An electronic sphygmomanometer with atrial fibrillation detection function

Abstract

The invention discloses an electronic sphygmomanometer with an atrial fibrillation detection function. The electronic sphygmomanometer comprises a collection module, a judgment module, a grouping module, a computation module and a comparison module, wherein the collection module collects a pulse signal sequence and extracts and records pulse time intervals; the judgment module judges whether the quantity of the recorded pulse time intervals is twice or more than twice a preset quantity; the grouping module groups a former preset quantity of the pulse time intervals and a latter preset quantity of the pulse time intervals which are sequenced from small to big into two groups; the computation module is used to compute deviation values between the two groups of pulse time intervals; and the comparison module is used to compare each pulse time interval deviation value with a preset threshold so as to determine whether the values exceed the threshold and thus determine whether arrhythmia exists. The electronic sphygmomanometer disclosed by the embodiment of the invention has the advantages that a function of atrial fibrillation detection is set on common home-use electronic equipment with a pulse signal collection function; a user's expenditures can be reduced; and functionality, practicability and a utilization rate of the electronic equipment can be increased.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an electronic sphygmomanometer with atrial fibrillation detection function. Background technique [0002] Atrial fibrillation, referred to as atrial fibrillation, is one of the most common arrhythmias, and the incidence of atrial fibrillation increases with age. In atrial fibrillation, the heartbeat frequency is not only much faster than the normal heartbeat, but also absolutely irregular, and the atrium loses effective contraction function. Atrial fibrillation is prone to complications such as cerebral infarction, thromboembolism, cardiac insufficiency, and sudden cardiac death, among which 20% of stroke events are related to atrial fibrillation. AF increases the risk of arterial thromboembolism and ischemic stroke fivefold. Therefore, if atrial fibrillation is detected and treated in time, the incidence of complications can be greatly reduced. [0003] At present, the diagn...

Problems solved by technology

Although this detection method is convenient, it cannot be used for long-term monitoring of PPG (photoplethysmography) signals because the smartphone also supports other functions, and the misjudgment rate of atrial fibrillation detection is high, which is of significance for the initial screening of potential patients with atrial fibrillation not big

In addition, it is not practical or economical to design a product specifically for atrial fibrillation detection to increase the possible detection rate of atrial fibrillation, because from the perspective of users, a new device needs to be purchased; from the perspective of equipment, the function single, low utilization
