The utility model is suitable for the technical field of mineralized water purification, and discloses a filter element, a filter cartridge and a mineral spring water purifier. The filter element comprises a carbon fiber filter body, the carbon fiber filter body comprises at least two mineralized carbon fiber filter layers which are sequentially attached, and the at least two mineralized carbon fiber filter layers are provided with the same or different mineralizer layers. And the mineralized carbon fiber filter body is formed by winding. The filter cartridge comprises a cartridge shell and the filter element, and the filter element is arranged in the cartridge shell. The mineral spring water purifier comprises the filter element or the filter cartridge. The filter element comprises a carbon fiber filter body, the carbon fiber filter body comprises at least two mineralized carbon fiber filter layers which are sequentially attached, and the at least two mineralized carbon fiber filter layers are provided with different mineralizers, so that different use requirements are met, and the water body contains mineral components beneficial to human health; and high-end requirements of users on drinking water beneficial to health can be met.

The application discloses a kind of stable indometacin tablets and its preparation process, belong to pharmaceutical preparation technical field.The tablet is composed of indometacin, hydroxypropyl beta-cyclodextrin, soybean phospholipid, composite stabilizer, binder and lubricant, and the composite stabilizer is compounded by succinylated c14-c18 alkyl sulfonate sodium, N-ethyl-L-glutamine and maltodextrin according to specific mass ratio.Preparation process includes liposome inclusion compound preparation, mixing granulation, drying whole particle, total mixing and tabletting.The application realizes the preparation of high drug loading design, and the composite stabilizer forms a multilayer coating protection system with hydroxypropyl beta-cyclodextrin and soybean phospholipid, which synergistically improves the dissolution performance and stability of the preparation, makes the dissolution rate of the preparation fast, and the content of the main component decreases little during long-term storage, solves the problems of low drug loading, poor stability and dissolution of existing indometacin tablets.
