Abstract
A ventilator headboard apparatus is a modular air handling and filtration device used to recirculate and filter a volume of air. A chassis supports at least one mounting panel, a supply plenum, and a cover plate to manage the atmosphere at the head of a patient's bed, i.e., at the headboard. A plenum space is formed between the supply plenum and the cover plate, across the mounting panel. A pressurized conduit is connected between the supply plenum and an air handling unit, arranging the air handling unit in fluid communication with the plenum space directly, and the atmosphere around a patient's head by extension. With operating energy supplied by a power supply, the air handling unit is used to operably intake or exhaust air across the cover plate according to user configurations and situational requirements.

In a preferred embodiment of the present invention thechassis 10 constitutes a structural element supporting thesupply plenum 33, thecover plate 35, the pressurizedconduit 19, the air handling assembly 27, and thepower supply 17. Thechassis 10 enables an instance of the present invention to be deployed as a modular attachment or modification to existing beds or gurneys, without permanently bonding thechassis 10 to any external structure. In another embodiment, thechassis 10 constitutes a headboard of a conventional bedframe as shown inFIG. 1 . Further, thechassis 10 may be configured to contain and enclose the remaining components, presenting the present invention as a self-contained unit suitable for directly replacing the headboard of an existing bed. - In reference to
FIG. 5 thesupply plenum 33 is mounted to the at least one mounting panel 37 adjacent to therear end 12 of thechassis 10. Thecover plate 35 is mounted to the at least one mounting panel 37 adjacent to thefore end 11 of thechassis 10. This layered arrangement enables thesupply plenum 33 to be mounted onto the at least one mounting panel 37 prior to installation onto thechassis 10. As shown inFIG. 2 the at least one mounting panel 37 is exposed towards thefore end 11 of thechassis 10 prior to the attachment of thecover plate 35, thereby enabling an installer to affix the at least one mounting panel 37 to thechassis 10 as previously outlined. - In at least one embodiment of the present invention the at least one mounting panel 37 is directly engaged to the
chassis 10; thecover plate 35 and thesupply plenum 33 are connected to thechassis 10 through the at least one mounting panel 37 by proxy. This configuration enables thesupply plenum 33 and thecover plate 35 to be standardized in construction, whereas the construction of the at least one mounting panel 37 may be altered to correspond to various extant furniture or external support structures. More specifically, the at least one mounting panel 37 is constructed to mount universally to any external structures to employ said external structures as thechassis 10 in an embodiment of present invention. - The plenum space 21 is delineated between the
supply plenum 33 and thecover plate 35, traversing the at least one mounting panel 37.

In one instance, the air handling assembly 27 is configured to positively pressurize the plenum space 21 via the pressurizedconduit 19. Accordingly, this will expel volumes of air out of thecover plate 35 to constantly refresh and recirculate clean air around a patient's head. In reverse, the air handling assembly 27 is configured to negatively pressurize the plenum space 21 via the pressurizedconduit 19. This will draw air from around the patient's head back through thecover plate 35, minimizing the spread of airborne pathogens from the patient into the surrounding area. - As illustrated in
FIGS. 7 and 8 , the air handling assembly 27 further comprises a casing 28, anexternal port 29, animpeller 30, and afilter element 31. The casing 28 is mounted adjacent to therear end 12 of thechassis 10 with theimpeller 30 being positioned into the casing 28. Theexternal port 29 is externally mounted to the casing 28, ideally exposed to ambient air external to the casing 28. Thepressurized conduit 19 is connected to the casing 28, opposite theexternal port 29 across theimpeller 30. This positional arrangement ensures that any volume of air within the casing 28 is affected by theimpeller 30, either flowing towards thepressurized conduit 19 or towards theexternal port 29 depending on the mode of operation. Further, thefilter element 31 is mounted to the casing 28 between theimpeller 30 and thepressurized conduit 19. Theexternal port 29 is in fluid communication with thepressurized conduit 19 through thefilter element 31, ensuring that any volume of air traversing the casing 28 is filtered by thefilter element 31 regardless of flow direction. In a positive-pressure configuration, this ensures that the volume of air being forced into theexternal port 29 and ultimately onto the patient are appropriately free of contaminants. In a negative-pressure configuration, the volume of air drawn from around the patient is decontaminated prior to being exhausted into the ambient air from theexternal port 29. - As shown in
FIG. 2 , the present invention will functionally integrate any existing headboard as thechassis 10 by attaching the at least one mounting panel 37 thereto. Accordingly, the at least one mounting panel 37 further comprises an intermediate plate 38, a plurality offastener apertures 39, and aperimetric seal 40. The intermediate plate 38 constitutes a rigid structure spanning across the plenum space 21 to interconnect thesupply plenum 33 and thecover plate 35. The plurality offastener apertures 39 traverses the intermediate plate 38 between thefore end 11 and therear end 12 of thechassis 10, wherein the plurality offastener apertures 39 is distributed across the intermediate plate 38 corresponding to any existing mounting structures of any bed frame or headboard. As shown in the exemplary figures, the plurality offastener apertures 39 is arranged as a collection of multiple dissimilar mounting patterns, thereby enabling any single instance of the mounting panel 37 to attach to a variety of headboards, bedframes, or other furniture. Further, theperimetric seal 40 is perimetrically mounted to the intermediate plate 38 between the intermediate plate 38 and thesupply plenum 33 to ensure that the plenum space 21 is not compromised by any of the plurality offastener apertures 39. As shown inFIG. 4 , the plurality offastener apertures 39 is separated from the plenum space 21 by theperimetric seal 40 to prevent any pressure leakage from any unfilled instances defined within the plurality offastener apertures 39. - In another preferred embodiment, the present invention further comprises a deployable enclosure 42. The deployable enclosure 42 constitutes an air tent suitable for use in oxygen therapy treatments, or in cases where a highly infectious patient must be sequestered inside a room to prevent pathogenic spread. In reference to
FIGS. 5 and 6 , the deployable enclosure 42 further comprises at least onepivoting base 43, an overhead support 44, and acanopy 45. The at least onepivoting base 43 is mounted to thesupply plenum 33 to provide a stable, fixable base for the overhead support 44 to traverse between a stowed and a deployed position. Accordingly, the overhead support 44 is adjustably mounted to the at least onepivoting base 43 adjacent to therear end 12 of thechassis 10. In the deployed position the overhead support 44 is configured to extend from therear end 12 towards thefore end 11 of thechassis 10. Ideally, this positions the overhead support 44 above the head of a bed and over the upper body of a patient laying therein. Thecanopy 45 is mounted to the overhead support 44, wherein thecover plate 35 is substantially enclosed by thecanopy 45. This additionally encloses the patient within thecanopy 45, limiting airflow across thecanopy 45 and increasing the efficacy of the air handling assembly 27 in moderating the air surrounding the patient. - It is further considered that the geometry of the
supply plenum 33 and the at least one mounting panel 37 may not produce optimal airflow throughout the plenum space 21, resulting in uneven airflow through thecover plate 35. This uneven airflow may cause excess noise, lower recirculation rates, and otherwise prevent the patient from fully enjoying the benefits of the present invention. Accordingly, the plenum space 21 further comprises an internal cavity 22 and at least one diffuser element 23. In reference toFIGS. 2 and 5 , the at least one diffuser element 23 is mounted into the internal cavity 22 adjacent to the at least one mounting panel 37. At this intermediate position between thecover plate 35 and thesupply plenum 33, the at least one diffuser element 23 is configured to moderate airflow within the plenum space 21. The functionality of the at least one diffuser element 23 is proposed to function bimodally, i.e., the airflow across thecover plate 35 is ideally normalized regardless of the direction of airflow. - In another embodiment of the present invention, the at least one diffuser element 23 is a volume of diffusing material 24. The volume of diffusing material 24 ideally constitutes a collection of piled or shredded material placed within the internal cavity 22 in high-airflow regions within the internal cavity 22. Ideally, the overall air pressure within the internal cavity 22 is normalized by disrupting directional airflow across the internal cavity 22, thereby producing even air pressure through the
cover plate 35. - In yet another embodiment of the present invention, the at least one diffuser element 23 is a plurality of baffle inserts 25 as shown in
FIGS. 2 and 3 . The plurality of baffle inserts 25 defines rigid aerodynamic surfaces configured to redirect high-speed airflow across the internal cavity 22. The configuration of the plurality of baffles is generally contemplated to equally distribute a stream of air across thecover plate 35, but this configuration may be supplanted with a configuration targeting specific areas without departing from the original spirit and scope of the present invention. - In an instance wherein the
chassis 10 supplants a standard headboard, as shown inFIGS. 6 and 7 , it is proposed that thechassis 10 will enable some vertical adjustability of the bed frame. In at least one embodiment thechassis 10 further comprises a structural panel 13, a plurality oflift actuators 14, and a plurality ofbase plates 15. The structural panel 13 broadly refers to the substructure of a conventional headboard, wherein the headboard is adapted for use with the other functional components of the present invention as outlined above. The plurality oflift actuators 14 defines any user-adjustable, extensible members suitable for supporting the weight of the present invention, a supported bed frame, and a patient. In one instance, the plurality oflift actuators 14 are manually adjustable posts threaded into the structural panel 13. In another instance, the plurality oflift actuators 14 defines a series of electrically operated linear actuators receiving operating power from thepower supply 17. In yet another instance, the plurality oflift actuators 14 is a series of pressurized cylinders, wherein the cylinders are extensible by pumping increased pressure thereto. Each of the plurality ofbase plates 15 are mounted to each of the plurality oflift actuators 14, opposite the structural panel 13. The plurality oflift actuators 14 is configured to moderate an offset between the structural panel 13 and the plurality ofbase plates 15, wherein the offset defines the elevation of the structural panel 13 above the plurality ofbase plates 15. This elevation translates to an inclination or declination of the patient, thereby enabling a patient to find a comfortable resting position. - As outlined previously, the present invention aims to filter any volume of air traversing through the air handling unit to reduce the prevalence and spread of airborne contaminants. While the above-described instances of the present invention broadly encompass various forms of passive filtration, it is further suggested that the present invention may utilize active sterilization measures to eliminate biological hazards. More specifically, the present invention further comprises a plurality of
emitters 47 configured to emit ultraviolet radiation in at least one embodiment. In reference toFIG. 3 the plurality ofemitters 47 is internally mounted to thesupply plenum 33 and electrically connected to thepower supply 17. The plurality ofemitters 47 is configured to produce ultraviolet radiation to sterilize the plenum space 21, wherein the plurality ofemitters 47 exposes any volume of air within the plenum space 21 to prolonged fractions of ultraviolet radiation of approximately 260nm wavelength. - Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
