The present invention relates generally to fluid connection devices, and more particularly to fluid connection devices that may be connected and disconnected.
Fluid connection devices may be implemented in a variety of applications where fluid flows from one location to another. Examples of suitable applications for a fluid connection device may be found in the medical field. Generally, fluid lines are used to deliver various fluids between two entities. For example, fluid lines may be used to deliver medicine to a patient, to draw blood from the patient, or to connect a fluid dispensing device to a tube set for delivery.
Conventional fluid connection devices generally include a male connection end that is insertable into a complementary female connection end. However, conventional male and female connectors may be deficient in that the connectors may not be configured to provide a sanitary or aseptic connection, allowing the fluid to become contaminated from bacteria, viruses, or other microorganisms. A particular issue with contamination in medical connection devices is associated with when the two connection ends are disconnected. Biological material can leak during disconnection which can present a serious biohazard.
The present application is directed towards a fluid connection device that includes a first connector having a key portion that is engageable with an actuatable portion of a second connector. The fluid connection device maintains a sanitary, tamper-resistant connection between the first and second connector, and the second connector may reseal itself when the first connector is disconnected from the second connector.
A fluid connection device may include a first connector having at least one fluid passage, a second connector having at least one fluid passage, the second connector initially being in a closed position, and a key associated with the first connector for actuating the second connector. The second connector may be moveable to an open position when actuated by the key, and the first connector may be insertable into or otherwise joined with the second connector when the second connector is in the open position. The at least one fluid passage of the second connector and the at least one fluid passage of the first connector may be adjacently aligned and in fluid communication when the first connector is fully inserted into or joined with the second connector.
A fluid connection device may include a first connector having at least one fluid passage, a second connector having a housing, at least one fluid passage contained within the housing, and a receiving chamber contained within the housing for receiving the first connector, the receiving chamber being in fluid communication with the at least one fluid passage and having at least one sealing door that may be opened and closed, and a key associated with the first connector for opening the sealing door of the receiving chamber. The sealing door of the receiving chamber may be opened when actuated by the key and the first connector may be inserted in the receiving chamber when the sealing door is opened. The at least one fluid passage of the second connector and the at least one fluid passage of the first connector may be in fluid communication when the sealing door is opened and the first connector is fully inserted in the receiving chamber.
A method of providing fluid communication between fluid passages in a first connector and a second connector may include arranging the second connector in an initially closed position, the second connector having a sealing door. The method may further include actuating the second connector using a key associated with the first connector, wherein the sealing door of the second connector opens in response to recognition of the key. The method may still further include inserting the first connector in the second connector, or otherwise joining the first connector with the second connector, when the sealing door is opened, wherein the fluid passages are in fluid communication when the first connector is fully inserted in or joined with the second connector, when the second connector is in an open position.
The principles of the present application have particular application to connecting fluid lines. More particularly, the present application is directed towards connecting fluid lines used in medical applications. Other suitable applications may include any application that uses hydraulic lines that are to be connected for delivering fluid between separate entities, such as fluid sources. The fluid connection device may include a first connector having at least one fluid passage and a second connector having at least one fluid passage that is initially in a closed position. The first connector includes a key portion that may be inserted in the second connector to actuate the second connector and move the second connector to an open position, such that the first connector may be joined with the second connector, and the fluid passages may be in fluid communication with one another. In the exemplary embodiments described herein, the first connector may be a male connector and the second connector may be a female connector and the male connector may be inserted into the female connector, or the fluid connection device may be configured such that the first connector may be a female connector and the second connector may be a male connector, or the connectors otherwise may be joined together with the key portion being located on one of the connectors and being configured to actuate the other of the connectors when the connectors are joined together.

The key 134 may be inserted into the key-receiving aperture 162 to open the flap door 152. Inserting the key 134 in the key-receiving aperture 162 may activate a spring-loaded opening mechanism 155. The spring-loaded opening mechanism 155 may be fixedly positioned within the housing 142 and outside the receiving chamber 148. The spring-loaded opening mechanism 155 may be positioned at a location behind the opening 150 and below the receiving chamber 148. The spring-loaded opening mechanism 155 may normally engage the flap door 152 to bias the flap door 152 in the closed position. When the spring-loaded opening mechanism 155 is activated by the key 134, the force against the flap door 152 may overcome the spring force of the spring-loaded opening mechanism 155, allowing the spring-loaded opening mechanism 155 to be moved by the flap door 152 such that the flap door 152 moves to the open position. The spring-loaded opening mechanism 155 may include any suitable type of spring, such as a flat spring or a metal clip. The closed position may be defined by the flap door 152 being perpendicularly arranged relative to the longitudinal axis of the chamber 148. The open position may be defined by the flap door 152 pivoting approximately 90 degrees to a position perpendicular to the closed position and parallel to the longitudinal axis, such that the male connector 122 may be inserted into the receiving chamber 148 through the opening 150.
The male connector 122 may further include a locking mechanism 136, which may be in the form of locking bumps positioned on an exterior surface of the body 126. Bumps are an example and any suitable locking mechanism may be used. When the male connector 122 has been fully inserted within the receiving chamber 148 of the female connector 124, the male connector 122 may be further rotated until the locking bumps 136 engage with a corresponding female locking mechanism 168 to lock the male connector 120 and the female connector 124 together. The female locking mechanism 168 may be in the form of ridges that engage within the locking bumps 136. When the locking features are engaged, further axial movement or rotation of the male connector 122 is prevented relative to the female connector 124. Rotation of the male connector 122 may also compress a sealing member 138 located along the longitudinal axis within the receiving chamber 148 of the female connector 124. A plurality of sealing members may be provided and the sealing member 138 may be in the form of any suitable seal, such as a gasket. Compressing the sealing member 138 enables the fluid passages of the male connector 122 and the female connector 124 to be in sealed fluid communication.
