An integrated motor pump for use in medical devices and the like.

Claims

exact text as granted — not AI-modified
1 . An integrated motor pump comprising:
 a) a unitary frame having a aperture for mounting a pump head and having a integrated stator winding;   b) a rotor mounted within said pump frame concentric with said stator; said rotor having an axel;   c) said rotor axel coupled to a connecting rod; said connecting rod holding a gasket;   d) said gasket forming a piston in a cylinder plate.   
   
   
       2 . The device of  claim 1  wherein said motor frame is injection molded from a high temperature plastic. 
   
   
       3 . The device of  claim 1  wherein said stator and rotor together form a brushless DC motor. 
   
   
       4 . The device of  claim 1  further comprising a pump head located proximate said aperture for regulating gas flow through an inlet and an outlet coupled to said pump head. 
   
   
       5 . The device of  claim 1  further comprising a reciprocating piston pump of the type having a rubber diaphragm forming a pump head seal and forming a first and a second leaf-a-valve for admitting an exhausting air from said pump chamber.
