Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an intelligent fixing system for protecting a tracheal tube. Background Art

[0002] Endotracheal intubation is the most commonly used method for emergency resuscitation, surgical anesthesia, and airway opening in clinical practice. Safe fixation is the guarantee for successful intubation. In clinical practice, the fixation of the endotracheal tube of mechanically ventilated patients is particularly important, not only to avoid accidental extubation of mechanically ventilated patients, but also to prevent patients from swallowing the endotracheal tube into the airway.

[0003] A tracheal tube fixing mechanism with application number CN202222708608.2 utilizes a movable partition and a fixed bracket to isolate the tracheal tube from the outside world, thereby preventing external pollutants from entering the oral trachea and avoiding direct contact between the oral trachea and the outside world, and the movable partition does not affect the operation and fixation of the tracheal tube.

[0004] However, during the actual endotracheal intubation operation, although the oropharyngeal ventilation tube can be used to assist the installation of the endotracheal tube, after the endotracheal tube is installed, the oropharyngeal ventilation tube needs to be removed and then replaced with an anti-bite pad to fix and protect the endotracheal tube. The whole process has many steps and the operation is cumbersome. In addition, the endotracheal tube is wrapped with tape during fixation. The tape has poor fixation and is easy to shift during the use of the intubation. During use, the patient's tongue can easily flip back and forth due to swallowing movements, so the tongue will directly apply an outward thrust to the tube, which is not only not conducive to the stability of the endotracheal tube, but also when the patient uses the tongue to push outward to apply external force, it is easy to cause the tube to detach due to the poor viscosity of the tape. Therefore, the endotracheal intubations currently on the market have poor operation convenience and installation stability.

[0005] Therefore, the present invention solves the above-mentioned problem through an intelligent fixing system for protecting endotracheal tube. Summary of the invention

[0019] 2. When the present invention is actually used, the cannula body corresponds to the tongue and is above the surface of the tongue, and the patient's tongue naturally falls between the tongue depressor and the inner end of the cannula body. The patient's tongue can be effectively limited during use to prevent the patient's tongue from moving back and forth or generating an outward thrust on the cannula body due to swallowing. In this way, the tongue will naturally rest on the tongue depressor, better matching the human body structure and increasing the patient's comfort.

[0020] 3. When the patient uses his tongue to continuously squeeze the tongue depressor, the present invention can use the action of the tongue depressor to increase the pressure of the air bag on the cannula body to overcome the thrust of the patient's tongue on the cannula body outward, and can also push the first limiting plate group and the second limiting plate group to synchronously extend the fixator outward to increase the wrapping of the patient's gums, further increase the limiting property of the anti-detachment device on the patient's gums to prevent detachment. At the same time, the extension of the first limiting plate group and the second limiting plate group will increase the supporting force of the patient's gums and better fit the gums, but will cause the patient to feel uncomfortable pressure, thereby reminding the patient to avoid such dangerous actions, and can increase the safety of the cannula body during installation in a unique way.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] like Figures 1 to 9As shown, this embodiment provides an intelligent fixing system for protecting endotracheal tube, including a positioner 1, a fixer 2 is slidably mounted on the positioner 1, an anti-dropping device 3 is matched and mounted on the fixer 2, a tongue depressor 4 is hingedly mounted on the bottom rear side of the fixer 2, and a cannula body 5 is installed through the fixer 2. When medical staff use this embodiment for practical application, the cannula body 5 can be inserted into the fixer 2 to limit the position of the cannula body 5, and then the position of the fixer 2 on the positioner 1 can be manually adjusted according to actual needs, so as to facilitate the adjustment of the cannula position according to different patients, and the positioner 1 can be used to The fixator 2 is quickly aligned with the patient's oral position to achieve rapid positioning and can be firmly fixed to prevent the fixator 2 from shaking back and forth or falling off during use, causing intubation failure. The anti-slip device 3 can replace the function of the traditional tooth pad to prevent the patient from biting the intubation body 5 and causing the intubation to be closed. At the same time, the anti-slip device 3 can limit the patient's gums, so that the fixator 2 is fixed relative to the patient's gums, which can effectively prevent the fixator 2 from going too deep into the oral cavity or falling off from the oral cavity during use, greatly improve the limiting degree of the intubation body 5, and improve the safety of use.

[0034] When this embodiment is actually installed, the cannula body 5 corresponds to the tongue and is above the surface of the tongue, and the patient's tongue naturally falls between the tongue depressor 4 and the inner end of the cannula body 5, which can effectively limit the patient's tongue during use to prevent the patient's tongue from moving back and forth or generating an outward thrust on the cannula body 5 due to swallowing. In this way, the tongue will naturally rest on the tongue depressor 4 to better match the human body structure, and when the patient moves the tongue, there is only an upward push force on the cannula body 5 and no thrust is generated, but a downward thrust is generated on the tongue depressor 4, which can directly transfer the patient's tongue action object to the tongue depressor 4. With the use of the anti-detachment device 3, the fixer 2 can be prevented from detaching, and the cannula body 5 can be further prevented from falling off from the fixer 2.

[0035] See also Figure 1-Figure 3 The positioner 1 includes two groups of protective silicone sheets 101 with the same structure and symmetrical distribution. The top and bottom of the two groups of protective silicone sheets 101 are integrally formed with positioning belts 102 on the opposite sides. The two groups of protective silicone sheets 101 are fixedly connected by elastic belts 103 at the opposite ends. The gap between the two groups of positioning belts 102 can realize the installation of the fixator 2. The protective silicone sheets 101 can fit on the patient's face to improve comfort, and the elastic belt 103 can be put on the patient's head or neck, which can quickly realize the positioning and installation of the fixator 2. Then, the installation position of the fixator 2 on the positioner 1 can be changed according to actual needs, which greatly improves the installation convenience of the fixator 2 and reduces the workload of medical staff.

[0036] See also Figure 4-Figure 6 ,, the fixator 2 includes an anti-bite pad 201, which can replace the role of the tooth pad and can protect the intubation body 5. The anti-bite pad 201 is slidably assembled between the two sets of positioning belts 102. The top and bottom of the anti-bite pad 201 are integrally formed with a sliding sleeve 202 that matches the positioning belt 102, and the sliding sleeve 202 and the positioning belt 102 are self-locking through the friction between the sliding sleeve 202 and the positioning belt 102, thereby improving the safety of use. In this way, the anti-bite pad 201 can push the sliding sleeve 202 to move on the positioning belt 102 under the action of external force to change its position, and the position of the fixator 2 can be quickly adjusted.

[0037] See also Figure 4-Figure 6 A guide hole 203 is provided on the anti-bite pad 201, and the guide hole 203 facilitates the installation of the cannula body 5. A silicone pad 206 is nested on the top of the fixator 2, and the silicone pad 206 corresponds to the position of the patient's gums to protect the patient's teeth. The left and right side walls of the guide hole 203 are hinged with clamping pieces 207 through a universal ball head. A fixing sleeve 208 is fixed on the top and bottom of the guide hole 203, and an air cushion 209 is fixed on the rear side of the fixing sleeve 208. The clamping piece 207 is adapted to the cannula body 5, and the width of the guide hole 203 is greater than the distance between the two groups of clamping pieces 207. A rubber pad is provided on the surface of the fixing sleeve 208, and the fixing sleeve 208 and the air cushion 209 are fitted on the outer wall of the cannula body 5.

[0038] The clamping piece 207 can clamp the left and right side walls of the cannula body 5 to achieve the limitation of the cannula body 5. At the same time, the fixing sleeve 208 and the air cushion 209 can clamp and limit the top and bottom of the cannula body 5, which can ensure the installation limitation degree of the cannula body 5 on the fixer 2. At the same time, the friction between the cannula body 5 and the clamping piece 207, the fixing sleeve 208 and the air cushion 209 can provide the primary limitation of the cannula body 5, so that the cannula body 5 can achieve self-limitation of the installation position when it is installed on the fixer 2.

[0039] See also Figure 4-Figure 7The anti-slip device 3 includes a first limiting piece group 301 and a second limiting piece group 302 which are slidably assembled on the top and bottom of the anti-bite pad 201, and the first limiting piece group 301 and the second limiting piece group 302 are distributed on the front and back sides of the silicone pad 206. The first limiting piece group 301 and the second limiting piece group 302 have the same structural composition and are composed of a number of independent protective limiting pieces, and the protective limiting pieces are all silicone blocks. The first limiting piece group 301 and the second limiting piece group 302 are both arc-shaped, and the arcs of the first limiting piece group 301 and the second limiting piece group 302 match the gums. The first limiting piece group 301 and the second limiting piece group 302 can limit the front and back sides of the patient's gums, so that the fixator 2 is fixed relative to the patient's gums, which can effectively prevent the fixator 2 from happening during use. In the event that the cannula goes too deep into the oral cavity or comes out of the oral cavity, the limiting degree of the cannula body 5 is greatly increased, thereby improving the safety of use. The inner cavity of the anti-bite pad 201 is equipped with a supporting air bag 304, and the top of the supporting air bag 304 is connected to a buffer air bag 303 corresponding to the first limiting piece group 301 and the second limiting piece group 302. When the patient's gums generate an extrusion pressure on the first limiting piece group 301 and the second limiting piece group 302, the extrusion pressure will directly act on the buffer air bag 303 through the first limiting piece group 301 and the second limiting piece group 302, causing the buffer air bag 303 to be compressed, and then the supporting air bag 304 and the buffer air bag 303 cooperate to achieve buffering and absorption of the extrusion pressure, while providing the first limiting piece group 301 and the second limiting piece group 302 with protection for the patient's gums.

[0040] It is worth mentioning that the inner end of the silicone pad 206 is mounted against the side wall of the fixing sleeve 208. When the patient's teeth are limited between the first limiting plate group 301 and the second limiting plate group 302, the teeth will automatically fall on the silicone pad 206, and then the patient's teeth will exert pressure on the silicone pad 206 through their own bite force, which will cause the silicone pad 206 to be squeezed and deformed, and the pressure will be transmitted to the fixing sleeve 208 through the silicone pad 206, increasing the clamping force of the fixing sleeve 208 on the cannula body 5, thereby increasing the installation stability of the cannula body 5 in the fixture 2 through the patient's own bite force when the teeth are closed, thereby further preventing the cannula body 5 from detaching.

[0041] It should be noted that even if the patient bites the anti-bite pad 201 hard, the bite force will only increase the deformation of the silicone pad 206. The bite force is absorbed by the silicone pad 206, and the pressure transmitted from the silicone pad 206 to the fixing sleeve 208 increases slightly. The installation stability of the cannula body 5 can be increased without deforming the cannula body 5, thereby protecting the cannula body 5.

[0042] See also Figure 7The top and bottom of the anti-bite pad 201 are both provided with slides 204 that match the protective limiting plate, and the interior of the anti-bite pad 201 is provided with a receiving groove 205 that is connected to the slide 204. The buffer air bag 303 is accommodated in the slide 204, and the buffer air bag 303 is fixedly connected to the bottom of the protective limiting plate, and the supporting air bag 304 is accommodated in the receiving groove 205. This makes it convenient for the first limiting plate group 301 and the second limiting plate group 302 to retract into the slide when subjected to extrusion force, and can squeeze the buffer air bag 303 to achieve buffering and absorption of the extrusion force.

[0043] See also Figure 4 , Figure 6 and Figure 8 The bottom of the anti-bite pad 201 is provided with a retreat groove 210 adapted to the tongue depressor 4. The tongue depressor 4 includes an arc-shaped tongue depressor 401. The end of the arc-shaped tongue depressor 401 extends into the retreat groove 210 and is integrally formed with an extrusion plate 402. The top of the end of the arc-shaped tongue depressor 401 is rotatably assembled in the retreat groove 210 through a rotating shaft 403. A sealing plate 404 is fixedly packaged near the opening in the retreat groove 210. A sealing silicone sleeve 405 is fixedly connected to the rear side of the sealing plate 404 for sealing the retreat groove 210, and the sealing silicone sleeve 405 is fixedly sleeved on the outer wall of the extrusion plate 402.

[0044] When the holder 2 is installed in the patient's mouth, the cannula body 5 corresponds to the tongue and is above the surface of the tongue, and the patient's tongue naturally falls between the tongue depressor 4 and the inner end of the cannula body 5, which can effectively limit the patient's tongue during use to prevent the patient's tongue from moving back and forth or generating an outward thrust on the cannula body 5 due to swallowing. In this way, the tongue will naturally rest on the arc-shaped tongue depressor 401 in the tongue depressor 4. Therefore, when the patient moves his tongue, it will not generate thrust on the cannula body 5, but will generate thrust on the arc-shaped tongue depressor 401. 01 generates a downward thrust, which can directly transfer the patient's tongue to the tongue depressor 4, and the arc-shaped tongue depressor 401 will cause the squeezing plate 402 to rotate synchronously based on the lever effect of the rotating shaft 403 after being squeezed, providing a movable space for the patient's tongue. The purpose of setting the tongue depressor 4 is to facilitate the patient to move the tongue to improve comfort, and the anti-detachment device 3 is assembled on the patient's gums, so when the patient's tongue generates a thrust on the tongue depressor 4, it can also prevent the fixator 2 from detaching from the patient's mouth, further increasing the anti-detachment property of the cannula body 5 from the fixator 2.

[0045] Embodiment 2:

[0046] During the use of Example 1, the squeezing force of the cannula body 5 is increased only by the pressure transmitted to the fixing sleeve 208 by the silicone pad 206. The cannula body 5 may be separated from the fixer 2 due to the excessive external pulling force on the cannula body 5, overcoming the friction force. At the same time, some patients may frequently move their tongues due to discomfort, or may deliberately use their tongues to push the cannula body 5. This will inevitably cause the cannula body 5 to be pushed out of the fixer 2 due to the excessive force of the patient, and there is a risk of separation under the continuous thrust. Based on this, this embodiment proposes the following improvement plan:

[0047] A pressure-bearing air bag 406 is fixedly connected to the top of the extrusion plate 402, and the top of the pressure-bearing air bag 406 is fixed to the top of the retreat groove 210. The width of the pressure-bearing air bag 406 is adapted to the size of the retreat groove 210, and the pressure-bearing air bag 406 is connected to the air cushion 209 through an air guide tube, and the air cushion 209 is connected to the supporting air bag 304 through an air supply pipe, and a pressure valve is fixedly installed on the air supply pipe.

[0048] During actual use, when the patient's tongue rests against the tongue depressor 4, a downward thrust is generated on the arc-shaped tongue depressor 401. Even when the patient's tongue presses the cannula body 5, the tongue will also simultaneously press the tongue depressor 4. In this way, the tongue depressor 4, which is continuously under pressure, can transfer part of the force of the patient's tongue to the arc-shaped tongue depressor 401. When the arc-shaped tongue depressor 401 is squeezed, based on the rotation of the rotating shaft 403, the lever action causes the squeezing plate 402 to rotate synchronously to squeeze the pressure-bearing air bag 406. In this way, the gas in the pressure-bearing air bag 406 will be introduced into the air cushion 209 through the airway tube, thereby causing the internal pressure of the air cushion 209 to increase, and then increasing the pressure of the air cushion 209 on the cannula body 5 to overcome the thrust of the patient's tongue on the cannula body 5 to push outward.

[0049] When the internal pressure of the air cushion 209 reaches the threshold of the pressure valve, the gas inside the pressure air bag 406 will continue to be input into the air cushion 209, and then the gas will be introduced into the supporting air bag 304 through the air supply pipe, causing the supporting air bag 304 to expand, and then push the first limiting plate group 301 and the second limiting plate group 302 to synchronously extend out of the fixator 2, thereby increasing the wrapping of the patient's gums, and further increasing the limiting property of the anti-detachment device 3 on the patient's gums to prevent detachment. At the same time, the extension of the first limiting plate group 301 and the second limiting plate group 302 will increase the support force on the patient's gums, and the fit to the gums will be better, but it will cause the patient to feel uncomfortable pressure, thereby reminding the patient to avoid such dangerous actions, and can increase the safety of the cannula body 5 during installation in a unique way.

[0050] When the patient continues to squeeze the tongue depressor 4 with the tongue, the arc-shaped tongue depressor 401 on the tongue depressor 4 will be further squeezed, and the gas in the pressure-bearing air bag 406 will continue to enter the air cushion 209 and then be transmitted to the supporting air bag 304. However, when the patient simultaneously uses the squeezing force of the gums to apply pressure to the anti-detachment device 3, the first limiting piece group 301 and the second limiting piece group 302 will directly apply the squeezing force to the buffer air bag 303, thereby causing the buffer air bag 303 to be squeezed. At this time, the internal pressure of the supporting air bag 304 increases. Therefore, at this time, the gas inside the supporting air bag 304 will in turn be input into the air cushion 209 through the air supply pipe, and the pressure-bearing air bag 406 will be introduced into the air cushion 209. At this time, the expansion of the air cushion 209 increases. At the same time, since the air cushion 209 is always in contact with the cannula body 5, the clamping force of the air cushion 209 on the cannula body 5 becomes larger during this process. At the same time, since the fixing sleeve 208 does not move, the driving force generated by the expansion of the air cushion 209 is used to push the cannula body 5 to move toward the deep part of the patient's oral cavity, so that the patient feels uncomfortable when the cannula body 5 is inserted. Under the premise of ensuring that the cannula body 5 will not fall off, the patient is forced to consciously and actively stop the excessive squeezing action of the tongue depressor 4 by the tongue, and the cannula body 5 can be installed quickly. At the same time, the cannula body 5 can be prevented from being detached intelligently, thereby increasing the safety of the cannula body 5.

[0051] It is worth noting that when the patient does not use the tongue to squeeze the tongue depressor 4, the gas in the pressure air bag 406, the air cushion 209 and the supporting air bag 304 will achieve self-circulation and then reach the reset state.

[0052] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
