Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a multi-station medicine dispensing device and a medicine liquid transfer device used therefor. Background Art

[0002] At present, there are two main modes of drug preparation for intravenous infusion in hospitals. One is centralized preparation at the Pharmacy Intravenous Admixture Services (PIVAS), and the other is temporary preparation in the emergency room or ward. Most of the two preparation modes are manually operated by medical staff, which has problems such as low efficiency, slow speed, and high labor intensity. At the same time, during the preparation process, it is easy to cause leakage and particle contamination due to multiple punctures of the rubber stopper of the saline bottle, especially when preparing cytotoxic drugs, chemotherapy drugs, allergenic drugs, highly active drugs, etc., which are prone to drug splashing and volatilization, thereby causing drug damage to the dispensing personnel, and even irreversible consequences.

[0003] In order to overcome this problem, some automatic dispensing devices have appeared on the market, but the existing automatic dispensing devices still have certain defects: 1. The existing automatic dispensing devices are large in size and often take up a large space. They cannot be placed in a biological safety cabinet and there is still a certain risk of drug volatilization and spillage; 2. The existing automatic dispensing devices often need to rotate the entire workbench to achieve the relative position exchange between the saline bottle and the bottle of medicine to be prepared. Therefore, the operating speed of the existing automatic dispensing devices is often limited, resulting in reduced dispensing efficiency and increased load. The equipment needs to be equipped with a high-power drive motor, which increases the energy consumption of the equipment and further increases the production cost of medicine solution preparation.
