[0047] Reference is made to FIGS. 1-2, which show an endotracheal safety device 100. The endotracheal safety device 100 may include an endotracheal tube 114, an adapter 120, and an endotracheal sleeve assembly 102. The endotracheal sleeve assembly 102 may include a clamp 104, a tightening device 106, a flange 110, and a strap 124. The endotracheal tube 114 may have a proximal end 126 and a distal end 118. The endotracheal tube 114 may have at least one marking 112 on the outer surface of the endotracheal tube 114. The endotracheal tube 114 may have a cuff inflation port 112 for inflating the cuff 116 and at least one marking 122.
[0048] With continued reference to FIGS. 1-2 and further reference to FIGS. 3-4, endotracheal sleeve assembly 102 may have a proximal end and a distal end. The proximal end may define at least one stop. The endotracheal sleeve assembly 102 may define a lumen between the proximal end and a distal end such that the lumen of the endotracheal sleeve assembly 102 may fit over the endotracheal tube 114. The endotracheal sleeve assembly 102 is configured such that the endotracheal sleeve assembly 102 is slidably movable over the endotracheal tube 114. The endotracheal sleeve assembly 102 may include a clamp 104 for securing the endotracheal sleeve assembly 102 onto the endotracheal tube 114 such that the endotracheal sleeve assembly 102 is not slidably movable. The clamp 104 may be tightened via a tightening device 106, such as a thumbscrew. The endotracheal sleeve assembly 102 may be tightened and secured to the endotracheal tube 114 via other conventional means. The endotracheal sleeve assembly 102 may be made of any suitable material. For example, the endotracheal sleeve assembly 102 may be made of rigid, clear plastic. The clear plastic allows the markings 122 to be visible when the endotracheal sleeve assembly 102 is placed over the endotracheal tube 114. The endotracheal sleeve assembly 102 may vary in length. For example, the sleeve may be 1-5 inches long, 1-2.5 inches long, 1-2 inches long, or any suitable length.
[0049] With continued reference to FIGS. 1-2 and further reference to FIG. 3-4, the endotracheal sleeve assembly 102 may include a flange 110. The flange 110 may be integral with the endotracheal sleeve assembly 102 or removably attached to the endotracheal sleeve assembly 102. The flange 110 may have a concave shape so as to ergonomically fit over a patient's mouth. The endotracheal sleeve assembly 102 may include a strap 124. The strap may be attached to the flange 110 or the endotracheal sleeve assembly 102. The strap may 124 may be secured around a patient's head to hold the endotracheal safety device 100 in place once the endotracheal tube 114 is inserted into the patient. The strap 124 may be made of any suitable material, such as Velcro. Use of the strap 124 eliminates the need to use tapes to secure the endotracheal safety device 100 to a patient.
[0050] Now with reference to FIG. 5, the endotracheal safety device 100 may be assembled by combining the endotracheal tube 114, the endotracheal sleeve assembly 102, and the adapter 120. The lumen of the endotracheal sleeve assembly 102 goes over the outer surface of the endotracheal tube 114. The adapter 120 may have a distal end having a circumference smaller than that of the proximal end of the endotracheal tube 114 such that the adapter 120 may be received by the endotracheal tube 114. Alternatively, the adapter 120 may have a distal end having a circumference bigger than that of the proximal end of the endotracheal tube 114 such that the endotracheal tube 114 is received by the adapter 120. The adapter 120 and the endotracheal tube 114 may be secured together by friction fit, for example, the endotracheal tube 114 and the adapter 120 may have threads to allow a screw fit. Alternatively, the adapter120 and the endotracheal tube 114 may be held in place by any other traditional means. Furthermore, the adapter 120 and the endotracheal tube 114 may be integrally connected to each other. The adapter 120 with an integral connection prevents the endotracheal tube 114 from being easily disconnected from the breathing circuit, thereby preventing loss of oxygenation and ventilation.
[0051] With continued reference to FIG. 5, the endotracheal tube 114 may have a proximal end 126 and a distal end 118. The proximal end 126 may be configured to receive the adapter 120. The inner surface of the lumen of the endotracheal tube 114 at its proximal end may comprise threads that can provide a screw friction fit with the adapter 120. The distal end 118 of the endotracheal tube 114 may be tapered, such that the circumference at the distal end 118 is smaller than the rest of the endotracheal tube. 114. For example, the distal end 118 may be less than 75%, less than 50%, less than 25%, one half centimeter smaller, or any other suitable size smaller than the size of the rest of the endotracheal tube 114. The distal end 118 may be beveled. The distal end 118 may also be bent. For example, the distal end 118 may be bent at an angle between 0-50 degrees, 20-40 degrees, and 25-35 degrees. Furthermore, the distal side of the endotracheal tube 114 may be bent at a substantially 90 degree angle. For example, the distal side of the endotracheal tube 114 may be bent at an angle between 60 degrees and 90 degrees, 65 degrees and 85 degrees, and 70 degrees and 80 degrees. Such bend in the endotracheal tube 114 allows for easier placement of the endotracheal tube 114 into the trachea of a patient without the use of an intubating stylet. The endotracheal tube 114 may straighten itself out once the endotracheal tube 114 is inserted into a patient and warms up to the patient's body temperature. The endotracheal tube 114 may include a cuff 116. The cuff 116 may be in fluid communication with the cuff inflation port 112 such that air introduced into the cuff inflation port 112 may in turn inflate the cuff 116. For example, the cuff 116 may be inflated once the cuff 116 is introduced into a patient beyond the vocal cords. The endotracheal tube 114 may have one or more markings 122. The markings 122 may indicate how far the endotracheal tube 114 has been inserted into a patient, as well as mark where on the endotracheal tube 114 the endotracheal sleeve assembly 102 is secured. For example, the markings 112 may be any units of measurement, such as centimeters or units, or any indication of desired length of insertion.
[0052] With reference to FIGS. 6 and 7, an end user may prepare the endotracheal safety device 100. For example, the end user may place the endotracheal sleeve assembly 102 over the endotracheal tube 114 such that the endotracheal sleeve assembly 102 is easily movable over the endotracheal tube 114. The end user may connect the adapter 120 to the endotracheal tube 114. The end user may slide the distal end 118 of the endotracheal tube 114, with the cuff 116 deflates, through the vocal cords. After putting together the endotracheal safety device 100, the end use may slide the cuff 116 from the distal end 118 to where the bend begins at the distal side of the endotracheal tube 114. The end user may insert the endotracheal safety device 100 into the trachea 302 of a patient 300 by inserting the distal end 118 of the endotracheal tube 114. For example, the endotracheal safety device 100 may be inserted at 21 cm, or any suitable distance, from the patient's lip. The end user may determine the how much of the endotracheal tube 114 has been inserted by examining the one or more markings 122, as well as auscultating the lungs and checking for positive ETCO2. Once a desired length of the endotracheal tube 114 is inserted, which the end user can determine by looking at the markings 122, the end user may slidably move the endotracheal sleeve assembly 102 towards the mouth of the patient 300 to such that the flange 110 of the endotracheal sleeve assembly 102 is in contact with the mouth of the patient 300. Once the endotracheal sleeve assembly 102 is in its desired position, the end user may secure the endotracheal sleeve assembly 102 in place with respect to the endotracheal tube 114 by tightening the clamp 104 via the tightening device 106. The end user then may inflate the cuff 116 by introducing air into the cuff inflation port 112. The end user may secure the endotracheal safety device 100 on the patient 300 by placing the strap 124 around the patient's head and securing both ends of the strap 124 be on the flange 106.
[0053] With reference to FIG. 8, the endotracheal safety device 100 may be placed in sterile packaging 128 before use for storage purposes. The endotracheal safety device 100 may be packaged such that the endotracheal sleeve assembly 102, the endotracheal tube 114, and the adapter 120 are contained in one packaging 128, as shown on the left. Alternatively, separate components of the endotracheal safety device 100 may be packaged. For example, only the endotracheal sleeve assembly 102 and its related components may be present in one packaging 128, as shown on the right.
[0054] Reference is made to FIG. 9, which shows the endotracheal safety device 200 according to a non-limiting embodiment or aspects. The disclosures of the endotracheal safety device 100 and the disclosures of the endotracheal safety device may be used interchangeably as appropriate. The endotracheal safety device 200 may include an endotracheal sleeve assembly 202, an endotracheal tube 212, and an adapter 224. The endotracheal sleeve assembly 202 may include a flange 206 and a strap 222. The flange 206 may define one or more holes 210. The endotracheal sleeve assembly 202 may include a clamping assembly having a coupler 204 and one or more slits 208. The endotracheal tube 212 may define a proximal end 220 and a distal end 218. The endotracheal tube 212 may include a cuff 216 and a cuff inflation port 226.
[0055] With reference to FIG. 10, the endotracheal tube 212 may have a proximal end 220 that is configured to receive a distal end of the adapter 224. Alternatively, the distal end of the adapter 224 may be configured to receive the proximal end 220 of the endotracheal tube 212. The distal end of the adapter 224 and the proximal end 220 of the endotracheal tube 212 may have corresponding structure that will fasten the adapter 224 and the endotracheal tube 212 in place. For example, the proximal end 220 of the endotracheal tube 212 and the distal end of the adapter 224 may have threads, as to provide a screw fit. The endotracheal tube 212 may further include markings 214 that may indicate how far the endotracheal tube 212 has been inserted into a patient. Additionally, the markings 214 may indicate where the endotracheal sleeve assembly 202 is placed with respect to the endotracheal tube 212. The endotracheal tube 212 may include a cuff 216 and a cuff inflation port 226. The cuff inflation port 226 and the cuff 216 may be in fluid communication such that air introduced to the cuff inflation port 226 may inflate the cuff 216. The distal side of the endotracheal tube 212 may be bent at a substantially 90 degree angle, as shown on the right compared to the non-bent endotracheal tube on the left. For example, the distal side of the endotracheal tube 212 may be bent at an angle between 60 degrees and 90 degrees, 65 degrees and 85 degrees, and 70 degrees and 80 degrees. Such bend in the endotracheal tube 212 allows for easier placement of the endotracheal tube 212 into the trachea of a patient without using an intubating stylet. The bent endotracheal tube 212 may be straightened out once the endotracheal tube 212 is inserted, with the cuff 216 inflates, and the endotracheal tube 212 warms up to the patient's body temperature. The endotracheal tube 212 may define a distal end 218 that is beveled, as shown on the right. The distal end 218 may define an opening, as shown on the left. The opening may coincide with the distal end 218, or may be defined on the tracheal tube 212 a predetermined distance away from the distal end 218, for example, between 0.0 to 1.5 inch, 0.0 to 1.0 inch, and 0.0 to 0.5 inch away from the distal end 218 of the endotracheal tube 212. The opening may be of any suitable shape, such as an oval. The opening may be of any suitable size, for example, between 0.0 inch to 1 inch and 0.25 to 0.75 inch in width and length.
[0056] With reference to FIGS. 11-12, the endotracheal sleeve assembly 202 may include a flange 206 defining at least one hole 210, a strap 222, a coupler 204, one or more slits 208, and at least one stop 203 at the proximal end of the endotracheal sleeve assembly 202. FIG. 11 shows the endotracheal sleeve assembly 202 with the coupler 204 separate from the endotracheal sleeve assembly 202. The flange 206 may have a may have a concave shape so as to ergonomically fit over a patient's mouth. FIG. 11 shows the coupler 204 in its first position where the coupler 204 is mounted on the endotracheal sleeve assembly 202 such that the coupler 204 is not exerting any compressive forces on one or more slits 208. The one or more stops 203 prevents the coupler 204 from being disconnected from the endotracheal sleeve assembly 202. The one or more stops 203 may be a flange, an obstruction, or any other suitable structure that prevents the coupler 203 from being removed from the endotracheal sleeve assembly 202. FIG. 12 shows the coupler 204 in its second position where the coupler 204 is mounted on the endotracheal sleeve assembly 204 such that the coupler 204 is placed over one or more slits 208. Then one or more slits 208 may be pressed against the endotracheal tube 212 when the coupler 204 is in its second position. The coupler 204 may be made of any suitable rigid material such that the coupler 204 is configured to apply compressive forces on the one or more slits 208. Such compressive force applied on the one or more slits 208 in turn applies a compressive force onto the endotracheal tube 212. This allows the endotracheal sleeve assembly 202 to be fixed in position in relation to the endotracheal tube 212. The strap 222 may be attached to the flange 206 and/or the at least one hole 210 of the flange. The strap 222 may be used to further secure the endotracheal safety device 200 in place after the endotracheal tube 212 has been inserted into a patient.
[0057] While this disclosure has been described as having exemplary designs, the present disclosure can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the disclosure using its general principles. Further, this application is intended to cover such departures from the present disclosure that are known or customarily practiced in the art to which this disclosure pertains and which fall within the limits of the appended claims.
