Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an integrated device for endotracheal tube fixation and oral suction. Background Technology

[0002] Endotracheal intubation is a method of inserting a specially designed endotracheal tube through the mouth or nose and through the glottis into the trachea or bronchus. It provides optimal conditions for airway patency, ventilation and oxygen supply, and airway suction, and is an important measure for rescuing patients with respiratory dysfunction.

[0003] Currently, the endotracheal tube fixation devices used in clinical practice to fix the endotracheal tube to the patient's lips are usually just a conventional cylindrical device that is fitted over the endotracheal tube. However, in clinical use, this often causes mechanical pressure damage to the patient's lips and oral cavity during the endotracheal tube insertion process. This is not conducive to the patient's continuous use for a long time, causing discomfort to the patient and further affecting other treatment processes of medical staff.

[0004] Therefore, how to provide a novel integrated device for endotracheal intubation fixation and oral suction to expand the contact area of ​​the lips and mouth, improve patient comfort, and reduce pressure-related damage to the patient's lips and tongue during endotracheal intubation is a technical problem that urgently needs to be solved by those skilled in the art.

[0016] Beneficial effects:

[0017] This utility model provides an integrated device for endotracheal tube fixation and oral suction, including an annular cuff, a fixing tube, and an inflation tube. The fixing tube has a C-shaped structure with an opening on its side wall, forming a non-closed clamp structure. Since some patients have already had an endotracheal tube inserted, by making the fixing tube a C-shaped clamp structure, it is convenient to fit and fix the integrated device onto the endotracheal tube fixation and oral suction when the endotracheal tube has already been inserted, avoiding the need to remove the endotracheal tube for re-fitting, thus improving patient comfort and ease of operation for medical staff. The fixing tube includes an integrally formed cuff fixing part and an occlusal part. The cuff fixing part is arranged adjacent to and above the occlusal part. The cuff fixing part is used to fix the annular cuff, and the inner size of the annular cuff is adapted to the outer size of the cuff fixing part, so that... The inner ring of the annular cuff is fixed to the outer wall of the cuff fixation part. The shape of the annular cuff is adapted to the internal structure of the patient's oral cavity, expanding the contact surface of the lips and oral cavity. The annular cuff is made of soft material, reducing the instrument-induced pressure injury caused by the endotracheal intubation fixation device currently used in clinical practice. One end of the air inlet tube is connected to the annular cuff to supply air into the annular cuff. A first channel is opened through the occlusal part, and the other end of the air inlet tube passes through the first channel and is connected to a one-way valve.

[0041] Please see Figure 1-3 This embodiment provides an integrated device for endotracheal tube fixation and oral suction. The integrated device includes an annular airbag 1, a fixing tube 2, and an injection tube 3. The fixing tube 2 has a C-shaped structure with an opening on its side wall, so that the fixing tube 2 forms a non-closed tube clamp structure. The endotracheal tube is placed inside the fixing tube 2 through the opening. The fixing tube 2 includes an integrally formed airbag fixing part 21 and an occlusal part 22. The airbag fixing part 21 is arranged adjacent to the upper part of the occlusal part 22. The annular airbag 1 has an annular structure adapted to the C-shaped structure. The annular airbag 1 is wrapped around the periphery of the airbag fixing part 21 and is fixedly connected to the outer wall of the airbag fixing part 21. One end of the injection tube 3 is connected to the annular airbag 1. The occlusal part 22 has a first channel 221 through it. The other end of the injection tube 3 passes through the first channel 221 and is connected to a one-way valve.

[0042] Specifically, this utility model provides an integrated device for endotracheal tube fixation and oral suction, comprising an annular cuff 1, a fixing tube 2, and an inflation tube 3. The fixing tube 2 has a C-shaped structure with openings on its side walls, forming a non-closed clamp structure. Since some patients have endotracheal tubes pre-inserted, by making the fixing tube 2 a C-shaped clamp structure, it is convenient to fit and fix the integrated device for endotracheal tube fixation and oral suction onto the pre-inserted endotracheal tube, avoiding the need to remove the endotracheal tube for re-insertion, thus improving patient comfort and ease of operation for medical staff. The fixing tube 2 includes an integrally formed cuff fixing part 21 and an occlusal part 22. The cuff fixing part 21 is arranged adjacent to and above the occlusal part 22, and the cuff fixing part 21 is used to fix the annular cuff. The inner ring of the annular airbag 1 is adapted to the outer ring of the airbag fixing part 21, so that the inner ring of the annular airbag 1 is fixed to the outer wall of the airbag fixing part 21. As an example, the outer ring of the annular airbag 1 is arc-shaped, so that after inflation, the outer periphery of the annular airbag 1 forms a horizontal egg-shaped structure, which adapts to the internal structure of the patient's oral cavity, expands the contact surface of the lips and oral cavity, and the annular airbag 1 is made of soft material, reducing the instrument-induced pressure injury caused by the endotracheal intubation fixation device currently used in clinical practice. As another example, the inflation volume of the annular airbag 1 can be controlled according to the size of the patient's oral cavity, allowing for subsequent pressure monitoring through the air injection tube 3, so as to achieve the purpose of fixation and decompression more scientifically. One end of the air injection tube 3 is connected to the annular airbag 1 to supply air into the annular airbag 1 through the air injection tube 3. Figure 4 As shown, the occlusal portion 22 has a first channel 221 through which the other end of the air inlet tube 3 passes through the first channel 221 and is connected to a one-way valve. With the setting of the first channel 221, the occlusal portion 22 is not only located in the patient's lips and teeth during use, but the air inlet tube 3 can also be hidden in the occlusal portion 22 and pass through it. In this way, a new type of integrated device for endotracheal tube fixation and oral suction is constructed, which expands the contact surface of the lips and oral cavity, improves the patient's comfort, and reduces pressure-related damage to the patient's lips and tongue during endotracheal intubation.

[0043] In some possible embodiments, the integrated endotracheal tube fixation and oral suction device also includes an outer membrane 4, which is a hemispherical structure with an opening on the side. The outer membrane 4 surrounds the periphery of the annular air bladder 1, and the lower part of the outer membrane 4 is fixedly connected to the top of the occlusal part 22. The outer membrane 4, the outer surface of the annular air bladder 1, and the top surface of the occlusal part 22 together form a suction cavity. The occlusal part 22 has a second channel 222 through it. One end of the second channel 222 is connected to the suction cavity, and the other end of the second channel 222 is connected to the negative pressure suction device through a connecting tube 5.

[0044] Specifically, such as Figure 1-2 as well as Figure 3As shown, by setting the outer membrane 4, combined with the second channel 222 that runs through the occlusal part 22, the second channel 222 is connected to the negative pressure suction device through the connecting tube 5, thus constructing a suction cavity for suctioning secretions from the patient's oral cavity. Since patients use endotracheal intubation for a long time, a large amount of secretions may be generated in the oral cavity that cannot be swallowed or spat out in time. Therefore, the setting of the suction cavity makes it easier for medical staff to assist patients in draining secretions from their oral cavity during the endotracheal intubation process, thereby improving the patient's comfort.

[0045] In some possible implementations, the outer membrane 4 has a honeycomb structure, which includes a plurality of through holes 41, all of which are connected to the suction cavity.

[0046] Specifically, by setting up a honeycomb structure, on the one hand, oral secretions can be absorbed through the several holes 41 opened on the honeycomb structure, and on the other hand, the honeycomb structure can further enhance the stability of the annular airbag 1 when inflated, and play a supporting and lifting role on the outer side of the annular airbag 1, so as to maintain the shape stability of the annular airbag 1 inside the oral cavity.

[0047] In some possible implementations, the honeycomb structure is fixedly connected to the outer surface of the annular airbag 1 by a number of evenly spaced supporting soft bodies 42.

[0048] Specifically, such as Figure 5 As shown, the support soft body 42 helps to maintain a certain distance between the honeycomb structure and the outer surface of the annular airbag 1, avoiding the outer membrane 4 from sticking to the outer surface of the airbag 1 during the suction process or the patient's oral movements, thus preventing the suction of oral secretions from being obstructed.

[0049] In some possible implementations, the inner surfaces of both the airbag fixing part 21 and the biting part 22 are provided with a frosted structure.

[0050] Specifically, the frosted structure increases friction, thereby improving the stability of the airbag fixing part 21 and the biting part 22 in clamping and fixing the endotracheal tube.

[0051] In some possible implementations, the integrated endotracheal tube fixation and oral suction device further includes two fixation straps 6, one end of which is fixedly connected to opposite sides of the opening of the occlusal portion 22.

[0052] Specifically, by using two fixing straps 6, the patient can wrap the two fixing straps 6 around their head to securely fix the entire device, which integrates endotracheal tube fixation and oral suction. As one feasible method, such as... Figure 1As shown, one end of each of the two fixing straps 6 is fixedly connected to opposite sides of the opening of the occlusal portion 22, and the fixing heights of the two fixing straps 6 are staggered, so that when the patient wraps the straps, they can be adjusted according to... Figure 1 The two fixing straps 6 shown are wrapped in a cross manner. On the one hand, they can be fixed to the head, and on the other hand, the cross shape can make the openings of the fixing tube 1 be subjected to opposite forces, making the fixation between the fixing tube 1 and the endotracheal tube more secure.

[0053] In some possible implementations, the other ends of both fixing straps 6 are provided with hook and loop fasteners, and the other ends of the two fixing straps 6 are detachably glued together by the hook and loop fasteners.

[0054] Specifically, the Velcro surface allows patients or medical staff to easily and quickly fix the device by adhesive.

[0055] In some possible implementations, a soft silicone pad 223 is provided around the outer side of the biting portion 22. The size of the soft silicone pad 223 is adapted to the size of the outer side of the biting portion 22, and it has an opening adapted to the biting portion 22.

[0056] Specifically, by surrounding the outer side of the occlusal portion 22 with a soft silicone pad 223, the softness of the contact between the occlusal portion 22 and the patient's lips is improved, thereby increasing the patient's comfort. In addition, the silicone material is easy to clean and suitable for medical use.

[0057] In some possible implementations, the gas injection pipe 3 is connected to an extension pipe, which is connected to a pressure measuring device.

[0058] Specifically, the pressure in the annular airbag 1 can be measured by extending the measuring tube. The extension of the measuring tube can be set according to the commonly used clinical settings.

[0059] In some possible implementations, both the airbag fixing part 21 and the biting part 22 are made of elastic medical plastic.
