Embodiment Construction
[0040] like figure 1 , 2 As shown, a device for measuring the dust production of pharmaceutical granules includes a main body, a rotating motor 3 and a rotating bottle 13, and the rotating motor 3 is mounted on the main body; the main body consists of a machine head 1, a column 16 and a base 8 Composition; the dust sampler 6 is fixed on the base 8, one end of the dust suction pipe 4 is connected to the air inlet 5 of the dust sampler 6, the other end of the dust suction pipe 4 is put into the rotating motor 3, and the suction Dust pipe 4 is fixed tightly, then the filter membrane 12 after weighing is inserted into one end of dust suction pipe, and glass joint 14 is loaded onto, is fixed tightly with screw cap 11.
[0041] The spinner bottle 13 is connected with a glass joint 14 .
[0042] The filter membrane 12 is an air filter membrane with a diameter of φ25mm˜φ50mm, made of glass fiber, polypropylene fiber, plastic or polyester.
[0043] The dust sampler 6 samples at a c...

Abstract
A device for determination of the dust production amount of drug granules comprises a main body, a rotary motor (3) and a rotary bottle (13); the rotary motor (3) is mounted on the main body; the main body comprises a machine head (1), a stand column (16) and a base (8); a dust sampler (6) is fixed on the base (8); one end of a dust sucking pipe (4) is connected with a gas inlet (5) of the dust sampler (6), the other end of the dust sucking pipe (4) is mounted into the rotary motor (3), a sealing rubber ring (15) is used for fixing the dust sucking pipe (4) tightly, then a filter membrane (12) after being weighed is inserted into one head of the dust sucking pipe, a glass joint (14) is mounted, and then a screw cap (11) is used for fixing the glass joint tightly. The device can detect the dust amount of drug granule samples generated due to friction and collision in a state of motion while general dust testers cannot detect the dust amount. Therefore, development and production of the drug granules can be well guided.
Description
technical field [0001] The invention relates to the field of medicine, in particular to an instrument for measuring the dust production of drug granules. Background technique [0002] The traditional Chinese medicine granule itself is a new type of medicine derived from the traditional Chinese medicine decoction. Problems such as boiling and inconvenient carrying. In addition, when necessary, Chinese medicine granules can also be directly coated to improve the stability of the drug itself, avoid the emission of unpleasant medicinal smell, and at the same time alleviate the effect of drug dilution. [0003] Traditional Chinese medicine granules are a new form of traditional Chinese medicine developed on the basis of decoctions. It not only maintains the advantages of fast absorption and rapid effect of decoctions, but also overcomes the time-consuming and energy-consuming and long-term storage of decoctions before taking decoctions. Defects such as easy mildew and deteriora...
