Monitoring injector operation

Номер: US20120204997A1
Принадлежит: ACIST Medical Systems Inc

Embodiments of the present invention monitor resistance to the movement of the ram and detect one or more injector operation conditions based on that resistance. Some embodiments automatically detect whether a syringe is present in each syringe chamber of an injector based on ram movement resistance so that subsequent steps in the inject process can be automatically initiated or delayed based on the presence or absence of the syringe(s). Other injector operation conditions that can be detected include the injector's syringe sleeve being misaligned for operation, the syringe's wiper being misaligned within the syringe barrel, an occlusion within the syringe, overpressure during injection, and so on. A common way to measure resistance of the ram's movement is how much current is required by the motor driving the ram.

A digital syringe is used with conventional polymer disposable syringe construction to be practical in the medical environment. Errors associated with the larger volumes of the syringes (which exacerbate minor errors in plunger position) and the flexibility and dimensional variations of the polymer plungers are accommodated by direct measurement of the syringe plunger position rather than indirect measurement of motor position and inference of syringe plunger position. This direct measurement eliminates mechanical tolerances (“stack up”) in the motor, gear train, and lead screw on plunger movement, an effect exacerbated by flexibility of the plunger and changes in syringe resistance and medicament viscosity, for example, with different medicaments or when the syringe is refrigerated.

A tracking unit ( 3, 4 ) tracks the location of the introduction element within a living being ( 2 ), an imaging unit ( 6 ) like an ultrasound imaging unit generates an image showing an inner part of the living being, which includes the tracked location of the introduction element, based on the tracked location, and a display ( 7 ) displays the image. During the brachytherapy or biopsy the display can always show the introduction element, without requiring a manual control. For instance, it is not necessary that a physician manually controls the position and image plane of the imaging unit. This allows for an accurate and fast insertion of the introduction element into the living being such that a target region is reliably reached.

A device for infusing a medicament into a patient includes a disposable component having a collapsible reservoir for holding the medicament, a cannula, and an elastomeric tube connected in fluid communication between the reservoir and the cannula. A manipulator is mounted on a chassis for engagement with the elastomeric tube. The manipulator includes a piston and respective pinchers upstream and downstream from the piston for a close/open open/close changeover operation. In concert therewith, the piston cyclically advances and withdraws relative to a platen to thereby alternatingly dilate/constrict the tube section. When the upstream pincher is open, the piston withdraws to create a low fluid pressure, pLo, in the tube section to draw medicament into the tube. Alternately, when the downstream pincher is open, the piston is advanced to create a high fluid pressure, pHi, on the tube to infuse medicament into the patient.
