Abstract

A flow control apparatus includes a body, a door, a drip chamber holster, and a valve. The door is pivotally coupled to the body. The drip chamber holster is coupled to one of the body or the door to retain a drip chamber. The valve is disposed within the body and is configured to receive a fluid line coupled to the drip chamber when the door is in an open position. The valve is operatively coupled to the door to secure the fluid line within the valve when the door is in a closed position.

First claim

What is claimed is:

1. A flow control apparatus, comprising:
a body;
a door pivotally coupled to the body;
a drip chamber holster coupled to at least one of the body and the door, the drip chamber holster configured to retain a drip chamber; and
a valve disposed within the body and configured to receive a fluid line coupled to the drip chamber when the door is in an open position, the valve comprising:
a first casing clamshell;
a second casing clamshell;
a filler disposed within the first and second casing clamshells; and
a plunger configured to engage the filler within the first and second casing clamshells through a hole of one of the first and second casing clamshells to thereby operatively deform the fluid line within the first and second valve casing clamshells when engaging the filler;
wherein the valve is operatively coupled to the door to secure the fluid line within the valve when the door is in a closed position.

2. The flow control apparatus according to claim 1 , wherein the first casing clamshell is configured to latch onto the second casing clamshell.

3. The flow control apparatus according to claim 2 , further comprising a closing arm pivotally coupled to the door and coupled to the first casing clamshell, wherein the closing arm closes the first casing clamshell when the door is moved to the closed position.

4. The flow control device according to claim 3 , wherein the closing arm is further configured to latch the first casing clamshell when the door is moved to the closed position.

5. The flow control device according to claim 3 , further comprising a latch component coupled to the closing arm to thereby allow the first casing clamshell to latch onto the second casing clamshell.

6. The flow control apparatus according to claim 5 , wherein the latch component is a female latch component.

7. The flow control apparatus according to claim 3 , wherein the closing arm is coupled to the first casing clamshell via a latch component.

8. The flow control apparatus according to claim 1 , further comprising an image sensor, wherein the drip chamber holster is configured to position the drip chamber within a field of view of the image sensor.

9. The flow control apparatus according to claim 1 , wherein the valve includes first and second casing clamshell, wherein the flow control apparatus further comprises:
a closing arm pivotally coupled to the door;
a first latch component coupled to the closing arm and to the first casing clamshell; and
a second latch component coupled to the second casing clamshell.

10. The flow control apparatus according to claim 9 , wherein when the door is opened, the closing arm is configured to pull on the first latch component thereby causing the first latch component to rotate up and away from the valve to thereby release pressure placed on the valve from the first latch component.

11. The flow control apparatus according to claim 10 , wherein the flow control apparatus is configured such that once the first latch component disengages from the second latch component, the closing arm pulls open the casing clamshells as the first latch component is pulled away from the valve.

12. The flow control apparatus according to claim 1 , further comprising a safety valve configured to receive the fluid line.

13. A flow control apparatus, comprising:
a body;
a door operatively coupled to the body;
a drip chamber holster disposed in spaced relation to the body, the drip chamber holster configured to retain a drip chamber;
a valve disposed within the body and configured to control fluid flow through a fluid line coupled to the drip chamber, the valve having first and second casing clamshells, the valve comprising:
a filler disposed within the first and second casing clamshells; and
a plunger configured to engage the filler within the first and second casing clamshells through a hole of one of the first and second casing clamshells to thereby operatively deform the fluid line within the first and second casing clamshells when engaging the filler; and
a closing arm operatively coupled to the door;
a first latch component coupled to the closing arm and to the first casing clamshell; and
a second latch component coupled to the second casing clamshell.

14. The flow control apparatus according to claim 1 or 13 , wherein the filler has at least two differing stiffness layers.

15. The flow control apparatus according to claim 13 , wherein the closing arm closes the first casing clamshell when the door is moved to a closed position.

16. The flow control apparatus according to claim 15 , wherein the closing arm is further configured to latch the first casing clamshell when the door is moved to the closed position.

17. The flow control device according to claim 13 , further comprising a latch component coupled to the closing arm to thereby allow the first casing clamshell to latch onto the second casing clamshell.

18. The flow control apparatus according to claim 13 , further comprising an image sensor, wherein the drip chamber holster is configured to position the drip chamber within a field of view of the image sensor.

19. The flow control apparatus according to claim 13 , wherein when the door is opened, the closing arm is configured to pull on the first latch component thereby causing the first latch component to rotate up and away from the valve to thereby release pressure placed on the valve from the first latch component.

20. The flow control apparatus according to claim 13 , wherein the flow control apparatus is configured such that once the first latch component disengages from the second latch component, the closing arm pulls open the casing clamshells as the first latch component is pulled away from the valve.
