Leltek LK128PA

Cardiology services use the LK128PA for its intended examination. The operator selects the cardiac preset, freezes the four-chamber view at end diastole and at end systole, and turns on the EF measure to receive an automatic ejection fraction. Each step happens in the app, on the paired screen. Colour Doppler and power Doppler add flow to the grey-scale image, and M-mode records valve and wall movement over time.

Emergency and acute care teams use the probe for FAST (focused assessment with sonography in trauma), which the manufacturer lists as a headline application. The 30 cm depth reaches deep abdominal structures, and the lung application suits bedside chest examinations. Abdominal scanning is also listed, so one wireless probe covers several routine questions on a ward round. Because the system is fully wireless, scanning can begin wherever the patient is placed.

Obstetric services use the same probe for mid- and late-pregnancy scans, because the manufacturer lists OB mid and late among its clinical applications. The 90° sector shows the field around the contact point, and the low frequency range carries the beam through deeper tissue.

Qualified physicians, sonographers, and trained clinical staff operate the probe from the app on a paired screen of their choice. That screen can be a phone, tablet or laptop that the site already uses, and optional DICOM 3.0 lets sites that archive studies send images to their imaging record. The 236 g, IP68 body travels between wards, clinic rooms and cardiology lists with the operator.

An ejection fraction from two frozen frames

The operator freezes end diastole and end systole in the four-chamber view, and the app returns EF. The calculation sits inside the standard configuration.

A face narrow enough for the ribs

The phased array sits in the gap between ribs and steers a 90° sector through it. The heart appears from a small contact area.

Depth to 30 cm from a low frequency range

Frequencies from 1.3 to 3.7 MHz reach 30 cm. Deep cardiac and abdominal structures stay within reach.

Cardiac measurement tools in the app

The app includes clinical cardiac measurement tools in the standard configuration. Readings are taken from a frozen frame in the same app that shows the image.

Doppler included as standard

Colour Doppler and power Doppler are part of the standard configuration. The manufacturer highlights the colour Doppler's sensitivity.

Cardiac, FAST, lung and abdominal work on one probe

The manufacturer lists all four among the clinical applications. A single wireless probe therefore moves from the heart to the chest to the abdomen.

The screen the room already has

Android, iOS and Windows devices all pair with the probe. Sites select whichever phone, tablet or laptop is closest to hand, and existing devices stay in service.

Two hours of work in a sealed body

The built-in battery supports up to 2 hours of working time, and the IP68 body tolerates regular cleaning between patients.

FDA 510(k) clearance and a 1-year warranty

FDA 510(k) clearance K241161 names the LK128PA. The manufacturer declares compliance with ANSI/AAMI ES60601-1 for electrical safety, IEC 60601-1-2 for electromagnetic compatibility, IEC 60601-2-37 for ultrasound equipment, IEC 62133-2 for battery safety, and IEC 62304 for the software life cycle, and includes a 1-year warranty.

Phased array of 64 elements

The array holds 64 elements at a pitch of 0.32 mm. Electronic steering fans the beam across the sector from one narrow face.

Operating range of 1.3–3.7 MHz

The low range suits deep imaging of the heart and abdomen. It carries the beam through the chest to the structures behind the ribs.

Field of view of 90°

Scan lines steer across 90°, so structures on both sides of the centre line appear together on the screen.

Depth of 30 cm

Imaging reaches 30 cm beneath the probe face, which covers the heart and the deep abdomen of an adult patient.

Elevation focus at 7 cm

Slice thickness is tightest at 7 cm, the zone where much cardiac anatomy sits.

Automatic EF calculation

With the cardiac preset active, a frozen four-chamber view at end diastole and end systole feeds the EF measure. The app outlines the contours and returns lengths, area and EF.

Clinical cardiac measurement tools

Tools inside the app take distances and other readings from a frozen frame. They belong to the standard configuration.

B-mode and M-mode

B-mode forms the grey-scale picture behind each preset. M-mode traces a single scan line over time, letting the operator time the movement of heart walls and valves.

Colour and power Doppler

Colour Doppler shows blood flow direction, while power Doppler is sensitive to flow itself. Both come as standard.

Optional pulsed-wave Doppler

With this option, you can sample flow velocity at one chosen point and display it as a spectrum on the same probe.

Optional DICOM 3.0

Sites that keep studies in an imaging archive can add DICOM 3.0 as an option.

Wi-Fi 802.11 a/b/g/n at 2.4 and 5 GHz

The probe joins a paired device on either band. Phones, tablets and laptops on Android, iOS and Windows all connect.

Rechargeable battery

A built-in battery supports up to 2 hours of use, with time to recharge between patients.

IP68 body at 236 g

The sealed body is rated IP68 and weighs 236 g. Its outer dimensions of 177 × 57 × 31 mm support one-handed use.

Real-time upgrades and a 1-year warranty

Upgrades to the app and the probe firmware are delivered in real time, so every unit in a site receives new features remotely. A 1-year warranty is part of the standard offer, and an extended warranty is available as an option.

The LK128PA suits cardiology, emergency and general inpatient services that want an ejection fraction and a chest or abdominal view from one wireless probe. Its strongest case is the EF function: two frozen frames of the four-chamber view lead to an automatic result inside the app. A phased face that sits between ribs, a 30 cm depth, colour and power Doppler, and FAST, lung and abdominal applications all sit on the one array. Android, iOS and Windows support lets staff keep the screens they own. The probe weighs 236 g, measures 177 × 57 × 31 mm and is named in FDA 510(k) clearance K241161.
