 252. Each bumper 250, 252 may include any practicable number of apertures 258 and recessed portions 260 for coupling the bumpers 250, 252 to the lift arms 206.
Use of the present disclosure may provide for a variety of advantages. For example, the head portion 18 that includes the recessed edge 22 provides additional or increased access to the patient on the patient support apparatus 10. Additionally, the handles 26, 28 may not substantially impinge with the space 24 defined by the recessed edge 22 when the handles 26, 28 are in the raised or lowered position 30, 34. The shape or rotation of the handles 26, 28 allows the handles 26, 28 to be disposed over the frame 14 when in the lowered position 34 and reduce interference of the handles 26, 28 with the caregiver moving within the space 24 defined by the recessed edge 22. Further, the placement of the IV pole 38 reduces or minimizes interference of the IV pole 38 in the space 24 defined by the recessed edge 22 when the IV pole 38 is in the deployed or stowed position 42, 46. Moreover, the cover 50 coupled to the head portion 18 of the frame 14 extends over the lift arms 206 to reduce direct contact between the caregiver and the lift arms 206. Additionally, the bumpers 224 coupled to the lift arms 206 reduce direct contact between the caregiver and the lift arms 206 or the upper joints 210. Additional benefits or advantages of using this device may also be realized and/or achieved.
