Expiratory positive pressure nasal/face mask with remote monitoring function

Abstract

The invention discloses an expiratory positive pressure nasal / face mask with remote monitoring function. The expiratory positive pressure nasal mask comprises a face mask body, wherein a gas inlet pipe and a gas outlet pipe are arranged on the face mask body; a pressure sensor and a temperature sensor are arranged on the gas outlet pipe; a hypoglossal nerve stimulation device comprises a first processor, a pulse generator and a hypoglossal nerve electrode. An image acquisition device includes a second processor, a power supply module, a camera and a projector. A cloud server receives data sentby the first processor and image information sent by the second processor, and sends the data and the image information to a remote monitoring terminal. As for the expiratory positive pressure nasal / face mask with remote monitoring function, the pressure sensor and the temperature sensor respectively detect pressure data and temperature data of the exhaled gas in the gas outlet pipe. When there is no pressure data or the temperature data remains unchanged, the first processor sends a pulse signal to the hypoglossal nerve electrode through a pulse transmitter to stimulate the jaw tongue muscle. The image acquisition device collects the image information of the front of the expiratory positive pressure nasal / face mask in real time and monitors the image information remotely.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a positive expiratory pressure nasal mask with remote monitoring function. Background technique [0002] Sleep-disordered breathing is divided into obstructive sleep apnea-hypopnea syndrome (OSAHS), central sleep apnea syndrome (CSA) and mixed sleep apnea (CSAS). Among them, OSAHS is the most common sleep-disordered breathing, which refers to repeated complete or partial obstruction or collapse of the upper airway, resulting in apnea or hypoventilation, repeated hypoxemia, hypercapnia, repeated arousal and sleep A disease characterized by structural disorders and decreased sleep quality. OSAHS can occur at any age, especially middle-aged and elderly people, and the prevalence rate increases with age, but the prevalence rate of OSAHS decreases when the age exceeds 60 or 70 years old. Sleep apnea has a high incidence and great harm. It is the source of chronic medical diseases and ...

Problems solved by technology

OSAHS can occur at any age, especially middle-aged and elderly people, and the prevalence increases with age, but the prevalence of OSAHS decreases when the age exceeds 60 or 70

Sleep apnea has a high incidence and great harm. It is the source of chronic medical diseases and brings heavy social and economic burdens. The current standard treatment of non-invasive ventilation is still expensive, and the compliance is not high. It is ineffective for central apnea, etc. shortcoming

[0003] The main treatment measures for OSAHS are as follows: one is to use surgical operations, oral appliances, positive airway pressure ventilation, and nasal dilators to solve the problem of apnea or hypoventilation. Among them, there are many kinds of oral appliances, which are mainly used in The effectiveness of patients with simple snoring and mild to moderate OSAHS cannot be confirmed; surgical operations often use uvulopalatopharyngoplasty and modified uvulopalatopharyngoplasty with uvula preservation, and are often used in the upper airway oropharynx Obstruction and AHI<20 times / h, but this surgical method can only partially solve the obstruction problem of the upper airway oropharynx, and the total effective rate is <50%

Moreover, the trauma is large, the cost is high, and the postoperative recurrence is easy; the second is to use a ventilator to pump the airflow generated by the air pump into the upper airway through the mask, provide positive pressure to support the upper airway, reduce the resistance of the upper airway, and continue to breathe. Positive tract pressure stimulates the baroreceptors to increase the muscle tension of the upper airway, thereby maintaining the opening of the upper airway. The existing ventilator is expensive, the instrument is large in size, and it is not easy to carry it around. It is easy to promote and use at home. Especially inconvenient, and the connected tubing restricts the patient's nocturnal movement, and constant positive pressure means constant airflow, which causes discomfort for most patients

[0004] To sum up, the existing positive expiratory pressure nasal masks are complex in structure, expensive in price, poor in wearing comfort for users, and do not have remote management functions
