Publication number: 20170172592Abstract: A nasal balloon catheter and sponge unit is provided for stopping posterior epistaxis (nosebleed) in a quick and adjustable manner. The unit can be easily introduced into the bleeding nasal passage of a patient by a health care provider. Once inserted in the patient's nasal passage, the unit operates through inflation of a posterior balloon via a catheter, acting to stop the posterior bleed. In some embodiments, a second (anterior) balloon covers the inside of the nasal passage and is inflated subsequent to the inflation of the posterior balloon. Excess blood coming out of the nasal passage in the front is stopped by an absorbable sponge. If the packing is loose and blood escapes from the back of the nasal passage, a nut is utilized to squeeze the catheter against the nostril, hence more tightly pulling the posterior balloon to stop the blood.Type: ApplicationFiled: September 23, 2015Publication date: June 22, 2017Inventor: Tanveer Ahmed Janjua
