Description

Multi-balloon imbedded nasopharynx filling device Technical Field The invention relates to the technical field of medical appliances, in particular to a multi-balloon imbedded nasopharynx filling device. Background Nasopharyngeal hemorrhage is an emergency common in otorhinolaryngology, and quick, effective and safe hemostasis by stuffing is a key link of treatment. Currently, the nasopharynx filling device widely used clinically mainly comprises vaseline sliver, expansion sponge, single-balloon or double-balloon filling device and the like, however, the devices have obvious defects in practical application, and multiple requirements of accurate hemostasis, comfort level of patients and maintenance of basic ventilation are difficult to be considered. Traditional vaseline sliver filling needs medical personnel to manually fill the nasopharynx cavity layer by layer, and complex operation and consuming time are longer, easily lead to local too high pressure because of the dynamics of filling unevenly, cause patient's severe pain, nasal mucosa secondary damage, even lead to hemostasis failure or bleeding recurrence because of filling inadequately. Meanwhile, the gauze strip is filled to completely block the nasal cavity ventilation channel, so that a patient is forced to rely on oral breathing for a long time, complications such as dry mouth, pharyngalgia, dyspnea and the like are easy to induce, and the hospitalization experience and treatment compliance are obviously reduced. The existing balloon-type filling devices, such as single balloon or double balloon filling devices, although partially solving the problem of operation convenience, still have the common problem of insufficient ventilation. The nasal cavity hemostatic device is mainly of a single or double balloon structure, the air sac is fixed in shape, and cannot adapt to the anatomical characteristics of large individual difference and irregular cavity channels of the nasal cavity, such as the bony structural variation of the nasal cavity, mucosa folds and the like, so that the air sac and the nasal cavity wall are insufficient in fit, compression blind areas are easy to form, and uniform compression hemostasis is difficult to realize. In addition, the balloons of such devices typically completely occlude the nasal passages after filling, and patient breathing is still impeded. In addition, although some devices have the function of regulating the pressure of the air bags, the devices lack the independent and accurate regulation capability of each air bag, the compression strength can not be regulated for specific bleeding parts, and the defects of tissue ischemia necrosis caused by overhigh local pressure or incomplete hemostasis caused by insufficient compression still exist. Materials such as expansion sponge also have similar problems, and after expansion, the airway is blocked as well, and secondary damage may be caused by adhesion when taken out. Disclosure of Invention The invention mainly aims to provide a multi-balloon imbedded nasopharynx filling device which aims at adapting to irregular nasopharynx cavity forms, providing multi-point independent pressure regulation and control to realize uniform compression hemostasis and guaranteeing smooth nasal ventilation. To achieve the above object, the present invention provides a multi-balloon insertion type nasopharynx filling device comprising: The filling body comprises a flexible outer layer and a supporting catheter, the supporting catheter extends along the axial direction, and the flexible outer layer is wrapped outside the supporting catheter; The air bag units extend towards one end of the filling body, and a plurality of air bag units are arranged between the flexible outer layer and the supporting catheter and are distributed along the circumferential direction; The inflation assembly is arranged at one end of the packing body and communicated with the inflation port, and each air bag unit can be inflated independently by the inflation assembly; And a breathing channel is arranged on the filling body, and penetrates through the flexible outer layer and the supporting catheter. In some embodiments of the invention, the inflation assembly includes a rotary inflation member and an indexing positioning mechanism; The rotary inflating piece comprises an inflating pipe and a rotary inflating ring, the rotary inflating ring is provided with a hollow inflating cavity, one end of the inflating pipe is connected with an external air source, and the other end of the inflating pipe is communicated with the inflating cavity; the rotary inflating ring is movably sleeved on the supporting guide pipe and can rotate relative to the supporting guide pipe; A through hole for being in butt joint with the inflation port is formed in one side, facing the inflation port, of the rotary inflation ring; the indexing positioning mechanism is arranged between the rotary inflating ring and the supporting guide pip
