Abstract: An apparatus for use in measuring the free chlorine level in a solution of halogenated pool/spa water includes a pH adjusting device for producing a first sample of said solution having a first selected pH and a second sample of said solution having a second selected pH, as well as a spectral analyzer for determining first and second ultraviolet light (UV) transmissivity values for each of the first and second samples. An electronic processor receives the first and second transmissivity values and determines the free chlorine or bromine level using those values.

Abstract: Many of those having diabetes take a combination of slow and fast acting types of insulin. It is important that the different forms of medicament do not become confused. To this end, a medicament cartridge is provided comprising a sleeve having a bottleneck providing a flange at a first end, a fluid impermeable membrane secured across the first end by a metal cap beaded beneath the flange, and a displaceable piston located internally of the sleeve towards a second end of the sleeve, a collar located against an external periphery of the cartridge housing beneath the flange and an adaptor top press fit over the cap and the collar, the adaptor top being provided with means to act upon the collar thereby to retain the adaptor top on the sleeve.

Abstract: A method of measuring chlorine concentration of a solution comprising making a first measurement of transmission of ultraviolet light at a selected wavelength through a first sample of said solution at a first temperature; making a second measurement of the transmission of ultraviolet light at said selected wavelength through a second sample of said solution at a second temperature, said second temperature being different than said first temperature; and determining the chlorine concentration in said solution using the results of said first and second measurements.

Abstract: A method of measuring the free chlorine level in a solution of chlorinated pool/spa water comprises a first sample of said solution having a first selected pH and a second sample of said solution having a second selected pH and determining first and second ultraviolet light (UV) transmissivity values for each of the first and second samples. The first and second transmissivity values are then used to determine the free chlorine level.

Abstract: A sock suitable for wearing on a limb of a patient, the sock comprising material having the ability to wick moisture away from the skin surface and the sock comprising padding located in those areas of the sock which in use will cover the ankle and shin of the patient.

Abstract: A compression device for a limb of a patient comprises an inflatable sleeve arranged to surround the limb and a conduit attached to the sleeve arranged to deliver fluid to the sleeve. The compression device also comprises a control system arranged to control fluid flow in the device and a memory arranged to store gathered data relating to use of the device.

Abstract: Many of those having diabetes take a combination of slow and fast acting types of insulin. It is important that the different forms of medicament do not become confused and that the patient does not receive the incorrect medicament. In combination a medicament delivery apparatus and a medicament cartridge are provided, the medicament delivery apparatus including at least one switch and the medicament cartridge comprising a cartridge housing within which a medicament is provided, a displaceable piston located internally at one end of the housing and a raised ring of material about an external periphery of the medicament cartridge, the ring of material being of sufficient dimensions, in use, to trip the at least one switch of the medicament delivery apparatus.

Abstract: Provided, in one embodiment, is a vacuum wound dressing for covering a wound bed comprising: a wound contact layer comprising a fibrous blend or fibrous material that forms a cohesive gel when wetted by wound exudate; a source of vacuum situated to be separated from the wound bed by the wound contact layer; and a vacuum sealing layer covering the wound contact layer and adapted to retain relative vacuum in the wound contact layer, wherein (i) the dressing is essentially missing a non-gelling, foam layer in which the source of vacuum is situated or (ii) the vacuum sealing layer comprises as an outer layer a foam layer.
