Description

Technical Field

[0001] This invention relates to the medical field, specifically to a nursing device with temperature and humidity monitoring function. Background Technology

[0002] In intensive care nursing, endotracheal intubation and mechanical ventilation are common methods for maintaining the vital signs of critically ill patients. Whether the temperature and humidity of the airway are suitable directly affects the patient's airway mucosal defense function, ciliary clearance ability, and secretion characteristics, and is one of the important indicators for evaluating nursing quality.

[0003] Currently, most clinically used endotracheal intubation devices lack real-time temperature and humidity monitoring capabilities. Chinese Patent Publication No. CN222854389U proposes an endotracheal intubation device that improves the interception of secretions through a dual-bag structure. However, this design lacks integrated temperature and humidity sensors. Nurses cannot directly obtain real-time temperature and humidity parameters within the airway during care and can only rely on the settings of the ventilator's built-in humidifier for indirect assessment. This blind spot can lead to nursing complications such as dry airway mucosa, thick and difficult-to-suction sputum, and even sputum crust formation that obstructs the airway, increasing the risk of unplanned extubation and ventilator-associated pneumonia.

[0004] Based on this, the present invention designs a nursing device with temperature and humidity monitoring function, which aims to provide nursing staff with intuitive and reliable airway internal environment data, thereby improving the accuracy and safety of airway care. Summary of the Invention

[0005] The present invention addresses the aforementioned deficiencies in existing technologies by providing a nursing device with temperature and humidity monitoring functionality. The device includes a trachea body, with two parallel airbags fixedly mounted on its outer front end. An L-shaped mounting groove is provided at the lower front end of the trachea body. A limiting groove is provided at the inner end of the L-shaped mounting groove away from the inner wall of the trachea body. A receiving groove, communicating with the L-shaped mounting groove, is provided at the middle of the front end of the L-shaped mounting groove. A vertical through hole, communicating with the receiving groove, is provided at the middle of the front end of the receiving groove, with the front end of the vertical through hole penetrating the trachea body. The inner diameter of the receiving groove is larger than the inner diameter of the vertical through hole. The device also includes:

[0006] The sensor mounting mechanism is installed in an L-shaped mounting slot and houses a temperature and humidity sensor. This mechanism secures the sensor to the inner end of the trachea body, ensuring the monitoring point is close to the core airflow of the airway. A fixing mechanism is installed in a storage slot and a vertical through-hole. This mechanism positions the sensor mounting mechanism to prevent it from dislodging, ensuring the sensor does not shift during suctioning, turning, or other nursing procedures.

[0007] In one embodiment, an externally threaded mounting cylinder is fixedly installed at the front end of the trachea body, and a sealing cap is installed on the outer thread of the externally threaded mounting cylinder. A protective net is fixedly embedded at the front end of the sealing cap, which facilitates the disassembly, cleaning or replacement of the sensor by nursing staff, and at the same time prevents airway secretions from clogging the detection head.

[0008] In one embodiment, a wire is fixedly installed on the inner wall of the trachea body, and the wire is distributed in a spiral shape on the inner side of the trachea body to avoid the wire being pulled and damaged during the suctioning operation, while not affecting the effective ventilation cross-sectional area of ​​the airway.

[0009] In one embodiment, the sensor mounting mechanism includes a mounting plate inserted into an L-shaped mounting groove. A rectangular limiting frame is fixedly mounted on the lower outer side of the mounting plate. The rectangular limiting frame is inserted into a limiting groove via a sliding connection. The shape of the mounting plate matches the L-shaped mounting groove, and the shape of the rectangular limiting frame matches the limiting groove. Both the mounting plate and the rectangular limiting frame are arc-shaped, and the curvature of the mounting plate and the rectangular limiting frame matches the arc shape of the inner wall of the trachea, ensuring that the sensor fits snugly against the inner wall of the airway, reducing irritation to the mucosa and improving nursing comfort.

[0010] In one embodiment, the temperature and humidity sensor is fixedly embedded in the middle of the upper part of the mounting plate, and a detection head is fixedly installed in the middle of the front end of the temperature and humidity sensor.

[0011] In one embodiment, the fixing mechanism includes a spring and a trapezoidal block. The spring is fixedly connected to the front end of the storage slot, and the trapezoidal block is fixedly connected to the rear end of the spring. The rear end of the trapezoidal block protrudes out of the storage slot, and the rear end of the trapezoidal block is tilted with the left side lower than the right side.

[0012] In one embodiment, a connecting rod is fixedly installed at the center of the front end of the trapezoidal block. The connecting rod passes through the spring and is installed in the vertical through hole by a sliding connection. The diameter of the connecting rod is adapted to the inner diameter of the vertical through hole.

[0013] In one embodiment, a I-shaped component is fixedly installed at the front end of the connecting rod. The I-shaped component is located at the front end of the trachea body and inside the externally threaded mounting cylinder. Caregivers can quickly install and remove the sensor by pushing and pulling the I-shaped component at the bedside without the need for tools, facilitating routine maintenance and emergency handling.

[0014] In one embodiment, the fixing mechanism and the sensor mounting mechanism form an elastic locking engagement. When the sensor mounting mechanism is pushed into the preset position along the L-shaped mounting groove, the rear end face of the sensor mounting mechanism slides against the inclined surface of the trapezoidal block, forcing the trapezoidal block to retract towards the front end against the spring force. When the sensor mounting mechanism is fully inserted into the L-shaped mounting groove, the trapezoidal block pops out towards the rear end under the reset action of the spring, and the rear end face of the trapezoidal block forms a longitudinal stop engagement with the front end face of the sensor mounting mechanism to restrict the sensor mounting mechanism from sliding forward and dislodging along the L-shaped mounting groove, thereby achieving axial positioning and anti-dislodgement locking of the temperature and humidity sensor on the inner side of the front end of the air tube body.

[0015] In one embodiment, the axis of the spring coincides with the axis of the connecting rod. The front end of the spring is fixedly connected to the inner front wall of the receiving groove, and the rear end of the spring is fixedly connected to the front face of the trapezoidal block. The rear inclined surface of the trapezoidal block is a single inclined surface structure that gradually rises from the lower left to the upper right, and the inclination angle of the inclined surface is 30° to 60°, which is used to generate a smooth guiding force when the sensor mounting mechanism is pushed in. The rear end of the connecting rod is fixedly connected to the middle of the front face of the trapezoidal block, and the front end of the connecting rod passes through the vertical through hole and is fixedly connected to the middle of the rear face of the I-shaped part. An axial gap is left between the front face of the I-shaped part and the front face of the air tube body to ensure that when the I-shaped part is pulled forward, it can drive the trapezoidal block to overcome the elastic force of the spring through the connecting rod, so that the trapezoidal block is completely retracted into the receiving groove, releasing the blocking lock on the sensor mounting mechanism and realizing the detachable replacement of the sensor mounting mechanism.

[0016] In one embodiment, a monitoring module is fixedly installed on the outer wall of the trachea body. The monitoring module is located at the rear end of the airbag and is electrically connected to the temperature and humidity sensor via the wire. The monitoring module includes a housing, a display screen, an alarm indicator light, and a wireless communication unit. The housing is fixedly embedded in the side wall of the trachea body, and the display screen is embedded in the outer surface of the housing for real-time display of the temperature and humidity values ​​detected by the temperature and humidity sensor. The alarm indicator light is used to emit a light alarm signal when the detected value exceeds a preset threshold. The wireless communication unit is used to transmit the detection data to an external monitoring terminal in real time. An annular flexible pad concentrically arranged with the protective net is also fixedly installed on the front end face of the sealing cover. The front end face of the annular flexible pad protrudes from the front end face of the sealing cover to buffer the hard contact between the sealing cover and the patient's oral mucosa or airway opening during intubation.

[0017] In one embodiment, a positioning guide ring is fixedly installed on the outer wall of the front end of the tracheal body. The positioning guide ring is located in front of the two air bladders, and the outer diameter of the positioning guide ring is smaller than the outer diameter of the air bladders after inflation. The outer wall of the positioning guide ring is provided with a plurality of axially extending imaging grooves at equal intervals around the periphery. Each imaging groove is fixedly embedded with a medical imaging strip, which is used to mark the spatial orientation of the front end of the tracheal body under X-ray or CT imaging. The front edge of the positioning guide ring is provided with a guide rounded corner to guide the tracheal body to pass smoothly through the glottis during intubation, reduce scratching damage to the airway wall, and assist in quickly determining the correspondence between the detection orientation of the temperature and humidity sensor and the anatomical position of the airway during surgical operation.

[0018] In one embodiment, a flexible positioning mark ring is fixedly installed on the front end face of the tracheal body. The flexible positioning mark ring is made of silicone, and the front end face of the flexible positioning mark ring is provided with multiple circumferentially distributed arc-shaped protrusions. The arc-shaped protrusions are used to form multiple flexible contacts with the inner wall of the airway during intubation to enhance the placement stability of the front end of the tracheal body. Multiple micro pressure sensing pads are also fixedly embedded inside the flexible positioning mark ring. The positions of the multiple micro pressure sensing pads correspond one-to-one with the positions of the multiple arc-shaped protrusions. The micro pressure sensing pads are electrically connected to the monitoring module through the wires to detect the contact pressure distribution between the front end of the tracheal body and the inner wall of the airway, and transmit the pressure distribution data to the monitoring module. The monitoring module generates an attitude deviation prompt signal of the front end of the tracheal body based on the pressure distribution data, so that the surgeon can adjust the insertion angle of the tracheal body in real time during interventional operations or fiberoptic bronchoscopy, thereby improving the positioning accuracy and safety of the surgical operation.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This device, by placing a temperature and humidity sensor at the front end of the trachea, enables nurses to obtain real-time temperature and humidity data within the patient's airway. This overcomes the drawback of traditional nursing care, which relies solely on ventilator settings for indirect assessment. It avoids problems such as airway mucosal dryness, ciliary dysfunction, and sputum retention caused by temperature and humidity discomfort from the source of care, significantly reducing airway irritation and infection risks.

[0021] Ensuring the safety of nursing procedures: The coordinated design of the fixing mechanism, storage slot, and vertical through hole ensures that the sensor mounting mechanism does not loosen or fall off during frequent nursing procedures such as suctioning, changing body position, and transportation, ensuring the continuity and reliability of monitoring data, avoiding false alarms or data loss due to sensor displacement, and reducing the psychological burden on nursing staff.

[0022] Improving the ease of nursing operations: The external design of the tool-type components allows nursing staff to disassemble and replace the sensor module by hand without special instruments, simplifying the equipment maintenance process and saving nursing time, which is especially suitable for the high-intensity and fast-paced work environment of the ICU.

[0023] Balancing the dual needs of ventilation and monitoring: The arc-shaped design of the mounting plate and rectangular limiting frame fits the airway wall, and the spiral guide wire layout does not occupy the effective space of the airway, ensuring smooth ventilation for patients while achieving accurate monitoring, reflecting the "patient-centered" safety concept in nursing device design.

[0024] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

Detailed Implementation

[0026] To make the technical means, creative features, objectives, and effects of this invention clearer and easier to understand, the invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0027] This invention proposes an endotracheal intubation device with temperature and humidity monitoring function, including an endotracheal body 1, two parallel airbags 2 fixedly installed at the outer front end of the endotracheal body 1, an L-shaped mounting groove 12 provided at the lower part of the inner front end of the endotracheal body 1, a limiting groove 121 provided at the inner end of the L-shaped mounting groove 12 away from the inner wall of the endotracheal body 1, a receiving groove 122 communicating with the L-shaped mounting groove 12 provided at the middle of the inner front end of the L-shaped mounting groove 12, a vertical through hole communicating with the receiving groove 122 provided at the middle of the front end of the receiving groove 122, and the front end of the vertical through hole penetrating the endotracheal body 1, the inner diameter of the receiving groove 122 being larger than the inner diameter of the vertical through hole, and further comprising:

[0028] The sensor mounting mechanism 5 is installed in the L-shaped mounting groove 12. The sensor mounting mechanism 5 is equipped with a temperature and humidity sensor 52. The sensor mounting mechanism 5 is used to fix the temperature and humidity sensor 52 to the inner side of the end of the air tube body 1.

[0029] Fixing mechanism 6 is installed in the storage groove 122 and the vertical through hole. Fixing mechanism 6 is used to position and prevent the sensor mounting mechanism 5 from falling off.

[0030] An external threaded mounting cylinder 11 is fixedly installed at the front end of the trachea body 1. A sealing cap 3 is installed on the outer thread of the external threaded mounting cylinder 11. A protective net 31 is fixedly embedded at the front end of the sealing cap 3.

[0031] A wire 4 is fixedly installed on the inner wall of the trachea body 1, and the wire 4 is distributed in a spiral shape on the inner side of the trachea body 1.

[0032] In this embodiment of the invention, during operation, the sensor mounting mechanism 5 is first embedded into the lower front end of the trachea body 1 through the L-shaped mounting groove 12. The limiting groove 121 guides and initially limits the sensor mounting mechanism 5, ensuring that the temperature and humidity sensor 52 is accurately attached to the inner side of the end of the trachea body 1. Subsequently, the fixing mechanism 6, in cooperation with the receiving groove 122 and the vertical through hole, positions and prevents the sensor mounting mechanism 5 from falling off, ensuring structural stability during monitoring. After the trachea body 1 is inserted into the patient's airway, air is inflated into the airbag 2, causing the airbag 2 to expand and adhere to the inner wall of the airway, thus fixing and sealing the device. The sealing cap 3 on the outside of the external threaded mounting cylinder 11 is tightened. The protective net 31 at its front end can prevent airway secretions or foreign objects from contacting the internal components, providing protection and preventing the temperature and humidity sensor 52 from falling into the patient's body. The temperature and humidity sensor 52 is powered by an external medical-grade power supply module, which transmits power through the spirally distributed wires 4 on the inner wall of the trachea body 1. The spiral design ensures power supply stability without occupying the effective space of the airway or affecting airflow. The temperature and humidity sensor 52 collects temperature and humidity data in the trachea in real time and transmits the data to an external monitoring terminal through the wires 4. The terminal can preset temperature and humidity safety thresholds. When the detected data exceeds the threshold, the terminal automatically issues an alarm signal, and medical staff can intervene and make timely adjustments.

[0033] In one embodiment of the present invention, a sensor mounting mechanism 5 is set inside the trachea body 1, which, together with the L-shaped mounting groove 12 and the limiting slide groove 121, enables the stable installation of the temperature and humidity sensor 52. This fills the gap in traditional devices that lack temperature and humidity monitoring components. The temperature and humidity sensor 52 can capture the environmental parameters inside the trachea in real time and transmit them to an external terminal through the wire 4. This effectively avoids problems such as dry airway mucosa and abnormal secretions caused by unsuitable gas temperature and humidity, and significantly reduces the risk of airway irritation and infection for patients. The cooperation between the fixing mechanism 6, the storage slot 122, and the vertical through hole ensures that the sensor mounting mechanism 5 does not fall off or shift during the use of the device, thus ensuring the continuity and accuracy of the monitoring data. The threaded connection design between the external threaded mounting cylinder 11 and the sealing cover 3 facilitates disassembly and maintenance and enhances the sealing performance of the front end of the device. The protective net 31 can effectively block the intrusion of foreign objects and extend the service life of internal components. The setting of the airbag 2 not only achieves stable fixation of the device in the airway but also reduces gas leakage. Combined with the reasonable layout of the spiral wire 4, it ensures the safe and stable operation of the electrical structure without affecting the normal ventilation function of the airway, thereby improving the clinical applicability and safety of the device.

[0034] In one embodiment, such as Figures 1-5 As shown, this is a preferred embodiment of the present invention:

[0035] The sensor mounting mechanism 5 includes a mounting plate 51, which is inserted into an L-shaped mounting groove 12. A rectangular limiting frame 511 is fixedly installed on the lower outer side of the mounting plate 51. The rectangular limiting frame 511 is inserted into a limiting slide groove 121 via a sliding connection. The shape of the mounting plate 51 matches the shape of the L-shaped mounting groove 12, and the shape of the rectangular limiting frame 511 matches the shape of the limiting slide groove 121. Both the mounting plate 51 and the rectangular limiting frame 511 are arc-shaped, and the curvature of the mounting plate 51 and the rectangular limiting frame 511 matches the arc shape of the inner wall of the air tube body 1. The temperature and humidity sensor 52 is fixedly installed in the middle of the upper end of the mounting plate 51. A detection head 521 is fixedly installed in the middle of the front end of the temperature and humidity sensor 52.

[0036] The fixing mechanism 6 includes a spring 61 and a trapezoidal locking block 62. The spring 61 is fixedly connected to the front end of the storage groove 122. The trapezoidal locking block 62 is fixedly connected to the rear end of the spring 61, and the rear end of the trapezoidal locking block 62 protrudes out of the storage groove 122. The rear end of the trapezoidal locking block 62 is inclined with the left side lower and the right side higher. A connecting rod 63 is fixedly installed in the middle of the front end of the trapezoidal locking block 62. The connecting rod 63 passes through the spring 61 and is installed in the vertical through hole by sliding connection. The diameter of the connecting rod 63 is matched with the inner diameter of the vertical through hole. A I-shaped part 64 is fixedly installed at the front end of the connecting rod 63. The I-shaped part 64 is located at the front end of the air pipe body 1 and is located inside the external threaded mounting cylinder 11.

[0037] In this embodiment of the invention, the mounting plate 51 is first inserted along the L-shaped mounting groove 12. The rectangular limiting frame 511 slides in conjunction with the limiting slide groove 121. Since both the mounting plate 51 and the rectangular limiting frame 511 are arc-shaped and adapted to the curvature of the inner wall of the airway body 1, it can ensure that the device fits the inner wall of the airway after installation and does not affect the airflow. During the insertion process, the front end of the mounting plate 51 presses against the inclined surface of the trapezoidal locking block 62, causing the trapezoidal locking block 62 to compress the spring 61 and retract into the storage groove 122. When the mounting plate 51 is fully in place, the spring 61 resets and pushes the trapezoidal locking block 62 out of the storage groove 122, locking the mounting plate 51 to achieve positioning. If disassembly is required, the I-shaped part 64 can be pulled, and the trapezoidal locking block 62 can be retracted into the storage groove 122 through the connecting rod 63. After the device is implanted into the airway, the airbag 2 is inflated and fixed, and the sealing cap 3 is tightened to place the protective net 31 in the front protective position of the airway. The temperature and humidity sensor 52 is connected to an external medical power supply module via a wire 4. The spiral wire 4 ensures stable power transmission without interfering with airway ventilation. The detection head 521 of the temperature and humidity sensor 52 directly contacts the gas in the patient's trachea, collects temperature and humidity data in real time, and transmits it to an external monitoring device via the wire 4. The device can be set with a dynamic threshold range and automatically alarms when the data is abnormal. Medical staff can adjust ventilation parameters based on the monitoring results. At the same time, the fixed layout of the wire 4 avoids direct contact between the electrical components and the airway mucosa, improving safety during use.

[0038] In one embodiment of the present invention, the sensor mounting mechanism 5 adopts a combination structure of mounting plate 51 and rectangular limiting frame 511, with L-shaped mounting groove 12 and limiting slide groove 121 for guiding and limiting, which not only ensures the installation stability of temperature and humidity sensor 52, but also its arc design fits the inner wall of trachea body 1 better, reducing irritation to airway mucosa. The setting of detection head 521 improves the accuracy of temperature and humidity data acquisition. The fixing mechanism 6 achieves quick disassembly and stable positioning of sensor mounting mechanism 5 through the synergistic action of spring 61, trapezoidal block 62, connecting rod 63 and I-shaped part 64. The inclined design of trapezoidal block 62 facilitates automatic avoidance during installation, and the external design of I-shaped part 64 makes disassembly convenient without complicated tools, improving clinical use efficiency; the matching design of connecting rod 63 and vertical through hole ensures the movement stability of trapezoidal block 62 and avoids gas leakage. The spiral distribution of the lead wire 4 ensures the power supply stability and data transmission reliability of the temperature and humidity sensor 52 without occupying the effective ventilation space of the airway. Combined with the threshold alarm function of the external monitoring terminal, it can promptly avoid airway risks caused by abnormal temperature and humidity. Furthermore, the cooperation between the external threaded mounting sleeve 11 and the sealing cap 3, the protective function of the protective net 31, and the fixing and sealing effect of the airbag 2 collectively improve the device's sealing performance, safety, and service life, effectively reducing the probability of airway irritation and infection in patients. At the same time, it simplifies the operating procedures for medical staff and improves the quality of clinical nursing care.

[0039] The working principle of this invention is as follows: In use, the sensor mounting mechanism 5, equipped with a temperature and humidity sensor 52, is first inserted into the L-shaped mounting groove 12 at the lower front end of the air tube body 1. The mounting plate 51 and the rectangular limiting frame 511 slide along the limiting groove 121. During insertion, the mounting plate 51 presses against the inclined surface of the trapezoidal block 62, causing the trapezoidal block 62 to compress the spring 61 and retract into the receiving groove 122. After the mounting plate 51 is fully in place, the spring 61 resets and pushes the trapezoidal block 62 out of the receiving groove 122 to achieve positioning. During disassembly, the I-shaped part 64 can be pulled to retract the trapezoidal block 62 via the connecting rod 63. The fixing mechanism 6, in cooperation with the receiving groove 122 and the vertical through hole, completes the positioning of the sensor mounting mechanism 5. After positioning to prevent dislodgement, the trachea body 1 is inserted into the patient's airway, and the cuff 2 is inflated to expand and fit against the inner wall of the airway for fixation and sealing. The sealing cap 3 on the outside of the external threaded mounting cylinder 11 is tightened, and the protective net 31 prevents foreign objects from contacting the internal components. The temperature and humidity sensor 52 is powered by an external medical-grade power supply module through the spirally distributed wires 4 on the inner wall of the trachea body 1. The spiral wires 4 ensure stable power supply without affecting airflow. The temperature and humidity sensor 52 collects temperature and humidity data in the trachea in real time and transmits it to the external monitoring terminal via the wires 4. The terminal has a preset safety threshold, and an alarm is automatically triggered when the data exceeds the threshold. Medical staff can make timely adjustments. The overall structure ensures continuous monitoring without occupying effective airway space or affecting ventilation.

[0040] The fixing mechanism 6 and the sensor mounting mechanism 5 form an elastic locking relationship. When the sensor mounting mechanism 5 is pushed into the preset position along the L-shaped mounting groove 12, the rear end face of the sensor mounting mechanism 5 slides against the inclined surface of the trapezoidal block 62, forcing the trapezoidal block 62 to retract towards the front end against the elastic force of the spring 61. When the sensor mounting mechanism 5 is fully inserted into the L-shaped mounting groove 12, the trapezoidal block 62 pops out towards the rear end under the reset action of the spring 61, and the rear end face of the trapezoidal block 62 forms a longitudinal stop with the front end face of the sensor mounting mechanism 5 to restrict the sensor mounting mechanism 5 from sliding forward and falling out along the L-shaped mounting groove 12. This achieves axial positioning and anti-fall-out locking of the temperature and humidity sensor 52 on the inner side of the front end of the trachea body 1. This design, through the "push-in self-locking, stop-fall-out" mechanism, can achieve stable installation of the sensor without external tools, effectively preventing the sensor from accidentally falling out due to suctioning, patient coughing, or transport bumps.

[0041] In this invention, the axis of spring 61 coincides with the axis of connecting rod 63. The front end of spring 61 is fixedly connected to the inner front wall of the receiving groove 122, and the rear end of spring 61 is fixedly connected to the front face of trapezoidal block 62. The rear inclined surface of trapezoidal block 62 is a single inclined surface structure that gradually rises from the lower left to the upper right with an inclination angle of 30° to 60°, which is used to generate a smooth guiding force when the sensor mounting mechanism 5 is pushed in. The rear end of connecting rod 63 is fixedly connected to the middle of the front face of trapezoidal block 62, and the front end of connecting rod 63 passes through the vertical through hole and is connected to the rear end of I-shaped part 64. The middle part is fixedly connected; there is an axial gap between the front end face of the I-shaped part 64 and the front end face of the air tube body 1, so as to ensure that when the I-shaped part 64 is pulled forward, it can drive the trapezoidal block 62 to overcome the elastic force of the spring 61 through the connecting rod 63, so that the trapezoidal block 62 can be completely retracted into the storage groove 122, releasing the blocking lock on the sensor mounting mechanism 5, realizing the detachable replacement of the sensor mounting mechanism 5. This design constructs an elastic locking system with four advantages: "low resistance push-in, high reliability self-locking, anti-accidental contact safety, and convenient disassembly".

[0042] A monitoring module is also fixedly installed on the outer wall of the trachea body 1. The monitoring module is located at the rear end of the airbag 2 and is electrically connected to the temperature and humidity sensor 52 through the wire 4. The monitoring module includes a housing, a display screen, an alarm indicator light, and a wireless communication unit. The housing is fixedly embedded in the side wall of the trachea body 1. The display screen is used to display the temperature and humidity values ​​detected by the temperature and humidity sensor 52 in real time. The alarm indicator light is used to emit a light alarm signal when the detected value exceeds a preset threshold. The wireless communication unit is used to transmit the detection data to an external monitoring terminal in real time. At the same time, an annular flexible pad is fixedly installed on the front end of the sealing cover 3, which is concentric with the protective net 31. The front end of the annular flexible pad protrudes from the front end of the sealing cover 3 to buffer the hard contact between the sealing cover 3 and the patient's oral mucosa or airway opening during intubation. This design realizes bedside visualization and remote continuous monitoring of airway temperature and humidity parameters, and reduces the risk of iatrogenic injury during intubation through the flexible buffer structure.

[0043] A positioning guide ring is also fixedly installed on the outer wall of the front end of the tracheal body 1 of the present invention. The positioning guide ring is located in front of the two air bags 2 and its outer diameter is smaller than the outer diameter of the air bags 2 after inflation. Multiple axially extending imaging grooves are evenly spaced on the outer wall of the positioning guide ring. A medical imaging strip is fixedly embedded in each imaging groove to mark the spatial orientation of the front end of the tracheal body 1 under X-ray or CT imaging. The front edge of the positioning guide ring is provided with a guide rounded corner to guide the tracheal body 1 to pass smoothly through the glottis during intubation, reduce the scratching damage to the airway wall, and assist in quickly determining the correspondence between the detection orientation of the temperature and humidity sensor 52 and the anatomical position of the airway during surgical operation. This design organically combines the imaging positioning function with the temperature and humidity monitoring function, providing a precise spatial positioning reference for interventional surgery.

[0044] A flexible positioning mark ring is also fixedly installed on the front end face of the tracheal body 1 of the present invention. The flexible positioning mark ring is made of silicone and has multiple circumferentially distributed arc-shaped protrusions on its front end face. It is used to form multiple flexible contacts with the inner wall of the airway during the intubation process to enhance the stability of the intubation at the front end of the tracheal body 1. Multiple micro pressure sensing pads are also fixedly embedded inside the flexible positioning mark ring. The positions of the multiple micro pressure sensing pads correspond one-to-one with the positions of the multiple arc-shaped protrusions. The micro pressure sensing pads are electrically connected to the monitoring module through wires 4. They are used to detect the contact pressure distribution between the front end of the tracheal body 1 and the inner wall of the airway and transmit the pressure distribution data to the monitoring module. The monitoring module generates a posture deviation prompt signal of the front end of the tracheal body 1 based on the pressure distribution data, so that the surgeon can adjust the insertion angle of the tracheal body 1 in real time during interventional operation or fiberoptic bronchoscopy. This design realizes the functional leap of tracheal intubation from passive fixation to active sensing and from single monitoring to multi-dimensional assistance through the intelligent positioning system of "flexible contact + pressure sensing + posture feedback". It significantly improves the positioning accuracy and safety of surgical operation.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.

The medical imaging strip is used to mark the spatial orientation of the front end of the tracheal body (1) under X-ray or CT imaging. The front edge of the positioning guide ring is provided with a guide rounded corner to guide the tracheal body (1) to pass smoothly through the glottis during intubation, reduce the scratching damage to the airway wall, and assist in quickly determining the correspondence between the detection orientation of the temperature and humidity sensor (52) and the anatomical position of the airway during surgical operation.

10.

The flexible positioning mark ring is also fixedly embedded with multiple micro pressure sensing pads. The positions of the multiple micro pressure sensing pads correspond one-to-one with the positions of the multiple arc-shaped protrusions. The micro pressure sensing pads are electrically connected to the monitoring module through the wire (4) to detect the contact pressure distribution between the front end of the tracheal body (1) and the inner wall of the airway, and transmit the pressure distribution data to the monitoring module. The monitoring module generates an attitude deviation prompt signal of the front end of the tracheal body (1) based on the pressure distribution data, so that the surgeon can adjust the insertion angle of the tracheal body (1) in real time during interventional operation or bronchoscopy, thereby improving the positioning accuracy and safety of the surgical operation.
