Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, and in particular relates to a suction tube. Background Technology
[0002] A suction catheter is a medical device used to remove secretions, sputum, or other foreign objects from a patient's airway or trachea. It is typically made of soft materials, such as soft plastic or silicone, to ensure comfort and safety. It generally includes:
[0003] Tubular Section: The main part of the suction catheter is a flexible tubular structure, usually made of materials such as transparent plastic or silicone. This tubular structure has a certain degree of flexibility and curvature to facilitate insertion into the patient's mouth or trachea. Ventilation Hole: One end of the suction catheter usually has a small hole called a ventilation hole. The function of the ventilation hole is to maintain ventilation and prevent the suction catheter from sticking to the mucous membrane, ensuring airflow. Connector: The other end of the suction catheter usually has a connector for connecting the suction catheter to a negative pressure suction device. The connector can have different designs and sizes to accommodate different types of negative pressure suction devices.
[0004] Tube diameter and side hole design: The suction catheter has an appropriate inner diameter and side hole design so that sputum can enter the tube through the side hole and be aspirated when the guide tube is along the airway. When suctioning sputum through the mouth, the side suction port can easily aspirate the mucosa, irritating the respiratory mucosa and causing mucosal bleeding. In clinical application, it has been found that the suction catheter easily aspirates the oral mucosa and causes bleeding. Summary of the Invention

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0028] Sputum suction tube is a medical device used to remove accumulated sputum from the respiratory tract through the mouth or endotracheal tube. Its principle is based on the following aspects:
[0029] Negative pressure principle: One end of the sputum suction tube is connected to a negative pressure source (such as a suction device or a manual suction device). Through the action of negative pressure, sputum is sucked into the sputum suction tube and then extracted out of the body. The generation of negative pressure helps to remove sputum from the respiratory tract.
[0030] Fast suction: Sputum suction tube usually has a larger inner diameter and appropriate length to quickly suck out sputum. This reduces the time of sputum staying in the respiratory tract, effectively removing respiratory tract secretions.
[0031] Tube diameter and side hole design: Sputum suction tube has appropriate inner diameter and side hole design, so that when the guide tube is along the respiratory tract, sputum can enter the tube through the side hole and then be sucked in.
[0032] Softness and flexibility: Sputum suction tube is usually made of soft material, which can adapt to the curved shape of the oral cavity and airway. This softness and flexibility helps to reduce the risk of damage to the patient's tissue and provides better comfort.
[0033] Transparency: Many sputum suction tubes are made of transparent material, allowing medical personnel to clearly observe sputum and secretions produced during the sputum suction process. Transparency can help medical personnel monitor the patient's respiratory tract condition and take appropriate measures in a timely manner.
[0034] Proper size selection: The size of the sputum suction tube can be selected according to the patient's age, body size and clinical needs. Proper size can ensure that the sputum suction tube is inserted into the appropriate position to achieve better sputum suction effect.
[0035] Ventilation port design: One end of the suction catheter is usually equipped with a ventilation port to ensure airflow and prevent the suction catheter from adhering to the respiratory mucosa. The ventilation port design can reduce irritation and damage to the mucosa and provide a better insertion experience. Example
[0036] like Figure 1 As shown, this embodiment is a suction catheter, including a tube body 1 and a connecting connector 5. One or two ventilation holes 101 are provided at one end of the tube body 1. A support structure for separating the tube body 1 from the oral mucosa is provided outside the ventilation holes 101 of the tube body 1. The other end of the tube body 1 is located in a negative pressure chamber, which includes a cavity box 3 and a cavity box cover 4 that is fastened to the cavity box 3.
[0037] like Figure 2 As shown, a connecting part 301 is provided at the end of the cavity body 3, and the cavity cover 4 is fitted onto the connecting part 301. Figure 4 The diagram shows the structure of the cavity cover 4. The cavity cover 4 is a deep cylindrical structure, and the cavity formed can collect sputum.
[0038] The connecting connector 5 is located on the cavity body 3 and is interconnected with the cavity body 3. It is used to connect the suction catheter and the negative pressure suction device. The connecting connector can have different designs and specifications to accommodate different types of negative pressure suction devices.
[0039] The end of the connector 5 is provided with a nozzle 501, and the connector 5 is also provided with an air valve 6 to facilitate the exhaust of air during suction.
[0040] like Figure 3 As shown, the supporting structure is a funnel-shaped opening 2, which covers the end of the tube where the vent 101 is located. By separating the vent 101 from the oral mucosa through the funnel-shaped opening 2, it is possible to effectively prevent negative pressure airflow from passing through the vent 101 and causing damage to the oral mucosa.
[0041] Furthermore, the support structure is an elastic support rod 7 installed at the end of the pipe.
[0042] Furthermore, the elastic support rod 7 is a silicone capillary column structure. Example
[0043] like Figure 1 As shown, this embodiment is a suction catheter, including a tube body 1 and a connecting connector 5. One or two ventilation holes 101 are provided at one end of the tube body 1. A support structure for separating the tube body 1 from the oral mucosa is provided outside the ventilation holes 101 of the tube body 1. The other end of the tube body 1 is located in a negative pressure chamber, which includes a cavity box 3 and a cavity box cover 4 that is fastened to the cavity box 3.
[0044] likeFigure 2 As shown, the end of the cavity box body 3 is provided with a connecting part 301, and the cavity box cover 4 is sleeved on the connecting part 301. Figure 4 As shown, the cavity box cover 4 is a deep cylindrical structure, and the cavity formed can collect sputum.
[0045] The connecting joint 5 is located on the cavity box body 3, and the connecting joint 5 and the cavity box body 3 are mutually penetrated. It is used for connecting the sputum suction tube and the negative pressure suction equipment. The connecting joint can have different designs and specifications to adapt to different types of negative pressure suction equipment.
[0046] The end of the connecting joint 5 is provided with a mouth port 501, and the connecting joint 5 is also provided with an air valve 6, which is convenient for exhausting during suction.
[0047] As shown, Figure 5 The support structure is a capillary elastic support rod 7 uniformly arranged at the pipe end part, and the elastic support rod 7 is a silica gel capillary column structure. The uniform distribution of the capillary elastic support rod 7 separates the air hole 101 from the oral mucosa, which can effectively prevent the negative pressure airflow from causing damage to the oral mucosa through the air hole 101.
[0048] In addition, the uniform distribution of the capillary elastic support rod 7 structure is more easy to use the oral cavity, and is friendly to the internal tissues of the oral cavity.
