 wherein the controller is configured to:
 subsequently determine to stand by, output an alarm through the output module to notify standby for initiation, and 
 receive at least one of target temperature information, target cooling duration, a type of therapy, or a site of therapy before activating the valve. 
 
 
     
     
         7 . The device of  claim 6 ,
 wherein the input element comprises a wheel switch, and   wherein the controller is configured to set the target temperature in response to a rotation of the wheel switch for changing the target temperature and pushing the wheel switch for selecting the target temperature.   
     
     
         8 . The device of  claim 6 ,
 wherein the input element comprises a wheel switch, and   wherein the controller is configured to set the target cooling duration in response to a rotation of the wheel switch for changing the target cooling duration and pushing the wheel switch for selecting the target cooling duration.
