Electronic blood pressure monitor

In this article I talk about a Electronic blood pressure monitor, acquired on AliExpress, Shop Happy Family Necessities Shop.

Motivation and choice of Model

I already had a blood pressure monitor, also from China, those more compact, to make the measurement wrist. But some time he began to fail in time to inflate the air bag, as if the batteries were weak, even with new batteries. These failures were becoming more constant. With non-rechargeable batteries, working with a slightly higher voltage (1,5In) He even works, but I don't like the idea of stay depending on non-rechargeable batteries, that last bit and whose nominal voltage drops rapidly with the use.

So, It was time to search for a new Electronic blood pressure monitor. This model I bought apparently is the most popular in AliExpress. He has a separate air, that is placed on the arm, like most models used by doctors and clinics.

The Electronic blood pressure monitor can be powered by 4 AAA batteries or by a USB cable, accompanying. But, the device entry specifies 6V, instead of the 5V USB standard. But Interestingly the accompanying power supply has an output of 5V and 1A.

In addition to the cable and the, the Electronic blood pressure monitor also comes with instructions and a bag to keep it.

Unboxing and Tests

When the Electronic blood pressure monitor arrived, did the unboxing and his test, making a video and some pictures. Check out:

Unfortunately this Electronic blood pressure monitor came with problems. Every test he showed values well above normal. I got high blood pressure values, 14/9, having never had high blood pressure. To ensure I tested in my wife and also appeared high values, out of the ordinary.

Another problem is that the Electronic blood pressure monitor not work with rechargeable batteries. It indicates that the battery is low even when they are fully charged. Whereas it asks for a USB power supply 6V, It is very likely that he only works with non-rechargeable batteries, whose nominal voltage 1 .5V, totaling the 6V. Rechargeable batteries have about 1 .2V, What makes only 4, 8V. But, with the power supply, and also using a Power Bank, There were no problems with the 5V voltage supplied.

It is worth noting also that the source is not compatible with the standard Brazilian outlets and you must use an adapter. I ordered the European model. Normally the European models are compatible with Brazilian outlets, but that's not the case. You can choose the model by sending a message to the store. The models available are the European (I), the American (US), the Australian (AU), and the United Kingdom (UK).

I contacted the seller to explain the problem. She apologized, He asked me to check if the interface was making good contact with the batteries. Said that the monitor should be fairly accurate, her mother also uses, that AAA hospitals in Beijing and many other buyers compared with the Omron brand and he is fairly accurate. He asked me to come again, put the arm on the same level as the heart, do not move or talk during the measurements, etc. That still didn't work she'd send me another.

I had already done that way, but just in case I did it again and the same measures appeared too high, in fact even bigger. I got in touch again with the girl and then she offered to send another unit. I accepted.

Unlike the first, that came in the mail from Germany, the second came in the mail from China. When it arrived I did again a unboxing and a test, and took some more pictures, check:

This second Electronic blood pressure monitor also does not work with rechargeable batteries, showing the same problem of charge battery while trying to inflate the bag. But in power supply and Power Bank It also works. The difference is that this second unit shows values that seem real. In all my blood pressure measurements was within the expected, with values considered normal.

Tracing

Check out the first package tracking information, obtained on the website of the AliExpress:

The tracing code that I was passed, with beginning and end UR YP, not present in the trace of the station site in no time. The YP code is not assigned to any country. Apparently this code is used by the company Logistic Yanwen, that must be a carrier that takes the packages from China until the Germany (and maybe other countries) where are shipped in the mail site (DHL in the case of Germany). No site 17Track I was able to get a much more complete tracking:

Final Considerations

And I'm ending here the article on Electronic blood pressure monitor, com uma recomendação positiva para a loja, that made the replacement of the product without any major problems.

As the product, I don't quite know how to evaluate it. The second unit apparently works correctly, but I don't really like the fact that he doesn't work with rechargeable batteries. We must always have an outlet, at POWERBANK or any USB port around to be able to use it. Or use non-rechargeable batteries.
