Global Healthcare Medical 2-in-1 Palm Doppler Ultrasound Scanner
Global Healthcare Medical 2-in-1 Palm Doppler Ultrasound Scanner
Model: GHM 4HL HK
The Global Healthcare Medical 2-in-1 Palm Doppler Ultrasound Scanner is a compact, probe-type diagnostic imaging system that integrates two high-frequency linear array modes into a single handheld device. Weighing just 120g (approximately 0.26 lbs) and measuring 110mm × 50mm × 18mm, this ultra-light scanner puts two essential imaging capabilities directly in your hand—eliminating the need to carry or switch between separate probes during clinical examinations.
The system operates wirelessly via WiFi, transmitting real-time images directly to your iOS, Android, or Windows smartphone, tablet, or PC. With a built-in 2600mAh lithium battery providing up to 2 hours of continuous working time, this scanner is designed for the demands of busy clinical environments—from bedside assessments and vascular access procedures to musculoskeletal evaluations and small parts imaging.
This system is intended for use by trained healthcare professionals. It supports a wide range of diagnostic applications including vascular, musculoskeletal, small parts, nerve, and pediatric imaging.
Key Features & Benefits
2-in-1 Design – Dual Linear Frequencies in One Device
Unlike single-probe systems that require you to switch transducers for different applications, this device features an integrated 2-in-1 design combining two linear array frequency configurations in a single unit. This dual-mode capability allows seamless switching between:
| Mode | Frequency | Scan Depth | Scan Width | Primary Applications |
|---|---|---|---|---|
| High-Frequency Mode | 16 MHz / 20 MHz | 10 – 40 mm | L18 | Ultra-superficial structures: skin, subcutaneous tissue, small nerves, superficial tendons |
| Standard Mode | 7.5 MHz / 10 MHz | 20 – 100 mm | L25 | Vascular, musculoskeletal, small parts, and superficial structure imaging |
This dual-frequency capability makes the scanner equally suited for ultra-high-resolution near-field assessment and standard-depth vascular or musculoskeletal imaging—all from a single pocket-sized device.
High-Performance Imaging with 96 Elements
The scanner is equipped with 96 piezoelectric elements and 32 channels, delivering high-quality imaging across a broad range of clinical applications:
| Specification | Detail |
|---|---|
| Scan Mode | Electronic Array Linear scanning |
| Frequency | 16 MHz / 20 MHz and 7.5 MHz / 10 MHz |
| Elements | 96 piezoelectric elements |
| Channels | 32 |
| Scanning Depth | 10 – 40 mm and 20 – 100 mm (adjustable) |
| Scan Width | L25 / L40 |
| Image Frame Rate | 18 frames/second |
The adjustable scanning depth allows you to adapt the imaging depth to the specific clinical application—from the most superficial structures such as skin, subcutaneous tissue, and small peripheral nerves to deeper musculoskeletal and vascular targets.
Imaging modes supported:
-
B‑Mode – fundamental 2D imaging with 256-level gray scale
-
B/M Mode – combined anatomical and motion imaging
-
Color Doppler – real-time blood flow visualization
-
Power Doppler Imaging (PDI) – sensitive low-flow detection
-
Pulsed Wave Doppler (PW) – quantitative blood flow velocity assessment
Image adjustment features include Gain (30–105 dB), Dynamic Range (40–110 across 8 settings), Focus, Depth, and Noise Reduction (0–4 levels). These adjustments allow clinicians to optimize image quality for different tissue types and patient conditions.
Puncture Assistance for Guided Procedures
The system includes a suite of puncture assistance tools, making it a practical tool for ultrasound-guided interventions:
-
In-plane puncture guide line – for precise needle alignment within the scan plane
-
Out-of-plane puncture guide – with automatic vascular measurement function
-
Needle point enhancement – improved visualization of the needle tip for accurate guidance
These features are particularly valuable for vascular access procedures, where real-time needle visualization is critical. Evidence supports that POCUS-guided peripheral intravenous access in patients with difficult venous access significantly improves success rates and first-attempt success compared to traditional palpation methods.
Wireless Freedom for Point-of-Care Imaging
The scanner connects wirelessly to your mobile device or PC, offering:
-
Real-time image display – instant visualization on your existing screen
-
Image/video storage – save directly to your mobile phone or tablet
-
Broad compatibility – works with iOS, Android, and Windows devices
Extended Battery Life for Clinical Sessions
The system features a built-in 2600mAh lithium battery providing approximately 2 hours of continuous working time—sufficient for extended bedside rounds, vascular access clinics, and musculoskeletal assessment sessions.
Comprehensive Measurement Capabilities
-
Measurements – distance, area, and obstetric calculations
-
Image gray scale – 256 levels for detailed tissue differentiation
