Microdrop

Abstract

The invention is a system ( 1 ), which dispenses a microliter dose of a liquid ( 6 ) or medicament. A flow channel ( 33 ) holds a dose of the liquid. A bubble ( 7 ) is located within the dose. A typical dose can be 3 microliters, or 5 microliters, including others. The invention is intended to be utilized in conjunction with gasdrop technology. a method of dispensing the dosage includes: injecting air into the inlet ( 4 ). this causes the dose to be ejected through the outlet ( 5 ). The accuracy of the dose is plus or minus 0.5 microliters.

I claim:  
     
         1 . A microliter dosage system comprising: 
 a chamber having an inlet and an outlet;    a dosage of liquid disposed within said flow channel;    at least one bubble disposed within said dosage.    
     
     
         2 . The system according to  claim 1  wherein, said dosage is between approximately 3 microliters and approximately 9 microliters.  
     
     
         3 . A microdrop comprising: 
 a ball of liquid enclosing a ball of air.    
     
     
         4 . The microdrop according to  claim 3  wherein, the quantity of said liquid is between approximately 3 microliters to approximately 9 microliters.  
     
     
         5 . A microdrop comprising: 
 one thin liquid wall comprising; 
 an exterior portion composing a bubble continuous with  
 an interior portion composing a plurality of closed compartments;  
   each said compartment encloses therein, a gas wherein, the quantity of said liquid is between approximately 3 microliters to approximately 9 microliters of a liquid.    
     
     
         6 . A microdrop comprising: 
 a ball of liquid enclosing at least 2 compartments wherein, each said compartment encloses a gas.    
     
     
         7 . The microdrop according to  claim 6  wherein, the quantity of said liquid is between approximately 3 microliters and approximately 9 microliters.
