A prepackaged needleless intravenous line assembly is provided as well as a method of delivering intravenous medication and/or fluid to a patient while maintaining sterility of needleless access ports. The pre-packaged needleless intravenous line assembly is a sterile intravenous line with at least one sterile access port, each access port having a disinfection cap installed thereon, sealed within a pouch with at least one strip of multiple sealed disinfection caps. An intravenous tubing kit, having sterile intravenous tubing with capped sterile access ports as well as sealed replacement disinfection caps, is removed from the package and attached to a patient's intravenous catheter. A disinfection cap is removed from the sterile access port. Medication and/or fluid is administered into the access port. A replacement disinfection cap is installed onto the access port.

A medicinal liquid flow control apparatus includes a medicinal liquid flow path that guides a flow of a medicinal liquid. The medicinal liquid flow path includes an inlet flow path through which the medicinal liquid is introduced, a plurality of branch flow paths branching from the inlet flow path, and an outlet flow path to which the plurality of branch flow paths join and through which the medicinal liquid flows out. The medicinal liquid flow control apparatus includes a plurality of transfer tubes configured to correspond to the plurality of branch flow paths, respectively, each of the transfer tubes forming a capillary flow path constituting at least a portion of a corresponding one of the plurality of branch flow paths, and a valve configured to control a flow rate of the medicinal liquid flowing out through the outlet flow path by selectively opening and closing the plurality of branch flow paths.

Methods and devices for accurately pumping small quantities of liquid to a patient with a broad range of flow and low cost.

A method of operating an infusion pump includes transmitting light through or around a drop of fluid suspended from an end of a drip tube for the infusion pump, the end of the drip tube located in a drip chamber for the infusion pump, wherein the drip tube is configured for connection to a source of the fluid; receiving, using an optical system for the pump, light transmitted through or around the drop; transmitting, to a specially programmed microprocessor and using the optical system, data regarding the received light; and, using the microprocessor to calculate a volume of the drop using the data.

An apparatus, system and method for regulating fluid flow are disclosed. The apparatus includes a flow rate sensor and a valve. The flow rate sensor uses images to estimate flow through a drip chamber and then controls the valve based on the estimated flow rate. The valve comprises a rigid housing disposed around the tube in which fluid flow is being controlled. Increasing the pressure in the housing controls the size of the lumen within the tube by deforming the tube, therefore controlling flow through the tube.

An automatic pump-based fluid management system, as described herein, comprises an intercostal pump that is, generally, a resiliently flexible bulb having an inlet and an outlet. The inlet is attached to a first tube that extends from the intercostal pump to a first area of a patient's body, for example, the patient's pleural cavity. The outlet is connected to a second tube that extends from the intercostal pump to a second area of a patient's body, for example, the patient's peritoneal cavity. In use, the intercostal pump is placed between a first rib and a second rib in a patient. The intercostal pump operates by being successively compressed and decompressed between the first and second ribs as the patient breaths.

An interventional ostium occlusion catheter includes a catheter tube with at least one port at a first end, a tip at a second end, and a central lumen, with a positioning component and an occlusion component on the surface of the catheter tube close to the tip. A method of coronary intervention using the catheter includes maneuvering the catheter to an ostium; inserting the catheter into a coronary vessel; activating the positioning component and the occlusion component; and delivering an infusion via the lumen. An interventional system for improving management of ischemic cardiac tissue during acute coronary syndromes includes the catheter; a blood infusion device that delivers controlled reperfusate; and a ventricular unloading device that manipulates myocardial oxygen demand in a coronary chamber. The operator can mitigate reperfusion-related and oxygen-related tissue injury by precisely modulating oxygen re-exposure when re-establishing flow and when using a ventricular unloading device.

A device is disclosed that is configured as a fully autonomous and integrated wearable apparatus for diabetes management. The device comprises a reservoir for storing the medication for subsequent delivery to a patient, a needle for delivering the medication to the patient subcutaneously, a micropump for pumping the medication from the reservoir through the needle for delivering the medication to the patient, control circuitry controlling operations of the micropump, an interposer configured as an adapter for (1) mounting the reservoir, micropump, the control circuitry and the needle, and (2) distributing medication through one or more channels within the interposer from the reservoir to the needle via the micropump and electrical signals between the control circuitry and micropump.

A fluid injection system including a graphical user interface, a fluid control module operatively connected to the graphical user interface, a monitoring control module provided in at least one of the graphical user interface and the fluid control module, a fluid injector operatively connected to the graphical user interface and the fluid control module, at least one fluid path set in fluid communication with the fluid control module, and a hemodynamic monitoring system operatively connected to the fluid path set and the monitoring control module. The hemodynamic monitoring system may be configured to receive electrical signals regarding pressure waves formed in medical fluid directed through the fluid path set based on a location of the fluid path set in a patient's vasculature, to convert the electrical signals to pressure wave form information, and to send the pressure wave form information to the monitoring control module.
