Abstract
Abstract A pencil-grip fine needle aspiration syringe holder for accurately placing a needle into a region using a single hand disposed close to the needle tip in a position of natural function, useable with a standard syringe. A body is provided for receiving a syringe barrel, and a slide is movably mounted to the body for engaging a syringe handle, for movement between a withdrawal position where a syringe plunger is in a compact position and a released position where the plunger is in an extended position. A finger engaging member is fixed to the body for grasping the holder in a pencil-grip manner, and a biasing member is coupled between the body and the slide for urging the slide toward the released position and the plunger toward the extended position. A catch is provided for restraining the slide in the withdrawal position and plunger in the compact position, along with a release for releasing the catch to allow the slide to move away from the withdrawal position and towards the released position, decreasing pressure within the syringe. A limit member is situated for limiting movement of the slide and the plunger toward the extended position. An adjustable regulating member is coupled to the limit member for adjusting the position of the limit member relative to the body.

Claim 8
Dependent Claim
70 words
The holder of claim 5, further comprising: a catch for restraining the slide in the withdrawal position and plunger in the compact position; and a release for releasing the catch to allow the slide to move away from the withdrawal position and towards the released position under influence of the biasing member, thereby moving the plunger from the compact position toward the extended position and decreasing pressure within the syringe.
Claim 9
Dependent Claim
45 words
The holder of claim 6 further comprising a limit member situated to intercept the slide between the compact position and the extended position for limiting movement of the slide and the plunger toward the extended position, thereby limiting the low pressure achievable within the syringe.
Claim 10
Dependent Claim
37 words
The holder of claim 7 further comprising an adjustable regulating member coupled to the limit member for adjusting the position of the limit member relative to the body thereby adjusting the low pressure achievable within the syringe.
Claim 11
Dependent Claim
159 words
A holder for a fine needle aspiration syringe, the syringe having a barrel, a plunger including a handle, and a needle disposed generally opposing the handle, the plunger movable within the barrel between a compact position and an extended position, the holder comprising: a generally elongated body for receiving the barrel, having a first end and a second end, and adapted to be held in the manner of a pencil between a thumb and forefinger with the first end proximate to the handle and the second end proximate to the needle; a slide movably mounted with respect to the body for engaging the handle, capable of movement between a withdrawal position where the plunger is disposed in the compact position and a released position where the plunger is disposed in the extended position; and a biasing member coupled between the body and the slide for urging the slide toward the released position and the plunger toward the extended position.
