Title: Innovations by Charles N McKinnon, Jr.
Introduction
Charles N McKinnon, Jr. is a notable inventor based in Laguna Niguel, CA (US). He has made significant contributions to the field of medical technology, particularly in needleless injection systems. With a total of 6 patents, his work has advanced the way medications are administered, providing safer and more efficient methods for patients.
Latest Patents
One of his latest patents is the "Needleless hypodermic injection methods and device." This innovative device features an initiator valve that controls the flow of compressed gas into a reservoir. A poppet valve connects to the reservoir and regulates the gas flow, while a clamp piston driven by gas pressure causes jaws to clamp onto a plunger extending into an ampule. When the reservoir pressure reaches the cracking pressure of the poppet valve, gas rushes through, forcing a drive piston forward and discharging a jet of injectant through the patient's skin. This method utilizes specific parameters to enhance the effectiveness of needleless injections.
Another significant invention is the "Electrically powered jet injector." This device generates a high initial pressure pulse to pierce the skin, followed by a lower delivery pressure to complete the injection. A microprocessor controls the speed and direction of the electric motor, making it particularly useful for subcutaneous injections, such as insulin for diabetes treatment.
