The footboard 30 also includes side bumpers 208 and 210 and apertures 212 and 214. The apertures 212 and 214 provide handles to facilitate movement of the bed 10. Illustratively, both the headboard 28 and the footboard 30 are made from a plastic material using a blow molding process. It should be understood, however, that the headboard 28 and footboard 30 may be made from other materials and from other processes, if desired.
Refernng now to Figs. 4, 7, and 9, the controls 70 on the footboard 30 are illustratively coupled through a connector assembly 215 to a bed, or second, controller 217 (Fig. 12) supported by the bed 10. As such, the controller 107 of the footboard 30 is electrically coupled to the controller 217 of the bed 10. The bed controller 217 and other bed electronics are illustratively mounted on the frame 20 of the bed 10 as illustrated in U.S. Patent No. 6,208,250. The connector assembly 215 may also supply power to the power supply module 188.

A first connector alignment apparatus 216 is coupled to the footboard 30 and a second connector alignment apparatus 218 is coupled to the frame 20 of the bed 10.
The support posts 140 and 142 of the footboard 30 are formed to include apertures 220 and 222 which slide over upwardly extending mounting posts 224 and 226 on the frame 20 during installation of the footboard 30 onto the frame 20 in the direction of arrow 228 in Fig. 4. The apertures 220 and 222 defined by the support posts 140 and 142 are configured to mate with the respective mounting posts 224 and 226 such that the footboard 30 may be mounted to the frame 20 in a single orientation. More particularly, the mounting post 224 has a substantially rectangular cross-section to mate with the substantially rectangular cross-section of the aperture 220 of the support post 140. Likewise, the mounting post 226 has a substantially circular cross-section to mate with the substantially circular cross-section of the aperture 222 of the support post 142. The posts 224 and 226 and the apertures 220 and 222 provide initial alignment between the footboard 30 and the frame 20. The first and second connector alignment apparatuses 216 and 218 provide further alignment for male and female electrical connectors 230 and 232, respectively.
The first connector alignment apparatus 216 is configured to support a pair of male electrical connectors 230, while the second connector alignment apparatus 218 is configured to support a pair of female electrical connectors 232. The first connector alignment apparatus 216 further includes a base plate 234 having outwardly extending alignment posts 236 and 238 located at opposite ends.

During installation of the footboard 30 on to the frame 20, initial alignment is provided by posts 224 and 226 on the frame 20 extending into the apertures 220 and 222 formed in the footboard 30. As the footboard 30 moves downwardly over the posts 224 and 226, the posts 236 and 238 on the first connector alignment apparatus 216 enter the apertures 246 and 248 in the second connector alignment apparatus 218.
The tapered surfaces 240 and 242 on the posts 236 and 238 and the ramp portions 250 and 252 of the apertures 246 and 248 facilitate insertion of the posts 236 and 238 into the apertures 246 and 248. As such, the alignment apparatuses provide an electrical connection to the footboard 30 automatically when the footboard 30 is installed on the frame 20. Additional details of the first and second connector alignment apparatuses are disclosed in U.S. Patent No. 6,208,250.
With reference to Figs. 2, 3, 7, and 9-12, air is supplied to the mattress 38 from the interior region 128 of the footboard 30 through an air hose assembly 254.
The air hose assembly 254 provides fluid communication between a footboard interface connection assembly 256 located on a rear wall 257 of the footboard 30, and a mattress interface connection assembly 258, located on the left foot end of the mattress 38. The air hose assembly 254 comprises a plurality of independent air stream supply tubes 260a-g bundled together and nested within an outer tube (Fig. 10). Both ends of the air hose assembly 254 may include an interface coupling 264 so that the air hose assembly 254 may be connected to deliver air from the blower 144 to the mattress 38. Illustratively, the interface couplings 264 on each end of the air hose assembly 254 are identical so that either end of the air hose assembly 254 may be attached to either the footboard interface connection assembly 256 or the mattress interface connection assembly 258.
Refernng further to Figs. 2, 10 and 11, the footboard interface connection assembly 256 and the mattress interface connection assembly 258 are illustratively substantially identical and each include a plurality of male connection members 265a-g. The male connection members 265a-g of the footboard interface connection assembly 256 are coupled to independent air stream supply tubes 266a-g, respectively which in turn are connected to the blower 144 through the first and second control valves 146 and 148 (Fig. 11). The male connection members 265a-g of the mattress interface connection assembly 258 is likewise coupled to independent air stream supply tubes 267a-g, respectively, which in turn are connected to the air mattress 38.
The interface couplings 264 of the air hose assembly 254 illustratively include a plurality of female connection members 268a-g coupled to the supply tubes 260a-g of the air hose assembly 254, respectively. The footboard interface connection assembly 256 and the mattress interface connection assembly 258 sealingly mate with the interface couplings 264 of the air hose assembly 254. More particularly, the male connection members 265a-g are sealingly received within the female connection members 268a-g, thereby providing fluid communication between the interface connection assemblies 256 and 258 and their respective interface couplings 264.
An alignment mechanism 269 ensures proper orientation of the connection assemblies 256 and 258 relative to their respective interface couplings 264.
The alignment mechanism 269 includes a slot 270 formed within a coupling ring 271 of each interface connection assembly 256 and 258, and a pin 272 coupled to each of the interface couplings 264.

Additional details of the air hose assembly 254, including the interface connection assemblies 256, 258 and the interface couplings 264, are provided in U.S.
Patent No. 5,647,079.
Referring further to Figs. 7, 8, and 11, the footboard interface connection assembly 256 is received within a relief member 273 supported by the rear wall of the footboard 30. The relief member 273 includes a housing 274 extending inwardly from the rear wall 257 toward the interior region 128 of the footboard 30.
The housing 274 includes first and second inclined sidewalls 275 and 276 connected to upper and lower walls 277 and 278, thereby defining a relief or recess 279.
A
mounting flange 280 is connected to the rear wall 257 through conventional fasteners, such as bolts 281. The footboard interface connection assembly 256 is supported by an aperture 282 formed within the first inclined wall 275.

Referring now to Figs. 2, 7, and 8, the footboard 30 further includes an instruction receptacle 284 supported by the rear wall 257 of the footboard 30.
The instruction receptacle 284 includes a pair of side walls 286 and 288 coupled to an outer wall 289 and defining an interior region 290. An upper end 291 of the instruction receptacle 284 is open to provide access to the interior region 290. Each of the side walls 286 and 288 includes an arcuate lower portion 292 and 294 which defines a fluid passage 296. The arcuate lower portions 292 and 294 are configured to direct fluids downwardly toward the lower end 298 of the instruction receptacle 284 and out through the fluid passage 296.
A plurality of cards 300 are illustratively received within the interior region 290 of the instruction receptacle 284. The cards 300 may comprise instruction sheets for use by a caregiver positioned adjacent to the footboard 30. A guide member is associated with the cards 300 and is configured to guide the cards 300 in movement from within the interior region 290 through the open upper end 291. The guide member 302 illustratively includes a pair of pins 304 and 306 slidably received within a pair of slots 308 and 310 formed within each of the plurality of cards 300 (Fig. 8).
Operation of the air supply components of the footboard 30 is represented schematically in Fig. 12. Upon activation of the power switch 192, AC power is supplied by the external power source 190 to the AC to DC converter 188.
Desired settings for the air mattress 38 may be entered through controls 70 on the lower inclined control panel 76, which is in communication with the controller 107.
The controller 107 activates the blower 144 and the control valves 146 and 148 as required to maintain desired pressures within the zones 44, 46, 48, 50, 52, and 58 of the air mattress 38.
A conventional blower control 312 provides an interface between the blower 144 and the controller 107. More particularly, the AC to DC converter 188 provides 24V DC to the blower control 312, which is used to generates the necessary stepper signals to run the blower 144. A OV DC to SV DC blower speed signal is supplied to the blower control 312 by the controller 107. When operating in a standard condition, the blower speed signal is approximately 4 V DC.
The blower 144 draws air from the atmosphere through the intake 135 formed in the removable cover 126. The air passes through the inlet filter 166 and into the blower 144 through the intake 168. Air is forced out of the blower 144 through the outlet 181 and then into the manifold 174.

The manifold 174 supplies the pressurized air stream to control valves 146 and 148. More particularly, the air stream enters the manifold 174 through the intake 176 and is then separated to pass through the first outlet 178 and the second outlet 180.
Tubing 182 and 184 directs the separated air streams to the first and second control valves 146 and 148. Each control valve 146 and 148 illustratively comprises three zone proportional valves 314. As the separated air streams pass through the control valves 146 and 148, they are further divided into a total of six independent air streams. The number of proportional valves 314 equals the number of independent air streams to be directed to the mattress 38. As may be appreciated, the number of proportional valves 314 may be varied depending upon the number of separately inflatable air bladders or bags included within the mattress 38.
The pressure of each independent air stream, and therefore air mattress zone 44, 46, 48, 50, 52 and 58, is regulated by the opening and closing of its respective proportional valve 314. Illustratively, the proportional valves 314 automatically adjust in response to a signal received from the controller 107, so that their actual output pressures substantially match desired output pressures. The comparison between actual output pressures and desired output pressures is carned out for each valve by a conventional microprocessor (not shown) within the controller 107.
Actual output pressures are measured using pressure transducers (not shown) located at the proportional valves 314. The desired output pressures are calculated by the microprocessor based upon the inputs received from the controls 70 on the footboard 30. The desired output pressure may be generated by the controller 107 based upon a patient's height and weight.
In addition to monitoring the controls 70 on the footboard 30 and controlling the operation of the proportional valves 314, the controller 107 controls the speed of the blower 144. When the microprocessor of the controller 107 detects that the actual output pressure at a valve 314 is less than the desired output pressure, the controller 107 signals one of the valves 314 to open so that the actual pressure increases. If the pressure in the manifold 174 is insufficient to increase the actual output pressure after the opening of the valve 314, the controller 107 signals the blower control 312 to increase the speed of the blower 144. Then, as the actual output pressure increases, and the desired output pressure is exceeded, the controller 107 decreases the flow of valve 314 and reduces the speed of the blower 144.

When a zone proportional valve 314 is unable to match the desired pressure with the correct amount of air pressure, the controller 186 will send an alarm signal to the alarm 121. The alarm 121 will provide an audible signal which may be temporarily silenced by depressing the alarm silence button 120.
The temperature of air supplied by the blower 144 is monitored by a thermometer, illustratively a thermistor 318. The thermistor 318 is continually monitored by the controller 107 for continuity to ensure that it has not been opened.
As the temperature of the air supplied by the blower 144 rises, the resistance of the thermistor 318 decreases, allowing a voltage signal back to the controller 107 to increase. An alarm condition is activated if the thermistor opens, or if the measured air temperature rises above a predetermined temperature. Illustratively, the predetermined temperature is approximately 150°F (66°C), which is based on providing an air temperature to the mattress 38 below approximately 105°F (41°C) .
During the alarm condition, the controller 107 disables the blower 144, illuminates a "service required" indicator light 96 on the central inclined panel 74, and activate the audible alarm 121.
The independent air streams pass from the proportional valves 314 through a CPR dump valve 316, and then into the air supply tubes 260a-g of the air hose assembly 254. The CPR dump valve 316 is an electronically controlled valve actuable to vent all of the independent air streams to the atmosphere simultaneously while air flow from the manifold 174 is stopped. To engage the CPR feature, a caregiver enters a command on the control panel or activates the CPR button located on the housing 124. This sends a signal to the controller 107 to open the CPR
valve 316 and to stop the flow of air from the manifold 174. The present invention also provides that a manual CPR condition may be accomplished by disconnecting the hose assembly 254 from either the footboard 30, thereby allowing air to escape from the mattress 38. The net result of either manner of operation is the rapid deflation under the weight of the patient of all of the zones 44, 46, 48, 50, 52 and 58 of the mattress 38.
In the illustrated embodiment, the footboard 30 and the blower 144, or other fluid supply, are formed integrally as a single unit. Therefore, it is not required to couple a separate blower housing to the footboard 30 or other part of the bed 10 in order to supply air to the mattress 38. In the present invention, the bed 10 illustrated in U.S. Patent No. 6,208,250 is used with a conventional foam, inner spring or static air mattress. When it is desired to switch the conventional mattress to a dynamic air mattress, the footboard shown in U.S. Patent No. 6,208,250 is removed and replaced with the footboard 30 shown in the present application. This provides an integral blower 144, or other fluid supply, for the mattress 38 supported within the footboard 30 on the bed 10.
Although the blower 144 is illustratively located within the footboard 30, it is understood that the blower 144, or other fluid supply, may be located in an interior region of the headboard 28 or in an interior region of one of the siderails 32 and 34.
The headboard 28, the footboard 30, and the siderails 32 and 34 illustratively provide barriers which extend above the top surface 36 of mattress 38 and which are coupled to the frame 20 or articulating deck 22 of the bed 10. Therefore, the present invention provides a fluid supply, such as blower 144, located within an interior region of a barner coupled to a hospital bed 10.
In an illustrative embodiment of the present invention, the footboard 30 includes access panels or doors 320 configured to cover internal chambers 322.
More particularly, the access doors 320 are pivotally coupled to the front wall 195 of the removable cover 126 utilizing conventional mechanisms, such as hinges (not shown).
Alternatively, the access doors 320 may be supported for sliding movement relative to the front wall 195 for providing access to the internal chambers 322. The interior region 128 of the footboard 30 is configured to provide space for the internal chambers 322 to extend therein.
The chambers 322 are illustratively configured to receive control modules 324. The control modules 324 include electrical connectors and valves (not shown) for providing various types of therapy to a patient supported on the bed 10.
For example, different control modules 324 can be provided for rotation therapy, percussion/vibration therapy, sequential compression therapy, or other type of therapy. Details of the control modules 324 are included in U.S. Patent Nos.
5,715,548 and 6,047,424, and in U.S. Patent Application Serial No. 09/532,592, all of which are assigned to the assignee of the present invention and are expressly incorporated by reference herein. In addition, the doors 320 can provide access to storage chambers 322 for storing other items, such as medical supplies, within the interior region 128 of the footboard 30.

In another illustrative embodiment of the present invention, a compression boot or other compression device (not shown) is stored within interior region 128 of the footboard 30 and is accessible through the door 320 on the footboard 30.
If necessary, a separate compressor (not shown) for the compression device may also be stored in interior region 128 of footboard 30. The compression device is removable from the interior region 128 to provide therapy to the patient supported on the mattress 38.
Although the invention has been described in detail with reference to certain illustrated embodiments, variations and modifications exist within the scope and spirit of the invention as described and as defined in the following claims.
