Abstract

Abstract A sampling device for obtaining a plurality of milk samples from the teats of a cow, the device comprising a body with sockets to receive the ends of tubes connected to teat cups, passages in the body connecting the sockets with individual sample cuvettes and a common valve member for opening or closing the passages between the sockets and the sample cuvettes. An overflow passage is provided upstream of the valve member for disposal of excess milk.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 160 words
A sampling device for use in sampling of biological fluids such as milk including: a sampling block containing a plurality of sample passages, each sample passage being provided with an overflow port capable of draining away excess sample fluid from the sample passage; connection means interposed between each sample passage and an associated sampling location of a body of an animal; and valve means common for each sample passage for ensuring that flow of sample fluid in each sample passage occurs simultaneously, said common valve means including a valve stem located in a mating passage in the sampling block which is transverse to the axis of each sample passage and said valve stem having a plurality of openings wherein each opening may be aligned upon rotation of the valve stem with an associated sample passage when in the open position so as to allow sample fluid to flow through each sample passage; and collection means associated with each sample passage.
Claim 2
Dependent Claim 160 words
A sampling device for use in sampling of biological fluids such as milk including: a sampling block containing a plurality of sample passages, each sample passage being provided with an overflow port capable of draining away excess sample fluid from the sample passage; connection means interposed between each sample passage and an associated sampling location of a body of an animal; and valve means common for each sample passage for ensuring that flow of sample fluid in each sample passage occurs simultaneously, said common valve means including a valve stem located in a mating passage in the sampling block which is transverse to the axis of each sample passage and said valve stem having a plurality of openings wherein each opening may be aligned upon rotation of the valve stem with an associated sample passage when in the open position so as to allow sample fluid to flow through each sample passage; and collection means associated with each sample passage.
Claim 3
Dependent Claim 40 words
A sampling device as claimed in claim 1 wherein each sample passage is cylindrical in cross section and of uniform diameter and is rectilinear with each other so that a row of sample passages are located in the sampling block.
Claim 4
Dependent Claim 34 words
A sampling device as claimed in claim 1 wherein the orientation of each overflow port is such that it projects downwardly at an angle relative to the longitudinal axis of the adjacent sample passage.
Claim 5
Dependent Claim 29 words
A sampling device as claimed in claim 1 wherein the collection means includes a plurality of collection vessels mounted on a common stand or frame below the sampling block.
Claim 6
Dependent Claim 21 words
A sampling device as claimed in claim 4 wherein the common stand or frame is releasably attached to the sampling block.
Claim 7
Dependent Claim 48 words
A sampling device as claimed in claim 1 wherein the connection means includes connection tubes or hoses formed from flexible material which may at one end engage or be located adjacent a respective teat of a cow and at the other end engage with an associated sample passage.
