Description

Technical Field

[0001] The utility model relates to the field of oral irrigation devices, in particular to a self-controlled oral irrigation device. Background Art

[0002] Oral cancer is a common head and neck malignancy, not only severely damaging oral function but also posing a significant threat to patients' lives. Among the adverse reactions associated with radiotherapy in oral cancer patients, oral mucositis accounts for as high as 85%, with severe cases accounting for 31%. This significantly impacts patient comfort and quality of life, and can even be a significant factor in discontinuing treatment for a small number of patients.

[0003] In the field of oral care, existing oral irrigator technologies cover multiple aspects such as high-pressure water flow, pulse, intelligence and ultrasound. For oral cancer patients, these technologies are not convenient for patients to control themselves, and may aggravate pain or affect wound healing. They cannot meet the special needs of oral cancer patients and reduce patient compliance. Currently, there is no dedicated oral irrigator for this purpose in clinical practice. In view of this, we propose a self-controlled oral irrigator. Utility Model Content

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-Figure 5 As shown, a self-controlled oral irrigator includes a liquid storage tank 1, a liquid supply hole 6 connected to the inner cavity of the liquid storage tank 1 is provided on the lower side of the outer surface of the liquid storage tank 1, a placement rack 2 is fixedly mounted on the side of the top of the liquid storage tank 1 away from the axis, a shower mechanism 3 is inserted into the placement rack 2, a hose 4 is fixedly mounted between the input end of the shower mechanism 3 and the output end of the liquid supply hole 6, a pressurizing mechanism 7 is provided in the inner cavity of the liquid storage tank 1, and an opening and closing assembly 8 is provided on the shower mechanism 3;

[0024] When this solution is actually used, first remove the shower mechanism 3 from the placement rack 2, hold the shower mechanism 3 with one hand and aim it at the oral lesion, start the booster mechanism 7, and the booster mechanism 7 pressurizes the inner cavity of the liquid storage tank 1, so that the medicine liquid in the inner cavity of the liquid storage tank 1 is output to the shower mechanism 3 through the hose 4 for spraying. During this period, the user can press the opening and closing component 8 on the shower mechanism 3, so as to control the flow rate of the shower mechanism 3 when spraying the medicine liquid, so as to avoid the medicine liquid from impacting the wound surface too quickly, aggravating the pain or affecting the healing of the wound, and other adverse phenomena.

[0025] Specifically, the boosting mechanism 7 includes a mounting shell 71 and a cylinder 75. The mounting shell 71 is fixedly mounted at the middle of the top end of the inner cavity of the liquid storage tank 1. A tube 72 is fixedly mounted at the axis of the bottom end of the mounting shell 71. The tube 72 is connected to the inner cavity of the mounting shell 71. Four air inlet grooves 711 are formed in an annular array on the top wall of the inner cavity of the mounting shell 71.

[0026] An electric cylinder 73 is fixedly mounted on the inner surface of the mounting shell 71. The output shaft of the mounting shell 71 extends into the inner cavity of the tube body 72 and is fixedly connected to a telescopic rod 74 at one end via a coupling. A piston 741 is fixedly mounted at the bottom end of the telescopic rod 74, which slides within the inner cavity of the tube body 72. Two one-way valves 742 are installed on both sides of the piston 741 away from the middle.

[0027] The electric cylinder 73 is started, and the output shaft of the electric cylinder 73 drives the telescopic rod 74 to slide up and down. During this period, the telescopic rod 74 drives the piston 741 at its bottom end to reciprocate along the inner surface of the tube body 72. In this way, as the piston 741 reciprocates in the inner cavity of the tube body 72, the gas in the tube body 72 is pressed into the inner cavity of the liquid storage tank 1. As the air pressure in the inner cavity of the liquid storage tank 1 increases, the liquid in the liquid storage tank 1 is introduced into the shower mechanism 3 through the liquid supply hole 6 along the hose 4 for spraying;

[0028] External air flows into the inner cavity of the mounting shell 71 and the tube body 72 respectively through the four air inlet grooves 711. When the piston 741 moves upward, the air in the upper part of the inner cavity of the tube body 72 flows back into the lower part of the inner cavity of the tube body 72 through the two one-way valves 742.

[0029] Furthermore, the cylinder 75 is fixedly mounted at the axis of the bottom wall of the inner cavity of the liquid storage tank 1, and a spring 751 is vertically fixedly mounted in the inner cavity of the cylinder 75. A penetrating sliding hole 771 is opened in the middle of the inner cavity bottom wall of the tube body 72, and four air inlet holes 77 are opened in a circular array on four sides of the inner cavity bottom wall of the tube body 72 away from its axis. A sliding rod 761 is slidably mounted on the inner surface of the sliding hole 771, and a limit block 762 is fixedly mounted on the top end of the sliding rod 761. A butt piece 76 is fixedly mounted on the bottom end of the sliding rod 761, and the top end of the spring 751 is abutted against the bottom end of the butt piece 76.

[0030] When the piston 741 compresses the air in the inner cavity of the tube body 72 downward, the tube body 72 pushes the limit block 762 downward to drive the slide rod 1 761 to slide vertically downward along the slide hole 1 771, so that the stop piece 1 76 at the lower end of the slide rod 1 761 is separated from the bottom end of the tube body 72, so that the top end of the stop piece 1 76 no longer blocks the four penetrating air inlet holes 77 at the lower end of the tube body 72. In this way, the high-pressure gas generated by the compression of the piston 741 enters the inner cavity of the liquid storage tank 1 through the four air inlet holes 77 for pressurization;

[0031] When the high-pressure gas enters the inner cavity of the liquid storage tank 1, as the piston 741 releases the pressure on the limit block 762 upward, the tension of the spring 1 751 in the inner cavity of the cylinder 75 pushes the retaining plate 1 76 upward to reset it. In this way, the retaining plate 1 76 re-blocks the four air inlet holes 77 to prevent the liquid in the liquid storage tank 1 from flowing back into the inner cavity of the tube body 72.

[0032] Specifically, the shower mechanism 3 includes a shower head 31. A shower hole 2 34 is provided at the middle of the top of the shower head 31 and is connected to the inner cavity thereof. A plurality of shower holes 1 33 are provided at the front end of the shower head 31 at equal intervals. A handle tube 32 is fixedly mounted at the bottom end of the shower head 31 and is connected to the inner cavity thereof.

[0033] When the booster mechanism 7 is in operation, the liquid medicine flows into the handle tube body 32 through the hose 4 and is sprayed outward through the second shower hole 34 or the multiple first shower holes 33 on the spray head 31. When the liquid medicine is sprayed outward through multiple first shower holes 33, its flow rate will decrease, and when the liquid medicine flows outward through a single second shower hole 34, its flow rate will also increase. The opening and closing of the first shower hole 33 and the second shower hole 34 are controlled by providing an opening and closing component 8.

[0034] Furthermore, the opening and closing assembly 8 includes a second sliding hole 82, which is provided in the middle of the rear end of the sprinkler head 31. A second sliding rod 86 is slidably mounted on the inner surface of the second sliding hole 82. A pressing handle 83 is fixedly mounted on the top end of the second sliding rod 86, and a second stopper 81 is fixedly mounted on the bottom end of the second sliding rod 86.

[0035] The top of the second abutment 81 is provided with a blocking block 85 adapted to the second shower hole 34. Four second springs 84 are fixedly installed at the four corners of the bottom end of the inner cavity of the spray head 31. The tops of the four second springs 84 are respectively abutted against the bottom end of the second abutment 81.

[0036] The pressing handle 83 is pressed downward to make the sliding rod 86 push the second piece 81 downward in the vertical direction along the sliding hole 82 to block the front of the multiple shower holes 33. During this period, the blocking block 85 at the front end of the second piece 81 moves downward together with the second piece 81, thereby releasing the degree of blocking the second shower hole 34. In this way, the medicine can only be sprayed outward through a single shower hole 34. On the contrary, the pressing handle 83 is released, and the tension of the four springs 84 at the bottom of the inner cavity of the sprinkler head 31 pushes the second piece 81 upward. In this way, the blocking block 85 blocks the second shower hole 34 again, and the second piece 81 also loses its blockage of the multiple shower holes 33, so that the medicine can flow out from the multiple shower holes 33.

[0037] It should be noted that the specific installation method, circuit connection method and control method of the electric cylinder 73 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
