CONNECTEUR POUR TUBULURE MEDICALE ET POCHE POUR SOLUTION MEDICALE UTILISANT CE CONNECTEUR. LE CONNECTEUR SELON LA PRESENTE INVENTION COMPREND UN ELEMENT MALE A EN MATIERE A L'EPREUVE DE LA CORROSION ET RESISTANTE A LA CHALEUR, CET ELEMENT ETANT CONNECTE A L'EXTREMITE DE TUBES SOUPLES P, P A RACCORDER MUTUELLEMENT ET COMPORTANT UNE EXTREMITE D'INSERTION 12 AINSI QU'UN PASSAGE INTERIEUR 18; UN ELEMENT FEMELLE B EN MATIERE A L'EPREUVE DE LA CORROSION ET RESISTANTE A LA CHALEUR, CET ELEMENT CONNECTE A L'AUTRE DES DEUX TUBES SOUPLES P, P ET COMPORTANT UNE EXTREMITE D'INSERTION 22 AINSI QU'UN PASSAGE INTERIEUR 24. L'ELEMENT MALE DE CONNECTEUR COMPORTE UNE PARTIE D'ASSEMBLAGE 12A ET UNE MATIERE AYANT UN COEFFICIENT DE DILATATION THERMIQUE PLUS PETIT QUE CELUI DE LA MATIERE FORMANT UNE PARTIE D'ASSEMBLAGE DUDIT ELEMENT FEMELLE DE CONNECTEUR. CES ELEMENTS DE CONNECTEUR SONT ASSEMBLES L'UN A L'AUTRE ET SEPARES L'UN DE L'AUTRE GRACE A UN ASSEMBLAGE PAR CONTRACTION. A connector for medical tubing for liquid transfusion includes a short tubular male connector member made of thermally resistant corrosionproof materia; a short tubular female connector member made of thermally resistant corrosionproof material; and a fitting surface portion on the outer surface of an insertion end of the male connector, shaped in the male form and made of a material having a smaller thermal expansion coefficient than the material of a corresponding fitting surface portion on the inner surface of an insertion end of the female connector shaped in the female form. The fitting surface portion of the insertion end shaped in the male form, and the fitting surface portion of the insertion end shaped in the female form, are of relative sizes such as to permit the insertion ends to be connected to and separated from each other by shrink fit utilizing the difference between the thermal expansion coefficients thereof. A medical solution bag device using the connector is also disclosed.
