Device for performing regional anesthesia
An anesthetic administration device comprising an infusion device, which is in fluid connection with a regional anesthetic needle by means of a feed tube. The infusion device comprises one or more anesthetic flow devices capable of triggering forward flow, and optionally backward flow, of the local anesthetic through the regional anesthetic needle. Forward, and optionally backward flow, of the local anesthetic through the regional anesthetic needle is controlled by a controller that comprises one or more actuator switches. The one or more actuator switches are positioned on the device 1 such that they may be operated by hand.
1. An anesthetic administration device comprising:
(a) a regional anesthetic needle;
(b) an infusion device in fluid communication with the regional anesthetic needle via a feed tube, wherein the infusion device comprises one or more anesthetic flow devices capable of generating forward flow of local anesthetic through the regional anesthetic needle, wherein the anesthetic flow device generates forward flow through a volume displacement device or a pump; and
(c) a controller that comprises one or more actuator switches, wherein the one or more actuator switches activate forward, flow of the local anesthetic through the regional anesthetic needle, and wherein the one or more actuator switches are positioned on the regional anesthetic needle and/or the feed tube such that they may be operated by hand, wherein the one or more actuator switches are selected from the group consisting of: (i) one or more pushbutton switches, wherein an amount of depression of the pushbutton switch correlates with at least one of flow rate and pressure of the local anesthetic through the regional anesthetic needle; and (ii) one or more slide switches, wherein a distance that the slide switch is moved correlates with at least one of flow rate and pressure of the local anesthetic through the regional anesthetic needle.

5. The anesthetic administration device of claim 1 , wherein the one or more actuator switches operate in a first position that activates forward flow of the local anesthetic through the regional anesthetic needle, and a second position that activates backward flow of the local anesthetic through the regional anesthetic needle.
6. The anesthetic administration device of claim 1 , wherein the one or more actuator switches operate in a first position that activates forward flow of the local anesthetic through the regional anesthetic needle, a second position that activates backward flow of the local anesthetic through the regional anesthetic needle, and a third position that halts flow of the local anesthetic through the regional anesthetic needle.
7. The anesthetic administration device of claim 1 , wherein the controller comprises two actuator switches, wherein the first actuator switch is capable of activating forward flow of the local anesthetic through the regional anesthetic needle, and the second actuator switch is capable of activating backward flow of the local anesthetic through the regional anesthetic needle.
8. The anesthetic administration device of claim 1 , wherein the anesthetic administration device comprises at least one of a pressure sensor monitor and/or a flow rate monitor.
9. The anesthetic administration device of claim 8 , wherein the pressure sensor, flow rate monitor, or both comprise a visual indicator, audio indicator, or both of the pressure, flow rate, or both pressure and flow rate.
10. The anesthetic administration device of claim 9 , wherein the pressure sensor (i) actuates at least one of a visual and audio alarm when a pressure threshold is exceeded; and (ii) causes infusion to slow or stop when a pressure threshold is exceeded.
11. An anesthetic administration device comprising:
(a) a regional anesthetic needle;
(b) an infusion device in fluid communication with the regional anesthetic needle via a feed tube, wherein the infusion device comprises one or more anesthetic flow devices capable of generating forward flow of local anesthetic through the regional anesthetic needle, wherein the anesthetic flow device generates forward flow through a volume displacement device or a pump;
(c) an ultrasound probe; and
(d) a controller that comprises one or more actuator switches, wherein the one or more actuator switches activate forward flow of the local anesthetic through the regional anesthetic needle, and wherein the one or more actuator switches are positioned on the ultrasound probe, the regional anesthetic needle and/or the feed tube such that they may be operated by hand, wherein the one or more actuator switches are selected from the group consisting of: (i) one or more pushbutton switches, wherein an amount of depression of the pushbutton switch correlates with at least one of flow rate and pressure of the local anesthetic through the regional anesthetic needle; and (ii) one or more slide switches, wherein a distance that the slide switch is moved correlates with at least one of flow rate and pressure of the local anesthetic through the regional anesthetic needle.
