Problems solved by technology

The chip in the existing invasive pressure sensor is usually fixed on the inner wall of the casing by glue, and there is no fixing structure on the casing, it is difficult to fix the chip to the designated position, and the efficiency of chip fixing is low
In addition, when such a structure is used, it also makes the chip vulnerable to the influence of external signal lines, which affects the accuracy of the stress test.

Abstract

The invention discloses a pressure detection assembly and an invasive pressure sensor. The pressure detection assembly is used for the invasive pressure sensor. The pressure detection assembly comprises a shell, wherein a pipeline channel is formed in the shell, a containing cavity is further formed in the shell, a mounting groove is formed in the inner wall of the containing cavity, a connectinghole is formed in the groove bottom wall of the mounting groove, the connecting hole is communicated with the pipeline channel, and a chip is fixedly connected with the groove wall of the mounting groove and is close to the connecting hole. According to the chip of the pressure sensor in the technical scheme of the invention, the chip fixing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a pressure testing component and an invasive pressure sensor with the pressure testing component. Background technique [0002] Invasive pressure sensors have been widely used in hospital operating rooms, anesthesiology departments, intensive care, etc. There is a pressure test fluid flowing inside the invasive pressure sensor, and its end is connected with the blood vessels of the human body to provide continuous dynamic monitoring of the human body to directly obtain Vascular arterial pressure, central venous pressure, pulmonary artery pressure, left coronary artery pressure and other physiological parameters provide objective basis for clinical diagnosis, treatment and prognosis estimation of diseases. The chip in the existing invasive pressure sensor is usually fixed on the inner wall of the casing by glue, and there is no fixing structure on the casing, so it is ...
