Abstract
Apparatuses for sampling mucous from within a sinus to determine if a single sample includes one or more bacterial types indicating bacterial sinusitis comprising an indicator to guide the angle at which a user inserts the apparatus relative to the patient.
Claims20
A nasal sampling device for obtaining a sinus secretion sample from a subject's sinus, the nasal sampling device comprising:
- a proximal handle configured to be held in a human hand;
- an elongate body extending distally from the proximal handle and having a distal portion that is configured to be inserted into a nare of a patient;
- a sample collector on a distal end of an extendable shaft configured to collect a sample of sinus fluid for diagnostic testing, further wherein the sample collector is housed entirely within the distal portion of the elongate body in a retracted position;
- and
- a control on the extendable shaft and visible through the elongate body, the control having a first position wherein the sample collector is extended distally out of a distal opening of the distal portion of the elongate body a first distance between 0.2 cm to 3 cm, the control having a second position, wherein the sample collector is housed entirely within the distal end of the elongate body in the retracted position, the control having a third position, wherein the sample collector is extended distally out of the distal opening of the distal portion of the elongate body a second distance that is greater than the first distance.
A nasal sampling device for obtaining a sinus secretion sample from a subject's sinus, the nasal sampling device comprising:
- a proximal handle configured to be gripped with a human hand;
- a body coupled to the proximal handle;
- a distal portion of the body configured to be inserted into a nare of a patient;
- a cover configured to cover the distal portion;
- a sample collector configured to collect a sample of sinus fluid for later diagnostic testing, the sample collector having a retracted position within the distal portion and an advanced position extending distally past a distal end of the distal portion and the cover, wherein the cover is configured to prevent contamination of the sample collector in the retracted position;
- an actuator configured to advance the sample collector to the advanced position and to retract the sample collector to the retracted position;
- and
- an indicator on or adjacent to the proximal handle extending from a long axis of the device at an angle of between 33 and 37 degrees, wherein the indicator is configured to be oriented perpendicular to a frontal plane of the patient's body.
A nasal sampling device for obtaining a sinus secretion sample from a subject's sinus, the nasal sampling device comprising:
- a proximal handle configured to be held in a human hand;
- an elongate body extending distally from the proximal handle and having a distal cover portion that is configured to be inserted into a nare of a patient;
- a sample collector on a distal end of an extendable shaft configured to collect a sample of sinus fluid for diagnostic testing, further wherein the sample collector is housed entirely within the distal cover portion of the elongate body in a retracted position;
- and
- a control on the extendable shaft, the control having a first position wherein the sample collector is extended distally out of the distal cover portion of the elongate body a first distance between 0.5 cm to 3 cm, the control having a second position, wherein the sample collector is housed entirely within the distal cover portion of the elongate body in the retracted position, the control having a third position, wherein the sample collector is extended distally out of the distal cover portion of the elongate body a second distance that is greater than the first distance.
