Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely endoscopic endonasal surgery, and can be used to visualize a surgical field during endoscopic endonasal surgery in patients with polypous rhinosinusitis. During the operation in case of bleeding and reduced visualization of the surgical site at least 8 on the Wormald scale, a wedge-palatal artery and/or its branches are coagulated ipsilateral to the side with increased haemorrhage. For this purpose, the mucoperiost is separately separated under the control of the endoscope after the posterior wall of the maxillary sinus is visualized by the raspinator in the projection of the ascending process of the palatine bone towards the anterior wall of the sphenoid sinus. What is found is a wedge-and-palate opening and a wedge-palatal artery/branches of the wedge-palatine artery exiting/leaving it and performing its/their coagulation. After achieving haemostasis, the visualization level of the surgical field is evaluated. When visualization is improved, the separated muckoperiost is laid back and endoscopic endonasal polysynusotomy is continued. 
     EFFECT: method enables achieving clinically significant improvement of surgical field visualization during endoscopic endonasal surgery in patients with polypous rhinosinusitis, does not increase operative injuries as a whole by preserving vascularization of mucous membrane by branches of mesenteric arteries and facial artery.

Abstract: FIELD: fire safety; vehicles. 
     SUBSTANCE: group of inventions relates to a method for fire protection of a vehicle and a device for its implementation. Method is intended to prevent ignition of moving vehicle with external arrangement of fuel tanks during ignition of energy carrier. Method is implemented by throwing off a burning fuel tank by means of a device which contains a tank holder in the form of a frame space L-shaped structure. Holder is hinged to car frame frame hinge and locked in working position by lock mechanism. Fuel tank is arranged and fixed in the holder cavity. Tilting mechanism of the holder comprises: a pushing tank panel, a pusher, a traction cable and a consumable panel. Expendable fabric is made in the form of strip of flexible fabric or mesh width, larger width of wheel of car, and with load on lower end face is placed in box-container. Container is placed in front of wheel in direction of car movement from below under holder and fixed with cover by means of electromagnetic lock. Device switch is placed in the cabin and connected to the vehicle on-board network. For the fire fuel tank to be thrown off by the electromagnetic valve, the power supply system is switched to the non-burning tank if necessary and the device is switched on. Electromagnetic lock opens the box-container cover, it opens, the load falls on the road, pulling the consuming cloth behind it. Vehicle wheel rides on web and pulls it. Stretching force in the web is transmitted via traction cable and pusher to pushed panel and fuel tank causing their transverse motion. Fuel tank is disconnected, the holder is opened. It is turned or tilted about the longitudinal axis until the posts stay in the base limiters. Under action of gravity tank is accelerated and discarded. Fuel pipes from fuel lines and electric wire from fuel level sensor are broken. Expendable cloth in attachment of upper end is detached from traction cable. Vehicle passes along the consuming panel and continues further movement.
