Description

A local sealing treatment device for oral mucosal diseases

Technical Field

The invention relates to the technical field of oral treatment equipment, and in particular to a local sealing treatment device for oral mucosal diseases.

Background Art

Oral mucosal diseases refer to a wide variety of diseases that occur in the oral mucosa and soft tissues. The clinical manifestations are varied. Local blockade with glucocorticoids is a commonly used treatment for a variety of oral mucosal diseases, such as periglandular ulcers, erosive lichen planus, pemphigus vulgaris, mucosal pemphigoid, and submucosal fibrosis. By directly injecting glucocorticoid preparations into the base of oral mucosal lesions, the strong anti-inflammatory, anti-allergic, and submucosal collagen degradation effects of glucocorticoid drugs can be fully exerted to achieve the purpose of rapid healing of lesions and improvement of clinical symptoms. Compared with systemic medication, this method has fewer side effects, higher local drug concentrations, and more accurate and effective treatment. Commonly used glucocorticoid preparations for blockade therapy include triamcinolone acetonide acetate injection, betamethasone sodium phosphate injection, dexamethasone sodium phosphate injection, etc. Among them, triamcinolone acetonide acetate injection is the most commonly used. The drug is a fine-structured suspension that is artificially mixed with saline or 2% lidocaine hydrochloride injection and then injected into the lesion.

At present, 5ml disposable sterile syringes are mostly used clinically for local blockade treatment. However, there are some problems in the clinical use of this therapy: 1. The needle of the conventional 5ml syringe is relatively thick (inner diameter 0.5mm), which can easily cause pain, nausea and other discomfort to the patient when piercing the oral mucosa. In addition, the syringe cannot accurately inject into all parts. Taking gingival lesions as an example, due to the high tension of gingival tissue, the 5ml syringe can only be injected into the vestibule groove adjacent to the gingival lesion, while the disposable syringe is difficult to operate for lesions in the back of the mouth such as the soft palate and the root of the tongue; 2. The traditional method is prone to drug particle deposition at the injection site due to the uneven mixing of artificial drugs and the difficulty in accurately controlling the injection speed and injection volume, which affects the appearance; 3. In order to reduce patient discomfort and achieve the purpose of precise blockade, a 1ml disposable syringe with a relatively small needle is sometimes used. For cases where the lesions are limited and the amount of medication is small, it can basically meet clinical needs, but for cases where the lesions are large or scattered, the amount of medication loaded in the 1ml syringe is limited, and multiple syringes need to be replaced and the medication needs to be prepared multiple times, which increases the difficulty of clinical application and the waste of medication. Therefore, there is an urgent need for accurate, comfortable and controllable local closure treatment devices in clinical practice.
