WEARABLE SUCTION ASPIRATOR FOR NASAL, ORAL AND TRACHEOSTOMY AIRWAY SECRETIONS
A wearable suction catheter that can be used without clinician control. The suction catheter attaches on or near the patient with a patient interface configured for the shape of the nose, mouth or tracheostomy tube. The patient interface includes at least two radial duct openings and each end of the interface is connected to airway tubing ending in a wye. The wye end of the catheter includes a cleaning access port and is attached to a suction source that provides continuous or intermittent suction.
1 . A wearable suction catheter, comprising:
a plastic patient aspirator interface having a tubular body and at least two aspiration openings;
a first airway tube and a second airway tube, both connected endwise to opposite ends of the tubular body; and
a wye conduit having a conduit inlet and first and second conduit branches, wherein the first conduit branch is connected to the first airway tube and the second conduit branch is connected to the second airway tube, and the conduit inlet is configured for connection to a vacuum source.
2 . The wearable suction catheter of claim 1 , wherein the tubular body is configured for attachment to a patient's mouth such that the at least two aspiration openings are disposed proximate to either side of the patient's mouth.
3 . The wearable suction catheter of claim 2 , the patient aspirator interface further having an oral aspiration tube configured for insertion into one side of the patient's mouth.
4 . The wearable suction catheter of claim 3 , the patient aspirator interface having two oral aspiration tubes configured for insertion into both sides of the patient's mouth.
5 . The wearable suction catheter of claim 1 , wherein the tubular body is configured for attachment to a patient's nares such that the at least two aspiration openings are disposed proximate to either side of the patient's nares.
6 . The wearable suction catheter of claim 4 , the patient aspirator interface further having two nasal aspiration tubes configured for insertion into the patient's nares.
7 . The wearable suction catheter of claim 1 , wherein the tubular body is shaped as a torus and configured for disposal around a patient's tracheostomy tube and has a latitudinal curvature configured to match a patient's neck proximate to the tracheostomy tube, such that the aspiration openings are disposed proximate to the tracheostomy tube.
8 . The wearable suction catheter of claim 7 , the patient aspirator interface having four aspiration openings.
9 . The wearable suction catheter of claim 1 , further comprising a cleaning port in the wye conduit disposed between the conduit inlet and the conduit branches.
10 . The wearable suction catheter of claim 9 , further comprising a cap on the cleaning port configured for selectively opening the cleaning port.
11 . A wearable suction catheter, comprising:
a plastic patient aspirator interface having a tubular body and at least two aspiration openings, wherein the tubular body is configured for attachment to a patient's mouth or nares such that the at least two aspiration openings are disposed proximate to either side of the patient's mouth or nares;
a first airway tube and a second airway tube, both connected endwise to opposite ends of the tubular body; and
a wye conduit having a conduit inlet and first and second conduit branches, wherein the first conduit branch is connected to the first airway tube and the second conduit branch is connected to the second airway tube, and the conduit inlet is configured for connection to a vacuum source.
12 . The wearable suction catheter of claim 11 , the patient aspirator interface further having two oral aspiration tubes configured for insertion into both sides of the patient's mouth or two nasal aspiration tubes configured for insertion into the patient's nares.
13 . The wearable suction catheter of claim 11 , further comprising a cleaning port in the wye conduit disposed between the conduit inlet and the conduit branches.
14 . The wearable suction catheter of claim 13 , further comprising a cap on the cleaning port configured for selectively opening the cleaning port.
15 . A wearable suction catheter, comprising:
a plastic patient aspirator interface having a tubular body and at least four aspiration openings, wherein the tubular body is shaped as a torus and configured for disposal around a patient's tracheostomy tube and has a latitudinal curvature configured to match a patient's neck proximate to the tracheostomy tube, such that the aspiration openings are disposed proximate to the tracheostomy tube;
a first airway tube and a second airway tube, both connected endwise to opposite ends of the tubular body; and
a wye conduit having a conduit inlet and first and second conduit branches, wherein the first conduit branch is connected to the first airway tube and the second conduit branch is connected to the second airway tube, and the conduit inlet is configured for connection to a vacuum source.
16 . The wearable suction catheter of claim 15 , further comprising a cleaning port in the wye conduit disposed between the conduit inlet and the conduit branches.
17 . The wearable suction catheter of claim 16 , further comprising a cap on the cleaning port configured for selectively opening the cleaning port.
