- the bed side sheets may be coupled to the patient side sheet and each bed side sheet may be separated by a gap. The gaps are extending in the transverse direction.
- the bed side sheets may be welded to the patient side sheet.
- Each bed side sheets being welded to the patient side sheet may be configured as a patient support section pivotally coupled to an adjacent patient support section,
- the patient support may be an enclosed construction.
- An enclosed construction may be easy to clean, maintain, assemble and produce.
- the gap(s) between the bed sheet, and thus a transverse part of the patient side sheet being unsupported by the patient support sheets may form a compression path and thereby function as hinges.
- Compression path is used to describe the transverse section of the patient support, which may be bendable due to the gap in the transverse direction created on the bed face between the bed side sheets.
- This section may be bendable as it only comprises the patient side sheet, which may be compressible and thus a repeatedly bending in this section will not cause fatigue in the patient support.
- Each patient support section is divided by the compression path formed by the gaps between the bed side sheets.
- a further effect of this embodiment is that the support section may help the patient to reposition.
- the physical comfort will increase which may lead to early recovery.
- a further advantage of this embodiment is that the head section may be raised to obtain Fowler position.
- the Fowler position may benefit the staff and the patient as it may be used for sitting (e.g. while feeding) and may ease the user's breathing.

- the bending actuator may be arranged and connected to the interior of the elongated housing and configured to move the operably connected patient support section(s) relatively to another patient support section.
- the support frame may be length-adjustable. Thereby it may be used for different purposes and for paediatric patients.
- the patient support may be made of thermoplastics such as acrylonitrile butadiene styrene, polypropylene, polycarbonate or other polymers. Thereby the patient support may obtain a smooth exterior which is easy to clean and maintain. A person skilled in the art may choose different materials to obtain different purposes.
- the sheets may be made of a material compatible with imaging procedures. Thereby it may not be necessary to move the user if a medical imaging such as MRI is needed.
- the patient side sheet may be made of a flexible plastics material and the bed side sheets may be made of a strong plastics material.
- An effect of this embodiment is that the sheet is made of a flexible and bendable material whereas the other sheet is made of a strong material.
- the patient support may be both flexible and may pivot in the desired angles and may be strong with a high durability.
- the patient support may comprise a smooth easy-to-clean surface.
- the sheets may be made of different materials or different thicknesses or both. Thereby it is possible to use different materials with different properties suitable for the use of the bed.
- the patient support may have a bed face which comprises at least one connection means.
- the connection means may be one or more nut(s).
- the connection means may be embedded into at least one bed side sheet for connecting and fixating the patient support to the hospital bed.
- the patient support may be attached to the hospital bed by a connection means extending from the hospital bed to the patient support. Thereby the patient support may still have a smooth exterior patient support face which is easy to clean and maintain.
- a further advantage is that there are no gaps, cavities or the like on the exterior patient support face, thereby eliminating potential entrapment areas for fingers or small objects.
- gaps used in hospital beds are either smaller than 8 mm or larger than 25 mm. This embodiment allows for the use of different types and sizes of gaps without consideration of entrapment areas.
- the patient support may easily be taken off/onto the hospital bed. Thereby cleaning of the hospital bed is possible without the patient support.
- connection means may be a nut, coupling, bolt, cable or the like, or any combination of those. Thereby a person skilled in the art may choose the most appropriate connection means.
- connection means may be located in the interior of the housing. Thereby cleaning is easier.
- the patient support comprising a compression path may be obtained by a process comprising several acts.
- the acts may be one or more of:
- a further advantage is that the two sheets may be welded together in several points. Thereby the construction may be stronger and tighter compared to conventional patient supports.
- the patient side sheet is made of a flexible plastics material and the at least two bed side sheets are made of a strong plastics material.
- the process is twinsheet thermoforming.
- An effect of this embodiment is that twinsheet thermoforming is simpler than several conventional processes. Thereby twinsheet thermoforming may create higher production rates.
- a further advantage is that when no screws, bolts, hinges or the like are needed, the exterior patient support face is easy to clean and maintain.
- a further advantage is that there is no noise from hinges and the like, thereby creating a peaceful environment for the user and caretaker.
- twinsheet thermoforming provides a simple construction with low weight. Thereby the patient support may be easy to remove e.g. for cleaning or transport.
- the patient support may comprise one or more internal reinforcements such as structural elements or rigid foam components.
- internal reinforcements such as structural elements or rigid foam components.
- the patient support is obtained by a twin sheet thermoforming process wherein a bed side sheet and a patient sheet is provided to be formed in their respective moulds. At least the mould for the bed side sheet may comprise one or more transverse protrusions. The transvers protrusions may accommodate transverse gaps in the bed side sheet and thus the forming of compression paths in the patient support.
- the division of individual patient support sections is formed by squeezing, pressing or the like in a transverse direction. Thereby it is possible to bend the patient support between the patient support sections.
- the patient support may be obtained by providing at least one sheet for the exterior patient support face and at least two sheets for the bed face.
- the sheets are placed in a female mould and heated to their respective thermoforming temperatures. Then the two mould halves are sealed together. Air pressure may be applied to the moulds through needles, and a vacuum is created so the sheets are formed against the moulds.
- a hollow part may be formed by the sheets.
