A channel for a medicinal liquid is formed in a filter-integrated medicine transfer device according to an embodiment of the present disclosure. The filter-integrated medicine transfer device includes: a housing having an air passage that diverges from a medicinal liquid channel and is connected to outside; at least one hydrophobic air-passing filter disposed in the housing and disposed at a boundary between the air passage and the medicinal liquid channel; and at least one medicine transfer pipe disposed in the housing and having a capillary channel constituting a portion of the medicinal liquid channel.

The present invention discloses an anti-bubble infusion drip chamber. The anti-bubble infusion drip chamber comprises a drip chamber main body; the drip chamber main body has an upper portion and a lower portion, namely a drip chamber portion arranged on the upper portion and a filtering portion arranged on the lower portion; the filtering portion is provided with a liquid storage cavity communicated with an inner cavity of the drip chamber portion, and a liquid medicine filter and an air filter which are arranged on two sides of the liquid storage cavity; a liquid medicine flow channel is arranged on the side wall of the filter and is provided with a liquid inlet and a liquid outlet; the liquid inlet is formed above the liquid outlet; a liquid medicine filter membrane is arranged between the liquid inlet of the flow channel and the liquid storage cavity; and an air filter is arranged on the drip chamber main body on at least one side of the filter membrane. A horizontally-placed liquid medicine filter membrane in the traditional drip chamber can cause unsmooth flow of liquid medicine due to surface tension of the liquid medicine and accumulation of impurities. By making an improvement on the drip chamber, the liquid medicine filter membrane is vertically or obliquely arranged, so that on one hand, the impurities can be prevented from being accumulated on the surface of the filter membrane, and on the other hand, the surface tension of the liquid medicine can be destroyed.

Modular intravenous (IV) assemblies are provided. The modular IV assembly includes a drip chamber having a body and an inlet connector, a base housing coupled directly to a base portion of the drip chamber, the base housing having an inlet port in fluid connection with the drip chamber and a flow path cavity in fluid connection with the inlet port and a flow control assembly coupled directly to a first portion of the base housing. Any of a filter assembly, an anti-run dry member, a check valve and an air vent assembly may be included in the modular IV assembly. IV sets and methods of use are also provided.

Methods and systems for infusing a user. An infusion pump includes a housing with an elastic component configured to expand and store potential energy. The infusion pump includes a first tube fluidically coupled to an outlet of the housing. The first tube is configured to conduct the fluid from the housing at a first flow rate. The infusion pump includes an air filter fluidically coupled to a distal end of the first tube via an air filter inlet. The infusion pump includes a second tube fluidically coupled to the air filter via an air filter outlet. The second tube is configured to adjust the first flow rate of the fluid conducted from the housing to a second flow rate. The infusion pump further includes one or more components for distributing the fluid to a user, the one or more components fluidically coupled to an outlet of the second tube.

Flow controllers for intravenous (IV) tubing are provided. A flow controller may include first and second structural members defining a cavity therebetween for a portion of the tubing, wherein the first structural member is linearly slidable along a length of the tubing to compress at least part of the portion of the tubing to control flow of a medical fluid through the tubing. A flow controller may include a first ramped wedge structure, a second ramped wedge structure configured to slide over the first ramped wedge structure to compress a portion of the IV tubing disposed between the first ramped wedge structure and the second ramped wedge structure, a yoke having a linear slot, a wheel having a pin that is radially separated form a center of the wheel and is slidably disposed in the linear slot, and a transfer structure coupled to the yoke and the first ramped wedge structure. IV sets that include a flow controller are also provided.
