Abstract
A patient support apparatus includes a mattress that defines a plurality of grooves. A bladder is disposed within each groove. Each bladder is operable between a deployed state and a non-deployed state. A flap is disposed adjacent to each groove. Each flap includes a broad contact surface and a narrow contact surface. A manifold is in fluid communication with each bladder. The manifold is configured to direct fluid into each bladder to adjust the bladders between the deployed state and the non-deployed state, and consequently move the flaps between a raised position and a lowered position, respectively.
Claims20
A patient support apparatus, comprising:
- a mattress defining a plurality of grooves;
- a bladder disposed within each groove, wherein each bladder is operable between a deployed state and a non-deployed state;
- a flap disposed adjacent to each groove, wherein each flap includes a broad contact surface and a narrow contact surface;
- and
- a manifold in fluid communication with each bladder, wherein the manifold is configured to direct fluid into each bladder to adjust the bladders between the deployed state and the non-deployed state, and consequently move the flaps between a raised position and a lowered position, respectively.
A mattress system for a patient support apparatus, comprising:
- a mattress defining a groove, wherein the mattress includes a base surface;
- a bladder disposed within the groove, wherein the bladder is operable between a deployed state and a non-deployed state;
- a flap disposed adjacent to the groove, wherein the flap is operable between a raised position and a lowered position;
- and
- a manifold configured to adjust the bladder between the deployed state and the non-deployed state, wherein the flap rotates away from the base surface as the bladder is adjusted from the non-deployed state to the deployed state.
A mattress system for a patient support apparatus, comprising:
- a mattress having a support surface, wherein the mattress defines a cavity therein;
- a first bladder disposed within the cavity;
- a second bladder disposed within the cavity proximate the first bladder, wherein each of the first bladder and the second bladder are operable between an expanded state, a compressed state, and a neutral state;
- a pump in fluid communication with each of the first bladder and the second bladder, wherein the pump defines a first port and a second port;
- and
- a manifold in fluid communication with the first bladder, the second bladder, and the pump, wherein the pump is configured to evacuate fluid from the first bladder when the manifold is in a first operating state and configured to evacuate fluid from the second bladder when the manifold is in a second operating state to influence a shape of the support surface of the mattress.
