Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a fish-mouth saliva drainage pad. Background Technology

[0002] In the practice of preanesthesia medication, the main objectives are to achieve multiple effects, including alleviating patient anxiety, achieving sedation, raising the pain threshold, reducing airway secretions, preventing adverse autonomic reflexes, reducing gastric volume and regulating its pH to a higher level, preventing vomiting, and reducing the dosage of anesthetic drugs and related adverse reactions. To achieve these goals, anticholinergic drugs are often used as adjunctive medications before anesthesia. These drugs effectively inhibit the activity of various smooth muscles and glandular secretions by blocking cholinergic receptors on effectors controlled by postganglionic cholinergic nerves, while also inhibiting vagal reflexes, thereby helping to balance the overall function of the autonomic nervous system. Common anticholinergic drugs used in the preanesthesia preparation phase include atropine, scopolamine, anisodamine, and pentoxyverine hydrochloride.

[0003] In particular, atropine is often chosen due to its ability to reduce secretions. However, the use of atropine is not without contraindications. It is explicitly prohibited for patients with glaucoma, benign prostatic hyperplasia, and high fever, and should be carefully considered in special cases such as hyperthyroidism, Sjögren's syndrome, and severe heart disease. In practice, due to potentially insufficient preoperative assessment, from an anesthesiology perspective, atropine is considered "unnecessary," and therefore, many medical institutions have discontinued the routine use of "preoperative injections."

[0004] This change has brought new challenges in practice, especially during surgeries requiring patients to be in a lateral decubitus position, where excessive saliva production becomes particularly prominent. The traditional solution is to place a bib under the patient's pillow to absorb excess saliva, but this doesn't completely solve the problem. When saliva production is excessive, the patient's cheeks may be soaked in saliva, the adhesive tape on the endotracheal tube may lose its stickiness due to saliva, and the patient's saliva may even contaminate the surrounding environment of the operating room. There are certain risks involved, both from an infection control and patient safety perspective.

[0005] In summary, existing technologies have significant shortcomings in handling pre-anesthesia medications and managing saliva during surgery. Utility Model Content

[0006] In view of this, this application provides a fish-mouth saliva drainage pad to solve the problems of sensation control and patient safety caused by excessive saliva secretion during lateral decubitus surgery.

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0028] Secondly, it should be noted that in the description of this application, the terms "upper", "lower", "left", "right", "front", "back", "inner", "outer", etc., which indicate the direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0029] The fish-mouth saliva drainage pad 1 proposed in this application embodiment is particularly suitable for use in lateral decubitus surgery. Figure 1-2 As shown in the figure, this application embodiment provides a fish mouth saliva drainage pad, including a drainage pad 1 and a drainage tube 2, wherein the drainage pad 1 and the drainage tube 2 are connected.

[0030] Specifically, in combination Figure 3 The drainage pad 1 includes a gingival surface 11 and a buccal surface 12, which are disposed opposite to each other and are fitted together around their edges to form a drainage channel (not shown in the figure). After the gingival surface 11 and the buccal surface 12 are fitted together to form a drainage pad 1 with a drainage channel, an opening 13 and an outlet (not shown in the figure) are respectively provided at both ends of the drainage pad 1. The opening 13 and the outlet are also located at both ends of the drainage channel, and the opening 13 is connected to the outlet through the drainage channel.

[0031] In one specific embodiment, the gingival surface 11 has a plurality of drainage openings 14 on its front and both sides, and the drainage openings 14 serve a drainage function; the buccal surface 12 is a closed surface as a whole. Preferably, the drainage openings 14 are evenly arranged along the axial direction of the front and both sides of the gingival surface 11.

[0032] In one specific embodiment, one end of the drainage tube 2 is an inlet (not shown in the figure), and the other end is a connection port 21, which is used to connect to an external negative pressure suction device.

[0033] In one specific implementation, such as Figure 1-2 As shown, the opening 13 of the drainage pad 1 is shaped like a fish mouth. The outlet of the drainage pad 1 is connected to the inlet of the drainage tube 2, and the two are joined together to form a fish tail shape. This shape can better fit the internal structure of the oral cavity, reduce the user's foreign body sensation, and make the patient more comfortable to use; moreover, the fish tail-shaped drainage pad can guide saliva to a specific direction, avoiding the accumulation of saliva under the chin.

[0034] Specifically, such as Figure 3 As shown, the cheek surface 12 has several first ridge-shaped protrusions 15 along its drainage direction on one side within the drainage channel, so that a drainage groove is formed between every two adjacent first ridge-shaped protrusions 15. Preferably, the first surface has three first ridge-shaped protrusions 15, and the three first ridge-shaped protrusions 15 are arranged at equal intervals.

[0035] Specifically, such as Figure 4 As shown, at least one second ridge-shaped protrusion 22 is formed on the inner wall of the drainage tube 2 along its drainage direction, so that drainage grooves are formed on both sides of the second ridge-shaped protrusion 22. Due to the limitation of the diameter of the drainage tube 2, one second ridge-shaped protrusion 22 is preferably provided.

[0036] In one specific embodiment, the purpose of setting the ridge-shaped protrusions inside the drainage pad 1 and the drainage tube 2 is to ensure that the drainage will not be affected when it is folded under pressure, and the drainage can continue.

[0037] In one specific implementation, such as Figure 1-2 As shown, the drainage pad 1 has curved edges on both sides to adapt to the internal structure of the oral cavity and improve user comfort.

[0038] In one specific embodiment, both the drainage pad 1 and the drainage tube 2 are made of food-grade soft silicone. Food-grade soft silicone has high safety performance and is soft and skin-friendly, which can also improve the user's comfort.

[0039] The process of using the fish mouth saliva drainage pad in this embodiment is as follows:

[0040] Before anesthesia induction and intubation, the fish-mouth saliva drainage pad of this embodiment is placed into the healthy cheek (gingival buccal sulcus), with the gingival surface 11 of the drainage pad 1 facing the teeth and the buccal surface 12 of the drainage pad 1 facing the buccal mucosa. This prevents the drainage port 14 from sucking onto the mucosa during negative pressure. After placement, it can be fixed together with the endotracheal tube, or fixed separately or not fixed at all. Before positioning, negative pressure suction can be connected to clean the oral secretions. After releasing the negative pressure connection and positioning, suction can be connected again for continuous drainage.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application 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 application.
