Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a negative pressure device for clearing oral secretions. Background Technology
[0002] An artificial airway is a passage established through the mouth, nose, or trachea to ensure airway patency, assist ventilation, or clear secretions. Common forms include endotracheal intubation and tracheotomy. This technique is widely used in critical care, general anesthesia, and for patients requiring long-term respiratory support.
[0003] Because artificial airways bypass the natural anatomical structures of the upper respiratory tract, they significantly impair a patient's swallowing function. The presence of an endotracheal tube or cannula restricts larynx elevation, reduces pharyngeal sensation, hinders glottal closure, and affects the normal shielding function of the epiglottis, leading to a significant decrease in swallowing coordination. Clinically, patients often experience difficulty swallowing oral secretions, which easily leak towards the airway or drool from the corners of the mouth. This not only increases the risk of aspiration and aspiration pneumonia but also causes moist and eroded perioral skin due to persistent drooling, increasing the risk of infection and severely affecting patient comfort.
[0004] Therefore, how to design a negative pressure oral secretion removal device that can effectively collect oral secretions and prevent them from flowing into the airway or out of the corners of the mouth is a technical problem that has not yet been solved in the existing technology. Utility Model Content
[0005] Therefore, the technical problem to be solved by this utility model is to overcome the technical defects of the prior art, which make oral secretions difficult to swallow, easy to flow into the airway or flow out from the corner of the mouth, which not only increases the risk of aspiration and pneumonia, but also causes the skin around the mouth to be moist and eroded, causing infection and seriously affecting the patient's comfort. Thus, a negative pressure oral secretion removal device that can effectively collect oral secretions and prevent them from flowing into the airway or flowing out from the corner of the mouth is provided.
[0006] Therefore, this utility model provides a negative pressure oral secretion removal device, comprising: The mouth suction head is suitable for being held in the oral cavity. One end facing the depth of the oral cavity forms an outwardly convex arc-shaped surface. At least one first suction hole is provided on the outwardly convex arc-shaped surface. The position of the first suction hole avoids the protrusions of the outwardly convex arc-shaped surface. A silicone soft sleeve is fitted onto the mouthpiece suction head, and a second suction hole is provided opposite to the first suction hole. Several unconnected first convex arc strips are formed on the outer side wall around the second suction hole. The negative pressure tube is connected at one end to the oral suction head and then to the first suction hole, and at the other end is adapted to connect to the suction bucket.
[0007] As a preferred embodiment, a shaping hose is also included, which is sleeved and installed on the end of the negative pressure tube near the mouthpiece, for adjusting the angle of the mouthpiece.
[0008] As a preferred embodiment, the shaping tube is provided with a plastic shaping filament inside, which can be plastically deformed to adjust the bending angle of the shaping tube, thereby adjusting the orientation of the mouthpiece.
[0009] As a preferred embodiment, a second convex arc strip is formed on the outer side wall of the silicone sleeve at the protrusion position of the convex arc surface.
[0010] As a preferred embodiment, there are four first suction holes, with two holes respectively opened along the axial direction on both sides of the protrusion on the outwardly convex arc-shaped surface; The number of the second suction holes corresponds to the number of the first suction holes.
[0011] As a preferred embodiment, the oral suction head includes a suction head and a connector that is inserted and mounted on the suction head. A connecting tube is formed on the outer wall of the connector, and the connecting tube can be fixedly connected to one end of the negative pressure tube. The first suction hole is formed on the suction head.
[0012] As a preferred embodiment, the end of the suction head away from the first suction hole is formed with a receiving protrusion; the end of the connector away from the connecting tube is formed with an insertion protrusion, the insertion protrusion being able to insert into the interior of the receiving protrusion and fit tightly against the inner wall of the receiving protrusion, thereby connecting and installing the suction head and the connector together.
[0013] As a preferred embodiment, the other end of the negative pressure tube is formed with a connecting joint, which is suitable for connecting the negative pressure tube to the suction container.
[0014] As a preferred embodiment, the free end of the connector is formed with several anti-slip flanges.
[0015] As a preferred embodiment, the connecting joint is provided with a negative pressure through hole; It also includes a sealing plug that can be plugged into the negative pressure through hole to seal or open the negative pressure through hole.
[0016] The technical solution provided by this utility model has the following advantages: This utility model discloses a negative pressure suction device for oral secretions, comprising an oral suction head, a silicone sleeve, and a negative pressure tube. The oral suction head is suitable for being placed in the oral cavity, with one end facing the depth of the oral cavity forming a convex arc-shaped surface. At least one first suction hole is provided on the convex arc-shaped surface, and the position of the first suction hole avoids the protrusions of the convex arc-shaped surface. The silicone sleeve is fitted onto the oral suction head and has a second suction hole opposite to the first suction hole. Several unconnected first convex arc strips are formed on the outer side wall around the second suction hole. One end of the negative pressure tube is connected to the oral suction head and then communicates with the first suction hole, while the other end is suitable for connecting to a suction container.
[0017] When used on patients with an artificial airway, first connect the other end of the negative pressure tube to the suction container, then connect the suction container to the negative pressure device and adjust the negative pressure to a suitable intensity. After adjustment, instruct the patient to hold the suction head in their mouth. Under negative pressure, oral secretions are suctioned out through the first suction hole and flow into the suction container. This oral secretion negative pressure removal device features a silicone soft sleeve with a certain weight, allowing the suction head to sink to the bottom of the oral cavity for effective suction of secretions. Its outer wall has a first convex arc strip that contacts the oral mucosa, thus preventing the first suction hole from directly adhering to the oral mucosa and causing mucosal damage. Compared to traditional suction catheters that require manual operation and are prone to damaging the oral mucosa, this oral secretion negative pressure removal device effectively prevents adsorption trauma to the oropharyngeal tissues and eliminates the need for continuous hand-held operation by medical personnel. The patient only needs to hold the suction head in their mouth for continuous and safe secretion removal. Attached Figure Description

[0029] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example
[0030] This embodiment provides a negative pressure device for clearing oral secretions, such as... Figure 1-3 As shown, it includes: an oral suction head 1, a silicone soft sleeve 5, and a negative pressure tube 3; wherein, the oral suction head 1 is adapted to be held in the oral cavity, and one end facing the depth of the oral cavity forms an outwardly convex arc-shaped surface 2, and at least one first suction hole 21 is opened on the outwardly convex arc-shaped surface 2, the opening position of the first suction hole 21 is set to avoid the protrusion 22 of the outwardly convex arc-shaped surface 2; the silicone soft sleeve 5 is sleeved and installed on the oral suction head 1, and has a second suction hole 51 opposite to the first suction hole 21, and a plurality of unconnected first outwardly convex arc strips 53 are formed on the outer side wall around the second suction hole 51; one end of the negative pressure tube 3 is connected to the oral suction head 1 and then communicates with the first suction hole 21, and the other end is adapted to be connected to a suction container.
[0031] When used on patients with an artificial airway, first connect the other end of the negative pressure tube 3 to the suction container, then connect the suction container to the negative pressure device and adjust the negative pressure to a suitable intensity. After adjustment, instruct the patient to hold the suction head 1 in their mouth. Under negative pressure, oral secretions are suctioned out through the first suction hole 21 and flow into the suction container. In this embodiment, the oral secretion negative pressure removal device has a silicone soft sleeve 5 with a certain weight, which allows the suction head 1 to sink to the bottom of the oral cavity to effectively attract secretions. The first outwardly convex arc strip 53 on its outer wall contacts the oral mucosa, thereby preventing the first suction hole 21 from directly adhering to the oral mucosa and causing mucosal damage. Compared with traditional suction tubes that require manual operation and are prone to damaging the oral mucosa, the oral secretion negative pressure removal device of this embodiment can effectively prevent adsorption trauma to the oropharyngeal tissues and does not require continuous hand operation by medical staff. The patient only needs to hold the suction head 1 in their mouth to achieve continuous and safe secretion removal.
[0032] It also includes a shaping tube 4, which is sleeved and installed at the end of the negative pressure tube 3 near the mouth suction head 1, and is used to adjust the angle of the mouth suction head 1. When the patient is in a lateral decubitus position, oral secretions may accumulate in the buccal area. At this time, by adjusting the angle of the shaping tube 4, the suction hole of the mouth suction head 1 can be aligned with the side where the secretions accumulate, thereby achieving effective suction. The shaping tube 4 allows for flexible adjustment of the suction direction according to the patient's position, enhancing the effect of clearing oral secretions.
[0033] like Figure 4 As shown, the shaping hose 4 is provided with a plastic shaping filament 41 inside. The plastic shaping filament 41 can be plastically deformed to adjust the bending angle of the shaping hose 4, thereby adjusting the orientation of the mouth suction head 1.
[0034] On the outer wall of the silicone soft sleeve 5, a second convex arc strip 52 is formed at the protrusion 22 position on the convex arc surface 2. This protrusion is the most prominent part on the convex arc surface 2. The second convex arc strip 52 provided at this position can further enhance the protective effect, effectively prevent the suction hole from directly contacting the oral mucosa, thereby reducing the risk of mucosal tissue damage.
[0035] There are four first suction holes 21, with two holes on each side of the protrusion 22 on the outwardly convex arc-shaped surface 2 along the axial direction; the number of second suction holes 51 corresponds to the number of first suction holes 21. Multiple first suction holes 21 can improve the suction efficiency of oral secretions, enhance the suction effect, and thus more effectively remove accumulated fluid.
[0036] like Figure 5-6 As shown, the oral suction head 1 includes a suction head 11 and a connector 12 inserted and installed on the suction head 11. A connecting tube 13 is formed on the outer wall of the connector 12, and the connecting tube 13 can be fixedly connected to one end of the negative pressure tube 3; the first suction hole 21 is opened on the suction head 11.
[0037] The end of the suction head 11 away from the first suction hole 21 is formed with a receiving protrusion 14; the end of the connector 11 away from the connecting tube 13 is formed with an insertion protrusion 15. The insertion protrusion 15 can be inserted into the interior of the receiving protrusion 14 and fit tightly against the inner wall of the receiving protrusion 14, thereby connecting and installing the suction head 11 and the connector 12 together.
[0038] The other end of the negative pressure tube 3 is formed with a connecting joint 31, which is suitable for connecting the negative pressure tube 3 to the suction bucket.
[0039] The free end of the connector 31 is formed with several anti-slip flanges 34. The anti-slip flanges 34 can enhance the connection stability between the connector 31 and the suction container, prevent the operation from being interrupted due to loosening or falling off during use, and thus ensure the continuity and stability of the suction process.
[0040] The connecting joint 31 is provided with a negative pressure through hole 32; it also includes a sealing plug 33, which can be plugged into the negative pressure through hole 32 to seal or open the negative pressure through hole 32. When performing secretion suction, inserting the sealing plug 33 into the negative pressure through hole 32 can create a negative pressure in the negative pressure tube 3, thereby starting the suction operation; when it is necessary to stop suction, pulling out the sealing plug 33 will release the negative pressure and stop the suction.
[0041] The oral secretion negative pressure removal device in this embodiment is used as follows: When used on a patient with an artificial airway, first connect the other end of the negative pressure tube 3 to the suction container, then connect the suction container to the negative pressure device, and adjust the negative pressure to a suitable intensity; after adjustment, instruct the patient to hold the suction head 1 in their mouth, insert the sealing plug 33 into the negative pressure through hole 32 to create negative pressure in the negative pressure tube 3, and the oral secretions are suctioned out through the first suction hole 21 and flow into the suction container; when suction needs to be stopped, pull out the sealing plug 33 to release the negative pressure and stop suction; when the patient is in a lateral decubitus position, adjust the angle of the shaping tube 4 so that the suction hole of the suction head 1 is aligned with the side where secretions accumulate, thereby achieving effective suction.
[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
