Description

Technical Field

[0001] The invention relates to the technical field of endotracheal cannulas for medical care, and in particular to a position change warning mechanism for endotracheal cannulas for ICU care. Background Art

[0002] ICU usually refers to the Intensive Care Unit, which is a specialized medical facility that provides high-level, continuous monitoring and treatment for critically ill patients. ICU mainly treats patients with unstable vital signs, severely damaged organ function or patients who need close observation, such as patients with severe trauma, cardiopulmonary failure, multiple organ dysfunction syndrome (MODS) or patients who need special care after surgery. It is equipped with advanced monitoring equipment (such as ECG monitors, ventilators, blood gas analyzers, etc.) and a professional medical team, including critical care doctors and professional nurses.

[0003] In the ICU care environment, patients often need continuous life support due to various critical conditions, including long-term mechanical assisted ventilation, and endotracheal intubation is one of the most common and critical means of achieving such support. Endotracheal intubation maintains the patient's respiratory function by inserting a special tube into the patient's airway to ensure the patency of the airway and facilitate the connection of mechanical ventilation equipment.

[0004] When using the existing ICU nursing endotracheal tube, medical staff need to use instruments such as laryngoscopes to determine the patient's tracheal position, insert the tube body into the patient's trachea through the mouth, and finally, connect the tube body away from the medical bracket to the existing ventilator, set appropriate parameters, ensure airway patency, and thus ensure the normal use of the tube. When the patient has high-frequency breathing, coughing, throat and other reflex activities, especially in conscious or uncooperative patients, they will actively cough, swallow or move their heads, resulting in the displacement of the tube body position. The early warning agency can promptly detect abnormalities in the tube position and monitor changes in the endotracheal tube position, such as tube dislocation or displacement, to avoid serious consequences such as suffocation in patients. In addition, by automatically monitoring the patient's endotracheal tube position, the nurse's workload can be reduced and nursing efficiency can be improved.

[0005] Although traditional early warning agencies can detect situations such as tube displacement and dislocation when monitoring abnormal endotracheal tube position, their alarm methods usually rely on simple sound and light prompts or data updates, which lack sufficient strength and pertinence, resulting in an inability to quickly attract the attention of nursing staff. In the ICU environment, nursing staff often manage multiple patients at the same time and need to respond to various emergencies. Sound alarms are easily masked by noisy environments or interfered with by alarms from other devices, thereby delaying the response time of medical staff. In addition, traditional early warning agencies usually only have a single alarm function, which makes it impossible to quickly close the trachea when the tube is displaced or dislocated. This limitation makes it easy for patients to face serious consequences such as suffocation due to the inability of nursing staff to respond in time when the tube position is dangerously shifted or dislocated. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention provides an endotracheal tube position change warning mechanism for ICU nursing, which solves the problem that the prior art usually relies on simple sound and light prompts or data updates, lacks sufficient strength and specificity, and cannot quickly close the trachea when the intubation is abnormal.

When the threaded rod 12 is rotated, it can be convenient to disengage from the threaded hole 11 and the movable column 4. After the threaded rod 12 and the threaded hole 11 are disengaged, the height of the movable column 4 can be conveniently adjusted. When the adjustment is completed, the threaded rod 12 and the threaded hole 11 can be connected and fixed, so as to facilitate the support and fixation of the adjusted movable column 4, while reducing the labor intensity of medical staff.

[0049] Please see attached Figure 2 , Attachment Figure 4 and attached Figure 5 The bottom of the adjusting column 10 is fixedly connected to a fixing frame 3, the bottom of the fixing frame 3 is fixedly connected to a supporting column 2, a clamping assembly is provided in the middle of the supporting column 2, which is used to clamp and fix the supporting column 2, and the clamping assembly includes a compression spring 15, the compression spring 15 is fixedly connected to the middle of the supporting column 2, a slide groove 16 and a clamping groove 17 are provided in the middle of the supporting column 2, a slider 14 is slidably connected to the middle of the supporting column 2, the slider 14 and the clamping groove 17 are clamped, and the bottom of the slider 14 is fixedly connected to the supporting plate 1.

[0051] Please see attached Fig. 9 and attached Fig.10The monitoring component includes a tension sensor 18, which is fixedly connected to one side of the display 5. An image sensor 33 is fixedly connected to one side of the fixing plate 28 close to the support tube 21. The image sensor 33 and the tension sensor 18 are electrically connected to a monitoring system.

[0052] Please see attached Fig.10 , the monitoring system includes:

[0053] A control module, which is used to receive sensor signals, process data and issue control instructions;

[0054] A sensing module, which is used to monitor the deviation of the cannula 6 and transmit the deviation signal to the control module;

[0055] The execution module is used to control the mechanical structure to adjust and seal the cannula 6, thereby completing the compensation control of the deviation.

[0056] The core of the monitoring system consists of three main modules: control module, sensor module and execution module. Each module cooperates with each other to form a complete closed-loop control system. The control module is the center of the system, responsible for receiving the signal transmitted by the sensor module, performing data processing and logic analysis, and issuing precise control instructions according to the operating status of the system. Its role is not only simple signal forwarding, but also includes in-depth analysis and processing of signals to ensure the accuracy and timeliness of control instructions. As the perception unit of the system, the sensor module is mainly responsible for real-time monitoring of the displacement of the cannula 6, detecting physical displacement through the tension sensor 18, capturing visual displacement through the image sensor 33, forming a comprehensive data feedback, and transmitting these displacement signals to the control module to provide dynamic perception information for the system. The execution module is the operating unit of the system, which drives the relevant mechanical structure to adjust the action according to the instructions generated by the control module. It performs precise adjustment and sealing operations on the cannula 6. The three modules are interconnected and work together in real time to form an efficient closed-loop system that can quickly perceive the displacement, accurately analyze the data and perform corrective operations, realizing fully automatic monitoring and adjustment control of the displacement of the cannula 6.

[0057] Please see attached Fig.10 , the control module includes:

[0058] A signal acquisition unit, which is used to receive signals from sensors such as the tension sensor 18 and the image sensor 33, and transmit analog signals or digital signals to subsequent units;

[0059] A signal processing unit, which is used to filter, amplify, convert and correct the collected signals and extract useful information "such as offset and direction";

[0060] A logic control unit, which is used to generate control instructions based on the processed signals according to a preset algorithm or logic rule;

[0061] The communication unit is used to realize two-way communication of signals between the control module and other modules such as the sensor module and the execution module to ensure the accurate transmission of data and instructions.

[0062] The control module is composed of multiple key units, each of which has a clear division of labor and cooperates with each other to ensure the efficient operation of the entire system. First, the signal acquisition unit is a bridge between the control module and the sensor module. Its main function is to receive signals from a variety of sensors, such as the physical offset signal provided by the tension sensor 18 and the visual offset signal captured by the image sensor 33. Whether the signal is in analog or digital form, the signal acquisition unit can effectively receive and pass it to the subsequent processing unit. Then, the signal processing unit is responsible for deep processing of the collected signal. It removes interference noise in the signal through filtering technology and improves signal strength through amplification technology to ensure data quality; at the same time, the unit also converts and corrects the signal format to meet system requirements and extracts key useful information, such as the offset direction and specific offset of the cannula 6. The processed signal is transmitted to the logic control unit, which is the core decision-making layer of the control module. The logic control unit analyzes and calculates the signal data based on the preset control algorithm or logic rules to generate clear control instructions. These instructions will directly determine the specific actions of the execution module, including adjusting the mechanical structure. Finally, the communication unit is responsible for establishing an efficient two-way communication channel between the control module and other modules. This unit ensures that the signals transmitted by the sensor module can be received by the control module in a timely and accurate manner, and also ensures that the instructions generated by the control module can be quickly transmitted to the execution module, thereby achieving real-time response of the system. Through the division of labor and cooperation of these units, the control module can complete the entire process of signal reception, data processing, decision generation and information transmission, ensuring the intelligent and efficient operation of the monitoring system.

[0063] Please see attached Figure 1 and attached Figure 2 A top block 8 is installed on the top of the connecting column 7, and a plurality of connecting rings 9 are fixedly connected to the outside of the top block 8. The plurality of connecting rings 9 are used to connect and support other objects such as hanging bottles.

[0064] The connecting column 7 can conveniently support and fix the top block 8, and the top block 8 can conveniently support and fix multiple connecting rings 9, thereby improving the overall applicability of the equipment and reducing the labor intensity of medical staff.

[0065] Working principle: When the cannula 6 is deviated and sealed, the tension sensor 18 and the image sensor 33 will monitor and transmit signals. When the tension sensor 18 and the image sensor 33 detect that the cannula 6 is deviated, the monitored signals will be transmitted to the control module. The control module will control the motor 20 to work. When the motor 20 is working, it will drive the rotating rod 27 to rotate. When the rotating rod 27 rotates, it will drive the pulley 26 to rotate at the same time. When the pulley 26 rotates, it will drive the turntable 22 to rotate through the synchronous belt 25. When the turntable 22 rotates, it will drive the T-bar 23 to move through the groove in the middle. When the T-bar 23 moves, it will drive the clamping block 24 to move at the same time. When the clamping block 24 moves, it will squeeze and seal the cannula 6.

[0066] When the height of the movable column 4 is adjusted, the knob 13 is manually driven to rotate. When the knob 13 is rotated, the threaded rod 12 is driven to rotate at the same time, so that the threaded rod 12 is disengaged from the threaded hole 11 and the movable column 4. When the threaded rod 12 is disengaged from the threaded hole 11 and the movable column 4, the movable column 4 can be driven to move upward. After the movable column 4 is adjusted to the required position, the movable column 4 can be limited and fixed by the threaded rod 12 and the threaded hole 11.

[0067] When the support column 2 and the support plate 1 need to be connected, fixed or separated, the support column 2 is manually driven to move downward. When the support column 2 moves downward, the compression spring 15 is squeezed. When the compression spring 15 is squeezed and the support column 2 moves downward, the slider 14 slides from the slot 17 to the middle of the slide groove 16. When the slider 14 slides into the middle of the slide groove 16, the support column 2 is rotated, so that the support column 2 and the support plate 1 can be separated or connected and fixed.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
