Abstract

An apparatus includes a housing that defines a fluid reservoir and includes a port that is in fluid communication with the fluid reservoir. An inlet adapter is removably coupleable to the housing. A user can engage an actuator to move a plunger from a first position in which the fluid reservoir has a first volume, to a second position in which the fluid reservoir has a second volume greater than the first volume, which draws bodily fluid into the fluid reservoir via the inlet adapter. The actuator modulates a plunger rate of motion below a threshold as the plunger is moved. When a predetermined volume of bodily fluid is transferred into the fluid reservoir, a volume indicator transitions from a first state to a second state and the inlet adapter can then be removed to transfer the predetermined volume into a sample bottle external to the housing via the port.

First claim

What is claimed:

1 . An apparatus, comprising:
a housing defining a fluid reservoir and including a port in fluid communication with the fluid reservoir; an inlet adapter removably coupleable to the housing, the inlet adapter including a needle configured to place the port in fluid communication with a bodily fluid source when the inlet adapter is coupled to the housing; an actuator including a plunger at least partially disposed within the housing and defining at least a part of the fluid reservoir, a first portion of the actuator configured to be engaged by a user to move the plunger within the housing from a first position in which the fluid reservoir has a first volume, to a second position in which the fluid reservoir has a second volume greater than the first volume, the increase in volume operable to draw bodily fluid into the fluid reservoir via the inlet adapter; and a volume indicator coupled to the housing and configured to transition from a first state in which an arm of the volume indicator is in a first position relative to the housing to a second state in which the arm of the volume indicator is in a second position relative to the housing, the volume indicator being in the second state in response to a predetermined volume of bodily fluid being transferred into the fluid reservoir, the predetermined volume being less than the second volume of the fluid reservoir, the volume indicator in the second state configured to be brought into contact with a portion of the actuator to at least temporarily stop the plunger from being moved proximally toward the second position.

2 . The apparatus of claim 1 , wherein the volume indicator in the second state is configured to provide an indication to the user associated with the predetermined volume of bodily fluid being transferred into the fluid reservoir.

3 . The apparatus of claim 1 , wherein the arm of the volume indicator is configured to rotate between the first position and the second position.

4 . The apparatus of claim 1 , wherein after the predetermined volume of bodily fluid is transferred into the fluid reservoir, the volume indicator is configured to transition to a third state in which the plunger is allowed to be moved to the second position.

5 . The apparatus of claim 1 , wherein the first portion of the actuator is moved through a first range of motion when engaged by the user, the actuator configured to move the plunger through a second range of motion different from the first range of motion.

6 . The apparatus of claim 1 , wherein the actuator is configured to modulate a rate of motion of the plunger below a threshold as the plunger is moved from the first position to the second position.

7 . The apparatus of claim 1 , wherein the inlet adapter is configured to be removed from the housing after the predetermined volume of bodily fluid is transferred into the fluid reservoir to allow transfer of the predetermined volume to a sample bottle external to the housing via the port.

8 . An apparatus, comprising:
a housing defining a fluid reservoir and including a port in fluid communication with the fluid reservoir; an inlet adapter removably coupleable to the housing, the inlet adapter including a needle configured to place the port in fluid communication with a bodily fluid source when coupled to the housing; an actuator including a plunger at least partially disposed within the housing and defining at least a part of the fluid reservoir, the actuator configured to move the plunger within the housing between a first position and a second position, the fluid reservoir having a first volume when the plunger is in the first position and a second volume greater than the first volume when the plunger is in the second position, an increase in a volume of the fluid reservoir operable to draw bodily fluid into the fluid reservoir via the inlet adapter, a volume indicator including an arm configured to transition from a first configuration to a second configuration in response to a portion of the actuator engaging the volume indicator as the actuator moves the plunger from the first position toward the second position, the arm being in the second configuration in response to a predetermined volume of bodily fluid being transferred into the fluid reservoir, the predetermined volume being less than the second volume, the arm in the second configuration is configured to be brought into contact with the portion of the actuator to at least temporarily stop the actuator from further moving the plunger proximally to place the plunger in the second position.

9 . The apparatus of claim 8 , wherein the arm in the second configuration is configured to provide an indication to a user associated with the predetermined volume of bodily fluid being transferred into the fluid reservoir.

10 . The apparatus of claim 8 , wherein after the predetermined volume of bodily fluid is transferred into the fluid reservoir, the volume indicator is configured to transition to a third configuration in which the plunger is allowed to be move to the second position.

11 . The apparatus of claim 8 , wherein the actuator is moved through a first range of motion when engaged by a user, the actuator configured to move the plunger through a second range of motion different from the first range of motion.

12 . The apparatus of claim 8 , wherein the actuator is configured to modulate a rate of motion of the plunger below a threshold as the plunger is moved from the first position to the second position.

13 . The apparatus of claim 8 , wherein the inlet adapter is configured to be removed from the housing after the predetermined volume of bodily fluid is transferred into the fluid reservoir to allow transfer of the predetermined volume to a sample bottle external to the housing via the port.

14 . An apparatus, comprising:
a housing defining a fluid reservoir and including a port in fluid communication with the fluid reservoir, an inlet adapter removably coupleable to the housing, the inlet adapter including a needle configured to place the port in fluid communication with a bodily fluid source when coupled to the housing; an actuator including a plunger at least partially disposed within the housing and defining at least a part of the fluid reservoir, the actuator configured to move the plunger within the housing between a first position and a second position, the fluid reservoir having a first volume when the plunger is in the first position and a second volume greater than the first volume when the plunger is in the second position, an increase in a volume of the fluid reservoir operable to draw bodily fluid into the fluid reservoir via the inlet adapter, a volume indicator including an arm, the arm separate from the actuator and configured to move through a portion of the housing as the actuator moves the plunger proximally from the first position toward the second position, the arm configured to move relative to the actuator as the volume indicator transitions from a first configuration to a second configuration, the volume indicator in the second configuration configured such that the arm indicates transfer of a predetermined volume of bodily fluid into the fluid reservoir.

15 . The apparatus of claim 14 , wherein a portion of the volume indicator is configured to at least temporarily stop the plunger from moving further toward the second position when the volume indicator is in the second configuration.

16 . The apparatus of claim 14 , wherein after the predetermined volume of bodily fluid is transferred into the fluid reservoir, the volume indi
