Ultrasound Patch

Stroke, a prevalent and high-risk cardiovascular and cerebrovascular disease, has long been a key challenge for national health prevention and control. Carotid artery disease is a core contributing factor to stroke. To strengthen the nation's cardiovascular and cerebrovascular health defenses, China's carotid ultrasound screening system has undergone more than a decade of standardized development and is now widely implemented: In 2014, carotid ultrasound was officially included in routine national health checkups; in 2015, a unified national screening standard was issued, forming a standardized and regulated vascular lesion screening system.

Traditional rigid ultrasound probes rely on handheld operation by professionals and only support short-term static testing within hospitals. They cannot capture dynamic changes in blood vessels during daily activities and sleep, making it difficult to detect many hidden and paroxysmal high-risk vascular conditions. This has become a pain point in the industry for the refined management and intensive care of chronic vascular diseases.

Addressing the shortcomings in clinical monitoring and industry needs, Yisheng Micro-Nano relies on its self-developed piezoelectric smart materials and precision transducer manufacturing technology to independently develop a series of flexible patch ultrasound probes. With its core advantages of lightweight, wearable, and all-weather dynamic monitoring, it breaks through the limitations of traditional ultrasound detection and provides a brand-new solution for early screening, risk warning, efficacy follow-up, and intensive care of carotid artery lesions.

Four core clinical values empower precision diagnosis and treatment of blood vessels

Carotid ultrasound is a core non-invasive imaging technique for stroke prevention, management of chronic cardiovascular and cerebrovascular diseases, and critical care in neurology. Yisheng's micro-nano patch ultrasound probe is deeply adapted to all clinical scenarios, achieving comprehensive and precise monitoring:

1. Precise screening for early lesions, quantifying vascular damage: It can dynamically monitor carotid intima-media thickness, vessel diameter, and pulsation waveform, accurately capturing subclinical and progressive atherosclerotic vascular damage. This provides precise quantitative data support for early screening of vascular lesions, risk stratification, and follow-up of treatment efficacy, enabling early detection and early intervention.

2. Dynamic assessment of plaque risk, filling screening blind spots: It can track carotid artery blood flow Doppler signals in real time under different physiological states, such as resting and mild exercise. By quantifying dynamic parameters such as blood flow shear force and blood flow variability, it accurately assesses the risk of unstable and ruptured vulnerable plaques, completely overcoming the shortcomings of traditional static examinations that cannot monitor dynamic blood flow changes.

3. Non-invasive dynamic blood pressure monitoring for accurate prediction of perfusion load

Based on a high-precision vascular blood flow waveform calculation algorithm, it can non-invasively and cufflessly measure central arterial pressure, accurately reproducing the actual perfusion load of cerebral vessels. This is suitable for long-term standardized follow-up of high-risk stroke patients, significantly improving the accuracy of cardiovascular and cerebrovascular disease prevention.

4. Real-time bedside monitoring for early warning of severe illness risks

Suitable for continuous bedside monitoring of inpatients in neurology departments, it monitors the cerebral vascular blood supply status 24 hours a day, providing early warning of adverse events such as vasospasm, insufficient cerebral perfusion, and thrombus re-occlusion, buying valuable time for early clinical intervention and optimizing the long-term prognosis of critically ill patients.

Four major technological advantages that revolutionize traditional monitoring models

Compared to traditional rigid ultrasound probes, the Yisheng Micro-Nano Flexible Patch Ultrasonic Probe represents a comprehensive upgrade in structural design, monitoring modes, applicable scenarios, and data accuracy, perfectly adapting to the full-cycle clinical monitoring needs of the carotid artery:

1. Flexible Conformal Fit for More Stable Detection: Utilizing a lightweight, flexible, and stretchable substrate, it perfectly conforms to the curved anatomical structure of the neck, completely eliminating the gaps and acoustic energy loss issues associated with traditional probes. This effectively improves detection stability and data repeatability, avoiding human error.

2. Hands-Free Fixation Design for All Physiological Scenarios: The innovative adhesive fixation structure eliminates reliance on manual hand operation, adapting to all physiological scenarios including patient rest, sleep, daily activities, and light exercise. This addresses the limitations of traditional ultrasound, which can only perform static, supine detection in the hospital and experiences signal failure during movement, thus restoring dynamic vascular data under true physiological conditions.

3. 24/7 Continuous Monitoring, Capturing Hidden Risks

Breaking through the limitations of traditional short-term appointment-based examinations, it supports uninterrupted data acquisition and automatic transmission around the clock. It can accurately capture diurnal rhythm changes in hemodynamics and central arterial pressure, promptly detecting paroxysmal and occult high-risk vascular abnormalities, and fully reconstructing the progressive and fluctuating development patterns of vascular lesions.

4. Extremely Simple Deployment, Adaptable to Multiple Scenarios, Highly Deployable

The device can be quickly deployed in just 10 minutes. Its lightweight, wireless design eliminates the need to move bedridden patients, making it suitable for diverse scenarios such as in-hospital intensive care, outpatient screening, and long-term home follow-up. It is also suitable for the full-cycle refined management of high-risk stroke populations, with clinical applicability and widespread adoption far exceeding that of traditional ultrasound equipment.
