## Abstract

An apparatus includes a housing defining an inner volume, a distal coupler at least temporarily coupled to a distal end portion of the housing and configured to be placed in fluid communication with a bodily fluid source, a fluid communicator disposed in the inner volume, and a lock coupled to the housing. The lock is transitionable between a first configuration in which the lock couples the distal coupler to housing such that a portion of the fluid communicator extends through a seal of the distal coupler to place the distal coupler in fluid communication with a proximal end portion of the housing and a second configuration in which the lock allows for removal of the distal coupler. The lock is configured to be transitioned back to the first configuration after removing the distal coupler to limit access to the fluid communicator via the distal end portion of the housing.

The apparatus of claim 1, wherein the lock includes a stage that is in at least temporarily maintained in a first position when the lock is in the first configuration and allowed to be moved to a second position when the lock is in the second configuration, the stage limiting access to the fluid communicator when in the first position.

### Claim 3 (depends on 2)

The apparatus of claim 2, wherein the lock is configured to be transitioned from the second configuration to the first configuration after removing the distal coupler from the housing to prevent the stage from being moved from the first position toward the second position.

### Claim 4 (depends on 3)

The apparatus of claim 3, wherein the fluid communicator is a needle having a sharpened distal end portion, the stage configured to limit access to the sharpened distal end portion of the needle when in the first position.

### Claim 5 (depends on 1)

The apparatus of claim 1, further comprising:
a proximal coupler coupled to the proximal end portion of the housing and fluidically coupled to the fluid communicator, the proximal coupler configured to couple to a fluid collection device, the fluid collection device configured to receive a volume of bodily fluid via the fluid communicator when the lock is in the first configuration.

### Claim 6 (depends on 5)

The apparatus of claim 5, wherein the distal end portion of the housing is configured to receive a portion of a sample reservoir when the lock is in the second configuration and the distal coupler is removed from the housing, the fluid communicator configured to extend into the sample reservoir when the portion of the sample reservoir is disposed in the housing to allow at least a portion of the volume of bodily fluid to be transferred from the fluid collection device to the sample reservoir via the fluid communicator.

### Claim 7

An apparatus, comprising:
a housing having a proximal end portion and a distal end portion and defining an inner volume, the proximal end portion having a proximal coupler;
a fluid communicator disposed in the inner volume of the housing and fluidically coupled to the proximal coupler;
a stage disposed in the housing and movable between a first position and a second position; and
a bias member disposed in the housing and in contact with a proximal side of the stage, the bias member configured to bias the stage in the first position such that the stage substantially prevents access to the fluid communicator via the distal end portion of the housing, the bias member allowing the stage to be moved to the second position in response to a force exerted on a distal side of the stage such that a portion of the fluid communicator extends through the stage, thereby allowing access to the fluid communicator via the distal end portion of the housing.

### Claim 8 (depends on 7)
