Abstract:
1. A method for testing a device for a fluid leak, the method comprising: a. connecting the device to a pump connected to a reservoir of fluid, wherein the device has a fluid seal; b. connecting a control device to the pump; c. simultaneously pumping the fluid into the device and the control device; d. detecting a pressure of the fluid flowing to the control device, forming a control response; e. detecting a pressure of the fluid flowing to the device, forming a test response; f. determining a difference between the test response and the control response, forming a pressure difference; g. adjusting a volume of the fluid in the control device by a known volume; h. determining a drop in the pressure difference associated with the known volume; i. forming a leak test ratio by dividing the known volume by the drop in the pressure difference; and j. determining if the test response imitates the control response by determining if a change in the pressure difference occurs, wherein:
