Pressure management warming headrest
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure management devices for surgical headrests are inadequate for patients in supine and side-laying positions, and they fail to effectively warm the patient's head during surgery, leading to heat loss and inefficient use of storage space.
Innovation Solution
A pressure management warming headrest that integrates a spacer layer, a heating layer with a self-regulating PTC heating element, and a pressure management layer of bonded foam layers, designed to accommodate various patient sizes and positions, with a compact storage option.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing pressure management devices with round holes or recesses are used, then pressure management for the occiput is provided, but the device is not well suited to the anatomy of the human head in supine or side-laying positions
Solution Approach 1:
The headrest device incorporates a contoured shape with a depression that dynamically adapts to different head positions and anatomies. The depression is configured to receive the occiput when the patient is in a supine position, and the overall contoured design allows the device to accommodate both supine and side-laying positions, providing reliable pressure management across multiple anatomical configurations.
2Reliability
If foam-based pressure management devices are used, then pressure management is provided, but the devices are bulky and take up considerable storage space
Solution Approach 1:
The heating element is nested within the foam structure of the headrest device. The heating element can be positioned within a cavity or channel formed in the foam, allowing the thermal management component to be integrated without significantly increasing the external dimensions or storage volume of the device while maintaining the pressure management function of the foam.
3Ease of operation
If the patient's head is left uncovered during surgery, then surgical access is improved, but significant heat loss occurs from the head
Solution Approach 1:
The device merges pressure management and thermal management functions into a single integrated headrest system. The foam structure provides pressure relief while the integrated heating element compensates for heat loss, allowing the patient's head to remain covered and protected without compromising surgical access or thermal stability.
Solution Approach 2:
The heating element utilizes electrical energy conversion to thermal energy through resistive heating. The heating element converts electrical power into thermal energy to warm the patient's head, counteracting heat loss during surgery without requiring physical contact or complex thermal transfer mechanisms.
