Air bed having independent air chambers

Abstract

An air bed having independent air chambers is disclosed for the patients suffering with bedsores. The air bed has multiple air chambers and a pneumatic device, and the multiple air chambers are arranged in matrix on the bed. The pneumatic device includes at least one air pipe. The air chambers of odd numbers and even numbers rows are connected to different air pipes. The rows of odd number and even number chambers can be filled with air in turn, which is favorable to turn the patient, and promote blood circulation. The air chambers corresponding to the bedsore can be bound into an hour glass configuration, so that the bedsore part will not contact the air chambers, while healthy other parts supported by the air chambers will not endure much pressure, which is favorable to the patient.

1 . An air bed having independent air chambers comprising 
 a bed frame ( 11 ) with two longitudinal edges;    multiple air chambers ( 10 ) arranged in matrix mounted on the bed frame ( 11 ), wherein the chambers ( 10 ) are configured in rows, each chamber ( 10 ) is configured as a vertical cylinder, and the chambers of each row communicate with each other;    a pneumatic device including at least one air pipe, wherein each one of the at least one air pipe has a first end connected to an air pump ( 30 ), and a second end connected to the air chambers ( 10 ) located in the longitudinal edges of the bed frame ( 11 ).    
     
     
         2 . The air bed having independent air chambers as referred in  claim 1 , wherein the pneumatic device includes two air pipes ( 20 , 21 ), and each of the air pipes ( 20 , 21 ) has a first end connected to the air pump ( 30 ), and a second end connected to the air chambers ( 10 ) located in the longitudinal edges of the bed frame ( 11 ).  
     
     
         3 . The air bed having independent air chambers as referred in  claim 2 , wherein the two air pipes ( 20 , 21 ) are located in one longitudinal edge of the bed frame ( 11 ).  
     
     
         4 . The air bed having independent air chambers as referred in  claim 1 , wherein the at least one air pipe ( 20 , 21 ) is connected to the air chambers ( 10 ) through multiple branch pipes ( 50 ).  
     
     
         5 . The air bed having independent air chambers as referred in  claim 1 , wherein two pads ( 70 ) are paved in the two longitudinal edges of the bed frame ( 11 ).  
     
     
         6 . The air bed having independent air chambers as referred in  claim 1 , wherein a supporter ( 41 ) is provided below the air chambers ( 10 ).
