Abstract: The invention relates to the technical field of medicines, and particularly relates to a multi-component injection and preparation processes and applications thereof. In the present invention, the effective ingredients of safflower Carthamus, Red Paeony Root, Ligusticum wallichii, Radix salvia miltiorrhizae and Angelica sinensis are analyzed and a multi-component injection is prepared via the modem pharmaceutical preparation technology. The study proves that the multi-component injection of the invention has therapeutic effects on Sepsis.

Abstract: The embodiments of the disclosure discloses an cavity filter in which a sealed resonant cavity is formed by using an adjusting end cover and a body, and a positional relationship between the resonator and the adjusting end cover is changed by using a deformable adjusting end cover. Therefore, during the adjustment of the performance parameters of the cavity filter, the resonant cavity may be kept clean, so as to prevent metal debris or external dust from entering the resonant cavity and affecting the filtering performance of the cavity filter. The adjusting end cover is configured to be driven by the driving body to produce a deformation relative to the resonator. The parameter adjustment range of the cavity filter is improved, so that the cavity filter may adapt to more frequency bands, thereby improving the communication quality of the communication device.
