An inhaler for producing an inhalable aerosol of a powdered medicament includes an aerosolizing device in the form of a vortex chamber (). The vortex chamber () has a curved wall (), a tangential inlet port () and an axial exit port (). The radius R of the vortex chamber () decreases with angular extend &#x3b8;. The reduction in effective cross-sectional area of the vortex chamber accelerates the gas flow between the inlet () and the outlet () to reduce deposition of the medicament.

Assymetric inhaler

A method and apparatus for producing a sterile medical solution is disclosed. The method includes providing at least two components, a first component including bicarbonate ions and a second component including glucose or calcium ions, preheating the first component to a first temperature and the second component to a second temperature, heat sterilizing the first and second components separately to a third and fourth temperatures respectively, the third and fourth temperatures being sterilizing temperatures for the first and second components, maintaining the first and second components approximately at their respective third and fourth temperatures, so as to sterilize the first and second components, cooling the first and second components and delivering the first and second components to a mixing device.

Method and apparatus for producing a sterile fluid

Methods and apparatus for sterilizing heat sensitive fluids are provided. The methods include providing a first heat sensitive fluid component, providing a second fluid component, heating the second fluid component to a temperature greater than a predetermined sterilizing temperature, mixing the first heat sensitive fluid component with the heated second fluid component to heat the first heat sensitive fluid components and provide a mixed fluid at a temperature at least up to the predetermined sterilizing temperature, and maintaining the mixed fluid at that temperature for a predetermined sterilizing period. Apparatus for carrying out this method is also provided.

Method and apparatus for sterilizing a heat sensitive fluid

Methods and apparatus for measuring the concentration of decomposable substances, such as urea, are disclosed. The disclosed methods include adding a gaseous buffer, such as CO , to the solution containing the decomposable compound, measuring the conductivity of the solution, decomposing the decomposable compound, measuring the conductivity of the thus-decomposed compound solution, and calculating the differential conductivities between the two measured solutions. The apparatus for carrying out these methods are also disclosed.

Apparatus for measuring a decomposable compound in solution

Methods and apparatus for measuring electrical parameters of a test fluid are disclosed. The methods include maintaining the test fluid and a reference fluid at the same temperature and in thermal proximity to each other, equalizing the temperature of the test fluid and the reference fluid prior to the measuring step, measuring the electrical parameter of the test fluid and the reference fluid at substantially the same time, and standardizing the measurement to a predetermined temperature. The apparatus includes a heat exchanger for maintaining the flow of a primary heat exchange fluid in thermal proximity to the test fluid in the reference fluid, and a metal wall having one surface in contact with a measuring cell and another surface in contact with the flow of the primary heat exchange fluid whereby the measuring cell and the heat exchanger are separated thereby.
