<h1 class="text-left"><i>Objective</i></h1>
<p class="lead text-left font-19">
<br>To design and build a working prototype of an intervention device tester. The device consists of a test bed, support table, and force measurement unit. The device was built by two teams of four students with a medical device industry client. My team completed the test bed and table while the other group focused on the force measurement unit. The prototype was completed as a part of the McGill University Mechanical Engineering Capstone Project.
</p>
<p class="lead text-left font-19">
The device is used to test axial forces exherted on intravenous catheters after insertion into different circulatory system models for simulation. The test bed maintains a water temperature at 37°C to approximate human body temperature.

<h1 class="text-left"><i>What is a catheter based intervention device?</i></h1>
<p class="lead text-left font-19">
<br>A catheter based intervention device is a device designed to be brought subcutaneously (beneath the skin) through the circulatory system to a target treatment site. A primary benefit of catheter based interventions is the reduced invasiveness of the procedure when compared to direct surgery.
</p>
</div>
<div class="col-md-4">
<h1 class="text-left"><i>Why is an intervention device tester necessary?</i></h1>
<p class="lead text-left font-19">
<br>A catheter based device must be stiff enough so that it can be pushed but also flexible so that it may navigate without causing damage to the blood vessels. The intervention device tester (IDT) advances and retracts a catheter through a model of a circulatory system, indirectly recording the forces exerted on the models walls by measuring axial forces at the base of the catheter.

<h1 class="text-left"><i>Waterbath</i></h1>
<p class="lead text-left font-19">
<br>The water bath is made from ½” acrylic which allows the tests to be fully observed and has reasonable thermal insulation. The strength and impact resistance was adequate for a clean lab environment. The bath was designed by the students but professionally built at <em>Aquastyle Design<em>.

<h1 class="text-left"><i>Submersed Model Platform</i></h1>
<p class="lead text-left font-19">
<br>The simulation is performed with a variety of circulatory models of different sizes. The platform height can be adjusted with respect to the insertion point to accomodate for different size models. The platform is perforated with ¼” holes to both allow flow and to provide a plethora of model fixation points. The platform height is controlled by twin linear actuators adjusted by potentiometers with millimeter accuracy.

<h1 class="text-left"><i>Insertion Port</i></h1>
<p class="lead text-left font-19">
<br>The test models are desinged for zero-angle insertion. Therefore, the catheter must enter below the waterline of the test bed. A modular design was produced to accommodate different catheter sizes and insertion methods. The modularity comes in the form of a secondary plate which can be removed and altered. This allows for easy replacement and low cost modification if a catheter has unique introduction requirements.
