CHAIN COMPOSITION PREPARATION APPARATUS AND PREPARATION METHOD

WIPO Patent Application WO/2023/066353

A1

Disclosed is a chain composition preparation apparatus, comprising a perfusion part, an injection part, a first connecting tube, a second connecting tube, a distribution valve and an infusion tube. The perfusion part is in communication with the injection part via the first connecting tube, the distribution valve is in communication with the first connecting tube via the second connecting tube, and the infusion tube is connected to the distribution valve; the distribution valve is also used to connect to an external gas supply part and a liquid supply part. The perfusion part is used to suck gas in the gas supply part and liquid in the liquid supply part to sequentially enter the second connecting tube, so as to form a drug in an alternating gas-liquid dosage form. The injection part is used to push the drug in the alternating gas-liquid dosage form to pass through the distribution valve and enter the infusion tube. Thus, using the present chain composition preparation apparatus, integration of drug configuration and drug injection can be achieved, so that convenience of drug injection is improved, and drug injection efficiency is improved.
