Medical Transportation

The level of vibrations that a patient is subjected to in an ambulance is often too high. Protection from shock relies purely on the vehicle’s suspension, which also has the job of keeping the ambulance on the road. In order to develop a smoother patient experience, it is necessary to understand the dynamics of the problem. 

Throughout the UK, specialist ambulance teams provide a critical service, transferring patients between hospitals.  For many patients, this is a highly sensitive procedure with utmost care given to minimise physical shocks and vibrations to which they are exposed.  This is particularly true for transporting neonatal babies, where the patient’s trolley is connected to the floor of the ambulance securely and rigidly.  Protection from shock relies purely on the vehicle’s suspension, which also has the job of keeping the ambulance on the road.

In order to develop a smoother patient experience, it is necessary to understand the dynamics of the problem.  The first stage of this is to measure the accelerations experienced during a typical journey and use that information to design a system that targets the shock and vibration specifically. Combining measurement and analysis capability with experience of design and practical implementation allows Xi to develop and implement test procedures to monitor the vibration dynamics typically experienced.  This analysis informed the design of a system which could be implemented into existing systems providing isolation for patients whilst maintaining the practicality of maintenance.
