The Zimmer ATS 4000 Automatic Tourniquet System is a state-of-the-art device designed to enhance patient safety and surgical efficiency during procedures requiring limb occlusion. Utilizing Personalized Pressure Technology, it calculates and applies the minimum necessary tourniquet pressure tailored to each patient's specific needs, thereby reducing the risk of postoperative complications and improving overall outcomes. 

Key Features:

• Limb Occlusion Pressure (LOP) Technology: Determines the precise pressure required to occlude blood flow in a patient's limb, ensuring effective hemostasis while minimizing pressure-related injuries. 
• Dual Port, Dual Cuff System: Allows for independent control of two cuffs, facilitating complex procedures such as bilateral surgeries and Intravenous Regional Anesthesia (IVRA). 
• User-Friendly Interface: Features an 8.4-inch color touchscreen display that provides clear, real-time information, simplifying operation for medical professionals. 
• Automatic IVRA Cuff Lockout: Enhances safety by preventing accidental cuff deflation during IVRA procedures, ensuring that both cuffs remain inflated until intentional deflation is confirmed. 
• Self-Check Calibration: Performs automatic calibration checks upon startup to verify system accuracy, reducing setup time and ensuring reliable performance.
• Battery Backup: Equipped with a lithium-ion battery providing up to six hours of operation, maintaining pressure during temporary power interruptions to ensure uninterrupted surgical procedures. 
• Portability: Designed with a carrying handle and pull-out hangers for convenient storage of cuffs and hoses, the lightweight unit can be mounted on an IV pole or placed on a table, offering flexibility across various clinical settings. 

Technical Specifications:

• Pressure Range: Adjustable from 50 to 600 mmHg, with a pressure accuracy of ±3 mmHg, allowing for precise control tailored to individual patient requirements.
• Display: 8.4-inch color touchscreen provides intuitive navigation and clear visualization of settings and real-time data.
• Power Supply: Operates on standard AC power and includes a rechargeable lithium-ion battery for backup, ensuring continuous functionality during power fluctuations. 

By integrating advanced pressure management technologies with user-centric design, the Zimmer ATS 4000 enhances surgical precision and patient safety. Its ability to customize pressure settings based on individual patient characteristics contributes to reduced postoperative pain and a lower risk of nerve-related injuries, making it a valuable asset in modern surgical environments.
