Procedure and device for the movement and volume measurement of fluids and gases and device for the implementation of a respiration
First Claim
1. A device for movement and measurement of a fluid volume, with the fluid volume being defined in a measuring chamber of a rotation vessel by at least first and second pistons movable within the measuring chamber, said pistons separating the fluid volume and indicating fluid-volume movement into and out of the measuring chamber via flow-regulating valves, the device comprising:
- the rotation vessel;
the flow-regulating valves;
the at least first and second pistons, which are alternately rotated and held fixed;
holding means for alternately fixedly holding the first and second pistons within the measuring chamber;
wherein, during a first cycle phase, a volume of fluid flows into a first measuring space within the measuring chamber, said first measuring space being defined by at least the first piston, which is held fixed within the measuring chamber by the holding means, and by at least the second piston, which is movable within the measuring chamber; and
wherein, during a second cycle phase, the volume of fluid in the first measuring space flows out of the first measuring space as the second piston is held fixed within the measuring chamber by the holding means and the first piston is movable within the measuring chamber;
wherein the first measuring space is separated from a second measuring space of the measuring chamber by at least one of said first and second pistons.

Abstract
A device and method for movement and measurement of fluid volumes involves defining a fluid volume in a measuring chamber of a rotation vessel by at least first and second pistons movable within the measuring chamber, with the first and second pistons separating and indicating the volume of fluid moved into and out of the measuring chamber via flow-regulating valves. A holding means alternately holds the first and second pistons at fixed positions within the measuring chamber while the other piston rotates. A device and method of respiration involves a respirator including a plurality of flexible gas bags and a stiff gas tank with a first flexible gas bag positioned inside a second flexible gas bag and both gas bags being positioned inside the stiff tank. The respirator is connected to the device for the movement and measurement of fluid volumes via respirator valves.

17. The device of claim 16, wherein said respirator includes a container for holding a liquid vital anesthetic.
-
18. The device of claim 16, wherein the respirator includes a material in which a vital anesthetic of the respirator system is released, wherein said material is chosen from one of fats, oils, paraffin oil, saturated and unsaturated fatty acids, aliphatic substances, lipophile mixtures or emulsions.

19. A method for movement and measurement of fluid volumes with a fluid volume being defined in a measuring chamber of a rotation vessel by at least first and second pistons movable within the measuring chamber, said first and second pistons separating and indicating the fluid volume of fluid moved into and out of the measuring chamber via flow-regulating valves, the method comprising first-measuring-space cycle steps as follows:
-
opening a first of the flow-regulating valves leading into a first measuring space within the measuring chamber to flow a first volume of fluid into the first measuring space, the first measuring space being limited by at least the first piston that is held fixed within the measuring chamber while the second piston is allowed to rotate away from the first piston; and
opening a second of the flow-regulating valves leading from the first measuring space to flow the first volume of fluid out of the first measuring space, the first measuring space now being defined by at least the second piston that is held fixed while the first piston is allowed to rotate toward the second piston. - View Dependent Claims (20, 21, 22, 23)
providing a respirator comprising a plurality of flexible gas bags and an outer tank and respirator valves, wherein a first flexible gas bag is positioned inside a second flexible gas bag and both gas bags are positioned inside said outer tank, with the respirator being connected to the device for the movement and measurement of fluid volumes via said respirator valves;
providing compression within said outer tank on the second flexible gas bag, thereby causing compression of both the second and first gas bags for thereby propelling gas in the flexible gas bags to a patient via the respirator valves and the device for the movement and measurement of a fluid volume.
