The VsSCan Medical Unit has been specially developed for the rapid and touchless assessment of vital signs as a “first point of contact” to reduce the risk of an infected individual being allowed to enter the general hospital environment, where they could contaminate others.

Every potential patient enters the hospital via a small room which has a controlled environment, in order to have their “vital sign assessment”. This will involve a clinician being in an adjacent (safe) room, but with facility to have direct visual and voice communication with the patient (via a reasonably sized screen, camera and microphone inbuilt into the VsScan unit).  The communication facility would allow a remote discussion and consultation to take place between medic and patient in addition to providing instruction on how to position them correctly for the scan to be successful.

The main vital signs can be routinely assessed, including the following:

  • Body temperature (36.5°C to 37.3°C)
  • Heart rate (60 to 100 beats per minute)
  • Respiration rate (12 to 18 breaths per minute)
  • Oxygen Saturation (%)
  • Systolic Blood Pressure (mmHg)

Depending on results of the assessment of the patient’s condition, they would either be immediately transferred to a specialized isolation unit in order to undergo further tests (if risk of infection) or they would enter the main-stream clinical care facility within the hospital.

VsScan unit consists dynamic real-time screening camera installed on desktop computer with reasonably sized screen. The cameras array is fitted with RGB module, IR projector, two 3D imager sensors and thermal imaging camera. Artificial Intelligence (AI) video analytics software continuously collects data, calculate the vital signs values, display measurement results, compare these results with normal ranges and provide output for Early Warning Score (EWS) calculation. A standalone separate client software enables to establish communication between medic and patient.
