Simple Interaction

Redefining the User Experience of Medical Imaging Systems

Medical imaging professionals use devices like writers use a pen: they are integral to their everyday work. The question we set out to answer was, how do we make devices which are intuitive and user-friendly, rather than a burden? Mindray’s cutting-edge MIS design stems from an in-depth study of medical imaging scenarios. It seeks to optimize user and device interaction and bring ease, convenience, and confidence to technicians’ daily work.

A smoother dialogue
with the machine

"Our interface design aims to take every single clinical scenario into account. Considering the various needs of medical staff at the patients’ bedside and in the POC clinical department, we integrate different interface models to cater to a wider range of clinical scenarios."

- Zhang Qi, industrial designer

More Screen, less work

While designing the MX series, Mindray design team found that when medical professionals used ultrasound devices, they often needed to check the battery level when the device was in standby mode or had been shut down. Just as when checking the time on a mobile phone, it was necessary yet troublesome to wake the device repeatedly. In addition, medical professionals in each department pasted various identification labels on the device, which were neither appealing nor stayed in place very well. The three-screen design, especially the screen that displays battery percentage, has made customization with labels much easier.

New opportunities for voice control

To prevent cross infection and make the interface interaction even smarter and faster, the Mindray design team equipped the TE7 with voice recognition. Clinicians can activate the voice recognition component of iVocal by selecting the iVocal feature on the system and then tapping the Play button. With these simple clicks, the TE7 is all set to perform its tasks as assigned by the operator via voice command, and medical staff can now save time for clinical tasks and avoid touching the screen to reduce the infection risk. The application of voice control technology in ultrasound devices marks a big step forward for the ultrasound workflow.

Prepared for different habits and needs

The design team consider the different needs of medical professionals in the ICU, at the patients’ bedside, and in the imaging department, and provided portable ultrasound users with customized control panel design models – fully touchscreen, mechanical + touch, and fully mechanical. This allows users to choose the model that they feel most comfortable with. Another typical customization in ultrasound design is the use of electronic ink. In a hospital, different departments often share the same ultrasound device. Since different ultrasound procedures follow different protocols, it was the design team’s task to develop focused and customized point-of-care protocols to reduce exam times. As a result, the design team introduced electronic ink to the ultrasound system, which clinicians can use to define the functions on display themselves, making the imaging performance faster and easier.

Maximum comfort
through intuitive interactions

"No detail is too small. To find possibilities to improve human-device interaction, I often carried a portable ultrasound and walked around the hospital with medical staff."

- Zhao Jinzhou, industrial designer

Making mobile DR
more mobile

Medical staff often find it hard to carry bulky mobile DR to patients’ bedsides for X-ray examination. To optimize the user experience, the design team looked for ways to make the MobiEye 700 more flexible and intelligent. With its compact size, unique bionic manipulator, intelligent speed regulation, multiple control mode, and maximum examination coverage, medical staff can now easily move and turn the Mobile Radiography System one-handed. The anti-collision design, detector security technology, exposure status LED indicator, superior battery capacity and auto/manual motion mode also guarantee the machine's reliability. The design of the MobiEye 700 not only breaks the stereotype of bulkiness for traditional mobile DR systems, it also overturns the concept of inefficiency linked to bedside X-ray examinations. Moreover, the patented energy management system is designed to contribute to a greener environment.

Keeping everything
in the basket

Portable ultrasound systems are often transferred to different floors and buildings. The documents placed in the trolley storage basket can be blown away by the wind or soaked by the rain. In response, the team designed a storage basket that can be freely modified. The upper tray can be used as the lid of the lower storage basket to prevent items from falling out, and increase the storage space compared to the previous design.

Taking everyone
into count

Ergonomic comfort and safety was a primary focus when the design team developed the MX series. Considering the various body sizes from Asian female to Caucasian male, as well as different clinical scenarios where the device is used, the design team determined the ideal height of the trolley, but ensured that it could be adjusted to the widest range of clinical settings and heights.

Managing cables
more conveniently

One of the biggest challenges for medical professionals performing ventilation therapies is to assess and regulate the flow rate of liquids and gases within pipes and tubes. Even a single error might put patients’ lives in danger. When the design team created the SV800, we considered the different habits and clinical scenarios of medical professionals as they performed ventilation therapies for better interaction, and provided users with visual operation guidance. Besides, to prevent misoperation, we designed a consistent and intuitive user interface design logic for multiple therapy models. 90 percent operation can be conducted in one step.

Moreover, we also leave a certain degree of flexibility for personalization. The customizable control panel design allows healthcare professionals to set the most commonly used function as a quick command, and arrange ventilation modes according to the frequency of use, so that the device can better adapt to people rather than people to adapt to the device. As a result, medical staff can operate the ventilator in the way they are most accustomed to, leaving more time and energy for the patient.

In today's fast-paced and crowded hospital settings, clinicians are challenged to deliver accurate patient assessments rapidly and to perform routine interventions quickly and effectively. Through close-knit work with medical professionals and Mindray R&D teams, as well as careful observation and repetitive tests, Mindray’s design team optimizes user experience for clinicians. With a human-centric design philosophy at the heart of what we do, Mindray will continue designing medical imaging devices that elevate human-device and interface interactions, making healthcare providers' lives easier and allowing them to deliver better care to patients.
