Abstract

A self-contained I.V. set for infusing drugs and secondary medications is disclosed. A mini-I.V. container having a filtered air vent and a valved filling port is filled by a disposable syringe. A drip chamber below the mini-I.V. container receives medication through a drip device at the bottom of the container. From the drip chamber, the medication enters a small bore tube equipped with a roller clamp and an infusion needle fitting. A convenient hanger for the device is provided.

Claims

1. A self-contained solution set comprising a solution container having a filtered air vent and a valved filling port to enable filling the container by means of a syringe without needle, a drip device on the bottom of the container, a drip chamber means on the bottom of the container enclosing the drip device, an infusion tube assembly connected to the bottom of said drip chamber means, a hanger means for the solution set, said hanger means supporting said solution container by an adjacent support member, said support member having a hanger hinged thereto, the support member of the hanger means comprising a support ring at the bottom of the solution container surrounding and encircling the drip chamber means, and said hanger comprising a hanger loop hingedly attached to the support ring by integral flexible hinges and having side portions adapted to straddle side walls of the solution container.

2. A self-contained solution set as defined in claim 1, and the filtered air vent and valved filling port being located on the top of the solution container.

3. A self-contained solution set as defined in claim 1, and the drop chamber means comprising a tubular drip chamber having one end coupled with a sleeve on the bottom of the solution container and its other end coupled with the infusion tube assembly through an adapter thereof.

4. A self-contained solution set as defined in claim 1, and said air vent and valved filling port being located on one side of the solution container near its top.

5. A self-contained solution set as defined in claim 1, and the solution container comprising a small container having a solution capacity of approximately 50 ml.

6. A self-contained solution set as defined in claim 1, and the solution container comprising a molded container including a body portion and a container top for the body portion and being hermetically sealed thereto, and said filtered air vent and valved filling port being located on said container top.

7. A self-contained solution set as defined in claim 6, and a tethered closure cap for the valved filling port on the container top.

8. A self-contained solution set as defined in claim 1, wherein said flexible hinges are attached to said support ring by side ears on said support ring.

9. A self-contained mini-solution set particularly for administering secondary medications comprising a small graduated solution container having a solution capacity of about 50 ml., a filtered air vent and a valved filling port on the solution container near its top, the bottom of the solution container having a solution outlet nipple, a drip device coupled with said nipple, a drip chamber element surrounding the drip device and being coupled to the bottom of the solution container, an infusion tube assembly coupled to the drip chamber element, a hanger means for the mini-solution set for supporting the solution container, said hanger means supporting said solution container by an adjacent support member, said support member having a hanger hinged thereto, said support member of the hanger means comprising a support loop surrounding said solution container, said solution container having an abutment surface near its top and said support loop engaging beneath the abutment surface, a tethered closure cap for said valved filling port on said support loop, and said hinged hanger attached on the support loop by integral flexible living hinge means and adapted to be elevated to a use position above the top of said solution container.

10. A self-contained solution set as defined in claim 9, wherein said flexible living hinge means comprises a pair of opposite side lugs on said support loop, and the hinged hanger has notches formed therein close to said lugs.

11. A self-contained mini-solution set comprising a container including a body portion, a container top hermetically sealed to the body portion and having a skirt projecting outwardly from the side wall of the body portion, a filtered air vent and a valved filling port on the container top, a drip device on the bottom of the container body portion, a drip chamber means on the bottom of the container body portion enclosing the drip device, an infusion tube assembly connected to the bottom of said drip chamber means, a hanger means for the mini-solution set comprising a support loop surrounding the container body portion and engaging supportively beneath said skirt, a tethered closure cap for the valved filling port on the support loop, an arcuate hanger element on said support loop and being hingedly secured thereto by integral hinge means, said support loop, tethered closure cap and arcuate hanger element being integrally formed of compliant material, and said integral hinge means including said hanger element having notches therein adjacent said support loop.
