Description

Background

[0001] The present application relates to a helmet, and more particularly to a helmet which maintains ventilation around the head of the wearer and facilitates access to wounds such as for the application of medicament or dressings.

[0002] Helmets are well known. Helmets are also used to protect existing injuries during periods of activity and periods of rest. Other helmets with additional, modular, functionalities such as for monitoring sleep, providing communications devices, or providing an apparatus for increased hair growth are also known.

[0003] US9232827B1 discloses a cranial protective helmet having a pair of components made of an exterior hard plastic shell with sufficient flexibility to accommodate the patient with interior cushioning liners conforming to a side of the patient's skull. Each component of the helmet can conform to a side of the patient's head and accommodate an insertion of the patient's head by relative movement with one or more fastener units securing the helmet components to the patient. Openings can be provided to accommodate monitoring instrumentation after a craniectomy operation. The components can be separate or minimally connected to enable a rotational opening. Fastener units can provide a secure connection of the components and an elastic attachment about the patient's head. The apparatus disclosed does not comprise easily attachable and detachable modular panels for facilitating access to different regions of the wearer's head. The cushioning liners also contact the user's head.

[0004] US2012059440 discloses an apparatus for providing increased hair growth and healthier scalp. The apparatus comprises of a swappable-zoned flexible helmet. The flexible helmet device consists of a laser or LED array (from 25 to 300 tiny lasers or 25-300 LEDs) directed at the scalp. The disclosed treatment is subjecting the affected scalp to flexible helmet equipped with the laser or LED array, 3 times a week for a minimum of 20 minutes per session to enable the absorption of laser or light from LED. The apparatus disclosed in this application is not designed for comfort while the user is lying down, for example, with their head on a pillow, and would not facilitate easy access to wounds on the scalp.

[0005] US2011197327A1 discloses a helmet system that enables a user of the helmet system to customize the helmet system according to personal taste, a task at hand, responsibilities within a tactical group (e.g., communications, command, etc.), and / or according to other parameters. The customization of the helmet system may include a customization of electronics modules carried on the helmet system that optionally provide communications, environment detection, health or biometrics monitoring, power, information transmission / reception, information processing, and / or other functionalities. The customization of the helmet system may include a customization of structural components that enable the user to balance the structural protection provided to the user against other considerations. The other considerations may include, for example, weight, form factor, comfort, and / or other considerations. The apparatus of this disclosure is in direct contact with the head of the wearer and therefore may aggravate head wounds.

[0006] Patients of hair transplant procedures may have large areas of their head which need protecting after the procedure. A further challenge is that multiple regions may need protecting, corresponding to donor and treatment regions on different parts of the head. It is important to both protect these regions while also avoiding the helmet itself disturbing them.

[0007] There is therefore a need for a helmet which is readily adaptable to different wound locations and is comfortable for the user during periods of rest.Summary

[0008] A helmet is provided, comprising a shell for protecting a wearer's scalp; and a support structure extending between a first ear connector and a second ear connector configured to engage a wearer's ears in use to wear the helmet, the support structure configured to support the shell in use away from the wearer's scalp when worn. In other words, the shell is spaced from the wearer's scalp. That is, the shell does not contact or touch the wearer's scalp. Such a helmet is useful for protecting the head and / or scalp of the wearer, particularly when the scalp is sore due to injury or recent surgical treatment. The helmet can also protect the hair and / or makeup of the wearer.

[0009] The ear connectors may be biased by the support structure to provide a retaining force on the wearer's head when worn. This helps to retain the helmet on the head without contacting the scalp. Particularly, the ear connectors may be biased towards one another.

[0010] This may be such that the first ear connector and second ear connector are connected to one-another by a horseshoe- or U- shaped piece of material, wherein the spacing between the first and second ear connectors when the helmet is not being worn is less than the spacing between the ears of the wearer. The spacing between the first and second ear connectors may be 0% - 5%, 5% - 10%, or 10% - 25% less than the spacing between the head of the wearer depending on the material from which the horseshoe- or U- shaped piece of material is made. Alternatively, the support structure may define a different shape over the head of the wearer, such that when the helmet is not being worn the spacing between the first and second ear connectors is less than the spacing between the ears of the wearer. The spacing between the first and second ear connectors may be 0% - 5%, 5% - 10%, or 10% - 25% less than the spacing between the head of the wearer.

[0011] The support structure may comprise a grid of struts extending between the first ear connector and the second ear connector. The struts may be made of a rigid plastic, aluminium, stainless steel, other lightweight metal, or carbon fibre. The grid may serve to reduce the weight of the helmet compared to having a solid structure. The grid may further facilitate the use of modular panels, which can be attachable to and detachable from the support structure.

[0012] The shell may comprise modular panels attachable to and detachable from the support structure. These modular panels may be positioned so as to form a near complete covering of the head of the user, or be positioned only to cover specific regions, as dictated by a clinical need. The panels may be detachable to facilitate the easy, localised application of medicament and / or dressings to wounds. Further, the helmet may become more comfortable by removing panels which are not needed, such as, for example, by becoming lighter, and / or by becoming more flexible.

[0013] The modular panels may be constructed from carbon fibre or stainless steel. This could be entirely or at least predominantly (i.e. at least 50%). These are strong materials which will result in the helmet shell having sufficient rigidity, without too much weight.

[0014] The modular panels may be attachable to or positioned between the struts of the support structure. The attachment of the modular panels to the struts may provide an easy attachment mechanism for patients and / or clinicians. In particular, specific panels may connect between specific struts; i.e. panels shaped to cover the side of the head may only fit between struts in this location on the support structure, for example. The panels may further be colour-coded or otherwise identifiable as being positionable between particular struts. The struts may also be colour-coded or otherwise identifiable, such as with numbers. For example, red panels may be attachable between struts which are half red, blue panels attachable between struts which are half blue, and so on, with each strut having at least one colour, number, or other marking, corresponding to the panel attachable on either side of the strut where appropriate.

[0015] The helmet may further comprise connector elements comprising at least one first fixing (which may be a hole) for securing struts to form the grid. The connector elements may allow for easy distribution of the helmet in disassembled form, and easy assembly through insertion of the struts into the connector elements.

[0016] The connector elements may further comprise at least one second fixing for removably attaching modular panels. The connector elements may allow for easy distribution of the helmet in disassembled form, and easy assembly through attachment of the modular panels to the connector elements.

[0017] The modular panels may be attachable to the support structure with captive screws. In other words, the modular panel may retain one or more captive screws for attaching the modular panel to the support structure; the captive screws do not disconnect from the panel in the same manner as the captive screws connect to or disconnect from the support structure. This has the advantage that the screws remain attached to the panel when the panel is removed, and so cannot fall into the wound, or otherwise inside the helmet.

[0018] The shell may extend to the occipital protuberance and at least partially cover the occipital and / or frontal and / or temporal bones. This has the advantage of covering areas which may be used as donor or recipient regions in hair transplant procedures; these areas would therefore benefit from protection from such a helmet as that provided in the present disclosure.

[0019] The shell may extend to the 1 st< cervical vertebrae. This has the advantage of covering areas which may be used as donor or recipient regions in hair transplant procedures; these areas would therefore benefit from protection from such a helmet as that provided in the present disclosure.

[0020] The shell may at least partially cover the parietal bone. This has the advantage of covering areas which may be used as donor or recipient regions in hair transplant procedures; these areas would therefore benefit from protection from such a helmet as that provided in the present disclosure.

[0021] The shell may extend to within 2 cm of the glabella. This has the advantage of covering areas which may be used as donor or recipient regions in hair transplant procedures; these areas would therefore benefit from protection from such a helmet as that provided in the present disclosure.

[0022] The shell may be air permeable. The shell may be formed of a mesh. The mesh structure may comprise a rigid material such as plastic or metal, or a composite material, such as stainless steel, aluminium, or carbon fibre. The mesh structure may be any known form of mesh structure, such as a lock crimp, inter-crimp, stranded, or woven mesh. Alternatively or additionally, the shell may be air permeable through comprising a breathable fabric. Each individual modular panel (or at least some of the modular panels) may be formed of a mesh.

[0023] Breathability may alternatively be achieved by spacing between modular panels. This may be achieved through shaping the panels such that their edges are not contiguous with the support structure and / or the neighbouring modular panel; for example, the modular panel may comprise a concave section between attachment points. Alternatively or additionally, there may be spaces between struts to which no panel is fitted. Alternatively or additionally, the struts of the support structure may have gaps in the middle; with attachment points for neighbouring modular panels either side of the gaps.

[0024] The helmet may further comprise a chin strap. The chin strap may be attached to the first ear connector and the second ear connector for engaging a user's chin in use. The chin strap may further comprise a chin rest. These features may improve the fit of the helmet. The chin strap may be attached to the support structure and / or a modular panel.

[0025] The ear connectors may comprise sub-cups, which are connectable to one another. The sub-cups allow for the helmet to be worn by wearers with different head shapes, as connection of additional sub cups serves to reduce the spacing between the point of the ear cups which engage the wearer's ears (thereby fitting wearers with smaller heads).

[0026] The sub-cups may be connectable through a screw connection. Alternatively or additionally, the sub-cups may be magnetically attachable. The sub-cups may comprise complementary convex and concave surfaces. This may facilitate a quick addition or removal of additional sub-cups, while providing strong attachment between adjacent sub-cups.

[0027] The ear connector may comprise a cushioning element for the comfort of the user, for engaging the wearer's head in use. The cushioning element can help to make the helmet more comfortable and a better fit. The cushioning element may be connected to a sub-cup, or any other part of the ear connector.

[0028] The helmet may further comprise a speaker. The speaker may be removably attached to the ear connector. Each ear connector may comprise a speaker. The speaker may be removably attached to a sub-cup. The speaker may be attached to the ear connector or sub-cup through a screw fit.

[0029] Each ear connector may comprise at least one attachment point for attaching a strap to. The at least one attachment point may be a loop and / or may be spaced around the circumference of the ear connector. The at least one attachment point may be positioned in use between the support structure and the head of the wearer. The at least one attachment point may also be a buckle, adjustor strap, or other such feature as are known in the art. This has the advantage that straps can be run around the head from different attachment points to secure the helmet, thereby allowing the helmet to be secured without a strap contacting a wound.

[0030] The helmet may further comprise at least one strap connectable to the attachment points on the first and second ear connectors. This may provide easy adjustment of the helmet.

[0031] The straps may be made of an elastic material. This may provide a retaining force when stretched over the wearer's head.

[0032] The helmet may further comprise a face shield for protecting at least part of the cheeks and / or nose and / or eyes, and / or forehead, spaced in use from the face of the user when worn.

[0033] The face shield may itself comprise a forehead panel for covering the forehead of the user. The forehead panel may at least partially define an eye opening. The eye opening may be aligned with the wearer's eyes in use.

[0034] The face shield may comprise a nose panel, for covering the nose of the user. The nose panel may at least partially define an eye opening. The eye opening may be aligned with the wearer's eyes in use. The nose panel may be shaped so as to have a central raised portion to maintain spacing between the nose panel and the wearer's nose in use.

[0035] The nose panel and forehead panel may themselves comprise the features of modular panels described herein.

[0036] The forehead panel and nose panel may come pre-formed as a single piece, or may be modular pieces which are individually connectable to the helmet. The use of fewer modular panels where possible may reduce device sterilisation costs / time.

[0037] The forehead panel and nose panel may have overlapping screw holes for attaching to the helmet with the same screw in use. The forehead panel and / or nose panel may be attachable to the helmet through either the ear connectors or the support structure. The face shield may be attachable to the helmet through either the ear connectors or the support structure.

[0038] The face shield may comprise at least one eye opening, aligned with the wearer's eyes in use. As noted above, this can be defined by a combination of the forehead panel and nose panel. Alternatively, the eye opening can be defined on any suitable part of the face shield.

[0039] The helmet may further comprise at least one eye module for covering the at least one eye opening. The eye module may be transparent or translucent for seeing through, or may be opaque.

[0040] The face shield may comprise a mouth panel configured to overlie the user's mouth when worn. Such a mouth panel is useful for protecting the mouth, jaw, and / or lips of the wearer, particularly following an injury or cosmetic intervention, such as lip filler treatment.

[0041] Any of the features described above may be combined with any combination of other features described above.

[0042] Also provided is a method of protecting a user's head comprising: providing the helmet of the present disclosure; and putting the helmet on the user.Brief Description of the Drawings

[0043] The present specification makes reference, by way of example only, to the accompanying drawings in which: Figure 1 shows a side view of a helmet being worn in use by a wearer according to an embodiment; Figure 2 shows a side view of a helmet being worn in use by a wearer according to an embodiment; Figure 3 shows a rear view of a helmet being worn in use by a wearer according to an embodiment; Figure 4 shows a frontal plane cross-section of a helmet being worn in use by a wearer according to an embodiment; Figure 5 shows an ear connector of a helmet; Figure 6a shows the connector elements in the support structure; Figure 6b shows a side-view of a connector element; Figure 7a shows a view of an ear connector as would be seen looking at the transverse plane in use; Figure 7b shows a view of the ear connector orthogonal to that of 7a; Figure 7c shows a sub-cup; Figure 8a shows a forehead panel of a helmet; Figure 8b shows a nose panel of a helmet; Figure 8c shows the forehead panel of Figure 8a and the nose panel of 8b attached to a helmet Figure 9a shows a mouth module of a helmet; and Figure 9b shows the mouth module of Figure 9a attached to a helmet. Detailed Description of the Drawings

[0044] Figures 1 to 4 show various embodiments of a helmet 2 in various orientations. The helmet 2 is shown on the head 4 of a wearer or user. The wearer or user may be an adult or a child, and may be male or female. The helmet 2 may be sized and shaped accordingly, for example based on average dimensions of a head 4. These average dimensions may be selected based on certain characteristics such as sex, age, etc. The wearer's head 4 has a scalp which represents the region of the head 4 where hair typically grows - such as a portion of the head 4 corresponding to the user's cranium. the wearer may have a head wound 6, which requires protection. This head wound 6 could be any type of wound. For example, appearing anywhere on the head, such as the scalp, back of the head, around the eyes, nose, forehead, or mouth. In specific examples, this could be a wound 6 which has resulted from a surgery such as a hair transplant. Of course, the wearer may not have any head wound 6 and may be wearing the helmet 2 for other purposes.

[0045] The helmet 2 comprises a shell 26 for protecting the wearer's scalp. That is, the shell 26 prevents damage to the wearer's scalp. This could be, for example, by acting as a physical barrier blocking or covering at least a portion of the wearer's head.

[0046] The helmet further comprises a support structure 10 extending between a first ear connector 8 and a second ear connector 8. Figures 1 and 2 are side views and so each show one of the ear connectors 8 (specifically the right ear connector from the wearer's perspective). The ear connectors 8 are configured to engage a wearer's ears in use to wear the helmet 2. For example, the first ear connector 8 may contact the wearer's right ear and the second ear connector 8 may contact the user's left ear (or vice-versa). In specific examples, each ear connector 8 may receive the user's respective ear within the ear connector 8. That is, they may be over-ear ear connectors 8. To achieve this, each ear connector 8 may have a cavity or recess which receives the respective ear.

[0047] The support structure 10 is configured to support the shell 26 in use away from the wearer's scalp. That is, when the helmet 2 is worn, with each ear connector 8 engaging with the respective ear, the shell 26 is spaced from the wearer's scalp. In other words, the shell 26 is not contacting the wearer's scalp. It may also be the case that the support structure 10 itself is not contacting the wearer's scalp. That is, it may be only the ear connectors 8 which contact the user's head 4. This allows the shell 26 to protect the wearer's head (specifically for example the scalp) without being in direct contact therewith.

[0048] For example, the support structure 10 may be arranged such that the shell 26 is always at least 0.5 centimetres from the wearer's scalp, preferably at least 1 centimetre or 2 centimetres from the wearer's scalp.

[0049] In supporting the shell 26 in use away from the wearer's scalp, the helmet 2 does not apply any pressure onto the scalp. Particularly, when the wearer is laying down or otherwise resting the head 4 on a surface. This can help prevent the head wound 6 from being aggravated. Likewise, this could protect any hair styles or make-up which had been applied to the user from damage.

[0050] The shell 26 may be air permeable, such as through comprising air permeable material and / or a mesh structure. The mesh structure may comprise a rigid material such as plastic or metal, or a composite material, such as stainless steel, aluminium, or carbon fibre. The mesh structure may be any known form of mesh structure, such as a lock crimp, inter-crimp, stranded, or woven mesh. Alternatively or additionally, the shell may be air permeable through comprising a breathable fabric material. Breathability may additionally or alternatively be achieved through shaping the modular panels 27 such that their edges are not contiguous with the support structure 10 and / or the neighbouring modular panel 27; for example, the modular panel 27 may comprise a concave section between connector elements 24, wherein the edges of the modular panel 27 are curved away from the neighbouring strut 11. Alternatively or additionally, there may be spaces between struts 11 to which no modular panel 27 is fitted. Alternatively or additionally, the struts 11 of the support structure 10 may have gaps in the middle; with attachment points for neighbouring modular panels 27 either side of the gaps.

[0051] Figure 1 further shows how the ear connectors 8 may each comprise one or more strap fixings 16 (such as a loop, or other attachment point). These strap fixings 16 may specifically be provided on an ear cup of the ear connector 8. A strap 12 may be attached to these strap fixings 16, such that the strap 12 extends between the first ear connector 8 and the second ear connector 8. The strap 12 being for at least partially (further) securing the helmet 2 on the head 4 of the wearer. This strap 12 can be designated as a head strap 12 if required to differentiate it from other straps of the helmet 2. In certain cases, there may be multiple straps 12 extending between strap fixings 16. The head strap 12 may be made from an elastic material. In certain cases, the length of the head strap 12 may be adjustable.

[0052] The helmet 2, may comprise a chin strap 14 for engaging the user's chin in use. The chin strap 14 may be in addition to, or an alternative to, the head strap 12 The chin strap 14 may at least partially (further) secure the helmet 2 on the head 4 of the wearer. The chin strap 14 may be secured to a loop, attachment point or chin strap fixing 18 on the ear connectors 8. This chin strap fixing 18 may be the same as the strap fixings 16 for the head straps 12. The chin strap 14 may be made from an elastic material. The chin strap 14 may be the same as the head strap 12 - possibly with a different length. The length of the chin strap 14 may be adjustable. The chin strap 14 may further comprise a chin rest element 66 (such as shown in the helmet 2 of Figure 8c).

[0053] The helmet 2, may comprise a face shield 20. That is, a part of the helmet 2 which covers the wearer's face. An example of such a helmet 2 is shown in the embodiment of Figure 2. Unless otherwise expressly stated to the contrary, the embodiment of Figure 2 is the same as that of Figure 1. Any features discussed in relation to the embodiment of Figure 1 are equally applicable to the embodiment of Figure 2, and vice-versa.

[0054] The face shield 20 may cover all or part of the cheeks and / or eyes and / or nose, and / or forehead of the wearer. Again, in use the face shield 20 may be spaced from these parts of the wearer's face. The face shield 20 may be supported by the support structure 10 of the helmet 2.

[0055] An example face shield 20 is shown in Figures 8a to 8c and will be discussed in more detail below. In brief, the face shield 20 may comprise a forehead panel 49 or module. This forehead panel 49 is configured to overlie a user's forehead in use.

[0056] The face shield 20 may additionally or alternatively comprise a nose panel 64 or panel. The nose panel 64 is configured to overlie a user's nose in use and protect the nose. The nose panel 64 may contact the user's nose when the helmet 2 is worn. Alternatively, the nose panel 64 may be spaced from the user's nose. The nose panel 64 may be shaped so as to have a central raised portion to maintain spacing between the nose panel 64 and the wearer's nose in use.

[0057] The shell 26 may extend to the user's occipital protuberance. That is, the shell 26 may be configured to overlie the occipital protuberance in use when worn.

[0058] The shell 26 may at least partially (or entirely) cover one or more of the occipital, and / or frontal, and / or temporal bones. In certain cases the shell 26 may extend to the 1 st< cervical vertebrae (such that in use the helmet 2 overlies the 1 st< cervical vertebrae). The shell 26 may at least partially (or entirely) cover the parietal bone.

[0059] In certain examples the shell 26 may extend to within 2 cm of the glabella. The addition of the face shield 20 can then extend beyond the glabella.

[0060] Any of these extents of the shell 26, and bones overlayed in use, may be individually incorporated as appropriate for a particular helmet 2.

[0061] In certain cases, the shell 26 may be formed of a plurality of modular panels 27. Figure 3 shows a rear view of a helmet 2 in accordance with such an embodiment. Unless otherwise expressly stated to the contrary, the embodiment of Figure 3 is the same as that of Figures 1 and / or 2. Any features discussed in relation to the embodiments of Figure 1 and / or 2 are equally applicable to the embodiment of Figure 3, and vice-versa.

[0062] The helmet 2 comprises a shell 26. The shell 26 may comprise modular panels 27. The modular panels 27 may be removably attachable and detachable from the support structure 10. That is, without damaging the shell 26. Particularly this is to the support structure 10. The modular panels 27 can be selectively attached and detached from the support structure 10 to customise the helmet 2. For example, there may be one or more different types of modular panels 27 which can be attached to the helmet 2 so as to overlie different parts of the wearer's head. The modular panels 27 (or at least some of the modular panels 27) may be air permeable, such as comprising a mesh. Figure 3 shows how the modular panels 27 may be arranged in an array about the shell 26. In certain cases, the user may choose to selectively leave areas on the shell without any modular panel(s) 27.

[0063] The modular panels 27 may connect between specific struts 11; i.e. modular panels 27 shaped to cover the side of the head may only fit between struts 11 in this location on the support structure 10, for example. The modular panels 27 may further be colour-coded or otherwise identifiable as being positionable between particular struts 11. The struts 11 may also be colour-coded or otherwise identifiable, such as with numbers. For example, red modular panels 27 may be attachable between struts 11 which are half red, blue modular panels 27 attachable between struts 11 which are half blue, and so on, with each strut 11 having at least one colour, number, or other marking, corresponding to the modular panel 27 attachable on either side of the strut 11 where appropriate. Alternatively, only the screw holes on each panel and strut may be colour-coded, or otherwise identifiable, such as with numbers. Alternatively or additionally, screw holes on the connector elements 24 may be colour-coded, or otherwise identifiable, such as with numbers.

[0064] The struts 11 may be connected to one another by connector elements 24. Connecting the struts 11 in this manner can form the support structure 10. For example, the connector elements 24 may comprise at least one first fixing 32 such as recesses or holes for receiving adjacent and / or intersecting struts 11.

[0065] The support structure 10 may comprise a grid of struts 11 extending between the first ear connector 8 and the second ear connector 8. An example of such a grid of struts 11 is shown in Figures 6a and 6b. The struts 11 may be elongate bars or plates, with gaps in between. The modular panels 27 can then be attached to the struts 11 to span these gaps. In other words the modular panels 27 may be positioned between the struts 11.

[0066] The modular panels 27 may be attachable to the support structure 10 in any suitable manner. This could include an interference or snap fit. However, in some cases a fastener may be used to attach the modular panels 27 to the support structure 10. In a particular example, the modular panels 27 are attachable to the support structure 10 with captive screws. The screws are captive in that they are retained by a component of the helmet 2 and cannot readily be removed from that component. The captive screws may not disconnect from the modular panel 27 in the same manner as the captive screws connect to or disconnect from the support structure 10. For example, each modular panel 27 may retain one or more captive screws. The support structure 10 (such as the connector elements 24) may then comprise corresponding threaded holes. Of course, the alternative is also possible with the support structure 10 (such as the connector elements 24) retaining the captive screws and the threaded holes being in the modular panels. To attach the modular panel 27 to the support structure 10 the captive screw is received in the threaded hole and turned to engage the captive screw with the threaded hole.

[0067] The shell 26 may comprise flat and / or curved modular panels 27. In certain cases, there may be a mixture of flat modular panels 27 and curved modular panels 27, used at different parts of the helmet 2. In general, the shell 26 needs to conform to the user's head and the modular panels 27 can be selected accordingly.

[0068] The shell 26 may be predominantly (or entirely) constructed from carbon fibre or stainless steel. In other words, the shell 26 may consist essentially of (or indeed consist of) carbon fibre or stainless steel. Specifically, the modular panels 27 may be constructed from (consisting essentially of or consisting of) carbon fibre or stainless steel. In certain cases, the struts 11 may themselves be constructed from (consisting essentially of or consisting of) carbon fibre or stainless steel. The struts and / or modular panels may alternatively be constructed from (consisting essentially of, or indeed consisting of) plastic or metal, such as aluminium.

[0069] Figure 4 shows a frontal plane cross-section of a helmet 2 being worn in use by a wearer. This may be the helmet 2 of any of the embodiments discussed herein. Again, any features discussed in relation to Figure 4 are equally applicable to any of the embodiments. The cross-section is applied to the helmet 2 and not to the user's head which is shown in a schematic front view.

[0070] The ear connectors 8 shown in Figure 4 are over-ear ear connectors 8. That is, the user's ears are received in the ear connectors 8, such as in a cavity or recess thereof. The ear connectors 8 may be biased to provide a retaining force on the wearer's head 4 when worn. Specifically, this could be by being biased towards one another when worn. This biasing can be provided by the support structure 10.

[0071] The ear connectors 8 may provide said retaining force through being connected to one-another by an approximately horseshoe- or U-shaped piece of material 100, forming part of the support structure 10. For example, the spacing between the first and second ear connectors 8 when the helmet 2 is not being worn (also called "at rest") is less than the spacing between the ears of the wearer. The spacing between the first and second ear connectors 8 when the helmet is not being worn may be 0% to 5%, 5% to 10%, or 10% to 25% less than the spacing between the ear connectors when the helmet is worn on head of the wearer depending on the material from which the horseshoe- or U- shaped piece of material 100 is made. This could be determined based on standard head sizes. In certain cases, there may be different helmets selectable by size and / or characteristics (sex, age, etc.) of the wearer. The spacing between the ear connectors 8 may be adjustable. For example, by having each ear connector 8 on an extendable section extending from the horseshoe- or U- shaped piece of material 100.

[0072] Alternatively, the support structure 10 may define a different, but functionally equivalent shape over the head 4 of the wearer, such that when the helmet 2 is not being worn, the spacing between the ear connectors is less than the spacing between the ears of the wearer. The spacing between the first and second ear connectors when the helmet is not being worn may be 0% to 5%, 5% to 10%, or 10% to 25% less than the spacing between the ear connectors when the helmet is worn on the head 4 of the wearer.

[0073] When worn on the user's head, the ear connectors 8 are biased towards one another - effectively gripping onto the user's head 4. This can then help to retain the helmet 2 on the user's head. This engagement can help to space the shell 26 from the user's scalp since contact with the scalp may not be necessary to locate the helmet 2.

[0074] Figure 5 shows an example of an ear connector 8 on the head 4 of a wearer, engaging the ears of the wearer. This ear connector 8 can be used with any of the embodiments discussed herein. The ear connector may comprise multiple fixings, 16, 18, 28, between the support structure 10 and the head 4 of the wearer (i.e. the medial or inner side of the support structure), such as strap fixings 16, chin strap fixings 18, or other medial fixings 28. That is, the support structure 10 is outward (with respect to the centre of the helmet 2, or the user's head) of the fixings 16, 18, 28. The fixings 16, 18, 28 are suitable for connecting straps 12, 14 for (further) securing the helmet 2 on the head 4 of the wearer in use. This can include, for example, the head strap 12 and / or chin strap 14 discussed above. The straps 12, 14 are selectively attachable to the fixings 16, 18, 28.

[0075] Multiple fixings 16, 18, 28 may facilitate the helmet 2 being secured with straps in a way that does not interfere with or contact the wound 6, for a variety of wound positions. That is, an appropriate combination of fixings 16, 18, 28 can be selected based on the location of the head wound 6. For example, this may be so that the head strap 12 does not overlie any head wound 6 in use when the helmet 2 is worn. Lateral fixings 30 may be positioned on the lateral (i.e. outer) side of the support structure 10, for further straps 12, 14 and / or securing additional devices to the helmet 2.

[0076] As noted above, Figure 6a shows an example of a grid of struts 11 forming part of the support structure 10. The struts 11 may be connected by connector elements 24. The connector elements 24 may comprise at least one first fixing 32, such as a hole for securing the struts 11 in the support structure 10. The connector elements 24 may further comprise at least one second fixing 33, for removably attaching modular panels 27. The at least one second fixing 33 may be a threaded hole. Additionally or alternatively, the at least one second fixing 33 may be a press stud. The at least one second fixing 33 may be transverse, such as substantially perpendicular or perpendicular, to the hole 32.

[0077] The connector element 24 may comprise an inner element and an outer element, wherein the inner element in use is closer to the wearer's skull when worn, and the outer element is further from the wearer's skull when worn than the inner element. The inner element and outer element may separately or collectively define one of more holes 32 configured to fit a strut 11. The inner element and outer element may be connected by a tightening mechanism, configured to lock the strut 11 in place. The tightening mechanism may be screws through both the inner and outer elements. The connector element 24 may comprise a first set of screw holes configured to tighten together the inner element and outer element together, thereby locking a strut 11 into the element. The first set of screw holes could additionally function as the at least one second fixing 33 for removably attaching modular panels 27. The set of screw holes may be on the outer element.

[0078] Of course, alternative connector elements 24 are possible, such as those where the strut 11 is received in a bore and held in place via an interference fit. This may or may not have the inner and outer element discussed above.

[0079] Figures 7a to 7c shows an example of an ear connector 8. This ear connector 8 can be used with any of the embodiments discussed herein. The ear connector 8 of Figure 7 comprises one or more sub-cups 38. This sub-cup 38 may connect to the support structure 10 such as through a sub-cup fixing 34. For example, this may be with the horseshoe- or U- shaped piece of material 100. Figure 7a shows an example with two sub-cups 38. However there may be more or fewer sub-cups 38.

[0080] A cushioning element 36 is attached to the innermost sub-cup 38, for contacting and / or receiving the user's ear in use. The cushioning element 36 can provide a comfortable fit around the ears of the user.

[0081] In certain examples, the cushioning element may comprise a foam - particularly a solid foam.

[0082] Each sub-cup 38 may be coupleable to additional sub-cups 38 - such as the two sub-cups 38 shown in Figure 7a. The connection between sub-cups 38 may be through a screw or pin connection 40, an interference fit, a snap fit, or any other type of connection. The sub-cup 38 (particularly the outermost sub-cup 38) may comprise a fixing 34 for the support structure 10 and / or horseshoe- or U- shaped piece of material 100. Each sub-cup 38 may be identical. However, in certain cases there may be an outermost sub-cup 38 which is fixed to the support structure 10. Additional sub-cups 38 which are different to the outermost sub-cups 38 can then be attached to the outermost sub-cups 38. This can reduce the spacing between the ear connectors 8, for example to provide the biasing force discussed above.

[0083] The ear connector 8 may comprise a recess, cavity or void 44, 48 for receiving the ears of the wearer. In use, the recess or cavity 44, 48 can receive the ear such that the ear connector 8 substantially (or entirely) surrounds the ear of the user. The recess or cavity 44, 48 which may be a through-hole 44, or a closed cavity 48. In certain cases, the recess or cavity 44, 48 may be designed to receive a complementary extrusion 46 on a further sub-cup 38. The sub-cups 38 may comprise complementary convex and concave surfaces. This can then lead to an interference fit between the sub-cups 38 to attach the sub-cups 38 to one another. Alternatively or additionally, the sub-cups 38 may be magnetically attachable to one another. This could include, for example, one or more magnets and / or magnetic regions on each sub-cup 38.

[0084] The helmet 2 may further comprise one or more speakers. Specifically there may be two speakers - one for each ear connector 8. These speakers can be permanently attached to the respective ear connector 8. However, in particular examples the speakers can be removably attachable and detachable to the ear connectors 8. For example, the ear connectors 8 (such as the sub-cups 38) may comprise one or more speaker fixings 42 which the speaker attaches to. This could be a threaded hole, or could be an interference fit or snap fit. The speakers can play sound in the ear connectors 8. The or each speaker may comprise a suitable audio driver, or have one connected thereto. These speakers can be incorporated into any of the embodiments discussed herein.

[0085] As noted above, Figures 8a to 8c show a possible configuration of a face shield 20 which can be used with any of the embodiments discussed herein. Figure 8a shows a forehead panel 49 for covering at least part of the glabella of the wearer. The forehead panel 49 may cover the entirety of the glabella of the wearer. The forehead panel 49 may be attached to the helmet 2, for example to the support structure 10.

[0086] The forehead panel 49 may at least partially define an edge of an opening 52. In use this edge 52 can be aligned with the wearer's eyes. This opening can be for allowing the wearer to see when wearing the helmet 2. The forehead panel 49 may be removably attachable and detachable to the rest of the helmet 2 in any of the ways discussed above in relation to the modular panels 27. In certain examples, the forehead panel 49 may comprise one or more fastener holes 54, 56 for receiving a fastener, such as a screw. There may be one or more captive screws retained by the forehead panel 49 for engaging threaded holes of the support structure 10 (or vice-versa). Of course other attachment methods such as interference fits or snap fits could be used.

[0087] Figure 8b shows a nose panel or panel 64, for covering at least part of the nose of the wearer. Collectively the forehead panel 49 and nose panel 64 may form the face shield 20. The nose panel 64 may be attachable and detachable to the helmet 2. This could be to the support structure 10, either directly or indirectly. For example, the nose panel 64 could connect to the forehead panel 49, and the forehead panel 49 then connects to the support structure 10 (or vice-versa). The nose panel 64 may at least partially define an edge of an opening 62. In use, this edge 62 can be aligned with a wearer's eyes. This opening can be for allowing the wearer to see when wearing the helmet. The nose panel 64 may comprise a raised portion 65 for maintaining a gap between the nose panel 64 and the nose of the wearer in use.

[0088] Collectively the edge 52 of the forehead panel 49 and the edge 62 of the nose panel 64 can define an eye opening 68 (or at least part of an eye opening 68). This eye opening 52 aligned with the user's eyes to allow the user to see out when wearing the helmet 2. The helmet 2 may further comprise an eye module connectable to and suitable for covering the eye opening 68. This eye module can be formed of a transparent or translucent material to allow the user to see through the eye opening 68. Alternatively, an opaque eye module may be provided. For example, the user could select an opaque eye module to sleep wearing the helmet 2. The eye module may be selectively attachable so that a transparent / translucent eye module is used when the user is wearing the helmet 2 when not sleeping, and an opaque eye module is used when the user is sleeping wearing the helmet 2.

[0089] The nose panel 64 may be removably attachable and detachable to the rest of the helmet 2 in any of the ways discussed above in relation to the modular panels 27, and / or the forehead panel 49. In certain examples, the forehead panel 49 may comprise one or more fastener holes 58, 60 for receiving a fastener, such as a screw. There may be one or more captive screws retained by the nose panel 64 for engaging threaded holes of the support structure 10 or the forehead panel 49 (or vice-versa). Of course other attachment methods such as interference fits or snap fits could be used.

[0090] The forehead panel 49 and nose panel 64 may be attachable to one another through fastener holes 54, 56, 58, 60 (such as screw holes). The forehead panel 49 and nose panel 64 may be pre-formed together as a single piece face shield 20.

[0091] In certain cases, the forehead panel and / or nose panel may be connectable to the ear connectors 8, as shown in Figure 8c. This could be a direct connection, such as via one or more fasteners, an interference fit and / or a snap fit.

[0092] The helmet 2 may further comprise a mouth panel 70 (or mouth shield), shown in Figures 9a and 9b. The mouth panel 70 being arranged to overlie, in use, the user's mouth. The mouth panel 70 is suitable for protecting the user's mouth.

[0093] While these Figures show the mouth panel 70 in an example with the forehead panel 49 and nose panel 64, it is appreciated that this is not necessarily the case and each can be provided independently. The mouth panel 70 may be removably attachable and detachable to the rest of the helmet 2 in any of the ways discussed above in relation to the modular panels 27, and / or the forehead panel 49, and / or the nose panel 64.

[0094] The mouth panel 70 may comprise fixings 72 for removably attaching the mouth panel 70 to the rest of the helmet 2. For example, this could be to the nose panel 64.

[0095] The mouth panel 70 may comprise a rounded section 74. The mouth panel 70 may be concave such that the rounded section 74 is under the chin strap 14 when worn. The mouth panel 70 may be beneficial for patients with lower face and / or mouth wounds, or those who have undergone cosmetic surgery such as lip fillers.

[0096] In this sense, an improved helmet 2 is provided.

[0097] A corresponding method is also provided. This method can use any of the embodiments of the helmet 2 discussed herein. In this method, the helmet 2 is put on the wearer's (or user's) head. This could be by the wearer themselves of by a third party. The helmet 2 is put on the wearer's head such that the support structure is spaced from their scalp.

[0098] In the method, each of the respective sections of the helmet 2 overlie the corresponding region on the user's head as discussed herein.

[0099] In certain cases, the method can be performed following surgery on the wearer's head. This could, for example, include hair transplant surgery. The protection of the wearer's head is non-therapeutic and non-surgical.

[0100] This method thereby provides protection to the user's head.

Embodiment Construction

[0044]Figures 1 to 4 show various embodiments of a helmet 2 in various orientations. The helmet 2 is shown on the head 4 of a wearer or user. The wearer or user may be an adult or a child, and may be male or female. The helmet 2 may be sized and shaped accordingly, for example based on average dimensions of a head 4. These average dimensions may be selected based on certain characteristics such as sex, age, etc. The wearer's head 4 has a scalp which represents the region of the head 4 where hair typically grows - such as a portion of the head 4 corresponding to the user's cranium. the wearer may have a head wound 6, which requires protection. This head wound 6 could be any type of wound. For example, appearing anywhere on the head, such as the scalp, back of the head, around the eyes, nose, forehead, or mouth. In specific examples, this could be a wound 6 which has resulted from a surgery such as a hair transplant. Of course, the wearer may not have any head wound 6 and may be weari...

Background

[0001] The present application relates to a helmet, and more particularly to a helmet which maintains ventilation around the head of the wearer and facilitates access to wounds such as for the application of medicament or dressings.

[0002] Helmets are well known. Helmets are also used to protect existing injuries during periods of activity and periods of rest. Other helmets with additional, modular, functionalities such as for monitoring sleep, providing communications devices, or providing an apparatus for increased hair growth are also known.

[0003] US9232827B1 discloses a cranial protective helmet having a pair of components made of an exterior hard plastic shell with sufficient flexibility to accommodate the patient with interior cushioning liners conforming to a side of the patient's skull. Each component of the helmet can conform to a side of the patient's head and accommodate an insertion of the patient's head by relative movement with one or more fastener units securing the helmet components to the patient. Openings can be provided to accommodate monitoring instrumentation after a craniectomy operation. The components can be separate or minimally connected to enable a rotational opening. Fastener units can provide a secure connection of the components and an elastic attachment about the patient's head. The apparatus disclosed does not comprise easily attachable and detachable modular panels for facilitating access to different regions of the wearer's head. The cushioning liners also contact the user's head.

[0004] US2012059440 discloses an apparatus for providing increased hair growth and healthier scalp. The apparatus comprises of a swappable-zoned flexible helmet. The flexible helmet device consists of a laser or LED array (from 25 to 300 tiny lasers or 25-300 LEDs) directed at the scalp. The disclosed treatment is subjecting the affected scalp to flexible helmet equipped with the laser or LED array, 3 times a week for a minimum of 20 minutes per session to enable the absorption of laser or light from LED. The apparatus disclosed in this application is not designed for comfort while the user is lying down, for example, with their head on a pillow, and would not facilitate easy access to wounds on the scalp.

[0005] US2011197327A1 discloses a helmet system that enables a user of the helmet system to customize the helmet system according to personal taste, a task at hand, responsibilities within a tactical group (e.g., communications, command, etc.), and / or according to other parameters. The customization of the helmet system may include a customization of electronics modules carried on the helmet system that optionally provide communications, environment detection, health or biometrics monitoring, power, information transmission / reception, information processing, and / or other functionalities. The customization of the helmet system may include a customization of structural components that enable the user to balance the structural protection provided to the user against other considerations. The other considerations may include, for example, weight, form factor, comfort, and / or other considerations. The apparatus of this disclosure is in direct contact with the head of the wearer and therefore may aggravate head wounds.

[0006] Patients of hair transplant procedures may have large areas of their head which need protecting after the procedure. A further challenge is that multiple regions may need protecting, corresponding to donor and treatment regions on different parts of the head. It is important to both protect these regions while also avoiding the helmet itself disturbing them.

[0007] There is therefore a need for a helmet which is readily adaptable to different wound locations and is comfortable for the user during periods of rest.Summary

[0008] A helmet is provided, comprising a shell for protecting a wearer's scalp; and a support structure extending between a first ear connector and a second ear connector configured to engage a wearer's ears in use to wear the helmet, the support structure configured to support the shell in use away from the wearer's scalp when worn. In other words, the shell is spaced from the wearer's scalp. That is, the shell does not contact or touch the wearer's scalp. Such a helmet is useful for protecting the head and / or scalp of the wearer, particularly when the scalp is sore due to injury or recent surgical treatment. The helmet can also protect the hair and / or makeup of the wearer.

[0009] The ear connectors may be biased by the support structure to provide a retaining force on the wearer's head when worn. This helps to retain the helmet on the head without contacting the scalp. Particularly, the ear connectors may be biased towards one another.

[0010] This may be such that the first ear connector and second ear connector are connected to one-another by a horseshoe- or U- shaped piece of material, wherein the spacing between the first and second ear connectors when the helmet is not being worn is less than the spacing between the ears of the wearer. The spacing between the first and second ear connectors may be 0% - 5%, 5% - 10%, or 10% - 25% less than the spacing between the head of the wearer depending on the material from which the horseshoe- or U- shaped piece of material is made. Alternatively, the support structure may define a different shape over the head of the wearer, such that when the helmet is not being worn the spacing between the first and second ear connectors is less than the spacing between the ears of the wearer. The spacing between the first and second ear connectors may be 0% - 5%, 5% - 10%, or 10% - 25% less than the spacing between the head of the wearer.

[0011] The support structure may comprise a grid of struts extending between the first ear connector and the second ear connector. The struts may be made of a rigid plastic, aluminium, stainless steel, other lightweight metal, or carbon fibre. The grid may serve to reduce the weight of the helmet compared to having a solid structure. The grid may further facilitate the use of modular panels, which can be attachable to and detachable from the support structure.

[0012] The shell may comprise modular panels attachable to and detachable from the support structure. These modular panels may be positioned so as to form a near complete covering of the head of the user, or be positioned only to cover specific regions, as dictated by a clinical need. The panels may be detachable to facilitate the easy, localised application of medicament and / or dressings to wounds. Further, the helmet may become more comfortable by removing panels which are not needed, such as, for example, by becoming lighter, and / or by becoming more flexible.

[0013] The modular panels may be constructed from carbon fibre or stainless steel. This could be entirely or at least predominantly (i.e. at least 50%). These are strong materials which will result in the helmet shell having sufficient rigidity, without too much weight.

[0014] The modular panels may be attachable to or positioned between the struts of the support structure. The attachment of the modular panels to the struts may provide an easy attachment mechanism for patients and / or clinicians. In particular, specific panels may connect between specific struts; i.e. panels shaped to cover the side of the head may only fit between struts in this location on the support structure, for example. The panels may further be colour-coded or otherwise identifiable as being positionable between particular struts. The struts may also be colour-coded or otherwise identifiable, such as with numbers. For example, red panels may be attachable between struts which are half red, blue panels attachable between struts which are half blue, and so on, with each strut having at least one colour, number, or other marking, corresponding to the panel attachable on either side of the strut where appropriate.

[0015] The helmet may further comprise connector elements comprising at least one first fixing (which may be a hole) for securing struts to form the grid. The connector elements may allow for easy distribution of the helmet in disassembled form, and easy assembly through insertion of the struts into the connector elements.

[0016] The connector elements may further comprise at least one second fixing for removably attaching modular panels. The connector elements may allow for easy distribution of the helmet in disassembled form, and easy assembly through attachment of the modular panels to the connector elements.

[0017] The modular panels may be attachable to the support structure with captive screws. In other words, the modular panel may retain one or more captive screws for attaching the modular panel to the support structure; the captive screws do not disconnect from the panel in the same manner as the captive screws connect to or disconnect from the support structure. This has the advantage that the screws remain attached to the panel when the panel is removed, and so cannot fall into the wound, or otherwise inside the helmet.

[0018] The shell may extend to the occipital protuberance and at least partially cover the occipital and / or frontal and / or temporal bones. This has the advantage of covering areas which may be used as donor or recipient regions in hair transplant procedures; these areas would therefore benefit from protection from such a helmet as that provided in the present disclosure.

[0019] The shell may extend to the 1 st< cervical vertebrae. This has the advantage of covering areas which may be used as donor or recipient regions in hair transplant procedures; these areas would therefore benefit from protection from such a helmet as that provided in the present disclosure.

[0020] The shell may at least partially cover the parietal bone. This has the advantage of covering areas which may be used as donor or recipient regions in hair transplant procedures; these areas would therefore benefit from protection from such a helmet as that provided in the present disclosure.

[0021] The shell may extend to within 2 cm of the glabella. This has the advantage of covering areas which may be used as donor or recipient regions in hair transplant procedures; these areas would therefore benefit from protection from such a helmet as that provided in the present disclosure.

[0022] The shell may be air permeable. The shell may be formed of a mesh. The mesh structure may comprise a rigid material such as plastic or metal, or a composite material, such as stainless steel, aluminium, or carbon fibre. The mesh structure may be any known form of mesh structure, such as a lock crimp, inter-crimp, stranded, or woven mesh. Alternatively or additionally, the shell may be air permeable through comprising a breathable fabric. Each individual modular panel (or at least some of the modular panels) may be formed of a mesh.

[0023] Breathability may alternatively be achieved by spacing between modular panels. This may be achieved through shaping the panels such that their edges are not contiguous with the support structure and / or the neighbouring modular panel; for example, the modular panel may comprise a concave section between attachment points. Alternatively or additionally, there may be spaces between struts to which no panel is fitted. Alternatively or additionally, the struts of the support structure may have gaps in the middle; with attachment points for neighbouring modular panels either side of the gaps.

[0024] The helmet may further comprise a chin strap. The chin strap may be attached to the first ear connector and the second ear connector for engaging a user's chin in use. The chin strap may further comprise a chin rest. These features may improve the fit of the helmet. The chin strap may be attached to the support structure and / or a modular panel.

[0025] The ear connectors may comprise sub-cups, which are connectable to one another. The sub-cups allow for the helmet to be worn by wearers with different head shapes, as connection of additional sub cups serves to reduce the spacing between the point of the ear cups which engage the wearer's ears (thereby fitting wearers with smaller heads).

[0026] The sub-cups may be connectable through a screw connection. Alternatively or additionally, the sub-cups may be magnetically attachable. The sub-cups may comprise complementary convex and concave surfaces. This may facilitate a quick addition or removal of additional sub-cups, while providing strong attachment between adjacent sub-cups.

[0027] The ear connector may comprise a cushioning element for the comfort of the user, for engaging the wearer's head in use. The cushioning element can help to make the helmet more comfortable and a better fit. The cushioning element may be connected to a sub-cup, or any other part of the ear connector.

[0028] The helmet may further comprise a speaker. The speaker may be removably attached to the ear connector. Each ear connector may comprise a speaker. The speaker may be removably attached to a sub-cup. The speaker may be attached to the ear connector or sub-cup through a screw fit.

[0029] Each ear connector may comprise at least one attachment point for attaching a strap to. The at least one attachment point may be a loop and / or may be spaced around the circumference of the ear connector. The at least one attachment point may be positioned in use between the support structure and the head of the wearer. The at least one attachment point may also be a buckle, adjustor strap, or other such feature as are known in the art. This has the advantage that straps can be run around the head from different attachment points to secure the helmet, thereby allowing the helmet to be secured without a strap contacting a wound.

[0030] The helmet may further comprise at least one strap connectable to the attachment points on the first and second ear connectors. This may provide easy adjustment of the helmet.

[0031] The straps may be made of an elastic material. This may provide a retaining force when stretched over the wearer's head.

[0032] The helmet may further comprise a face shield for protecting at least part of the cheeks and / or nose and / or eyes, and / or forehead, spaced in use from the face of the user when worn.

[0033] The face shield may itself comprise a forehead panel for covering the forehead of the user. The forehead panel may at least partially define an eye opening. The eye opening may be aligned with the wearer's eyes in use.

[0034] The face shield may comprise a nose panel, for covering the nose of the user. The nose panel may at least partially define an eye opening. The eye opening may be aligned with the wearer's eyes in use. The nose panel may be shaped so as to have a central raised portion to maintain spacing between the nose panel and the wearer's nose in use.

[0035] The nose panel and forehead panel may themselves comprise the features of modular panels described herein.

[0036] The forehead panel and nose panel may come pre-formed as a single piece, or may be modular pieces which are individually connectable to the helmet. The use of fewer modular panels where possible may reduce device sterilisation costs / time.

[0037] The forehead panel and nose panel may have overlapping screw holes for attaching to the helmet with the same screw in use. The forehead panel and / or nose panel may be attachable to the helmet through either the ear connectors or the support structure. The face shield may be attachable to the helmet through either the ear connectors or the support structure.

[0038] The face shield may comprise at least one eye opening, aligned with the wearer's eyes in use. As noted above, this can be defined by a combination of the forehead panel and nose panel. Alternatively, the eye opening can be defined on any suitable part of the face shield.

[0039] The helmet may further comprise at least one eye module for covering the at least one eye opening. The eye module may be transparent or translucent for seeing through, or may be opaque.

[0040] The face shield may comprise a mouth panel configured to overlie the user's mouth when worn. Such a mouth panel is useful for protecting the mouth, jaw, and / or lips of the wearer, particularly following an injury or cosmetic intervention, such as lip filler treatment.

[0041] Any of the features described above may be combined with any combination of other features described above.

[0042] Also provided is a method of protecting a user's head comprising: providing the helmet of the present disclosure; and putting the helmet on the user.Brief Description of the Drawings

Detailed Description of the Drawings

[0044] Figures 1 to 4 show various embodiments of a helmet 2 in various orientations. The helmet 2 is shown on the head 4 of a wearer or user. The wearer or user may be an adult or a child, and may be male or female. The helmet 2 may be sized and shaped accordingly, for example based on average dimensions of a head 4. These average dimensions may be selected based on certain characteristics such as sex, age, etc. The wearer's head 4 has a scalp which represents the region of the head 4 where hair typically grows - such as a portion of the head 4 corresponding to the user's cranium. the wearer may have a head wound 6, which requires protection. This head wound 6 could be any type of wound. For example, appearing anywhere on the head, such as the scalp, back of the head, around the eyes, nose, forehead, or mouth. In specific examples, this could be a wound 6 which has resulted from a surgery such as a hair transplant. Of course, the wearer may not have any head wound 6 and may be wearing the helmet 2 for other purposes.

[0045] The helmet 2 comprises a shell 26 for protecting the wearer's scalp. That is, the shell 26 prevents damage to the wearer's scalp. This could be, for example, by acting as a physical barrier blocking or covering at least a portion of the wearer's head.

[0046] The helmet further comprises a support structure 10 extending between a first ear connector 8 and a second ear connector 8. Figures 1 and 2 are side views and so each show one of the ear connectors 8 (specifically the right ear connector from the wearer's perspective). The ear connectors 8 are configured to engage a wearer's ears in use to wear the helmet 2. For example, the first ear connector 8 may contact the wearer's right ear and the second ear connector 8 may contact the user's left ear (or vice-versa). In specific examples, each ear connector 8 may receive the user's respective ear within the ear connector 8. That is, they may be over-ear ear connectors 8. To achieve this, each ear connector 8 may have a cavity or recess which receives the respective ear.

[0047] The support structure 10 is configured to support the shell 26 in use away from the wearer's scalp. That is, when the helmet 2 is worn, with each ear connector 8 engaging with the respective ear, the shell 26 is spaced from the wearer's scalp. In other words, the shell 26 is not contacting the wearer's scalp. It may also be the case that the support structure 10 itself is not contacting the wearer's scalp. That is, it may be only the ear connectors 8 which contact the user's head 4. This allows the shell 26 to protect the wearer's head (specifically for example the scalp) without being in direct contact therewith.

[0048] For example, the support structure 10 may be arranged such that the shell 26 is always at least 0.5 centimetres from the wearer's scalp, preferably at least 1 centimetre or 2 centimetres from the wearer's scalp.

[0049] In supporting the shell 26 in use away from the wearer's scalp, the helmet 2 does not apply any pressure onto the scalp. Particularly, when the wearer is laying down or otherwise resting the head 4 on a surface. This can help prevent the head wound 6 from being aggravated. Likewise, this could protect any hair styles or make-up which had been applied to the user from damage.

[0050] The shell 26 may be air permeable, such as through comprising air permeable material and / or a mesh structure. The mesh structure may comprise a rigid material such as plastic or metal, or a composite material, such as stainless steel, aluminium, or carbon fibre. The mesh structure may be any known form of mesh structure, such as a lock crimp, inter-crimp, stranded, or woven mesh. Alternatively or additionally, the shell may be air permeable through comprising a breathable fabric material. Breathability may additionally or alternatively be achieved through shaping the modular panels 27 such that their edges are not contiguous with the support structure 10 and / or the neighbouring modular panel 27; for example, the modular panel 27 may comprise a concave section between connector elements 24, wherein the edges of the modular panel 27 are curved away from the neighbouring strut 11. Alternatively or additionally, there may be spaces between struts 11 to which no modular panel 27 is fitted. Alternatively or additionally, the struts 11 of the support structure 10 may have gaps in the middle; with attachment points for neighbouring modular panels 27 either side of the gaps.

[0051] Figure 1 further shows how the ear connectors 8 may each comprise one or more strap fixings 16 (such as a loop, or other attachment point). These strap fixings 16 may specifically be provided on an ear cup of the ear connector 8. A strap 12 may be attached to these strap fixings 16, such that the strap 12 extends between the first ear connector 8 and the second ear connector 8. The strap 12 being for at least partially (further) securing the helmet 2 on the head 4 of the wearer. This strap 12 can be designated as a head strap 12 if required to differentiate it from other straps of the helmet 2. In certain cases, there may be multiple straps 12 extending between strap fixings 16. The head strap 12 may be made from an elastic material. In certain cases, the length of the head strap 12 may be adjustable.

[0052] The helmet 2, may comprise a chin strap 14 for engaging the user's chin in use. The chin strap 14 may be in addition to, or an alternative to, the head strap 12 The chin strap 14 may at least partially (further) secure the helmet 2 on the head 4 of the wearer. The chin strap 14 may be secured to a loop, attachment point or chin strap fixing 18 on the ear connectors 8. This chin strap fixing 18 may be the same as the strap fixings 16 for the head straps 12. The chin strap 14 may be made from an elastic material. The chin strap 14 may be the same as the head strap 12 - possibly with a different length. The length of the chin strap 14 may be adjustable. The chin strap 14 may further comprise a chin rest element 66 (such as shown in the helmet 2 of Figure 8c).

[0053] The helmet 2, may comprise a face shield 20. That is, a part of the helmet 2 which covers the wearer's face. An example of such a helmet 2 is shown in the embodiment of Figure 2. Unless otherwise expressly stated to the contrary, the embodiment of Figure 2 is the same as that of Figure 1. Any features discussed in relation to the embodiment of Figure 1 are equally applicable to the embodiment of Figure 2, and vice-versa.

[0054] The face shield 20 may cover all or part of the cheeks and / or eyes and / or nose, and / or forehead of the wearer. Again, in use the face shield 20 may be spaced from these parts of the wearer's face. The face shield 20 may be supported by the support structure 10 of the helmet 2.

[0055] An example face shield 20 is shown in Figures 8a to 8c and will be discussed in more detail below. In brief, the face shield 20 may comprise a forehead panel 49 or module. This forehead panel 49 is configured to overlie a user's forehead in use.

[0056] The face shield 20 may additionally or alternatively comprise a nose panel 64 or panel. The nose panel 64 is configured to overlie a user's nose in use and protect the nose. The nose panel 64 may contact the user's nose when the helmet 2 is worn. Alternatively, the nose panel 64 may be spaced from the user's nose. The nose panel 64 may be shaped so as to have a central raised portion to maintain spacing between the nose panel 64 and the wearer's nose in use.

[0057] The shell 26 may extend to the user's occipital protuberance. That is, the shell 26 may be configured to overlie the occipital protuberance in use when worn.

[0058] The shell 26 may at least partially (or entirely) cover one or more of the occipital, and / or frontal, and / or temporal bones. In certain cases the shell 26 may extend to the 1 st< cervical vertebrae (such that in use the helmet 2 overlies the 1 st< cervical vertebrae). The shell 26 may at least partially (or entirely) cover the parietal bone.

[0059] In certain examples the shell 26 may extend to within 2 cm of the glabella. The addition of the face shield 20 can then extend beyond the glabella.

[0060] Any of these extents of the shell 26, and bones overlayed in use, may be individually incorporated as appropriate for a particular helmet 2.

[0061] In certain cases, the shell 26 may be formed of a plurality of modular panels 27. Figure 3 shows a rear view of a helmet 2 in accordance with such an embodiment. Unless otherwise expressly stated to the contrary, the embodiment of Figure 3 is the same as that of Figures 1 and / or 2. Any features discussed in relation to the embodiments of Figure 1 and / or 2 are equally applicable to the embodiment of Figure 3, and vice-versa.

[0062] The helmet 2 comprises a shell 26. The shell 26 may comprise modular panels 27. The modular panels 27 may be removably attachable and detachable from the support structure 10. That is, without damaging the shell 26. Particularly this is to the support structure 10. The modular panels 27 can be selectively attached and detached from the support structure 10 to customise the helmet 2. For example, there may be one or more different types of modular panels 27 which can be attached to the helmet 2 so as to overlie different parts of the wearer's head. The modular panels 27 (or at least some of the modular panels 27) may be air permeable, such as comprising a mesh. Figure 3 shows how the modular panels 27 may be arranged in an array about the shell 26. In certain cases, the user may choose to selectively leave areas on the shell without any modular panel(s) 27.

[0063] The modular panels 27 may connect between specific struts 11; i.e. modular panels 27 shaped to cover the side of the head may only fit between struts 11 in this location on the support structure 10, for example. The modular panels 27 may further be colour-coded or otherwise identifiable as being positionable between particular struts 11. The struts 11 may also be colour-coded or otherwise identifiable, such as with numbers. For example, red modular panels 27 may be attachable between struts 11 which are half red, blue modular panels 27 attachable between struts 11 which are half blue, and so on, with each strut 11 having at least one colour, number, or other marking, corresponding to the modular panel 27 attachable on either side of the strut 11 where appropriate. Alternatively, only the screw holes on each panel and strut may be colour-coded, or otherwise identifiable, such as with numbers. Alternatively or additionally, screw holes on the connector elements 24 may be colour-coded, or otherwise identifiable, such as with numbers.

[0064] The struts 11 may be connected to one another by connector elements 24. Connecting the struts 11 in this manner can form the support structure 10. For example, the connector elements 24 may comprise at least one first fixing 32 such as recesses or holes for receiving adjacent and / or intersecting struts 11.

[0065] The support structure 10 may comprise a grid of struts 11 extending between the first ear connector 8 and the second ear connector 8. An example of such a grid of struts 11 is shown in Figures 6a and 6b. The struts 11 may be elongate bars or plates, with gaps in between. The modular panels 27 can then be attached to the struts 11 to span these gaps. In other words the modular panels 27 may be positioned between the struts 11.

[0066] The modular panels 27 may be attachable to the support structure 10 in any suitable manner. This could include an interference or snap fit. However, in some cases a fastener may be used to attach the modular panels 27 to the support structure 10. In a particular example, the modular panels 27 are attachable to the support structure 10 with captive screws. The screws are captive in that they are retained by a component of the helmet 2 and cannot readily be removed from that component. The captive screws may not disconnect from the modular panel 27 in the same manner as the captive screws connect to or disconnect from the support structure 10. For example, each modular panel 27 may retain one or more captive screws. The support structure 10 (such as the connector elements 24) may then comprise corresponding threaded holes. Of course, the alternative is also possible with the support structure 10 (such as the connector elements 24) retaining the captive screws and the threaded holes being in the modular panels. To attach the modular panel 27 to the support structure 10 the captive screw is received in the threaded hole and turned to engage the captive screw with the threaded hole.

[0067] The shell 26 may comprise flat and / or curved modular panels 27. In certain cases, there may be a mixture of flat modular panels 27 and curved modular panels 27, used at different parts of the helmet 2. In general, the shell 26 needs to conform to the user's head and the modular panels 27 can be selected accordingly.

[0068] The shell 26 may be predominantly (or entirely) constructed from carbon fibre or stainless steel. In other words, the shell 26 may consist essentially of (or indeed consist of) carbon fibre or stainless steel. Specifically, the modular panels 27 may be constructed from (consisting essentially of or consisting of) carbon fibre or stainless steel. In certain cases, the struts 11 may themselves be constructed from (consisting essentially of or consisting of) carbon fibre or stainless steel. The struts and / or modular panels may alternatively be constructed from (consisting essentially of, or indeed consisting of) plastic or metal, such as aluminium.

[0069] Figure 4 shows a frontal plane cross-section of a helmet 2 being worn in use by a wearer. This may be the helmet 2 of any of the embodiments discussed herein. Again, any features discussed in relation to Figure 4 are equally applicable to any of the embodiments. The cross-section is applied to the helmet 2 and not to the user's head which is shown in a schematic front view.

[0070] The ear connectors 8 shown in Figure 4 are over-ear ear connectors 8. That is, the user's ears are received in the ear connectors 8, such as in a cavity or recess thereof. The ear connectors 8 may be biased to provide a retaining force on the wearer's head 4 when worn. Specifically, this could be by being biased towards one another when worn. This biasing can be provided by the support structure 10.

[0071] The ear connectors 8 may provide said retaining force through being connected to one-another by an approximately horseshoe- or U-shaped piece of material 100, forming part of the support structure 10. For example, the spacing between the first and second ear connectors 8 when the helmet 2 is not being worn (also called "at rest") is less than the spacing between the ears of the wearer. The spacing between the first and second ear connectors 8 when the helmet is not being worn may be 0% to 5%, 5% to 10%, or 10% to 25% less than the spacing between the ear connectors when the helmet is worn on head of the wearer depending on the material from which the horseshoe- or U- shaped piece of material 100 is made. This could be determined based on standard head sizes. In certain cases, there may be different helmets selectable by size and / or characteristics (sex, age, etc.) of the wearer. The spacing between the ear connectors 8 may be adjustable. For example, by having each ear connector 8 on an extendable section extending from the horseshoe- or U- shaped piece of material 100.

[0072] Alternatively, the support structure 10 may define a different, but functionally equivalent shape over the head 4 of the wearer, such that when the helmet 2 is not being worn, the spacing between the ear connectors is less than the spacing between the ears of the wearer. The spacing between the first and second ear connectors when the helmet is not being worn may be 0% to 5%, 5% to 10%, or 10% to 25% less than the spacing between the ear connectors when the helmet is worn on the head 4 of the wearer.

[0073] When worn on the user's head, the ear connectors 8 are biased towards one another - effectively gripping onto the user's head 4. This can then help to retain the helmet 2 on the user's head. This engagement can help to space the shell 26 from the user's scalp since contact with the scalp may not be necessary to locate the helmet 2.

[0074] Figure 5 shows an example of an ear connector 8 on the head 4 of a wearer, engaging the ears of the wearer. This ear connector 8 can be used with any of the embodiments discussed herein. The ear connector may comprise multiple fixings, 16, 18, 28, between the support structure 10 and the head 4 of the wearer (i.e. the medial or inner side of the support structure), such as strap fixings 16, chin strap fixings 18, or other medial fixings 28. That is, the support structure 10 is outward (with respect to the centre of the helmet 2, or the user's head) of the fixings 16, 18, 28. The fixings 16, 18, 28 are suitable for connecting straps 12, 14 for (further) securing the helmet 2 on the head 4 of the wearer in use. This can include, for example, the head strap 12 and / or chin strap 14 discussed above. The straps 12, 14 are selectively attachable to the fixings 16, 18, 28.

[0075] Multiple fixings 16, 18, 28 may facilitate the helmet 2 being secured with straps in a way that does not interfere with or contact the wound 6, for a variety of wound positions. That is, an appropriate combination of fixings 16, 18, 28 can be selected based on the location of the head wound 6. For example, this may be so that the head strap 12 does not overlie any head wound 6 in use when the helmet 2 is worn. Lateral fixings 30 may be positioned on the lateral (i.e. outer) side of the support structure 10, for further straps 12, 14 and / or securing additional devices to the helmet 2.

[0076] As noted above, Figure 6a shows an example of a grid of struts 11 forming part of the support structure 10. The struts 11 may be connected by connector elements 24. The connector elements 24 may comprise at least one first fixing 32, such as a hole for securing the struts 11 in the support structure 10. The connector elements 24 may further comprise at least one second fixing 33, for removably attaching modular panels 27. The at least one second fixing 33 may be a threaded hole. Additionally or alternatively, the at least one second fixing 33 may be a press stud. The at least one second fixing 33 may be transverse, such as substantially perpendicular or perpendicular, to the hole 32.

[0077] The connector element 24 may comprise an inner element and an outer element, wherein the inner element in use is closer to the wearer's skull when worn, and the outer element is further from the wearer's skull when worn than the inner element. The inner element and outer element may separately or collectively define one of more holes 32 configured to fit a strut 11. The inner element and outer element may be connected by a tightening mechanism, configured to lock the strut 11 in place. The tightening mechanism may be screws through both the inner and outer elements. The connector element 24 may comprise a first set of screw holes configured to tighten together the inner element and outer element together, thereby locking a strut 11 into the element. The first set of screw holes could additionally function as the at least one second fixing 33 for removably attaching modular panels 27. The set of screw holes may be on the outer element.

[0078] Of course, alternative connector elements 24 are possible, such as those where the strut 11 is received in a bore and held in place via an interference fit. This may or may not have the inner and outer element discussed above.

[0079] Figures 7a to 7c shows an example of an ear connector 8. This ear connector 8 can be used with any of the embodiments discussed herein. The ear connector 8 of Figure 7 comprises one or more sub-cups 38. This sub-cup 38 may connect to the support structure 10 such as through a sub-cup fixing 34. For example, this may be with the horseshoe- or U- shaped piece of material 100. Figure 7a shows an example with two sub-cups 38. However there may be more or fewer sub-cups 38.

[0080] A cushioning element 36 is attached to the innermost sub-cup 38, for contacting and / or receiving the user's ear in use. The cushioning element 36 can provide a comfortable fit around the ears of the user.

[0081] In certain examples, the cushioning element may comprise a foam - particularly a solid foam.

[0082] Each sub-cup 38 may be coupleable to additional sub-cups 38 - such as the two sub-cups 38 shown in Figure 7a. The connection between sub-cups 38 may be through a screw or pin connection 40, an interference fit, a snap fit, or any other type of connection. The sub-cup 38 (particularly the outermost sub-cup 38) may comprise a fixing 34 for the support structure 10 and / or horseshoe- or U- shaped piece of material 100. Each sub-cup 38 may be identical. However, in certain cases there may be an outermost sub-cup 38 which is fixed to the support structure 10. Additional sub-cups 38 which are different to the outermost sub-cups 38 can then be attached to the outermost sub-cups 38. This can reduce the spacing between the ear connectors 8, for example to provide the biasing force discussed above.

[0083] The ear connector 8 may comprise a recess, cavity or void 44, 48 for receiving the ears of the wearer. In use, the recess or cavity 44, 48 can receive the ear such that the ear connector 8 substantially (or entirely) surrounds the ear of the user. The recess or cavity 44, 48 which may be a through-hole 44, or a closed cavity 48. In certain cases, the recess or cavity 44, 48 may be designed to receive a complementary extrusion 46 on a further sub-cup 38. The sub-cups 38 may comprise complementary convex and concave surfaces. This can then lead to an interference fit between the sub-cups 38 to attach the sub-cups 38 to one another. Alternatively or additionally, the sub-cups 38 may be magnetically attachable to one another. This could include, for example, one or more magnets and / or magnetic regions on each sub-cup 38.

[0084] The helmet 2 may further comprise one or more speakers. Specifically there may be two speakers - one for each ear connector 8. These speakers can be permanently attached to the respective ear connector 8. However, in particular examples the speakers can be removably attachable and detachable to the ear connectors 8. For example, the ear connectors 8 (such as the sub-cups 38) may comprise one or more speaker fixings 42 which the speaker attaches to. This could be a threaded hole, or could be an interference fit or snap fit. The speakers can play sound in the ear connectors 8. The or each speaker may comprise a suitable audio driver, or have one connected thereto. These speakers can be incorporated into any of the embodiments discussed herein.

[0085] As noted above, Figures 8a to 8c show a possible configuration of a face shield 20 which can be used with any of the embodiments discussed herein. Figure 8a shows a forehead panel 49 for covering at least part of the glabella of the wearer. The forehead panel 49 may cover the entirety of the glabella of the wearer. The forehead panel 49 may be attached to the helmet 2, for example to the support structure 10.

[0086] The forehead panel 49 may at least partially define an edge of an opening 52. In use this edge 52 can be aligned with the wearer's eyes. This opening can be for allowing the wearer to see when wearing the helmet 2. The forehead panel 49 may be removably attachable and detachable to the rest of the helmet 2 in any of the ways discussed above in relation to the modular panels 27. In certain examples, the forehead panel 49 may comprise one or more fastener holes 54, 56 for receiving a fastener, such as a screw. There may be one or more captive screws retained by the forehead panel 49 for engaging threaded holes of the support structure 10 (or vice-versa). Of course other attachment methods such as interference fits or snap fits could be used.

[0087] Figure 8b shows a nose panel or panel 64, for covering at least part of the nose of the wearer. Collectively the forehead panel 49 and nose panel 64 may form the face shield 20. The nose panel 64 may be attachable and detachable to the helmet 2. This could be to the support structure 10, either directly or indirectly. For example, the nose panel 64 could connect to the forehead panel 49, and the forehead panel 49 then connects to the support structure 10 (or vice-versa). The nose panel 64 may at least partially define an edge of an opening 62. In use, this edge 62 can be aligned with a wearer's eyes. This opening can be for allowing the wearer to see when wearing the helmet. The nose panel 64 may comprise a raised portion 65 for maintaining a gap between the nose panel 64 and the nose of the wearer in use.

[0088] Collectively the edge 52 of the forehead panel 49 and the edge 62 of the nose panel 64 can define an eye opening 68 (or at least part of an eye opening 68). This eye opening 52 aligned with the user's eyes to allow the user to see out when wearing the helmet 2. The helmet 2 may further comprise an eye module connectable to and suitable for covering the eye opening 68. This eye module can be formed of a transparent or translucent material to allow the user to see through the eye opening 68. Alternatively, an opaque eye module may be provided. For example, the user could select an opaque eye module to sleep wearing the helmet 2. The eye module may be selectively attachable so that a transparent / translucent eye module is used when the user is wearing the helmet 2 when not sleeping, and an opaque eye module is used when the user is sleeping wearing the helmet 2.

[0089] The nose panel 64 may be removably attachable and detachable to the rest of the helmet 2 in any of the ways discussed above in relation to the modular panels 27, and / or the forehead panel 49. In certain examples, the forehead panel 49 may comprise one or more fastener holes 58, 60 for receiving a fastener, such as a screw. There may be one or more captive screws retained by the nose panel 64 for engaging threaded holes of the support structure 10 or the forehead panel 49 (or vice-versa). Of course other attachment methods such as interference fits or snap fits could be used.

[0090] The forehead panel 49 and nose panel 64 may be attachable to one another through fastener holes 54, 56, 58, 60 (such as screw holes). The forehead panel 49 and nose panel 64 may be pre-formed together as a single piece face shield 20.

[0091] In certain cases, the forehead panel and / or nose panel may be connectable to the ear connectors 8, as shown in Figure 8c. This could be a direct connection, such as via one or more fasteners, an interference fit and / or a snap fit.

[0092] The helmet 2 may further comprise a mouth panel 70 (or mouth shield), shown in Figures 9a and 9b. The mouth panel 70 being arranged to overlie, in use, the user's mouth. The mouth panel 70 is suitable for protecting the user's mouth.

[0093] While these Figures show the mouth panel 70 in an example with the forehead panel 49 and nose panel 64, it is appreciated that this is not necessarily the case and each can be provided independently. The mouth panel 70 may be removably attachable and detachable to the rest of the helmet 2 in any of the ways discussed above in relation to the modular panels 27, and / or the forehead panel 49, and / or the nose panel 64.

[0094] The mouth panel 70 may comprise fixings 72 for removably attaching the mouth panel 70 to the rest of the helmet 2. For example, this could be to the nose panel 64.

[0095] The mouth panel 70 may comprise a rounded section 74. The mouth panel 70 may be concave such that the rounded section 74 is under the chin strap 14 when worn. The mouth panel 70 may be beneficial for patients with lower face and / or mouth wounds, or those who have undergone cosmetic surgery such as lip fillers.

[0096] In this sense, an improved helmet 2 is provided.

[0097] A corresponding method is also provided. This method can use any of the embodiments of the helmet 2 discussed herein. In this method, the helmet 2 is put on the wearer's (or user's) head. This could be by the wearer themselves of by a third party. The helmet 2 is put on the wearer's head such that the support structure is spaced from their scalp.

[0098] In the method, each of the respective sections of the helmet 2 overlie the corresponding region on the user's head as discussed herein.

[0099] In certain cases, the method can be performed following surgery on the wearer's head. This could, for example, include hair transplant surgery. The protection of the wearer's head is non-therapeutic and non-surgical.

[0100] This method thereby provides protection to the user's head.
