Cardiac surgeons require a great deal of imagery before they operate on a child’s heart. They need to be able to visualize the arrangement of the heart’s components and defects they want to correct before they embark on surgery. For decades, visualization imagery was provided by MRIs and CT scans. Now those imaging technologies are starting points for fully rendered 3D models of the heart, models the surgeons can touch and analyze from all angles before they enter the operating suite.

In a process jointly developed with the Images Processing Applications Lab at Arizona State University, the nationally recognized Cardiac 3D Print Lab at Heart Center at Phoenix Children’s Hospital uses the images produced by MRIs and CT scans to print accurate 3D models of patients’ hearts. In addition to providing crucial information to surgeons, the accuracy of the models improves communication with families, who may be struggling to understand their child’s condition.

Leading-edge activities, however, aren’t always free of workplace hazards. Production processes in the Cardiac 3D Print Lab entail the use of enamels, epoxies, and adhesives. Proper safeguards for these processes include adequate ventilation.

Testimonial from a Team Member at the Cardiac 3D Print Lab

Justin Ryan, a team member from the Cardiac 3D Print Lab, reviewed our ductless spray hood and python portable fume extractor after using it in the lab. He is very satisfied with the safety protection our products provide and supplied the following review.

Ductless Fume Hood/Spray Hood

3D printed and color coded model hearts displayed in Sentry Air's Model 330 Ductless Spray Hood, installed in the Cardiac 3D Print Lab to capture aerosol sprays. No remodeling or additional ductwork was required.

The lab uses a 650 zPrinter (Z Corporation), a full-color printer, that prints a gypsum powder with ink binding agents. Printer models are coated in the fume hood to make them stronger. They also use the fume hood to mix epoxies and silicones for other medical applications.

Phoenix Children’s Hospital houses the Cardiac 3D Print Lab which produces 3D printed models for surgical planning, family consultation, and medical education in addition to innovating research. Some research applications require epoxies, enamels, plastics, silicones, and dissolving agents. In order to achieve a safe environment without slowing down momentum in research, we purchased the SS-330-DSH. The ductless fume hood was quickly integrated into the laboratory without significant infrastructure change, which would have been very challenging in a hospital. The hood allows us to effortlessly move models from the 3D printer to coating or casting processes that need ventilation.

Portable Fume Extractor

Sentry Air's Model 400 Floor Sentry with a python hose. The facility also purchased a Model 400 Python Portable Fume Extractor (SS-400-PYT) for various fume extraction uses in the lab. The Cardiac 3D Print Lab uses a Model 400 Floor Sentry with a python hose like the unit shown in this photo to capture 3D printing particles. Like the Model 330 spray hood discussed above, the Model 400 traps respiratory hazards without expensive facility updates. Heavy-duty casters and use of standard 115 electrical outlets make the Model 400 a productive asset in innovative workplaces.

In addition, we recognized the capabilities of the ductless technology and purchased the SS-400-PYT. The Portable Floor Sentry is able to be pushed to the area in the lab that needs it the most. It is easy to utilize the Floor Sentry for ventilating our vacuum chambers one moment then to the modified printer with experimental materials.

Overall Phoenix Children’s Hospital – Cardiac 3D Print Lab is very satisfied with our product due to the easy integration into the workflow. To close out the review Justin Ryan added:

Both Sentry units have been integrated into our lab and have been critical to its workflow.
