Abstract
Abstract A blood sampling instrument for drawing a few drops of blood from a finger or the like by needle 27 in holder 25, is provided wherein the sample device consists primarily of a tubular member 5 which conceals all of the working parts and which has a flange 9 thereon so that it can be easily held by a patient and pressed at 17 against a finger while releasing a trigger mechanism 57,33 to actuate a plunger 21, biassed by spring 37, within the instrument. The instrument can be cocked ready for use by pulling back a retractable outer sleeve 47.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
209 words
A blood sampling instrument designed to be hand held and being adapted to prick a finger or the like to draw a few drops of blood, comprising in combination: (a) a tubular member having a hollow nosepiece at the distal end and a spring chamber at the proximal end, (b) an annular collar and annular flange immediately behind said nosepiece, (c) a hollow sleeve surrounding said spring chamber, (d) a plunger mounted for reciprocation within said tubular member. (e) a main spring mounted within said spring chamber and biasing said plunger toward said nosepiece, (f) a socket for receiving a needle on the distal end of said plunger, (g) a finger on said plunger to engage an aperture in said tubular member and hold said plunger when said plunger is drawn away from said nosepiece, (h) a trigger button extending from said collar and having means to engage the finger on said plunger, (i)plunger cocking means on said sleeve to pull said plunger away from said nosepiece and engage said finger whereby (j) the nosepiece of said instrument can be pressed against a finger by exerting pressure on said flange while pressing said trigger to release said plunger and cause said needle to be driven out of said nosepiece.
Claim 2
Dependent Claim

A blood sampling instrument designed to be hand held and being adapted to prick a finger or the like to draw a few drops of blood, comprising in combination: (a) a tubular member having a hollow nosepiece at the distal end and a spring chamber at the proximal end, (b) an annular collar and annular flange immediately behind said nosepiece, (c) a hollow sleeve surrounding said spring chamber, (d) a plunger mounted for reciprocation within said tubular member. (e) a main spring mounted within said spring chamber and biasing said plunger toward said nosepiece, (f) a socket for receiving a needle on the distal end of said plunger, (g) a finger on said plunger to engage an aperture in said tubular member and hold said plunger when said plunger is drawn away from said nosepiece, (h) a trigger button extending from said collar and having means to engage the finger on said plunger, (i)plunger cocking means on said sleeve to pull said plunger away from said nosepiece and engage said finger whereby (j) the nosepiece of said instrument can be pressed against a finger by exerting pressure on said flange while pressing said trigger to release said plunger and cause said needle to be driven out of said nosepiece.
Claim 3
Dependent Claim
22 words
The instrument of claim 1 wherein said nosepiece is removably mounted whereby nosepieces of different lengths can be mounted on the instrument.
Claim 4
Dependent Claim
40 words
The instrument of claim 1 wherein said sleeve can be retracted to lie against said shoulder after cocking operation whereby said sleeve will not move when said plunger is released and protects the plunger from contact with the holding hand.
Claim 5
Dependent Claim
36 words
The instrument of claim 3 having a click stop when said sleeve is fully retracted to give an audible and tactile indication that the sleeve is retracted and to restrain the sleeve against easy sliding movement.
Claim 6
Dependent Claim
32 words
The instrument of claim 1 having a bounce back spring on the proximal end of said plunger whereby said needle is drawn back into the nosepiece after intially extending beyond the nosepiece.
