Contrast container holder and method to fill syringes
View Patent ↗The filling of a syringe can be performed at a faster rate using a filling sequence which expels air from the fill tube before filling the syringe. A similar method is used when changing contrast containers during a filling sequence to ensure that all the air is expelled from the fill tube before filling resumes with the new contrast container. Additionally, by including a contrast container holder that is affixed to an injector head and holds the container near the syringe tip, the filling sequence can be accomplished without requiring the operator to hold the contrast container during the sequence.
1. A contrast media injector system comprising:
an injector head having a syringe mounted thereto;
a support to which said injector head is connected and relative to which said injector head may be tilted upward for a syringe filling procedure and downward for an injection procedure, wherein a discharge tip of said syringe is above a remainder of said syringe when said injector head is tilted upward;
a contrast container holder connected with the injector head and comprising an open end;
a contrast container positioned within said contrast container holder, extending through said open end of said contrast container holder, and comprising a discharge end;
a fill tube coupling said syringe to said contrast container, said contrast container holder being configured to hold said contrast container in a substantially fixed position relative to said injector head and with said open end of said contrast container holder and said discharge end of said contrast container each protecting upwardly, all while said injector head is tilted upward and as said injector system operates to fill said syringe with contrast media from said contrast container.
2. The contrast media injector system according to claim 1 wherein the contrast container holder further comprises:
a support arm having a first end and a second end, said first end adapted to couple with the injector head;
a securing portion connected to the second end, said securing portion configured to prevent movement of the contrast container substantially in a horizontal plane and a vertical plane.
3. The contrast media injector system according to claim 2 , wherein the support arm is integrally formed with the injector head.
4. The contrast media injector system according to claim 2 , wherein the first end is removably coupled with the injector head.
5. The contrast media injector system according to claim 4 , wherein said support arm further comprises:
a control portion mechanically coupled with the first end, said control portion having a first position that prevents the first end from being uncoupled from the injector head and a second position that permits the first end to be uncoupled from the injector head.
6. The contrast media injector system according to claim 1 , wherein the substantially fixed position orients the contrast container so as to be tilted toward the injector head.
7. The contrast media injector system according to claim 1 , wherein inserting or removing the contrast container relative to the contrast container holder can be accomplished by an operator of the injector system using only one hand.
8. The contrast media injector system according to claim 1 , further comprising a console designed to enable an operator to remotely control operation of the injector head.
9. The contrast media injector system according to claim 8 , wherein the console may be used to specify and store programs for automatic injection, which can later be automatically executed by the system upon initiation by an operator.
10. The contrast media injector system according to claim 8 , wherein the console comprises a touch screen display.
11. The contrast media injector system according to claim 1 , wherein the injector head comprises a pressure jacket that provides support to outer walls of the syringe.
12. The contrast media injector system according to claim 1 , further comprising a heater blanket for regulating the temperature of fluid within the syringe.
13. A contrast media injector system comprising:
a support;
an injector head interconnected with said support and comprising a syringe end, wherein said injector head is tiltable relative to said support to orient said injector head such that said syringe end projects downwardly for an injection procedure, and wherein said injector head is tiltable relative to said support to orient said injector head such that said syringe end projects upwardly for a filling procedure;
a syringe mounted to said syringe end of said injector head and comprising a syringe tip;
a contrast container holder connected with said injector head;
a contrast container disposed in said contrast container holder;
patient tubing connected with said syringe tip for execution of said injection procedure; and
a fill tube connected with each of said syringe tip and said contrast container for execution of said filling procedure, wherein only one of said patient tubing and said fill tube is connected to said syringe tip at a time, said contrast container holder being configured to hold said contrast container in a substantially fixed position when said injector head is oriented such that said syringe end projects upwardly for execution of said filling procedure.
14. The contrast media injector system according to claim 13 , wherein said injector head comprises a pressure jacket that provides support to outer walls of said syringe.
15. The contrast media injector system according to claim 13 , further comprising a heater blanket for regulating the temperature of fluid within said syringe.
16. The contrast media injector system according to claim 13 , further comprising a console designed to enable an operator to remotely control operation of said injector head.
17. The contrast media injector system according to claim 16 , wherein said console may be used to specify and store programs for automatic injection, which can later be automatically executed by said contrast media injector system upon initiation by an operator.
18. The contrast media injector system according to claim 16 , wherein said console comprises a touch screen display.
