BLOOD VESSEL ACCESS SYSTEM AND DEVICE |
摘要 |
An access system and 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 having an expected path trajectory is overlapped on at least one of a transverse short axis, a longitudinal long axis, or a three-dimensionally imaged blood vessel that illustrates the predicted path of the needle or needle with overlapping cannula when it undergoes movement implemented by a controller located on the needle injector. 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. |
