The invention belongs to the field of
medical instruments, and relates to a gastric juice ph detection
stomach tube device. The device comprises a tube body, a detection end and an analysis end, wherein the detection end and the analysis end are respectively connected to the far end and the near end of the tube body and are in communication connection; the tube body is of a multi-layer coaxial structure and sequentially comprises an inner tube, a supporting tube and an outer tube from inside to outside in the radial direction, and the far end of the inner tube is connected with the detection end. The detection end can extend into the
stomach of a
human body to collect gastric juice ph detection signals, the analysis end receives and processes the signals, and efficient, accurate, convenient and real-time detection of gastric juice ph is achieved. The clamped supporting
pipe supports the inner
pipe and the outer
pipe by means of the structural strength of the supporting pipe, it is guaranteed that the pipe body is straight when stretching into the pipe body and stable during working, blockage of a liquid flowing path or position deviation of the detection end is avoided, and stable detection is guaranteed.
