Definitions

  • the present invention relates to a prosthesis for enterostomy patients.
  • enterostomy i.e. a practice aimed at forming a“stoma”, i.e. a preternatural opening made in the abdominal wall and aimed at connecting any point of the intestine with the outside, so as to allow the discharge of the intestinal contents, i.e. faeces and gas.
  • enterostomy i.e. a practice aimed at forming a“stoma”, i.e. a preternatural opening made in the abdominal wall and aimed at connecting any point of the intestine with the outside, so as to allow the discharge of the intestinal contents, i.e. faeces and gas.
  • bags are currently in use among enterostomized patients that can be applied directly to the stoma and are suitable for the collection of faeces freely escaped outside.
  • this occlusion must be partial in such a way as to prevent faeces from escaping and, at the same time, allow gas to escape.
  • a first type of the above mentioned artificial prosthesis consists of two or more separate parts interacting with each other by simple electromagnetic attraction.
  • these artificial prostheses comprise a magnetized supporting element of substantially annular conformation, which is surgically implanted in the subcutaneous tissue of the patient’s abdomen, at the loop affected by the stoma, and a closing element provided with a metal perimeter band that provides for the occlusion of the stoma associating with the annular element by electromagnetic attraction.
  • a second type of artificial prosthesis based on the same principle of electromagnetic attraction between the parts composing the prosthesis itself, involves bonding to the skin surrounding the stoma of an interchangeable ring on which a magnetized closing element is made to adhere.
  • prostheses consisting of a single monolithic body and made of a rigid and non- deformable material have been developed. These prostheses comprise a tubular element that can be inserted inside the stoma and associated at one end with external retaining means adapted to operate in conjunction with the patient’s body.
  • these retaining means are made in the form of a flange element aimed at abutting against the patient’s skin.
  • the tubular element is provided with locking means comprising a balloon which, by inflating, allows the locking of the tubular element inside the stoma and, by deflating, allows its insertion and extraction.
  • prostheses comprising a tubular element provided with a deformable body at the end inserted inside the stoma, i.e. opposite the external retaining means.
  • a further type of prosthesis has entered production comprising a tubular element associated at one end with a flange element adapted to operate in conjunction with a patient’s body.
  • the tubular element also has an expansible locking element adapted to retain the tubular element itself inside the stoma and substantially shaped like a catheter; in other words, the tubular element has thin walls and a large internal lumen that is used for irrigation to empty the intestinal contents while the tubular element itself is positioned in place, connected to a collection bag.
  • This type of prosthesis may be made both of rigid and soft material.
  • the solution made of soft material is used in serious cases of bedridden patients, the use has been tested by keeping the prosthesis in place inside the stoma for long periods in order to facilitate the maintenance of the ostomy by the personnel in charge, and also to avoid and eventually treat serious injuries of the peristomal or perianal tissues in patients who are not self-sufficient or in coma.
  • This type of prosthesis has not found wide diffusion, and a more evolved model has been created, similar to a catheter aimed at diverting the intestinal content away from the skin surface to avoid the contact of the intestinal content during serious diseases such as burns, ulcerations, infections of the area surrounding the ostomy.
  • prosthetic models are also used in non- self- sufficient and bedridden patients to facilitate ostomy care by medical personnel.
  • a last type of known prosthesis consists of a single monolithic body provided with a hollow tubular element made of rigid material with a first end associated with a flange element and a second end associated with a balloon which, once filled with a fluid, expands beyond the abdominal wall, blocking the prosthesis itself inside the stoma.
  • the continence of faeces and gas is obtained through the inflation of the balloon, while the faeces escape, without deflating the balloon at the end of the device, through the total deflation of the balloon inside the hollow stem; in detail, the collection of faeces is achieved through the association of a containment bag with the flange element, or through irrigation by means of a special integrated system.
  • the aforementioned prosthesis can be anchored inside the stoma for a period not exceeding 28 days, after which the prosthesis must be replaced.
  • the main aim of the present invention is to devise a prosthesis for enterostomy patients adaptable to the positions taken by the patient without causing trouble and discomfort, thus allowing the maximum freedom of movement and increasing, compared to the devices of known type, comfort and practicality of use.
  • Another object of the present invention is to devise a prosthesis for enterostomy patients that significantly increases the quality of life of enterostomy patients.
  • Another object of the present invention is to devise a prosthesis for enterostomy patients which allows controlling the outflow of the intestinal contents allowing patients to use common toilets, including the toilets of the means of transport without the need to dispose of collection bags full of intestinal contents on their own.
  • a further object of the present invention is to devise a prosthesis for enterostomy patients that eliminates the discomfort associated with the need to perform periodic procedures to clean the intestinal contents through the complex and expensive practice of irrigation.
  • Another object of the present invention is to devise a prosthesis that allows overcoming the aforementioned drawbacks of the prior art within a simple, rational, easy, effective to use and affordable solution.
