What Is IEC 60601-1 and Why Does It Apply to Touch Screen Displays?<\/h2>\n

\"What<\/p>\n

IEC 60601-1 is the foremost of the international standards for safety published by the IEC that describes essential performance specifications, as well as the basic safety provisions, for medical electrical equipment. This would include various touch screen displays used in patient monitoring, surgical visualization, and diagnostics imaging, as well as other forms of medical electrical equipment.<\/p>\n

Standard 60601-1 has been through several significant revisions since its initial release. Originally, the 1st edition was issued in 1977 which set the basic electrical safety rules for medical devices, followed by the 2nd edition in 1988 with scaling test procedures. Edition 3 in 2005 introduced the risk management structure used for the current version. Currently, the “Edition 3.2” of IEC 60601-1, with 2020 amendment, is what manufacturers must meet for medical touch screen display modules<\/a> and other medical electrical equipment.<\/p>\n

According to the U.S. Food and Drug Administration, the latest IEC 60601-1:Edition 3.2 standard is to be recognized by December 17, 2023. Any new 510(k) submissions after this date are required to reference this newer process. This resolution date is relevant for manufacturers using touch screen monitors as part of a medical device – whether these are patient monitors at the bedside, high-brightness surgical displays in the operating room, diagnostic imaging workstations in radiology, or bedside terminals allowing access to EHRs.<\/p>\n

Touch screen monitors bring additional certification considerations that passive displays do not need. Specifically, the capacitive sensing layer introduces additional electronics, the touch controller element superimposes high frequency signals, and the user interface element is accessible for physically contacting, and sometimes even directly with, the patient. Each of these aspects remains within the scope of IEC 60601-1 certification, which assesses mechanical problems, electrical hazard risks, thermal constraints, and radiation dangers in any device identified as medical electrical equipment<\/a>.<\/p>\n

Since these touch based interfaces are part of the clinical flow – and because practitioners depend upon them to deliver precise patient information – the IEC 60601-1 standard views them as components whose defect could impact patient safety.<\/p>\n

<\/p>\n

Electrical Safety Requirements for Medical Touch Displays<\/h2>\n

Electrical safety underpins the IEC 60601-1 rule set. It details stringent limits for leakage current, insulation resistance, and dielectric strength that must be met by each certified medical device – across normal operation as well as a single fail condition where one protective feature is no longer effective.<\/p>\n

\ud83d\udcd0 Engineering Note \u2014 MOOP vs. MOPP<\/p>\n

Two protection means (MOP) are expected. MOP (Means Of Operator Protection) defends the operator from electrical hazards. MOPP (Means Of Patient Protection) safeguards the patient that is electrically connectable, and possibly directly connected, to the device. For “applied part” classification, the standard allows 10 A of leakage current at the cardiac connection point in the maximum normal situation – reaching the IEC 60601-1 clause 8.7 standard. This difference affects how types of insulation coordination is selected across the entire touch screen module design.<\/p>\n<\/div>\n

Applied parts category guides the strain of leakage current your device needs to abide by. Type B builds up contact with the body but is not isolated from ground. Type BF, also called “Body Floating”, isolates from the ground. Type CF (Cardiac Floating) provides the highest level of isolation, and is applicable to intracardiac catheters for example.<\/p>\n

Getting a PCB Design Right for Medical Touch Display Modules<\/p>\n

One of the most common fails encountered during lab testing of medical touch display modules<\/a> is too little creepage and clearance gaps on the PCB surrounding the touch controller IC. Remember that capacitive touch controllers are often located near the display connector. If the PCB layout does not allow for the 8 mm creepage distance on the underside of the PCB (expected working voltage of 250 VAC + reinforced insulation), the test device will fail dielectric strength testing. Identifying this in pre-compliance labs can save weeks of costly rework.<\/p>\n

Authors Note: The ability to withstand these electrical safety tests is not a matter of choice. A medical electrical device that cannot pass leakage current or dielectric strength cannot go into any regulated market period.<\/p>\n

<\/p>\n

EMC Testing \u2014 IEC 60601-1-2 for Touch Screen Monitors<\/h2>\n

\"EMC<\/p>\n

Electromagnetic compatibility (EMC) testing per IEC 60601-1-2<\/a> confirms that a medical touch screen monitor does not produce harmful electromagnetic emissions or malfunction in a high electromagnetic environment. The most recent version (Edition 4.1, 2020) contains a few new requirements that are pertinent to medical environments where wireless electronic devices are becoming more common than ever.<\/p>\n

Edition 4.1 introduced proximity field testing for RF wireless devices in the vicinity of the medical monitor – smartphones, WiFi routers, Bluetooth gloves, etc.. This test ensures that the medical monitor maintains its critical performance when a wireless transmitter is located near the display (e.g. nurse holding a phone near a patient monitoring touch screen<\/a>).<\/p>\n

<\/p>\n

\n

\u26a0\ufe0f Touch-Specific EMC Risk<\/p>\n

Capacitive touch controllers use high frequency (60-250 kHz) scanning to locate touches. That high frequency couples some noise into circuitry radiated emissions a non-compliant pass will likely have. Make sure the touch FPC cable is shielded with a grounded copper foil layer, and avoid crossing the scanning frequency bands over the usual medical signal frequencies used by EEG\/ECG at approximately 70kHz.<\/p>\n<\/div>\n

Electromagnetic interference within healthcare environments is measured according to whether clinical personnel use the device at home or in a professional healthcare facility. Class A limits are about 10 dB more lenient than Class B limits, because the customer is in a more controlled environment. Consider designing the touch screen monitor<\/a> to meet Class B requirements if your market division plans to win both market segments with the same product line, after all it is generally easier to fulfill a more demanding requirement than to fix it later.<\/p>\n

Translation: EMC can be complex. How the PCB is designed and assembled in combination with the touch screen assembly mounting points influence whether the final product passes its full IEC 60601-1-2 test suite in one shot.<\/p>\n

<\/p>\n

IP Rating, Ingress Protection, and Infection Control<\/h2>\n

Protection from solids and liquids ingress relates to why a common touch screen display that is designed for medical use must have the reliability to keep water, fluids, and dust away from internal circuits, near and during cleaning procedures.<\/p>\n

\n\n\n\n\n\n\n\n

Pro tip – PCAP vs. Resistive: Infection Control<\/p>\n

The sealed PCAP (projected capacitive) touch surfaces allow chemical wipe-down with hospital-grade disinfectants – quaternary ammonium compounds, accelerated hydrogen peroxide, and sodium hypochlorite cleaners. Repeated chemical contact damages resistive touch films which develop delamination and yellowing issues 6-12 months post-application of daily disinfectants. Select PCAP in any area subject to routine disinfection per CDC disinfection guidelines<\/a>.<\/p>\n<\/div>\n

In addition to an IP rating, silver-ion or copper-based antimicrobial coated on the cover glass helps fight healthcare-associated infections. Data from JIS Z 2801 certified testing shows bacterial populations reduced by 99.9% within 24 hours of contact. Additional bacterial load reduction does require hospital disinfection prior to use.<\/p>\n

Mismatching the IP rating to the level of clinical risk can result in a false assurance of protection. Here an IP54 touch display module<\/a> in a high fluid splash environment gives staff false confidence that the display is protected, while an IP67 monitor in a low risk clinical use area adds cost.<\/p>\n

UN Standard IEC 60601-1 is a family of standards, adopted regionally as UL 60601-1<\/a> (US), EN 60601-1 (EU), CAN\/CSA-C22.2 Nos 60601-1 (Canada). Each market version of the standard has adapted to local government regulations, which include national deviations manufacturers must meet. Differences can be significant.<\/p>\n

Third-party testing through TSE (Third-Party certification) such asUL or Intertek provides important distinctions in risk. Acceptance of EN standards by the US FDA is made more straightforward through NRTL accredited testing, although the cost of Redtick_Kzaze is higher. In $10,000-$24,000+, an international test report that regulators quickly accept can be built into the project.<\/p>\n

In the EU, the full requirements of MDR 2017\/745 expects a Notified Body audit of most active medical displays in Class IIa. Self certification as was recently announced for a switch to NIB market will no longer suffice. This added step extended certification pipelines by an additional 3-6 months.<\/p>\n

Multi-market manufacturers should use the IECEE CB Scheme using a IEC 60601-1 certified CB-Test Certificate. Recognition by 54 countries will mean national regulators can accept the results and limit testing to local documents granting local-to-market approval in 12-18 months rather than 36+ months.<\/p>\n

Providers using IEC 60601-compliant touch display assemblies<\/a> in medical PCs and system solutions should verify that the display module carries its own CB report, simplifying certification of the entire system.<\/p>\n
