Description

Technical Field

[0001] This invention relates to the field of medical auxiliary equipment technology, specifically to an easily adjustable endotracheal intubation positioning device for acute and critical care surgery. Background Technology

[0002] In the entire surgical process, endotracheal intubation is a crucial procedure for ensuring airway patency and maintaining respiratory function, and its effectiveness directly impacts patient safety during surgery and postoperative recovery. The core differences between critical care surgical intubation and general surgical intubation lie in the complexity of the surgical scenario, the stability of the patient's baseline physiological state, the core objective of the procedure, the aggressiveness of the technical implementation strategy, and the priority of risk control. The essence of these differences stems from the varying degrees of urgency and severity of the patient's condition, the different baseline organ function states, and the distinct core requirements for airway management in different scenarios.

[0003] In critical care settings, the primary goal is to quickly establish an effective airway and save lives, while in general surgery settings, the core focus is on ensuring surgical safety and reducing postoperative complications. However, in the clinical practice of intubation in critical care surgery, there are significant challenges in the fixation process: On the one hand, critically ill patients often experience altered consciousness and restlessness, and may require frequent changes in position during surgery. Due to the influence of facial oils, sweat secretions, and agitated movements, traditional medical tape fixation methods are prone to loosening, leading to catheter displacement or even dislodgement, directly threatening the patient's life. On the other hand, the tension of traditional fixation straps relies entirely on the experience of medical staff for adjustment, which can easily result in uneven tension.

[0004] Excessive tension may compress facial skin, causing local blood circulation disorders and leading to complications such as skin redness, swelling, and pressure sores. Insufficient tension, on the other hand, cannot achieve effective fixation and still carries the risk of catheter displacement. In addition, after the patient's position changes, traditional fixation methods require medical staff to manually readjust the fixation. In the high-intensity work scenario of emergency and critical care, this further increases the workload of medical staff and may even delay the patient's condition due to untimely adjustments. Therefore, those skilled in the art have proposed an easily adjustable emergency and critical care surgical endotracheal intubation positioning device to solve the above-mentioned technical problems. Summary of the Invention

[0013] Preferably, the elastic soothing mechanism includes a central seat, which is disposed in the middle of the inner side of the bite ring seat. A plurality of hollow elastic columns are arranged in a circular array in the middle of the outer wall of the central seat. The ends of the hollow elastic columns away from the central seat are respectively connected to the corresponding positions of the inner wall of the bite ring seat. A gap cavity is provided between the central seat and the bite ring seat. An arc-shaped biting groove is formed in the middle of the outer wall of the bite ring seat.

[0014] Working principle: When performing intubation on critically ill surgical patients, medical staff first use a laryngoscope to open the patient's mouth, then insert the endotracheal tube into the patient's body. Following this, the anti-displacement mechanism is activated. Medical staff first place a fitted mask on the patient's face, and with the assistance of an assistant, hold and secure the inserted endotracheal tube. Then, the medical staff inserts the end of the endotracheal tube through the upper positioning tube on the fitted mask and exits it. The fitted mask is then placed on the patient's face... Afterwards, medical staff adjusted the face mask to fit the patient's face according to the patient's current position. Once adjusted, the mask's bottom was secured to the patient's face using the flexible strips and elastic fitting parts. Following this adjustment, the mask was further secured around the head using upper, middle, and lower elastic bands. Velcro was also used to further secure the mask. The upper, middle, and lower elastic bands on the face mask ensure stability during use and can be adjusted to accommodate patients with different head sizes using Velcro. During the treatment of critically ill patients, tension sensors on the upper, middle, and lower elastic bands monitor the tension of each band in real time. Simultaneously, gyroscopes and accelerometers on the face mask collect real-time data on the patient's head position. When the patient's head moves, causing a change in position, if the tension of a fixing band on one side exceeds or falls below a preset range, or if the gyroscope and accelerometer detect a significant displacement, an audible and visual alarm at the corresponding position on the flexible edge strip will sound. Medical staff can then fine-tune the length of the corresponding elastic band based on the alarm position to compensate for the tension deviation caused by the change in position, ensuring the face mask always fits the face and that the relative position of the upper positioning tube insertion hole and the endotracheal tube remains unchanged, preventing tube displacement. This achieves adaptive adjustment of the trachea during the treatment of critically ill patients and prevents tracheal deviation.Simultaneously, the tracheal positioning mechanism is activated. During intubation of critically ill patients, the bottom of the endotracheal tube is positioned and fixed by a central seat on the bite ring seat around the patient's mouth. Since the central seat is located at the patient's mouth, when the patient makes slight movements, the central seat and the endotracheal tube within the guide cavity also shift synchronously with the patient's position, thus achieving positioning and fixation of the bottom of the endotracheal tube. The upper part of the endotracheal tube is initially fixed by fitting an upper positioning tube on the face mask. After the upper positioning tube completes the initial positioning, the rubber layer inside the upper positioning tube provides a further guiding and fixing effect on the endotracheal tube. When the endotracheal tube deviates during use, the rubber layer on the endotracheal tube also moves synchronously. During this displacement, the rubber diaphragm between the bite ring seat and the positioning ring seat deforms, causing the endotracheal tube, originally in the central position, to shift to another location. At this point, the elastic force at the deviated location decreases, while the elastic force at the opposite location increases. The increased size of the endotracheal tube, due to its poor elasticity, allows it to be guided by the elastic deformation and reset of its rubber diaphragm. The rubber diaphragm then drives the positioning ring and the endotracheal tube within it to achieve central reset, thus positioning and fixing the upper part of the endotracheal tube. This completes the dual positioning of the endotracheal tube during intubation. Simultaneously, the multi-modal processing mechanism is activated. When medical staff perform intubation, they connect the ventilator to the endotracheal connection port on the three-way connector. At this time, the end-expiratory carbon dioxide sensor inside the endotracheal tube collects gas signals in real time and transmits them to the display screen. The display screen shows and verifies the characteristic waveform generated by the patient. Simultaneously, medical staff connect a stethoscope through the stethoscope interface on the three-way connector, allowing them to simultaneously auscultate whether the breath sounds in both lungs are symmetrical. During intubation, the distance marker on the endotracheal tube clearly shows the insertion depth. The micro-displacement sensing module digitizes the depth data, allowing medical staff to adaptively adjust the depth of the endotracheal tube according to the actual treatment situation. This completes multi-modal synchronous processing of the patient during intubation.Simultaneously, the elastic relief mechanism activates. During surgical intubation of critically ill patients, to ensure the normal use and patency of the endotracheal tube, a bite ring is used to support the inside of the patient's mouth. During this support, the patient's tooth crowns bite into the arc-shaped occlusal groove of the bite ring. Simultaneously, the arc-shaped occlusal groove also fixes the bite ring inside the patient's mouth. With prolonged mouth opening, the patient's upper and lower jaws need to bite to relieve the soreness caused by prolonged mouth opening. Therefore, during the biting movement of the patient's upper and lower jaws, the bite ring... As the jaw ring moves inward, the space between the jaws also shrinks. This inward movement and shrinking space cause a corresponding volume change in the hollow elastic column between the jaw ring and the lower positioning tube. Subsequently, as the patient's jaw occlusion weakens or disappears, the hollow elastic column simultaneously supports the space between the jaws and the jaw ring, allowing them to return to their original position. This ensures normal treatment during endotracheal intubation, thus providing elastic relief to the jaw in critically ill patients undergoing endotracheal intubation.

[0015] This invention provides an easily adjustable endotracheal intubation positioning device for emergency and critical care surgery. It offers the following advantages: 1. This invention, by adding and setting an adaptive anti-displacement mechanism, allows the mask to fit snugly against the patient's face during intubation in critically ill patients. This improves the sealing and comfort of the mask through the cooperation of flexible side strips and elastic fitting parts. At the same time, multiple elastic bands at different positions provide multi-directional head-wrap fixation. Combined with Velcro connections, this not only adapts to the personalized needs of patients with different head circumferences but also ensures fixation stability. On the other hand, tension sensors monitor the tension of the elastic bands in real time, and gyroscopes and accelerometers capture changes in body position. With corresponding audible and visual alarms, it can promptly warn of abnormal tension or body displacement risks, facilitating precise fine-tuning by medical staff and preventing catheter displacement and dislodgement. This not only ensures the safety of the patient's airway but also reduces the workload of frequent manual checks.

[0016] 2. By adding and setting a tracheal positioning mechanism, this invention can not only position the bottom of the tracheal tube by connecting the guide cavity of the lower positioning tube with the central seat of the bite ring seat during intubation treatment of critically ill patients, and fix the bottom of the tube by means of the patient's oral occlusion to prevent the lower end of the tube from shifting, but also the rubber layer in the upper positioning tube can guide and fix the upper part of the tube. In conjunction with the elastic rubber diaphragm between the ring seat and the positioning ring seat, when the tube shifts, the elastic force difference generated by the elastic deformation can guide the tube to automatically return to the center, realizing dual positioning of the tube from top to bottom, ensuring that the tube is always in the correct ventilation position, avoiding the impact of displacement on the ventilation effect, and improving the safety and reliability of intubation treatment.

[0017] 3. By adding and setting a multi-modal processing mechanism, this invention allows medical staff to simultaneously auscultate both lungs and quickly determine the symmetry of breath sounds during intubation of critically ill patients. First, the mechanism uses a dual-path auscultation tube and endotracheal tube set in parallel, along with a stethoscope interface on a three-way connector, to simultaneously auscultate breath sounds of both lungs. Second, the end-expiratory carbon dioxide sensor can collect gas signals in real time and generate characteristic waveforms to accurately verify the intubation position. At the same time, the distance marker on the endotracheal tube can clearly show the insertion depth, assisting medical staff in adjusting the depth. The multi-modal monitoring function works in tandem, eliminating the need to switch between multiple devices, which improves positioning accuracy and simplifies the operation process, meeting the core needs of rapid resuscitation of critically ill patients.

[0018] 4. By adding and setting an elastic relief mechanism, this invention not only enables stable occlusion of the patient's tooth crowns through the arc-shaped occlusal groove of the bite ring seat during intubation treatment of critically ill patients, fixing the position of the bite ring seat in the oral cavity and ensuring the patency of the endotracheal tube, but also provides cushioning when the patient's upper and lower jaws move during occlusion, relieving the soreness of the jaw caused by prolonged mouth opening. At the same time, the space cavity provides space for the movement of the bite ring seat, avoiding displacement of the bite ring seat or compression of oral tissues due to the patient's jaw movement, improving the patient's comfort during intubation treatment and ensuring the smooth progress of treatment.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 -Appendix Figure 2 This invention provides an easily adjustable endotracheal intubation positioning device for critical care surgery, including a face mask 1. An endotracheal tube 7 for endotracheal intubation treatment of critically ill patients is disposed inside the face mask 1, and one end of the endotracheal tube 7 passes through the corresponding position of the face mask 1 and extends outward. A mouth ring seat 14 for supporting and fixing the mouth of critically ill patients is disposed inside the face mask 1. Please see the appendix Figure 3 -Appendix Figure 5 An anti-displacement mechanism is provided at the bottom of the fitted mask 1 to prevent tracheal displacement caused by changes in body position during intubation treatment in critically ill patients. The adaptive anti-movement mechanism includes a flexible edge strip 2. The flexible edge strip 2 is provided at the bottom edge of the face mask 1. The bottom of the flexible edge strip 2 is provided at the elastic fitting part 30 for fitting the patient's face. An upper positioning tube 9 is provided on one side of the middle part of the top of the face mask 1.

[0023] When the adaptive anti-movement mechanism is activated, medical staff first place the face mask 1 on the patient's face and, with the assistance of an assistant, hold and fix the endotracheal tube 7 inserted into the patient's body. Then, the medical staff pass the end of the endotracheal tube 7 through the upper positioning tube 9 on the face mask 1 and exit it. After the medical staff places the face mask 1 on the patient's face, they make adaptive adjustments to the face mask 1 according to the current position of the patient. After the face mask 1 is adjusted, the medical staff use the flexible edge strip 2 and elastic fitting part 30 at the bottom of the face mask 1 to make the bottom of the face mask 1 fit the corresponding position on the patient's face.

[0024] The anti-slip mechanism also includes audible and visual alarms 4. Multiple audible and visual alarms 4 are equidistantly arranged on both sides of the outer wall of the flexible edge strip 2. Upper elastic bands 3 are arranged on both sides of the front middle part of the bottom end of the flexible edge strip 2. Middle elastic bands 21 are arranged on both sides of the middle part of the bottom end of the flexible edge strip 2. Lower elastic bands 22 are arranged on both sides of the rear middle part of the bottom end of the flexible edge strip 2. The ends of the upper elastic bands 3, middle elastic bands 21 and lower elastic bands 22 are connected by Velcro 5. The upper elastic bands 3, middle elastic bands 21 and lower elastic bands 22 correspond to the positions of the audible and visual alarms 4 on the flexible edge strip 2.

[0025] After the medical staff made the necessary adjustments to the face mask 1, they used the upper elastic band 3, the middle elastic band 21, and the lower elastic band 22 to fix the face mask 1 around the upper, middle, and lower parts of the head. At the same time, the Velcro 5 not only ensured the stability of the upper elastic band 3, the middle elastic band 21, and the lower elastic band 22 on the face mask 1 during use, but also allowed for adaptive adjustments for patients with different head sizes.

[0026] The adaptive anti-movement mechanism also includes a tension sensor 13. Tension sensors 13 are installed in the middle of the outer walls of the upper elastic band 3, the middle elastic band 21 and the lower elastic band 22 to monitor the tension during use. A gyroscope 15 and an acceleration sensor 16 are respectively installed in the middle of one side of the inner wall of the face mask 1 to monitor the patient's head position change data.

[0027] During the treatment of critically ill patients, tension sensors 13 on the upper elastic band 3, the middle elastic band 21 and the lower elastic band 22 monitor the tension value data of each elastic band in real time. At the same time, the gyroscope 15 and the accelerometer 16 on the face mask 1 collect the patient's head position data in real time.

[0028] When the patient's head moves, causing a change in body position, if the tension of the fixation strap on one side exceeds or falls below the preset range, or if the gyroscope 15 and accelerometer 16 detect a large displacement, the audible and visual alarm 4 at the corresponding position on the flexible edge strip 2 will trigger an audible and visual alarm at the corresponding position. At this time, medical staff can fine-tune the length of the corresponding elastic strap according to the alarm position of the audible and visual alarm 4 to compensate for the tension deviation caused by the change in body position, ensuring that the face mask 1 always fits the face and that the relative position of the upper positioning tube 9 insertion hole and the tracheal tube 7 remains unchanged, thus avoiding tube displacement. This completes the adaptive adjustment of the trachea for critically ill patients during treatment and prevents tracheal deviation.

[0029] Please see the appendix Figure 8 -Appendix Figure 9 The tracheal positioning mechanism is mounted on the fitted mask 1 and is used to perform multiple positioning and fixation of the trachea of ​​critically ill patients during treatment. The tracheal positioning mechanism includes a lower positioning tube 20, a lower positioning tube 20 is provided in the middle of the inner side of the bite ring seat 14, a guide cavity 24 is provided on the inner wall of the lower positioning tube 20, an annular seat 27 is provided on the inner wall of the upper positioning tube 9, a positioning ring seat 28 is provided in the middle of the inner side of the annular seat 27, a rubber layer 29 is provided on the inner wall of the positioning ring seat 28, and an elastically resettable rubber diaphragm 26 is provided between the positioning ring seat 28 and the annular seat 27.

[0030] When the tracheal positioning mechanism is activated, during the intubation treatment of critically ill patients, the bottom of the tracheal tube 7 is positioned and fixed by the central seat 23 that bites into the bite ring seat 14 of the patient's mouth. Since the central seat 23 is located at the patient's mouth, when the patient makes some small displacement movements, the central seat 23 at the patient's mouth and the tracheal tube 7 in the guide cavity 24 will also move synchronously with the patient's body position, thereby achieving the positioning and fixation of the bottom of the tracheal tube 7.

[0031] The upper part of the endotracheal tube 7 is initially fixed by the upper positioning tube 9 on the mask 1. After the upper positioning tube 9 completes the initial positioning, the rubber layer 29 inside the upper positioning tube 9 provides a second guiding fixation for the endotracheal tube 7. When the endotracheal tube 7 shifts during use, the rubber layer 29 on the endotracheal tube 7 will also move synchronously.

[0032] During its displacement, the rubber diaphragm 26 between the annular seat 27 and the positioning ring seat 28 deforms due to the displacement, causing the endotracheal tube 7, which was originally in the center position, to shift to another position. At this time, the elastic force corresponding to the shifted position of the endotracheal tube 7 will decrease, while the elastic force at the opposite position will increase. Therefore, guided by the difference in elastic force, the endotracheal tube 7 is guided by the elastic deformation and reset of the rubber diaphragm 26. The rubber diaphragm 26 will then drive the positioning ring seat 28 and the endotracheal tube 7 inside it to reset to the center, thereby achieving the positioning and fixation of the upper part of the endotracheal tube 7, thus completing the dual positioning treatment of the endotracheal tube 7 during intubation treatment.

[0033] Please see the appendix Figure 6 - Appendix Figure 7 The multimodal processing mechanism, which is installed on the endotracheal tube 7, is used to perform simultaneous multimodal treatment and diagnostic processing on critically ill patients during endotracheal intubation. The multi-mode processing mechanism includes a dual-path auscultation catheter 6. The middle of both sides of the endotracheal tube 7 is provided with dual-path auscultation catheters 6 corresponding to the patient's two lung regions. The top of the outer wall of the endotracheal tube 7 is provided with a distance mark 8 indicating the insertion depth. The end-expiratory carbon dioxide sensor 17 is provided inside the endotracheal tube 7 at a position away from the face mask 1.

[0034] When the multi-mode processing unit is activated, while medical staff are performing intubation on the patient, they connect the ventilator to the endotracheal connection port 11 on the three-way connector 10. At this time, the end-expiratory carbon dioxide sensor 17 in the endotracheal tube 7 collects gas signals in real time and transmits them to the display screen. The display screen displays and verifies the characteristic waveform generated by the patient. At the same time, medical staff connect a stethoscope through the stethoscope interface 12 on the three-way connector 10, and can simultaneously auscultate whether the breath sounds of both lungs are symmetrical.

[0035] The multi-mode processing mechanism also includes a three-way interface seat 10. The upper part of the face mask 1 is provided with a three-way interface seat 10. The ends of the endotracheal tube 7 and the dual-path auscultation tube 6 are connected to the interior of the three-way interface seat 10. The top center of the three-way interface seat 10 is provided with an endotracheal connection port 11. The middle of both sides of the three-way interface seat 10 are provided with stethoscope interfaces 12.

[0036] Meanwhile, during intubation, the distance marker 8 on the endotracheal tube 7 can clearly show the insertion depth of the tube. The micro displacement sensing module digitizes the depth data, and medical staff can make adaptive depth adjustments to the endotracheal tube 7 in the patient's body according to the actual treatment situation, thereby completing multimodal synchronous processing of the patient during intubation.

[0037] Please see the appendix Figure 8The elastic relaxation mechanism, which is set on the jaw ring seat 14, is used to provide elastic relaxation to the jaw of critically ill patients during endotracheal intubation.

[0038] The elastic soothing mechanism includes a central seat 23. The central seat 23 is located in the middle of the inner side of the bite ring seat 14. A plurality of hollow elastic columns 19 are arranged in a circular array in the middle of the outer wall of the central seat 23. The ends of the hollow elastic columns 19 away from the central seat 23 are respectively connected to the corresponding positions of the inner wall of the bite ring seat 14. A gap cavity 25 is provided between the central seat 23 and the bite ring seat 14. An arc-shaped biting groove 18 is opened in the middle of the outer wall of the bite ring seat 14.

[0039] When the elastic relief mechanism is activated, during surgical intubation of critically ill patients, in order to ensure the normal use and patency of the endotracheal tube 7, the bite ring seat 14 is used to support the inside of the patient's oral cavity. When it is supported, the patient's tooth crowns will bite onto the arc-shaped occlusal groove 18 of the bite ring seat 14, and the bite ring seat 14 inside the patient's oral cavity can also be fixed by the arc-shaped occlusal groove 18.

[0040] With prolonged mouth opening, the patient's upper and lower jaws need to bite to relieve the soreness caused by prolonged mouth opening. Therefore, during the process of the patient's upper and lower jaws biting and moving, the corresponding position of the bite ring seat 14 moves inward, and the gap of the interspace cavity 25 also narrows as the bite ring seat 14 moves.

[0041] At this time, as the bite ring seat 14 moves inward and the space of the gap cavity 25 shrinks, the hollow elastic column 19 between the bite ring seat 14 and the lower positioning tube 20 will also undergo corresponding volume changes. Subsequently, as the patient's upper and lower jaw biting force weakens and disappears, the hollow elastic column 19 will also support the gap cavity 25 and the bite ring seat 14 to reset, thereby ensuring the patient's normal treatment during endotracheal intubation and thus completing the elastic relaxation treatment of the jaw during endotracheal intubation for critically ill patients.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
