## Abstract

An intravenous (“IV”) drip chamber for reducing turbulence is disclosed, along with related systems and methods. The IV drip chamber includes an enclosure having an entrance and an exit. A ramp, such as with an at least substantially continuous incline, extends from a first location proximate the entrance, such as below the entrance, to a second location proximate the exit, such as above the exit. In this way, droplets of medication or other fluid may travel smoothly and/or with a smaller fall through the drip chamber, thereby reducing formation of micro-bubbles or other turbulence.

## Claims

### Claim 1

An intravenous (“IV”) drip chamber for reducing turbulence, said IV drip chamber comprising:
an enclosure having an entrance at an upper portion of the enclosure and an exit at a lower portion of the enclosure; and
a ramp extending from a first location adjacent to the entrance to a second location adjacent to the exit.

### Claim 2 (depends on 1)

The IV drip chamber of claim 1 wherein:
the entrance is located at, or extends to, an upper surface of the enclosure;
the exit is located at, or extends to, a lower surface of the enclosure;
the first location for the ramp is below the entrance; and
the second location for the ramp is above the exit.

### Claim 3 (depends on 2)

The IV drip chamber of claim 2 wherein:
the ramp comprises at an at least substantially continuous incline.

### Claim 4 (depends on 3)

The IV drip chamber of claim 3 wherein:
the ramp is attached to one or both of a sidewall and the upper surface of the enclosure at a first end thereof.

### Claim 5 (depends on 4)

The IV drip chamber of claim 4 wherein:
the ramp has an at least substantially linear longitudinal axis.

### Claim 6 (depends on 5)

The IV drip chamber of claim 5 wherein:
the ramp has an at least substantially constant slope.

### Claim 7 (depends on 6)

The IV drip chamber of claim 6 wherein:
the ramp is free at a second end thereof.

### Claim 8 (depends on 6)

The IV drip chamber of claim 6 wherein:
the ramp is attached to the sidewall of the enclosure at a second end thereof;
an aperture is provided at the second end of the ramp.

### Claim 9 (depends on 8)

The IV drip chamber of claim 8 further comprising:
a mesh provided at the aperture.

### Claim 10 (depends on 6)

The IV drip chamber of claim 6 wherein:
at least a majority of an upper surface of the ramp is at least substantially flat.

### Claim 11 (depends on 6)

The IV drip chamber of claim 6 wherein:
at least a majority of an upper surface of the ramp has a cupped shape.

### Claim 12 (depends on 6)

The IV drip chamber of claim 6 further comprising:
a mesh provided below the ramp and spanning at least substantially all of a lateral cross section of the enclosure.

### Claim 13 (depends on 3)

The IV drip chamber of claim 3 wherein:
the ramp forms a helical shape.

### Claim 14 (depends on 13)

The IV drip chamber of claim 13 further comprising:
a support shaft extending between the upper surface of the enclosure and the lower surface of the enclosure, wherein the ramp extends at least partially about the support shaft to form the helical shape.

### Claim 15 (depends on 14)

The IV drip chamber of claim 14 further comprising:
a first aperture located in the lower surface of the enclosure which accommodates a first end of the support shaft; and
a second aperture located in in the upper surface of the enclosure which accommodates a second end of the support shaft.

### Claim 16 (depends on 13)

The IV drip chamber of claim 13 wherein:
the ramp is attached to a sidewall of the enclosure.

### Claim 17 (depends on 2)

The IV drip chamber of claim 2 wherein:
the ramp comprises multiple surfaces which are spaced apart from one another.

### Claim 18

A system for intravenous (“IV”) delivery of medication, said system comprising:
an IV drip chamber comprising:
an enclosure having an entrance located at an upper surface of the enclosure and an exit located at a lower surface of the enclosure; and
a ramp having an upper surface forming an at least substantially continuously incline at an at least substantially constant slope extending from a first location below the entrance to a second location above the exit.

### Claim 19 (depends on 18)

The system of claim 18 further comprising:
a container for medication fluidly connected to said entrance;
IV tubing fluidly connected to said exit; and
an IV pump located along the IV tubing.

### Claim 20

A method for intravenous (“IV”) delivery of medication, said method comprising:
providing an IV drip chamber comprising:
an enclosure having an entrance located at an upper surface of the enclosure and an exit located at a lower surface of the enclosure; and
a ramp comprising an at least substantially continuous incline at an at least substantially constant slope extending from a first location below the entrance to a second location above the exit;
fluidly connecting an IV catheter or port to a patient's vascular system;
fluidly connecting a container with medication to said entrance to said enclosure of said IV drip chamber;
fluidly connecting IV tubing to said exit to said enclosure of said IV drip chamber;
fluidly connecting said IV tubing to said IV catheter or port;
connecting an IV pump to said tubing; and
operating said IV pump to cause flow of medication from said container into the patient's vascular system.
