Abstract
An injection shut-off valve for insertion into an infusion line comprises a housing with connections for inlet and outlet lines. The housing includes an orifice for introducing an injection syringe. A valve is installed in the housing and includes a deformable diaphragm. In a non-injection state, the valve device seals off fluid flow between the inlet and outlet lines on the one hand and the orifice on the other. During injection, the diaphragm is deformed to create an opening such that fluid flow from the inlet to the housing is shut off. During deformation of the diaphragm the orifice is brought into fluid carrying communication with the outlet line from the housing, thus making it possible for the injection fluid to pass through the housing into the outlet line, and to a patient.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
