Enhanced Clinical-Realism In Medical Simulation TrainingStandardised Internal Video Projection Virtual Patient

Problem

Discussions with Dr Michal Wozniak revealed that most manikins used in medical training scenarios were based on young fit males…

Most medical manikins are based on representations of young, physically fit, Eurasian adults.

This is not typical of most medical diagnostic situations world-wide…

They often neglect the infinite variation generated by age, gender, race and size.

body weight and a myriad of other factors, can potentially play a significant role in diagnostic procedures.

Immersive learning environments require changing the appearance of manikins. This can be problematic and cannot transform over time or in response to treatment.

considerable amount of time and effort was spent undertaking Moulage (applying mock injuries for the purpose of training).

Solution?

Concept

The Projection Mapping Medical Simulation Manikin Concept, is a proposed medical training tool that uses the technology to project three dimensional static or dynamic visual textures (can be physically recorded or virtually modelled), simulating patient disease, disorder or trauma, onto the surface of a patient manikin.

The application of this technology involves combining the immersive experience of Projection Mapping (without the need to wear cumbersome, inconvenient and expensive VR goggles/headgear) with a physical clinical environment.

Concept

The digital technology can display dynamic and interactive three dimensional textures, onto a 3D projection surface (manikin).

This technology potentially could also be used to show accelerated patient deterioration or patient improvement, in response to medical intervention.

Or create an interactive three dimensional “smart” surface, which can describe medical procedures, internal features, external aspects etc.

Projection Mapping Patient Simulator Content:

The 3D “projection surfaces” will be developed to replicate life-like human forms, drawing on an almost infinite range of computer generated patent physiological and medical conditions via textures. Mechanisms of diagnostic procedure which will be simulated include:

On the Face: unilateral facial droop (facial palsy) from stroke. rashes. trauma (bruising, wounds). pale (anaemia), ashen. bilateral subconjunctival haemorrhage

Projection Mapping Patient Simulator Content:

The 3D “projection surfaces” will be developed to replicate life-like human forms, drawing on an almost infinite range of computer generated patent physiological and medical conditions via textures. Mechanisms of diagnostic procedure which will be simulated include:

Eyes: unilateral and bilateral changes to pupil size. eyelids that open and close. unilateral eyelid drooping due to facial palsy. Nystagmus. orbital and peri-orbital trauma and infection. unilateral or bilateral red eye (conjunctivitis).

Projection Mapping Patient Simulator Content:

The 3D “projection surfaces” will be developed to replicate life-like human forms, drawing on an almost infinite range of computer generated patent physiological and medical conditions via textures. Mechanisms of diagnostic procedure which will be simulated include:

Projection Mapping Patient Simulator Content:

The 3D “projection surfaces” will be developed to replicate life-like human forms, drawing on an almost infinite range of computer generated patent physiological and medical conditions via textures. Mechanisms of diagnostic procedure which will be simulated include:

Mouth: pale/white/ashen. blue (central cyanosis). drooping one side of mouth (part of facial palsy).

Projection Mapping Patient Simulator Content:

The 3D “projection surfaces” will be developed to replicate life-like human forms, drawing on an almost infinite range of computer generated patent physiological and medical conditions via textures. Mechanisms of diagnostic procedure which will be simulated include:

Projection Mapping Patient Simulator Content:

The 3D “projection surfaces” will be developed to replicate life-like human forms, drawing on an almost infinite range of computer generated patent physiological and medical conditions via textures. Mechanisms of diagnostic procedure which will be simulated include:

Torso and Limbs: rashes such as anaphylaxis (urticarial or ‘hives’) and infectious rashes (meningococcus, shingles, chicken

pox). lack of chest movement on one side to indicate lack of function (e.g. pneumothorax or haemothorax). trauma (bruising, penetrating wound). in-drawing of muscles between ribs during difficult breathing (intercostal recession). abdominal trauma/bruising. abdominal/pelvic pathology.
