| The large mouse non-invasive blood pressure meter is mainly composed of three parts, one is the detection unit, one is the insulation unit and the other is the software system. With the increasing use of large mouse non-invasive blood pressure monitors in the fields of drug toxicology, drug monitoring, and hypertension research, the non-invasive blood pressure monitors of different brands and designs in the market are constantly being updated, facing various performances. Products, how to choose when you buy?  Before buying the instrument, I suggest that you get out of the two misunderstandings that are familiar with the big mouse non-invasive blood pressure meter:  Myth 1: The more instrument channels, the better.  With the increasing use of non-invasive blood pressure monitors in large mice, many domestic manufacturers have introduced 6-channel, 8-channel or even 12-channel large mouse non-invasive blood pressure monitors. Some people accidentally walked into the misunderstanding of "the more channels the better" . In fact, the detection of the instrument can be completed in an instant. The main time-consuming measurement of blood pressure is in the fixation and heat preservation of the animal. It is particularly important to confirm whether the fixation and heat preservation of the non-invasive blood pressure meter of the large mouse before purchase are reasonable. It is not possible to simply listen to the number of publicity channels.  Myth 2: Heating is fast.  The large mouse itself is very sensitive to the ambient temperature and humidity. It can't withstand the sudden changes of temperature and the excessive temperature. When warming, the reaction of the big mouse should be considered. There is also a little mouse that has no sweat glands, and the heart rate is accelerated when the temperature is too fast. Gradually warming up allows large mice to adapt to the test environment as quickly as possible in order to obtain true and reliable measurement data.  When we go out of the mistakes and want to choose a large mouse non-invasive blood pressure monitor that best suits our needs, what should we pay attention to?  1. The detection part of the instrument  At present, the detection principle of the non-invasive blood pressure meter for large mice on the market is basically the Tail-Cuff method. The key is to look at the repeatability of the instrument; the authenticity of the data; the recognition of the user.  2. Fixing and insulation system  When measuring the blood pressure of large mice, we will encounter many problems. For example, the measured large mice cannot adapt to the environment and the blood pressure is not representative. The vibration waves generated by blood pressure are difficult to detect or contain noise. The large mice are The turbulence in the measurement process destroys the measurement process. For the non-invasive blood pressure detection system, the design of the product is conducive to the stability of the large mouse to avoid the accuracy of the results caused by the rat's panic. Each design has its own uniqueness but also has unavoidable shortcomings. This is what we often say is "rat-like".  3. Software section  Whether the operation is convenient, whether the heart rate fluctuation of large mice can be detected in real time. Whether the software data has been verified by a large number of experiments, whether the data is automatically processed, stored, statistically analyzed, and analyzed.  |
