Abstract
Methods and kits for sampling mucous from within a sinus to determine if a single sample includes one or more bacterial types indicating bacterial sinusitis.
Claims22
A nasal sampling device for obtaining a sinus secretion sample from a subject's sinus, wherein the nasal sampling device includes:
- an elongate body having a distal end region that is bent relative to a proximal region by between 15 degrees and 30 degrees;
- a sample collector on a distal end of an extendable shaft, wherein the sample collector is configured to collect a sample of sinus fluid, further wherein the sample collector is housed entirely within the distal end of the elongate body in a retracted position;
- and
- a control coupled to the extendable shaft, the control having a first set point wherein the sample collector is extended distally out of a distal opening of the distal end region of the elongate body a first distance between 0.5 cm to 3 cm, the control having a second set point, wherein the sample collector is retracted and housed entirely within the distal end of the elongate body, the control having a third set point, wherein the sample collector is extended distally out of the distal opening of the distal end region of the elongate body a second distance that is greater than the first distance.
