Abstract
Method and systems for determining acceptance criteria for identification of occluding particles in a lumen of a device are provided. The methods and systems can be used in methods of identifying an occluded device in an inspection method. The method can include obtaining or having obtained a flow measurement for the device to be inspected and comparing the flow measurement in the device to acceptance criteria for a representative device.
Claims8
A method of detecting a change in a lumen property of a lumen device, the method comprising:
- a. obtaining or having obtained a flow measurement for the device to be inspected;
- and
- b. comparing the flow measurement in the device to an upper test limit of flow obtained for an occluded representative device with a defined level of occlusion;
- wherein the lumen property of the device to be inspected is determined to be changed if the flow measurement for the device to be inspected is equal to or lower than the upper test limit of flow, and the lumen property of the device to be inspected is determined to be unchanged if the flow measurement for the device to be inspected is greater than the upper test limit of flow.
