Abstract: Systems and methods have been developed for implementation of a breath testing system for convenient sampling of intestinal gases exhaled from a patient's breath. This may include a system with a manifold that includes thermal regulation components, for instance thermistors and resistive heating elements, which maintain the temperature of the gases above the body temperature of the patient. In some examples, the system will determine an indication of whether a patient has SIBO by adjusting a change in exhaled hydrogen concentration by a methane level exhaled by a patient.

Abstract: A negative pressure injection device which includes a suction cup and an inner skirt that encircles an injection port and depends into the interior of the suction cup. An injection member is surrounded by and protrudes below the inner skirt. When air is drawn from the suction cup an epidermis of a patient is drawn into the suction cup until the epidermis comes into contact with the inner skirt and that portion of the injection member protruding below the inner skirt. The inner skirt provides consistent epidermis positioning. The depth of injection is consistently defined by the extent to which the injection member protrudes below the inner skirt.
