MC 97υ 00 00 1 7 DESCRIPTION OF A UTILITY MODEL entitled: water closet shaped to allow for the widening of the posterior ano-rectal angle, by Pennesi Sauro, Italian and resident in Macerata at via A. Manzoni n°26, filed on .......... DESCRIPTION TEXT The water closet as we know it and use it today was invented in the second half of the nineteenth century. In fact, the last inventions that led to a hygienic and practical use of the toilet date back to 1870. The invention of the hydraulic seal (with a fixed siphon), replacing the poorly sealed valve seal, marked the beginning of the widespread use of toilets in homes. The hydraulic seal, with a fixed S-shaped siphon, is still used in toilets today because it ensures safe isolation from the drainpipe. The flushing toilet (with a tray above or resting on the toilet), which allows for cleaning and closing the toilet bowl with a single action, is another fundamental invention that has remained universally adopted to this day. Therefore, by the late 19th century, the water closet, now fully developed in its technical and formal aspects, was featured in all technical manuals and the first manufacturers' catalogs, highlighting its functionality, practicality, and hygiene. In the 1930s, vitreous china began to be used, a very hard vitrified ceramic material that was not attacked by acids and which constituted a further advancement. technological and long-lasting guarantee. What is not discussed is the horizontal seat shape, see Table no. 1, it is taken for granted and considered the only suitable one, underestimating an equally fundamental aspect linked to the naturalness of the defecating position and to that complex expulsion mechanism which is closely related to the type of posture. MC 9 7 U 0 0 0 0 017 Today, the seat is horizontal and ranges in height from 30-3 cm for children's toilets to 40-41 cm for adults. This creates an "unnatural" posture that significantly increases the difficulty of evacuating for those who suffer from constipation and can even contribute to its onset in those who do not suffer from this problem. The new patented water closet allows you to comfortably assume and maintain a squatting position similar to the natural one. (See Table 2). The utility model is based on the scientific demonstration that posture influences the physiological mechanism of defecation, determining significant variations in the width of the posterior anorectal angle (PAA). In fact, one of the most important causes of constipation lies in the failure to widen this angle. An anatomical-physiological study was conducted based on the "Working team report" published in the journal Radiol. Med. 85:784-793, 1993. It was the result of a questionnaire concerning defecography submitted by a coordinator to five national experts. The aim was to produce a consensus document. This document showed that the most frequent indication for defecography was by far obstructed defecation, with or without constipation (70%). One of the parameters detected by the examination, with the greatest discriminating power, is the anorectal angle. It is formed by the intersection of the line tangent to the posteroinferior margin of the rectum with the central axis of the anal canal. (Tables 3 and 4). The average values ​​reported in the literature are approximately 90° at rest with a range between 80° and 120°. During emptying, the average value increases to 130° with a range between 115° and 150°. This is necessary for the continence mechanism to resolve and for a funnel to form that is functional for emptying. In scoliosis patients the most common signs in the pathological defecogram are:9 J a) reduction in diameter of the anal canal; b) failure to widen the anorectal angle during evacuation. MC 97U 00 00 1 7 The aim of this study was to evaluate the variations induced on the anorectal angle, under resting conditions, by the position. We considered the sitting position on a 40 cm high vase (Table 1) and the natural position with the patient squatting as if in a "squat system" and therefore in the patented vase that reproduces the almost identical position. (Table 2) The two positions produce a different degree of flexion of the thighs, with the natural position being greater. This difference varies depending on the subject's height and is greater in shorter individuals. The most important result is that the natural position determines an increase in the anorectal angle (probably due to a traction mechanism exerted by the thigh muscles on the perineal fascia) which goes from an average value of 90° to an average value of 120°. (Tables 3 and 4) We believe that the widening of the anorectal angle, which thus approaches values ​​typical of the evacuation phase, is an important element both in normal subjects, where it favors the emptying mechanism, and in constipated subjects, where it removes one of the identified causes, consisting in the failure to widen the anorectal angle itself. The utility model therefore consists of a precise conformation of the toilet, mainly in the part used as a seat, which by determining a correct position of the user as in table 2, allows, while maintaining the comfort of the support, the widening of the posterior anorectal angle without using footrests which modify the position of the feet upwards, (table no. 5) _

Claims

MC 9 / U 0 0 00 1 7 CLAIMS 1) “Water closet shaped to allow the widening of the posterior ano-rectal angle” characterised by the seat inclined in such a way as to determine the widening of the posterior ano-rectal angle with respect to the average value of 90° which is determined by the position on the traditional toilet. 2) “Water closet shaped in such a way as to allow the widening of the posterior ano-rectal angle” according to the claim submitted) characterised by the fact that it does not only determine a generic “physiological position” but a documented widening of the posterior ano-rectal angle which resolves one of the main causes of constipation. 3) “Water closet shaped in such a way as to allow the widening of the posterior ano-rectal angle” according to the claim subì) is characterised by the fact that to determine the widening of this angle, no use is made of a footboard or similar placed next to or integrated with the toilet, which by allowing the feet to be raised from the ground can determine a similar effect, but exclusively of the shape of the toilet in those parts which determine the correct posture, mainly in the part used as a seat.
