Embodiment Construction

[0031] Referring to the Figures, the coupling device is generally indicated with 1 . It is used to connect a pair of tubular members at respective ends.

[0032] In the following, the tubular members to be connected should be understood as soft catheters, of the type used in the clinical field. In this embodiment, the coupling device or connector is used to connect the ends of two catheters, one of which is of the CVC type, for example, to perform infusions. Therefore, in this embodiment, the general characteristics of these two catheters will be the general characteristics of a catheter suitable for use in a living body.

[0033] In particular, the first tubular member is composed of a first conduit 2 having a first end 3 with a larger diameter, which is closed by a first cap 4 . Such a first end 3 will be denoted by the term "receiving end" hereinafter. A cap 4 is intended to be assembled on the outside of said tip 3 .

[0034] In this embodiment, the coupling device 1 i...

Abstract

A coupling device (1) for connecting two ends (3, 9) of respective tubular members, allow the opening and the closing of a first tubular member and the simultaneous engagement of the two tubular members, in such a way preventing any pollution, comprises: a first case (5) housing a first end (3) of a respective first tubular member (2), comprising closing means (10) of said first end (3); a secondcase (20), wherein a flexible terminal section (6) of a respective second tubular member is received, comprising means for driving a second end (9) of said second tubular member from a retracted position to a engagement position into said first end (3) and vice versa; and means for reversibly connecting said first and second cases (5, 20) at a respective coupling port thereof, defining a single sealed environment; wherein the engagement and the disengagement of said second end (9) and the automatic mechanical activation and deactivation of said closing means (10) for opening and closing said first end (3).

Description

Background technique [0001] The present application relates to coupling devices, in particular coupling members for the connection of the two ends of respective tubular members in order to establish continuity from one end to the other. [0002] The invention also relates to the use of said device, in particular for the connection of a catheter for insertion into a living body, in particular a human body, to pass through said catheter and through a hose connected thereto, to perform operations related to The process of withdrawing fluid from and / or injecting fluid into a living body. [0003] A specific embodiment consists of a joint of a catheter introduced into the interior of the human body for transfusion. [0004] A prominent disadvantage of the existing device is that it cannot with absolute certainty prevent contact between fluid flowing through the two hoses and the connection between them and even the smallest surface which has previously been exposed to the open env...
