Medical grade virtual reality cart

Virtual Reality (VR) is a hot topic in the entertainment industry! However, there are also medical applications where a VR Headset, like the Oculus Rift or HTC Vive, can be used. Currently there is a rise of virtual reality in medical applications. There are several studies in the Netherlands, ranging from the use of VR, such as in education and in pain. The medical application of Virtual Reality often requires a mobile medical set-up. Jansen Medicars has developed a special cart for it.

For several years, doctors have the opportunity to train operations using virtual simulators. The use of simulators as an application or a serious game is relatively new. Radboud University Nijmegen Medical Centre started an investigation into the use of Virtual Reality using the Oculus Rift VR goggles. This research focuses on learning in the field of Laparoscopy through a so-called Serious Game [1].

Other uses derive from the high degree of distraction by the VR headset. This appears to be very helpful in pain relief. At the burn center of the Martini Hospital VR Headsets are used to relieve pain during bandage changes. The Martini Hospital also conduct research into the application of VR in pain relief during endoscopic examinations and procedures. The first indications of this research show that there is indeed less sedation required for patients using a VR Headset.

When inserting a VR setup in pain relief, in addition to the VR Headset a computer, monitor, mouse and keyboard are required. In most cases, a mobile setup is required to be able to move the arrangement to the patient. From the viewpoint of hygiene, it is desirable to place the equipment and the cabling in a sealed housing. For the Oculus Rift special computers are available, called "Oculus Ready PCs". These computers meet the specifications that are required for the VR Headsets. The problem however, is that these are not designed for medical applications and therefore do not meet the standards for electrical safety as defined in NEN/EN/IEC60601-1 (Medical electrical equipment - Part 1: General requirements for basic safety and essential performance).

For the deployment of the Oculus Rift in a medical environment Jansen Medicars has developed a special cart. This cart is provided with a large computer compartment that -for a good accessibility of the computer- is on either side provided with a door. The cart is equipped with a medical isolation transformer, so the arrangement meets medical standard NEN/EN/IEC60601-1. The top side of the computer compartment is the worktop for the keyboard and the mouse. The display is with a VESA75/100 fixed mounted to the cart. The cart is also equipped with an ergonomic handle and 100mm wheels, of which the front two are lockable.
