Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a spoon-shaped oropharyngeal suction tube. Background Technology

[0002] Suctioning is an invasive procedure that requires inserting a suction catheter into the patient's body. Patients recovering from general anesthesia may experience cardiovascular reactions such as a sudden increase in blood pressure and a significant increase in heart rate due to factors such as the weakening of the anesthetic effect, the return of consciousness, coughing, endotracheal tube irritation, suctioning, and pain. These reactions are especially intense during suctioning.

[0003] Currently, F12-F14 disposable sterile silicone suction catheters are commonly used in clinical practice to suction secretions from the oropharyngeal cavity of patients undergoing general anesthesia resuscitation. However, due to their long tubes, narrow lumen, and flexible and easily bent nature, they are inefficient and inconvenient to operate when suctioning sputum and secretions from the oropharyngeal cavity. Secondly, other existing suction devices, due to unreasonable structural design and material selection, can cause certain irritation or even damage to patients during insertion, resulting in poor patient comfort.

[0004] Therefore, there is an urgent need to propose a more reasonable suction tube design that can at least balance the suction effect and suction efficiency, as well as avoid the problem of poor patient comfort when inserted into the oropharyngeal cavity. Utility Model Content

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0042] This application provides a spoon-shaped oropharyngeal suction tube, which solves the problem that existing suction tubes cannot balance suction effectiveness and patient comfort, and achieves the goal of improving suction effectiveness and efficiency while ensuring patient comfort as much as possible.

[0043] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0044] Currently, disposable sterile silicone suction catheters (F12-F14 type) are commonly used in clinical practice to suction secretions from the oropharyngeal cavity of patients recovering from general anesthesia. However, these catheters are long (40-45cm), narrow (approximately 4.5mm), and flexible, resulting in low efficiency and inconvenient operation when suctioning sputum and secretions from the oropharynx. To address this issue, this application proposes a spoon-shaped oropharyngeal suction catheter, comprising a spoon-shaped silicone suction head, a drainage tube, a connector, and a ventilation port. This spoon-shaped oropharyngeal suction catheter resembles a spoon in shape, with its suction head made of silicone, featuring a concave, hollow design and smooth edges. It can quickly and effectively remove sputum and secretions from the oropharyngeal cavity of patients recovering from general anesthesia, reducing the negative impact of suctioning on these patients, improving their comfort, stabilizing circulation, suppressing coughing, and thus effectively preventing respiratory complications in patients recovering from general anesthesia.

[0045] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0046] See Figure 1-5 This application first proposes a spoon-shaped oropharyngeal suction tube, which includes: a concave and hollow suction head 1, a drainage tube 2, and a connector 3.

[0047] The drainage tube 2 is connected to a suction head 1 and a connector 3 at both ends, and the suction head 1 is provided with several ventilation holes 4. The suction head 1 is used to insert into the patient's oropharyngeal cavity and suction sputum and secretions through the ventilation holes 4. The connector 3 is used to connect to a negative pressure device or other auxiliary suction device or machine.

[0048] The commonly used disposable sterile silicone suction catheters in clinical practice suffer from low suctioning efficiency and are difficult to operate due to their long tube (40cm-45cm), narrow lumen (approximately 4.5mm), and flexible nature. To address these issues, the spoon-shaped oropharyngeal suction catheter in this embodiment includes the following improvements:

[0049] On the one hand, in this embodiment, the drainage tube 2 is made of K resin material. K resin has good strength and toughness, and compared with the soft and flexible silicone suction tubes in the prior art, it has a better suction effect and is easier to operate. At the same time, it can prevent the patient from biting it off or crushing it, which would affect the suction effect. In addition, the drainage tube 2 made of K resin material has good transparency, which makes it easy for medical staff to observe the color, amount and characteristics of oropharyngeal secretions.

[0050] On the other hand, in this embodiment, the suction head 1, which is connected to one end of the drainage tube 2 and is used to insert into the patient's oropharyngeal cavity to aspirate sputum and secretions, is concave in shape and has a hollow internal structure with several ventilation holes 4 distributed on it. Through the ventilation holes 4, sputum and secretions in the patient's oropharyngeal cavity can be aspirated into the suction head 1 and then drained out through the drainage tube 2.

[0051] The connector 3, which is connected to the other end of the drainage tube 2, is used to connect to a negative pressure device or other auxiliary suction device or machine. Utilizing the principle of negative pressure, the suction tube can easily, quickly, and conveniently suction sputum and secretions from the patient's oropharyngeal cavity.

[0052] To address the problems of poor suctioning effect and inconvenient operation caused by excessively long tubing in existing suctioning catheters, a spoon-shaped oropharyngeal suctioning catheter is proposed with a total length of 20-25 cm and an outer diameter of 6-8 mm and an inner diameter of 4-6 mm for the drainage tube. Preferably, in this embodiment, the spoon-shaped oropharyngeal suctioning catheter has a total length of 22 cm, which is a suitable length for easy operation, and the drainage tube has an outer diameter of 8 mm and an inner diameter of 6 mm, resulting in better suctioning effect. Specifically... Figure 5 As shown.

[0053] Furthermore, to balance suction effectiveness and patient comfort, the overall length of the suction head is 3–3.5 cm, the connecting length is 0.8–1.2 cm, and the spoon head length is 2–2.5 cm. Preferably, in this embodiment, the overall length of the suction head 1 is 3.5 cm, which is a more suitable size when inserted into the patient's oropharyngeal cavity, balancing patient comfort and suction effectiveness. Specifically, as follows... Figure 5As shown.

[0054] The suction head 1 includes a connecting portion 11 connected to one end of the drainage tube 2 and a concave and hollow spoon head 12 connected to the other end of the connecting portion 11. In this embodiment, the shape of the spoon head 12 of the suction head 1 is not specifically limited; it can be a hollow hemispherical shell with a circular cross-section, a hollow semi-ellipsoidal shell with an elliptical cross-section, or a shell with a regular polygonal cross-section, or other shapes that can achieve the same or similar functions as the aforementioned hollow hemispherical shell or hollow semi-ellipsoidal shell. See details for further information. Figure 1-4 .

[0055] For example, in one embodiment, the overall shape of the suction head 1 resembles a ping-pong paddle. The connecting portion 11 is 1 cm long, similar to the handle of a ping-pong paddle, and the spoon head 12 is a concave and hollow hemispherical shell with a circular cross-section, the diameter of which is 2.5 cm. Specifically... Figure 1 As shown.

[0056] In another embodiment, the suction head 1 is generally semi-ellipsoidal, including a connecting part 11 connected to the drainage tube 2 and a spoon head 12, a concave and hollow semi-ellipsoidal shell connected to the other end of the connecting part 11. The major axis of the ellipse corresponding to the largest elliptical cross-section of the semi-ellipsoid is 3-3.5 cm, preferably 3.2 cm, and the minor axis is 1.8-2 cm, preferably 2 cm. The drainage tube 2 is continuously connected to one end of the semi-ellipsoidal shell containing the major axis. In actual operation, the connecting part 11 and the spoon head 12 can be separately or integrated. See details... Figure 2 and Figure 4 .

[0057] Furthermore, the spoon head 12 of the suction head 1 is made of medical-grade silicone material, and its edges are smooth, soft and comfortable, so that the patient's oral mucosa will not be damaged when the suction head 1 is inserted into the patient's oropharyngeal cavity.

[0058] To improve suctioning efficiency, the concave surface of the spoon head 12 of the suction head 1 has several staggered ventilation holes 4. In one embodiment, the concave surface of the spoon head 12 has five circular ventilation holes 4 with a diameter of 0.3 cm. However, in specific implementations, the number, diameter, shape, and distribution of the ventilation holes 4 are not specifically limited. For example, they can also be elongated holes that are parallel to the diameter (or minor axis) of the largest cross-section of the spoon head 12 (circular or elliptical) and evenly distributed.

[0059] Furthermore, several side suction holes 5 are distributed on both sides of the front edge of the spoon. These side suction holes 5, together with the ventilation holes 4 on the surface of the spoon head 12, can further enhance the suctioning effect. See details... Figure 4In one embodiment, preferably, the side suction hole is a circular hole with a diameter of 0.3 cm, and the distance between adjacent side suction holes is 0.5 cm.

[0060] In another embodiment, to further ensure the suctioning effect, the spoon head 12 of the suction head 1 is rotated counterclockwise by a certain angle α based on the extension direction of the drainage tube 2, where angle α is 15-20°. The upward angle of the spoon head 12, combined with its concave shape, allows for scraping and collection of sputum and secretions from the patient's oropharynx during suctioning. Combined with the ventilation port 4, this further enhances the suctioning effect. See details... Figure 4 .

[0061] Furthermore, in one embodiment, in order to further improve the suctioning effect of the spoon-shaped oropharyngeal suction tube, the upward tilt angle α of the spoon head 12 of the suction head 1 is 20°.

[0062] The method of use and principle of the spoon-shaped oropharyngeal suction catheter proposed in this application are as follows:

[0063] When using the above-mentioned spoon-shaped oropharyngeal suction tube, first connect the connector 3 directly to the negative pressure suction device. Then, the medical staff gently inserts the front end of the suction tube into the patient's oral pharynx and cheek. The left thumb blocks the negative pressure hole on the connector 3, and the right hand quickly rotates and pulls upward to gently scrape the patient's oral pharynx, causing secretions to shift. At the same time, the concave structure of the spoon head 12 is used to gather and collect sputum and other secretions. Then, the negative pressure principle is used to smoothly suction the sputum and other secretions into the oropharynx.

[0064] In summary, compared with existing technologies, it has the following beneficial effects:

[0065] 1. This application discloses a spoon-shaped oropharyngeal suction tube comprising: a concave and hollow suction head, a drainage tube, and a connector; wherein the two ends of the drainage tube are respectively connected to the suction head and the connector, and the suction head is provided with several ventilation holes. This spoon-shaped oropharyngeal suction tube can quickly suction out thick sputum and secretions from different locations in the patient's oropharynx, shortening the time for a single suction, improving work efficiency, and reducing the workload of nurses.

[0066] 2. The spoon-shaped oropharyngeal suction tube proposed in this application has a spoon head that rotates counterclockwise and tilts upward at a certain angle based on the extension direction of the drainage tube, similar to the spoon head of a spoon. During the suction process, it can scrape and collect sputum and secretions in the patient's oropharyngeal cavity. Combined with the ventilation hole, it can significantly improve the suction effect.

[0067] 3. The spoon-shaped oropharyngeal suction tube proposed in this application has several ventilation holes and side suction holes distributed on its suction head, which can effectively improve the suction effect.

[0068] 4. The spoon-shaped oropharyngeal suction tube proposed in this application is made of K resin material. Compared with the soft and flexible silicone suction tube in the prior art, it has good strength and toughness and is easier to operate. At the same time, the drainage tube made of K resin material has good transparency, which makes it easy for medical staff to observe the color, amount and nature of oropharyngeal secretions.

[0069] 5. The spoon-shaped oropharyngeal suction tube proposed in this application has a spoon head made of medical-grade silicone material with smooth, soft and comfortable edges. It can move the suction head into the patient's oropharyngeal cavity without damaging the patient's oral mucosa, thus improving the patient's comfort.
