SurgiLink

Read full description

This app is designed by and for medical devices sales professionals. The base function of the app is a calendar but one that is designed for the unique workflow of surgical support. You are able to pre-load facilities, surgeons and frequently used surgical trays to be added to a calendar event/surgery. You can also add trays case by case if you prefer. Once you’ve added your trays, you can update their current location so the whole team knows where they are. Each individual calendar event also keeps track of whether the trays should be held or opened, and whether or not they’ve been checked into the hospital.

I want to hear from you to make the app as useful as it can be. Thank you!
