BOYD Provides a Simple, Effective and Compact Cooling Solution for Portable Cold Therapy Medical Devices
Introduction
Aqueduct Medical is a leading producer of cooling system therapy
devices for post-operative care for facial plastic surgery. Their
cooling system circulates cooled water through their patented masques
and vests to reduce pain, swelling, bruising, and downtime for patients
in a safe and controlled manner.
Challenge
●These portable cold therapy medical devices must be portable, light, easy to use, and affordable while keeping their cooling and operating temperatures at very specific levels for patient comfort and safety.
●While creating the prototype for their device, Aqueduct Medical sought the expertise of BOYD, to aid in designing and optimizing the heat dissipation assembly.
●The prototype had very specific design constraints such as being easy to use and unobtrusive in a patient’s home. It also had to be affordable while maintaining proper temperatures to deliver the maximum therapeutic use.
●Noise, weight, power consumption, and cost all need to be kept carefully regimented as well as temperature. The industrial design also had to conform well to how the prototype worked and operated.
Solution
Boyd engineered and optimized the heat dissipation assembly for
prototyping. The cooling solution was designed with thermoelectric
modules placed on a cold plate and an active cooling consisting of heat
sinks and a fan while complying with the design constraints of:
• Less than $35 production cost for the cooling solution
• 28℃ Ambient Temperature
• Noise
• Power Supply <220W, 12V DC
Fluid Flow
• Tap water, Distilled water, or Saline.
• Target flow rate < 0.8lpm to enter a liquid cold plate
• Liquid enters the cold plate at a maximum of 7℃
• 60W must be removed from the liquid entering the cold plate
During
the design and optimization process, the cost for a mass production
version of the cooling solution (heat sink, cold plates) was estimated.
Boyd
managed to keep the cost close to the targeted price, the acoustics
below the target, and provide a simple, effective, and compact cooling
solution.
Implementation
The device is used for medical and therapeutic purposes to reduce swelling and ease aches and pains. This can be utilized in both inpatients and the comfort of the users’ homes. Boyd designed the cooling solution to make this product work as intended and to the specifications of Aqueduct Medical.
