Abstract

A device having a needle injector pivotally attached to an ultrasound transceiver is operated to place a sterilizable needle or needle/cannula unit within a blood vessel by a single user-device operator in which the blood vessel is made visible in a monitor image by ultrasound insonification. A guidance template is overlapped on at least one of a transverse, longitudinal, or three-dimensionally imaged blood vessel that illustrates a predicted path of the needle when it undergoes movement implemented by a controller. In alternate embodiments the needle injector, ultrasound transceiver, and needle or needle/cannula unit may be contained within a flexible sheath that is capable of being sterilized.

Claims

1. An access system operated by a user directed to placing a needle in a blood vessel of a patient, the system comprising:

an ultrasound transceiver sonically coupled to convey ultrasound energy into the patient and generate signals from the ultrasound energy returning from the patient;

a monitor configured to present an image having at least one blood vessel derived from the signals;

a needle injector pivotally connected with the ultrasound transceiver, the needle injector having a needle configured for slidable connection with a cannula; and

a controller in communication with the needle injector;

wherein positioning of the needle within the blood vessel is determined by operation of the controller by the user viewing the image.

2. The access system of claim 1, wherein the image includes at least one of a cross-sectional view, a longitudinal cross-sectional view, and a three dimensional rendering of the at least one blood vessel.

3. The access system of claim 1, wherein the image includes a window to display a sonic pattern to discern whether the at least one blood vessel is an artery or a vein.

4. The access system of claim 1, wherein the image includes a window to display color Doppler graphics to discern whether the at least one blood vessel is an artery or a vein.

5. The access system of claim 1, wherein the needle injector is includes a cannula that at least partially overlaps the needle.

6. The access system of claim 1, wherein the needle injector is includes a cannula that at least partially overlaps the needle and is contained within a sterilizable housing detachably connectable with the needle injector.

7. The access system of claim 1, wherein the ultrasound transceiver, the needle injector, and the controller is configured for enveloping within a flexible sheathing capable of undergoing a sterilization process.

8. The access system of claim 1, wherein the image includes an overlay presenting a predicted path of the needle from the needle injector to the lumen of the at least one blood vessel.

9. The access system of claim 1, wherein the image includes an overlay presenting a predicted path of the needle from the needle injector to the lumen of the at least one blood vessel, the overlay presented on the monitor displaying at least one of a transverse cross-sectional view, a longitudinal cross-sectional view, and a three dimensional view of the at least one blood vessel.

10. An access device operated by a user in conjunction with an ultrasound transceiver having a monitor configured to display an image of at least one blood vessel of a patient, the device comprising:

a needle injector pivotally connected with the ultrasound transceiver, the needle injector having a needle configured for slidable connection with a cannula; and

a controller in communication with the needle injector;

wherein positioning of the needle within the blood vessel is determined by operation of the controller by the user viewing the image.

11. The access device of claim 10, wherein the image includes at least one of a transverse cross-sectional view, a longitudinal cross-sectional view, and a three dimensional rendering of the at least one blood vessel.

12. The access device of claim 10, wherein the needle injector is includes a cannula that at least partially overlaps the needle.

13. The access device of claim 10, wherein the needle injector is includes a cannula that at least partially overlaps the needle and is contained within a sterilizable housing detachably connectable with the needle injector.

14. The access device of claim 10, wherein the ultrasound transceiver, the needle injector, and the controller is configured for enveloping within a flexible sheathing capable of undergoing a sterilization process.

15. The access device of claim 10, wherein the image includes an overlay presenting a predicted path of the needle from the needle injector to the lumen of the at least one blood vessel.

16. The access device of claim 10, wherein the image includes an overlay presenting a predicted path of the needle from the needle injector to the lumen of the at least one blood vessel, the overlay presented on the monitor displaying at least one of a transverse cross-sectional view, a longitudinal cross-sectional view, and a three dimensional view of the at least one blood vessel.

17. A method to access at least one blood vessel of a patient, the method comprising:

connecting a needle injector pivotally with an ultrasound transceiver having a monitor configured to present an image of the at least one blood vessel, the needle injector having a needle configured for slidable connection with a cannula;

overlaying a predicted path of the needle for entry into the at least one blood vessel;

operating a controller in communication with the needle injector;

positioning the needle within the blood vessel via operation of the controller by the user viewing the predicted path undertaking by the needle as appearing within the image.

18. The access method of claim 17, wherein the overlay is presented on the monitor displaying at least one of a transverse cross-sectional view, a longitudinal cross-sectional view, and a three dimensional view of the at least one blood vessel.

19. A method to access at least one blood vessel of a patient, the method comprising:

connecting a needle injector pivotally with an ultrasound transceiver having a monitor configured to present an image of the at least one blood vessel, the needle injector connectable with a sterilizable housing having a needle configured for slidable connection with a cannula;

overlaying a predicted path of the needle for entry into the at least one blood vessel;

operating a controller in communication with the needle injector;

positioning the needle within the blood vessel via operation of the controller by the user viewing the predicted path undertaking by the needle as appearing within the image.

20. The access method of claim 20, wherein the overlay is presented on the monitor displaying at least one of a transverse cross-sectional view, a longitudinal cross-sectional view, and a three dimensional view of the at least one blood vessel.

22. The access method of claim 20, wherein the overlay is presented on the monitor displaying at least one of a transverse cross-sectional view, a longitudinal cross-sectional view, and a three dimensional view of the at least one blood vessel.

21. A method to access at least one blood vessel of a patient, the method comprising:

connecting a needle injector occupying pivotally with an ultrasound transceiver having a monitor configured to present an image of the at least one blood vessel, the needle injector connectable with a sterilizable housing having a needle configured for slidable connection with a cannula;

enveloping the needle injector, the ultrasound transceiver, and the sterilizable housing within a flexible, sterilizable sheath;

overlaying a predicted path of the needle for entry into the at least one blood vessel;

operating a controller in communication with the needle injector;
