Needle insertion assistance device
First Claim
1. A needle insertion assistance device for use with a needle device, the needle device including a syringe and a needle that has a needle wing and is attached to the syringe, the needle insertion assistance device comprisinga base having a front end, a rear end, an underside, and a top surface having two sides and a rear part, to support the needle device on the top surface;
- a supporting plate having a front surface for contacting the skin of a patient, and an oppositely facing rear surface to support the needle insertion assistance device and prevent unintentional forward advancement of the needle insertion assistance device;
a handle securely affixed to the underside of the base for a user to hold and use the needle insertion assistance device;
a means for connecting the front end of the base to the rear surface of the supporting plate; and
a means for holding the syringe of the needle device on the base;
wherein the means for connecting the front end of the base to the rear surface of the supporting plate connects the front end of the base to the rear surface of the supporting plate along a line wherein a substantial portion of the oppositely facing surface of the supporting plate lies above the line and a substantial portion of the oppositely facing surface of the supporting plate lies below the line, wherein the line is parallel to the front end of the base and perpendicular to a longitudinal axis of the base, and wherein the supporting plate extends longitudinally a first distance above the line and perpendicular to the line in a first direction, and extends longitudinally a second distance below the line and perpendicular to the line in a second direction opposite the first direction, such that the first distance and the second distance are approximately equal;
wherein the means for connecting the front end of the base to the rear surface of the supporting plate connects the front end of the base to the rear surface of the supporting plate so that the base can pivot with respect to the supporting plate;
wherein the top surface of the base is substantially planar, and the rear surface of the supporting plate is substantially planar, and the means for connecting the front end of the base to the rear surface of the supporting plate allows the base to be pivoted with respect to the supporting plate, so that the top surface of the base can be oriented at angles substantially different from ninety degrees with respect to the rear surface of the supporting plate.

Abstract
A needle insertion assistance device is provided to easily hold a needle device, which comprises a syringe and a needle having a needle wing and being attached to the syringe, in order to more reliably control the advancement of the needle during insertion of the needle into a targeted part of a human body for many medical purposes. One embodiment of the needle insertion assistance device may comprise a supporting plate, a base connected hingedly to a rear surface of the supporting plate, and a syringe holder securely affixed to a top surface of the base to slidably hold the syringe on the base and prevent the syringe from moving from side to side. This embodiment of the needle insertion assistance device may further include a needle blocker, a handle, and an angle adjusting assembly.
