Abstract
Fluid flow control devices for medical use are disclosed. On one end, a fluid flow control device is configured to be attached to a manifold that is in-line with an infusion setup and the other end of the fluid flow control device is configured to be attached to a sampling or infusion device, such as a syringe. In one aspect, a fluid flow control device has an external casing and an internal casing which is configured to be movably housed within the external casing. The internal casing mates with a fluid outlet on the external casing and upon separating the internal and external casings a fluid flow path is established.
Claims16
A fluid flow control device for medical use, the device comprising:
- an external casing configured to attach to an intravenous device, intra-arterial device, or intrathecal device;
- an internal casing configured to be movably housed within the external casing;
- a locking mechanism configured to prevent separation of the internal and external casings, wherein the locking mechanism comprises a locking clip configured to be separable from the external and internal casings by sliding the locking clip orthogonal to a longitudinal axis of the device;
- and
- a base attached to the internal casing, wherein the base is configured to mate with a port of a fluid transfer device;
- wherein the external casing further comprises a groove having an opening configured to lead to a part of the internal casing;
- and wherein the locking clip is configured to be received in the opening by sliding the locking clip orthogonal to the longitudinal axis of the device thereby limiting longitudinal movement of the internal casing in relation to the external casing to prevent the internal and external casings from separating completely while allowing limited longitudinal movement to transition the device from the closed position to the open position and from the open position to the closed position.

A system incorporating a medical fluid flow control device, the system comprising:
- a fluid flow control device comprising:
- an external casing;
- an internal casing configured to be movably housed within the external casing;
- and
- a locking mechanism configured to prevent separation of the internal and external casings, wherein the locking mechanism comprises a locking clip configured to be separable from the external and internal casings by sliding the locking clip orthogonal to a longitudinal axis of the device;
- and
- a base attached to the fluid flow control device, wherein the base is configured to mate with a port of an intravenous device, intra-arterial device, intrathecal device, or fluid transfer device;
- wherein the external casing further comprises a groove having an opening configured to lead to a part of the internal casing;
- and wherein the locking clip is configured to be received in the opening by sliding the locking clip orthogonal to the longitudinal axis of the device thereby limiting longitudinal movement of the internal casing in relation to the external casing to prevent the internal and external casings from separating completely while allowing limited longitudinal movement to transition the device from the closed position to the open position and from the open position to the closed position.
