Description

Technical Field

[0001] The utility model relates to the field of medical instruments and provides a tracheal cannula component. Background Art

[0002] Tracheal intubation is an important basic technical skill in emergency medicine, critical care medicine, anesthesia medicine, etc. It is of great significance for reconstructing the respiratory tract, conducting effective artificial or mechanical ventilation, preventing hypoxia and carbon dioxide retention, clearing respiratory secretions or foreign bodies, administering drugs into the airway, safe transportation, ensuring successful rescue, reducing mortality, and improving prognosis.

[0003] The main medical devices required for endotracheal intubation include an endotracheal tube and a guide core. The existing guide core is a thin guide wire. Since the diameter of the guide wire is very thin, relative shaking between the guide wire and the endotracheal tube is very easy to occur. Therefore, during intubation, the direction of the endotracheal tube is difficult to control, which can easily lead to the endotracheal tube being mistakenly inserted into the esophagus. Moreover, due to the low structural strength of the endotracheal tube, it is difficult to insert it into the trachea of ​​patients with laryngeal edema. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the related art. To this end, the utility model proposes an endotracheal tube assembly,

[0005] The utility model provides an endotracheal tube assembly, comprising:

[0006] An endotracheal tube body, wherein a ventilation space is formed in the endotracheal tube body, and the end of the second end of the endotracheal tube body is a flat end;

[0040] like Figures 1 to 5 As shown, the utility model embodiment provides a tracheal intubation assembly, comprising:

[0041] The endotracheal tube body 100 has a ventilation space formed therein, and the end of the second end of the endotracheal tube body 100 is a flat end;

[0042] The guide core 102 is inserted into the ventilation space and both ends of the guide core 102 extend out of the ventilation space respectively;

[0043] A mounting seat 104 is disposed at the first end of the endotracheal tube body 100, and a connecting hole 106 is disposed on the mounting seat 104;

[0044] The connector 108 is disposed at the first end of the guide core 102 . A clamping portion 110 is disposed on the connector 108 . The clamping portion 110 is detachably connected to the connecting hole 106 . When the clamping portion 110 is connected to the connecting hole 106 , the first end of the guide core 102 is connected to the first end of the endotracheal tube body 100 .

[0045] According to the endotracheal tube assembly provided by the embodiment of the first aspect of the utility model, by inserting the guide core 102 into the ventilation space of the endotracheal tube body 100, and extending the two ends respectively, the guide core 102 can effectively play a guiding role during the endotracheal tube, so that the endotracheal tube body 100 can be inserted into the target position more accurately. This design is particularly important for operating in a complex or narrow space, which can reduce the difficulty of operation and improve the accuracy and success rate of operation. The detachable design between the clamping part 110 on the connector 108 and the connecting hole 106 on the mounting seat 104 makes the connection between the guide core 102 and the endotracheal tube body 100 fast and convenient. This design is not only convenient for medical staff to use, but also can greatly save time and improve work efficiency when the endotracheal tube assembly needs to be replaced or cleaned. Due to the close combination of the clamping part 110 and the connecting hole 106, the guide core 102 and the endotracheal tube body 100 can maintain a stable structure after connection. This stability ensures that during use, the endotracheal tube assembly will not loosen, relatively shift or fall off due to vibration or other external factors, ensuring the safety and reliability of use. Both ends of the guide core 102 extend out of the ventilation space, which allows medical staff to flexibly adjust the position and angle of the guide core 102 as needed during operation to adapt to different operational requirements. At the same time, the flat-end design of the second end also makes it easier to insert the endotracheal tube body 100 into the target position. Since the various components of the endotracheal tube assembly are detachable, they can be reused after cleaning and disinfection, which reduces medical costs and is also in line with environmental protection concepts.

[0046] Please continue to see Figures 1 to 5 One of the core components of the endotracheal tube assembly is the endotracheal tube body 100. The endotracheal tube body 100 is a tubular component with a specific structure, and a ventilation space is formed inside the endotracheal tube body 100 to provide a necessary breathing passage for the patient during the medical treatment. It is particularly noteworthy that the end of the second end of the endotracheal tube body 100 is designed to be flat, which helps to reduce the resistance during the insertion process and improve the smoothness of the operation.

[0047] Secondly, the endotracheal tube assembly also includes a guide core 102, which is designed to be inserted into the ventilation space of the endotracheal tube body 100, and both ends of the guide core 102 can extend out of the ventilation space. The presence of the guide core 102 can greatly improve the positioning accuracy of the endotracheal tube body 100, so that it can be more accurate and stable when inserted into the patient's airway.

[0048] Furthermore, the endotracheal tube assembly is further provided with a mounting seat 104, which is arranged at the first end of the endotracheal tube body 100 and has a connecting hole 106. The mounting seat 104 mainly provides a connection point for connecting the endotracheal tube body 100 with other related components.

[0049] Finally, the assembly also includes a connector 108. The connector 108 is disposed at the first end of the guide core 102, and a clamping portion 110 is disposed thereon. The clamping portion 110 can be detachably connected to the connection hole 106 on the mounting seat 104. When the clamping portion 110 is successfully connected to the connection hole 106, the first end of the guide core 102 is also successfully connected to the first end of the endotracheal tube body 100. This connection method is both stable and easy to operate, and can greatly improve the work efficiency of medical staff. In this way, when the endotracheal tube body 100 is inserted into the patient's trachea, the structural strength of the endotracheal tube body 100 can be improved by the guide core 102, and shaking during the insertion of the endotracheal tube body 100 into the patient's trachea can be avoided.

[0050] In general, the endotracheal tube assembly provided in the embodiment of the utility model realizes efficient and stable operation of endotracheal tube through the ingenious design of the endotracheal tube body 100, the guide core 102, the mounting seat 104 and the connector 108, which is of great significance for improving medical quality and ensuring patient safety.

[0051] According to an embodiment of the present invention, there are at least two connecting holes 106 , and the at least two connecting holes 106 are symmetrically arranged relative to the center line of the mounting seat 104 , and the clamping portions 110 are arranged in a one-to-one correspondence with the connecting holes 106 .

[0052] The number of the connecting holes 106 is at least two, and the connecting holes 106 are symmetrically arranged relative to the center line of the mounting base 104. Such a design has two main advantages.

[0053] First, by providing at least two connection holes 106 and symmetrically distributing these connection holes 106, it is possible to ensure that the endotracheal tube assembly has higher stability and balance during connection. This symmetrical design helps to reduce possible deviation or distortion during the connection process, thereby improving the reliability and safety of the entire assembly.

[0054] Secondly, the clamping parts 110 are arranged in a one-to-one correspondence with the connecting holes 106, which means that each connecting hole 106 has a matching clamping part 110. This design makes the connection process more accurate and efficient. Medical staff can clearly see the position of each connecting hole 106 and accurately insert the clamping part 110 into the corresponding connecting hole 106, thereby simplifying the operation steps and improving work efficiency.

[0055] In addition, the symmetrically arranged connection holes 106 can also increase the flexibility and adaptability of the endotracheal tube assembly. According to different usage scenarios and patient needs, different numbers of connection holes 106 can be selected for connection to meet different medical needs.

[0056] According to an embodiment of the present invention, the clamping portion 110 includes:

[0057] A connecting rod 112, one end of which is connected to the connecting head 108;

[0058] The clamping joint 114 is formed at one end of the connecting rod 112 away from the connecting head 108 , and the clamping joint 114 is detachably connected to the connecting hole 106 .

[0059] The clamping portion 110 mainly consists of two parts: a connecting rod 112 and a clamping joint 114 .

[0060] First, one end of the connecting rod 112 is connected to the connector 108. The function of the connecting rod 112 is to connect the connector 108 with the clamping joint 114 to form an integral structure. Such a design makes the connection between the guide core 102 and the endotracheal tube body 100 more stable and not easy to loosen.

[0061] Secondly, the clamping joint 114 is formed at the end of the connecting rod 112 away from the connecting head 108. The clamping joint 114 is designed to be detachably connected to the connecting hole 106. This means that when the guide core 102 needs to be connected to the endotracheal tube body 100, the clamping joint 114 only needs to be aligned with the connecting hole 106 and inserted to achieve the connection; and when it needs to be disassembled, the clamping joint 114 only needs to be simply pulled out from the connecting hole 106. This design makes the operation very simple and quick, and also improves the flexibility of assembly.

[0062] In practical applications, the shape and size of the card connector 114 can be adjusted according to the specific design of the connection hole 106 to ensure the matching and stability between the two. At the same time, some locking mechanisms or fasteners can be used between the card connector 114 and the connection hole 106 to further enhance the firmness of the connection and prevent it from falling off or loosening during use.

[0063] According to an embodiment of the present invention, a supporting boss 116 is formed on the connecting rod 112 , and the supporting boss 116 protrudes toward the guide core 102 .

[0064] A support boss 116 is formed on the connecting rod 112, and the boss protrudes toward the guide core 102. By providing the support boss 116, when the medical staff needs to remove the card connector 114 from the connecting hole 106, the support boss 116 and the connecting rod 112 can form a lever-like structure, which is convenient for the medical staff to apply a relatively small force to remove the card connector 114 from the connecting hole 106. Similarly, when the card connector 114 needs to be installed in the connecting hole 106, the medical staff only needs to press the connecting rod 112 to a certain extent so that the card connector 114 passes through the connecting hole 106.

[0065] According to an embodiment of the present invention, when the clamping joint 114 is connected to the connecting hole 106 , a gap is formed between the supporting boss 116 and the mounting seat 104 .

[0066] Specifically, when the card connector 114 is successfully connected to the connecting hole 106, a gap is formed between the supporting boss 116 and the mounting seat 104. The supporting boss 116 and the mounting seat 104 interact with each other, and the combination of 114 and 106 is more firm.

[0067] The existence of such a gap has several important meanings. First, the gap can ensure that the support boss 116 has sufficient space to move on the mounting seat 104, thereby avoiding difficulty in connection or damage to the mounting seat 104 due to overly tight contact during the connection process. At the same time, the gap can also play a buffering role, reducing the impact caused by external forces and protecting the various components of the endotracheal tube assembly.

[0068] Secondly, the existence of the gap is also helpful to reduce friction and wear. During the use of the endotracheal tube assembly, a certain relative movement may occur between the support boss 116 and the mounting seat 104. If the contact between the two is too close, friction and wear will increase, affecting the service life of the assembly. The existence of the gap can reduce such friction and wear and extend the service life of the assembly.

[0069] In addition, the gap can also improve the plugging and unplugging flexibility of the card connector 114. Since there is a certain gap between the support boss 116 and the mounting seat 104, medical personnel can more easily pull it out of the connecting hole 106 when they need to remove the card connector 114, thereby improving the convenience of operation.

[0070] According to one embodiment of the present invention, the guide core 102 includes:

[0071] Core column 118;

[0072] The sheet body 120 is disposed on the core column 118 in a divergent shape with the core column 118 as the center.

[0073] The stem 118, as the main body of the guide core 102, plays a supporting and stabilizing role. It is strong and durable, and can ensure sufficient rigidity and stability when inserted into the patient's airway.

[0074] The sheet 120 is arranged on the core column 118 in a divergent shape with the core column 118 as the center. The existence of the sheet 120 not only increases the overall surface area of ​​the guide core 102, but also enables the guide core 102 to better contact the airway wall when inserted into the airway, thereby improving the positioning accuracy and stability of the guide core 102.

[0075] In practical applications, the guide core 102 of this structure can better adapt to airways of different shapes and sizes, making the tracheal intubation process smoother and more efficient. At the same time, the divergent design of the sheet body 120 can also reduce the resistance during insertion to a certain extent, improving the comfort of the patient.

[0076] According to an embodiment of the present invention, an end portion of the sheet body 120 located at the second end of the guide core 102 is formed with an arc chamfer.

[0077] Specifically, an end portion of the sheet body 120 located at the second end of the guide core 102 forms an arc-shaped chamfer.

[0078] This curved chamfer design has multiple advantages in practical applications. First, the presence of the curved chamfer can significantly reduce the resistance when inserting into the patient's airway. Compared with sharp corners, the curved chamfer is smoother and can pass through the airway more smoothly, reducing the patient's discomfort.

[0079] Secondly, the arc chamfer can also increase the contact area between the sheet 120 and the airway wall, thereby improving the positioning accuracy of the guide core 102. When the guide core 102 is inserted into the airway, the arc chamfer can better fit the shape of the airway wall, ensuring that the guide core 102 can stay stably at the predetermined position to prevent slipping or displacement.

[0080] In addition, the design of the arc chamfer also has certain safety considerations. In medical operations, sharp corners may cause unnecessary damage to patients. The arc chamfer can reduce this risk and protect the safety of patients.

[0081] According to an embodiment of the present invention, the number of the sheets 120 is 3 to 8.

[0082] First, 3 to 8 sheets 120 can ensure that the guide core 102 has sufficient stability and support when inserted into the airway. Too few sheets 120 may lead to insufficient support, while too many sheets 120 may increase insertion resistance and operational difficulty. Therefore, selecting the number of sheets 120 within this range can achieve a balance between stability and operational convenience.

[0083] Secondly, this design range also takes into account individual differences in patients and differences in airway structures. The airway size and shape of different patients may be different. Therefore, by adjusting the number of sheets 120, it is possible to better adapt to the airway structure of different patients and improve the success rate and safety of tracheal intubation.

[0084] In addition, this design range also takes into account the feasibility of manufacturing. Under the premise of ensuring performance, by reasonably designing the number of sheets 120, the production cost can be reduced, the production efficiency can be improved, and the endotracheal tube assembly can be made more economical and practical.

[0085] According to an embodiment of the present invention, the angular intervals between two adjacent sheets 120 are equal.

[0086] Specifically, the angular intervals between two adjacent sheets 120 are designed to be equal. This design brings several significant advantages. First, the layout of equal angular intervals makes the sheets 120 more evenly distributed on the guide core 102, thereby enhancing the stability and balance of the overall structure. When inserted into the airway, the evenly distributed sheets 120 can better adapt to the shape of the airway, reduce the resistance during insertion, and improve the accuracy of positioning.

[0087] Secondly, the design of equal angle intervals also helps to simplify the production process. During the manufacturing process, the sheet 120 can be accurately positioned and fixed by standardized angle intervals, which improves production efficiency and reduces manufacturing difficulty.

[0088] In addition, the layout of equal angle intervals can also reduce the jamming or twisting that may occur during the insertion process. Since the angle intervals between the sheets 120 are uniform, they can work more harmoniously, reduce unnecessary friction and resistance, and make the tracheal intubation process smoother.

[0089] According to an embodiment of the present invention, a through hole 122 is defined on the mounting seat 104 , and the guide core 102 is adapted to pass through the through hole 122 and be connected to the connector 108 .

[0090] The main function of the through hole 122 is to allow the guide core 102 to pass through so as to be connected to the connector 108. During the assembly process of the endotracheal tube assembly, the guide core 102 needs to be connected to the connector 108 through the mounting seat 104. By providing the through hole 122 on the mounting seat 104, it can be ensured that the guide core 102 can smoothly pass through the mounting seat 104 and form a stable connection with the connector 108. This design not only simplifies the assembly steps and improves the assembly efficiency, but also ensures the reliability and stability of the connection.

[0091] In addition, the design of the via hole 122 can be adjusted and optimized according to actual needs. For example, the size and shape of the via hole 122 can be customized according to the size and shape of the guide core 102 to ensure that the guide core 102 can pass through the via hole 122 tightly to reduce the possibility of looseness and shaking.

[0092] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
