Abstract
The present application is directed to a feeding tube in particular for total parental nutrition and/or medicine dosing. The feeding tube functionality is combined with internal monitoring of vital functions, such as ECG, PH, etc. The position of the electrodes is essential for measuring the optimal signal. In the present application the optimal position is determined by measuring the inversion point of the ECG signal. During insertion of the catheter or modified feeding tube the ECG signal is continuously monitored. Via an acoustic signal the strength of the signal is notable. This enables the nursing staff a simple control of the insertion process.
Claims15
A feeding tube for at least one of total parental nutrition and medicine dosing of a patient comprising:
- a tubular member configured to carry at least one of nutrients and medicine;
- at least one sensor interconnected to the tubular member for internal monitoring of a patient's vital functions, one of the sensors being connected with an ECG signal monitoring device which continuously monitors an ECG signal of the patient;
- and the ECG signal monitoring device using the ECG signal for positioning the feeding tube in an esophagus of the patient in an optimal position;
- wherein the ECG signal is measured as a function of the position of the feeding tube and an inversion of the ECG signal indicates a position, which acts as a reference position from which the feeding tube is moved a pre-specified distance within the patient's esophagus to reach the optimal position;
- and wherein the ECG signal monitoring device generates an acoustic signal in response to the feeding tube position crossing an inversion point of the ECG signal.
A non-invasive patient assessment and monitoring system for total parental nutrition and/or medicine dosing comprising:
- a feeding tube including a plurality of sensors for internally and continuously monitoring an ECG signal of a patient;
- an electronic monitoring system which receives data from the sensors and includes a positioning assisting monitor and an acoustic signal generator, wherein while placing the feeding tube into an esophagus of the patient, the ECG signal is displayed at the monitor and a sound is generated by said acoustic signal generator in response to the at least one electrode reaching a point in the esophagus in which the ECG-signal inverts.
A method comprising:
- inserting a feeding tube into an esophagus;
- during insertion, monitoring a patient's ECG signal using at least one sensor interconnected to the feeding tube;
- determining a position of the feeding tube utilizing the monitored ECG signal, the ECG signal being measured as a function of a position of the feeding tube in the esophagus;
- and
- generating an audio signal in response to upon detection of the feeding tube approaching an optimal position.
