Hydrophilic infusion tubes and infusion components are provided. A fluid pathway connects a first fluid port and a second fluid port, the fluid pathway formed of a base material suitable for fluid infusion and a hydrophilic fluid interfacing surface disposed on an inner surface of the fluid pathway. The hydrophilic fluid interfacing surface provides a water wetting contact angle that is less than a water wetting contact angle provided by the base material. Infusion sets are also provided.

The present invention relates to an intravenous infusion set providing delivery of intravenous fluid to patients. An intravenous infusion set (10) to administer continuous air free delivery of intravenous fluid to a patient, said intravenous infusion set (10) comprising: a drip chamber (12), a flexible infusion line (22) of sufficient length connecting a lower end (20) of the drip chamber (12) to a standard connector (24) at the patient end so that a needle or a catheter could be connected to the patient; a roller clamp (26) arranged between the drip chamber (12) and the standard connector (24) being movable along the length of the flexible infusion line (22), said drip chamber (12) provided with a spike (14) on the upper end (16) and a flow regulating and stopping member (18) at its lower end (20) configured to administer continuous air free delivery of intravenous fluid to patients.

Transfer devices with vial adapter and/or an infusion set for reducing overdosing/underdosing of an infusion bag are provided. The transfer device provides user- controlled fluid transferring between an infusion liquid container and a drug-containing container. In one aspect, the transfer device provides user-controlled venting that can be used during liquid transfer between the infusion liquid container and a drug-containing container.

An administrable liquid medicine preparation tool is provided with a first port to which a syringe is attachable, a second port to which a syringe is attachable, a main body provided with a liquid flow path that communicates the first port with the second port, a hydrophilic filtration membrane that divides the liquid flow path into a first port side flow path and a second port side flow path, a first air discharge hole that communicates the first port side flow path with the outside, a first air-permeable membrane that blocks the first air discharge hole in an air-permeable manner, a second air discharge hole that communicates the second port side flow path with the outside, and a second air-permeable membrane that blocks the second air discharge hole in an air-permeable manner.
