[0037] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] like Figure 1 to Figure 4 As shown, a spray-suction oral care sputum suction device according to a preferred embodiment of the present invention comprises: a sputum suction tube 1;

[0039] A housing 2, to which the sputum suction tube 1 is connected;

[0040] The collecting part 3 includes a sputum suction cup 31, a collecting inlet pipe 32 and a collecting outlet pipe 33. The sputum suction cup 31 is detachably connected to the housing 2. The sputum suction pipe 1 is connected to one end of the housing 2. One end of the collecting inlet pipe 32 is penetrated by the sputum suction pipe 1 and the housing 2 and connected to the sputum suction cup 31. One end of the collecting outlet pipe 33 is connected to the sputum suction cup 31, and the other end is used to connect to a negative pressure source.

[0041] The medicine spraying part 4 includes a medicine storage tank 41, a medicine spraying inlet pipe 42 and a medicine spraying outlet pipe 43. One end of the medicine spraying inlet pipe 42 is penetrated by a sputum suction pipe 1 and extends to the shell 2 to be connected to the medicine storage tank 41. One end of the medicine spraying outlet pipe 43 is connected to the medicine storage tank 41, and the other end is used to connect to an air pressure source; and

[0042] The camera unit 5 is connected to one end of the housing 2 connected to the sputum suction tube 1 and can take a picture of the sputum suction tube 1 .

[0043] The working process of the present invention is as follows: before operation, the medical staff observes the patient's oral cavity in real time through the sputum suction tube 1 of the camera part 5 to accurately locate the sputum or infected area; then the spraying part 4 is started, and the spraying outlet pipe 43 sprays the liquid in the medicine storage tank 41 through the spraying outlet pipe 43 through the air pressure source, so that the liquid medicine softens the sputum and exerts an antibacterial effect; simultaneously, the secretions are quickly removed through negative pressure suction, and the sputum is sucked into the collection inlet tube 32 and the sputum suction tank 31 in turn through the negative pressure source.

[0044] Based on the above scheme, by using the camera unit 5 to take real-time images of the inside of the oral cavity, medical staff can intuitively locate the sputum accumulation area and the oral lesion site, reducing the risk of mucosal damage caused by traditional blind operations. The coordinated design of the spray unit 4, the collection unit 3 and the suction tube 1 supports "rinsing and suctioning at the same time". The medicine storage tank 41 uses the air pressure source to accurately deliver the drug cleaning solution or antibacterial solution to the lesion, soften the sputum and inhibit bacterial reproduction. The negative pressure source instantly absorbs the flushing solution and secretions through the collection tank to avoid choking and aspiration. The detachable collection tank and medicine storage tank 41 support rapid replacement and disinfection, reducing the risk of cross-infection. The spraying, suction, and camera functions are integrated into the handheld device, and there is no need to frequently switch tools during operation. Nurses can operate alone and reduce work fatigue.

[0045] Further preferably, the camera unit 5 also includes a camera and a fill light, which can provide uniform illumination, present a high-contrast image even in the dark area of ​​the oral cavity, and ensure accurate positioning. The integration of the camera and the fill light not only supports multi-angle observation, but also reduces the operation blind spot, shortens the suction time and reduces the risk of aspiration.

[0046] Furthermore, the spray-suction oral care sputum suction device also includes a toothbrush 6, which is detachably connected to the end of the sputum suction tube 1 away from the shell 2, and the toothbrush 6 is hollow, and the toothbrush 6 and the sputum suction tube 1 are connected to each other.

[0047] Based on the above scheme, the toothbrush 6 is connected to the end of the suction tube 1 and can be quickly disassembled to adapt to different care scenarios. The toothbrush 6 is hollow and internally connected to the suction tube 1 structure. The spray outlet 43 is injected with physiological saline or liquid medicine through the medicine storage tank 41 to rinse the oral cavity; the suction tank 31 is connected to a negative pressure device to simultaneously suck away secretions and rinsing liquid.

[0048] Furthermore, the collection inlet pipe 32 and the spray inlet pipe 42 are sequentially accommodated in the toothbrush 6, the sputum suction tube 1 and the shell 2.

[0049] Based on the above scheme, the collection inlet pipe 32 and the spray medicine inlet pipe 42 successively penetrate the hollow cavity of the toothbrush 6, the interior of the suction tube 1 and the shell 2, forming a continuous and closed two-way fluid transmission path. The spray medicine inlet pipe 42 extends from the medicine storage tank 41 of the shell 2 to the front nozzle of the toothbrush 6, and the collection inlet pipe 32 is connected back from the suction port of the toothbrush 6 to the suction tank 31 of the shell 2 to avoid the risk of entanglement or contamination caused by the exposure of the pipeline. The double tubes adopt a coaxial nested design or parallel arrangement to adapt to the narrow diameter of the toothbrush 6 and the suction tube 1, ensuring that the injection of liquid medicine and the suction of secretions do not interfere with each other.

[0050] Furthermore, the toothbrush 6 is also fixedly connected to a transmission rod 7 and includes a rotating part 8, which includes a knob 81, a connecting rod 82, a first gear 83 and a second gear 84; the connecting rod 82 is passed through the shell 2, and one end of the connecting rod 82 away from the shell 2 is fixedly connected to the knob 81, and the other end of the connecting rod 82 is fixedly connected to the first gear 83, and the transmission rod 7 is fixedly connected to the second gear 84, and the second gear 84 and the first gear 83 are meshed with each other.

[0051] Based on the above scheme, the toothbrush 6 is fixedly connected to the second gear 84 through the transmission rod 7, and the first gear 83 inside the shell 2, that is, the connecting rod 82 and the knob 81 are linked to form a meshing transmission system. When the knob 81 outside the shell 2 is rotated, the connecting rod 82 drives the first gear 83 to rotate, and then drives the second gear 84 and the transmission rod 7 to achieve a 180° controllable rotation of the toothbrush 6 head. Medical staff can adjust the rotation angle and speed of the toothbrush 6 head through the knob 81, and perform directional brushing on dead corners such as teeth and tongue coating. During the rotational cleaning process, the collection inlet tube 32 continuously suctions negative pressure, and simultaneously removes softened sputum and flushing fluid, realizing a synchronous closed loop of brushing-flushing-attraction.

[0052] Furthermore, the rotating part 8 also includes an abutment plate 85 , through which the transmission rod 7 , the collection inlet pipe 32 and the spray inlet pipe 42 are arranged, and the transmission rod 7 and the abutment plate 85 are fixedly connected.

[0053] Based on the above solution, the abutment plate 85 is fixed inside the housing 2, serving as a common support base for the transmission rod 7, the collection inlet pipe 32, and the spray inlet pipe 42. The transmission rod 7 is rigidly connected to the abutment plate 85 to ensure the axial stability of power transmission during gear transmission, and to avoid the deviation or distortion of the pipeline caused by the eccentric force generated by the rotation of the brush head.

[0054] Furthermore, the shell 2 includes a handle 21 and a mounting portion 22 . The handle 21 and the mounting portion 22 are hollow and interconnected. The sputum suction tube 1 is connected to one end of the mounting portion 22 away from the handle 21 .

[0055] Based on the above solution, the housing 2 is composed of a handle 21 and a mounting portion 22, both of which are hollow and internally connected, allowing the flushing liquid, secretions and negative pressure airflow to be seamlessly transmitted in the housing 2 to form a closed circulation path. The handle 21 adopts an ergonomic arc design, and the surface is covered with a non-slip texture, which is suitable for operators with different hand shapes to hold for a long time. Its internal hollow structure reduces the overall weight and reduces the hand fatigue of medical staff.

[0056] Furthermore, the collecting part 3 also includes a power supply 34 and a fan 35. The power supply 34 is connected to the inside of the handle 21. The power supply 34 and the fan 35 are electrically connected. The fan 35 is connected to the mounting part 22 and can provide a negative pressure source for the end of the collecting tube 33 away from the suction cup 31.

[0057] Based on the above solution, the fan 35 is fixed inside the mounting portion 22 and connected to the collecting outlet pipe 33 through a closed air duct, and the negative pressure intensity can be dynamically adjusted to provide a stable negative pressure source for the far end of the suction tube 1.

[0058] Furthermore, a button 23 is provided on the outer periphery of the housing 2 , and the button 23 is electrically connected to the fan 35 and the power supply 34 .

[0059] Based on the above solution, the operation is intuitive, and the layout of the buttons 23 reduces the training cost and improves the nursing efficiency. The buttons 23 can control the switch of the fan 35, thereby controlling the collection part 3 to collect sputum.

[0060] Furthermore, the spray part 4 also includes an airbag 44 and a pressing piece 45. The pressing piece 45 is slidably connected to the handle 21. The airbag 44 is connected to the end of the spray outlet tube 43 away from the suction cup 31. The pressing piece 45 can press the gas in the airbag 44 to provide an air pressure source for the end of the spray outlet tube 43 away from the suction cup 31.

[0061] Based on the above scheme, the pressing member 45 squeezes the airbag 44, and the gas is transported to the medicine storage tank 41 through the spray medicine inlet pipe 42, and then the air pressure drives the liquid medicine to be sprayed out from the spray medicine outlet pipe 43. The medical staff can complete the pressing action by naturally extending their thumb, realizing the synchronous one-hand operation of spraying and suction.

[0062] Furthermore, the spraying unit 4 further includes a fixing frame 46 , which is fixedly connected to the inside of the handle 21 , and the airbag 44 is connected to the inside of the fixing frame 46 .

[0063] Based on the above solution, the fixing frame 46 provides a reliable support foundation for the airbag 44 by being rigidly connected to the inside of the handle 21, thereby avoiding displacement of the airbag 44 due to pressing during the air pressure driving process, thereby ensuring the stability of the medicine spraying unit 4.

[0064] In summary, the embodiment of the present invention provides a spray-suction oral care sputum suction device, which uses the camera unit 5 to capture real-time images of the inside of the oral cavity, so that medical staff can intuitively locate sputum accumulation areas and oral lesions, reducing the risk of mucosal damage caused by traditional blind operations. The coordinated design of the spray unit 4, the collection unit 3 and the sputum suction tube 1 supports "rinsing and suctioning at the same time". The medicine storage tank 41 accurately delivers the drug cleaning solution or antibacterial solution to the lesion through the air pressure source, softens the sputum and inhibits bacterial reproduction. The negative pressure source instantly absorbs the flushing solution and secretions through the collection tank to avoid choking and aspiration. The detachable collection tank and the medicine storage tank 41 support quick replacement and disinfection, reducing the risk of cross infection. The spraying, suction, and camera functions are integrated into the handheld device, and there is no need to frequently switch tools during operation. Nurses can operate alone and reduce work fatigue.

[0065] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
