Description

Technical Field

[0001] The invention relates to the technical field of oral spray medicine, and in particular to a spray medicine device for treating oral mucositis. Background Art

[0002] During radiotherapy or chemotherapy, the patient's oral mucosa undergoes an inflammatory reaction. The main symptoms of these reactions include mucosal erythema, erosion, severe oral ulcers and local pain. These symptoms not only affect the patient's eating, swallowing and speaking functions, but may also reduce their quality of life. At the same time, oral mucositis may also be secondary to Candida albicans infection, viral infection, bacterial infection, etc., causing the patient to have systemic symptoms such as fever and fatigue. In severe cases, oral mucositis may even threaten the patient's life.

[0003] In a Chinese patent with publication number CN113967310A, a portable oral treatment sprayer is disclosed, which can adjust the extension length and angle of the spray head by adjusting the adjustment component, so as to adapt to the oral depth of different patients, and can make the spray head point to a specified position, so as to achieve the effect of precise spraying;

[0004] Therefore, for the treatment of oral mucositis in patients undergoing radiotherapy and chemotherapy, a handheld oral care sprayer is used to apply medicine to the affected area. During the use of the handheld oral care sprayer, a pipe is usually inserted into the patient's oral cavity to spray the liquid medicine, thereby achieving the purpose of applying the medicine;

[0005] For patients whose oral inflammation is located deeper inside the oral cavity, after the sprayer sprays the medicine on the affected area in the oral cavity, the patient will feel a foreign body in the mouth, which will cause discomfort when the taste buds on the patient's tongue taste the medicine, causing the patient to swallow instinctively, resulting in a brief closure of the patient's mouth. The medicine can only be sprayed again after the patient's mouth is opened again, which requires multiple adjustments to the sprayer and the spraying position of the oral inflammation area, affecting the convenience of spraying and reducing the device's treatment efficiency for the oral cavity.
