Description

A device for applying liquid medicine and paste medicine in a disposable periodontal pocket

technical field

The invention relates to a dental medical appliance, in particular to a device for applying liquid medicine and paste medicine in a disposable periodontal pocket.

Background technique

Periodontitis is mainly a chronic inflammation of periodontal supporting tissues caused by local factors. The age of onset is more common after the age of 35. If gingivitis is not treated in time, the inflammation can spread from the gums to the deep layer of the periodontal ligament, alveolar bone and cementum and develop into periodontitis.

The early symptoms of periodontitis are not obvious, and patients often only have secondary gingival bleeding or halitosis, which are similar to gingivitis symptoms. During the examination, the gingival margin, gingival papilla, and attached gingiva were swollen and soft, dark red or dark red, and easy to bleed on probing. With the further spread of inflammation, the following symptoms appear: Periodontal pocket formation Due to the expansion of inflammation, the periodontal ligament is destroyed, the alveolar bone is gradually absorbed, the gums and roots are separated, and the gingival sulcus is deepened to form periodontal pockets. The period of periodontal pocket formation is a better time for treatment. If the periodontal pocket wall is not treated in time, there will be ulcers and inflammatory granulation tissue formation, and purulent secretions will remain in the pocket. Bad breath, which eventually leads to tooth loss.

In actual clinical treatment, there are two types of drug application methods for the treatment of periodontitis after periodontal pocket formation:

1. The method of applying liquid medicine is: most doctors use the probe hook in the disposable tray to attach the liquid medicine, and send it in through the air. If it is accidentally dropped, it will cause environmental pollution and waste. Another is to use tweezers to dip and smear around the teeth, and then use a probe to introduce the drug hook around the teeth and the inner wall of the periodontal pocket to achieve the purpose of applying the drug.

2. The method of applying medicine to cream-like gel medicine is: this kind of medicine has a round and flat tip medicine delivery tube with a diameter of about 1 mm, and the medicine is sent to the edge of the periodontal pocket by infusion, and then used The probe is sent into the bag to achieve the purpose of drug application.

Both of these two methods have the existence of slight inadvertence, which will cause the soft tissue in the bag to be pierced by a sharp weapon, causing varying degrees of pain and injury, and the medicine cannot be accurately and comprehensively delivered to the blind environment.

The existing technology is too clinically purposeful, and the application of medicine is too simple, and there is no special tool to meet clinical use.

Therefore, for those skilled in the art, it is necessary to provide a periodontal pocket liquid ointment that can make periodontal medication standardized, accurate, comfortable, comprehensive, and easy to operate, so that the drug can play a sustained release effect and have obvious effects. The drug-feeding device for bar has become an important research topic.
