Thermostatic massage pad
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Poor heat dissipation in the contact area between a patient's body and a mattress leads to the development of pressure ulcers, particularly in individuals with mobility challenges, such as paralyzed patients or those post-surgery, due to inadequate blood circulation and heat exchange.
Innovation Solution
A thermostatic massage pad with a thermostatic water pipe and a cooling pad, integrated with a thermoelectric cooler, water pumps, and a controller, which allows for temperature adjustment and efficient heat exchange to promote blood circulation and prevent ulceration, while a massage device with airbags provides additional comfort and tissue promotion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a patient remains in bed due to mobility challenges, then medical treatment and nursing care can be provided, but heat dissipation in the contact area deteriorates leading to pressure ulcers
Solution Approach 1:
The patent introduces a mattress as an intermediary device between the patient and the bed surface. This mattress incorporates heating elements and massage mechanisms to actively manage heat dissipation and blood circulation in the contact area, thereby preventing pressure ulcers while the patient remains in bed for medical treatment and nursing care.
Solution Approach 2:
The patent changes the thermal parameters of the mattress by incorporating heating elements that can adjust the temperature in the contact area. This allows dynamic control of heat dissipation to prevent ulceration while maintaining patient comfort and promoting blood circulation during prolonged bed rest.
2Ease of operation
If the contact area between body and mattress is improved for comfort, then patient comfort increases, but heat dissipation capability worsens due to sustained compression
Solution Approach 1:
The patent incorporates a massage mechanism that dynamically adjusts the contact pressure and stimulation in the mattress. This dynamic action promotes blood circulation and prevents sustained tissue compression, thereby maintaining both patient comfort and effective heat dissipation simultaneously.
Solution Approach 2:
The heating elements and massage mechanisms operate continuously or periodically to maintain optimal temperature and blood flow in the contact area. This continuous useful action ensures that comfort and heat dissipation are maintained throughout the patient's bed rest period, preventing the development of pressure ulcers.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The thermostatic massage pad effectively enhances heat dissipation and blood circulation, reducing the risk of pressure ulcers by integrating thermostatic and cooling functions with a massage mechanism, providing comfort and preventing tissue necrosis.
