Amazon in India will sell you a pretty reasonable stethoscope for for $3.

Assuming the usual Amazon, distributor and retailer markups, these probably cost around 50 cents to make in China.

Many poor countries are perfectly capable of manufacturing their own medical equipment

Background: I have worked in hospitals in Bihar & Vellore Tamilnadu, and have university mates, friends and family who worked in hospitals in Mizoram, PNG, Libya, Nepal, Uganda and even South Sudan.

Even the doctors who worked in South Sudan had no difficulty sourcing basic equipment. They did however, have enormous trouble sourcing funding and trained personnel who were willing to work in a potentially lethal situation.
