Syringe adapter with lock mechanism

1. A syringe adapter comprising:

a housing having a first end and a second end, the first end configured to be secured to a first container;

a cannula having a first end and a second end, the second end of the cannula positioned within the housing; and

a seal arrangement positioned within the housing, the seal arrangement movable within the housing between a first position where the seal arrangement is disengaged from a mating connector and a second position where the seal arrangement is engaged with a mating connector, the seal arrangement comprising a membrane; and

a lock mechanism movable between an unlocked position and a locked position,

wherein the seal arrangement includes a lock interface that is configured to engage the lock mechanism when the seal arrangement is in the second position and when the lock mechanism is in the locked position,

wherein the lock mechanism is disengaged from the lock interface when the seal arrangement is in the second position and when the lock mechanism is in the unlocked position, wherein the lock mechanism has a first end and a second end,

wherein, when the lock mechanism is in the unlocked position, the first end of the lock mechanism protrudes from the housing and the second end of the lock mechanism is received within the housing, and wherein, when the lock mechanism is in the locked position, the first end of the lock mechanism is received within the housing and the second end of the lock mechanism protrudes from the housing, the lock mechanism is manually movable from the unlocked position to the locked position and manually movable from the locked position to the unlocked position.

2. The syringe adapter of claim 1 , wherein the second end of the lock mechanism includes an indicator.

3. The syringe adapter of claim 1 , wherein the first end of the lock mechanism comprises a first color and the second end of the lock mechanism comprises a second color, the first color different than the second color.

4. The syringe adapter of claim 1 , wherein the seal arrangement comprises a collet having a first end and a second end, at least a portion of the collet received within the housing, the collet comprising a body and a locking member connected to the body, the body defining a passageway that receives the membrane of the seal arrangement, the collet is movable from a first position where the locking member is open to receive a mating connector to a second position where radially outward movement of the locking member is restricted.

5. The syringe adapter of claim 4 , wherein the lock mechanism defines an opening configured to receive the collet.

6. The syringe adapter of claim 5 , wherein the lock mechanism is received within a transverse opening of the housing, the lock mechanism retained within the housing via retention portions of the lock mechanism positioned intermediate the first and second ends of the lock mechanism that engage the housing.

7. A system for closed transfer of fluids comprising:

a syringe adapter comprising:

a housing having a first end and a second end, the first end configured to be secured to a first container;

a cannula having a first end and second end, the second end of the cannula positioned within the housing; and

a seal arrangement positioned within the housing, the seal arrangement movable within the housing and comprising a membrane; and

a lock mechanism moveable between an unlocked position and a locked position,

a second component comprising a membrane configured to engage the membrane of the seal arrangement to move the seal arrangement between a first position where the seal arrangement is disengaged from the second component and a second position where the seal arrangement is engaged with the second component,

wherein the seal arrangement includes a lock interface that is configured to engage the lock mechanism when the seal arrangement is in the second position and when the lock mechanism is in the locked position,

wherein the lock mechanism is disengaged from the lock interface when the seal arrangement is in the second position and when the lock mechanism is in the unlocked position, wherein the lock mechanism has a first end and a second end, and

wherein, when the lock mechanism is in the unlocked position, the first end of the lock mechanism protrudes from the housing and the second end of the lock mechanism is received within the housing, wherein, when the lock mechanism is in the locked position, the first end of the lock mechanism is received within the housing and the second end of the lock mechanism protrudes from the housing, the lock mechanism is manually movable from the unlocked position to the locked position and manually movable from the locked position to the unlocked position, and wherein the first end of the lock mechanism comprises a first color and the second end of the lock mechanism comprises a second color, the first color different than the second color.

8. The system of claim 7 , wherein the seal arrangement comprises a collet having a first end and a second end, at least a portion of the collet received within the housing, the collet comprising a body and a locking member connected to the body, the body defining a passageway that receives the membrane of the seal arrangement, the collet is movable from a first position where the locking member is open to receive the second component to a second position where radially outward movement of the locking member is restricted.

9. The system of claim 8 , wherein the lock mechanism defines an opening configured to receive the collet.

10. The system of claim 9 , wherein the lock mechanism is received within a transverse opening of the housing, the lock mechanism retained within the housing via retention portions of the lock mechanism positioned intermediate the first and second ends of the lock mechanism that engage the housing.
