12. The device of claim 4 wherein the adhesive bond between the needle and the polymer wrap is broken when the formulation is pushed through the space between the needle and the polymer wrap.
13. A method for injecting a formulation into skin comprising:
penetrating the skin with a device of claim 1:
pushing the formulation through the device such that the formulation passes through a space between the needle and the polymer wrap.
14. The method of claim 13 wherein the hub of the device further comprises a connector for connecting the hub to a housing for receiving formulation.
15. The method of claim 14 wherein the housing is a syringe, the syringe comprises a plunger, and the formulation is pushed through the device by applying pressure to the plunger.
16. The method of claim 15 wherein the formulation flows from the housing into the polymer wrap causing an adhesive bond between the needle and the polymer wrap to break, thus creating a flow path from the housing to the exterior of the device.
17. The method of claim 14 wherein the connector of the device is selected from the group consisting of: a threaded connector and a quick release connector.
18. The method of claim 13 wherein at least a portion of the polymer wrap is inserted into the skin when the point of the needle penetrates the skin.
19. The method of claim 17 wherein the polymer wrap expands radially when the formulation is pushed through the space between the needle and the polymer wrap.
20. (canceled)
21. The device of claim 13 wherein the diameter of the needle and at least a portion of the diameter of the hub lies in the flow path of the formulation into the skin.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A holder comprising:
a seat including an adhering member provided in its bottom;
a flexible arm having one end connected to a top of the seat;
a connection member removably connected to the other end of the arm;
a support connected to the other end of the arm, the support having its bottom to be in contact the connection member such that the support is adapted to rotate relative to the connection member, and its top adapted to support and fasten an electronic device; and
an adjustment member rotatably provided at the other end of the arm proximate the connection member, the adjustment member being adapted to move either toward the connection member for gradually tightly engaging the connection member and the support together or away from the connection member for gradually loosening the connection member and the support.
2. The holder of claim 1, further comprising a projection formed on an underside of the support, a protrusion formed on the other end of the arm, and an indentation formed on a top of the connection member facing the support wherein the projection is pivotably provided in the indentation for permitting the support to swing in the indentation, and the connection member further comprises a central opening, the central opening being adapted to matingly put on the protrusion for sleeving the connection member on the protrusion and sliding the connection member along the protrusion.
3. The holder of claim 2, wherein the support further comprises:
a cavity provided in the projection;
a tunnel passed through the projection and the cavity;
a fastening member adapted to pivot in the cavity, the fastening member including a recessed portion formed on its underside facing the cavity, the recessed portion being adapted to put on the protrusion, a first threaded hole formed and extended from the recessed portion through the fastening member to expose on a top of the fastening member; and
a fastener driven through the first threaded hole, the recessed portion, and the projection into the central opening to threadedly secure to a second threaded hole extended from a top of the protrusion into the protrusion such that the fastening member is secured to the top of the protrusion, and the connection member and the support are movably disposed between the protrusion and the fastening member.
4. The holder of claim 3, wherein the adjustment member comprises a ring-shaped body, a third through hole formed through the body, a threaded section formed around an inner surface of the third through hole, the threaded section adapted to threadedly secure to outer threads formed below the protrusion and above the other end of the arm, and a plurality of arcuate protuberances formed around the body.
5. The holder of claim 2, further comprising a friction sheet sandwiched between the connection member and the support, the friction sheet including an opening for permitting the fastener to pass the friction sheet.
6. The holder of claim 1, wherein the arm is shaped as a coil and is adapted to flex toward one of a plurality of directions.
7. The holder of claim 1, wherein the adhering member comprises:
a suction cup formed on a bottom of the seat for adhering the holder a supporting surface;
