ABSTRACT:
A new intravenous fluid delivery system is disclosed. It consists of an inner product containment envelope that is covered on both sides by outer pressure envelopes. The seams of both the inner and outer envelopes are sealed together along their perimeters resulting in the outer envelopes forming a double wall around the inner product envelope. An outlet port is provided for the product containment envelope for removal of the fluids. This outlet port is similar to those found on common IV bags. A second pressure entry port is provided opposite to the outlet port. The second entry port is in communication with both outer pressure envelopes. Thus, as pressure is induced into the pressure entry port, product will be forced out of the outlet port once it is opened. As pressure in added to the outer envelopes, the inner envelope will be compressed, continuously draining the product within the product envelope until it is evacuated. Because pressure is being supplied to the outer envelopes uniformly, product will be forced out of the inner envelope regardless of the position of the invention. Thus, the invention can be placed horizontally and fluid will still flow as long as pressure is maintained in the outer envelopes. Because title inner product envelope is connected to the outer envelopes continuously along the seams, it cannot separate and collapse while leaving product in the inner envelope.
