1results about How to "Prevent thrombosis" patented technology

This application provides a blood pressure sensor, comprising: a tubing having a first end and a second end disposed opposite to each other, the first end being for connecting to a blood vessel, and the second end being for injecting a pressure measuring medium; a pressure sensor disposed in the tubing and used for measuring the liquid pressure in the tubing; and a filter element installed at the first end, or installed between the first end and the pressure sensor. The filter element is used to filter blood cells in the blood entering the tubing from the first end, while allowing the pressure measuring medium to pass through. In this application, the filter element prevents large particles such as blood cells from entering the tubing, preventing blood cells from agglomerating and forming thrombi in the tubing, and also preventing blood from being flushed back into the blood vessel, causing a series of serious consequences such as arterial embolism, myocardial infarction, and pulmonary embolism. Simultaneously, the filter element allows the pressure measuring medium to pass through, thereby ensuring smooth pressure measurement.
