Description

Nasal cavity hemostasis device

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a nasal cavity hemostasis device and an operation method thereof.

Background

When the skull base is fractured by external force, shock is easily caused, a large amount of oral and nasal bleeding is often accompanied, and the bleeding also easily enters the trachea to cause aspiration, so that serious consequences are caused. The nasal cavity bleeding can be effectively controlled in time, the nasal cavity or the retronasal hole can be filled for hemostasis, and the prevention of aspiration is an effective clinical treatment measure. Due to the anatomical particularity of the nasal sinuses, the irregular structure of the nasal cavity and the great difference of the sizes of the individual nasal sinuses of the patient, the filling material of the nasal cavity and the nose is required to have plasticity; meanwhile, the nasopharynx air passage needs to be effectively blocked. The existing hemostatic materials and hemostatic devices do not meet the above requirements.

Chinese patent No. CN212729892U discloses a nasal cavity hemostasis device, which comprises a catheter, a balloon connected to the end of the catheter, and an expansion hemostasis material covering the periphery of the catheter. When the nasal cavity hemostat is used, the saccule and the catheter are plugged into the nasal cavity, the saccule is plugged into the position of the posterior nostril, and liquid/air is filled into the saccule through the catheter to expand the saccule so as to stanch the posterior nostril. Meanwhile, the expansion hemostatic material is also positioned in the nasal cavity, and if the anterior nasal cavity bleeds, the expansion hemostatic material absorbs blood to expand, so that the anterior nasal cavity can be stopped. After hemostasis is finished, liquid/gas is extracted from the saccule through the catheter, the saccule is contracted, and the size is reduced during extraction, so that secondary damage to the wound surface is avoided. However, this hemostatic device has a complicated structure, easily damages the mucous membrane during use, and is poor in comfort to the human body.
