Many heart valve repairs do not require large-scale open heart surgery. Transcatheter aortic valve repair (TAVR) is now a more common method, which is a less invasive option for many patients with weak body. TAVR also faces certain risks during the operation. During the operation, the embolic fragments will be released. These fragments will pose serious risks to many tissues and organs of the body, especially the brain. These fragments will block the blood vessels in the blood. If it occurs in the brain, it will cause a stroke. . Is there a way to prevent the fragments produced during surgery from entering the external circulatory system during surgery? The FDA recently approved a sentinel brain protection system to prevent the risk of stroke in this TAVR procedure. This system comes from Claret Medical. Schematic diagram of the process of implanting the sentinel system. (Source: Claret Medical) The sentinel system is a percutaneous device that contains two filters that are delivered to the target location in a very subtle way, one of which is the brachiocephalic artery and the other is the left common carotid artery. The device was inserted from the right arm right iliac artery and placed at the junction of the brachiocephalic artery and the left common carotid artery. Dangerous debris will be trapped by the filter of the device, after which the captured debris will be removed from the right arm along with the device. This sentinel system can be used in any procedure during TAVR, regardless of whether the valve is being implanted or not, and does not interfere with the procedure. The large embolic particles were taken out after TAVR. (Source: Claret Medical) Water Test Strips 15 Parameters Detection method:
2. Put the edge of the strip against the edge of the container to remove excess water samples;
3. Compare the test strip with the colorimetric table on the bottle label, and record the test result in the determination time: 0 ~ 60 seconds. Use visual.

Operation method:
1. Visual inspection: Immerse the test area of the test paper into the fully stirred fresh drinking water, and take it out immediately;
The test paper should be stored in room temperature, dry environment, away from a variety of chemical reagent environment, avoid direct sunlight. This product does not need to be refrigerated (if it is stored for a long time, it should be restored to room temperature and opened for use).
