摘要:
A device for administering a powdery medicine satisfying the requirements of portability, easy and quick operation, fabrication through simple steps, rigid structure, and economy using decreased number of parts of low cost. The device for administering a powdery medicine comprises a medicine-holding portion having at least partly flexible wall portion for defining therein a powdery medicine-container space which also serves as an air reservoir, and a medicine guide portion through which the space in said medicine-holding portion is communicated with the outside, wherein the space in said medicine-holding portion is communicated with the outside through said medicine guide portion only, said medicine guide portion is of a tubular structure having, at one end thereof, a medicine spray port at a position on the outside of said medicine-holding portion and having, at the other end thereof, a medicine suction port at a position in the space in said medicine-holding portion, the bottom of the space in said medicine-holding portion is positioned nearly just under the medicine suction port of said medicine guide portion, said medicine suction port is disposed close to said bottom, and the powdery medicine is sprayed to the outside through said medicine guide portion by depressing and relaxing the flexible wall portion of said medicine-holding portion.
摘要:
This invention is concerned with a composition for solid pharmaceutical preparations of active vitamins D.sub.3, having the remarkably improved stability of active vitamins D.sub.3, and an extremely advantageous process for the preparation thereof from the industrial viewpoint. The composition of this invention is a composition for solid pharmaceutical preparations of active vitamins D.sub.3 prepared by forming an outer layer comprising active vitamins D.sub.3 and an excipient, which is readily soluble in an organic solvent, around an inner layer comprising an excipient which is slightly soluble in an organic solvent.
摘要:
An administering device capable of quantitatively spraying a multi-dose of powdered medicine includes a device body (1), a storage chamber (3) detachably provided in the device body, the storage chamber (3) being capable of storing powdered medicine, the amount of which corresponds to a plurality of administering operations, an accommodation chamber (10) capable of accommodating powdered medicine, the amount of which corresponds to a single administering operation, and a medicine dispensing rotor (6) movably attached to the device body. The medicine dispensing rotor communicates the accommodation chamber with the storage chamber at a charging position (3a) and communicates the accommodation chamber with the outside of the device body at an administering position (5a) so that the powdered medicine in the accommodation chamber can be administered. A cap (20) is provided for moving the medicine dispensing rotor between the charging position and the administering position. A pump means (8) is provided for injecting air into the storage chamber through the accommodation chamber at the charging position so that the powdered medicine in the storage chamber can be stirred and a predetermined quantity of powdered medicine that has been stirred can be charged from the storage chamber to the accommodation chamber by the suction force of the pump means and/or gravity.
