Description
Technical Field
[0001] The utility model relates to the technical field of injection devices, in particular to an infusion device used in a tympanic cavity. Background Art
[0002] Tympanic injection is a common local drug delivery method in otology, which means delivering drugs into the middle ear and diffusing them into the inner ear through the round window membrane or oval window to achieve therapeutic or diagnostic effects. In recent years, tympanic injection technology has been increasingly used in the clinical application of otology diseases, mainly including the diagnosis and treatment of sudden deafness, Meniere's disease, secretory otitis media and autoimmune inner ear diseases.
[0003] Traditional tympanic injection therapy mostly requires puncturing the tympanic membrane with a fine needle with the assistance of an otoscope, and then injecting the corresponding drug into the tympanic cavity. However, this method still has some defects, such as a long course of treatment and the need for multiple punctures and drug administration. A course of traditional tympanic injection generally involves 3 or more drug injections, and each injection will cause a certain degree of pain and fear to the patient. In addition, traditional tympanic injection is generally performed with the assistance of an otoscope, requiring the doctor to be proficient in otoscope operation, and has a certain technical threshold. The above problems will force patients to seek treatment in large hospitals when undergoing this treatment. For patients in some areas with inconvenient transportation or underdeveloped medical conditions, the time cost and medical cost are high. Therefore, there is an urgent need for an infusion device that is simple and convenient to operate and can reduce pain and fear during the injection process to solve the above problems. Utility Model Content
[0004] In order to solve the problems arising from the above-mentioned background technology, the purpose of the present utility model is to provide an infusion device for the tympanic cavity, which includes an injection kit, a connector, an infusion tube, and a clamp. The external end of the infusion tube is connected to the injection kit, and the internal end is connected to the clamp. The clamp cooperates with the fixing part so that it can be stably clamped in the tympanic membrane position. The clamp cooperates with the injection kit to inject the drug into the tympanic cavity from the external auditory canal opening, so as to reduce the pain and fear brought to the patient by multiple punctures of the tympanic membrane in the traditional method, improve the patient's medical experience, and the whole process can be completed under direct vision of the naked eye, without the assistance of an otoscope, and can be completed in a general small hospital, which reduces the operating threshold of the technology and the time cost and medical cost required for patients to seek medical treatment.
