Description

Defecation assisting pedal device

Technical Field

The invention relates to the technical field of life health care, in particular to a defecation assisting pedal device.

Background

Defecation is one of important daily physiological activities of a human body, the defecation is smooth, wastes and toxins in the body can be cleared timely, good metabolism is maintained, a correct defecation posture is the key point for ensuring the defecation to be smooth and preventing constipation, timely contraction and relaxation of pelvic floor muscles mainly comprising pubic rectal muscles and external anal sphincters under innervation are physiological basis for normally controlling defecation and defecation, at ordinary times, solid excrement is stored in a sigmoid colon or even in a descending colon, the colon and the rectum are relaxed, the pubic rectal muscles and internal and external sphincters are in a tension contraction state, the contraction of the pubic rectal muscles enables the anorectal angle to be maintained at about 90 degrees, at the moment, a tube cavity at the anus-intestine junction is narrow and forms a turning part, the excrement storage is facilitated, and due to the contraction of the muscles, the tube cavity from the colon to the anus keeps a centripetal pressure high at the far end, and a centripetal pressure gradient and a peristaltic wave gradient low at the near heart end, the defecation resistance is larger than the defecation power, so the excrement is stored;

when defecation occurs, the puborectalis muscles, the internal sphincter muscles and the external sphincter muscles are all subjected to reflex relaxation, so that the pressure of an anal tube is rapidly reduced, the muscles of a colon and a rectum contract, the internal pressure of an intestinal cavity is increased, the abdominal muscles also contract to increase the abdominal pressure, the pressure gradient is reversed, the defecation power is greater than the defecation resistance, the rectal angle of the anal tube is opened and enlarged due to the relaxation of the puborectalis muscles, a smooth channel is formed between the rectum and the anal tube, and the defecation is more favorable for discharging excrement out of the anus;

therefore, the maintenance of the relaxation state of the puborectalis muscle during defecation is very important, and research shows that when in a squatting position, the feet and soles touch the ground, the hip joint and the knee joint bend, and the trunk slightly leans forwards, so that the puborectalis muscle can be relaxed to the maximum extent, and the contraction of the abdominal muscle is beneficial to increasing the intra-abdominal pressure and promoting the smooth discharge of excrement, so that the squatting position is the most scientific defecation position, but the long-time squatting can cause numbness and ache of the two lower limbs, and the old people have the phenomena of getting up and strenuous and even falling down, so that the squatting is gradually replaced by the toilet along with the improvement of living level; although the toilet is more comfortable, the sole is not solid due to the backward movement of the gravity center when the toilet is in a sitting position, so that the intra-abdominal pressure is not sufficiently increased when the toilet is defecated; in addition, the flexion of the hip joint and the knee joint is insufficient, so that the pubic rectus muscle cannot be completely relaxed, the anorectal angle is not fully opened, and the defecation power is insufficient, so that the sitting stool is not the optimal defecation posture from the anatomical perspective, particularly, the height of the sitting stool cannot be adjusted, the soles of the feet cannot completely fall to the ground when a person with a short stature sits on the sitting stool, and the disadvantage of the sitting stool is more prominent.
