Case Stories
Case① - Application of ECG in PICC intravenous catheterization
Peripheral venous central catheterization (PICC) uses a catheter to puncture from the peripheral arm vein. The catheter goes directly to the large vein near the heart to avoid direct contact between chemotherapy drugs and arm veins. Ultrasound and ECG are added during the PICC catheterization process. Assisted guidance can effectively improve the first-time success rate of PICC.
Determine the tip position of the intracardiac electrographic catheter:
a) As the catheter is slowly advanced into the SVC, the P wave amplitude of the intracardiac electrogram gradually becomes higher and higher (Figure 3b);
b) Continue to deliver the tube, and the intracardiac electrogram shows the maximum amplitude of P wave (Figure 3c);
c) Continue to feed the tube, and when the intracardiac electrogram shows that the P wave is negative and positive, record the electrocardiogram (Figure 3d);
d) Withdraw the catheter to the maximum amplitude of the P wave (Figure 3c), then withdraw 0.5-1 cm, determine the catheter position, and record the electrocardiogram (Figure 3e).

Case② - Application of vital information monitoring in external counterpulsation
External counterpulsation is an auxiliary circulation that mechanically reduces the systolic blood pressure and increases the diastolic blood pressure in the aorta to assist the heart in doing work, improve blood circulation, and increase blood perfusion in the heart, brain, kidneys and other organs. Method: Counterpulsation increases the blood supply of the coronary arteries by increasing the diastolic pressure of the aorta, rescues the ischemic myocardium, and improves the pumping function of the heart. In counterpulsation therapy, it is crucial to fully consider the delay of the counterpulsation device in the correct time window, provide an early and accurate trigger signal, and provide feedback assessment of the degree of counterpulsation.
Witleaf Medical has cooperated with manufacturers of external counterpulsation therapy equipment to develop a pulse volume chart feedback mechanism based on ECG-triggered positioning and has been successful, and is continuing to conduct further long-term efficacy and counterpulsation therapy prescription evaluation research in the hope of gaining greater success in this field. Achievement.

Case③ - Application of Peripheral Arterial Oxygen Saturation Chart in Scientific Research
oxygen saturation monitoring has the characteristics of continuous, non-invasive and rapid. Research shows that there may be differences in different parts of the human body at different times, or pathological differences. Research on the human body's peripheral arterial oxygen saturation distribution map is of great significance to the development of precision medicine.
Witleaf Medical teamed up with partners and clinical experts to jointly develop a peripheral arterial oxygen saturation chart instrument to achieve the drawing of peripheral arterial oxygen saturation maps. For the sake of scientific research rigor, Witleaf Medical uses a zero phase difference design for systemic arterial oxygen saturation and blood perfusion, and strict sampling and alignment of ECG waveforms. The research assistant uses multi-modal analysis to obtain more accurate diagnostic reference information.
