Front-loading medical injector adapted to releasably engage a syringe regardless of the orientation of the syringe with respect to the injector
A syringe for use with an injector includes a body having a rear end and a front end, a plunger movably disposed within the body, an attachment member associated with the body and adapted to releasably engage a syringe retaining mechanism of the injector regardless of the orientation of the syringe with respect to the injector, and an encoding device operable to provide syringe information to the injector.
1. A method of connecting a syringe comprising a syringe body having a proximal end, a distal end with a nozzle, and at least one attachment member protruding radially outward relative to the syringe body at the proximal end of the syringe to an injector comprising a syringe retaining mechanism, the method comprising:
moving the at least one attachment member of the syringe into the syringe retaining mechanism without regard to a rotational orientation of the syringe about a syringe longitudinal axis relative to a longitudinal axis of the syringe retaining mechanism; and
releasably engaging the at least one attachment member of the syringe with the syringe retaining mechanism of the injector.
2. The method of claim 1 wherein moving the at least one attachment member of the syringe into the syringe retaining mechanism comprises axially moving the syringe into the syringe retaining mechanism.
3. The method of claim 1 wherein moving the at least one attachment member of the syringe into the syringe retaining mechanism comprises vertically moving the syringe into the syringe retaining mechanism.
4. The method of claim 1 , further comprising:
providing an actuator member associated with the syringe retaining mechanism and adapted to be rotated by the syringe to urge the syringe retaining mechanism out of engagement with the at least one attachment member of the syringe; and
rotating the syringe to release the at least one attachment member from the syringe retaining mechanism.
5. The method of claim 1 , further comprising: manipulating the syringe retaining mechanism to release the at least one attachment member therefrom.
6. The method of claim 1 , further comprising: moving the syringe against the syringe retaining mechanism to release the at least one attachment member therefrom.
7. The method of claim 1 , further comprising:
providing an actuator member adapted to engage the at least one attachment member of the syringe;
activating the actuator member to urge the at least one attachment member out of engagement with the syringe retaining mechanism to release the syringe from the injector.
8. The method of claim 1 , further comprising:
providing an encoding device on the syringe, wherein the encoding device is adapted to provide syringe information;
providing a sensor on the injector, wherein the sensor is adapted to read the syringe information; and
reading the syringe information as the syringe is connected to the injector.
9. A method of connecting a syringe comprising a syringe body having a proximal end, a distal end with a nozzle, and at least one attachment member protruding radially outward relative to the syringe body at the proximal end of the syringe to an injector comprising a syringe retaining mechanism, the method comprising:
moving the at least one attachment member of the syringe into the syringe retaining mechanism without regard to a rotational orientation of the syringe about a syringe longitudinal axis relative to a longitudinal axis of the syringe retaining mechanism;
releasably engaging the at least one attachment member of the syringe with the syringe retaining mechanism of the injector; and
providing an encoding device on the syringe, wherein the encoding device is adapted to provide syringe information.
10. The method of claim 9 wherein moving the at least one attachment member of the syringe into the syringe retaining mechanism comprises axially moving the syringe into the syringe retaining mechanism.
11. The method of claim 9 wherein moving the at least one attachment member of the syringe into the syringe retaining mechanism comprises vertically moving the syringe into the syringe retaining mechanism.
12. The method of claim 9 , further comprising:
providing an actuator member associated with the syringe retaining mechanism and adapted to be rotated by the syringe to urge the syringe retaining mechanism out of engagement with the at least one attachment member of the syringe; and
rotating the syringe to release the at least one attachment member from the syringe retaining mechanism.
13. The method of claim 9 , further comprising: manipulating the syringe retaining mechanism to release the at least one attachment member therefrom.
14. The method of claim 9 , further comprising: moving the syringe against the syringe retaining mechanism to release the at least one attachment member therefrom.
15. The method of claim 9 , further comprising:
providing an actuator member adapted to engage the at least one attachment member of the syringe;
activating the actuator member to urge the at least one attachment member out of engagement with the syringe retaining mechanism to release the syringe from the injector.
16. The method of claim 9 , further comprising:
providing a sensor on the injector, wherein the sensor is adapted to read the syringe information; and
reading the syringe information as the syringe is connected to the injector.
