Embodiment Construction

[0019] exist Figure 1 to Figure 4 , Figure 8 and Figure 9 In the illustrated embodiment, the valve connector for infusion medical tubing according to the present invention is substantially similar to the valve connector described and illustrated in the above-mentioned patent document EP-1834665A1 and mainly comprises four elements: the external The tubular body 1; the inner hollow needle 2, which is arranged axially in the cavity of the tubular body 1; the elastic seal 3; and other elements described below. Typically, the tubular body 1 and the hollow needle 2 are made of a moldable rigid plastic material, while the seal 3 is made of an elastic material such as silicone.

[0020] The tubular body 1 has an inlet end 4 shaped like a female luer lock connection to cooperate in a conventional manner with a male luer connection or luer lock connection for fluid introducers such as needle-free syringes. The inlet end 4 is connected to a generally cylindrical middle section 5 f...

Abstract

Valve connector for infusion medical lines including an external tubular body (1) with an inlet end (4) and an outlet end (10), an internal hollow spike (2) and an intermediate sealing member (3) including an elastic head (35) with pre-slit (38) and an elastic hollow element (36) formed with sealing members (47, 48) in contact with the hollow spike (2) and with an elastic thrust means tending to maintain the elastic head (35) in a closure condition. An annular member (55) surrounds the elastic hollow element (36) and it axially slides into the tubular body (1) due to the movement of the elastic head (35) between the closure condition and the opening condition of the connector. Due to this solution idea, the valve connector according to the invention is provided with an improved degree of reliability, guaranteeing the airtight sealing in its activated condition even in case of generation of overpressures therein reaching up to values in the order of 300 psi and above in its activated condition.

Description

technical field [0001] The present invention relates to valve connectors such as medical tubing for infusion through an introducer of fluid infusion substances, in particular to Luer connectors or Luer lock connectors such as needle-free injectors. Background technique [0002] From the European patent application EP-1834665A1 of the same applicant, a valve connector is known as the prior art of the present invention, in which there is provided a tubular body with a cavity, an inlet port designed to cooperate with a liquid guide, and the export port. The hollow needle is disposed axially within the cavity of the tubular body and has a closed end facing and axially spaced from the inlet end of the tubular body. The hollow needle communicates with the outlet end of the tubular body and has a side hole spaced from its closed end for communication with the cavity of the tubular body. The connector also includes a resilient seal comprising a resilient head having a pre-slit dis...
