IEC 60601-2-36:2014

Overview

IEC 60601-2-36:2014 is an international standard developed by the International Electrotechnical Commission (IEC) focusing on the basic safety and essential performance of medical electrical equipment used for extracorporeally induced lithotripsy (EIL). This particular standard is part 2-36 of the IEC 60601 series, which targets specific requirements supplementing the general safety standard IEC 60601-1.

Extracorporeally induced lithotripsy is a therapeutic procedure that applies focused pressure pulses outside the body to break down kidney stones and other calculi. IEC 60601-2-36:2014 governs equipment directly involved in EIL, including the pressure pulse generator and patient support device, ensuring safety and performance during clinical use.

This second edition updates and aligns the document structurally with IEC 60601-1:2005 and its amendment 1:2012, superseding the original 1997 edition. It excludes devices like patient treatment planning computers, X-ray and ultrasonic imaging devices, physiotherapy ultrasound equipment, and high-intensity therapeutic ultrasound (HITU) devices, which are regulated by other respective IEC standards.

Key Topics

• Scope and Application
  The standard applies strictly to electrical medical equipment generating extracorporeally induced pressure pulses and their immediate associated components. It excludes diagnostic imaging tools and physiotherapy devices.

• Basic Safety Requirements
  The document sets mandatory safety measures to protect patients and operators from electrical, mechanical, radiation, and temperature-related hazards during lithotripsy treatment.

• Essential Performance Criteria
  Ensures that equipment reliably delivers therapeutic focused pressure pulses with precision in dosing and targeting in line with clinical needs, avoiding hazardous outputs or malfunctions.

• Testing and Classification
  Detailed requirements for equipment testing procedures are outlined to verify compliance. Classification of medical electrical equipment (ME equipment) and medical electrical systems (ME systems) is specified for risk management.

• Electromagnetic Compatibility (EMC)
  Addresses the EMC aspects to minimize electromagnetic interference and ensure proper functioning of lithotripsy devices in medical environments.

• Documentation and Marking
  The standard mandates clear identification, instruction manuals, and labeling to facilitate safe operation and maintenance.

• Programmable Electrical Medical Systems (PEMS)
  Special provisions apply to programmable components within the lithotripsy equipment, emphasizing software safety and fault control.

• Annexes and Guidance
  Informative annexes provide technical rationale, coordinate definitions for focus and target location, and practical implementation guidance.

Applications

IEC 60601-2-36:2014 is crucial for:

• Manufacturers designing and producing extracorporeal lithotripsy machines and related medical devices to ensure conformity with international safety standards.
• Healthcare facilities employing lithotripsy equipment to comply with regulatory requirements for patient and staff safety.
• Regulatory bodies evaluating equipment compliance as part of medical device approval processes worldwide.
• Biomedical engineers and technicians involved in testing, maintenance, and calibration of extracorporeal lithotripsy systems.
• Clinical researchers and developers designing innovation in lithotripsy technologies focused on therapeutic pressure pulse generation.

Implementing this standard supports reducing risks associated with electric shocks, mechanical failures, radiation hazards, and software malfunctions while maintaining treatment efficacy and patient safety.

Related Standards

IEC 60601-2-36:2014 is part of the broader IEC 60601 family addressing medical electrical equipment safety. Key related standards include:

• IEC 60601-1:2005 (Amendment 1:2012) - General requirements for basic safety and essential performance of medical electrical equipment.
• IEC 60601-2-37 - Particular requirements for ultrasonic medical diagnostic and monitoring equipment.
• IEC 60601-1-2 - Requirements for electromagnetic compatibility of medical electrical equipment.
• Standards for Ultrasound Physiotherapy Equipment - Separate standards govern therapeutic ultrasound devices not covered under IEC 60601-2-36.
• ISO/IEC Directives, Part 2 - Guiding principles for drafting and structuring IEC standards.

By integrating the requirements of IEC 60601-2-36 with these complementary standards, stakeholders can achieve comprehensive compliance for devices used in lithotripsy and related therapeutic applications.
