Periodmed PIU1A

General diagnostic wards and emergency departments represent the primary setting for the PIU1A. Its 40–300 mm depth range and nine-mode frequency suite enable FAST examinations, abdominal organ assessment, pleural effusion detection, and acute vascular screening across the full range of adult body types without a cart. The four harmonic modes maintain image quality in high-BMI, steatotic, and post-surgical patients, where fundamental imaging is insufficient. Medigear.uk supports departmental procurement with full specification documentation and volume pricing for emergency and general medicine fleet purchasing.

Obstetric and gynaecological services use the PIU1A throughout the antenatal and gynaecological care pathway. The frequency range from 2.5 MHz for deep obstetric penetration through H6.0 MHz harmonic covers fetal biometry, placental location, liquor assessment, and uterine and ovarian evaluation across a wide patient population. PW Doppler to ±120 cm and colour flow to ±76 cm support standard umbilical and uterine artery Doppler studies. Community midwifery and mobile obstetric services benefit from the PIU1A's wireless design and 60-minute charge cycle. Medigear.uk can advise on fleet configurations for purchasing obstetric services.

Intensive care and high-dependency units benefit from the cableless wireless design in environments where ventilators and monitoring equipment occupy bedside space. Abdominal organ perfusion, inferior vena cava collapsibility, and pleural and ascitic fluid mapping can be achieved without patient transfer. The harmonic suite improves image quality in critically ill patients with suboptimal acoustic windows — a specific clinical consideration in the ICU setting.

Specialist outpatient teams in gastroenterology, urology, and oncology use the PIU1A for structured assessment of the abdomen and pelvic organs, as well as for tumour surveillance. Nine frequency modes provide imaging control across diverse organ depths and patient presentations. Community practitioners benefit from Android/iOS/Windows compatibility and a 3200 mAh battery recharged in 60 minutes. Medigear.uk provides purchasing and after-sales support for all buyer types.

Nine Frequency Modes — The Most Comprehensive Convex Frequency Suite in the Intelligent Series

The PIU1A offers five fundamental frequencies (2.5, 3.5, 4.0, 5.0, 6.0 MHz) and four harmonic modes (H3.6, H4.0, H5.0, H6.0 MHz) — nine selectable imaging frequencies in a single wireless convex probe. This breadth gives clinicians precise penetration-resolution and contrast-artefact control across the full range of abdominal, obstetric, and pelvic imaging scenarios without changing the probe. For departments serving a mixed patient population with varying body habitus and imaging demands, this frequency range is a direct clinical advantage.

Four Harmonic Modes for Contrast Improvement Across the Full Depth Range

Harmonic modes at H3.6, H4.0, H5.0, and H6.0 MHz detect the second harmonic, reducing side-lobe artefacts and improving tissue boundary definition. The four-mode harmonic suite provides imaging flexibility from deeper abdominal penetration at H3.6 MHz through to enhanced near-field contrast at H6.0 MHz. This is particularly valuable in high-BMI patients, with hepatic steatosis, post-surgical anatomy, and gaseous abdominal content, where fundamental imaging alone produces suboptimal contrast. Medigear.uk can confirm the applicability of harmonic mode for specific clinical populations on request.

40–300 mm Depth Range for Near-Field to Deep-Field Convex Coverage

A depth range starting at 40 mm — 20 mm shallower than many comparable convex probes — extends the PIU1A's clinical scope to paediatric and neonatal abdominal imaging, thin-patient anterior wall assessment, and near-field organ evaluation alongside standard adult deep abdominal work. The 300 mm maximum depth covers the full scope of adult abdominal, pelvic, and obstetric convex imaging without depth restriction.

CE-Certified Compliance for Hospital and Institutional Procurement

CE certification confirms that the PIU1A meets the applicable Medical Device Directive requirements across its full frequency range and mode suite. This is the primary compliance requirement for hospital and institutional clinical procurement, and the PIU1A satisfies it without restriction. You can find the declaration of conformity and the full technical file on Medigear.uk, giving governance teams a clean, auditable compliance evidence trail for equipment approval.

PW Doppler (±120 cm) and Colour Flow (±76 cm) for Standard Abdominal Vascular Assessment

PW Doppler to ±120 cm and colour flow to ±76 cm cover the Doppler requirements of portal venous, hepatic, abdominal aortic, and obstetric assessments in standard adult patients. The short-range ±15 cm PW and ±8 cm colour flow settings add precision for near-field flow measurement in superficial abdominal vessels and paediatric vascular anatomy. Together, these range options make the PIU1A appropriate across both general and specialist abdominal Doppler workflows.

Wireless Self-Contained Design for Mobile and Multi-Department Deployment

The PIU1A's cableless wireless design, Android/iOS/Windows connectivity, and 3200 mAh battery recharged in 60 minutes make it fully operational without a fixed imaging infrastructure. For mobile clinical teams, community practitioners, and departments deploying across multiple clinical areas, this eliminates the logistical barriers associated with cart-based convex imaging. Medigear.uk supports multi-unit and fleet procurement for departments standardising on wireless convex imaging across sites.

Android, iOS, and Windows Compatibility With DICOM Output

The PIU1A connects wirelessly to any smartphone, tablet, or laptop, removing the need for a proprietary display terminal. DICOM output enables direct PACS integration and structured clinical reporting. BMP and JPG export support telemedicine, training documentation, and clinical audit. For distributors, platform-agnostic connectivity helps you reach a broader buyer base across all device preferences. Medigear.uk supports IT governance documentation for institutional DICOM integration.

Scalable From Individual Practitioner to Full Departmental Fleet

The PIU1A is available through Medigear.uk for individual clinical purchase and bulk institutional or distributor supply. OEM arrangements support branded portfolio integration. Whether you're equipping a single community practitioner, an obstetric service, an emergency department, or a multi-site health network, the PIU1A's frequency, breadth, and supply flexibility meet your wireless convex probe procurement needs.

Part of the Intelligent Series — Complementary to the Wider Periodmed Portfolio

The PIU1A is one of eight models in the Intelligent Series (PIU1A/1B/1C/1D/2A/2B/2E/2F), which covers convex, linear, and phased-array probe types across varying specifications. If you're building a complete wireless imaging portfolio, you can source complementary Intelligent Series and Aura Series models through Medigear.uk, with consistent after-sales support and procurement documentation across the full Periodmed product range.

128-Element Convex Transducer

The PIU1A's 128-element convex array provides the aperture and element density required for diagnostic-grade beamforming across a depth range of 40–300 mm. This element count supports the probe's nine-mode frequency suite, including four harmonic modes. He enables the PW Doppler range of ±120 cm and colour flow to ±76 cm, both of which are required for adult abdominal and obstetric clinical work.

Fundamental Frequency Range: 2.5–6.0 MHz (Five Selectable Frequencies)

Five selectable fundamental frequencies — 2.5, 3.5, 4.0, 5.0, and 6.0 MHz — span the complete penetration-resolution spectrum for convex probe abdominal and obstetric imaging. The 2.5 MHz lower limit enables deep penetration in high-BMI and late-obstetric patients, while 6.0 MHz improves near-field resolution for paediatric and thin-patient abdominal assessment.

Harmonic Imaging Modes: H3.6, H4.0, H5.0, H6.0 MHz

Four harmonic modes cover the full depth and frequency range of the PIU1A's clinical applications. H3.6 and H4.0 MHz provide harmonic contrast improvement in deeper abdominal structures, while H5.0 and H6.0 MHz deliver near-field harmonic imaging for superficial abdominal, obstetric, and paediatric applications. This four-mode harmonic suite is the most extensive in the Intelligent Series convex configuration.

Imaging Depth: 40–300 mm

A 40–300 mm depth range extends the PIU1A's clinical scope beyond standard convex probes, beginning at 40 mm for near-field paediatric and thin-patient imaging and reaching 300 mm for deep abdominal and obstetric assessment. This range is consistent across all nine frequency modes.

Dynamic Range: 36–120 dB

A consistent 36–120 dB dynamic range across all frequency and harmonic mode selections ensures predictable image contrast and tissue differentiation throughout the clinical workflow.

Gain: 1–100%

Full 1–100% gain adjustment across all imaging and Doppler modes gives clinicians complete brightness control for individual patients, body habitus types, and imaging depths, matching the gain range of full-size cart-based convex systems.

8-Segment Time Gain Compensation (TGC)

Eight independent depth-zone TGC controls allow gain correction at each tissue level across the 40–300 mm depth range, enabling independent optimisation of near-field and far-field structures within the same image frame — a standard requirement for diagnostic-grade abdominal and obstetric convex imaging.

Single Optimised Transmit Focus

The PIU1A uses a single transmit focus optimised for the convex probe's abdominal imaging depth range, providing consistent beam quality across the 40–300 mm clinical window. This focus configuration is well-suited to the wide depth, multi-application clinical scope of the Intelligent Series convex probe.

PW Doppler Range: ±15 cm / ±120 cm

Two selectable PW Doppler ranges — ±15 cm for near-field superficial vessel assessment and ±120 cm for deep abdominal venous, aortic, and obstetric Doppler — provide velocity scale flexibility across the full clinical scope of the PIU1A. Both ranges cover standard adult Doppler workflows without aliasing in typical clinical presentations.

Colour Flow Doppler Range: ±8 cm / ±76 cm

Two colour flow ranges — ±8 cm for near-field small-vessel colour mapping and ±76 cm for deep abdominal and obstetric colour flow — allow the operator to precisely match the velocity scale to the clinical target. The ±8 cm short-range setting is particularly useful for paediatric and superficial abdominal vascular assessment.

Display Modes: B, CF, PW, M, PDI, DPDI

The full mode set covers all standard diagnostic and Doppler requirements for general abdominal, obstetric, urological, and emergency convex imaging. PDI and DPDI provide power Doppler sensitivity for detecting low-flow vessels and assessing directional flow. M-mode supports temporal motion assessment for obstetric and neonatal cardiac applications within the convex probe's depth range.

Spot Reduction: On/Off

Switchable spot reduction reduces speckle noise, improving the visual clarity of tissue boundaries and organ interfaces without permanently altering the underlying image data — useful in abdominal and obstetric imaging, where clean boundary definition aids diagnostic confidence and measurement accuracy.

3200 mAh Battery with 60-Minute Wireless Fast Charging

The 3200 mAh lithium cell reaches full charge in 60 minutes via wireless induction, with 43% restored in 30 minutes for rapid interim top-ups between clinical sessions. Wireless charging eliminates exposed contacts, maintaining probe housing integrity over repeated charge cycles throughout the device's operational lifetime.

Android, iOS, and Windows Wireless Connectivity with DICOM, BMP, and JPG Output

Wireless connectivity to Android, iOS, and Windows removes the need for a proprietary display unit. DICOM output supports PACS integration and structured clinical reporting. BMP and JPG support telemedicine and training documentation across all nine imaging modes. Medigear.uk supports IT governance documentation for institutional DICOM integration as part of procurement planning.
