AI Technical Summary
Surgical position errors and hypothermia-related hazards during operations lead to significant adverse events and compensation claims, with existing technologies failing to provide real-time monitoring and prevention mechanisms.
An Arduino-based embedded system with pressure and temperature sensors provides real-time visualization and alarms to prevent artery and nerve compression, and hypothermia by detecting and alerting caregivers when thresholds are exceeded.
Reduces the risk of surgical complications by ensuring accurate positioning and maintaining optimal body temperature, thereby minimizing adverse events and associated costs.

Abstract
Description
Title of the invention: Tools for avoiding position errors, artery and nerve compression, and hypothermia control. Context :
[0001] In France, compensation for medical errors reaches an average of 850,000,000 euros with 90,000 serious adverse events including death.
[0002] Studies on surgical errors demonstrate, on a selected population sample, that position errors come second in serious adverse surgical events, including: death, paralysis, blindness, etc. with ± 25% of total serious adverse events, i.e. more than 100,000,000 euros in compensation out of the 830,000,000 euros in total annual compensation in France (insurer data). The tool:
[0003] The tool is at the seed stage and is an artmega arduino type embedded system, having as pressure sensor RP-C10-ST detection 20mg minimum, and temperature sensors TO92.
[0004] A graphic system allows real-time visualization of the pressure exerted on the different organs and the overall temperature under the operating field to avoid hazards linked to hypothermia.
[0005] In the event of exceeding a threshold of temporal or instantaneous damage for an organ, the system activates an alarm and a visual to alert the caregiver (ibode / iade) of the danger of the position for the patient, or of the danger of hypothermia. Recipient:
[0006] the ibode, assistant or the surgeon, or the iade near the respirator.
[0007] This choice will be up to the authorized personnel, the iade being able to be overloaded with regard to these multiple controls on the respirator, and the ibode having to be available for the surgeon.
[0008] The circulating nurse may be targeted, however, he may be outside the operating room at the time of an incident. Pressure sensor operation
[0009] Examples of surgical incidents show that optical (eye) compression has caused permanent blindness linked to poor head position on the operating bed.
[0010] The same applies to bad positions which have led to permanent motor disability.
[0011] In fact, this simple and low-cost system, less than 50 euros, makes it possible to measure the forces exerted on certain organs.
[0012] With a diameter of 20 mm without any risk of electrocution, it is fixed by a blindfold or other on the patient's eyes, brachial artery or other...
[0013] the system is connected to a computer equipped with a real-time graphical visualization interface.
[0014] When the pressure exceeds a maximum threshold, the system launches a visual and audible alarm and may possibly cut off various other systems in the operating room (external trigger).
[0015] It is also possible to have a scale or a time pressure threshold, clearly we can say that a pressure for example of 500 grams cannot exceed a time of application on an organ, for example eye not exceeding a duration of 20 seconds, beyond this limit the system launches the alarms. How hypothermia sensors work:
[0016] The T092 type sensors are placed via an electrode type glue system on the operating and patient fields.
[0017] Time values are visible in real time via the graphical interface.
[0018] When the temperature falls below a maximum threshold or the integrated time measurement exposes the patient to after-effects, the system triggers alarms. The latter could even control the patient heating system to autonomously increase the temperature under the operating field to fall below the hypothermia limit threshold. 3D viewing screen:
[0019] The interface includes the body, the visualization of pressures and temperature.
[0020] In the case of excessive values, a different alarm message for temperatures and pressure appears, likewise, the color of the measuring point concerned changes to red.
[0021] Excessive values will flash, a red post process will activate and an audible alarm will sound.
[0022] If necessary, the PC will return a fault overlock trigger in UDP or serial. Electronic architecture:
[0023] The sensors are connected to the standard inputs of an Arduino uno type card, and positioned on the patient for the force sensors and under the operating field for the temperature sensors.
[0024] The system communicates in Udp with a computer, in a later seed phase everything will be Bluetooth or wifi.
[0025] be sent by the card or a udp signal from the 3d visualization computer., or screen...
