Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a percutaneous tracheal intubation bundled rescue device. Background Technology

[0002] Currently, oral endotracheal intubation is the standard technique for pediatric airway management. For children with difficult airways, endoscopic-guided oral endotracheal intubation is primarily used, but oral endotracheal intubation has certain limitations. In children with difficult endotracheal intubation, factors such as congenital developmental abnormalities, tumor obstruction, or subglottic stenosis may prevent various forms of endotracheal intubation from passing through the glottis, ultimately making it impossible to establish translaryngotracheal airway ventilation.

[0003] For children, especially infants, if endotracheal intubation fails and emergency resuscitation is required, cricothyroid membrane puncture is difficult to perform in children due to the narrowness of the cricothyroid membrane. Tracheotomy is also challenging in pediatric patients because the young age of the patient makes it difficult to palpate the normal laryngeal and cricoid cartilages. Emergency tracheotomy is further complicated by factors such as time constraints, differences in operator experience, and insufficient teamwork. Furthermore, children have a short tolerance for hypoxia; if ventilation is not effectively improved within minutes, irreversible brain damage or even brain death can occur, posing a serious threat to the child's life.

[0004] Therefore, when performing emergency resuscitation on pediatric patients with difficult airways, it is impossible to perform endotracheal intubation, cricothyroid membrane puncture, or tracheotomy. Airway ventilation cannot be achieved in a short time, resulting in a high incidence of brain injury and seriously affecting the life safety of the children. Utility Model Content

[0005] The purpose of this invention is to provide a percutaneous endotracheal intubation bundled rescue device to alleviate the problem that existing technologies cannot achieve airway ventilation in a short time when performing emergency rescue of pediatric patients with difficult airways, as they are unable to perform oral endotracheal intubation, cricothyroid membrane puncture, or tracheotomy.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0007] A percutaneous endotracheal intubation bundled rescue device includes:

[0008] A tracheostomy cannula assembly, comprising a needle core and an outer cannula, wherein the outer cannula is disposed outside the needle core, and the needle core is used for percutaneous puncture and guiding the outer cannula into the trachea;

[0009] A connecting pipe, which enables gas communication with the outer casing;

[0010] A bidirectional gas delivery mechanism is connected to the junction connection pipe and is used for bidirectional gas exchange with the junction connection pipe.

[0011] Furthermore, it also includes an intermediate connector, with a first interface and a second interface respectively provided at both ends of the intermediate connector. The needle core and the outer tube are both connected to the first interface. The intermediate connector has a cavity structure. The second interface is used to allow the needle core to leave the intermediate connector and connect to the confluence connecting tube.

[0012] Furthermore, the intermediate connector is provided with fixing wings on both sides, which are used to fit and fix the needle core to the human neck during puncture.

[0013] Furthermore, the tracheal puncture cannula assembly is provided with a detection element, which is used to detect the puncture site of the needle core.

[0014] Furthermore, the detection element includes a probe disposed on the needle core, and the probe is signal-connected to an external display device.

[0015] Furthermore, the detection element includes a gas monitoring structure disposed on the inner wall of the outer sleeve.

[0016] Furthermore, the confluence connection tube has a third interface for connecting to the second interface after the needle core leaves the intermediate connector.

[0017] Furthermore, multiple third interfaces are provided, and each third interface can be connected to a second interface of one of the intermediate connectors.

[0018] Furthermore, the end of the junction connection pipe furthest from the third interface is inserted into the bidirectional gas delivery mechanism.

[0019] Furthermore, the bidirectional gas delivery mechanism is equipped with a pressure sensing module.

[0020] This utility model brings at least the following beneficial effects:

[0021] This utility model provides a percutaneous endotracheal intubation bundled rescue device, comprising: a tracheal puncture cannula assembly, the tracheal puncture cannula assembly including a needle core and an outer cannula, the outer cannula being disposed outside the needle core, the needle core being used for percutaneous puncture and guiding the outer cannula into the trachea; a manifold connecting tube, the manifold connecting tube being able to achieve gas communication with the outer cannula; and a bidirectional gas delivery mechanism, the bidirectional gas delivery mechanism being connected to the manifold connecting tube, for bidirectional gas exchange with the manifold connecting tube.

[0022] The tracheotomy cannula assembly employs a double-layer structure. The inner layer is the needle core, which guides the outer cannula into the trachea. After the outer cannula enters the trachea, the needle core is withdrawn, establishing gas communication between the manifold and the outer cannula. At this point, because the manifold is connected to the bidirectional gas delivery mechanism, bidirectional gas exchange is possible. Oxygen from the bidirectional ventilation mechanism can enter the child's airway through the manifold and the outer cannula to provide ventilation, while carbon dioxide and other gases produced by the child's respiration can also enter the bidirectional gas delivery mechanism through the outer cannula and the manifold.

[0023] This application simplifies the procedure, reducing its reliance on the skills and experience of the operating physician. Medical staff, after professional training, can quickly master the key points of the procedure, enabling rapid establishment of an artificial airway in pediatric emergency care with a high success rate. The percutaneous endotracheal intubation bundle resuscitation device causes minimal damage to the trachea and neck tissues, reducing the incidence of postoperative complications such as bleeding, infection, and tracheal stenosis. The percutaneous endotracheal intubation bundle resuscitation device can effectively provide short-term airway ventilation in emergency situations, buying time for subsequent resuscitation, reducing the incidence of brain injury, and improving the success rate of resuscitation for pediatric patients with difficult airways.

[0039] Example 1

[0040] When performing emergency resuscitation on pediatric patients with difficult airways, it is impossible to perform endotracheal intubation, cricothyroid membrane puncture, or tracheotomy. Airway ventilation cannot be achieved in a short time, resulting in a high incidence of brain injury and seriously affecting the life safety of the children.

[0041] In view of this, the present invention provides a percutaneous tracheal intubation bundled rescue device, comprising: a tracheal puncture cannula assembly 100, the tracheal puncture cannula assembly 100 including a needle core 110 and an outer cannula 120, the outer cannula 120 being disposed outside the needle core 110, the needle core 110 being used for percutaneous puncture and guiding the outer cannula 120 into the trachea; a manifold connecting tube 200, the manifold connecting tube 200 being able to achieve gas communication with the outer cannula 120; and a bidirectional gas delivery mechanism 300, the bidirectional gas delivery mechanism 300 being connected to the manifold connecting tube 200, and being used for bidirectional gas exchange with the manifold connecting tube 200.

[0042] The tracheotomy cannula assembly 100 has a double-layer structure. The inner layer is the needle core 110, which guides the outer cannula 120 into the trachea. After the outer cannula 120 enters the trachea, the needle core 110 is withdrawn, allowing gas communication between the manifold 200 and the outer cannula 120. At this time, since the manifold 200 is connected to the bidirectional gas delivery mechanism 300, bidirectional gas exchange is possible. Oxygen from the bidirectional ventilation mechanism can enter the child's airway through the manifold 200 and the outer cannula 120 to achieve ventilation. Carbon dioxide and other gases produced by the child's breathing can also enter the bidirectional gas delivery mechanism 300 through the outer cannula 120 and the manifold 200.

[0043] This application simplifies the procedure, reducing its reliance on the skills and experience of the operating physician. Medical staff, after professional training, can quickly master the key points of the procedure, enabling rapid establishment of an artificial airway in pediatric emergency care with a high success rate. The percutaneous endotracheal intubation bundle resuscitation device causes minimal damage to the trachea and neck tissues, reducing the incidence of postoperative complications such as bleeding, infection, and tracheal stenosis. The percutaneous endotracheal intubation bundle resuscitation device can effectively provide short-term airway ventilation in emergency situations, buying time for subsequent resuscitation, reducing the incidence of brain injury, and improving the success rate of resuscitation for pediatric patients with difficult airways.

[0044] It should be noted that the technical solution provided in this embodiment is mainly applicable to preventive short-term ventilation and short-term ventilation during emergency rescue. It should be replaced with other more reliable airway control methods as soon as possible.

[0045] In this embodiment, the needle core 110 is made of thin-diameter, sharp-tipped medical-grade stainless steel, which reduces puncture resistance and minimizes tissue damage. The outer cannula 120 is made of soft, biocompatible silicone, which reduces irritation and damage to the tracheal mucosa, promotes postoperative recovery, and has minimal impact on growth and development. The outer diameters of the outer cannula 120 and needle core 110 are designed in various specifications according to the pediatric tracheal diameter. The shapes of the outer cannula 120 and needle core 110 include, but are not limited to, straight, Y-shaped, and arc-shaped. The lengths of the outer cannula 120 and needle core 110 include, but are not limited to, different lengths, taking into full account the depth of the tracheal lining from the anterior neck skin in different pediatric patients.

[0046] In an optional embodiment, the percutaneous endotracheal intubation bundle rescue device further includes an intermediate connector 400. The two ends of the intermediate connector 400 are respectively provided with a first interface 410 and a second interface 420. The needle core 110 and the outer sheath 120 are both connected to the first interface 410. The intermediate connector 400 has a cavity structure. The second interface 420 is used to allow the needle core 110 to leave the intermediate connector 400 and connect to the junction connection tube 200.

[0047] Please see Figure 2 The intermediate connector 400 has a hollow interior, enabling ventilation. Both the needle core 110 and the outer tube 120 are connected to the first interface 410. After the needle core 110 guides the outer tube 120 into the trachea, it exits through the cavity of the intermediate connector 400 from the second interface 420 at the other end, leaving the flexible outer tube 120 in the child's airway. This allows for bidirectional ventilation via the outer tube 120, intermediate connector 400, confluence connector 200, and bidirectional air delivery mechanism 300 within a short period.

[0048] In an optional embodiment, the intermediate connector 400 is provided with fixing wings 430 on both sides, which are used to fit and fix to the human neck when the needle core 110 is punctured.

[0049] Please see Figure 2 The fixation wing 430 can be made of a soft and biocompatible material. When the needle core 110 is punctured and withdrawn, the fixation wing 430 can fit and fix itself to the human neck, providing support.

[0050] In an optional embodiment, the tracheal puncture cannula assembly 100 is provided with a detection element 130, which is used to detect the puncture site of the needle core 110.

[0051] The detection element 130 can detect whether the tracheal puncture cannula assembly 100 has been punctured into the tracheal lumen, effectively improving the stability, accuracy and safety of the intubation, thus buying time for rescue.

[0052] As an alternative, the detection element 130 includes a probe disposed on the needle core 110, and the probe is signal-connected to an external display device.

[0053] The probe can be installed at the end of the needle core 110, and is inserted and withdrawn synchronously with the needle core 110. The probe transmits real-time images back to an external display device, allowing the doctor to determine whether the puncture has been completed and entered the child's trachea. The external display device can be a monitor or a small electronic display device such as a mobile phone, as long as it can establish communication with the probe and display the images transmitted by the probe in real time; there are no restrictions here.

[0054] Alternatively, the detection element 130 includes a gas monitoring structure disposed on the inner wall of the outer sleeve 120.

[0055] The gas monitoring structure can employ a miniature gas detector to monitor indicators such as CO2 partial pressure, CO2 concentration, and oxygen content to determine whether the puncture was successful. Alternatively, the gas monitoring structure can connect a small ventilation tube to a small balloon. When the tracheal puncture cannula assembly 100% is successfully inserted into the tracheal lumen, the balloon inflates due to the airflow through the small ventilation tube, providing a direct visual indication of successful puncture. Furthermore, the gas monitoring structure can also incorporate intelligent early warning devices to achieve intelligent warning functions.

[0056] In an optional embodiment, the junction connection tube 200 has a third interface 210, which is used to connect to the second interface 420 after the needle core 110 leaves the intermediate connector 400.

[0057] Please see Figure 1 After the needle core 110 retracts and exits the intermediate connector 400, the third interface 210 can be connected to the second interface 420 to connect the connecting tube 200 to the intermediate connector 400, and then to the outer tube 120 to achieve ventilation. The shape of the connecting tube 200 includes, but is not limited to, T-shape, Y-shape, and L-shape.

[0058] Furthermore, multiple third interfaces 210 are provided, and each third interface 210 can be connected to a second interface 420 of an intermediate connector 400.

[0059] Please see Figure 1 Multiple endotracheal cannula assemblies 100 and intermediate connectors 400 can be connected to the corresponding third interfaces 210 simultaneously, depending on the child's actual condition, as long as the model and size match. This setup integrates multiple independent, fine airways to achieve a ventilation effect similar to a coarse, single-channel system, thereby effectively establishing airways for pediatric patients with difficult airways.

[0060] In an optional embodiment, the end of the junction connection pipe 200 away from the third interface 210 is inserted into the bidirectional gas delivery mechanism 300, which is equipped with a pressure sensing module.

[0061] Please see Figure 1 The bidirectional gas delivery mechanism 300 provides effective bidirectional gas exchange through airflow dynamics, hemodynamics, and positive and negative pressure principles. This includes, but is not limited to, electric, manual, and automatic pressure sensing devices. A thorough assessment of the child's condition is necessary to select the bidirectional gas delivery mechanism 300 that offers the lowest ventilation resistance and optimal ventilation effect. The safe and efficient bidirectional gas delivery mechanism 300 effectively enables coordinated ventilation of multiple endotracheal cannula assemblies 100, and is the core component for improving the performance of percutaneous endotracheal intubation devices.

[0062] The operation of the percutaneous endotracheal intubation bundled rescue device in this embodiment is optimized, improving the accuracy and safety of operation. It can be successfully implemented in emergency rescue of pediatric children with difficult airways, making it of great application value in pediatric clinical applications.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
