Abstract
A patient support for supporting a patient includes an inflatable mattress defining a support surface and a pneumatic system for inflating the inflatable mattress. The pneumatic system includes a pressurized reservoir for holding pressurized air and selectively releases pressurized air from the reservoir to the mattress.
Claims20
A patient mattress comprising:
- a plurality of inflatable bladders, each bladder of the inflatable bladders having an upwardly facing bladder wall providing a patient facing side for supporting the patient on the patient mattress and a cavity;
- the inflatable bladders being formed from a first sheet of elastomeric material joined with a second sheet to form a matrix with the inflatable bladders, wherein the inflatable bladders are arranged in rows and columns, the rows extending across a width of the mattress, and the columns extending along a length of the mattress, with at least a first group of the inflatable bladders in fluid communication with each of the other bladders in the first group of the inflatable bladders wherein when a patient lies on a set of the first group of the inflatable bladders, pressure in the set of the first group of the inflatable bladders is redistributed to bladders surrounding in the set of the first group of the inflatable bladders;
- a pressure sensitive sensor disposed and overmolded on a top side of said upwardly facing bladder wall of each of the inflatable bladders of the first group of the inflatable bladders;
- a pneumatic control system;
- a controller in communication with the pneumatic control system and the sensors to monitor pressure in communication and to control the pneumatic control system to control inflation of the first group of the inflatable bladders, and the controller configured to adjust or control the pressure distribution in the first group of the inflatable bladders based on input from the sensors.

- a display, wherein the controller is in communication with the display and configured to display information relative to the mattress at the display, wherein the display displays an immersion map of a patient supported on the mattress.
3 more elements
A patient mattress comprising:
- a first sheet;
- a second sheet joined with the first sheet to form a plurality of chambers there between to form a plurality of inflatable bladders, wherein the first sheet and the second sheet form there between a plurality of passageways in fluid communication with the inflatable bladders, with each inflatable bladder being independently inflatable and controllable, and each passageway having an inlet;
- and a valve in fluid communication with each bladder of the plurality of the inflatable bladders via a respective inlet of the inlets for controlling flow of air into the plurality of the inflatable bladders.
A method of forming a patient mattress comprising the steps of:
- forming a first sheet with a plurality of sacs;
- providing a second sheet;
- joining the first sheet to the second sheet, each sac forming an upper wall of a bladder, and the upper walls having a top side for facing a patient supported thereon;
- and providing and overmolding a sensor on the top side of the upper walls of the bladders.
