Reconstitution vial mixing apparatus
View Patent ↗A medicinal vial reconstitution and IV dispensing device includes a bifurcated receptacle adapted to engage a medicinal vial, and a valve or barrier for selectively opening and closing the medicinal vial from fluidic communication with the patient IV line. The reconstitution device mixes medication with saline solution from an IV bag through a dedicated channel. The reconstitution device receives a medication vial containing the powdered medication. The reconstituted medication is then passed back into the IV bag for uniform mixing. A flow control element ensures fluid flow only from the vial to the bag. Once mixed, the reconstituted medication achieves a desired concentration in the IV bag. The (now medicated) saline solution in the IV bag is dispensed back through the reconstitution device via an IV line to the patient, and the flow control element redirects fluid only to the IV line and prevents any backflow with the vial.
1. An intravenous (IV) inline medication dispensing device, comprising:
an IV connector having a bag spike adapted for inline connection between a fluid reservoir and an IV port adapted for receiving an IV line to a patient via a controlled flow path;
a vial receptacle fluidically coupled to a transfer channel for medicinal transport;
the transfer channel forming a continuous bifurcated junction body and IV connector extending from the bag spike to the IV port, thereby defining the controlled flow path;
a partition in the bag spike defining a fluidic separation between the transfer channel and the controlled flow path; and
a tapered end on the bag spike adapted for engaging the fluid reservoir to establish fluidic communication between the fluid reservoir and each of the controlled flow path and the transfer channel, the bag spike having first and second orifices, at least one of the first and second orifices located on a side of the tapered end, the first and second orifices defining respective fluidic connections from an engaged fluid reservoir to the controlled flow path and the transfer channel.
2. The device of claim 1 wherein the IV connector and bifurcated junction body form a unitary structure.
3. The device of claim 1 wherein the fluid reservoir is an IV bag and the tapered end is adapted for engaging a predefined port on the IV bag.
4. The device of claim 1 wherein the partition imposes a fluidic barrier between the transfer channel and the controlled flow path.
5. The device of claim 1 wherein the IV connector includes parallel channels corresponding to the transfer channel and controlled flow path, the partition defining a fluidic separation between the parallel channels.
6. The device of claim 1 wherein the first and second orifices are disposed at different distances from a tip of the tapered end.
7. The device of claim 1 wherein the vial receptacle incudes a fluidic closure forming a fluidically sealed system between the vial receptacle and the IV port.
8. The device of claim 7 wherein the fluidic closure is adapted for selective fluidic engagement with a medicinal source, the selective fluidic engagement allowing fluidic communication of the medicinal source with the fluid reservoir.
9. The device of claim 1 wherein the vial receptacle includes a flange, the flange configured for deformative engagement with a medicinal vessel containing the medicinal source.
10. The device of claim 9 further comprising a needle disposed within the flange, the needle having an orifice and adapted for sealable engagement with a resilient closure on the medicinal vessel.
11. The device of claim 1 further comprising a plurality of planar ribs, the bifurcated junction body and the IV connector intersecting the plurality of ribs, the ribs extending in a plane perpendicular to an axis of the controlled flow path through the IV connector.
12. The device of claim 11 wherein the plurality of planar ribs are disposed at a junction of the IV connector and the transfer channel, the junction formed more than half the length of the IV connector distal from a tip of the tapered end.
13. The device of claim 1 wherein the controlled flow path defines a continuous, uninterrupted fluid coupling through the bifurcated connector body from the bag spike to the IV port; and the transfer channel defines a continuous, uninterrupted fluid coupling through the bifurcated connector body from the vial receptacle to the bag spike.
