Description

Technical Field

[0001] The invention relates to the technical field of life health care, and in particular to a defecation assisting pedal. Background Art

[0002] Defecation is one of the important daily physiological activities of the human body. Smooth defecation can timely remove waste and toxins from the body and maintain a good metabolism. Correct defecation posture is the key to ensuring smooth defecation and preventing constipation. The timely contraction and relaxation of the pelvic floor muscles, mainly the puborectalis and the external anal sphincter, under the control of nerves is the physiological basis for normal defecation control and defecation. Usually, solid feces are stored in the sigmoid colon or even the descending colon, the colon and rectum are relaxed, the puborectalis and the internal and external sphincters are in a state of tension and contraction, and the contraction of the puborectalis maintains the anorectal angle at about 90 degrees. At this time, the lumen at the anorectal junction is narrowed and forms a turn, which is conducive to the storage of feces. In addition, due to the contraction of the above muscles, the lumen from the colon to the anus maintains a centripetal pressure gradient and peristaltic wave gradient with high pressure at the distal end and low pressure at the proximal end, resulting in defecation resistance greater than defecation power, so feces can be stored;

[0003] During defecation, the puborectalis muscle, internal sphincter, and external sphincter all relax reflexively, causing the anal canal pressure to drop rapidly. The rectal and rectal muscles contract, increasing the intestinal pressure. The abdominal muscles also contract, increasing the abdominal pressure. The above pressure gradient is reversed, and the defecation power is greater than the defecation resistance. In addition, due to the relaxation of the puborectalis muscle, the anorectal angle opens and becomes larger, forming a smooth passage between the rectum and anal canal, which is more conducive to the discharge of feces from the anus.

[0004] Therefore, it is very important to maintain the relaxation of the puborectalis muscle during defecation. Studies have shown that when squatting, the soles of the feet are on the ground, the hip and knee joints are flexed, and the trunk is slightly tilted forward. This posture can relax the puborectalis muscle to the greatest extent, and the contraction of the abdominal muscles helps to increase the intra-abdominal pressure and promote the smooth discharge of feces. Therefore, squatting is the most scientific defecation posture, but squatting for a long time can cause numbness and soreness in both lower limbs. The elderly have difficulty standing up and even fall. Therefore, with the improvement of living standards, sitting toilets have gradually replaced squatting toilets. Although sitting toilets are more comfortable, the center of gravity moves backward when sitting, and the soles of the feet are not firmly on the ground, resulting in insufficient increase in intra-abdominal pressure during defecation. In addition, the inadequate flexion of the hip and knee joints leads to the inability of the puborectalis muscle to relax completely, the anorectal angle is not fully opened, and the defecation power is insufficient. Therefore, from an anatomical point of view, the sitting toilet is not the best defecation posture, especially the height of the toilet cannot be adjusted, and the soles of the feet of short people cannot completely touch the ground when sitting on it, which further highlights the disadvantages of sitting toilets.

[0038] The upper surface of the foot pedal 1 is covered with a rubber layer, and the rubber layer is lined with velvet, so that people feel comfortable when stepping on it; the upper surface of the foot pedal 1 is symmetrically provided with an inwardly concave foot pedal surface 5, and the foot pedal surface 5 is provided with a raised Yongquan acupoint massage point 6, and the Yongquan acupoint massage point 6 is a hard rubber hemispherical protrusion with a protrusion diameter of 1 cm. The protrusion is made of hard rubber material, so that it can massage the Yongquan acupoint of the sole of the foot during defecation, and the long-term effect can enhance the physical fitness and keep the defecation smooth; the Yongquan acupoint of the sole of the foot is one of the most important acupoints of the human body, and regular massage can regulate the autonomic nervous system, activate kidney qi, accelerate the discharge of toxins, and treat defecation difficulties; the Yongquan acupoint is located at the front 1 / 3 of the line connecting the second and third toe seams and the heel, or the concave area of ​​the sole of the foot when the toes are bent forcefully; the raised acupoint site (Yongquan acupoint) is designed on the foot pedal surface according to the position of the sole of the foot, so that the sole of the foot can get the effect of acupoint massage when stepping on the foot pedal, thereby achieving the effect of further promoting defecation;

[0039] A rubber pad is provided at a dead angle on the lower surface of the base 2 to prevent slipping, so as to prevent the pedal from being loosely fixed or slipping when pedaling hard;

[0040] The bottom and periphery of the footrest 1 are made of metal and hard plastic, which are strong and durable. The corners of the footrest are all designed in an arc shape without sharp raised corners, which can prevent accidental damage. In addition, the upper surface of the footrest is coated with a thin layer of rubber and lined with suede, which can keep the soles of the feet warm.

[0041] The defecation assist device has an inverted trapezoidal three-dimensional structure as a whole, with a size of about 618mm (length) * 300mm (width) * 300mm (height), and the center of the inner bottom edge is designed to be fan-shaped, making the overall appearance more beautiful and lightweight.

[0042] Compared with the traditional squat toilet, the existing toilet is more comfortable when used. However, during use, the center of gravity moves backward when sitting, and the soles of the feet are not firmly on the ground, resulting in insufficient increase in intra-abdominal pressure during defecation; in addition, the hip and knee joints are not fully flexed, resulting in the inability to completely relax the puborectalis muscle, incomplete opening of the anorectal angle, and insufficient defecation power. Therefore, from an anatomical point of view, the toilet is not the best defecation posture; and when a person sits on the toilet to defecate, his or her body trunk is at 90 degrees, which is not conducive to the discharge of feces. When using the defecation booster designed by the present invention for defecation, by adjusting the inclination and height of the foot pedal 1, the puborectalis muscle can be completely relaxed, the anorectal angle can be fully opened, the defecation power is sufficient, and the user can defecate conveniently.
