Abstract:
1. A method of using a pressure detection device comprising: obtaining, by a processing device, a first pressure at a first time and a second pressure at a second time in real time via a pressure transducer, wherein the first pressure and the second pressure each, individually, represent a pressure of an area at a tip of a needle, and wherein the first time and the second time occur while inserting the needle into a joint cavity; determining, by the processing device, a pressure difference between the first pressure and the second pressure, wherein the pressure difference represents a difference between a pressure in a cavity and atmospheric pressure; determining, by the processing device, a time difference between the first time and the second time; performing, by the processing device, a first determination to determine whether the pressure difference divided by the time difference is less than a slope threshold; and providing an indication to inject a medication.
