Airway management device
The invention provides a device for inserting an infraglottic airway or an imaging device into a patient, the device comprising an open channel which is curved along its length, a first end of the device comprising a handle portion and a second end of the device being configured, in use, to extend to the opening of the patient's trachea. The invention also provides an infraglottic airway device comprising an endotracheal tube and two annular inflatable cuffs, wherein each cuff is provided with an inflation line through which the cuffs can be inflated or deflated.
1 . A device for inserting an infraglottic airway or an imaging device into a patient, the device comprising:
(a) a base portion of the device, the base portion having a length and being curved along the length and having integrally formed upstanding walls at either side of base to form an open channel, wherein the open channel comprises an upper hump and a lower hump at positions along the length of the base, wherein the lower and upper humps direct a medical device or tube along the open channel, thereby preventing the medical device or tube from becoming lodged within a curved region of the open channel;
(b) a first end of the device comprising a handle portion; and
(c) a second end of the device being configured, in use, to extend to the opening of the patient's trachea.
2 . A device according to claim 1 , wherein the second end of the device is also configured to occlude the esophagus of the patient.
3 . A device according to claim 1 , wherein the channel is curved along its length through an angle of from 70° to 120°.
4 . A device according to claim 1 , wherein the channel is curved along its length through an angle of from 80° to 100°.
5 . A device according to claim 1 , wherein the length of the channel is from 150 mm to 250 mm.
6 . A device according to claim 1 , wherein the depth of the channel is from 15 mm to 30 mm.
7 . A device according to claim 1 , formed from a material having a Shore 00 Hardness of from 40 to 80.
8 . A device according to claim 1 , formed from a silicone thermoplastic elastomer.
9 . A device according to claim 1 , wherein the device is provided with cushioning at one or more regions of the device.
10 . A device according to claim 9 , wherein the cushioning is in the form of a soft tongue at the second end of the device.
11 . A device according to claim 9 , wherein the cushioning is provided at the second end of the device in the form of a hollowed out opening.
12 . A device according to claim 9 , wherein the cushioning has a Shore 00 hardness in the range of from 20 to 40.
13 . A device according to claim 1 , wherein the handle portion comprises a tab extending from the device, wherein the tab comprises a stopper which prevents the user's thumb from sliding back off the end of the tab when the device is pulled by the user.
14 . A method of intubating a patient, the method comprising:
i) inserting a device according to claim 1 into a patient's throat;
ii) inserting an airway device into the patient by passing the airway device along the open channel of the device;
iii) securing the airway device within the patient; and
iv) removing the device from the patient.
15 . A method according to claim 14 wherein the second end of the device is also configured to occlude the esophagus of the patient.
16 . A method according to claim 14 wherein the depth of the channel is from 15 mm to 30 mm.
17 . A method according to claim 14 wherein the device is provided with cushioning at one or more regions of the device.
18 . A method according to claim 17 wherein the cushioning is in a form of a soft tongue at the second end of the device.
19 . A method according to claim 17 wherein the cushioning is provided at the second end of the device in a form of a hollowed out opening.
