Method and apparatus for applying a medically useful multiple component material

Abstract

An applicator gun for spraying a medically useful multiple component fluid to an area of interest. The handheld applicator gun functionally receives a commercially available or standardized multi-syringe applicator, and dispenses fluid from the multi-syringe applicator in a controllable manner. The handheld applicator gun further includes a return stop and a dispensing stop to limit the force exerted on the multi-syringe applicator.

         5 . The device of  claim 1 , where said applicator housing further comprises an interface cavity capable of receiving said multi-syringe applicator.  
     
     
         6 . The device of  claim 5 , wherein said interface cavity is capable of receiving a plurality of multi-syringe applicators.  
     
     
         7 . The device of  claim 1 , wherein said engagement member further comprises a pushing interface.  
     
     
         8 . The device of  claim 7 , wherein said pushing interface further comprises a force dampener.  
     
     
         9 . The device of  claim 8 , wherein said force dampener is made of an elastomer.  
     
     
         10 . The device of  claim 8 , wherein said force dampener is made of silicon.  
     
     
         11 . The device of  claim 1 , wherein said return stop is positioned to contact said moveable trigger device, thereby limiting the stroke length of said moveable trigger device.  
     
     
         12 . The device of  claim 11 , wherein said moveable trigger device further comprises a trigger biasing member, said trigger biasing member forcing said moveable trigger device to contact said return stop absent the application of pressure to said moveable trigger device.  
     
     
         13 . The device of  claim 12 , wherein said trigger biasing member is a spring.  
     
     
         14 . The device of  claim 1 , wherein said dispensing stop is positioned to contact said moveable trigger device, thereby limiting the quantity of said first component and second component dispensed at one time.  
     
     
         15 . The device of  claim 1 , wherein said stationary handle forms a pistol-type grip.  
     
     
         16 . The device of  claim 1 , wherein said applicator housing is capable of receiving a spray producing device, thereby enabling the sprayed application of said first and second components.  
     
     
         17 . A multi-component applicator for mixing and applying at least a first and a second component, comprising: 
 a multi-syringe applicator comprising at least a first syringe container storing a first component therein, and having a first syringe piston connected to a first piston rod disposing a first pusher, and at least a second syringe container storing a second component therein, and having a second syringe piston connected to a second piston rod disposing a second pusher;    a handheld applicator gun comprising an elongated body portion, a stationary handle portion, and a moveable trigger device;    said moveable trigger device connected to said applicator housing and adjacent thereto;    said moveable trigger device comprising a movement actuator connected to an advanceable engagement member, said advanceable engagement member comprising a pushing interface having a force dampener attached thereto,    wherein actuation of said moveable trigger device advances said engagement member; and    a return stop and a dispensing stop connected to said applicator housing and engageable with said moveable trigger device; thereby limiting the advancement stroke lengths first and said second pistons disposed in said first and second containers    
     
     
         18 . A method of optimizing the force applied by a handheld applicator, comprising: 
 providing a handheld applicator capable of exerting increased force on a multi-component applicator coupled thereto, said handheld applicator providing a mechanical advantage in applying said force; and    regulating the application of said force applied by said handheld applicator to said multi-component applicator.    
     
     
         19 . The method of  claim 18 , wherein said regulation of said applied force is accomplished by a dispensing stop, thereby limiting the mechanical advantage obtained by said handheld applicator.  
     
     
         20 . The method of  claim 18 , wherein said regulation of said applied force is accomplished by a return stop, thereby limiting the mechanical advantage obtained by said handheld applicator.  
     
     
         21 . The method of  claim 18 , wherein said regulation of said applied force is accomplished by a dispensing stop and a return stop, thereby limiting the mechanical advantage obtained by said handheld applicator.
