Sensor-Integrated CPR Restraints for Stable Skin Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanical CPR devices face challenges in maintaining consistent and reliable monitoring of physiological parameters due to sensors losing contact with the patient's skin during compressions, and the need for rescuers to divert attention from CPR to manage multiple tasks.
Innovation Solution
Incorporating sensors into wrist and neck restraints that securely hold the patient's body in place, ensuring consistent contact with the skin and providing real-time monitoring, with feedback for adjusting CPR device operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are worn on patients' bodies for monitoring physiological parameters, then real-time health status information is obtained, but sensors easily lose contact with the skin during CPR compressions
Solution Approach 1:
The patent combines the sensor with the restraint system into a single integrated unit. The sensor is embedded in or attached to the restraint that secures the patient's torso to the CPR device, ensuring the sensor remains in constant contact with the patient's skin throughout the CPR process without requiring separate sensor placement.
Solution Approach 2:
The restraint acts as an intermediary between the sensor and the patient's skin. By positioning the sensor through the restraint structure, the system ensures stable contact while the restraint performs its primary function of securing the patient during compressions.
2Productivity
If manual CPR is performed by medical personnel, then compressions can be adjusted in real-time, but personnel must divert mental attention from other tasks to maintain proper compression timing and depth
Solution Approach 1:
The mechanical CPR device performs compressions autonomously without requiring continuous human intervention. Once programmed with the desired compression parameters, the device self-regulates the compression timing and depth, freeing medical personnel to focus on other critical patient care tasks while maintaining consistent compression quality.
Solution Approach 2:
The integrated sensor provides real-time feedback on the patient's physiological status to the mechanical CPR device, enabling automatic adjustments to compression parameters as needed, thereby maintaining reliable compression consistency without requiring rescuer attention.
3Object-affected harmful factors
If restraints are used to secure patients during mechanical CPR, then patient safety is improved by keeping hands and arms away from compression mechanism, but additional monitoring equipment increases device complexity
Solution Approach 1:
The sensor is integrated into the restraint structure itself, combining the safety function of the restraint with the monitoring function of the sensor. This eliminates the need for separate monitoring equipment and reduces overall device complexity while maintaining patient safety.

AI summary
A restraint configured to secure a patient to a mechanical cardiopulmonary resuscitation (“CPR”) device. The restraint includes a physiological sensor configured to detect a physiological parameter of the patient and to output a signal indicative of a value of the physiological parameter.
