Connector for medical use

A technology of connectors and chambers, which is applied in the field of medical connectors for dispersing fluids. It can solve the problems of not optimal tightness and the inability to ensure the end of the connector to be cleaned, so as to achieve tightness enhancement, improved elastic performance, and pollution risk suppression.

Problems solved by technology

[0012] Further, since the contact surface area between the luer cone of the sampling device or the like and the connector is formed only by the free end of the ring, the tightness between these two elements is not optimal, the two surfaces being made of rigid made of plastic material
[0013] Finally, the discontinuous structure of the free end of the connector, i.e. the alternation of independent materials of different properties (elastic part, ring, space and finally the wall of the chamber) from the center to the periphery, which does not ensure a proper fit after disconnection. Purge the end of the connector

Embodiment Construction

[0045] refer to figure 1 , figure 1 Shown is a medical connector (1) according to the invention comprising means (2) fixed to a chamber (3) and a ring (4) (not shown in this figure) / elastic seal (5) assembly. The device (2) is presented in the form of coupling the actual device (2) and needle (6) (not shown in this figure). The chamber (3) comprises a first chamber (3a), an intermediate chamber (3b) and an end chamber (3c).

[0046] The end chamber (3c) of the chamber (3) has a section capable of receiving a male luer type connector (7) by friction. A first chamber (3a) of the chamber (3) cooperates with the device (2) for receiving a tube conducting fluid. refer to figure 2 , figure 2 Shows a medical connector (1) according to the invention, in longitudinal section, the body of the device (2) comprising a recess (2a) provided on a threaded inner surface of the body of the device (2) to For mating with the corresponding threads of a tube or another female luer-type conne...

Abstract

The invention relates to a connector (1) for medical use. The connector comprises a coupling (2) which is secured to a chamber (3) and provided at the center thereof with a needle (6) of which at least the terminal portion is sheathed, said needle being disposed in the cavity (5g) of a resilient gasket (5) having, in the thickness of the free end thereof, a slot (5d) or equivalent. The resilient gasket (5) is also provided with a ring (4). According to the invention, the terminal end (5c) of the resilient gasket (5) has a deformable peripheral flange (5h) covering the end of the ring (4).

Description

technical field [0001] The present invention relates to the field of medical connectors, and more particularly to medical connectors for dispensing fluids, of the type comprising a chamber secured to a device having a needle, an elastic seal and a ring. Background technique [0002] From patent document EP 1890760 it is known a medical connector having a first end, also called "upstream end", and a second end, which can be connected to a tube conducting fluid; The two ends are also referred to as "downstream ends" which can mate with equipment for sampling or injection through a male Luer connector. Hereinafter, the expressions "upstream end" and "downstream end" will be used regardless of the flow direction of the fluid. [0003] In practice, the connector has a chamber fixed at the base to the means forming the upstream end of the current connector. The free end of the cavity opposite the base can frictionally receive the tip of a luer-type male connector. The flow of f...
