Title: Helen Frances Routh: Innovator in Medical Ultrasound Technology
Introduction
Helen Frances Routh is a distinguished inventor based in Seattle, WA, known for her significant contributions to medical technology. With a total of eight patents to her name, she has made remarkable advancements in the field of ultrasound diagnostics and therapy.
Latest Patents
One of her latest patents is a method and apparatus for guidance and application of high-intensity focused ultrasound (HIFU) for controlling bleeding due to severed limbs. This innovative ultrasonic diagnostic and therapy system is designed to stop the bleeding of severely damaged blood vessels or vessels severed in limb amputations. The system includes a cuff attached to the stump of the severed limb, which contains a diagnostic transducer array and a HIFU transducer. The diagnostic transducer surveys the tissue of the severed limb, searching for a Doppler flow signal. Upon detecting a Doppler flow signal, the system determines the range and coordinates of the sample volume where the flow was detected, as well as the flow velocity. This information is then supplied to a HIFU therapy transducer controller, which directs the HIFU transducer to transmit focused ultrasound to the sample volume of the flow locus, effectively heating and coagulating blood in the severed vessel to stem the bleeding.
Career Highlights
Throughout her career, Helen has worked with notable companies such as Advanced Technology Laboratories, Inc. and Koninklijke Philips Corporation N.V. Her work has significantly impacted the medical field, particularly in improving patient outcomes during critical situations involving severe bleeding.
Collaborations
Helen has collaborated with esteemed colleagues, including Roy B. Peterson and Marshall T. Robinson, contributing to the advancement of ultrasound technology and its applications in medicine.
Conclusion
Helen Frances Routh's innovative work in ultrasound technology has paved the way for new methods in medical treatment, particularly in emergency care. Her contributions continue to influence the field and improve the lives of many patients.
