Abstract

An oropharyngeal airway device and related methods. The device comprises: a conduit having a proximal end and a distal end, wherein on insertion into the mouth of a patient the proximal end locates in the mouth, with a front wall of the conduit facing the tongue to forwardly press against the tongue, and a rear wall of the conduit facing the palate. The conduit is convertible between a closed configuration and an open configuration. In use, conversion from the closed configuration to the open configuration opens the rear wall of the conduit, with the front wall of the conduit maintained in position against the tongue.

Claims (15)

Claims
1. An oropharyngeal airway device comprising: a conduit having a proximal end and a distal end, wherein on insertion into the mouth of a patient the proximal end locates in the mouth, with a front wall of the conduit facing the tongue to forwardly press against the tongue, and a rear wall of the conduit facing the palate; wherein the conduit is convertible between a closed configuration and an open configuration, characterised in that in use, conversion from the closed configuration to the open configuration opens the rear wall of the conduit, with the front wall of the conduit maintained in position against the tongue.
2. The oropharyngeal airway device of claim 1 , wherein the front wall of the conduit is generally concave.
3. The oropharyngeal airway device of claim 1 or 2, wherein the conduit is curved.
4. The oropharyngeal airway device of any preceding claim, wherein the conduit has uniform cross-section along its length.
5. The oropharyngeal airway device of any preceding claim, wherein with the conduit in the closed configuration the distal end of the front wall and the distal end of the rear wall are aligned, and/or the proximal end of the front wall and the proximal end of the rear wall are aligned.
6. The oropharyngeal airway device of any preceding claim, wherein with the conduit in the open configuration the distal end of the front wall and the distal end of the rear wall are aligned, and/or the proximal end of the front wall and the proximal end of the rear wall are aligned.
7. The oropharyngeal airway device of any preceding claim further comprising a flange at the proximal end of the conduit, the flange being convertible between a closed configuration and an open configuration on conversion of the conduit between the closed configuration and the open configuration thereof.
8. The oropharyngeal airway device of claim 7, wherein the flange is separable into two parts (front part and rear part) on conversion of the flange between the closed configuration and the open configuration.
9. The oropharyngeal airway device of claim 8, wherein the flange comprises interlocking mechanical features to hold the parts thereof together in the closed configuration.
10. The oropharyngeal airway device of any preceding claim, wherein the conduit is separable into two parts, by removal of a removable panel on the rear wall, on conversion of the conduit between the closed configuration and the open configuration.
11. The oropharyngeal airway device of claim 10 as dependent on claim 8 or 9, wherein the removable panel is connected to a rear part of the flange.
12. The oropharyngeal airway device of claim 10 or 11 , wherein the conduit comprises interlocking mechanical features on the rear wall and the panel to hold the conduit in the closed configuration.
13. The oropharyngeal airway device of any preceding claim, wherein the conduit comprises a separation line on the rear wall thereof, and wherein converting the conduit between the closed configuration and the open configuration comprises splitting the conduit along the separation line.
14. The oropharyngeal airway device of any preceding claim, wherein the separation line comprises a tear line formed in the rear wall of the conduit, and wherein converting the conduit between the closed configuration and the open configuration comprises tearing the conduit along the tear line.
15. A tracheal intubation method performed using the oropharyngeal airway device of any preceding claim, the method comprising: inserting the oropharyngeal airway device into the mouth of a patient a patient such that the proximal end locates in the mouth with a front wall of the conduit facing the tongue to forwardly press against the tongue, and the rear wall of the conduit facing the palate, the oropharyngeal airway device being in the closed configuration; guiding a flexible intubation scope through the conduit of the oropharyngeal airway device to the trachea of the patient; converting the oropharyngeal airway device to the open configuration while maintaining the front wall of the conduit in position against the tongue of the patient; and with the flexible intubation scope maintained in the trachea of the patient, removing the oropharyngeal airway device from the flexible intubation scope via the open rear wall of the conduit.
