Description

A patient may be confined to a bed for periods of time when staying in a hospital, care facility or mental health facility. For some patients, it can be beneficial for the patient to be positioned close to the floor. For example, if the patient is prone to falls, then positioning the bed close to the floor can help to reduce the impact, and the chance of injury, if the patient falls from the bed. Additionally, if the patient has restricted mobility, then positioning the bed close to the floor can assist with getting the patient into and out of bed. To this end, it can be beneficial for patients to use a “box bed”. Box beds are simple constructions, comprising a frame having a base that is positioned directly on the floor, and a mattress positioned on the base of the frame. These box beds provide a simple solution to safely accommodating a patient close to the floor, to reduce the risk of injury. However, box beds typically provide no versatility for the caregiver. The simplicity of the design of a box bed means that the features in other types of hospital beds, which allow the patient’s position to be adjusted by the caregiver, cannot be included. The simplicity of a box bed also means that the position of the bed itself cannot be adjusted. This can be useful either with the patient in the bed, for transportation purposes, or when the bed is empty, to relocate the bed. Known hospital beds typically include a frame that raises a deck from the floor. In use, the deck may be used to support a mattress, upon which the patient is positioned. This type of hospital bed may be provided with other features, which allow the caregiver to adjust the position of the patient. In particular, the frame of typical hospital beds may be provided with a plurality of wheels or castors, which can be used to manoeuvre the bed across a surface. Typical hospital beds may also include features allowing parts of the deck to be selectively raised and lowered, to improve the treatment and comfort of the patient. For example, the head portion of the hospital bed could be raised, while the body and foot portions remain flat. Likewise, the foot portion may also be raised. These features can be beneficial, to allow the caregiver to move the patient across the room, or to adjust the patient’s position on the bed to improve their comfort or treatment. However, these features are not included in known box beds. Although they provide improved versatility, the type of known hospital beds described above also has various disadvantages. For example, since the patient is raised from the floor, the impact of falls will be greater. Additionally, some features of typical hospital beds can reduce patient safety in certain scenarios. In particular, in certain settings, such as if the bed is used by a mental health patient, there are additional concerns for the safety of the patient. A typical hospital bed may contain many ligature points. In particular, the headboard, the footboard, the side rails and the frame under the deck may provide various ligature points. The frame under the deck may also include various metal fixtures, or cables for supplying power, which can be accessed by the patient. These ligature points, cables and metal fixtures may serve as a safety risk, particularly when the hospital bed is used by a patient suffering with poor mental health. Therefore, although known hospital beds provide the benefits of improved versatility of the patient’s position, they may be inappropriate to use for some patients, due to the ligature points, cables and metal fixtures. An aim of the present invention is to provide an improved bed, which may be used in hospitals, care facilities or mental health facilities. BRIEF DESCRIPTION OF THE INVENTION There is provided a bed comprising: a platform for supporting a patient; a frame configured to support the platform; and one or more anti-intrusion panels between the platform and the frame, wherein the anti-intrusion panels are configured to prevent the patient from accessing the frame. The bed may comprise four anti-intrusion panels. The anti-intrusion panels may be attached to the frame using security screws. The platform may comprise a plurality of platform sections, wherein the bed is configured to enable at least one of the platform sections to be raised relative to the or each other platform section. The bed may further comprise a plurality of walls, wherein each wall is configured to abut at least one edge of the platform. The frame may enable movement of the platform between a first position and a second position, wherein, when in the second position, a part of the or each wall is positioned to block access between the wall and an external support surface. The walls may comprise a headboard, a footboard and two side walls. At least one of the walls may be removeable from the bed. At least one of the side walls may comprise a plurality of side panels. Each side panel may be independently moveable and / or removeable from the bed. At least one side panel may comprise a pivotable latch that is configured to prevent removal of the side panel if the bed its lowest position. The frame may comprise a plurality of castors. The bed may further comprise an actuation mechanism that is configured to raise and / or lower the platform relative to the castors. There is also provided a kit comprising a bed as described herein and a handset that is configured to wirelessly control the position of the platform. The platform may comprise a plurality of platform sections, wherein the handset is configured to control the position of at least one of the platform sections relative to the other platform sections. The handset may be configured to control the height of the platform. BRIEF DESCRIPTION OF THE FIGURES In order that the present disclosure may be more readily understood, preferable embodiments thereof will now be described, by way of example only, with reference to the accompanying drawings, in which: FIGURE 1 is a perspective view of a bed; FIGURE 2 is a top view of the bed of Figure 1; FIGURE 3 is an exploded view of the bed of Figure 2, with a headboard, footboard and side walls removed, and with anti-intrusion panels shown at the top of the Figure; FIGURE 4 is a top view of the bed of Figure 1, with platform sections removed; FIGURE 5 is a perspective view of the bed of Figure 1, with an alternative version of the headboard, footboard and side walls; FIGURE 6 is a side view of the bed of Figure 5; FIGURE 7A is a perspective view of the bed of Figure 1, in a lowered position, with the second version of the side walls; FIGURE 7B is a perspective view of the bed of Figure 7A, in the lowered position, with the second version of the headboard and footboard; FIGURE 8A is a side view of a portion of the side wall of the bed of Figure 7B, in a first position; and FIGURE 8B is a side view of the portion of the side wall of Figure 8A, in a second position. DETAILED DESCRIPTION OF THE DISCLOSURE Referring to Figure 1, there is shown a bed 100. The bed 100 has a first end 100a and a second end 100b. In the example shown, the first end 100a is a head end and the second end 100b is a foot end. The bed 100 includes a frame 110 and a sleeping deck or platform 130. In use, the platform 130 may be used to support a mattress (not shown), to improve the comfort of a patient. The platform 130 or the mattress forms a surface on which a patient can be positioned. The bed 100 may include one or more walls or rails, which surround at least one edge of the platform 130. In the example shown, the bed 100 includes four walls, including a headboard 101, a footboard 102 and two side walls 103, 104. The headboard 101, footboard 102 and side walls 103, 104 may be used to prevent a patient resting on the platform 130 or mattress from falling. Using walls, rather than rails, may be preferable, to reduce the ligature points of the bed 100. The frame 110 is used to support the platform 130, and may be provided with other features to adjust the position of the bed 100. For example, the frame 110 may comprise wheels or castors 111. It will be appreciated that any suitable ground engaging device may be selected. The castors 111 may allow a caregiver to move the bed 100 around the room. The castors 111 are connected to the platform 130 by support members 112. In the example shown, each support member 112 is collapsible, in order to allow the platform 130 to be raised and lowered relative to the castors 111. In particular, each support member 112 comprises telescopic struts that enable the support member 112 to collapse. The bed 100 may be configured to raise and / or lower one or more sections of the platform 130. The platform 130 may be formed of a plurality of sections, including, for example, a head platform section 131, a foot platform section 134, and at least one body platform section 132, 133. In the example shown, the platform 130 comprises a head platform section 131, two body platform sections 132, 133 and a foot platform section 134, although it will be appreciated the platform 130 may include any suitable number of platform sections. The illustrated head platform section 131 is positioned adjacent the first end 100a of the bed, and the foot platform section 134 is positioned adjacent the second end 100b of the bed 100. The body platform sections 132, 133 are positioned between the head platform section 131 and the foot platform section 134. The bed 100 may be configured to enable the head and / or foot platform sections 131, 134, to be selectively raised and / or lowered relative to the body platform sections 132, 133. These features may be advantageous, to improve the versatility of the bed. The bed 100 may be provided with one or more actuators, such as a raise / lower mechanism, which can be used to control the configuration of the bed 100. For example, the frame 110 may include one or more actuators that are configured to raise and / or lower the position of each platform section 131-134 relative to the other platform sections 131-134. The bed 100 may also include one or more actuators that are configured to raise and / or lower the position of the platform 130 relative to the castors 110. The bed 100 may also be provided with one or more batteries or means for connecting to a power source, in order to provide power to the or each actuator. For example, the frame 110 may include a battery engagement formation. Referring to Figures 2 and 3, the bed 100 may also comprise one or more anti-intrusion panels 120. Figure 3 shows an exploded view of the bed of Figures 1 and 2, with the headboard, footboard and side walls removed. In Figure 3, the anti-intrusion panels 120 are illustrated above the platform 130, so that the shapes of the anti-intrusion panels 120 are clearly shown. In use, the anti-intrusion panels 120 may be positioned around the perimeter of the bed 100. Each antiintrusion panel 120 may be positioned between the platform 130 and the frame 110. In the example shown, the bed 100 comprises four anti-intrusion panels 120a, 120b, 120c, 120d. It will be appreciated that the bed 100 could include any suitable number of anti-intrusion panels. For example, the bed 100 could include a single anti-intrusion panel that substantially surrounds the perimeter of the bed 100. The anti-intrusion panels 120 are configured to prevent a patient from reaching through any gaps between the headboard, footboard or side walls and the platform sections, or gaps between the platform sections, in order to access the frame. For example, in the illustrated example, one antiintrusion panel is configured to block the gap between the headboard 101 and the head platform portion 131, another anti-intrusion panel 120b is configured to block the gap between the footboard 102 and the foot platform section 134, and two anti-intrusion panels 120c, 120d are configured to block the gaps between the platform sections 131, 132, 133, 134 and the side walls 103, 104. However, it will be appreciated that anti-intrusion panels could be provided in order to block any gap between the other components of the bed 100. The anti-intrusion panels 120 may be shaped so as to allow the platform sections 131, 132, 133, 134 to be attached to portions of the frame 110 that are configured to raise and / or lower the platform sections 131. 132. 133, 134. For example, the anti-intrusion panels may contain cut-out sections that allow a direct attachment between the platform sections 131, 132, 133, 134 and the frame 110. Each anti-intrusion panel 120 may be positioned between the platform 130 and the frame 110. In this way, the anti-intrusion panels prevent a patient from reaching through any gaps between the headboard, footboard or side walls and the platform sections, or gaps between the platform sections, in order to access the frame. In prior art beds, in which no anti-intrusion panels are provided, the patient could reach their hand between the side wall and the platform, for example, in order to access the frame. The frame 110 may contain metal fixtures, cables, batteries or ligature points, which could be dangerous if accessed by some patients. For example, for patients with poor mental health, it is particularly advantageous to prevent the patient from accessing the frame (including any metal fixtures, cables, batteries or ligature points), by way of anti-intrusion panels. The anti-intrusion panels 120 may be attached to the frame 110 by any suitable attachment means. In the illustrated example, the anti-intrusion panels 120 are attached to the frame 110 by security screws 125. Security screws are screws that have screw heads having an unusual indentation. This unusual indentation means that the security screws can only be removed by using a tool with a compatible shape. For example, the security screws may have “snake-eye” shaped indentations. In other words, the security screws may include two circular indentations. Alternatively, the security screws may be a “torx screw”. In other words, the security screw may include a star shaped indentation. The use of security screws 125 reduces the chance of a patient removing the anti-intrusion panels 120. In particular, if conventional screws are used, then the patient could use a screwdriver or another simple tool to remove the anti-intrusion panels 120, and gain access to the frame 110. Security screws 125 can only be removed using a specific tool, making it difficult for a patient to remove the anti-intrusion panels 120 and gain access to the frame 110, thereby making the bed 100 safer. The platform 130 may also be attached frame 110 by security screws 125. Likewise, the use of security screws 125 to attach the platform 130 to the frame 110 may improve the safety of the bed 100 by preventing unauthorised persons, such as patients, from removing the platform. The anti-intrusion panels 120 may be manufactured from a material that allows for some flexion. For example, the anti-intrusion panels may be manufactured from polypropylene. The use of a material that is not brittle may be advantageous, because this would make it harder for a patient to snap an anti-intrusion panel. Additionally, the use of polypropylene may be particularly advantageous because polypropylene would be particularly difficult for a patient to snap, and, if snapped, the anti-intrusion panel would not be left with a sharp edge that could injure the patient. As explained above, the frame 110 may be provided with one or more batteries or means for connecting to a power source, in order to provide power to any actuators. If the bed 100 is provided with anti-intrusion panels 120, then the anti-intrusion panels 120 could prevent access to the batteries or means for connecting to power. To enable a user such as a caregiver to access batteries or means for connecting to power, if necessary, the anti-intrusion panels 120 may be provided with one or more access points 121. The access points 121 may enable a caregiver to connect the bed to a power supply, or to replace one or more batteries in the bed 100. For example, the head platform section 131 could be raised by the caregiver, and the caregiver could reach through the access point 121 in the anti-intrusion panels 120, in order to access batteries or connect the bed to a power source. Alternatively, if the patient was not in the bed 100, for example, then the batteries or connection to a power source could be accessed by the caregiver from below, i.e. from underneath the frame 110. The bed 100 may be operable by an external handset. For example, the bed may be configured to communicate with an external handset via Bluetooth. The handset may be configured to raise and / or lower the platform 130 relative to the castors 111, and / or to raise and / or lower one or more sections of the platform. This may be advantageous, to enable the caregiver to adjust the position of the patient remotely, without relying on the physical strength of the caregiver and without a cable extending between the handset and the bed 100. This may be particularly advantageous if the bed 100 includes anti-intrusion panels 120 containing one or more access points 121 that enable batteries or means for connecting to a power source to be reached. In the example shown, the bed 100 contains a head platform section 131 that, when in a raised position, provides access to a battery or means for connecting to a power source, by way of an access point 121 in an antiintrusion panel 120c. Therefore, it may be advantageous for the raising of the head platform section 131 to be controllable by an external handset. This would allow the external handset to be carried by the caregiver, so that the caregiver is able to raise the head platform section 131, in order to connect the bed 100 to a power supply or to replace one or more batteries in the bed. In this way, the patient would be unable to move the head platform section 131 in order to access the batteries or means for connecting to a power supply, without access to the external handset. It will be appreciated that the access point and / or batteries and / or means for connecting to a power supply could be positioned in any suitable location of the bed. For example, the access point could be provided in an anti-intrusion panel that is positioned under a foot platform section. A plurality of access points may be provided, however the fewest access points possible is desirable. As mentioned above, the illustrated example includes a headboard 101, a footboard 102 and two side walls 103, 104. The headboard 101, footboard 102 and sidewalls 103, 104 may be positioned so that any actuators of the frame 110 do not extend below the bottom of the headboard 101, footboard 102 or side walls 103, 104, if the bed 100 is viewed in a side view, as shown in Figure 6. The bed 100 may also be configured to be raised and lowered, so that the platform 130 is lowered relative to the castors 111. Figures 7 A and 7B show the platform 130 lowered to its lowest position, such that the platform is adjacent the floor when in use. As illustrated in Figures 7A and 7B, the headboard 101, footboard 102 and sidewalls 103, 104 may be configured to contact a surface, e.g. the ground, when the bed 100 is in its lowest position. In this way, and as shown in Figures 7A and 7B, the bed 100 may form a box bed. The bed 100 forming a box bed may be advantageous. For example, when in the lowest position, the components of the frame 110 such as the castors and actuators, as well as any batteries and cables may be inaccessible to the patient, whether the patient is in or out of the bed, because they are positioned between the platform 130, the anti-intrusion panels 120, the headboard 101, the footboard 102, the side walls 103, 104 and the ground. When in the lowest position, the side walls 103, 104 may touch the floor, or the gap between the side walls 103, 104 and the floor may be small enough to prevent patient access, for example to prevent the insertion of a human hand or finger. For example, any gap between the side walls 103, 104 and the floor may be less than approximately 2cm. Forming a box bed may therefore improve the safety of the bed 100, by preventing the patient from accessing metal fixtures, cables or ligature points. Additionally, the bed 100 may provide improved versatility compared to existing box beds, by way of the raisable platform sections 131, 134, the castors 111 that allow the bed 100 to be moved across the floor and / or the platform 130 as a whole being raisable and lowerable relative to the floor. One or both side walls 103, 104 of the bed 100 may be formed of a plurality of side panels 105a-c, 106a-c, as shown in Figures 5 to 8. Alternatively, each side wall 103, 104 may be formed as a single component, as shown in Figure 1. In the illustrated example, the side walls 103, 104 are removable, so that the bed 100 can be changed between the configuration shown in Figure 1 and the configuration shown in Figure 5. The headboard 101 and footboard 102 are also removeable in the illustrated example, so that the height of the headboard and / or the footboard can be changed, as shown by comparison of Figures 7 A and 7B. However, it will be appreciated that the side walls, headboard and / or footboard could be fixed to the frame. Fixed side walls, headboards and footboards may be advantageous to improve the simplicity of manufacture, whereas replaceable side walls, headboards and footboards may be advantageous if versatility and customisability is preferred. This may also be beneficial from an economical / environmentally beneficial perspective too, since if a part is damaged it is simple to replace only the damaged part. As shown in Figures 8A and 8B, the frame 110 may comprise attachment members 160, to which the side panels 105a-c may be attachable. The side panels 105a-c may be removably attachable to the attachment members 160 of the frame 110, by sliding the side panels 105a-c relative to the attachment members 160. As shown in Figures 8A and 8B, the bed 100 may further comprise one or more pivotable latches 165. The illustrated example includes a latch 165 located towards each end of each side panel 105a-c, 106a-c. The latch 165 may be pivotable between a first position and a second position. Figure 8A shows the latch 165 in its first position. The latch 165 may be biased towards the first position by gravity. In the first position, the latch 165 may be relatively free to pivot, in other words, neither linear portion is abutting the surface, and the side panel 105a-c, 106a-c may move relative to the corresponding attachment member(s) 160, for example the side panel 105a-c, 106a-c may be raised / lowered and / or removed from the bed 100. For example, the latch 165 may be shaped such that the portion of the latch 165 on one side of the pivot point is heavier than the portion of the latch 165 on the other side of the pivot point. In this way, the latch 165 may be biased so that the heavier side of the latch 165 pivots to be closer to the floor 200 in use. In the illustrated example, the latch 165 is formed of two linear portions intersecting to form an obtuse angle. The linear portion that is closer to the side panel 105a is heaver than the other linear portion, so as to bias the latch 165 by gravity. However, it will be appreciate that any suitable shape of latch could be included. The side panels 105a-c may be slidable relative to the attachment members 160, such that the side panels 105a-c can slide into an “ultra-low” position. As shown in Figure 8B, in the ultra-low position, the side panels 105a-c are adjacent the floor 200. The side panels 105a-c in the ultra-low position and the floor 200 may be separated by a gap that is smaller than human fingers. In this way, when the side panels 105a-c are lowered to the ultra-low position, a patient may be prevented from reaching under the side panels 105a-c in order to access the frame. This can improve the safety of the bed 100, by preventing patients from accessing the components of the frame 110. The latch 165 may be configured or shaped such that contact with a surface moves the latch 165 to the second position. For example, as shown in Figure 8B, when the side panels 105a-c are lowered to the ultra-low position, the floor 200 causes the latch 165 to pivot to the second position. That is, the lowering of the side panels 105a-c, 106a-c (for example by lowering the platform 130 towards the floor) can cause the latch 165 to contact the floor 200 and pivot to a second position. In the second position, the or each latch 165 may abut a part of a corresponding attachment member 160, for example a base of the attachment member 160, thereby locking the side panel 105a in position. Therefore, in the second position, each linear portion of the latch 165 abuts a surface, thus preventing movement of a side panel 105a-c, 106a-c relative to the attachment member 160. This may prevent the patient from raising the side panel 105a, when the bed is in the ultra-low position, as shown in Figure 8B. In this way, the patient may be prevented from raising the side panels 105a to access the frame 110 of the bed 100 when the bed is being used as a box bed. In the illustrated example, the latch 165 includes a substantially flat surface 166, which is configured to abut the attachment member 160. This substantially flat surface 166 may be preferable to provide a secure locking mechanism; however, it will be appreciated that any other suitable latch shape could be used. The latch 165 may be positioned at least partially inside the side wall panels 105a-c. In this way, when the bed is in the ultra-low position, the latch 165 may be positioned such that the latch 165 is inaccessible to the patient. This may be particularly advantageous when the bed 100 is controllable by an external handset, since the handset would be required to raise, lower or remove the side panels 105a-c when the bed is in the ultra-low position. The bed 100 may be an adult bed. In this way, the distance between the headboard and the footboard may be approximately 200cm to 230cm, and preferably approximately 210cm to 220cm. The distance between the sidewalls may be approximately 80cm to 120cm, and preferably approximately 90cm to 110cm. Any gaps between the platform sections, anti-intrusion panels, side walls, headboard and footboard may be configured so as not to permit a human finger to enter. For example, any gaps may be less than approximately 2cm, preferably less than approximately 1cm, and further preferably less than approximately 0.5cm. The bed could alternatively be a junior bed. In this case, the distance between the headboard and the footboard may be approximately 120cm to 160cm, and preferably approximately 130cm to 150cm. The distance between the sidewalls may be approximately 50cm to 90cm, and preferably approximately 60cm to 80cm. Any gaps between the platform sections, anti-intrusion panels, side walls, headboard and footboard may be configured so as not to permit a child’s finger to enter. For example, any gaps may be less than approximately 1cm, and further preferably less than approximately 0.5cm. The bed 100 described herein is advantageous, since it provides an adjustable and manoeuvrable box bed, providing the versatility of an adjustable, mobile bed, in combination with the safety features of a box bed. The components of the bed 100, such as the headboard, footboard, side walls, platform sections and anti-intrusion panels, may be formed from rounded shapes. This may reduce ligature points and sharp edges in the bed, thereby improving the safety of the bed. Additionally, as shown in Figure 5, the headboard 101 and footboard 102 may each comprise one or more windows 170. Any windows 170 may be filled with any suitable material. This may be advantageous, since the filling of windows further reduces ligature points.
