Spine table positioner pad with pressure sensing and cooling features
Embodiments include a modular support pad having a support cushion, a fluid-filled bladder coupled to an electronic pressure sensor for sensing a fluid pressure within the fluid-filled bladder, and a ticking surrounding the support cushion and the fluid-filled bladder and providing a person support surface between the fluid-filled bladder and a person. Other embodiments include a modular support pad having a support cushion, a bladder coupled to an electronic pump for circulating a cooling fluid within the bladder, and a ticking surrounding the support cushion and the bladder and providing a person support surface between the bladder and a person. Methods of sensing pressure applied by a support pad are also described.
1. A method of sensing a pressure applied by a support pad, the method comprising:
positioning a support pad beneath a person, the support pad comprising a fluid-filled bladder containing a fluid comprising an oil, water, or other stable aqueous composition comprising one or more chambers, a support cushion, the fluid-filled bladder positioned between the person and the support cushion;
sensing a fluid pressure via tubing within each of the one or more chambers of the fluid-filled bladder based on an amount of the oil, water, or other stable aqueous composition entering the tubing with an electronic pressure sensor positioned external to the support pad; and
adjusting a position of the support pad horizontally along a frame relative to the person responsive to the fluid pressure.
2. The method according to claim 1 , wherein adjusting the position of the support pad reduces the fluid pressure.
3. The method according to claim 1 , further comprising:
circulating a cooling fluid through the fluid-filled bladder.
4. The method according to claim 1 , further comprising:
providing an output related to the fluid pressure.
5. The method according to claim 1 , further comprising adjusting a pressure of the fluid within at least one of the one or more chambers of the fluid-filled bladder while maintaining the pressure of the fluid within another of the one or more chambers of the fluid-filled bladder.
