Systems and methods of micro-infusion of medical fluids are disclosed. Micro-infusion systems may include a pump, a patient interface, tubing between the pump and the interface, and a micro-infusion device along the tubing. A first portion of the tubing above the micro-infusion device is longer than a second portion of the tubing below the device. The micro-infusion device may include a chamber in-line with the tubing, a first valve between the chamber and the first portion of the tubing, a second valve between the chamber and the second portion of the tubing and a third valve between the chamber and a dump chamber. The second valve may be slidably disposed within the chamber. A medical fluid may be provided into the chamber that slides the second valve displacing another fluid in the chamber through the third valve into the dump chamber.

A syringe with passive needle protection for administering a medicament dose to a patient, comprising a hollow body forming the syringe housing and containing the medicament active substance, at the distal end of which a hollow needle provided for injection of the active substance is mounted in a bearing sleeve, and in which a displaceable plunger provided at the end with a receiving hole for the hollow needle is arranged, for the most complete possible delivery of medicament while avoiding undelivered medicament residues. For this purpose, the piston is designed in several parts; in addition to a needle holder having a retaining clip for the hollow needle, it comprises a piston jacket which is shaped such that, when the needle holder is inserted, it leaves free inflow channels into the enclosed end of the hollow needle for the active substance on both sides of the retaining clip.

Mixing/administration systems and methods for preparing an agent for administration to an individual are disclosed. Caps may be included as part of the system, which may include compositions comprising at least one of a cleansing, antiseptic, antimicrobial, or disinfectant agent. The caps may additionally be included that may be used for hemostasis at an injection site. Packaging and/or the mixing/administration system within it may include a tracking mechanism for data tracking regarding many different aspects of the system, including aspects of manufacture and administration.

A gas mixture apparatus includes a measurement control system, an activation system, a pressurized chamber with one or more gases, and a mixing chamber. A filter can be preattached to an outlet of the mixture apparatus, allowing excess gas to be discharged therethrough and then atmospheric air to be drawn into the mixture apparatus through the filter for creating a therapeutic gas mixture.

A pre-filled medical delivery assembly can have a blow-fill-seal (BFS) module, a manifold, and a casing. The BFS module can have a pair of reservoirs, and a pair of sealed ports. Each reservoir can have a respective liquid agent therein. Each port can be in fluid communication with a respective one of the reservoirs. Part of the BFS module can be inserted into the manifold, and the casing can protect part of the BFS module exposed from the manifold. An orientation of the casing can be reversed, and the casing can be used to push the BFS module into the manifold to breach the seals and/or to compress the reservoirs to dispense the liquid agents. The disclosed assemblies can combine the liquid agents from the BFS module and deliver the combination as a single dose of a therapeutic agent (e.g., vaccine, drug, medicament, etc.) to a patient.

A device for injecting a reconstitutable liquid mixture is provided. The device has a first containment chamber and a second containment chamber for a first component and a second component of the reconstitutable liquid mixture, respectively, first mechanical and fluidic connection elements between the first and second containment chambers, and second mechanical and fluidic connection elements between the second containment chamber and an injection needle. The first containment chamber has a first upper surface and a first lower surface in the shape of a cone or truncated cone having a common base and opposite extensions forming a non-zero angle β therebetween. The second containment chamber has a second upper surface and a second lower surface in the shape of a cone or truncated cone and having a common base and opposite extensions forming a non-zero angle α therebetween. The first and the second lower surfaces are deformable by compression.

A pre-filled medical delivery assembly can have first and second blow-fill-seal (BFS) modules and first and second connectors. Each BFS module can have a reservoir with a fluid agent and a neck with a seal. Each connector can have a respective recess with a piercing element. The first connector can have an outlet port, and the second connector can have an inlet/outlet (I/O) port. The connectors can be coupled together via the outlet and I/O ports. The neck of each BFS module can be inserted into the recess of the respective connector such that the piercing element breaches the seal, thereby providing a fluid path between the reservoirs. The disclosed assemblies can allow the combination of separate fluid agents via the coupled connectors and subsequently delivery of the combination as a single dose of a therapeutic agent to a patient by replacing the first connector with an administration hub.

Various implementations include a mixing vial system. The system includes a hypodermic syringe and a mixing vial. The mixing vial includes a vessel, a stopper, and a dislodgeable plug. The vessel includes an open end, a closed end, and a side wall. A hollow interior chamber is defined by the side wall and the closed end. The open end defines a neck. The stopper includes an open proximal end, a closed distal end, and a stopper side wall. The closed distal end and the stopper side wall define a hollow interior chamber. The stopper is positioned in a sealing relationship within the neck. The dislodgeable plug is positioned in and sealing the open proximal end of the stopper. The closed distal end of the stopper is penetrable by a needle of the hypodermic syringe to dislodge the dislodgeable plug to effect mixing of contents of the stopper and the vessel.

An injection system includes a syringe body defining a proximal opening at a proximal end thereof and a distal needle interface at a distal end thereof. The system also includes proximal and distal stopper members disposed in the syringe body, forming respective proximal and distal drug chambers. The system further includes a plunger member configured to be manually manipulated to insert the proximal stopper member relative to the syringe body. Moreover, the system includes a fluid conveying assembly including a penetrating member configured to penetrate the distal stopper member to fluidly couple the proximal and distal drug chambers, a distal exit tube, and a transfer member disposed at least partially around a portion of the penetrating member and defining a fluid passage. A distal end of the penetrating member is disposed in the distal exit tube.

A syringe-based device includes a housing and an actuator mechanism including a first member and a second member. The first member includes a syringe body and a plunger, the plunger being movably disposed within the syringe body. The second member includes a second member plunger seal and a valve operably and selectively coupled to the second member plunger seal such that the valve is positioned proximal of the second member plunger seal. The device also includes a first fluid reservoir and a second fluid reservoir. The device transitions from a first configuration to a second configuration in which the first type of fluid is expelled from the first fluid reservoir, to a third configuration in which the second type of fluid is expelled from the second fluid reservoir through the valve.
