What we want to evaluate today is the vtion health self detector, which is a real health intelligent device because it has only one function - measuring physiological signs such as blood pressure/blood oxygen/heart rate/body temperature.
In tall terms, it is essentially a photoelectric detector, which can calculate the blood pressure, blood oxygen, heart rate and other signs by continuously recording the light transmittance of strong light after penetrating finger tissue and the periodic changes of human bioelectricity.
For patients with hypertension and arrhythmia, this kind of intelligent device should be just needed, but can its use experience attract healthy people to buy it? With this question, let's take a look at its actual performance.
appearance
Users who have played with 3G network cards may remember that vtion is actually a network device, so when looking at its healthy devices, they always feel strange. What is more refreshing is that this self detector has two customized versions, Mobile and Unicom, and this test is the Unicom version.
As a Bluetooth device, the accessories of the machine are quite simple. In addition to the manual and warranty card, it is a data cable for charging.
The machine is in the shape of white pebbles, divided into upper and lower "two lobes", and its bottom edge is surrounded by a ring of chrome plating decoration. The left side of the logo is the mirco USB charging port.
On the right side of the machine is a complete arc transition.
At the bottom of the machine is a rectangular stainless steel patch. During detection, the machine clamps the left index finger, and the right hand needs to touch the patch (possibly for bioelectrical balance correction?).
The strip under the logo of the machine body is actually a work indicator light. Below the indicator light is a round power on button.
The lens like part on the top of the machine is actually an infrared temperature transmitter.
The machine structure is similar to the medical pulse oxygen detector (that is, the instrument clamped on the finger in the hospital), and can be opened like a clamp.
After the machine is spread out, fingers can be "clipped" into it.
Open the mouth of the machine, you can see that there is a LED on the inside of its "upper jaw", which is used to send out "detection light".
The lower jaw of the machine also has a square stainless steel plate, and there is a translucent light receiver behind the stainless steel.
use
The core function of the self inspection instrument is actually to detect four kinds of data, namely "blood oxygen, heart rate, body temperature, blood pressure and ECG". Around health, several small functions such as "exercise and fitness, color vision, intelligence, astigmatism, disease self inspection" are added.
The machine needs to be used with an Android app called "Palm Self Test" (iOS is not supported for the time being). Although the icons and shapes of the application are somewhat low, the functional experience is quite convenient.
After entering the detection interface and selecting an account, the application will prompt the user to turn on Bluetooth, press and hold the power button of the detector for 5 seconds, and they will complete automatic pairing.
Blood oxygen and heart rate
Before measuring, the application will display and play the measurement instructions in pictures, texts and voice.
The real-time reading of the machine will be directly displayed in the mobile phone interface as a waveform, and the report will be automatically generated in about tens of seconds. The detailed blood oxygen and heart rate data can be obtained by simply clamping your finger, which is quite touching.
temperature
The temperature measurement is the fastest and easiest. Just point the infrared transmitter on the back of the detector at the eyebrow and click the power switch to get the real-time temperature data.
It will also display the temperature values under different health conditions in the form of a ruler, and give health advice. This temperature measurement function is also applicable to all kinds of objects that can reflect infrared ray, such as mobile phones and desktops (except transparent objects such as glass).
blood pressure
Because the machine measures blood pressure through the principle of light induction, it can only measure the change value of blood pressure, and the user needs to input the individual systolic and diastolic blood pressure values in advance.
It can also provide health scale and health advice after testing. But users want It is not scientific to know and record the normal diastolic pressure in advance, which directly leads to the low availability and reliability of blood pressure data.
heart rate
Because the heart rate detection result cannot be displayed with a ruler, the heart rate monitoring report will only tell the user whether there is any abnormality.
Health Report
The application will curve the blood oxygen, heart rate, body temperature, blood pressure, ECG and other data measured by the user, and synchronize them to the cloud, so that the user can grasp the trend of changes in physical signs. In order to take care of the majority of users who cannot understand the physical parameters, the data points that exceed the standard will be marked in different colors.
In fact, even if I can't understand the meaning of these figures, I still feel a sense of achievement just by looking at these ups and downs. In addition, it is worth mentioning that although there are not many people who can read the manual, many reference ranges of physical sign values are attached to the thick manual.
As for color vision, intelligence, astigmatism, self-help assessment and other small functions, in fact, ordinary questionnaire tests have nothing to do with machine functions. Function and practicability are better than nothing.
summary
Because of the photoelectric detection, there should be no strong light in the use environment, and naturally there should be no colored nails. However, the connection and measurement process between the machine and the mobile phone are relatively smooth, and the experience is relatively good. The 90 day standby time is also relatively pleasant.
The measurement error of its official calibration is below 2%. Although the evaluation room does not have medical equipment to verify it, the accuracy requirements of civil equipment are not as high as they should be. It is considered to have completed the task if it can record the change trend of relevant values.
However, it still makes a problem that intelligent devices often make, that is, the price is set extremely high, and Xbao is priced at Shenghui 799... Looking at the price, no matter how good the use experience is, it can only be greeted with a whoop.
Well, black can't be too black. In fact, this price is acceptable for chronic patients who often need to measure their physical signs.
