Three simultaneous network connections, medical device stops working

Please note that I only have very basic knowledge on networking.

Our medical staff work remote on laptops when they see patients and have three network connections at the same time which they all need to do their jobs:

​

1. 4G router for internet access (DHCP)
2. Medical device that sends images to a shared folder on the laptop (based on fixed IP via USB-UTP Dongle)
3. VPN connection (Cisco Anyconnect software)

The issue we have is that the medical device stops working when we enable VPN.

Our best guess is that the medical device no longer "sees" the laptop in the network. When we disable the VPN and restart the medical device it is working again.

See the image below for more information.
