Micro Screw Pump to Discharge Effusion from Human Middle Ear
نویسنده
چکیده
In this paper we report the development of a micro screw pump for discharging effusion from middle ear for treatment of otitis media. This tool extrudes effusion using a newly designed screw, which rotates at 90,000 rpm in a pipe penetrated through tympanic membrane. This tool satisfies the discharge performance especially for high viscosity effusion while it has smaller diameter such as about 0.5 mm. We also performed clinical application to prove its feasibility usage.

Abstract OME is a Common disease in children. over than 90% of children in preschool ages experienced this disease once at least. Despite medical therapy about 10% of the OME patients won't improved and these are the group of patients who referred to as chronic OME patients. Insertion of VT in TM is an accepted therapy for these patients and during surgery for insertion of VT, suctioning of mi...

Otitis media with effusion (OME) is one of the most common causes of hearing loss (HL) in children. It has been reported that several factors such as eustachian tube dysfunction, insufficiencies in the aeration of the mastoid cells, allergies, immunity, and infections play an important role in the etiology of the disease. Little is known about the role of Helicobacter pylori (H. pylori) in extr...

BACKGROUND Middle ear effusion (MEE) is rare among adults, but has a higher incidence among ICU patients. The aim of this study was to analyze the effect of nasogastric tube (NGT) on MEE and to assess other predisposing factors. METHODS Prospective observational study, carrying out an otoscopic examination and tympanometry in 100 mechanically ventilated patients. Immittance testing was carrie...
