         14 . The wound irrigation device according to    claim 13   , wherein said splash guard comprises a removable protective cap.  
     
     
         15 . The wound irrigation device according to    claim 1   , wherein said discharge means is an adjustable discharge means, whereby said adjustable discharge means permits adjustment of the rate of discharge of said irrigation solution.  
     
     
         16 . The wound irrigation device according to    claim 15   , wherein said adjustable discharge means comprises a valve cap and a valve head, wherein said valve cap is removably affixed to said reservoir housing and said valve head is threadably affixed to said valve cap.  
     
     
         17 . The wound irrigation device according to    claim 16   , wherein said valve cap comprises an inner air inlet and an inner water outlet, wherein said inner water outlet substantially surrounds said inner air inlet.  
     
     
         18 . The wound irrigation device according to    claim 17   , wherein said valve head comprises an outer air inlet and an outer water outlet, wherein said outer water outlet substantially surrounds said water air inlet.  
     
     
         19 . The wound irrigation device according to    claim 18   , wherein said outer air inlet comprises a circular port.  
     
     
         20 . The wound irrigation device according to    claim 18   , wherein said outer water outlet comprises a plurality of circular ports.  
     
     
         21 . The wound irrigation device according to    claim 18   , wherein said inner air inlet and said outer air inlet combine to form an air inlet, and said inner water outlet and said outer water outlet combine to form a water outlet.
