AI Technical Summary
Unexpected dislocation or disconnection of medical connectors can lead to patient injury and exposure of healthcare professionals to harmful drugs, increasing the risk of infection. Existing technologies are insufficient to effectively prevent such incidents.
A fluid connector assembly is designed in which each medical connector automatically separates in response to external forces, including bellows or other elastic compressible elements, to ensure a seal is restored after the external force is removed. A connection mechanism is provided for reconnection after separation. The automatic separation and reconnection of the connector assembly in the external environment is achieved by designing the engagement of protrusions and grooves.
It limits or prevents patient blood loss, IV fluid loss, infection, and medical delivery delays, and enables the automatic separation and reconnection of the fluid connector assembly to prevent patient blood loss, IV fluid loss, infection, and medical delivery delays.

Abstract
Claims
1. A fluid connector assembly comprising: Comprising: a first connector having a first housing, a second connector configured to couple with the first connector, the second connector having a second housing, a connection mechanism disposed on at least one of the first connector and the second connector for removably coupling the first connector and the second connector, wherein the connection mechanism disengages when a predetermined pulling force is applied to at least one of the first connector and the second connector, thereby allowing the first connector and the second connector to separate, and wherein an inner surface of one of the first connector is exposed when the first connector and the second connector separate, thereby allowing sterilization.
2. The fluid connector assembly of claim 1, wherein, The connection mechanism includes a first connection member coupled to one of the first connector or the second connector.
3. The fluid connector assembly of claim 2, wherein, The first connection member includes a protruding member disposed at a first end of the first connection member.
4. The fluid connector assembly of claim 3, wherein, A second connection member is also included, and wherein the first connection member is coupled to the first connector and the second connection member is coupled to the second connector.
5. The fluid connector assembly of claim 4, wherein, The second connection member includes a groove for receiving the protruding member, wherein the first connection member and the second connection member couple such that the protruding member is received within the groove when the first connector and the second connector are coupled, and wherein the first connection member and the second connection member disengage when a predetermined force is applied.
6. The fluid connector assembly of claim 4, wherein, The first connection member is a compression ring, and wherein the first connection member is flexible.
7. The fluid connector assembly of claim 6, wherein, The second connection member also includes a groove for receiving a protruding member of the compression ring.
8. The fluid connector assembly of claim 4, wherein, The first connection member and the second connection member couple when the first connector and the second connector are coupled, and wherein the first connection member and the second connection member disengage when a predetermined force is applied.
9. The fluid connector assembly of claim 3, wherein, The protruding member is configured to engage an elastomeric ring, and wherein the protruding member disengages the elastomeric ring when a predetermined force is applied, thereby causing the first connector and the second connector to separate.
10. The fluid connector assembly of claim 2, wherein, The first connection member includes an elastic band and one or more engagement portions disposed about the first connector or second connector, and wherein the elastic band is disposed about the one or more engagement portions.
11. The fluid connector assembly of claim 10, wherein, The elastic band is configured to deflect until a predetermined threshold force is applied, and wherein the elastic band expands when the predetermined threshold force is applied, allowing the one or more engagement portions to pull, thereby causing the first connector and the second connector to separate.
12. A fluid connector assembly comprising: Comprising: a first connector having a first housing; a second connector configured to couple with the first connector, the second connector having a second housing; a connection mechanism disposed on at least one of the first connector and the second connector for removably coupling the first connector and the second connector, and wherein the first connector and the second connector separate when a predetermined threshold pulling force is applied to one of the first connector and the second connector.
13. The fluid connector assembly of claim 12, wherein, The connection mechanism includes a first connection member coupled to one of the first connector or the second connector.
14. The fluid connector assembly of claim 13, wherein, The first connection member includes a protrusion member disposed at a first end of the first connection member.
15. The fluid connector assembly of claim 14, wherein, A second connection member is also included, and The first connection member is coupled to the first connector, and the second connection member is coupled to the second connector.
16. The fluid connector assembly of claim 15, wherein, The second connection member includes a groove for receiving the protrusion member, The first connection member and the second connection member are coupled such that the protrusion member is received within the groove when the first connector and the second connector are coupled, and The first connection member and the second connection member are decoupled when a predetermined force is applied.
17. The fluid connector assembly of claim 15, wherein, The first connection member is a compression ring, and The first connection member is flexible.
18. The fluid connector assembly of claim 17, wherein, The second connection member also includes a groove for receiving a protrusion member of the compression ring.
19. The fluid connector assembly of claim 15, wherein, The first connection member and the second connection member are coupled when the first connector and the second connector are coupled, and The first connection member and the second connection member are decoupled when a predetermined force is applied.
20. The fluid connector assembly of claim 14, wherein, The protrusion member is configured to engage an elastomeric ring, and The protrusion member disengages the elastomeric ring when a predetermined force is applied, thereby decoupling the first connector and the second connector.
