Preparation method of atomized liquid for preoperative intervention

Abstract

The invention discloses a preparation method of atomized liquid for preoperative intervention and aims to solve the problem of broncholithiasis treatment. The preparation method comprises the following steps: extracting volatile oil for standby use from leaves of Cunninghamia lanceolata (Lamb.) Hook., leaves of cannabis sativa L., Rabdosia sculponeata (Vaniot) Hara and Bulbophyllum inconspicuum Maxim. by steam distillation, and reserving residues; mixing adult Gryllotalpa africana Palisot et Beaurois (or adult G. unispina Saussure), root of small-leaf oriental grape, root of Rubus wilsonii Duthie, seeds of Carex baccans Nees, larval Holotrichia diomphalia Bates (or larval Anomala carpulenta Motsch.), Buchnera cruciatas Hamilt., root of Salix wallichiana Anders., seeds of Euryale ferox Salisb. and the residues obtained in step 1, and performing aqueous extraction to obtain an extract; concentrating the extract under reduced pressure, adding ethyl alcohol into the concentrated extract, keeping the concentrated extract standing under refrigeration, taking and filtering supernatant, recycling ethyl alcohol from filtrate, adding 0.5w% of powdered activated carbon into concentrated filtrate, boiling the concentrated filtrate for 30 minutes after uniform stirring, cooling the concentrated filtrate to 50DEG C, and performing suction filtration with a 0.4mu m filter membrane; and adding 0.2w% of potassium sorbate into suction filtrate, mixing the potassium sorbate and the suction filtrate uniformly, and spraying the volatile oil obtained in step 1 into the mixture of the potassium sorbate and the suction filtrate, uniformly mixing the volatile oil and the mixture, and performing subpackaging. Clinical experiments prove that the atomized liquid has the characteristics of good curative effect and high safety in broncholithiasis treatment and is worth application and popularization.

Description

Technical field [0001] The invention relates to the field of traditional Chinese medicine, in particular to a method for preparing a preoperative intervention atomization liquid for stone removal under a bronchoscope. Background technique [0002] Bronchial calculi are calcified masses located in the lumen of the bronchus or eroded into the lumen, which can cause severe bronchial irritation and obstruction. Previous studies have suggested that most of the reasons for the formation of stones are: foreign bodies attracted or infected secretions constitute the core of the stones, and the stones are gradually formed by the deposition of calcium and phosphorus. Different from hepatobiliary stones and urethral stones, bronchial stones are attached to the bronchial wall and are difficult to move. Therefore, the effect of "diuresis and stone removal" in the current conservative treatment is not ideal. The results of pathological studies in recent years have shown that during the formati...

Problems solved by technology

Some patients can remove stones through bronchoscope, but due to the aggregation and adhesion of stones, accidents may occur during the removal process if the stones are violently pulled or pulled. Therefore, 68-81% of patients fail to remove stones, and thoracotomy is performed. huge
