Abstract
Abstract A tattooing device comprises a needle carrier (1) having a plurality of hollow needles (2), an exchangeable program carrier (11,26,31,39) and control means having a jaw (7). The program carrier has an assembly of cylindrical cavities (13,28,33,40) with a fluid (23), each of which can be put into open communication with a needle, in which cavities pistons (6,18,34,38) are movable for pressing out the fluid and which cavities are at least partly closed at an axial end by a closing element (18,29,34,41) in dependence on the force exerted by the jaw for transfer to the needle. The closing element is at least partly deformable, the deformation of the closing element requiring a heavier force than that required for inserting the needle into the tissue so that owing to the force exerted by the jaw on the program carrier first the needle is inserted into the tissue and subsequently by the deformation of the closing element the piston can move into the cavity.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
234 words
A tattooing device for marking animals by the device of a contrasting fluid into tissue of the animal, said device comprising: a needle carrier; a plurality of hollow needles carried by said needle carrier, said needles being arranged in a matrix capable of forming marking symbols from combinations of selected ones of said needles, said needles being movable with respect to said needle carrier to an extended position for insertion into the tissue of the animal; an exchangeable program carrier having a plurality of cavities containing the contrasting fluid and alignable with selected ones of said needles; and operating means receiving said needle carrier and program carrier for relatively moving said program carrier and needle carrier toward and away from each other; said cavities containing the contrasting fluid being at least partly closed by a closing element, the movement of said program carrier and said needle carrier toward each other bringing said needles into abutment with said program carrier to extend said selected ones of said needles for insertion in the tissue of the animal to be marked, said closing elements being at least partially deformable by the relative movement of said program carrier and needle carrier for injecting the contrasting fluid from said cavities through said extended needles into the animal tissue, the deformation of the closing elements requiring a greater force than that required to insert the needles into the animal tissue.
Claim 2
Dependent Claim
234 words
A tattooing device for marking animals by the device of a contrasting fluid into tissue of the animal, said device comprising: a needle carrier; a plurality of hollow needles carried by said needle carrier, said needles being arranged in a matrix capable of forming marking symbols from combinations of selected ones of said needles, said needles being movable with respect to said needle carrier to an extended position for insertion into the tissue of the animal; an exchangeable program carrier having a plurality of cavities containing the contrasting fluid and alignable with selected ones of said needles; and operating means receiving said needle carrier and program carrier for relatively moving said program carrier and needle carrier toward and away from each other; said cavities containing the contrasting fluid being at least partly closed by a closing element, the movement of said program carrier and said needle carrier toward each other bringing said needles into abutment with said program carrier to extend said selected ones of said needles for insertion in the tissue of the animal to be marked, said closing elements being at least partially deformable by the relative movement of said program carrier and needle carrier for injecting the contrasting fluid from said cavities through said extended needles into the animal tissue, the deformation of the closing elements requiring a greater force than that required to insert the needles into the animal tissue.
Claim 3
Dependent Claim
23 words
A tattooing device as claimed in claim 1 wherein said program carrier includes at least one cavity not provided with a closing element.
Claim 4
Dependent Claim
101 words
A tattooing device as claimed in claim 1 wherein said closing elements are formed as pistons for said cavities containing the contrasting fluid, said pistons being abuttable with said selected ones of said needles when said program carrier and needle carrier are moved toward each other for extending said needles, each of said pistons having an internal fluid channel alignable with one of said needles and an external deformable peripheral element by which the piston is positioned across the cavity, deformation of said peripheral element permitting movement of said piston into the cavity for pressing the fluid out of the cavity.
Claim 5
Dependent Claim
31 words
A tattooing device as claimed in claim 3 wherein said pistons are integrally formed with the program carrier through a deformably breakable connection of the peripheral element to the program carrier.
Claim 6
Dependent Claim
26 words
A tattooing device as claimed in claim 3 wherein the peripheral element of said pistons is formed by a shoulder about the exterior of the piston.
Claim 7
Dependent Claim
26 words
A tattooing device as claimed in claim 3 wherein at least one of said pistons has a recess surrounding said fluid channel for receiving a needle.
Claim 8
Dependent Claim
24 words
A tattooing device as claimed in claim 3 wherein at least one of said pistons has a fluid channel conically narrowing toward the needle.
Claim 9
Dependent Claim
25 words
A tattooing device as claimed in claim 1 wherein said closing element comprises a deformable foil-like layer extending across the cavities containing the contrasting fluid.
Claim 10
Dependent Claim
79 words
A tattooing device as claimed in claim 8 wherein the cross sectional area of ends of said needles abutting the program carrier corresponds to the cross sectional area of the cavities, said cross sectional areas being taken normal to the direction of needle extension, wherein said foil-like layer is abuttable with said ends of said needles for deformation and perforation, and wherein said ends of said needles act as pistons in said cavities for pressing out the contrasting fluid.
Claim 11
Dependent Claim
37 words
A tattooing device as claimed in claim 8 wherein said operating means carries pistons appliable to said foil-like layer and movable in said cavities upon the deformation of said foil-like layer for pressing out the contrasting fluid.
Claim 12
Dependent Claim
28 words
A tattooing device as claimed in claim 3 wherein the piston has a greater dimension than the cavity to form the external deformable peripheral element of the piston.
Claim 13
Dependent Claim
27 words
A tattooing device as claimed in claim 1 wherein said program carrier has a foil-like layer spanning said cavities for retaining the contrasting fluid in the cavities.
