Problems solved by technology
However, inserting the catheter blindly can lead to incorrect catheter placement, ineffective treatment with the catheter, or physical damage to internal organs due to catheter penetration
Also, in many pediatric patients with transcatheter catheterization, the catheter tip is misplaced due to movement of the catheter after insertion

Embodiment Construction
[0053] Aspects of the present disclosure provide a system and method for receiving an electrocardiogram (ECG) signal from the tip of a catheter inserted in a pediatric patient, determining R-peaks in the ECG signal, determining P-peaks in the ECG, and using a trained machine A learning engine determines a position of the catheter in the pediatric patient based at least in part on the P-peak and the R-peak.
[0054] The heart's sinoatrial node generates electrical signals that extend through the body. An electrocardiogram (ECG) signal is a measurement of these electrical signals from the heart. EGG can be measured at various locations in the human body. In pediatric patients, such as neonates, infants, young children, children or adolescents. In smaller patients, such as newborns to young children, the distance from the heart to any other part of the body is small compared to the same distance in adults. Therefore, ECG signals can be easily detected across the patient's enti...

When inserting a catheter or other medical equipment into a child or adolescent or other paediatric patient, ECG signals may be recorded from the catheter and the location of the catheter determined by analysing the ECG signals. A signal processor and user interface may receive recorded signals in real-time from the catheter while the catheter is inserted into the paediatric patient. The signal processor may analyse the ECG signals to determine the location of the catheter in the paediatric patient. The user interface may display the location of the catheter and other pertinent information toa user while the user is inserting the catheter. One method for determining the location may include determining R-wave and P-wave peaks of the ECG signal and determining the location from an averagelocation of the R-wave and P-wave peaks in the ECG signal.
Description
[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 574,403, filed October 19, 2017. technical field [0003] The present disclosure relates to medical devices. More specifically, portions of this disclosure relate to processing signals to determine the position of a catheter in a pediatric patient. Examples of applications of the present disclosure include determining the location of an umbilical catheter in a newborn infant or the location of a central venous catheter in a child or adolescent. Background technique [0004] Central venous catheters (CVCs) are used to infuse fluids and administer medications to pediatric patients such as newborn infants, infants, children, and adolescents. For newborn babies (also known as newborns), the type of CVC used is called an umbilical vein catheter (UVC) because it can be inserted through the umbilical vein, at least a week or so after birth. In t...
