Extraction device for burn and scald film spraying medicine

Abstract

The invention belongs to the technical field of medicine preparation, and particularly discloses an extraction device for a burn and scald film spraying medicine. The device comprises an extraction kettle; a rotating shaft is arranged in the extraction kettle, a plurality of sleeves sleeve the rotating shaft, and diameters of the plurality of sleeves are increased in sequence along an axial direction of the rotating shaft; a containing cavity sleeves each sleeve, the inner wall of each sleeve is provided with an axial track, a first annular track and a second annular track, and the outer wallof each containing cavity is provided with a first clamping block and a second clamping block; the first clamping blocks and the second clamping blocks are separately located at two ends of the sleeves, each first clamping block can slide freely in the corresponding axial track and the corresponding first annular track, and each second clamping block can slide freely in the corresponding axial track and the corresponding second annular track. The device provided by the invention can shorten the extraction time of the extraction kettle and improve extraction efficiency.

Description

technical field [0001] The invention relates to the technical field of medicine preparation, in particular to a burn and scald film spray medicine extraction device. Background technique [0002] Burns refer to tissue damage caused by heat, such as hot liquid, flame, red-hot metal, steam, high-temperature gas, electric energy, chemical substances, radiation, microwaves, etc. Exposure therapy is often used to treat large-area burns, and exposure therapy is often used to treat small-area burns. Scalds are treated with drug application or semi-exposure. Membrane is a new breakthrough in skin injury therapy in recent years. Membrane spray combines the advantages of membrane and spray patch to make a spray, which is sprayed on the skin, mucous membrane affected area and damaged surface to form a layer of soluble biofilm , prolong the residence time of the drug in the affected area, improve the efficacy of the drug, and save other dressings, so as to isolate and kill pathogenic m...

Problems solved by technology

However, due to the size of the extraction tank is usually relatively large, close to the CO 2 Part of the material at the inlet is extracted first, away from CO 2 The extraction is completed after part of the material at the inlet, when close to the CO 2 After the extraction of some substances in the inlet is completed, supercritical CO still needs to be introduced. 2 For away from CO 2 Part of the material at the entrance is extracted, so the extraction time of the entire extraction tank is prolonged, and the extraction efficiency is low
