A review of automated homeopathic prescribing systems.
This paper reviews the design and function of an automated homeopathic prescribing system and examines its potential to fulfill some of the requirements of a modern, clinical pharmacy service. Two parallel prescriptions can be prepared by means of a computer interface with an interactive video display and audio system. The first is a computer-generated prescription for treatment of an acute condition based on the clinician's judgement and is suitable for a short duration of care. The second prescription is a standardised homeopathic treatment, and although limited by the choice of fixed treatment, its adoption can provide feedback on the use of homeopathic remedies in everyday practice.The present invention relates to a method of producing polytetrafluoroethylene fine powder of a desired shape, and more particularly to a method of producing polytetrafluoroethylene fine powder of a desired shape, in which a method for manufacturing hexagonal polytetrafluoroethylene fine powder of high concentration by the gas phase polymerization of tetrafluoroethylene is improved to obtain high concentration hexagonal polytetrafluoroethylene fine powder having high bulk density.
As a production method of hexagonal polytetrafluoroethylene fine powder, a method is known in which a powder of a polymer material obtained by a dispersion polymerization of tetrafluoroethylene is subjected to homogeneously mixed polymerization or melt-extrusion polymerization by means of a liquid phase using a radical initiator to obtain a polymer fine powder which is granulated and then classified (see JP-A-5-82214).
In the method, when the powder of the polymer material obtained by the dispersion polymerization is melt-extruded, the powder is melt-extruded by the means of an extruder in a liquid phase of a specific composition, and then after the extruded powder is dried, the resultant dried powder is subjected to melt-extrusion polymerization by means of an extruder so as to obtain a polytetrafluoroethylene fine powder. In this method, as a method of preparing a powder of the polymer material of the polymer fine powder, a method is known in which a dispersion liquid of tetrafluoroethylene which is a polymerization reactant and a dispersion medium is prepared and the dispersion liquid is dispersed in a solvent (see U.S. Pat. No. 5,141,986).
