Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, specifically to a tracheal tube device that can change color with temperature. Background Technology

[0002] An endotracheal tube is a medical device used for airway management, typically for endotracheal intubation, to ensure airway patency, assist patients in breathing, or manage anesthesia.

[0003] After general anesthesia, the thermoregulatory system is suppressed to varying degrees, and patients lose their physiological temperature regulation. Perioperative expert consensus indicates that a core body temperature below 35.5°C during the perioperative period may be associated with adverse outcomes such as cardiovascular events and surgical site infection. Therefore, perioperative temperature monitoring is considered one of the basic vital signs. Currently, clinical practice commonly uses temperature monitors to monitor the temperature of different sites depending on the placement of the temperature probe. Patients under general anesthesia often require endotracheal intubation for mechanical ventilation, but existing anesthetic ventilation procedures have the following drawbacks:

[0004] (1) When the endotracheal tube is used for ventilation, its cuff is located through the nasopharynx or even below the glottis, close to the esophagus. However, the existing endotracheal tube is only a single ventilation device and cannot sense or display temperature, so its functionality is poor.

[0005] (2) At present, in clinical practice, body temperature monitoring and mechanical ventilation through endotracheal tubes under general anesthesia are two different components and modules. The two are not integrated, which increases medical costs. At the same time, some body temperature probes often cause nasal bleeding when placed in the nasopharynx. In addition, most hospitals reuse body temperature probes, which increases the chance of iatrogenic infection.

[0006] In view of the above, a tracheal tube device that can change color with temperature is proposed to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this invention is to provide a tracheal tube device that changes color with temperature, in order to solve the existing problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a temperature-sensitive endotracheal tube device, comprising a tube body, a cuff fixedly fitted on one side of the tube body, an air injection tube fixedly connected to the middle of the cuff, a one-way ventilation valve fixedly connected to one end of the air injection tube, a polymer thermally conductive sensing layer coated on both the surface of the tube body and the surface of the cuff, a temperature monitoring probe fixedly connected to the inner wall of the cuff, a retaining ring engaged on one side of the one-way ventilation valve, a temperature display fixedly connected to the surface of the retaining ring, a wire inserted into the inside of the air injection tube, one end of the wire fixedly connected to the temperature monitoring probe, and the other end of the wire fixedly connected to the temperature display.

[0009] When using the temperature-sensitive endotracheal tube device of this technical solution, the device can monitor body temperature while providing ventilation. The two functions are integrated, reducing medical trauma and costs, and visually displaying changes in body temperature, thus providing assurance for perioperative anesthesia management.

[0010] In a preferred embodiment of this invention, a steel wire coil is inserted into the inner wall of the catheter body. The steel wire coil serves as a support, ensuring the strength and flexibility of the catheter.

[0011] As a preferred embodiment of this invention, one end of the catheter body is provided with a beveled opening. The beveled opening facilitates the insertion of the catheter.

[0012] In a preferred embodiment of this invention, a connector is fixedly connected to the end of the catheter body away from the inclined opening. The connector is used to connect the catheter body to external equipment.

[0013] As a preferred embodiment of this utility model, the catheter body is made of transparent polymer material, and the cuff is a high-pressure, low-volume sleeve type.

[0014] As a preferred embodiment of this invention, the surface of the catheter body is printed with graduation lines. These graduation lines facilitate the doctor's understanding of the insertion depth of the catheter body.

[0015] In a preferred embodiment of this invention, a positioning ring is fixedly connected to the side of the conduit body near the connector. The air injection tube can be secured to the positioning ring to prevent it from easily shaking.

[0016] In a preferred embodiment of this invention, lifting blocks are fixedly connected to both sides of the one-way vent valve. These lifting blocks facilitate the movement and handling of the one-way vent valve.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This device combines endotracheal tube ventilation under general anesthesia with body temperature monitoring, avoiding the drawbacks of only being able to perform ventilation without monitoring body temperature. Furthermore, the endotracheal tube can display different colors within a certain body temperature range, while also allowing for intuitive body temperature monitoring. Visually, it can provide anesthesiologists with direct warnings, and it can also continuously monitor body temperature changes and replay the temperature data for analysis and research.

[0019] 2. This device makes mechanical ventilation via endotracheal tube and temperature monitoring during general anesthesia more convenient and accurate, and enables anesthesiologists to manage anesthesia more precisely during the perioperative period. The combination of the two can reduce medical costs and reduce the risk of additional trauma and opportunistic infections for patients, without affecting the anesthesiologist's ability to perform mechanical airway ventilation.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4This utility model provides a temperature-sensitive endotracheal tube device, including a tube body 1, a cuff 2 fixedly fitted on one side of the surface of the tube body 1, which seals the gap between the endotracheal tube and the tube by inflation to ensure no air leakage. An inflation tube 3 is fixedly connected to the middle of the cuff 2 for inflating the cuff 2. One end of the inflation tube 3 is fixedly connected to a one-way ventilation valve 4. Both the surface of the tube body 1 and the surface of the cuff 2 are coated with a polymer thermally conductive sensing layer 6, which changes color according to temperature. A temperature monitoring probe 10 is fixedly connected to the inner wall of the cuff 2. A retaining ring 9 is engaged on one side of the surface of the one-way ventilation valve 4. A temperature display 8 is fixedly connected to the surface of the retaining ring 9 to display the temperature value. A wire 11 is inserted and connected inside the inflation tube 3. One end of the wire 11 is fixedly connected to the temperature monitoring probe 10, and the other end of the wire 11 is fixedly connected to the temperature display 8 for electrical connection.

[0027] In use, the outer layer of the catheter body 1 is coated with a thermally conductive sensing material, which can sense different temperature changes and display different colors. The outer layer of the cuff 2 is also coated with a thermally conductive sensing material, which can sense different temperature changes and display different colors and temperature values. The inflator tube 3 is used to inflate the cuff 2 with air, usually about 5 ml of gas, so that the pressure in the cuff 2 is maintained between 25-30 cmH2O. The lead wire 11 can be lined inside the inflator tube 3 without blocking its flow. The temperature display 8 is an electronic device that can display the temperature. It is mounted on the one-way ventilation valve 4 to display the temperature value. The temperature monitoring probe 10 is used to detect the temperature of the trachea and esophagus.

[0028] A steel wire coil 5 is inserted into the inner wall of the catheter body 1 to provide support. One end of the catheter body 1 has a beveled opening 7 for easy operation. The end of the catheter body 1 away from the beveled opening 7 is fixedly connected to a connector 12 for connection. The catheter body 1 is made of transparent polymer material, and the sleeve 2 adopts a high-pressure, low-volume sleeve type.

[0029] In use, the catheter body 1 is clinically made of polymer material and lined with a steel wire coil 5 to improve strength and flexibility. The beveled opening 7 at one end of the catheter body 1 facilitates its insertion into the trachea without altering the normal structure of the tracheal tube. The connector 12 at the other end is used to connect to the anesthesia gas supply equipment.

[0030] The surface of the catheter body 1 is marked with scale lines 13 for marking depth. A positioning ring 14 is fixedly connected to the side of the catheter body 1 near the connector 12 for fixing the air injection tube 3. Lifting blocks 15 are fixedly connected to both sides of the one-way ventilation valve 4 for easy operation.

[0031] When in use, the scale line 13 on the catheter body 1 allows for accurate control of the insertion depth of the catheter body 1 during insertion. The top of the air injection tube 3 can be locked on the positioning ring 14, thus preventing bending or shaking. The lifting block 15 facilitates the movement of the one-way ventilation valve 4.

[0032] In practical use, this utility model provides a temperature-sensitive endotracheal tube device. The tube body 1 is clinically made of polymer material, with an embedded steel wire coil 5 to improve strength and flexibility. This design incorporates a thermally conductive sensing material on the outer layer, allowing it to detect temperature changes and display different colors. Its distal end has a beveled opening 7, without altering the normal structure of the endotracheal tube. The high-pressure, low-volume sleeve-shaped ventilation cuff 2 is also coated with a thermally conductive sensing material, allowing it to detect temperature changes and display different colors and temperature values. The inflator tube 3 is used to inflate the cuff 2, typically injecting approximately 5 ml of air. Gas is used to maintain the pressure in cuff 2 at approximately 25-30 cmH2O. Lead wire 11 can be lined inside the inflator tube 3 without obstructing its flow. Temperature display 8 is an electronic device that displays temperature, mounted on the one-way ventilation valve 4 to show the temperature value. Temperature monitoring probe 10 is used to detect tracheal and esophageal temperatures. The high-polymer thermally conductive sensing material displays different colors within a certain temperature range according to changes in the patient's body temperature, providing a visual effect for the anesthesiologist. For example, yellow below 35℃, blue between 35℃ and 37℃, and red above 37℃. Simultaneously, this high-polymer... The materials used should be non-toxic and non-corrosive, and should not expand or deform when exposed to heat or water, posing no adverse effects on life and health. The temperature display should be waterproof and leak-proof, with built-in electronic equipment. Data can be copied and stored. General anesthesia and mechanical ventilation can be performed via an endotracheal tube to complete clinical anesthesia. Temperature monitoring allows for temperature management, preventing intraoperative hypothermia. The combination of these two features reduces medical costs and mitigates the drawbacks of nasal mucosal damage and bleeding caused by nasopharyngeal temperature monitoring. It also does not occupy space for airway management and provides anesthesiologists with intuitive visualization of anesthesia management. Temperature management is an integral part of anesthesia quality control. This device is a key feature, making perioperative airway management and temperature monitoring more convenient. It facilitates mechanical ventilation via endotracheal tubes under general anesthesia and improves the accuracy of temperature monitoring, enabling anesthesiologists to manage anesthesia more precisely during the perioperative period. The combination of these two features can reduce the risk of additional trauma and opportunistic infections for patients, without affecting the anesthesiologist's ability to perform mechanical airway ventilation. The different colors displayed by the endotracheal tube within a certain temperature range provide an immediate visual alert for the anesthesiologist, facilitating the timely detection of adverse events such as hypothermia. The temperature data can be tracked, played back, and copied for clinical research, and its widespread adoption can benefit a large number of patients.
