2 Team Members: Ann Sagstetter, Kelvin Ng, Timothy Balgemann, Angwei Law, Padraic Casserly Client: Dr Julie Kessel, Dept of Pediatrics Advisor: Prof Brenda Ogle, Dept of BME Umbilical Vein Catheterization Training Model

3 Outline of Presentation Problem Statement current methods need improvement Background Information umbilical anatomy & catheterization, NRP training, current products Client’s Expectations: The PDS Design Components architecture, stabilization, materials Brainstorming models 1, 2, 3 Design Matrix Future Work References & Questions - CONFIDENTIAL - http://www.ovulation-calculator.com/cord.gif

4 Problem Statement - CONFIDENTIAL - To construct a model optimized in the following ways for use in the umbilical vein catheterization training program: firmly stabilize a fresh umbilical cord accurately mimic an infant’s abdomen external texture internal structure http://www.geocities.com/placenta_rb/Fig42.jpg

5 Background Information - CONFIDENTIAL - The Anatomy of the Umbilical System http://www.anatomyatlases.org/MicroscopicAnatomy/Section13/Plate13261.shtml

6 http://www.medicalook.com/systems_images/Fetal_circulation.jpg Fetal Circulation

7 Background Information - CONFIDENTIAL - Umbilical Vein (UV) Catheterization 3.5-F or 5-F catheter is commonly used 1 F = 1/3 mm  depth of insertion depends on urgency may be performed up to 7 days after birth http://www.aap.org/nrp/images_z_nu/tnr5_f6-2_veinousumbillical.jpg

8 UV Catheterization Training Background Information - CONFIDENTIAL -

9 Background Information - CONFIDENTIAL - Current Products http://www.cfpc.ca/cfp/2003/Jan/vol49-jan- clinical-2_fr.asp http://www.laerdal.com.au/document.asp?subnodeid=8619562

10 Background Information - CONFIDENTIAL - In comparison to reality… http://www.babylink.info/edinburgh/Images/UAC.jpg

11 Client’s Expectations: The PDS Use real, fresh umbilical cords “Umbilicus” must stabilize the cord Mimic anatomical course of UV Mimic texture of abdomen Include a blood reservoir Disposable or sterilizable materials preferred - CONFIDENTIAL -

12 Design Components - CONFIDENTIAL - 1. Architecture general size and structure blood reservoir anatomical course 2. Stabilization fixing the cord to the model no inward or outward slipping 3. Materials texture mimicry disposable / sterilizable

13 Brainstorming - CONFIDENTIAL - Model 1 (Salad Bowl)

14 Brainstorming - CONFIDENTIAL - Model 2 (Pommel Horse)

15 Brainstorming - CONFIDENTIAL - Model 3 (Gel Cushion)

16 Design Matrix - CONFIDENTIAL -

17 Brainstorming - CONFIDENTIAL - Stabilization Clamp approach Adhesive approach Materials Gelatin Foam Silicone

18 Future Work - CONFIDENTIAL - Experiments on Materials texture of foam versus gelatin adhesion to umbilical cord sterilizability / disposability Stabilizing Structures depend on chosen material adaptable to various cord sizes keep cord intact
