Described herein are devices for delivering at least two different medications without requiring disconnections and reconnections of medication syringes. In some embodiments, the devices can accommodate at least two syringes simultaneously. In some embodiments, the device can be torqued while delivering the at least two different medications without loosening the outlet port from an intravenous line the device is hooked up to.

A flow control device includes a housing having a primary inlet, a secondary inlet, and an outlet disposed downstream of the primary and secondary inlets. The flow control device further includes a chamber defined by an inner circumferential surface of the housing. The chamber fluidly connects the primary and secondary inlets with the outlet. A valve member is mounted in the chamber to pivot toward and block the primary inlet by fluid pressure in the secondary inlet when fluid pressure into the secondary inlet is higher than fluid pressure into the primary inlet.

A wearable drug delivery device that can deliver a liquid drug stored in a container to a patient or user is provided. A soft needle or cannula can be placed in fluid communication with the liquid drug and can be coupled to a needle insertion component that provides access to the patient. A drive system of the drug delivery device can expel the liquid drug from the container to the patient through the soft needle or cannula. The wearable drug delivery device can include components for preventing backflow and eliminating air within the liquid drug. As a result, the comfort of the patient can be enhanced and correct drug dosages can be provided when using the drug delivery device.

A neurosurgical apparatus includes a guide device and a neurosurgical instrument is disclosed. The guide device includes a tube for insertion into the brain and a head attached to the proximal end of the tube for affixing the guide device to a hole formed in the skull. The head has a passageway therethrough in communication with the bore of the tube such that the bore of the tube and the passageway through the head define an internal channel through which a neurosurgical instrument can be passed into the brain of the subject. The neurosurgical instrument is for insertion to a desired brain target through the internal channel of the guide device. The apparatus includes one or more sealing elements for providing a fluid tight seal between the internal channel of the guide device and the exterior of the neurosurgical instrument to prevent fluid leakage from guide tube.

A configurable fluid delivery system and methods for its use are disclosed. The system may include one or more control units, fluid delivery units, fluid actuator units, and disposable units. Data sources and sensors on each of the delivery units, actuator units, and disposable units may provide data to the control unit, thereby identifying the components along with the manner in which they may be configured. The control unit may notify a user regarding the status of any one or more of the delivery, actuator, and disposable units to indicate their appropriateness for delivering a fluid according to one or more selected procedures and protocols. Also disclosed are methods by which the configurable fluid delivery system may provide data to a user to assist the user in assembling and testing a particular configuration of the fluid delivery system for a specific use.

Flush syringe assemblies are described herein. Such flush syringe assembly may include a collapsible syringe barrel including a corrugated side wall defining a chamber, a closed proximal end, a distal end having a distal wall with an elongate tip extending distally therefrom having a passageway therethrough in fluid communication with said chamber, a pre-selected amount of sterile fluid in the chamber, and a locking element. A collar may be disposed on the distal wall of the barrel and surrounding the elongate tip. An absorbent material and disinfectant or antimicrobial agent may be disposed in a compartment of the collar.

A fluid injector system includes a control device operatively associated with each of two or more drive components configured to pressurize and inject a first fluid from a first fluid reservoir through a fluid conduit, and at least a second fluid from a second fluid reservoir through the fluid conduit. The fluid conduit is in selective fluid communication with the first and second fluid reservoirs. The control device has at least one processor programmed or configured to actuate a second drive component to pressurize and inject the second fluid through the fluid conduit, and while the second drive component is actuated, actuate a first drive component to introduce intermittent pulses of the first fluid to create a flow front interface between the first fluid and the second fluid in the fluid conduit to prevent backflow of the second fluid through the fluid conduit into the first fluid reservoir.

An apparatus for preventing backflow. The apparatus includes a housing; a trap flow part forming a flow passage for a medical fluid, a discharge part provided on an lower portion of the housing and to receive the medical fluid from the trap flow part and to discharge the medical fluid; a backflow prevention chamber part provided between the trap flow part and the discharge part; and a plate-shaped backflow prevention member provided on one surface of the inner side of the backflow prevention chamber part connected to the trap flow part and in close contact with a periphery of the outlet opening, the plate-shaped backflow prevention member being provided to open or close the opening depending on forward flow and the backflow of the medical fluid.

An apparatus for preventing backflow includes a body forming an accommodating portion which forms a transport passage of a fluid inward, wherein the accommodating portion comprises a double backflow prevention chamber to prevent backflow of the fluid, and a double backflow prevention member provided in the accommodating portion and stepwise implementing opening and closing of the double backflow prevention chamber, In particular, the accommodating portion includes an inflow chamber provided at an upper portion of the body and into which the fluid flows; a discharge chamber through which the fluid is discharged to a lower portion of the inflow chamber; and the double backflow prevention chambers respectively provided at the lower portion of the inflow chamber and the upper portion of the discharge chamber.
