Title:
MEDICAL INFUSION JOINT HAVING CUT-OFF VALVE
Document Type and Number:
WIPO Patent Application WO/2015/017961
Kind Code:
A1
Abstract:
Disclosed is a medical infusion joint connected to an in vitro indwelling catheter with a cut-off valve (4) for introducing a medium into the body, comprising a joint base (3) and a cut-off valve (4), wherein the joint base (3) and a connecting base (1) are configured as an integral structure or the joint base (3) and a connecting base (1) are configured as two separate structures but are fixedly connected to each other, and the lumen of the joint body (2) is in communication with the lumen of the connecting base (1) via the cut-off valve (4). By installing a cut-off valve (4), the medical infusion joint ensures that the infusion channel is cut off while also eliminating negative pressure, and its structure ensures that the cut-off valve rod (43) must be pushed back before performing another infusion, and after completing the infusion, there is an advancing space for the cut-off valve rod (43) to eliminate negative pressure. The cut-off valve (4) has a use as a flow regulator valve for pushing the cut-off valve rod (43) forwards to gradually cut off. Moreover, the split-configured structure of the joint body (2) and the cut-off valve stem (43) makes it possible to simultaneously and respectively perform infusion and cut-off, and operational interference between the two operations would not happen easily.
