The connection surface is configured to grasp a rotary dial of a medicinal pen. The handle further includes a cap rotatingly coupled to the frame. The cap is configured to rotate with respect to the frame. ## Claims ### Claim 1 A handle, comprising: a frame having an outer diameter that is between 50 millimeters and 70 millimeters; a connection surface coupled to the frame and configured to grasp a rotary dial of an insulin pen, wherein the connection surface comprises an elastomer washer, wherein the elastomer washer has an opening, configured to receive the rotary dial of the insulin pen, and wherein the opening has an inner diameter that is between 14 millimeters and 17 millimeters; a locking surface coupled to the frame, the locking surface having a first diameter and a second diameter, wherein the second diameter is lamer than the first diameter, and wherein the second diameter of the locking surface is configured to engage one or more locking hooks on the frame to lock the locking surface into the frame, wherein the connection surface is positioned in-between an inside portion of the frame and a bottom portion of the locking surface; a cap rotatingly coupled to the frame, the cap being configured to rotate with respect to the frame, wherein the cap has a protrusion extending from an inside top surface of the cap towards the frame, wherein the protrusion is configured to contact an upper surface of the rotary dial of the insulin pen when a user applies three against an outside top surface of the cap; and wherein the frame and connection surface are configured to be rotated with respect to the cap by a rotation of the rotary dial of the insulin pen. ### Claim 2 (depends on 1) The handle of claim 1, wherein the inner diameter is approximately 1 millimeter smaller than an outer diameter of the rotary dial of the insulin pen. ### Claim 3 (depends on 1) The handle of claim 1, wherein the cap has an outer diameter that is between 49 millimeters and 70 millimeters. ### Claim 4 (depends on 1) The handle of claim 1, wherein the cap has one or more rubber tips positioned on an outside top surface of the cap. ### Claim 5 A method, comprising: coupling a connection surface to a frame of a handle, the frame having an outer diameter that is between 50 millimeters and 70 millimeters, the connection surface being configured to grasp a rotary dial of a medicinal an insulin pen, wherein the connection surface comprises an elastomer washer, wherein the elastomer washer has an opening configured to receive the rotary dial of the insulin pen, and wherein the opening has an inner diameter that is between 14 millimeters and 17 millimeters; coupling a locking surface to the frame, the locking surface having a first diameter and a second diameter, wherein the second diameter is larger than the first diameter, and wherein the second diameter of the locking surface is configured to engage one or more locking hooks on the frame to lock the locking surface into the frame, wherein the connection surface is positioned in-between an inside portion of the frame and a bottom portion of the locking surface; rotatingly coupling a cap to the frame, the cap being configured to rotate with respect to the frame, wherein the cap has a protrusion extending from an inside top surface of the cap towards the frame, wherein the protrusion is configured to contact an upper surface of the rotary dial of the insulin pen when a user applies force against an outside top surface of the cap; and wherein the frame and connection surface are configured to be rotated with respect to the cap by a rotation of the rotary dial of the insulin pen. ### Claim 6 (depends on 5) The method of claim 5, wherein the inner diameter is approximately 1 millimeter smaller than an outer diameter of the rotary dial of the insulin pen. ### Claim 7 (depends on 5) The method of claim 5, further comprising: inserting the rotary dial of the insulin pen into the opening of the connection surface so that the connection surface grasps the rotary dial of the insulin pen; rotating the frame so that the rotary dial of the insulin pen also rotates; inserting an injection port of the insulin pen into a subject; and applying force against an outside top surface of the cap so that the insulin pen injects insulin into the subject through the injection port of the insulin pen.
