IV fluid control system with fluid runaway prevention
First Claim
Patent Images
1. In an IV fluid control system of a type including an IV set for connection between a source of fluid and a patient, and a control device for receiving and acting upon a portion of the IV set to control fluid flow from the source to the patient;
- the improvement comprising;
means for providing a sensor signal which is a function of a parameter which changes depending on whether there is fluid flow through the IV set; and
means responsive to the sensor signal for providing an indication that the IV set should not be removed from the control device unless the sensor signal indicates that fluid flow through the IV set is stopped.

Abstract
An IV fluid control system having an IV set and a control device (such as an IV controller or fusion pump) includes a flow sensor which senses the flow of fluid through the IV set. Fluid runaway is prevented by an interlock which prevents removal of the IV set from the control device unless the fluid flow through the IV set is stopped. As a result, the medical personnel must clamp the outlet tubing of the IV set to stop fluid flow before removing the IV set from the control device.

9. In an IV fluid control system of a type including an IV set for connection between a source of fluid and a patient, a control device for receiving and acting upon a portion of the IV set to control fluid flow from the source to the patient, and a clamp which is closable to clamp off fluid flow from the portion of the IV set acted upon to the patient;
- the improvement comprising;
means for providing a sensor signal which is a function of a parameter which changes depending on whether the clamp is closed; and means responsive to the sensor signal for providing an indication that the IV set should not be removed from the control device unless the sensor signal indicates that the clamp is closed. - View Dependent Claims (10, 11, 12, 13, 14, 15)
