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, the port including a puncture member;
an inlet adapter removably coupleable to the housing, the inlet adapter having a pierceable portion configured to be pierced by the puncture member to place placing the port in fluid communication with a bodily fluid source when the inlet adapter is coupled to the housing;
an actuator including a plunger disposed within and defining at least a part of the fluid reservoir, a 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, the actuator modulating a rate of motion of the plunger below a threshold as the plunger is moved from the first position to the second position; and
a volume indicator configured to transition from a first state to a second state in response to a predetermined volume of bodily fluid being disposed in the fluid reservoir,
the inlet adapter 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.

2. The apparatus of claim 1 , wherein the predetermined volume is less than the second volume.

3. The apparatus of claim 2 , wherein the volume indicator is configured to at least temporarily stop the plunger from being moved toward the second position when in the second state.

4. The apparatus of claim 1 , wherein the predetermined volume is equal to the second volume.

5. The apparatus of claim 1 , wherein the predetermined volume is between about 10 milliliters (mL) and about 30 mL.

6. The apparatus of claim 1 , wherein the predetermined volume is 10 mL.

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

8. The apparatus of claim 1 , wherein modulating the rate of motion of the plunger below the threshold reduces a flow rate of bodily fluid into the fluid reservoir thereby increasing an accuracy associated with the predetermined volume of bodily fluid being transferred into the fluid reservoir.

9. The apparatus of claim 1 , wherein the predetermined volume of bodily fluid is a first predetermined volume of bodily fluid, the volume indicator is configured to transition to a third state in response to a second predetermined volume of bodily fluid being transferred into the fluid reservoir, the second predetermined volume being greater than the first predetermined volume.

10. An apparatus, comprising:
a housing defining a fluid reservoir and including a port in fluid communication with the fluid reservoir, the port including a puncture member;
an inlet adapter removably coupleable to the housing, the inlet adapter having a pierceable portion configured to be pierced by the puncture member to place placing the port in fluid communication with a bodily fluid source when the inlet adapter is coupled to the housing;
an actuator including a plunger disposed within 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, the actuator configured to modulateing a rate of motion of the plunger below a threshold as the plunger is moved from the first position to the second position; and
a volume indicator configured to transition from a first state to a second state associated with 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 configured to at least temporarily stop the plunger from being moved toward the second position when in the second state
the inlet adapter 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.

11. The apparatus of claim 10 , wherein a portion of the actuator is moved through a first range of motion when engaged by a user, the plunger configured to be moved through a second range of motion different from the first range of motion.

12. The apparatus of claim 10 , wherein the bodily fluid is blood, the sample bottle is a blood culture bottle including an anaerobic culture medium, and the predetermined volume of bodily fluid is a volume of blood associated with anaerobic blood culture testing.

13. The apparatus of claim 10 , wherein the bodily fluid is blood, the sample bottle is a blood culture bottle including an aerobic culture medium, and the predetermined volume of bodily fluid is a volume of blood associated with aerobic blood culture testing.

14. The apparatus of claim 10 , wherein the predetermined volume is between about 10 milliliters (mL) and about 30 mL.

15. The apparatus of claim 10 , 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 placed in the second position.

16. The apparatus of claim 15 , wherein the predetermined volume of bodily fluid is a first predetermined volume of bodily fluid, the second volume of the fluid reservoir when the plunger is in the second position is a second predetermined volume greater than the first predetermined volume.

17. A method, comprising:
placing an inlet adapter of a fluid transfer device in fluid communication with a bodily fluid source, the inlet adapter being removably coupleable to a housing of the fluid transfer device such that a port fluidically couples the inlet adapter to a fluid reservoir defined by the housing, the port including a puncture member configured to pierce a pierceable portion of the inlet adapter to place the port in fluid communication with a bodily fluid source;
engaging an actuator to move a plunger disposed within and defining at least a part of the fluid reservoir from a first position toward a second position, the movement of the plunger producing a negative pressure operable to draw bodily fluid into the fluid reservoir via the inlet adapter,
modulating a rate of motion of the plunger below a threshold as the actuator moves the plunger is from the first position to the second position;
transitioning a volume indicator from a first state to a second state when a predetermined volume of bodily fluid is transferred into the fluid reservoir;
removing the inlet adapter from the housing after the predetermined volume of bodily fluid is transferred into the fluid reservoir; and
transferring the predetermined volume of bodily fluid from the fluid reservoir to a sample bottle external to the fluid transfer device via the port.
