  • Publication number: 20240165318
    Abstract: A negative pressure wound therapy device can include one or more fluid detection systems. A canister fluid level detection system can incorporate various fluid detection devices to communicate data relating to the fluid level of the canister. In some cases, a negative pressure wound therapy device can include a device housing, a negative pressure source, and a canister configured to be in fluid communication with the negative pressure source. The canister can include a canister housing configured to store fluid aspirated from a wound, a cap connected to the canister housing, and a fluid level sensor supported by the cap. The fluid level sensor can be configured to detect a completed electrical circuit when the fluid aspirated from the wound comes into contact with the sensor. An electronic circuitry can be configured to detect a state of the sensor and provide an indication of a status of the canister.

  • Patent number: 7741044
    Abstract: A method of making a set of labelled compounds by the use of a preferably particulate support, comprises dividing the support into lots, performing a different chemical reaction on each lot of the support, e.g. to couple a chemical moiety to that lot of the support, tagging a fraction of each lot of the support with a different label, and combining the said lots of the support. The steps are repeated several times, preferably to build up oligomer molecules carrying labels which identify the nature and position of a monomer unit of the oligomer, and which are releasable from the support. Preferred labels, which are releasable from the compounds by cleavage to provide charged groups for analysis by mass spectrometry, are groups of the trityl (trimethylphenyl) family. Also claimed are libraries of these labels and their use in assays and nucleic acid analysis methods.
