  • Patent number: 8460863
    Abstract: A method of preparing a dry stick test device for determining an analyte in a milk sample by chemical assay. At least one reagent pad is provided by impregnating a first porous material with an aqueous solution including a reagent capable of reacting with the analyte, a derivative of the analyte or an indicator compound for the analyte to provide a detectable signal when in a moistened state. The reagent pad is dried. A development pad is provided by impregnating a second porous material with an aqueous solution including at least one controlling compound which, when in a moistened state, is capable of providing a condition required for the reagent to react with the analyte to provide the detectable signal. The impregnated second porous material is dried. The first porous material is immobilized with the second porous material, on a solid support, to obtain the dry stick test device.

  • Patent number: 8262991
    Abstract: The present invention relates generally to an apparatus for analysing fluid taken from a body, and more in particularly for analysing body fluids from mammals. The analysis apparatus is coupled to a dairy system for milking of cows, wherein it may be useful to analyse the status of the milk. The apparatus is preferably located as early as possible in the production chain in order to obtain results as close as possible to the cows. Hence the environment in which the apparatus is to be used may be harsh towards internal apparatus modules or consumables, therefore the apparatus is isolated and the internal environment is conditioned regarding humidity, temperature as well as the amount of ammonium. Furthermore the steps for analysing milk is automated inside the apparatus in order to avoid influence from the external environment.

  • Patent number: 8216524
    Abstract: A testing device for testing or analysing fluids comprises a separately produced holder (10) and a sheet-or plate-like test member (11) including analysis reagent. The holder defines an abutment surface (13) for engaging with a side surface of the test member. Projections (15) formed on the holder are positioned and shaped so as to allow insertion of the test member into the holder by moving the test member into engagement with said abutment surface while engaging with opposite edge portions thereof. The projections may, for example, be tooth-shaped and have pointed ends, and at least some of the projections may have a leading edge (16) forming a ramp sloping towards a plane defined by the abutment surface so as to facilitate insertion of the test member into the holder. A stack of such testing devices may be arranged within a cassette from which they may be fed successively into an automatic analyser. The holder of the testing device may be re-used.

  • Patent number: 7690328
    Abstract: The invention relates to a milk conveyer device (100) for an animal. The milk conveyer device is to be implemented in a milking arrangement which comprises a milk storage reservoir (101) coupled to a milking attachment for attaching to an animal to be milked through a main milk conduit (103, 105). A sample element (109, 111) extracts milk, which is collected in a sample reservoir (115, 117). The sample reservoir (115,117) is connected to an analysis element (129) through an analysis conduit (123, 125). During the flow of the milk from the sample reservoir to the analysis element (129), the milk itself provides a cleaning effect. The flow is initially at a high flow rate and later at a reduced flow rate. A plurality of analysis conduits (123, 125) are connected to the analysis element (129), which comprises a selector unit (127), which couples milk from one of the analysis conduits (123, 125) to the analysis element (129).

  • Patent number: 6814025
    Abstract: A system for optimising the production performance of a milk producing animal herd is provided. The system comprises a milk sampling apparatus, an analytical apparatus comprising separate equipment for analyzing compounds or parameters that in the presence of compounds indicative of the physiological or nutritional condition of the herd member, generates detectable signals, and apparatus directing a part of the milk sample (directing apparatus) to each separate equipment, which is controlled by data for the physiological and nutritional state of a herd member, so that the directing apparatus is only activated at pre-selected points in time or at pre-selected time intervals in the production and/or lactation cycles. Specific compounds are compounds indicative of mastitis, including beta-N-acetylhexosaminidase (NAGase) E.C. 3.2.1.
