Embodiment Construction

[0017] Injection system with motor

[0018] Referring to FIG. 1 , a syringe 20 according to the present invention includes various functional components such as a powerhead 22 , a console 24 and a power pack 26 (mounted within the cap). Injector 36 (FIG. 2) is mounted to injector 20. In panel 28 of powerhead 22, various injector controls are used to fill the injector with contrast media, such as for CT, angiography, or other procedures, and then in operation The contrast agent is injected into the subject under study under the control of personnel or predetermined programming.

[0019] The injector powerhead 22 includes a manually operable movement control lever 29 for controlling the movement of the internal drive motor, and a display 30 for displaying the current status of the injector parameters and operating parameters to the operator. The console 24 includes a touch screen display 32 which can be used by the operator to remotely control the operation of the injector 20 a...

Abstract

An intravenous contrast injector which stores different syringe definitions in firmware includes a software routine that permits a service technician to update the syringe definitions without requiring the installation of new firmware. These syringe definitions can then be used when the injector performs operational routines such as filling a syringe.

Description

technical field [0001] The present invention relates to a syringe for injecting a fluid into a patient. Background technique [0002] In many medical situations, medical fluids need to be injected into a patient during diagnosis or treatment. An example is the injection of contrast media into a patient to improve optical imaging, nuclear medicine, CT, angiography, magnetic resonance or ultrasound resonance, or any diagnostic imaging or therapeutic application using a powered autoinjector. [0003] Syringes suitable for these and similar applications typically must use larger volume syringes and be able to generate larger flow rates and injection pressures. For this reason, syringes for this application are typically motorized, including large, heavy syringe motors and transmission systems. For ease of use, the motor and transmission system are usually housed in the injection head, which is supported by a floor, wall or ceiling mounted arm. [0004] The injection head is u...
