Assemblies for identifying a power injectable access port
A method of power injecting a contrast medium into a patient, including obtaining a power-injectable access port suitable for power injection. The power injectable access port includes a housing defining a reservoir, and a septum. The septum may include a self-sealing material, and a radiopaque material. The radiopaque material may form a selected pattern when an x-ray is taken through the septum for identifying the power-injectable access port as being suitable for power injection. The power-injectable access port may be structured for accommodating a pressure developed within the reservoir of at least 35 psi, and may be designed to accommodate a fluid flow rate of at least 1 milliliter per second. After implanting the power-injectable access port in the patient, the method may include imaging the power-injectable access port and confirming via the selected pattern in the septum that the power-injectable access port is suitable for injecting the contrast medium.
1. A method of power injecting a contrast medium into a patient, comprising:
obtaining a power-injectable access port suitable for power injection, the power injectable access port comprising:
a housing defining a reservoir; and
a septum, comprising:
a self-sealing material; and
a radiopaque material forming a selected pattern when an x-ray is taken through the septum for identifying the power-injectable access port as being suitable for power injection, wherein:
the power-injectable access port is structured for accommodating a pressure developed within the reservoir of at least 35 psi, and
the power-injectable access port is designed to accommodate a fluid flow rate of at least 1 milliliter per second;
implanting the power-injectable access port in the patient;
imaging the power-injectable access port following the implanting;
confirming via the selected pattern in the septum that the power-injectable access port is suitable for injecting the contrast medium; and
injecting the contrast medium through the power-injectable access port into the patient.
2. The method of power injecting according to claim 1 , wherein the selected pattern in the septum includes one or more letters, and wherein the confirming step comprises recognizing the one or more letters as indicating that the power-injectable access port is suitable for injecting the contrast medium.
3. The method of power injecting according to claim 1 , wherein the injecting step comprises using an infusion set including a non-coring needle in fluid communication with a tubing, and a connector affixed to an outer surface of the tubing.
4. The method of power injecting according to claim 3 , wherein each of the non-coring needle, the tubing, and the connector have a burst pressure of at least 100 psi.
5. The method of power injecting according to claim 3 , wherein each of the non-coring needle, the tubing, and the connector have a burst pressure of at least 400 psi.
6. The method of power injecting according to claim 3 , wherein each of the non-coring needle, the tubing, and the connector have a burst pressure of at least 600 psi.
7. The method of power injecting according to claim 3 , wherein the injecting step comprises injecting the contrast medium through the infusion set at a rate of at least 5 milliliters per second.
8. The method of power injecting according to claim 1 , wherein the imaging step comprises taking an x-ray of the power-injectable access port following the implanting step.
9. The method of power injecting according to claim 1 , further comprising, prior to the injecting step, verifying that the power-injectable access port is suitable for injecting the contrast medium by visually perceiving information outside of the patient on an element packaged with the power-injectable access port.
10. The method of power injecting according to claim 9 , wherein the element is selected from the group consisting of a key chain, a bracelet, a wrist band, a sticker, a patient ID card, a label, and combinations thereof.
11. The method of power injecting according to claim 1 , wherein the injecting step comprises injecting the contrast medium through the power-injectable access port at a rate of between 1 milliliter per second and 5 milliliters per second.
12. The method of power injecting according to claim 1 , further comprising attaching a proximal end of a venous catheter to the power-injectable access port and guiding a distal end of the venous catheter through a vasculature of the patient to a target destination for the contrast medium.
