Abstract
Abstract The invention relates to a device for inserting a hollow coupling member into the bone marrow of man or animals. Fluid may be supplied to the bone marrow through the inserted coupling member. The device according to the invention comprises an assembly of a striker-pin holder, a striker pin and a coupling member which is movably accommodated in an elongate housing and on which a force can be exerted by a source of energy provided in the device. When this force is exerted the striker pin and the coupling member are driven into the bone marrow, whereupon the coupling member can be detached from the remainder of the device.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
166 words
A device for inserting coupling means into human or animal bone marrow, comprising an elongated housing, a striker pin holder mounted within said housing for axial displacement, a substantially hollow coupling member having a pointed part and a central bore, said coupling member arranged within said housing adjacent said striker pin holder, a striker pin made of a hard material connected to said striker pin holder for movement therewith and extending through the central bore of said coupling member and beyond the end thereof, means at one end of said housing permitting passage therethrough of at least a part of said striker pin, a source of potential energy for exerting a force on said striker pin holder when released so as to cause movement thereof and drive said coupling member and said striker pin through the end of said housing and into the bone marrow when said device is placed on the surface of the skin of a patient and means for releasing said potential energy.
Claim 2
Independent Claim
166 words
A device for inserting coupling means into human or animal bone marrow, comprising an elongated housing, a striker pin holder mounted within said housing for axial displacement, a substantially hollow coupling member having a pointed part and a central bore, said coupling member arranged within said housing adjacent said striker pin holder, a striker pin made of a hard material connected to said striker pin holder for movement therewith and extending through the central bore of said coupling member and beyond the end thereof, means at one end of said housing permitting passage therethrough of at least a part of said striker pin, a source of potential energy for exerting a force on said striker pin holder when released so as to cause movement thereof and drive said coupling member and said striker pin through the end of said housing and into the bone marrow when said device is placed on the surface of the skin of a patient and means for releasing said potential energy.
Claim 3
Dependent Claim
42 words
The device according to claim 1 further comprising a shoulder within said housing for acting as a stop for the striker pin holder so as to limit its axial movement and depth of penetration of said coupling member into said bone marrow.
Claim 4
Dependent Claim
58 words
The device according to claim 1 further comprising an auxiliary member connected to said elongated housing at the end thereof permitting passage of said striker pin for determining the depth of penetration of said coupling member into the bone marrow, said auxiliary member having at least one pointed projection extending therefrom for penetrating the skin of the patient.
Claim 5
Dependent Claim
34 words
The device according to claim 3 wherein said auxiliary member comprises an internally thickened portion of said elongated housing being integral therewith and located at the end thereof permitting passage of said striker pin.
Claim 6
Dependent Claim
36 words
The device according to claim 3 wherein said auxiliary member comprises a cover detachably secured to said housing having a central opening through which said striker pin and pointed part of said coupling member can pass.
Claim 7
Dependent Claim
40 words
The device according to claim 3 wherein said auxiliary member comprises a cover detachably secured to said housing the center thereof being made of a material through which said striker pin and pointed part of said coupling member can pass.
Claim 8
Dependent Claim
87 words
The device according to claim 3 wherein said auxiliary member comprises a tablelike element having legs with cutting edges, said element being detachably connected to said elongated housing at the end thereof permitting passage of said striker pin, means for detachably connecting the element to said housing comprising cooperating coupling parts on said element and said housing, and a recess in said element in the surface thereof facing away from said legs forming a passage for the striker pin and the pointed part of said coupling member.
Claim 9
Dependent Claim
41 words
The device according to claim 7 further comprising a tapered sawtooth screwthread at the end of said pointed part of said coupling member, the direction of said screwthread being opposite to the direction of said coupling part of said tablelike element.
Claim 10
Dependent Claim
45 words
The device according to claim 1 further comprising an auxiliary member connected to said coupling member for determining the depth of insertion thereof into the bone marrow, said auxiliary member having a plurality of pointed projections extending therefrom for penetrating the skin of the patient.
Claim 11
Dependent Claim
29 words
The device according to claim 9 wherein said auxiliary member comprises a stylet connected to said coupling member having at least one wing-like projection provided with a cutting edge.
Claim 12
Dependent Claim
57 words
The device according tO claim 1 wherein said striker pin holder is substantially cylindrical, said striker pin being centrally secured therein at the lower end thereof, coupling means arranged at the lower surface of said striker pin holder for cooperative engagement with cooperating means on the upper surface of said coupling member to said striker pin holder.
Claim 13
Dependent Claim
23 words
The device according to claim 1 further comprising a tapered sawtooth screwhead at the end of said pointed part of said coupling member.
Claim 14
Dependent Claim
45 words
The device according to claim 1 further comprising at least one projection on the outer surface of said striker pin holder, and a groove on the inner surface of said housing receiving said projection, said groove extending nearly to the open end of said housing.
