Description

Technical Field

[0001] This utility model relates to the mounting bracket for oral sprayers, specifically to a metered sprayer for oral mucosal protectants. Background Technology

[0002] Oral mucosal protectant sprays are devices used to protect and repair the oral mucosa. They are commonly used to alleviate oral infections and other problems in patients with granulomatosis after chemotherapy. They spray a liquid containing protective ingredients into the mouth to help repair damaged oral mucosa, reduce pain and discomfort, and promote healing.

[0003] Most existing oral mucosal protectant sprayers use a needle-like structure to spray the oral mucosal protectant onto the affected area in the patient's mouth. However, in actual use, the volume of oral mucosal protectant sprayed varies depending on the different treatment needs of each patient. Too much or too little oral mucosal protectant can affect the effectiveness of the treatment. Furthermore, when dealing with patients who have difficulty opening their mouths, the large needle-like structure is difficult to insert into their mouths, and the spray angle of the needle-like structure is also relatively fixed. Patients with difficulty opening their mouths have a smaller mouth opening angle, which results in a smaller range of needle insertion into the mouth. Consequently, the needle-like structure cannot provide precise spraying treatment to the affected areas in the mouths of patients with difficulty opening their mouths.

[0004] Therefore, to address the problems of existing oral sprayers in terms of the difficulty in dispensing a measured amount of protective agent and the inflexibility of adjusting the spray nozzle position, a metered-dose oral mucosal protectant sprayer has been developed. By adding a metered-dose spraying structure and a nozzle angle adjustment structure to the existing oral sprayer, the oral sprayer can dispense a measured amount of oral mucosal protectant to the affected area of ​​the mouth according to the treatment needs of different patients, and the spray nozzle position can be flexibly adjusted to better suit patients with difficulty opening their mouths.

Then, press the second roller 25 with your hand to maintain the fixed angle of the spray nozzle 7 after adjustment.

[0036] Then, press the hand-press button 17 to push the threaded rod 6 and piston 15 downwards, so that the piston 15 delivers the oral mucosal protectant in the pen core 5 to the spray nozzle 7 through air pressure, and then the spray nozzle 7 sprays the oral mucosal protectant to the patient's oral cavity.

[0037] Through the above steps, the first roller 16 is turned to drive the threaded rod 6 and piston 15 to rotate and rise. The height of the piston 15 is adjusted according to the digital scale on the first roller 16. This controls the amount of oral mucosal protectant sprayed from the refill 5 by the piston 15 each time the user presses the hand-press button 17, thus achieving a quantitative spraying effect with each press. Furthermore, the second roller 25 can be turned to drive the extension bracket 24 to rotate and adjust the spray nozzle composed of the spray nozzle 7 and the feeding needle 23, making it suitable for oral treatment of patients with difficulty opening their mouths. The antibacterial silver ion layer on the outer wall of the spray nozzle 7 can prevent accidental contamination of the spray nozzle 7, thereby improving the antibacterial and hygienic properties of the spray nozzle 7. This solves the problems of existing oral sprayers that make it difficult to quantitatively spray the protectant and that the spray position of the nozzle is difficult to adjust flexibly.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments.
