Abstract
Description
Technical Field
[0001] This utility model relates to endotracheal intubation, and more particularly to an endotracheal intubation breathing port cap assembly. Background Technology
[0002] Endotracheal intubation is the insertion of an endotracheal tube through the mouth or nose into the patient's trachea to assist breathing, relieve airway obstruction, and suction tracheal secretions.
[0003] During endotracheal intubation, after the tube is successfully inserted into the patient's trachea, the end remaining outside the body is an open opening, i.e., the breathing opening. While this open design allows the patient to breathe spontaneously or be connected to a ventilator, it also introduces potential safety hazards. One of the most significant risks is the possibility of foreign body aspiration. Foreign body aspiration can lead to a series of serious complications. For example, it can cause acute respiratory distress because the foreign body may partially or completely obstruct the airway, affecting normal gas exchange. The presence of the foreign body may irritate the respiratory mucosa, leading to a violent coughing reflex, which not only increases patient discomfort but may also cause physiological stress responses such as increased blood pressure and heart rate. More seriously, foreign body aspiration can lead to lung infections. When foreign substances enter the normally sterile lower respiratory tract, they introduce a large number of bacteria, increasing the risk of infectious diseases such as pneumonia.

[0051] The following describes in detail, with reference to the accompanying drawings, the endotracheal intubation breathing port cap assembly of this utility model.
[0052] Reference Figures 1 to 5 As shown, the endotracheal intubation breathing port cap assembly provided according to the embodiment of the present utility model includes a sleeve 10, a cap 20 and a flexible connecting strip 30.
[0053] Specifically, the socket 10 is adapted to be fitted and fixed onto the shoulder 402 of the breather connector 401. The function of the socket 10 is to securely fix the cap assembly onto the shoulder 402 of the breather connector 401. Exemplarily, the structure of the socket 10 is compatible with the breather connector 401, ensuring a secure fit and preventing loosening or detachment. This socket installation design not only provides ease of installation but also eliminates the need for modifications to the breather connector 401, requiring only the manufacture of the compatible socket 10. The socket 10 should be made of plastic, which is low-cost and suitable for single-use.
[0054] The cap 20 is detachably fitted onto the breathing connector 401 to seal the breathing port of the breathing connector 401. The cap 20 has multiple breathing holes H201 arranged in a matrix. The function of the cap 20 is to seal the breathing port of the breathing connector 401. On the one hand, the cap 20 effectively seals the breathing port to prevent the entry of foreign objects. On the other hand, to avoid affecting the patient's normal breathing, the cap 20 has multiple breathing holes H201 arranged in a matrix. These breathing holes H201 ensure sufficient gas exchange while effectively blocking the entry of larger particles. The matrix arrangement of the breathing holes H201 also ensures that even if some channels are blocked, there are still enough open channels to maintain breathing. The cap 20 should be made of lightweight, non-toxic, and easy-to-clean medical-grade materials to ensure patient comfort and safety.
[0055] One end of the flexible connecting strip 30 is connected to the sleeve 10, and the other end is connected to the outer wall of the cap 20. The flexible connecting strip 30 is made of flexible plastic and connects the sleeve 10 and the cap 20, ensuring that the cap 20 will not separate from the breathing connector 401, reducing the risk of loss or misplacement of the cap 20. Furthermore, the flexibility of the flexible connecting strip 30 allows it to bend freely, enabling the cap 20 to move flexibly when needed, facilitating necessary operations by medical personnel, such as opening the cap 20 for suctioning or medication administration. In addition, when the cap 20 is not needed, it can be easily detached from the breathing connector 401 and flipped to one side without completely detaching from the assembly, making it convenient to use.
[0056] According to the embodiment of this utility model, the endotracheal intubation breathing port cap assembly includes a sleeve 10, a cap 20, and a flexible connecting strip 30. The sleeve 10 is reliably fixed to the shoulder 402 of the breathing connector 401, ensuring that the cap assembly can be quickly installed onto the breathing connector 401. The cap 20 can be detachably placed on the breathing connector 401, sealing the breathing port and significantly reducing the risk of foreign body aspiration. The multiple breathing holes H201 distributed in a matrix on the cap 20 balance breathing needs and protective functions, ensuring normal breathing for the patient while greatly reducing the possibility of foreign objects entering. The flexible connecting strip 30 connects the sleeve 10 and the cap 20, ensuring that the cap 20 will not be lost and providing operational flexibility, making it convenient to open the cap 20 when needed.
[0057] In some embodiments of this utility model, the sleeve 10 includes a closed collar 101, an open collar 102, and a flexible bending portion 103. The closed collar 101 is sleeved on the breathing connector 401 and located above the shoulder 402. The closed collar 101 is a completely closed ring. The inner diameter of the closed collar 101 should be slightly larger than the outer diameter of the breathing connector 401 to ensure that it can be smoothly fitted onto the breathing connector 401.
[0058] An open collar 102 is fitted onto the breathing connector 401 and located below the shoulder 402. This open collar 102 is an openable ring with two ends. When the two ends are connected, it forms a closed state; when the two ends are not connected, it is in an open state. In the open state, it can be easily inserted into the breathing connector 401 through the gap between the two ends. This feature greatly improves the ease of installation of the connector 10. The inner diameter of the open collar 102 should match the diameter below the shoulder 402 of the breathing connector 401 to ensure a secure fixation.
[0059] A flexible bend 103 connects between a portion of the open collar 102 and the closed collar 101, allowing the closed collar 101 to flip relative to the open collar 102. This design greatly increases the flexibility of the connector 10, making it easier to install on the breathing connector 401 and facilitating quick removal of the cap assembly by healthcare personnel when needed. Furthermore, this structure allows it to accommodate breathing connectors 401 of different sizes.
[0060] A detachable connection structure is provided between the two ends of the open collar 102, which is used to connect the two ends of the open collar 102 after it is fitted onto the breathing connector 401, so as to close the open collar 102.
[0061] During installation, first, the closed collar 101 is fitted onto the breathing connector 401. Then, the open collar 102 is fitted onto the breathing connector 401 through the gaps at both ends, ensuring that the closed collar 101 and the open collar 102 are located on the upper and lower sides of the shoulder 402, respectively. Finally, the two ends of the open collar 102 are connected together using a detachable connection structure. In this way, the closed collar 101 and the open collar 102 are located on the upper and lower sides of the shoulder 402, respectively, and cannot detach from the breathing connector 401 while in the fitted state, enabling the cap assembly to be quickly assembled onto the breathing connector 401.
[0062] In this embodiment, the design of the connector 10 fully considers the actual needs of clinical use. Clinically, endotracheal intubation 40 usually requires the use of a metal guidewire. When the metal guidewire is in the endotracheal tube 40, part of it extends from the breathing port and is bent and hooked onto the side wall of the breathing port. Therefore, it is impossible to install the cap assembly in this state. After the endotracheal tube 40 is inserted into the human body, the metal guidewire is removed, and then the cap assembly is installed. The combination of the closed collar 101 and the open collar 102 ensures that the cap assembly can be installed later and ensures that the connector 10 can be firmly fixed on the breathing connector 401 without easily slipping or shifting.
[0063] In one embodiment of the present invention, the detachable connection structure includes a locking hole at one end of the open collar 102 and a buckle 1021 at the other end of the open collar 102. The buckle 1021 is adapted to be engaged into the locking hole H102 to form a fastening connection.
[0064] In this embodiment, the engagement of the snap fastener 1021 and the locking hole H102 allows the open collar 102 to be closed quickly and easily. When the open collar 102 needs to be fitted onto the breathing connector 401, it can be easily opened, its two ends wrapped around the breathing connector 401, and then the snap fastener 1021 can be inserted into the locking hole with a gentle press to achieve a secure seal. This operation method greatly simplifies the installation process. At the same time, this snap fastener 1021 design also facilitates disassembly. When the cap assembly needs to be removed, medical personnel only need to gently pull both ends of the open collar 102 to disengage the snap fastener 1021 from the locking hole H102, easily detaching the connection.
[0065] In some embodiments of this invention, the surface of the cap 20 is coated with an antibacterial coating containing a metal-based antibacterial agent. The thickness of the metal-based antibacterial layer is generally between 0.01 mm and 0.05 mm.
[0066] Metal-based antibacterial agents for antibacterial coatings can include nano-silver particles, zinc oxide, copper, and copper compounds. Nano-silver particles are a widely used antibacterial agent. They possess a strong antibacterial spectrum, effectively combating a variety of bacteria, fungi, and viruses. The antibacterial mechanism of nano-silver particles primarily involves releasing silver ions, which disrupt the cell membrane and DNA structure of microorganisms, thereby achieving a bactericidal effect. Due to their extremely small particle size, nano-silver can be uniformly distributed within the coating, providing a long-lasting antibacterial effect.
[0067] Zinc oxide is another commonly used metal-based antibacterial agent. It possesses excellent antibacterial properties; its antibacterial mechanism primarily involves generating reactive oxygen species, which disrupt the cell structure of microorganisms. Furthermore, zinc oxide also exhibits some anti-inflammatory effects.
[0068] Copper and copper compounds are also effective antibacterial agents. Copper ions can interfere with the metabolic processes of microorganisms, inhibiting their growth and reproduction. Copper's antibacterial effect is long-lasting, maintaining good antibacterial properties even after long-term use. Some copper compounds, such as cuprous oxide, also have stronger antibacterial activity.
[0069] In this embodiment, the application of the antibacterial coating provides infection protection for the cap 20, preventing problems such as easy growth of bacteria on the cap 20 and improving safety.
[0070] In some embodiments of this utility model, the cap 20 is provided with an oxygen inhalation connector 201 for connecting an external oxygen inhalation tube.
[0071] In some cases, intubated patients may require additional oxygen supply. Traditionally, this requires a separate oxygen device, which not only increases the complexity of the equipment around the bed but can also cause additional discomfort to the patient. However, with an oxygen connector 201 directly integrated into the cap 20, the oxygen supply tube can be directly connected, eliminating the need for a separate oxygen tube or other oxygen device worn over the nose. This greatly facilitates oxygen administration for intubated patients.
[0072] In one embodiment of this utility model, the inner circumferential surface of the cap 20 has a stepped surface S201, which stops at the end face of the breathing connector 401. The outer circumferential surface of the cap 20 is provided with a circumferentially extending cheek hole H202, which is located between the stepped surface S201 and the inner top surface of the cap 20 and communicates with the breathing connector 401.
[0073] In this embodiment, the main function of the stepped surface S201 is to precisely stop the cap 20 on the end face of the breathing connector 401 when it is installed onto the cap 20, ensuring accurate positioning of the cap 20 during installation and preventing over-insertion. The cheek hole H202 provides an additional gas exchange channel, further ensuring smooth breathing for the patient. Furthermore, since the cheek hole H202 is located on the outer peripheral surface of the cap 20, it is generally less likely to be blocked, thus ensuring the reliability and safety of the cap assembly's breathing function. In addition, the cheek hole H202 can reduce breathing resistance and improve patient comfort.
[0074] Preferably, the inner circumferential surface of the cap 20 is provided with an annular groove, and a sealing ring for contacting the outer circumferential surface of the breathing connector 401 is engaged in the annular groove. When the cap 20 is installed on the breathing connector 401, the sealing ring will deform slightly to adapt to the outer surface of the breathing connector 401, thereby ensuring a reliable fit between the two and preventing them from easily falling off.
[0075] In some embodiments of this utility model, the cap 20 is provided with a nanofiber filter screen made using electrospinning technology.
[0076] Because nanofibers have extremely small diameters, typically ranging from 50 to 500 nanometers, they are much smaller than the size of most pathogens and particulate matter. This allows the nanofiber mesh to effectively capture tiny particles in the air, including bacteria, viruses, and other potentially harmful substances, thus significantly improving the filtration efficiency of the cap 20. Furthermore, the porous structure of the nanofiber mesh still maintains good air permeability, ensuring that the patient's breathing is not significantly obstructed and guaranteeing smooth and comfortable breathing.
