Abstract
The present invention provides an air supply mattress control system for the release of air at a controlled pressure and temperature to a user. A mattress or support member is supplied with pressurized air and has a plurality of force activated nozzle valve assemblies positioned across the upper surface of the mattress. When the upper surface of the valves are forced downward, the valves can release air from a manifold within the mattress. The air can be conditioned and pressurized by a pump and an air conditioning unit. Operation controls can be conveniently positioned adjacent a bed frame for setting the operation conditions of the air mattress.
Claims6
A mattress used for preventing bedsores, comprising:
- a mattress body with a plurality of nozzle members that can be connected to an air supply device are mounted adjacent an upper surface of the mattress body for releasing air,
- each of the nozzle members includes a substantially cylindrical hollow main body with a valve seat member positioned within the interior of the cylindrical main body and a tube connected to a lower end of the main body to enable connection with the air supply device, and
- a movable valve assembly mounted within the cylindrical hollow main body having a valve body extending below the valve seat, an upper peak nozzle head with a plurality of pores for passing air, a hollow cylindrical tubular body connected to the nozzle head along a periphery thereof and guided along an inner side of the cylindrical hollow main body and a suspending body interconnecting the upper peak nozzle head and the valve body, wherein a force exerted against the upper peak nozzle head causes the valve body to move downward away from the valve seat to permit air to be discharged upward to be released through the pores.
A support member for supporting a user, comprising:
- a seat member with a plurality of nozzle members that can be connected to an air supply device are mounted adjacent an upper surface of the seat member for releasing air,
- each of the nozzle members includes a substantially cylindrical hollow main body with a valve seat member positioned within the interior of the cylindrical main body and a tube connected to a lower end of the main body to enable connection with the air supply device, and
- a movable valve assembly mounted within the cylindrical hollow main body having a valve body extending below the valve seat, an upper peak nozzle head with a plurality of pores for passing air, a hollow cylindrical tubular body connected to the nozzle head along a periphery thereof and guided along an inner side of the cylindrical hollow main body and a periphery thereof and guided along an inner side of the cylindrical hollow main body and a suspending body interconnecting the upper peak nozzle head and the valve body, wherein a force exerted against the upper peak nozzle head causes the valve body to move downward away from the valve seat to permit air to be discharged upward to be released through the pores.
