Modular stretcher for patient transport apparatus

A patient transport system comprising:

• a patient transport apparatus including:
• a base, the base supporting wheels arranged for movement along a floor surface,
• an intermediate frame disposed above the base and extending longitudinally between a head end and a foot end and extending laterally between a left side and a right side,
• a support deck operatively attached to the intermediate frame for supporting a patient,
• a lift mechanism interposed between the base and the intermediate frame for moving the intermediate frame relative to the base between a plurality of vertical configurations,
• a siderail operatively attached to the intermediate frame,
• a siderail bracket coupled to the siderail, and
• a wing segment configured for releasable engagement with the siderail bracket,
• wherein the siderail is operable between:
• a first configuration where the siderail defines a first size based on disengagement of the wing segment from the siderail bracket, and
• a second configuration where the siderail defines a second size larger than the first size based on engagement of the wing segment to the siderail bracket;
• and
• a patient support apparatus including:
• a hinge member;
• and
• a support board coupled to the hinge member, the support board including a distal segment and a proximal segment removably coupled to the distal segment,
• wherein the wing segment of the siderail is configured for coupling to the distal segment of the support board during operation of the siderail in the first configuration.
