Stethoscope Simulator

  HomeGrown Solution Number: 287
Identification of the Problem
Auscultation with stethoscope is an indispensable tool for optimal management of cardiopulmonary patients. However, the acquisition of sufficient training in cardiopulmonary auscultation is not straightforward during undergraduate training, because of the technical and ethical problems and simulation is essential for improving both basic and advanced skills in a safe environment. Moreover, the use of commercial stethoscope simulators is limited by their high cost. In order to overcome these limitations, I realized the need for a low-cost stethoscope simulator to acquire and maintain the basic skill to cardiopulmonary patients.
Unique Idea
The idea is to create a low cost stethoscope simulator that can be homemade using cheap available technology, especially in low or limited resources situations. This simulator will enhance the fidelity when used with SP. This submission is different from other submission on site.
Describe the development and use of locally made inexpensive stethoscope simulator developed by respiratory medicine physician in the department of respiratory care, Almaarefa Colleges, Riyadh, Saudi Arabia.
1. Normal Stethoscope
2. Commercial One ear Bluetooth Headset
3. Cutter
4. Glue
5. Personal computer with MS power-point application and should support Bluetooth head sets
6. Recorded sound tracts of cardiopulmonary sounds in MP3 format,each tract should be 30 -60 seconds in duration (shown in attached table)
Steps to Creating the Solution
1. A 3 millimeters hole is formed in the stethoscope at the site of junction of the 2 ear piece tubes
2. The ear piece of the Bluetooth headset is inserted and glued in the 3 millimeter opening of the stethoscope and now the hardware of the simulator is ready.
3. In the PC a single slide PowerPoint presentation is made and designed to be the human interface. In the slide all all the desired sound are listed and a link is created to the corresponding sound tract in the PC folder so that when a sound icon is clicked the sound tract is played.
4. Set up and connect the Bluetooth device with PC following the instructions of the Bluetooth device manufacturer.
