He holds 2 patents that showcase his innovative approach to improving blood sampling methods. His work is characterized by a focus on user-friendly designs that enhance the efficiency of medical procedures.
Latest Patents
Couchman's latest patent is a closed one-handed blood sampling system. This innovative device features a one-handed blood sampling reservoir designed for an infusion line. The configuration allows discard fluid to be drawn into the reservoir and then returned to the patient using two squeezing motions. Both the drawing and returning steps are performed by squeezing two of the finger grips provided on the reservoir. The design may include a bracket for one-handed operation in either hand-held or pole-mounted configurations. Alternatively, the reservoir and finger grips can be formed by telescoped inner and outer housings without a bracket. The reservoir includes a syringe-like body that forms a chamber and a plunger/piston assembly that is reciprocal within it to vary the chamber's volume. A narrow gap in the chamber is open to both inlet and outlet ports when the piston is fully seated, ensuring a consistent and minimum flush volume. The piston may be spring-loaded against the syringe body, simplifying manufacturing by reducing the number of close tolerance parts required. The reservoir is ideally placed within an infusion line that contains a pressure transducer, and the spring-loaded piston can be adjusted to vary the dynamic response of the fluid pressure system.
