Capsule type pressure measuring device

Abstract

The invention discloses a capsule type pressure measuring device which comprises a capsule shell, an image acquisition assembly and a liquid column type pressure sensor, the image acquisition assemblyis arranged in the capsule shell, the liquid column type pressure sensor is attached to the outer surface of the capsule shell, and the liquid column type pressure sensor is attached to the outer surface of the capsule shell. And the image acquisition assembly can acquire an image of the liquid column type pressure sensor so as to read a pressure value of the liquid column type pressure sensor. The liquid column type pressure sensor is attached to the outer surface of the capsule shell and does not occupy the internal space of the capsule shell, so that the capsule shell can be made smaller,and the liquid column type pressure sensor occupies little space outside the capsule shell due to the fact that the liquid column type pressure sensor is thin. Therefore, the overall size of the capsule type pressure measuring device can be made smaller.

Description

technical field [0001] The present application relates to the technical field of pressure measurement, in particular to a capsule pressure measurement device with a liquid column pressure sensor. Background technique [0002] Existing capsule manometry devices for measuring digestive tract, uterine or vaginal pressure generally use MEMS (full name in English: Micro-Electro-Mechanical System; Chinese: Micro-Electro-Mechanical System) sensors for measurement, and MEMS sensors require secondary Encapsulation is required to meet the requirements of biocompatibility, but because of the secondary packaging, the range and accuracy of the sensor output are affected, the process procedure is complex, and the volume is large, which is not conducive to the miniaturization of the capsule device. Contents of the invention [0003] In order to overcome the above-mentioned problems in the prior art, the main purpose of the present application is to provide a capsule-type pressure measuri...
