Benefits of technology

The swirling motion within the hollow elastic element ensures effective protection against contamination and fluid stagnation, allowing for efficient cleaning and maintaining fluid integrity in medical lines.

Problems solved by technology

With this arrangement, the intermediate tubular connector is difficult to clean before use and can thus be exposed to risks of contamination from the external environment.
However, the axially extended inner cavity of the hollow elastic element according to U.S. Pat. No. 5,533,708 would entail, in particular in application to a haemodialysis medical lines, an extensive stagnation dead area and thus the deterioration of the blood, and this would be unacceptable.
This arrangement is disadvantageous due to the conformation and arrangement of the elastic body which also complicates the traversing thereof by a fluid introducer fitted into the intermediate tubular connector.

Embodiment Construction

[0020]The example represented in the drawings refers to the application of the invention to a haemodialysis medical line. However, it should be observed that the invention is equally advantageously applicable to any liquid flow line revealing the same technical drawback.

[0021]With reference to the drawings, and in particular to FIGS. 1-3, the flow component for haemodialysis medical lines according to the invention essentially comprises a body made of moulded plastic material 1 that forms, in a single piece, a duct 2 having a first end tubular connector 3 and a second end tubular connector 4 coaxial to each other and interconnected by means of a small diameter portion 5 of the duct 2, according to a substantially converging-diverging configuration.

[0022]The end connectors 3 and 4 are designed to be connected, in use, to ducts respectively connected to a haemodialysis machine and to a patient subjected to haemodialysis.

[0023]At the small diameter portion 5, the body 1 forms a circula...

Abstract

A flow component particularly for haemodialysis medical lines includes a duct having a first and a second end tubular connector coaxial to each other and designed to be connected to the line, and an intermediate tubular connector of the female luer type arranged orthogonally to the duct. A hollow elastic element substantially extends along the entire intermediate tubular connector and the body is internally configured so that, in use, the flow along the duct is partly diverted towards the intermediate tubular connector and introduced with a swirling motion along the cavity of the hollow elastic element.

Description

FIELD OF THE INVENTION[0001]The present invention generally refers to liquid flow lines, particularly but not exclusively haemodialysis medical lines and more in particular it regards a flow component for lines thus made of the type comprising a body defining a duct having a first and a second end tubular connector coaxial to each other and designed to be connected to the line, and an intermediate tubular connector arranged orthogonally to the duct between said end connectors and containing a valve device.STATE OF THE PRIOR ART[0002]A flow component of the type defined above is for example known from document EP-1661599B1 on behalf of the Applicant, in which the valve device consists in a hollow elastic element which normally holds said intermediate tubular connector closed and it is elastically deformable following the coupling of the intermediate tubular connector with a complementary male luer connector to enable the introduction of a secondary liquid in the duct. The hollow elas...
