Abstract

Medical apparatus intended to insufflate air into the colon being repositioned, until intestinal invagination, or "self-introduction of the intestine into itself" is eliminated, this being a physiological occurrence inflicting especially young children, and which often requires surgical operation. The compact apparatus is composed of: A/ A motor or minicompressor with an elastic diaphragm producing pressurised air. B/ An electronic manometer with digital display, which is specially adapted, and is used to measure and monitor this pressure, and which consists of a modern monolithic pressure transducer integrated circuit (basic element) with its corresponding electronic circuit, as well as a L.C.D. indicator; the measurement unit employed is mm of mercury (this being the most suitable in this case). C/ A rapid decompression valve. D/ A high-capacity air tank. The NEUMOCOLON principally allows the intestine to be returned to its correct position, and thus any surgical operation to be avoided in more than 90% of cases.

Description

DESCRIPTION
La présente invention dénommée NEUMOCOLON concerne un appareil d'insufflation d'air dans le colon réduisant jusqu'à supprimer l'invagination intestinale, ceci dans le domaine de la médecine, particuliérement en pédiatrie (nourissons, enfants en bas age).DESCRIPTION
The present invention called NEUMOCOLON relates to an apparatus for blowing air into the colon reducing to the point of suppressing intestinal intussusception, this in the field of medicine, particularly in pediatrics (infants, young children).

L'invagination intestinale est une maladie connue depuis l'ère pré-chirurgicale (16è siècle environ) et relativement fréquente chez les enfants en bas âge qui se définit comme une " autointroduction de l'intestin dans lui même". Intestinal intussusception is a disease known since the pre-surgical era (around 16th century) and relatively frequent in young children which is defined as "self-introduction of the intestine into itself".

Dés la connaissance de cet accident physiologique, divers moyens et/ou méthodes ont été recherchés afin de remettre cet intestin à sa place: bâton flexible à travers l'anus, la "traite" de l'intestin à travers la peau, intervention chirurgicale, lavement baryté à pression, insufflation d'air par l'anus au moyen de divers appareils plus ou moins rudimentaires ou au moyen d'une "poire" (Références bibliographiques: Fiorito et collaborateurs, revue "Pediatrics" de 1959,24,241-244 et She
Ya-Xiong, revue "Chirurgie Pédiatrique" de 1982,23:373-378); toutefois la tendance actuelle est à l'opération chirurgicale que continuent de pratiquer bien des chirurgiens sur ces enfants en bas âge atteints de cette maladie.As soon as knowledge of this physiological accident, various means and / or methods have been sought in order to put this intestine in its place: flexible stick through the anus, the "milking" of the intestine through the skin, surgical intervention, pressure barium enema, blowing air through the anus using various more or less rudimentary devices or using a "pear" (Bibliographic references: Fiorito et al., "Pediatrics" journal from 1959,24,241-244 and She
Ya-Xiong, review "Pediatric Surgery" of 1982,23: 373-378); however, the current trend is for surgery, which many surgeons continue to perform on these young children with this disease.

L'invention consiste en un appareil composé principalement par: A/Un moteur ou minicompresseur à membrane, alimenté à l'électricité qui produit de l'air à pression. The invention consists of an apparatus mainly composed of: A / A motor or membrane mini-compressor, supplied with electricity which produces air under pressure.

B/Un manomètre électronique à visualisation digitale spécialement adapté servant à mesurer et controler parfaitement et en permanence cette pression. B / An electronic manometer with digital display specially adapted to measure and control this pressure perfectly and permanently.

C/Une valve de sécurité de décompression rapide. C / A quick decompression safety valve.

D/Un réservoir à air de grande capacité. D / A large capacity air tank.

E/Un tube pourvu d'une sonde. E / A tube fitted with a probe.

Il a été employé un minicompresseur à membrane élastique avec un dépôt de capacité adéquate pour atténuer les variations de pression produites par le compresseur et permettre une montée lente, progressive et stable de cette pression. En dérivation et comme indiqué sur le diagramme de bloques (fig. 1 et 2), il a été installé un compteur digital ajusté au mm/Hg et qui consiste en un moderne circuit intégré (C.I.); trans'ducteur de pression monolitique comme élément fondamental, avec son correspondant circuit électronique et un indicateur à L.C.D. (L > iquid Cristal
Display) sensible à 1 mm/Hg, il a été employé cette unité car elle parait la plus adéquate pour l'utilisation que doit avoir le dispositif; comme la pression doit être entre 80-120 mm/Hg (à l'extrême 60-180 mm/Hg) et devant la possibilité d'avoir besoin d'un vide rapide du circuit intestinal, il a été installé une valve de décompression qui effectue cette opération avec une grande rapidité.An elastic membrane minicompressor was used with a deposit of adequate capacity to attenuate the pressure variations produced by the compressor and allow a slow, gradual and stable rise in this pressure. As a bypass and as indicated on the block diagram (fig. 1 and 2), a digital counter has been installed adjusted to mm / Hg and which consists of a modern integrated circuit (IC); monolithic pressure transducer as a basic element, with its corresponding electronic circuit and an LCD indicator (L> iquid Crystal
Display) sensitive to 1 mm / Hg, this unit has been used because it seems the most suitable for the use that the device must have; as the pressure must be between 80-120 mm / Hg (in the extreme 60-180 mm / Hg) and in front of the possibility of needing a rapid vacuum of the intestinal circuit, a decompression valve was installed which performs this operation very quickly.

L'amélioration de cet appareil (par rapport aux antérieurs étudiés) réside dans la captation de la pression, le traitement du signal qui en résulte, et la visualisation finale, le tout se réalisant par des moyens totalement électroniques. The improvement of this device (compared to the previous studied) lies in the pressure sensing, the signal processing which results from it, and the final visualization, the whole being realized by totally electronic means.

Pour préciser ce procesus, il a été recherché que la pression fournie par l'appareil soit captée à travers un transducteur transformant directement une variable physique, dans notre cas une pression, en une variable électrique (voltage). To clarify this process, it was sought that the pressure supplied by the device is captured through a transducer directly transforming a physical variable, in our case a pressure, into an electric variable (voltage).

Posterieurement le signal en résultant se traite par des moyens électroniques afin de l'amplifier, compenser la température, et adapter ce signal à l'échelle du mm/Hg, et enfin visualiser le tout au moyen d'un voltimétre digital (L.C.D.). Subsequently, the resulting signal is processed by electronic means in order to amplify it, compensate for the temperature, and adapt this signal to the scale of mm / Hg, and finally visualize everything by means of a digital voltimeter (L.C.D.).

Il faut noter que le NEUMOCOLON (figure 3) doit être utilisé simultanément avec un appareil de radioscopie ou télécommande afin d'observer et controler l'évolution et la réduction de l'invagination intestinale. It should be noted that the NEUMOCOLON (Figure 3) must be used simultaneously with a fluoroscopy device or remote control in order to observe and control the evolution and reduction of intestinal intussusception.

Le NEUMOCOLON a pour objet de défaire l'invagination intestinale. The purpose of NEUMOCOLON is to defeat intestinal intussusception.

L'appareil va produire par envoi d'air sous pression, une force de sens contraire qui ramènera l'intestin à sa situation normale d'origine (figure 4). The device will produce by sending pressurized air, a force of opposite direction which will bring back the intestine to its normal situation of origin (figure 4).

Cet accident physiologique se produit chez l'enfant de forme "idiopathique", c'est à dire qu'il n'a pas de cause explicable dans 90% des cas. This physiological accident occurs in children of the "idiopathic" form, that is to say that there is no explainable cause in 90% of the cases.

Le NEUMOCOLON permet principalement d'éviter toute opération chirurgicale et leurs possibles complications. The NEUMOCOLON mainly allows to avoid any surgical operation and their possible complications.

Depuis l'enregistrement de la patente espagnole plusieurs améliorations et perfectionnements ont été apportés au prototype d'origine, qui feront l'objet d'additions ultérieures, en Espagne et en France. Since the registration of the Spanish patent, several improvements and improvements have been made to the original prototype, which will be the subject of later additions, in Spain and France.
