Adding computing capabilities to medical carts to bring information and treatments closer to the patient
The medical industry has kept pace with recent technology trends in automation, the Internet of Things, and edge computing. Medical carts are a clear example of how computing capabilities are introduced closer to the user to improve performance and efficiency. Used in emergency rooms, treatment rooms, and patient rooms, these carts translate directly into better care: doctors are better equipped to administer treatment and access information at the point of need.
Sourcing the right hardware for medical carts introduces several challenges that are easy to underestimate. This post covers the ones that matter most.
Space, processing power, touch reliability, ergonomics, and compliance all have to work together, not in isolation.Space Constraints
Medical carts need to be portable and maneuverable. They also need to store medicines and equipment, which means computing capabilities have to fit the smallest footprint possible.
- All-in-one computers solve the footprint problem. No separate peripherals required. The monitor and CPU work together within the same chassis, freeing up cart surface for medicines and equipment instead of computing hardware.
- AIOs beat laptops for cart use. A laptop still needs space on top of the cart. An AIO is designed as a complete system that integrates seamlessly into the cart's footprint.
- Single-device inventory is easier to manage. Managing one integrated device per cart is simpler than tracking two or three separate components across a fleet of carts.
Processing Capabilities
Most medical devices undergo certification processes to prove they are safe to use around or on patients. These processes are expensive and time consuming, which makes the processing decision a long-term commitment, not a yearly refresh.
When sourcing computers for medical carts, start by clearly defining the processing capabilities required to run your applications under typical operating conditions. Once you know the minimum processor and RAM your software needs, look closely at how the manufacturer supports the platform over time.
Ask whether the manufacturer offers extended lifecycle support through version control, rather than a standard short commercial refresh cycle. Hardware manufacturers that manage lifecycle deliberately can keep a validated platform available far longer, which matters when recertification is expensive and time consuming.
If you are designing a completely new cart, it often makes sense to spec the latest processor available with the largest practical amount of RAM. That gives your customer room to grow and ensures the hardware can support updated or new software down the line. Diagnostic image review, treatment applications, and patient information systems all need to run concurrently, now and as those workloads grow.
Connectivity and Edge AI
at the Bedside
The computing requirements for medical carts have grown beyond running a single application well. Carts today are expected to support real-time data access, multiple connected devices, and increasingly, AI-assisted tools at the point of care.
- Modern wireless standards matter more than ever. Wi-Fi 6 and Wi-Fi 7 support higher device density and more stable connections in busy clinical environments where dozens of carts, monitors, and mobile devices compete for bandwidth on the same network.
- Edge AI is moving closer to the patient. AI-assisted diagnostic support, image enhancement, and clinical decision tools increasingly run partially or fully at the edge rather than relying solely on a remote server. That shifts compute and connectivity requirements onto the cart itself.
- Bandwidth planning is now part of the hardware conversation. A cart that handles imaging review, video consultation, and EMR access simultaneously needs network hardware and processing headroom sized for that combined load, not just the lightest individual application.
Latest PCAP Touch and
Gloved-Touch Capabilities
Projected Capacitive touch technology (PCAP) was first adopted by the consumer and commercial market in the early 2000s. Because of its optical clarity compared to resistive touch, PCAP started winning over medical applications soon after.
PCAP touch differentiates itself by offering, for most applications, dual touch, rotation, zoom, flip, and multi-touch of up to 10 fingers. By changing the underlying principle from surface capacitance to projected capacitance, this technology enables an accurate, reliable touch point through layers of glass, whether the input comes from a bare finger, a thin latex glove, or a passive stylus.
This matters because, in the past, most clinical workers could not keep their gloves on and still get an accurate touch on the screen. In medical and industrial settings, gloves are a mandatory safety measure, not an option. Improved algorithms in the PCAP touch controller firmware let touchscreen manufacturers tune the projection field for different applications, enabling medical staff to keep gloves on while using the cart's AIO without sacrificing accuracy.
PCAP touch also provides better optical clarity and an improved contrast ratio compared to traditional resistive touch, which adds up to a clearer, more reliable interface for clinical use.
Design and Customization
Ergonomics is critical in the medical industry. In a regular office setting, users sit at a fairly consistent angle and distance from the monitor. In hospitals, clinics, and doctors' offices, medical staff sit or stand at the patient's bedside while using carts for diagnosis or treatment. Cart sizes vary, and so does the height of the staff using them.
That variability means sourcing AIOs that adjust to different mounting options or allow a meaningful level of customization is not optional. On the design side, you may prefer a clean, modern AIO that matches current design language, or you may want a manufacturer that can match the cart's design directly, including materials, colors, and branding.

Certifications and Security
When sourcing computing capabilities for medical carts, research the minimum requirements for protection, certifications, and security before you commit to a platform.
- Physical protection: Most medical carts operate in environments that call for a level of physical protection against harsh conditions. Look for AIOs with front IP65 protection against dust and water ingress to support easy, frequent sanitization.
- Regulatory compliance: Any computer installed in medical equipment needs to comply with the IEC 60601 standard, which sets overall requirements for basic safety and essential performance so that electrical, mechanical, or functional failures do not put patients or medical professionals at risk. Confirm the current edition with your regulatory team, since standards in this family are periodically amended.
- Access security: Most medical carts sit outside restricted areas, where different staff members have access to them throughout a shift. Simple hardware security features and authentication protocols for accessing the unit address this exposure without adding friction to clinical workflows.
