Abstract
Some embodiments are directed to a connector for connection with a fluid transfer device, including an outer body having a longitudinal axis; and a luer lock connection port positioned within the outer body and configured to be coupled with an external port of said fluid transfer device. The luer lock connection port can be rotatable about the longitudinal axis at least in one of a clockwise direction and a counter-clockwise direction at least prior to initiation of coupling thereof with the external port. The outer body can be structured, and the luer lock connection port is positioned therewithin, such that to prevent an operator to access, through the outer body, directly by fingertips an exterior of the luer lock connection port after the luer lock connection port has been coupled with the external port.
Core Innovation
The disclosed invention relates to a connector for connection with a fluid transfer device. The connector includes an outer body having a longitudinal axis and a luer lock connection port positioned within the outer body, configured to be coupled with an external port of the fluid transfer device and rotatable about the longitudinal axis in a clockwise direction as well as a counter-clockwise direction at least prior to initiation of coupling.
The outer body and the luer lock connection port are structured such that an operator is prevented from accessing, through the outer body, directly by fingertips an exterior of the luer lock connection port after the luer lock connection port has been coupled with the external port. A decoupling facilitating mechanism selectively assumes a decoupling disabled state and a decoupling enabled state.
In the decoupling disabled state, the decoupling facilitating mechanism allows rotation of the luer lock connection port at least in the counter-clockwise direction. In the decoupling enabled state, the mechanism restricts rotation of the luer lock connection port at least in the counter-clockwise direction so as to allow decoupling of the external port from the luer lock connection port. The disclosure further describes integrating the connector into an adaptor for medical fluid transfer devices with a distal septum configured to receive at least one syringe needle, and adaptor valve arrangements for spill/pressure control.
Claims Coverage
The identified independent claim covers 3 inventive features directed to a tamper-proof luer-lock connector with selective control of counter-clockwise rotation for decoupling.
Tamper-proof outer body preventing fingertip access to luer lock port exterior
An outer body having a longitudinal axis structured to prevent an operator from accessing, through the outer body, directly by fingertips an exterior of the luer lock connection port after coupling with the external port.
Rotatable luer lock connection port about the longitudinal axis for coupling
A luer lock connection port positioned within the outer body, configured to be coupled with an external port of the fluid transfer device, and rotatable about the longitudinal axis in a clockwise direction as well as a counter-clockwise direction at least prior to initiation of coupling.
Decoupling facilitating mechanism with decoupling disabled and enabled states
A decoupling facilitating mechanism configured to selectively assume a decoupling disabled state that allows counter-clockwise rotation and a decoupling enabled state that restricts counter-clockwise rotation so as to allow decoupling of the external port from the luer lock connection port.
The inventive concept combines a luer-lock connector with an outer body that prevents fingertip access to the coupled port exterior and a decoupling facilitating mechanism that selectively controls at least counter-clockwise rotation to enable decoupling.
Stated Advantages
Prevents an operator from accessing, through the outer body, directly by fingertips an exterior of the luer lock connection port after coupling.
Restricts counter-clockwise rotation of the luer lock connection port in a decoupling enabled state so as to allow decoupling of the external port from the luer lock connection port.
Documented Applications
An adaptor for medical fluid transfer devices including a connector as a proximal portion and a distal septum configured to receive at least one syringe needle.
Spill/pressure control for adaptor valve arrangements using dual valves with threshold-based, normally closed, automatically actuated sealing members.
Protocol enforcement using actuator-controlled operational/inoperational states by blocking liquid transfer directly or indirectly via air-channel valve control.
