Kind Code:
A1
Abstract:
A safe medicinal liquid transfer device, comprising a main body (1) and a connecting member lower cover (2), a needle-shaped body (3) provided on the main body (1), and a gas channel (31) and a liquid channel (32) provided in the needle-shaped body (3), separately; an exhaust cavity (11) communicated with the gas channel (31) is provided in the main body (1), and communicated with the atmosphere by means of a breathable water blocking film body (12); a cavity (4) is provided between the main body (1) and the connecting member lower cover (2), and communicated with the liquid channel (32); the connecting member lower cover (2) is provided with a connection portion (21) connected to a syringe; a sealing structure (5) is provided at the connection portion (21); the sealing structure (5) is deformed as pressure is applied to the syringe, allowing for communication between the syringe and the cavity (4). According to the safe medicinal liquid transfer device, a clinical pharmacist can perform medicine dispensing and dosing operations simply and safely. The exhaust design comprising the exhaust cavity (11) and the breathable water blocking film body (12) allows for efficient balance of the air pressure inside and outside a container. The further inclusion of a sealing structure (5) allows for a closed design, effectively preventing the medicinal liquid from spraying out. The invention thus prevents the waste of medicines, and protects the safety of the pharmacist.
