Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
103 words
A method for collecting a given amount of liquid containing radioactive tracer elements from a container which also contains solid particles, in particular biological tissue, without at the same time collecting such particles, comprising the steps of immersing an actively absorbing surface of a liquid absorbent body in said amount of liquid, said surface covered with a filter permeable to said liquid, but not to said particles, completely absorbing said amount of liquid in the liquid absorbent body through said filter, subseqently separating said filter from said actively absorbing surface, and removing the absorbent body from the container after separation of the filter.
Claim 2
Independent Claim
103 words
A method for collecting a given amount of liquid containing radioactive tracer elements from a container which also contains solid particles, in particular biological tissue, without at the same time collecting such particles, comprising the steps of immersing an actively absorbing surface of a liquid absorbent body in said amount of liquid, said surface covered with a filter permeable to said liquid, but not to said particles, completely absorbing said amount of liquid in the liquid absorbent body through said filter, subseqently separating said filter from said actively absorbing surface, and removing the absorbent body from the container after separation of the filter.
Claim 3
Dependent Claim
22 words
A method according to claim 1, wherein the separation of said filter from said surface is accomplished by dissolution with said liquid.
Claim 4
Dependent Claim
25 words
A method according to claim 1, wherein the separation of said filter from said surface is accomplished by mechanically breaking said filter from said surface.
Claim 5
Dependent Claim
154 words
Apparatus for collecting a given amount of liquid containing radioactive tracer elements from a container which also contains solid particles, in particular biological tissue, without at the same time collecting such particles, comprising at least one liquid absorbent body adapted to be immersed in the amount of liquid in the container and having thereon an actively absorbing surface disposed so as to contact said amount of liquid, a filter completely covering said actively absorbing surface, said filter being permeable to said liquid, but impermeable to said particles, and bonding means attaching said filter to said actively absorbing surface, said bonding means being liable to be dissolved under the influence of the liquid present in the container so as to allow separation of said filter from said actively absorbing surface subsequent to the complete absorption of the amount of liquid by said body through the filter, but before said body is removed from the container.
Claim 6
Dependent Claim
154 words
Apparatus for collecting a given amount of liquid containing radioactive tracer elements from a container which also contains solid particles, in particular biological tissue, without at the same time collecting such particles, comprising at least one liquid absorbent body adapted to be immersed in the amount of liquid in the container and having thereon an actively absorbing surface disposed so as to contact said amount of liquid, a filter completely covering said actively absorbing surface, said filter being permeable to said liquid, but impermeable to said particles, and bonding means attaching said filter to said actively absorbing surface, said bonding means being liable to be dissolved under the influence of the liquid present in the container so as to allow separation of said filter from said actively absorbing surface subsequent to the complete absorption of the amount of liquid by said body through the filter, but before said body is removed from the container.
Claim 7
Dependent Claim
33 words
Apparatus according to claim 4, wherein said absorbent body is comprised of opaque materials so as to be adapted to scintillation counting of gamma radiation from said tracer elements in the absorbed liquid.
Claim 8
Dependent Claim
33 words
Apparatus according to claim 4, wherein said absorbent body is comprised of transparent materials so as to be adapted to scintillation counting of beta radiation from said tracer elements in said absorbed liquid.
Claim 9
Dependent Claim
51 words
Apparatus according to claim 4, wherein a plurality of absorbent bodies are mounted on a common base in a pattern corresponding to a like number of containers mounted in a frame to allow simultaneous collection of liquid from each of the containers by means of an associated one of said bodies.
