Definitions

  • FIG. 5 shows the longitudinal section of the subject urinary catheter having a wide inner channel
  • the tube-like catheter body 102 is formed with walls 116 defining and circumferentially enveloping an internal channel 115 of the tube-like catheter body 102.
  • reinforcement members 128 made of a malleable material, for example, rubber or plastic with memory which in closed position are positioned parallel to the walls 126 of the retention body 113.
  • the reinforcement members 126 may be welded, glued or otherwise adhered to the wings 126.
  • the plastic rod 122 and the reinforcement members 126 may be glued together to form a one-piece structure.
  • the reinforced wings 126/128 will open from approximately 90 degrees up to approximately 180 degrees when the bellows 120 is stretched, as seen in FIGS. 3B - 3D.
  • the positioning of the urine drainage port 132 of the subject catheter 100 at the bottom of the bladder 134 provides a complete no-residual urine drainage from the bladder 134, coupled with faster drainage of the urinary bladder, and a faster flow through the inner channel 130 of the retention body aligned with the inner channel 115 of the tube-like elongated body 102, thus eliminating conditions favorable for developing irritation and bacteria growth inside the bladder, as well as other urinary passages, that is highly beneficial for the health of the patient.
  • the stabilizer housing 144 is opened by unlocking the latching mechanism 149, 151, and hingedly separating the upper wall 146 from the lower wall 148, and the bellows 120 is removed from the receiving channel 150 of the stabilizer housing unit 144.

Abstract

Cette invention concerne un cathéter ayant un mécanisme de rétention à double action constitué par (a) un mécanisme de rétention comportant un corps de rétention renforcé qui peut être transformé pour adopter une configuration en forme de fleur déployée quand le cathéter est inséré dans la cavité corporelle, et (b) un stabilisateur fixant le cathéter au corps du patient pour le maintenir en position stable. Le mécanisme de rétention pour fixer le cathéter est conçu à l'aide des parties de paroi épaissies ou renforcées du corps de rétention. Le canal interne du corps de cathéter est plus large que les cathéters classiques, pour obtenir ainsi un meilleur drainage et un meilleur écoulement de fluide. Grâce à la configuration en fleur renforcée, tout retrait accidentel du cathéter sous sa configuration de fleur entièrement déployée n'occasionnera aucun endommagement significatif. Quand le cathéter doit être retiré, le corps du cathéter est dégagé du stabilisateur et la configuration en fleur du corps de rétention du mécanisme de rétention s'aplatit de manière contrôlable, transformant ainsi le cathéter en une configuration appropriée pour le retrait du cathéter de la cavité corporelle. Le cathéter amélioré est simple en fonctionnement, sûr, empêche les infections des voies urinaires associées au cathéter (CAUTI), et permet un drainage d'urine non résiduaire et à un débit élevé.
