Description

technical field [0001] The invention relates to a medical instrument for quick dispensing, in particular to a disposable medicine dispensing catheter which is more convenient for nurses to use when dispensing medicine with a medical infusion rapid dispensing device. Background technique [0002] At present, a disposable drug dispensing catheter used by the rapid medical infusion dispenser, when the nursing staff uses it to dispense drugs, especially when the drug to be dissolved and inhaled is powder, since the powder drug bottle is in a sealed environment, it is difficult to inject the solvent and inhale the drug. The larger positive and negative pressures in the bottle seriously hinder the rapid work of the dispenser, and also cause more drug residues. Contents of the invention [0003] The purpose of the present invention is to provide a medical rapid dispensing device capable of filtering the air entering the medicine bottle, ensuring that the medicine is not polluted,...
