APPARATUS FOR LIQUID TRANSFER INTO BOTTLE OF THERAPEUTICAL LIQUID
Document Type and Number:
Japanese Patent JPH02297372
Kind Code:
A
Abstract:
PURPOSE: To maintain always ventilation to prevent any liquid form leaking out through an air duct by using a hydrophobic filter to close the opening of air duct inside a bottle. CONSTITUTION: This device for sending a medical liquid has an air duct 9 opened in a short socket 10 inside a flange 4, in order to ventilate inside a bottle, whenever the liquid flows out of the bottle. A rising tube 11 is fitted to inside this socket, whose top end is closed with a hydrophobic filter 12 to be fitted onto the rising tube 11. This filter 12 consists of a filter housing having a filter element 13, whose penetrating direction is the same axial as the axial line of the rising tube. This makes it any longer impossible to allow any liquid to enter into the air duct 9, even if it is removed to be attached to any other bottle for so many times.
