Is the diaphragm paediatric? Is a rim available with the diaphragm?

I am afraid the diaphragm I bought was cardiologic but all varieties of spare parts for all types of stethoscope original are available on Amazon though you have to furnish an ID proof.

Is the rim for the adult or Pediatric side diaphragm?

Different as paediatric hearts are smaller

Can fit the diaphragm on our own?

Yes you can. It is very simple. Just follow the instructions on the packet.
