A.T.S.® 4000 and 2200 Tourniquet Systems

Delivering Patient-Specific Pressure

The goal of Zimmer Biomet’s surgical tourniquet systems is not just to stop patient blood flow – it’s to deliver the minimum amount of tourniquet pressure at a specific time, with a specific cuff, for a specific limb. Available with disposable or re-usable cuff options, our exclusive technology calculates the patient’s pressure at an individual level and then applies the minimum amount of tourniquet pressure needed to occlude the limb.

Line Occlusion Detection (Acoustic Reflectometry)

Intended to help identify a line occlusion between the machine and cuff, the technology aims to decrease the unintentional risk of leaving pressure in a tourniquet cuff.

Cuff Alert

Designed to prevent setting the unit to 'standby' with pressure in the tourniquet cuff.

Automatic IVRA Cuff Lock Out

Intended to prevent accidental dual cuff release. Without additional steps or notification, the machine will prompt users to confirm the internet to deflate a second cuff. Improper deflations have resulted in serious injuries and death.

Advanced Leak Detection

Monitors cuffs for minor variations intraoperatively with the intention of reporting potential cuff/hose leaks.

Pre-Op Cuff Test

Allows for bedside testing of cuff pre-operatively to ensure proper function.

Personalised Pressure® Technology

Personalised pressure can help surgeons choose a more individual, often lower, cuff pressure. Lower tourniquet cuff pressure is intended to reduce post-operative wound complications after TKA.1

Applying lower tourniquet pressure has been found to result in less post-operative pain. One study demonstrated that an average thigh tourniquet pressure of 230mmHG resulted in statistically significant lower pain over a multi-day recovery period versus a tourniquet pressure of 350mmHG. 2

Minimising tourniquet pressure and pressure gradients by using Personalised Pressure helps minimise the risk of nerve-related injuries.3


No two patients are the same – that’s why our market leading tourniquet system, the A.T.S. 4000, treats every patient with Personalized Pressure Technology.

Absolute Minimum

L.O.P. Technology was designed to calculate a patient’s pressure at an individual level and apply the minimum amount of tourniquet pressure needed to occlude a limb at a specific time for a specific patient.

Bloodless Field

Tourniquet cuff pressures that are too low could result in bleeding distal to the cuff which can result in undesirable blood in the surgical field and blood loss. Hence, setting tourniquet pressures too low can cause pooling of blood in the field.


The A.T.S. 4000 Automatic Tourniquet System prioritises quick setup, user-friendly operation, and reduced tourniquet pressures. Healthcare professionals can easily set cuff pressures while retaining control over the final pressure setting.
