Description

Monitoring device

Technical Field

The embodiment of the utility model provides a relate to smart machine technical field, especially relate to a monitoring devices.

Background

The ankle-brachial index (ABI) is the ratio of the systolic pressure of the ankle artery (usually the posterior tibial artery or the dorsal foot artery) to the systolic pressure of the brachial artery of the upper arm after the patient has rested on his back for 10 minutes. ABI was originally proposed and described by Winsor for the first time for non-invasive detection of arterial disease of the lower extremities. A large number of subsequent studies have shown that ABI can also be used as an indicator for determining the occurrence of cardiovascular events and impaired limb function in PAD patients. The american heart disease society (ACC/AHA) guide indicates: ABI is normal at 1.00-1.40, ABI is critical abnormal state at 0.90-0.99, ABI is less than 0.9, PAD can be diagnosed, and ABI is more than 1.4, which indicates that the artery has poor constriction.

However, the current products for detecting artery disease of lower limb adjust the inflation amount of the cuff wrapped around the ankle of the upper or lower limb to change the pressure to obtain the ankle index, and then determine whether artery disease of lower limb occurs. It can be known that the existing products for detecting artery diseases of lower limbs are large in size and inconvenient to carry, and cannot realize continuous monitoring, so that the aim of early detection cannot be fulfilled.

It is understood that arterial disease of the lower limb can lead to poor blood circulation of the lower limb, which is characterized by a lower temperature of the lower limb and lower temperature of the arm of the upper limb, i.e. the first temperature is lower than the second temperature, and the specific temperature difference (the ratio of the first temperature to the second temperature) is inversely related to the severity of arterial disease of the lower limb. For example, when the target subject does not suffer from a lower limb arterial disease, the ratio of the first temperature to the second temperature is close to 1, and when the target subject suffers from a lower limb arterial disease, the first temperature is lowered due to poor blood circulation of the lower limb, so that the ratio between the first temperature and the second temperature is reduced, and the more serious the lower limb arterial disease is, the smaller the ratio between the first temperature and the second temperature is. Thus, it may be determined whether the target subject has a lower limb arterial disease or not based on a ratio between the first temperature and the second temperature.

For example, when the ratio is less than or equal to a preset ratio threshold, it is determined that the target object has lower limb artery disease, and when the difference is greater than the preset difference threshold, it is determined that the target object does not have lower limb artery disease. It is understood that the preset ratio threshold may be an empirical value, or may be determined by a person skilled in the art according to an experimental result, for example, the temperature ratio and the corresponding systolic pressure ratio of the person without lower limb arterial disease and the person with lower limb arterial disease are collected through a large number of experiments, whether lower limb arterial disease occurs or not can be determined according to the systolic pressure ratio, and then, the corresponding relationship between the temperature ratio and whether lower limb arterial disease occurs or not is determined, so that the preset ratio threshold can be determined.
