Smart bench for ambulances and air-ambulances

The Department of Nursing of the University of Alicante has designed a platform for ambulances with the function of an electronic scale that, in addition to their current functions, provides the exact value of the patient's weight, in real time, facilitating the calculation of the precise doses of drugs, fluids, etc.

This new bench design has digital sensors that capture the patient's weight, acting as an electronic scale, neglecting the weight of the stretcher that acts as a constant.

The sensors are digital load cells that calculate the exact weight of the patient in a range of weights from 3 to 300 kilograms for paediatric to adult, excluding neonates and neonatal transported in an incubator. The cells are arranged parallel to each other along the lower side bars of the platform.

A digital transmitter interconnects the sensors with each other. It could be connected to a digital screen or an electronic device with its own software. The design of the electronic device can incorporate two versions of the screen that show the parameters calculated for each patient:

• Basic design: Bench with digital scale function, LED light display incorporated in the side of the platform and wire connection to the digital transmitter.
• Advanced design: Bench with digital scale function, connected via Bluetooth to a mobile device with touch screen and integrated software showing the exact dose of drugs, fluids or other parameters, according to the weight of the patient.

The device complies with Spanish and European legal requirements in relation to the sanitary equipment of the medical vehicles, both ambulances and helicopters, according with the European Directive and Spanish Law.

• Royal Decree 22/2014 related to the technical characteristics, the sanitary equipment and the endowment of personnel of the vehicles of sanitary transport by road.
• European Directive UNE-EN 1789:2007+A2:2015. Together with homologation technical requirements as a medical device.
• DIRECTIVE 2007/47/CE.

In this way, the initial therapeutic care of critical patients is favoured, reducing the undesirable side effects by estimating the doses of these drugs or therapies.

CURRENT STATE OF DEVELOPMENT

This smart bench for ambulances is in the development phase/design. Both, the manufacture of a prototype and its homologation are currently in process.

MAIN ADVANTAGES OF THE TECHNOLOGY AND INNOVATIVE ASPECTS

Basically, the great advantage of this new design of platform for ambulances is the exact and automated calculation of doses and parameters according to the real weight of the patient, such us:

• Dose of drugs and dilutions (for example: calculation of fibrinolytics, calculation of antidotes, dose of inotropic drugs, doses of drugs in rapid sequence of intubation, analgesics, corticosteroids, etc.).
• Dose of fluids (for example, the Parkland formula in burned patients, hypertonic saline fluid, Mannitol fluid, etc.).
• Parameters for invasive mechanical ventilation.
• The energy in joules to be administered to children, in cardiac arrest.

In addition, the device could be easily implemented into an existing element within the ambulance, letting the sanitary staff to obtain an objective knowledge of the patient’s weight.

The main innovative aspect of this invention is the incorporation of a new functionality in the form of an electronic scale for ambThe present invention relates to a platform, in land or air medical vehicles, in the field of prehospital emergencies, which functions as digital balance providing the weight of the patient calculated in real time.t would allow the exact calculation of the doses of drugs, fluids and other parameters to be administered to critical patients according to their weight.

MARKET APPLICATION

The present invention relates to a platform, in land or air medical vehicles, in the field of prehospital emergencies, which functions as digital balance providing the weight of the patient calculated in real time.

COLLABORATION SOUGHT

Companies (specially, manufacturers of benches) interested in acquiring this technology for commercial exploitation through patent licensing agreements are sought. The company should be responsible for the development of the prototype, the validation of the technology, its manufacture and introduction into the market.
