Abstract
Abstract An apparatus for taking blood samples which involves strapping a blood collector tube to the part of the body from which the sample is to be taken. The blood collector tube has a resilient collapsible funnel which, when compressed, allows a lancet to puncture the dermis and epidermis. A striker member is placed on the end of the tube and a piston, normally held in a spring compressing position by a latch is released thus allowing the spring to impact on the base of the tube, compressing the funnel member and allowing the lancet to puncture the skin.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
191 words
A device for collecting a percutaneous digital blood sample from infants and the like comprising the combination of a tubular body closed at one end and open at the other end and adapted to collect the blood, a funnel member having a resilient funnel portion and a discharge end and engaged at said discharge end in the open end of said body and a mass of absorbent material located within said funnel portion, and at least one incisor lancet in said funnel portion projecting through and beyond said mass and located wholly within said funnel member, said funnel member providing an open passage from said funnel portion to the interior of said tubular body to allow for blood flow, flexible strap means connected to said tubular body below said funnel member for securing the funnel portion to a human body, and elongated striker means receiving the closed end of said tubular body and coaxial therewith, said striker means including a biased striker member and a means to release said member to allow it to impart a longitudinal force to the closed end of said tubular body to obtain a blood sample.
Claim 2
Independent Claim
191 words
A device for collecting a percutaneous digital blood sample from infants and the like comprising the combination of a tubular body closed at one end and open at the other end and adapted to collect the blood, a funnel member having a resilient funnel portion and a discharge end and engaged at said discharge end in the open end of said body and a mass of absorbent material located within said funnel portion, and at least one incisor lancet in said funnel portion projecting through and beyond said mass and located wholly within said funnel member, said funnel member providing an open passage from said funnel portion to the interior of said tubular body to allow for blood flow, flexible strap means connected to said tubular body below said funnel member for securing the funnel portion to a human body, and elongated striker means receiving the closed end of said tubular body and coaxial therewith, said striker means including a biased striker member and a means to release said member to allow it to impart a longitudinal force to the closed end of said tubular body to obtain a blood sample.
Claim 3
Dependent Claim
35 words
A device according to claim 1, and including a capillary tube forming an extension of said funnel member and said passage and extending to a location adjacent to the closed end of the tubular body.
Claim 4
Dependent Claim
29 words
A device according to claim 2, wherein one end of the capillary tube is located within the discharge end of the funnel member, and is integral with said lancet.
Claim 5
Dependent Claim
28 words
A device according to claim 1 and including a base plate supported in a lower part of said funnel portion, said lancet being integral with said base plate.
Claim 6
Dependent Claim
29 words
A device according to claim 1, including means for allowing entrapped air to vent from said tubular body comprising a passage located in the discharge end of said funnel.
Claim 7
Dependent Claim
111 words
A device according to claim 1 where said striker means includes a tubular aperture receiving the closed end of said tubular body, said striker member comprising a striker piston rod, spring means normally biasing said striker piston in a predetermined position, latch means for maintaining said piston in a second position which compresses at least a portion of said spring means, said latch means adapted to be released by a user to allow said compressed spring means to impart a velocity to said piston to effect an impact with the closed end of said tubular body to collapse said funnel portion and allow said lancet to penetrate into a human body.
Claim 8
Dependent Claim
72 words
A device according to claim 6 wherein said spring means comprises two opposed compression springs, said springs acting to maintain said piston in said predetermined position, one spring being weaker than the other which is compressed when said striker piston is withdrawn to allow the velocity imparted by said compressed spring to said piston to overcome said weaker spring thus allowing said piston to impact the closed end of said tubular body.
Claim 9
Dependent Claim
19 words
A device as in claim 1 wherein said tubular body has a magnetizable layer on the body surface thereof.
