The CDT is a cervical dilation training aid. It is a 3D printed set of training aids to systematically train your hand muscle memory to set diameters of circles that correlate directly to the 3 stages of labor as it pertains to dilation of the cervix.
Stage 1 is shown in white and features 1, 2, and 3 cm gauge holes that are built into the lid that snaps onto the case.
Stage 2 is shown in pink and features 4, 5, 6, and 7 cm gauge rings.
Stage 3 is shown in purple and features 8 and 9 cm gauge rings, as well as the 10 cm dilation gauge that is built into the case that holds all of the training aids. This set doesn't absorb liquids like fabric or wood. These can be cleaned in warm water with antibacterial soap and air dried. They also fit nicely into most scrubs pockets. 
 
Imitation is the sincerest form of flattery, but let's get one thing clear. You're trying to develop muscle memory skills to serve patients and deliver healthy babies to the best of your abilities. Solid tools that do not flex, give you true and accurate measurements to build the skills that are required. These are all unique designs that I created and own under Dragon Designs and they distributed through Dragon Tactical and items will bear my DT3D logo. 
 
The standard color arrangement mentioned in the above description is what I keep stock levels on, but custom colors can be requested. Custom colors may slightly increase cost and will increase the lead time.
