Abstract

The present invention relates to an infusion control device designed to secure the infusion control device to a drip chamber attached to an infusion tube. The infusion control device comprises a light indicator and a microprocessor. The microprocessor determines the amount of fluid in an infusion bottle providing fluid to the transparent drip chamber, and provides instructions to the light indicator to illuminate the infusion bottle when the amount of fluid in the infusion bottle is less than a predetermined first limit.

Claims

1. An infusion control device, comprising:

a securing unit configured to secure said infusion control device to a transparent drip chamber attached to an infusion tube,

a light indicator arranged on a top side of said infusion control device and configured to illuminate an infusion bottle providing fluid to the transparent drip chamber, and

a microprocessor configured to;

determine the amount of fluid in said infusion bottle providing fluid to the transparent drip chamber, and

provide instructions to said light indicator to illuminate said infusion bottle when said amount of fluid in said infusion bottle is less than a predetermined first limit.

2. The infusion control device according to claim 1, further comprising an input unit configured to receive information of a desired flow of fluid through said infusion tube,

wherein said microprocessor is further configured to:

control a flow of fluid through said infusion tube in response to the desired flow of fluid, and

provide instructions to said light indicator to illuminate said infusion bottle when said flow of fluid deviates from said desired flow of fluid more than a predetermined second limit.

3. The infusion control device according to claim 2, further comprising a drop counter to determine said flow of fluid by detecting a speed of dropping fluid in said transparent drip chamber.

4. The infusion control device according to claim 2, wherein said drop counter is an optic sensor.

5. The infusion control device according to claim 2, further comprising a flow controller, wherein said microprocessor is configured to provide instructions to said flow controller to control said flow of fluid through said infusion tube.

6. The infusion control device according to claim 5, wherein said flow controller is a motor controlled cam disk.

7. The infusion control device according to claim 2, wherein said input unit comprises at least one of a touch display, buttons and a numeric unit.

8. The infusion control device according to claim 1, wherein said securing unit is provided with an indentation configured to hold a circumferential rim of said transparent drip chamber.

9. The infusion control device according to claim 8, wherein said securing unit is a through-hole configured to receive and secure said infusion tube and said transparent drip chamber.

10. The infusion control device according to claim 8, wherein said securing unit is a recess configured to receive and secure said infusion tube and said transparent drip chamber.

11. The infusion control device according claim 1, wherein said light indicator is a light emitting diode.

12. The infusion control device according to claim 1, wherein a material of said infusion bottle is configured to re-emit absorbed light from said light indicator.
