Yankauer suction device with auxiliary access port
Aspects are directed to an improved suction catheter that increases the effectiveness of clearing the airway, reducing the need for separate suctioning and foreign body grasping instruments. The embodiments described herein provide medical personnel the ability to use one hand and catheter to selectively grasp an anatomically lodged foreign body while reducing the likelihood of lumen blockage and interruption of suction. The embodiments described herein further provide an auxiliary access port that allows insertion of a bougie instrument into a suction catheter. The suction catheter may be a Yankauer device or improved suction catheter with grasping housing. The bougie instrument may extend through the access port and a lumen of the catheter while still providing suction via the lumen. Due to the small size of the suction catheter, the bougie instrument may extend from the catheter's distal end when placed in close proximity to a patient's vocal cords.
1 . A method, comprising:
inserting a bougie instrument into an auxiliary access port of an oropharyngeal suction catheter while a distal end of the oropharyngeal suction catheter is placed near a vocal cord of a patient,
wherein the auxiliary access port is located on the oropharyngeal suction catheter and comprises an opening and a hollow bore in fluid communication between the opening and a lumen of the oropharyngeal suction catheter, and wherein the bougie instrument comprises an elongate shaft and an angled distal end configured to provide tactile feedback that aids advancement as the bougie instrument moves through a trachea of the patient;
pushing the bougie instrument through the hollow bore of the auxiliary access port and into the lumen of the oropharyngeal suction catheter; and
extending the bougie instrument through the hollow bore and the lumen until the angled distal end of the bougie instrument exceeds the distal end of the oropharyngeal suction catheter and the vocal cord to facilitate guidance of an endotracheal tube past the vocal cord of the patient.
2 . The method of claim 1 , wherein the pushing and the extending are done while maintaining suction to the distal end of the oropharyngeal suction catheter.
3 . The method of claim 1 , wherein the auxiliary access port further comprises a sealing membrane within the hollow bore that seals the lumen from the opening, the method further comprising:
piercing the sealing membrane to allow the bougie instrument to extend through the hollow bore and into the lumen.
4 . The method of claim 1 , further comprising:
providing at least one of oxygen or medication via the auxiliary access port.
5 . The method of claim 1 , wherein the oropharyngeal suction catheter further comprises a plurality of auxiliary suction channels fluidly connected to the lumen extending from the distal end of the oropharyngeal suction catheter to a proximal end of the oropharyngeal suction catheter.
6 . The method of claim 1 , further comprising:
moving a grasping housing distally along the oropharyngeal suction catheter until a grasping tip of the grasping housing extends from a first, closed configuration to a second, open configuration distally beyond the distal end of the oropharyngeal suction catheter, and wherein the grasping housing is slidably disposed around at least a portion of the oropharyngeal suction catheter; and
moving the grasping housing distally along the oropharyngeal suction catheter until the grasping tip extends from the second, open configuration to a third, closed configuration distally beyond the second, open configuration relative to the distal end of the oropharyngeal suction catheter.
7 . The method of claim 1 , wherein the oropharyngeal suction catheter comprises a diameter of between one and ten millimeters.
8 . A method, comprising:
positioning a distal end of an oropharyngeal suction catheter near a vocal cord of a patient, wherein the oropharyngeal suction catheter comprises a lumen extending from a proximal end to the distal end and an auxiliary access port located closer to the proximal end than the distal end, the auxiliary access port comprising an opening and a hollow bore in fluid communication with the lumen;
inserting a bougie instrument through the auxiliary access port and into the lumen of the oropharyngeal suction catheter, the bougie instrument comprising an angled distal end;
advancing the bougie instrument through the lumen until a distal end of the bougie instrument extends beyond the distal end of the oropharyngeal suction catheter, using the angled distal end to provide tactile feedback while the bougie instrument moves through a trachea of the patient; and
advancing an endotracheal tube over the bougie instrument past the vocal cord of the patient.
9 . The method of claim 8 , further comprising:
maintaining suction through the lumen of the oropharyngeal suction catheter during insertion and advancement of the bougie instrument.
10 . The method of claim 8 , wherein the auxiliary access port comprises a sealing membrane, and wherein inserting the bougie instrument comprises piercing the sealing membrane.
11 . The method of claim 8 , further comprising:
delivering at least one of oxygen or medication through the auxiliary access port prior to advancing the endotracheal tube.
12 . The method of claim 8 , wherein the oropharyngeal suction catheter comprises a plurality of auxiliary suction channels fluidly connected to the lumen.
13 . The method of claim 8 , wherein the oropharyngeal suction catheter comprises a curved configuration with a radius of curvature adapted to navigate an oropharyngeal cavity of the patient.
14 . The method of claim 8 , wherein the oropharyngeal suction catheter comprises a disposable single-use device.
15 . A method, comprising:
inserting a suction catheter into an oropharyngeal cavity of a patient until a distal end of the suction catheter is positioned near to a vocal cord of the patient, wherein the suction catheter comprises a lumen extending from a proximal end to the distal end and an auxiliary access port in fluid communication with the lumen;
applying suction through the lumen to remove matter from the oropharyngeal cavity;
inserting a bougie instrument into the auxiliary access port of the suction catheter, the bougie comprising an angled distal end;
advancing the bougie instrument through the lumen until the angled distal end of the bougie instrument extends beyond the distal end of the suction catheter, using the angled distal end to provide tactile feedback while the bougie instrument moves across rings of a trachea of the patient; and
guiding an endotracheal tube over the bougie instrument into the trachea of the patient.
16 . The method of claim 15 , wherein the suction is maintained during insertion and advancement of the bougie instrument.
17 . The method of claim 15 , wherein the auxiliary access port comprises a sealing membrane, and the inserting the bougie instrument further comprises:
piercing the sealing membrane by the bougie instrument.
18 . The method of claim 15 , further comprising:
delivering oxygen through the auxiliary access port during at least a portion of the inserting the suction catheter, inserting the bougie instrument, advancing the bougie instrument, or guiding the endotracheal tube.
19 . The method of claim 15 , wherein the suction catheter comprises auxiliary suction channels extending along a length of the lumen.
20 . The method of claim 15 , further comprising:
grasping and removing a foreign body from the oral cavity using a grasping housing slidably disposed on the suction catheter prior to inserting the bougie instrument.
21 . The method of claim 15 , wherein the suction catheter has a diameter of between one and ten millimeters.
