Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a device capable of continuously attracting saliva. Background Art

[0002] Patients with swallowing disorders, such as the elderly, stroke patients, and even patients with severe brain damage, are unable to swallow independently when bedridden. Excessive saliva flows out of the mouth and down the cheeks, causing the cheeks to remain moist for a long time, which can easily cause skin diseases such as eczema. The inability to swallow saliva independently can also easily cause coughing and choking, or even suffocation, endangering the patient's life. In hospitals, saliva is mainly attracted by suction equipment. The suction end of the suction tube needs to be fixed on the inside of the patient's cheek, and the other end is connected to a negative pressure tube. Since the suction port on the wall of the suction tube is in direct contact with the oral mucosa, continuous suction will cause damage to the patient's oral mucosa. Therefore, it is necessary to design a device that can continuously attract saliva and is not prone to causing damage to the patient's oral mucosa. Utility Model Content

[0023] A specific embodiment, as shown in the figure, is a preferred embodiment of the present invention. A device for continuously absorbing saliva mainly comprises a connecting piece, a first water absorbing part, and two second water absorbing parts. An air suction pipe and an air inflation pipe are provided in the connecting piece. The air suction pipes are interconnected inside the connecting piece. The air suction pipe is provided with a pipe opening on each side of the connecting piece. The first pipe opening of the air suction pipe is connected to the negative pressure suction structure. The second pipe opening of the air suction pipe is provided on the side opposite to the first pipe opening. The second pipe opening is connected to the first water absorbing part. The third pipe opening and the fourth pipe opening of the air suction pipe are respectively connected to a second water absorbing part. The first end of the air inflation pipe is connected to the external air inflation structure 3 through the first air inlet pipe 4. The first air inlet pipe 4 is provided with a valve. The first end of the air inflation pipe and the first pipe opening of the air suction pipe are located on the same side of the connecting piece. The second end of the air inflation pipe is connected to the first water absorbing part through the second air inlet pipe 8.

[0024] The first water-absorbing component includes a first suction pipe 10, a first cotton sleeve 9, and an air bag 14. The first suction pipe 10 is a Y-shaped tube. The first end of the first suction pipe 10 is connected to the second pipe opening of the suction pipe, the second end of the first suction pipe 10 is installed on the upper surface of the air bag 14, and the third end of the first suction pipe 10 is installed on the lower surface of the air bag 14. A plurality of suction holes are provided on the second and third ends of the first suction pipe 10. The air bag 14 is connected to the second end of the inflation pipe through the second air inlet pipe 8; the air bag 14 is wrapped in the first cotton sleeve 9, the interior of the first cotton sleeve 9 is an inner cavity, the upper surface of the air bag 14 is in contact with the top surface of the inner cavity, the lower surface of the air bag 14 is in contact with the bottom surface of the inner cavity, and the first end of the first suction pipe 10 extends out of the first cotton sleeve 9;

[0025] The second water-absorbing component includes a second suction pipe 12 and a second cotton sleeve 11. The first end of the second suction pipe 12 is provided with a plurality of suction holes. The first end of the second suction pipe 12 is sleeved with the second cotton sleeve 11. The second ends of the second suction pipes 12 of the two second water-absorbing components are respectively connected to the third pipe opening and the fourth pipe opening of the suction pipe of the connecting component.

[0026] The first cotton sleeve 9 and the second cotton sleeve 11 of the present invention are used to absorb saliva in the oral cavity. For hygiene reasons, the first and second water-absorbing components are disposable and need to be replaced regularly. They can be discarded after use. The finished first and second water-absorbing components are packaged in separate packaging bags. When in use, the packaging bags are opened. The connector of the present invention can be used multiple times by the same patient in a short period of time. After use, it needs to be disinfected to facilitate the next use, which can reduce resource waste and reduce treatment costs. When in use, the packaging bag is opened and the first and second water-absorbing components are connected to the connector. First, the first pipe opening of the suction pipe is connected to the negative pressure suction structure, the second pipe opening of the suction pipe is connected to the first end of the first suction pipe 10 of the first water-absorbing component, and the third and fourth pipe openings of the suction pipe are respectively connected to the second suction pipes 12 of the two second water-absorbing components. Then, the first end of the inflation pipe is connected to the inflation structure 3 through the first air inlet pipe 4, and the air bag 14 of the first water-absorbing component is connected to the second end of the inflation pipe of the connector. After the connection is completed, the two second cotton sleeves 11 are placed on the inside of the patient's cheeks on both sides to absorb the saliva produced on the inside of the cheeks. At the same time, the first cotton sleeve 9 wrapped with the airbag 14 is placed in the patient's mouth and placed on the tongue surface. The valve on the first air inlet pipe 4 is opened, and air is inflated into the airbag 14 connected to the inflation pipe of the connector through the inflation structure 3, so that the airbag 14 expands and props up the first cotton sleeve 9, so that the first cotton sleeve 9 fits against the patient's tongue surface and palate, thereby absorbing the saliva produced on the tongue surface and palate through the first cotton sleeve 9. There are many types of inflation structures 3, all of which are existing technologies and will not be described in detail here. When the airbag 14 is inflated, it also acts as a limiter for the first cotton sleeve 9. Furthermore, the second air intake pipe 8 is connected to the airbag 14, and the first suction pipe 10 is connected to the first cotton sleeve 9. Furthermore, because the second air intake pipe 8 and the first suction pipe 10 are connected to the connector, the top and bottom surfaces of the connector are both provided with an inwardly concave bite portion 6. The cross-sectional shape of the connector is I-shaped, and the bite portion 6 divides the connector into a front end 5 and a rear end 7. The front end 5 refers to the end located outside the oral cavity. The third and fourth pipe openings of the suction duct are located on two side surfaces of the front end 5 of the connector. When the patient bites the bite portion 6 of the connector, the position of the connector cannot be moved at will, so that the second air intake pipe 8 and the first suction pipe 10, which are fixed in length and connected to the connector, will not move toward the throat, so that the first cotton sleeve 9 connected to the first suction pipe 10 can be fixed in the patient's oral cavity and will not move toward the patient's throat. The suction and inflation tubes are mounted within the connector. When a patient bites on the connector, the connector prevents them from biting, preventing them from being bitten, thus preventing the use of the first and second absorbent components. Furthermore, the first and second absorbent components are integrally connected to the connector, allowing for easy insertion and removal of the first and second absorbent components into and out of the oral cavity by simply lifting the connector.After installation and placement, the negative pressure suction structure is used to continuously absorb saliva through the first suction tube 10 and the second suction tube 12 connected to the suction pipe of the connector. Under the action of the first cotton sleeve 9 and the second cotton sleeve 11, the first suction tube 10 and the second suction tube 12 will not directly contact the patient's oral mucosa. Therefore, continuous suction is not likely to damage the patient's oral mucosa.

[0027] Furthermore, a flat suction shell 13 is provided at the second and third ends of the first suction tube 10. A plurality of suction holes are formed on the surface of the suction shell 13, and the suction shell 13 is in contact with the inner surface of the first cotton sleeve 9. The flat shape of the suction shell 13 can increase the contact area with the first cotton sleeve 9, thereby improving the suction effect when negative pressure suction is performed.

[0028] Furthermore, the first suction tube 10, the second suction tube 12 and the second air inlet pipe 8 are all soft tubes, which facilitates the placement of the first water absorbing component and the second water absorbing component in the oral cavity, and can be moved to a suitable position when placed.

[0029] Furthermore, a soft pad is provided on the surface of the occlusal portion 6 to act as a buffer and protect the patient's teeth.

[0030] Furthermore, two side surfaces of the front end 5 of the connector are connected with fixing belts, and the connector is fixed to the patient's head through the fixing belts to prevent the connector from falling off the patient's mouth.

[0031] Furthermore, the outer surfaces of the first cotton cover 9 and the second cotton cover 11 have a smooth transition, which improves the comfort of use and is not likely to damage the inside of the patient's mouth.

[0032] Furthermore, the first nozzle of the suction duct is connected to the saliva collection bottle 1 via a collection tube 2, which is in communication with the negative pressure suction structure via the suction tube. A one-way valve is installed in the collection tube 2. The opening direction of the one-way valve is from the connector toward the collection bottle 1, collecting saliva in the collection bottle 1 for subsequent processing. The one-way valve installed in the collection tube 2 can also prevent saliva from flowing back.

[0033] The above description is a detailed description of the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
