Abstract

The invention relates to the field of medical devices, in particular to a multifunctional device for continuously supplying nasal cavity wounds, which consists of a catheter part, an inflatable part and a drug supply part, and the drug supply part includes: a drug injection valve (9), an injection valve Drug tube (6) and drug storage balloon (4). The drug storage balloon (4) is located outside the inflatable balloon (3) in the middle of the nasal catheter (2), and the two are in a nested relationship, the inner surface is the inflatable balloon (3), and the outer surface is the drug storage balloon (4) . The drug storage balloon is made of microporous silica gel film. The invention is mainly used in the repair of nasal passage wounds after nasal cavity surgery, in addition to pressurized hemostasis, fluid drainage, nasal passage cleaning and nasal ventilation, as well as preventing patient nasal cavity healing deviation, nasal septum deviation and postoperative cerebrospinal fluid rhinorrhea, etc. In addition to functions such as complications, the more important thing is that through the drug supply part, hemostatic drugs, painkillers and anti-inflammatory and anti-infective drugs can be continuously used locally on the wound to speed up wound healing and reduce patient pain.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a multifunctional device for continuously supplying nasal cavity wounds. Background technique [0002] The following symptoms usually appear after nasal cavity surgery: bleeding, pain and swelling. In severe cases, secondary infection may occur, which brings great pain to the patient. For hemostasis, traditional methods are usually used: oil gauze stuffing or self-made water bag, air bag compression to stop bleeding, and spraying drugs after cauterization. These methods have a certain hemostatic effect, but they also bring a variety of discomforts to patients, such as: headache, dry mouth, nasal congestion, swelling of the face, and even difficulty in eating or breathing in severe cases. In the prior art, there is also a method of using a straight tube ventilation hemostatic airbag, but it will cause the patient's nasal cavity to heal deviation, nasal septum deviation, and serious...
