Leltek LK128M

Neonatal and paediatric units use the LK128M where the infant already is. The operator takes the probe to the cot, opens the app on a paired screen and begins with the Neonatal preset. Through the anterior fontanelle, the microconvex face shows the head structures, and the manufacturer lists neonatal head among the clinical applications.

Cardiac and abdominal work follow the same sequence. Paediatric cardiac is a listed application, and the contact face sits between the ribs of a small chest while M-mode, colour Doppler and power Doppler show motion and flow. The Paediatric preset, with the listed abdomen and difficult abdomen applications, covers the abdomen, and the 12.6 cm depth reaches the organs of school-age children. Operators watch flow and motion on the same screen while the probe stays in place.

Small parts services use the Small Parts preset on superficial structures. The FDA clearance also lists fetal, urology, musculoskeletal, obstetric, and gynaecological indications, allowing the probe to be used in general outpatient rooms as well as specialist units. Presets and measurement tools sit inside one app, so a team learns a single routine, and every operator follows it from the first scan to the last in a session.

Qualified physicians, sonographers and trained clinical staff operate the probe from the app. Because the battery, array, and wireless link all sit in the probe, a ward round, clinic list, or transfer between units requires a screen to follow. Optional DICOM 3.0 supports sites that archive their studies.

The scanner travels to the patient

At 218 g and 178 × 57 × 31 mm, the whole instrument moves in one hand. Staff carry it to a cot, bay, or bedside and start the examination on the spot.

One connection before the first image

Pairing with a screen is the single set-up step. The operator connects the probe via Wi-Fi, selects a preset, and scans, shortening the time between arrival and image.

A 100° field from a small contact face

The array fans scan lines across 100° from a compact face. Operators see a broad slice of anatomy through an infant's narrow windows.

Presets that set the starting point

Small Parts, Neonatal and Paediatric presets load settings for the target. The operator begins from a sensible position and refines as the study continues.

Head and heart on one probe

Neonatal head and paediatric cardiac are both listed applications. A single wireless probe therefore serves two of the most frequent infant examinations.

Doppler included as standard

Colour Doppler and power Doppler are part of the standard configuration. Flow appears over the grey-scale image in the same app.

The screen the room already has

Android, iOS and Windows devices all pair with the probe. A site chooses the phone, tablet or laptop that suits the room and keeps its existing hardware in use.

Two hours of work in a sealed body

The built-in battery supports up to 2 hours of use, and the IP68 body withstands gel and regular cleaning between patients.

FDA 510(k) clearance and declared standards

FDA 510(k) clearance K241161 names the LK128M. The manufacturer declares 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 software life cycle.

Microconvex array of 128 elements

The array holds 128 elements at a pitch of 0.204 mm. Its curved face keeps the contact area small while the beam opens beneath it.

Operating range of 3.6–8.5 MHz

The range suits the shallow depths of small bodies and reaches deeper structures when a study calls for it. Each preset chooses its own working frequency inside the span.

Field of view of 100°

Scan lines fan across 100°, so structures on both sides of the centre line appear together on the screen.

Depth of 12.6 cm

Imaging reaches 12.6 cm beneath the probe face, enough for the head, chest and abdomen of infants and children.

Elevation focus at 4 cm

Slice thickness is tightest at 4 cm, the zone where many neonatal and paediatric structures sit.

Small Parts, Neonatal and Paediatric presets

Each preset supplies a starting configuration for its target. The operator adjusts it as the study proceeds.

Clinical measurement tools

The app offers tools that read distances and other values from a frozen frame. They come with the standard configuration.

B-mode and M-mode

B-mode forms the grey-scale picture behind each preset. M-mode records one scan line over time, so you can time heart walls and valves.

Colour and power Doppler

Colour Doppler displays blood flow direction, and power Doppler detects the presence of flow. Both are standard.

Optional pulsed-wave Doppler

This option measures flow velocity at a selected sample point and plots it as a spectrum through the existing probe.

Optional DICOM 3.0

DICOM 3.0 is an optional extra for sites that file studies in an archive.

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 working time, with time to recharge between patients.

IP68 body at 218 g

The sealed body is rated IP68 and weighs 218 g. Its outer dimensions of 178 × 57 × 31 mm suit one-handed use through a full list.

Real-time upgrades

App and firmware upgrades arrive in real time, so new features reach each unit on a site through the app.

The LK128M suits neonatal, paediatric and small parts services that want the examination to start at the patient. Its strongest case is the workflow: a 218 g probe, a single pairing step and a 100° field through a microconvex face. Presets for Small Parts, Neonatal and Paediatric work, colour and power Doppler, and listed head and cardiac applications all sit on the one array. Staff keep the screens they own, because they pair with Android, iOS, and Windows devices. Up to 2 hours of battery life and an IP68 body suit make it a reliable workhorse. Real-time upgrades keep the software current. The probe measures 178 × 57 × 31 mm and is named in FDA 510(k) clearance K241161.
