Product Description

HTSY® Air Compression Therapy System comes in models like the HB-Air902DVT and Airpro series. It’s a non-invasive physical therapy device. It works with a controller, tubing, and multi-chambered air cuffs to deliver cyclic pressure therapy to the limbs. This therapy can be sequential, gradient, or uniform, depending on your needs. It’s widely used to help prevent deep vein thrombosis, ease lymphedema, and support recovery from limb dysfunction caused by stroke, surgery, or injury.

Treatment Mechanism

1. Boost Circulation

HTSY® Air Compression Therapy System features air cuffs that apply gentle waves of pressure—starting at the far ends of the limbs, then moving slowly toward the proximal areas—while delivering a steady, rhythmic deep compression. This slow, wave-like pressing motion boosts the smooth flow and reflux of blood and lymph fluid, easing that familiar achiness and swelling in the legs and feet.

2. Flexible Adaptation to Treatment Rhythms

Multiple pressure modes are available on the HTSY® Air Compression Therapy System, with both treatment duration and pressure intensity adjustable to precise levels, and the Airpro Series takes this flexibility a step further. It can automatically detect the patient's condition and intelligently regulate the inflation and rest cycles, and with its stable pressure output, every treatment is tailored to individual needs for optimal therapeutic effects.

3. Safe, Convenient and Ready for Anytime Use

HTSY® Air Compression Therapy System is built for both user safety and everyday convenience. It’s equipped with built-in overpressure protection, plus a manual emergency pressure release switch to boost safety during use. Easy to operate and ultra-quiet when running, it also comes with a full range of cuff sizes—so it’s a breeze to use for rehab, whether in a clinical environment or the comfort of your home.
