A device for detecting atrial fibrillation

Abstract

The invention discloses an atrial fibrillation detection device. The atrial fibrillation detection device comprises a wrist strap, a human body inductor, a pulse inductor, a central processing unit, a power module, a display module, an alarm module, a storage module and a wireless module, wherein the human body inductor, the pulse inductor, the central processing unit, the power module, the display module, the alarm module, the storage module and the wireless module are located inside the wrist strap; the human body inductor is used for inducing the human body; the pulse inductor is used for sensing the pulse of the human body and sending sensed pulse signals to the central processing unit; the central processing unit continuously selects six pulse intervals S<1>-S<6> from the pulse signals, calculates the duration of each pulse interval and judges whether the six pulse intervals S<1>-S<6> meet a first condition and a second condition or not, and if the pulse intervals S<1>-S<6> meet the first condition and the second condition at the same time, the central processing unit sends an alarm signal to the alarm module, and meanwhile drives the display module to display alarm information. The atrial fibrillation detection device overcomes the defect that an existing atrial fibrillation detection technology needs to rely on network analysis, and has the advantages of being easy to operate, high in practicability, capable of achieving noninvasive operation, suitable for everyday detection, convenient to carry and the like.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an atrial fibrillation detection device. Background technique [0002] Atrial fibrillation is a recurrent cardiac arrhythmia. There are about 20,900 male and 12,600 female patients with atrial fibrillation in the world, and about 120,000 to 215,000 new patients with atrial fibrillation are diagnosed every year. The prevalence of tremor is about 3%, and it can reach 10% in people over 75 years old. The frequency of atrial fibrillation is 350-600 beats / min, the atrial contraction is invalid, blood stasis in the atrium is easy to form thrombus, and the thrombus falls off, leading to cerebral embolism, superior mesenteric artery embolism, limb arterial embolism, etc.; patients with non-valvular atrial fibrillation The incidence of stroke is 5.6 times that of normal people, and the incidence of stroke in valvular atrial fibrillation is 17.6 times that of normal people. 20-30% of ischem...

Problems solved by technology

The above-mentioned technologies all rely entirely on the network for ECG detection and diagnosis. Due to the low familiarity and use of the Internet by the elderly group, the application feasibility of the above-mentioned technology for the elderly group has certain limitations.

[0008] To sum up, the existing autonomous detection system for atrial fibrillation mainly relies on the network, a certain fee is charged for each detection, and the operation is relatively complicated, so it is necessary to improve it
