Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to an intelligent anesthesia tracheal intubation device. Background Art

[0002] Anesthesia tracheal intubation, as a core technology in modern anesthesiology and critical care medicine, has developed quite maturely and is widely used in fields such as surgical anesthesia, emergency resuscitation, and intensive care. Tracheal intubation technology mainly relies on the assistance of a laryngoscope. By directly or indirectly visualizing the glottic structure, the tracheal catheter is accurately inserted into the patient's trachea to ensure airway patency and provide effective mechanical ventilation support. The traditional laryngoscope intubation technique is the most widely used method in clinical practice. The operator uses a laryngeal blade to lift the epiglottis and inserts the catheter after exposing the glottis. In recent years, with the progress of medical technology, video laryngoscopes have gradually become popular. They provide a clearer view of the glottis through a high-definition camera and a display screen, significantly improving the success rate of intubation, especially showing obvious advantages in the management of difficult airways. In terms of drugs, fast-acting anesthetic drugs and muscle relaxants are often used in modern anesthesia to optimize intubation conditions and reduce the discomfort of patients. Despite the significant progress made in the existing technology, intubation still has certain risks, such as intubation failure, misinsertion into the esophagus, or airway injury.

[0003] In the prior art, the patent publication number CN118105590B discloses an automatic laryngoscope intubation system. Through multiple image acquisition modules, images from the patient's body position to the face and then to the oral and pharyngeal regions are established, and an automatic intubation is completed using a robotic arm through image recognition technology. However, the intubation often does not smoothly enter the glottis, and the patient may experience situations such as difficult glottis visualization, cysts, etc. When performing intubation, a stylet is often used to enhance the rigidity of the trachea, making it easier for the trachea to push open the glottis and reducing the insertion difficulty. After the trachea is inserted into the glottis, the stylet is withdrawn so that the trachea can penetrate deeper along the patient's respiratory tract. In addition, after the trachea enters the glottis, depending on the different respiratory secretions of the patient, it may cause complications such as respiratory mucosa damage and bleeding. Summary of the Invention

[0004] To solve the above problems, the present invention provides an intelligent anesthesia tracheal intubation device for reducing patient complications and the operation difficulty of users through intelligent assistance.

[0005] To achieve the above object, the technical solution of the present invention is as follows: An intelligent anesthesia tracheal intubation device includes a bracket, and a controller is provided on the bracket;

[0006] It further includes a flexible trachea, and a stylet is slidably connected inside the flexible trachea. The stylet includes several unit segments that are frictionally hinged to each other. Electromagnets are provided at the friction hinge joints of the unit segments, and the electromagnets are used to change the frictional hinge pressure to control the rotational damping of the hinge;

[0007] A trachea pusher and a stylet pusher are fixedly connected to the bracket. The trachea pusher is used to drive the flexible trachea to penetrate into and retract from the patient's respiratory tract, and the stylet pusher is used to drive the stylet to penetrate into and retract from the patient's respiratory tract;

[0008] The controller is also used to judge the resistance value when the flexible trachea penetrates into the patient's respiratory tract by monitoring the driving load power of the trachea pusher; the controller is used to compare the resistance value with a preset value. When the resistance value is greater than the preset value, the voltage of the electromagnet is reduced to reduce the friction hinge damping.

[0009] The following beneficial effects can be obtained by adopting the above scheme:

[0010] 1. In this scheme, the user needs to independently complete the operation of lifting the epiglottis with the laryngoscope blade. After inserting the flexible trachea into the glottis, the controller is started. The controller will automatically penetrate the flexible trachea into the patient's respiratory tract without manual operation by the physician, reducing the working intensity of the physician. And by monitoring the driving load power, the resistance of penetration is judged, and the friction hinge damping is adjusted by the electromagnet to reduce the negative impacts brought by friction and collision during the penetration of the flexible trachea, so as to reduce complications such as respiratory mucosa injury and bleeding.

[0011] 2. In this scheme, the softness of the flexible trachea can be lower than that of a conventional trachea, enabling it to have stronger adaptability. The stylet changes the friction hinge damping by lifting its contact pressure, thereby changing the rigidity of the flexible trachea during use, so that the deflection change of the flexible trachea can always keep the flexible trachea with sufficient rigidity to push open the respiratory tract secretions and maintain sufficient flexibility to adapt to the curvature of the respiratory tract. In addition, since the stylet can change its own friction hinge damping, during the penetration of the flexible trachea, it is not necessary to pull it out. After confirming the final position of the flexible trachea, it is then pulled out and the flexible trachea is connected to the anesthesia machine.

[0012] Furthermore, a stethoscope is also included. The stethoscope includes a plurality of audio acquisition nodes, and the audio acquisition nodes are used to acquire the audio of each region of the patient's chest;

[0013] The stylet also includes a flexible test tube, and each unit segment is fixedly connected to the flexible test tube.

[0014] Beneficial effect: After the flexible trachea penetrates into the patient's respiratory tract, it is necessary to determine whether the air outlet position is in the bronchus. The stethoscope can deploy a plurality of audio acquisition nodes on the patient's chest, so that after injecting air into the flexible test tube, it can judge whether the position of the flexible trachea is appropriate by the airflow sound collected. When performing the airflow injection test, it is usually necessary to fix the position of the flexible trachea. At this time, the voltage of the electromagnet can be increased to fix the position of the flexible trachea by increasing the friction hinge damping, so as to reduce the change in the position of the flexible trachea generated when injecting air.

[0015] Further, one end of the flexible trachea that extends into the patient's respiratory tract is provided with an airbag cuff, and the end of the flexible trachea away from the airbag cuff is provided with an injection tube, and the injection tube is communicated with the airbag cuff.

[0016] Beneficial effects: Although the tube core can fix the position of the flexible trachea during the injection air flow test, after the tube core is pulled out subsequently, the position of the flexible trachea may still change. The airbag cuff can expand after injecting gas, so that the flexible trachea is clamped in the patient's respiratory tract, so as to stabilize the position of the flexible trachea after the tube core is pulled out.

[0017] Further, an air pump is fixedly connected to the bracket, and the air pump is communicated with the flexible test tube;

[0018] The controller is used to control the air pump to inject air into the patient's lungs through the flexible test tube after the tracheal pusher drives the flexible trachea to penetrate into the patient's respiratory tract by a preset distance. When the audio acquisition node does not collect air flow sounds at the positions of the left and right lungs of the patient's chest, the tracheal pusher and the tube core pusher respectively drive the flexible trachea and the tube core to retreat by a preset distance value, and the controller controls the air pump to inject air into the patient's lungs again and collect the air flow sounds through the audio acquisition node.

[0019] Beneficial effects: The air pump can replace the doctor to perform the injection air flow test. When the injection air flow test fails to collect air flow sounds at the positions of the left and right lungs of the patient's chest, it means that the flexible trachea has been inserted into the patient's bronchus. Therefore, the flexible trachea needs to be retracted a certain distance to ensure that the subsequent anesthesia process can effectively inject the left and right lungs of the patient. When the flexible trachea is retracted, the injection air flow test is continued until the retraction distance meets the anesthesia requirements.

[0020] Further, the controller is used to increase the voltage of the electromagnet and increase the friction hinge damping when the air pump injects air into the patient's lungs through the flexible test tube.

[0021] Beneficial effects: During the injection air flow test, it is necessary to keep the position of the flexible trachea stable. By increasing the voltage of the electromagnet and increasing the friction hinge damping, the position of the flexible trachea during the air flow test can be kept stable.

[0022] Further, the air pump is communicated with the injection tube, and the controller is further used to control the air pump to inject air into the airbag cuff through the injection tube when the audio acquisition node collects air flow sounds at the positions of the left and right lungs of the patient's chest.

[0023] Beneficial effects: When the audio acquisition node collects air flow sounds at the positions of the left and right lungs of the patient's chest, it means that the position of the flexible trachea is appropriate. At this time, air can be injected into the airbag cuff through the injection tube to fix the position of the flexible trachea.

[0024] Further, the controller is also used to cut off the power supply of the electromagnet after the inflation of the airbag cuff is completed, and control the core pusher to withdraw the core from the flexible trachea.

[0025] Beneficial effects: After the inflation of the airbag cuff, the position of the flexible trachea has been fixed. By removing the core, the original space inside the flexible trachea can be restored, and the anesthesia machine can be connected to perform anesthesia operations.

[0026] Further, an adapter block is detachably connected to the core.

[0027] Beneficial effects: Under normal circumstances, flexible tracheas are disposable, and the thicknesses of flexible tracheas used by patients of different ages and body types are different. Since the core is equipped with multiple micro-electromagnets and has a relatively high manufacturing cost, by detachably connecting the adapter block, the thickness of the core can be changed by disassembly to adapt to flexible tracheas of different thicknesses. At the same time, the core does not come into contact with the patient's respiratory tract, so the degree of contamination is low and it can be reused after disinfection.

[0028] Further, the trachea pusher is a cylinder, and a fixing buckle is provided on the output shaft of the trachea pusher for fixing the flexible trachea. The core pusher includes a friction roller set and a motor, and the motor is used to drive the friction roller set to rotate.

[0029] Beneficial effects: The cylinder can drive the penetration and retraction of the flexible trachea through expansion and contraction, and complete the fixation with the flexible trachea through the fixing buckle. The friction roller set can rotate the friction rollers, so as to control the penetration and retraction of the core by using the frictional force. Since the outer surface of the flexible trachea needs to have a certain lubricity to facilitate reducing the penetration difficulty and its friction coefficient is small, it is difficult to drive by the friction roller set, so the form of the cylinder is adopted.

[0030] Further, the controller is also provided with two modes of overall control and local control for controlling the voltage reduction of the electromagnet. Among them, the overall control is used to control the voltage of all electromagnets to decrease simultaneously, and the local control decreases the voltage of the electromagnets of each unit section separately until the resistance value decreases to the preset range.

[0031] Beneficial effects: Since the core is composed of multiple unit sections hinged together, two modes can be adopted in the control of the electromagnet. The overall control mode has a faster friction hinge damping simulation and can quickly respond to the resistance process. However, since its rigidity decreases as a whole, it is difficult to maintain a suitable rigid structure after encountering resistance, and thus the penetration speed will also be affected.

[0032] In the local control mode, the rigidity of the resistance can be changed each time after encountering resistance, which makes the reaction speed slower. However, since the overall rigid structure is maintained well, the penetration speed can also be maintained at a good level.

[0033] Additional aspects and advantages of the present invention will be given in part in the following description, become apparent in part from the following description, or be learned by practice of the present invention. Brief Description of the Drawings

[0042] The following is a further detailed description through specific embodiments:

[0043] Embodiment 1:

[0044] As shown in the Figures 1-4 accompanying figure: An intelligent anesthesia tracheal intubation device includes a bracket 1, and a controller (not shown in the figure) is bolted to the bracket 1.

[0045] It further includes a flexible trachea 2, and a tube core 3 is slidably connected inside the flexible trachea 2. The tube core 3 includes a number of unit segments 4 that are frictionally hinged to each other. Electromagnets 5 are installed at the friction hinge joints of the unit segments 4. The electromagnets 5 are micro electromagnets 5. The suction force of the electromagnets 5 is selected to be 0.05 - 0.1 kg, the diameter is 4 mm - 6 mm, and the thickness is 3 - 4 mm. Since the suction force requirement of the electromagnets 5 is small, miniaturization can be achieved by reducing the number of turns and the diameter of the coils of the electromagnets 5. The electromagnets 5 are used to change the frictional hinge pressure to control the rotational damping of the hinge.

[0046] A trachea pusher 6 and a tube core pusher 7 are screwed to the bracket 1. The trachea pusher 6 is used to drive the flexible trachea 2 to penetrate into and retract from the patient's respiratory tract, and the tube core pusher 7 is used to drive the tube core 3 to penetrate into and retract. The trachea pusher 6 is a cylinder, and a fixing buckle 12 is provided on the output shaft of the cylinder. The fixing buckle 12 is used to fix the flexible trachea 2. The tube core pushers 7 are all friction roller sets, and each friction roller set is provided with a motor for driving the friction roller to rotate.

[0047] The trachea pusher 6 is also used to judge the resistance value when the flexible trachea 2 penetrates into the patient's respiratory tract by listening to the driving load power; the controller is used to obtain the resistance value, and when the resistance value is greater than the preset value, the voltage of the electromagnet 5 is reduced to reduce the frictional hinge damping.

[0048] It further includes a stethoscope, and the stethoscope includes a number of audio acquisition nodes, which are used to collect the audio of each area of the patient's chest; the tube core 3 further includes a flexible test tube 8, and the unit segments 4 are all bonded to the flexible test tube 8.

[0049] One end of the flexible trachea 2 that penetrates into the patient's respiratory tract is provided with an airbag cuff 9, and the other end of the flexible trachea 2 away from the airbag cuff 9 is provided with an injection tube, and the injection tube is communicated with the airbag cuff 9.

[0050] On the bracket 1, there is an air pump 10, and the air pump 10 is communicated with the flexible test tube 8; the controller is used to control the air pump 10 to inject air into the patient's lungs through the flexible test tube 8 after the tracheal thruster 6 drives the trachea to penetrate into the patient's respiratory tract by a preset distance value. When the airflow sound is not collected at the positions of the left and right lungs of the patient's chest by the audio acquisition node, the tracheal thruster 6 and the tube core thruster 7 respectively drive the flexible trachea 2 and the tube core 3 to retreat by a preset distance value, and the controller controls the air pump 10 to inject air into the patient's lungs again and collect the airflow sound through the audio acquisition node.

[0051] The air pump 10 is communicated with the injection tube. When the airflow sound is collected at the positions of the left and right lungs of the patient's chest by the audio acquisition node, the controller controls the air pump 10 to inject air into the balloon cuff 9 through the injection tube.

[0052] Before use, deploy the bracket 1 around the patient, and the bracket 1 can be fixed to the operating bed so that when performing anesthesia operations, it is convenient to take and use the flexible trachea 2. The user needs to independently complete the operation of lifting the epiglottis with the laryngoscope. After inserting the flexible trachea 2 into the glottis, start the controller, and the controller will automatically penetrate the flexible trachea 2 into the patient's respiratory tract without manual operation by the physician, reducing the work intensity of the physician. And by monitoring the driving load power, judge the resistance of penetration, and adjust the friction hinge damping through the electromagnet 5 to reduce the negative effects brought by friction and collision during the penetration of the flexible trachea 2, so as to reduce complications such as respiratory mucosa injury and bleeding.

[0053] The softness of the flexible trachea 2 can be lower than that of a conventional trachea, so that it can have stronger adaptability. The tube core 3 changes the friction hinge damping by lifting its contact pressure, thereby changing the rigidity of the flexible trachea 2 during use, so that the deflection change of the flexible trachea 2 can make the flexible trachea 2 always maintain sufficient rigidity to push open the respiratory tract secretions and maintain sufficient flexibility to adapt to the curvature of the respiratory tract. When inserting the flexible trachea 2 into the glottis, the friction hinge damping will be adjusted to a large value through the electromagnet 5 to facilitate insertion into the glottis. In addition, since the tube core 3 can change its own friction hinge damping, during the penetration of the flexible trachea 2, it is not necessary to pull it out. After confirming the final position of the flexible trachea 2, then pull it out and connect the flexible trachea 2 to the anesthesia machine.

[0054] After the flexible trachea 2 penetrates into the patient's respiratory tract, it is necessary to determine whether the air outlet position is in the bronchus. The stethoscope can deploy multiple audio acquisition nodes on the patient's chest, so that after injecting air into the flexible test tube 8, it can judge whether the position of the flexible trachea 2 is appropriate through the collected airflow sound. When performing the air injection test, it is usually necessary to fix the position of the flexible trachea 2. At this time, the voltage of the electromagnet 5 can be increased, and the friction hinge damping can be increased to fix the position of the flexible trachea 2 to reduce the change in the position of the flexible trachea 2 generated when injecting air.

[0055] Although the core 3 can fix the position of the flexible tracheal tube 2 during the injection air flow test, after the core 3 is pulled out subsequently, the position of the flexible tracheal tube 2 may still change. The airbag cuff 9 can expand after injecting gas, so that the flexible tracheal tube 2 is clamped in the patient's respiratory tract, in order to stabilize the position of the flexible tracheal tube 2 after the core 3 is pulled out.

[0056] The air pump 10 can replace the doctor to conduct the injection air flow test. When the injection air flow test fails to collect the air flow sound at both the left and right lung positions of the patient's chest, it indicates that the flexible tracheal tube 2 has been inserted into the patient's bronchus. Therefore, the flexible tracheal tube 2 needs to be retracted a certain distance to ensure that the subsequent anesthesia process can effectively inject the patient's left and right lungs. When the flexible tracheal tube 2 is retracted, the injection air flow test is continued until the retraction distance meets the anesthesia requirements.

[0057] The controller is used to increase the voltage of the electromagnet 5 and increase the friction hinge damping when the air pump 10 injects air into the patient's lungs through the flexible test tube 8.

[0058] When conducting the injection air flow test, it is necessary to keep the position of the flexible tracheal tube 2 stable. By increasing the voltage of the electromagnet 5 and increasing the friction hinge damping, the position of the flexible tracheal tube 2 can be kept stable during the air flow test.

[0059] The air pump 10 is connected to the injection tube. When the audio acquisition node collects the air flow sound at both the left and right lung positions of the patient's chest, the controller controls the air pump 10 to inject air into the airbag cuff 9 through the injection tube.

[0060] When the audio acquisition node collects the air flow sound at both the left and right lung positions of the patient's chest, it indicates that the position of the flexible tracheal tube 2 is appropriate. At this time, air can be injected into the airbag cuff 9 through the injection tube to fix the position of the flexible tracheal tube 2.

[0061] After the airbag cuff 9 is inflated, the controller cuts off the power supply of the electromagnet 5 and controls the core pusher 7 to withdraw the core 3 from the flexible tracheal tube 2.

[0062] After the airbag cuff 9 is inflated, the position of the flexible tracheal tube 2 has been fixed. The core 3 can be taken out to restore the original space in the flexible tracheal tube 2 and connect the anesthesia machine for anesthesia operation.

[0063] Embodiment 2:

[0064] The difference from the above embodiment is that the adapter blocks 11 are detachably connected to the core 3.

[0065] The specific implementation process is as follows: Under normal circumstances, the flexible trachea 2 is for single use, and the thickness of the flexible trachea 2 used by patients of different ages and body types is different. Since the tube core 3 is equipped with multiple micro-electromagnets 5 and the manufacturing cost is relatively high, an adapter block 11 is detachably connected, so that the thickness of the tube core 3 can be changed and adjusted before the operation to adapt to different flexible tracheas 2. At the same time, the tube core 3 does not contact the side wall of the patient's respiratory tract, so the degree of contamination is low and it can be reused after disinfection.

[0066] Embodiment 3:

[0067] The difference from the above embodiment is that when the controller reduces the voltage of the electromagnet 5, there are two modes: overall control and local control. Among them, overall control means that the voltage of all electromagnets 5 is reduced, and local control means that the voltage of the electromagnet 5 of each unit segment is reduced separately until the resistance value is reduced to the preset range.

[0068] Since the tube core 3 is composed of multiple unit segments 4 hinged together, two modes can be adopted in the control of the electromagnet 5. The overall control mode has a faster friction hinge damping simulation and can quickly respond to the resistance process. However, since its rigidity decreases as a whole, it is difficult to maintain a suitable rigid structure after encountering resistance, and thus the penetration speed will also be affected.

[0069] In the local control mode, the rigidity of the resistance encountered can be changed each time resistance is encountered, making the reaction speed slower. However, since the overall rigid structure is well maintained, the penetration speed can also be kept at a good level.

[0070] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
