An embodiment of a flange member includes a base portion adapted to receive a proximal end of a cannula, a first flange disposed on a first side of the base portion, and a second flange member disposed on a second side of the base portion opposite the first side. The first flange and the second flange are adapted to rest against a patient's neck to maintain the flange member outside of a patient's airway. The flange member also includes a biocompatible pad reversibly integrated with at least one of the base portion, the first flange, and the second flange. ## Claims ### Claim 1 A tracheostomy tube assembly, comprising: a cannula comprising a distal end and a proximal end, the distal end being configured to be inserted into a patient's trachea; a flange member disposed about the proximal end of the cannula and configured to support the tracheostomy tube assembly via engagement with a patient's neck to maintain the flange member outside of the patient's trachea, wherein the flange member comprises a recess formed as a continuous annular ring; and a pad formed as an annular ring, wherein at least a portion of the pad is configured to be received in the continuous annular recess of the flange member to couple the pad to the flange member such that a ring-shaped surface of the pad abuts the patient's neck when the flange member supports the tracheostomy tube assembly via engagement with the patient's neck. ### Claim 2 (depends on 1) The tracheostomy tube assembly of claim 1, comprising a conduit disposed on the proximal end of the cannula and being configured to operatively connect to a medical device. ### Claim 3 (depends on 2) The tracheostomy tube assembly of claim 2, wherein the medical device comprises an airway accessory, a ventilator, a humidifier, or a combination thereof. ### Claim 4 (depends on 1) The tracheostomy tube assembly of claim 1, wherein the pad comprises an antimicrobial compound, a biocompatible polymer, a gelatinous material, an adhesive material, or a combination thereof. ### Claim 5 (depends on 1) The tracheostomy tube assembly of claim 1, wherein the flange member comprises at least one aperture proximal to the continuous annular recess and configured to enable airflow to a stoma site of the patient. ### Claim 6 (depends on 1) The tracheostomy tube assembly of claim 1, wherein the flange member comprises a central portion configured to receive the proximal end of the cannula and a first flange and a second flange disposed on opposite sides of the central portion, and wherein a first stepped portion and a second stepped portion couple the first flange and the second flange, respectively, to the central portion, and wherein the pad is configured to extend outward from the central portion to engage with the patient's neck. ### Claim 7 (depends on 1) The tracheostomy tube assembly of claim 1, wherein the flange member comprises a base portion configured to receive the proximal end of the cannula and a first flange and a second flange disposed on opposite sides of the base portion, and wherein the pad and the base portion are configured to rest against the patient's neck. ### Claim 8 (depends on 1) The tracheostomy tube assembly of claim 1, comprising a cuff disposed about the distal end of the cannula and configured to be inflated to seal against walls of the patient's trachea. ### Claim 9 (depends on 1) The tracheostomy tube assembly of claim 1, wherein the flange member comprises a pair of apertures configured to receive securement straps adapted to secure the tracheostomy tube assembly to the patient's neck. ### Claim 10 A flange member for an airway device, the flange member comprising: a base portion comprising a central aperture configured to receive a proximal end of a cannula and a continuous annular recess disposed about the central aperture; a first flange disposed on a first side of the base portion; a second flange disposed on a second side of the base portion opposite the first side, wherein the first flange and the second flange are configured to rest against a patient's neck to maintain the flange member outside of a patient's airway; and an annular biocompatible pad, wherein the annular biocompatible pad is configured to be received in the continuous annular recess of the base portion and to abut the patient's neck when the first flange and the second flange rest against the patient's neck. ### Claim 11 (depends on 10) The flange member of claim 10, wherein the annular biocompatible pad comprises an antimicrobial compound, a biocompatible polymer, a gelatinous material, an adhesive material, or a combination thereof. ### Claim 12 (depends on 10) The flange member of claim 10, wherein the annular biocompatible pad is configured to extend outward from the base portion to engage with the patient's neck. ### Claim 13 (depends on 10) The flange member of claim 10, wherein the annular biocompatible pad comprises a slit configured to facilitate removal of the annular biocompatible pad from at least one of the base portion, the first flange, and the second flange. ### Claim 14 (depends on 10) The flange member of claim 10, comprising one or more apertures disposed in at least one of the base portion, the first flange, and the second flange in a position proximate to the annular biocompatible pad and configured to facilitate airflow to a stoma site of a patient. ### Claim 15 (depends on 10) The flange member of claim 10, wherein the first flange and the second flange each comprises an aperture configured to receive securement straps adapted to secure the flange member to the patient's neck. ### Claim 16 A flange member for an airway device, the flange member comprising: a base portion comprising a central aperture configured to receive a proximal end of a cannula and a continuous annular recess disposed about the central aperture and configured to receive a biocompatible pad formed as an annular ring; a first flange disposed on a first side of the base portion; a second flange disposed on a second side of the base portion opposite the first side, wherein the first flange and the second flange are configured to rest against a patient's neck to maintain the flange member outside of a patient's airway; and one or more apertures disposed in at least one of the base portion, the first flange, and the second flange, and being configured to enable airflow to a stoma site of a patient. ### Claim 17 (depends on 16) The flange member of claim 16, wherein a first stepped portion and a second stepped portion couple the first flange and the second flange, respectively, to the base portion. ### Claim 18 (depends on 17) The flange member of claim 17, wherein the biocompatible pad is configured to extend outward from the base portion to engage with the patient's neck when the first flange and the second flange rest against the patient's neck. ### Claim 19 (depends on 16) The flange member of claim 16, wherein the one or more apertures comprises two apertures disposed in the base portion about the continuous annular recess. ### Claim 20 (depends on 19) The flange member of claim 19, wherein the two apertures are semicircular apertures disposed about the circumference of the continuous annular recess.
