Product description
parameter

Function:
1. Pulse wave velocity (PWV);
2. Ankle brachial blood pressure index (ABI);
characteristic:
1. Pulse wave velocity (PWV)
(1) PWV (pules wave velocity):
PWV calculation formula and clinical criteria:
Pwv= distance / time difference( Δ t)
(2) Clinical significance: arterial system elasticity decline is a comprehensive response of a variety of cardiovascular risk factors to the early damage of vascular wall. It is not only a sign of specificity and sensitivity in the early stage of vascular disease, but also a high-risk factor, which is involved in the occurrence and development of cardiovascular disease. Therefore, the non-invasive detection of arterial system elasticity is becoming a research hotspot. Pulse wave velocity (PWV) measurement is one of the commonly used noninvasive arterial elastic function indicators. As a non-invasive method, PWV can detect the abnormality of arterial function early and comprehensively reflect the damage of various risk factors to blood vessels. PWV increase is an independent risk factor for cardiovascular events, which provides a reliable discriminant index for evaluating the effect of clinical intervention.
(3) Range of normal and abnormal values of PWV:
The value of PWV will increase with age, and its reference value is 1400cm/s.
According to the American College of Cardiology medical / scientific report (1993):
a. Pwv<1400cm/s: normal arteriosclerosis.
b. 1400cm/s<=pwv<=1800cm/s: mild peripheral arterial sclerosis.
2. Ankle brachial blood pressure index (ABI)
Clinical significance: ABI can evaluate the opening of lower limb arteries and vessels without trauma, and predict the occurrence and death of various cardiovascular and cerebrovascular events. It is more accurate and objective than using PWV alone to measure arteriosclerosis. This is because, if the artery is highly narrow or occluded, the pulse wave is blocked at the occluded site, so it has to pass through the collateral branch, so the propagation of the pulse wave will slow down. At this time, PWV sometimes shows normal value or low value regardless of the progress of arteriosclerosis, which is easy to mislead the disease diagnosis. The ABI will decrease significantly. From the value of ABI, we can find that the arteries of the lower limbs are occluded. Therefore, ABI index can be used as a complement to PWV to predict arteriosclerosis more comprehensively.
Normal abnormal value: under normal conditions, ABI ≥ 1. If ABI < 1, it often indicates that there is stenosis and occlusive disease in the arteries of the lower limbs; If ABI < 0.5, it indicates severe ischemia of lower limbs. If possible, lower limb blood supply should be reconstructed in time.
(3) Normal range of ABI: 0.9~1.4
ABI value
Possible lesions
ABI<0.9
Peripheral arteries of lower limbs are at risk of hardening or narrowing, peripheral vascular disease (PAD)
ABI<0.8
Peripheral arteries of lower limbs are at great risk of hardening or narrowing, peripheral vascular disease (PAD)
zero point five
A part of peripheral arteries of lower limbs may have been completely blocked, peripheral vascular disease (PAD)
ABI<0.5
Peripheral arteries of lower limbs may have been completely blocked in several places, peripheral vascular disease (PAD)
ABI>1.3
Calcification of lower extremity vessels

Equipment for detecting arterial stiffness and arterial occlusion. It can provide clinical data for early detection and treatment of major diseases such as cardio cerebrovascular disease and diabetes. It is a comprehensive screening and prognosis evaluation device.
1. Registered name: Arteriosclerosis detection system
*2. Function: no trauma detection.
a. Three segments of pulse wave conduction velocity PWV (neck thigh: aorta, neck circumference: upper limb artery, thigh foot: lower limb artery,) can be detected at the same time;
b. Ankle brachial index.
*3. Pulse wave detection method: the pulse wave conduction velocity PWV is measured independently and directly, and the piezoelectric sensor pulse wave synchronous detection method is adopted;
*4. Measure the neck, thigh, circumference and foot, and truly obtain the pulse wave conduction velocity PWV of three segments (neck thigh: aorta, neck circumference: upper limb artery, thigh foot: lower limb artery,) to ensure its accuracy;
*5. ABI ankle brachial index: simultaneous measurement of limb blood pressure, which can simultaneously measure the arteries of upper and lower limbs. The ankle brachial index (ABI) and the pressure difference between arms were obtained;
6. High fidelity contact force sensor is adopted, and the pulse wave acquisition signal is accurate, objective and stable.
7. Functional requirements: it is applicable to the early diagnosis of arteriosclerosis, early screening of cardiovascular disease and diabetes complications, and providing basis for the prognosis evaluation of prevention and treatment effects, which can be used for scientific research.
8. Test indicators: PWV (three-stage), ABI
*9. Channel: 4-channel pulse wave detection, which can display the pulse waveform of 4 parts.
10. Limb blood pressure measurement: can measure the left and right ABI values
11. Test report: full Chinese operation interface (including the patient's name), color graphic report, and guiding proposal.
