The invention relates to the technical field of
medical instruments, in particular to a portable
biofeedback instrument for
constipation patients, which comprises a
catheter and a host, the left end of the
catheter is communicated with a
rectum simulation air bag, the surface of the
catheter is provided with an
anal sphincter induction air bag, the right side of the top of the surface of the catheter is provided with a piezoelectric
micropump I, and the left end of the catheter is provided with an
anal sphincter induction air bag; one end of the first piezoelectric
micropump is communicated with the guide
pipe, the other end of the first piezoelectric
micropump is communicated with a water tank, an inner
pipe is arranged in an inner cavity of the guide
pipe, and one end of the inner pipe penetrates to the outer side of the guide pipe and is communicated with a second piezoelectric micropump. The
system has the advantages of high portability, intelligent analysis, personalized training,
data synchronization and remote support; the host of the
biofeedback instrument is in the size of a palm, accords with ergonomic holding, is internally provided with a rechargeable
lithium battery, can be carried and used by a patient anytime and anywhere, does not need to go to a hospital and other professional places, greatly improves the flexibility and convenience of treatment, and saves the time and economic cost of the patient.
