Description
Technical Field
The present disclosure relates to an olfactory training device based on expiratory pressure.
Background
Normal olfaction function is indispensable for maintaining daily behaviors of human beings, and plays an important role in social interaction, danger early warning, physical and mental health assurance and the like. The population of patients with neurodegenerative diseases such as Alzheimer's disease, parkinson's disease and the like is huge, and researches show that the olfaction decline is an early warning signal of cognitive dysfunction of the patients with neurodegenerative diseases, and the risk that the elderly with olfaction disorder develops dementia in the next 5 years is 2 times that of the elderly without olfaction disorder. Furthermore, most studies indicate that senile dysosmia is closely related to high mortality.
Recent research results show that olfactory training can significantly improve olfactory and cognitive functions of patients with common types of olfactory disorders, including senile, traumatic, post-upper-body, inflammatory and other olfactory disorders, and the current evidence of olfactory training is of IA grade. Imaging studies have shown that the effectiveness of olfactory training is related to the increased olfactory response of the olfactory mucosal epithelium and the change in structure of olfactory processing areas of the brain. In addition, the optimization of olfactory training can enhance its effects, such as increasing the variety of olfactory training odors, extending the duration of olfactory training, combining glucocorticoid nasal irrigation, etc. For patients with dysosmia due to nasal cavity and paranasal sinus anatomy or mucosa swelling, such as nasal septum deflection, chronic sinusitis and the like, the airflow entering the nasal cavity olfactory cleavage area is limited, so that the diffusion and deposition of olfactory element in the olfactory cleavage area are limited, and the effectiveness of olfactory training is further reduced.
At present, no device for olfactory training exists in the domestic market, the olfactory training device produced by Burghart company internationally is in a cylinder shape, olfactory hormone smell is emitted automatically, a patient performs olfactory training through sniffing, and for olfactory disorder patients with nasal cavity airflow limitation, the diffusion and deposition of olfactory hormone molecules in the nasal cavity are limited, so that the olfactory training effect is reduced.
