Abstract: Provided herein are intranasal fluid delivery devices and apparatus comprising a dispensing tip a shot chamber carrying a fluid, the shot chamber having a diaphragm at one end and a plunger at the other end, and an actuator connected to a push rod moveable toward the shot chamber.

Abstract: Methods and systems for a catheter access port cleaning, disinfection or sterilization device are disclosed. The catheter access port cleaning, disinfection or sterilization device may comprise, a first housing having a power source and control circuit; a second housing shaped to mate with a catheter and having a first ultra-violet light source mounted therein, the first housing wired to the second housing to power the light source. When activated, the ultra-violet light source emits ultra-violet radiation that is transmitted from the second housing to the catheter attached to a patient. In this way, the device provides an efficient system for cleaning, disinfecting or sterilizing an access port in the second housing while reducing patient infections.

Abstract: Disclosed herein, are compositions, methods, systems, and apparatus for collecting biological material from the nasal cavity of a subject or the olfactory region of a subject's nasal cavity. In some embodiments, the biological material is collected from a targeted sub-region of the nasal cavity, such as a targeted sub-region of the olfactory region, wherein such biological material is specific to the targeted sub-region. In some embodiments, the biological material collected from a targeted sub-region is preserved according to its localization. In some embodiments, the biological material comprises cerebrospinal fluid, one or more microbes of the patient's microbiome, one or more components of the patient's metabolome, one or more pathogens, and/or one or more biomarkers of interest. In some embodiments, a specific formulation is delivered to the region in the nasal cavity for facilitating biological material collection located therein.

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: Sampling systems that include an absorbent material a preservative, such as an analyte preservative, as well as related materials and methods, are disclosed.
