Product overview

The 7L is a linear wireless ultrasound probe using electronic array scanning, with 192 elements and 32 channels. The host is built into the probe, and images travel over its own WiFi to a phone, tablet or Windows PC, so the unit does not depend on the WiFi available on site.

The frequency is 7.5-10.0 MHz with scanning depth adjustable across 20-100 mm. It keeps the superficial resolution of a linear array while reaching down to 100 mm, so part of the slightly deeper work is covered as well.

Imaging runs in B, B/M, Color, PDI and PW with a gain range of 30-105 dB, and gain, focus, pulse inversion harmonic imaging and noise reduction are adjustable. In-plane needle guidance lines and out-of-plane guidance are supported. Battery life is 1.5 hours, extended by wireless charging at any point. The probe measures 140 x 55 x 20 mm and weighs 180 g.

Typical applications

The application scenarios on this page describe the device based on its technical data and configuration. The actual scope of application is the one stated in the product registration certificate. Follow your institution's procedures and the instructions for use.

Setting / department	Typical use	Configuration note
Anaesthetics and pain management	Visual guidance for deep vein puncture, nerve block and joint injection	High-frequency linear, good superficial resolution
Nursing and vascular access	PICC and CVC insertion and infusion guidance	High-frequency linear
Vascular surgery and nephrology	Vascular access, thrombus and stenosis assessment, puncture guidance	Linear scanning
Rehabilitation, musculoskeletal, thyroid and breast	Musculoskeletal and joint examination, thyroid and breast examination	High-frequency linear

Usage and selection notes

The 7L belongs to the linear series: high frequency penetrates shallowly and resolves superficial structures well, which suits the thyroid, breast, musculoskeletal, nerve, vascular and carotid work. Its frequency is close to the other linear models in the series and the depth steps differ slightly; please confirm the selection with our product department.
