Abstract

The present invention generally relates to receiving bodily fluid through a device opening. In one aspect, the device includes a flow activator arranged to cause fluid to be released from a subject. A deployment actuator may actuate the flow activator in a deployment direction, which may in turn cause fluid release from a subject. The flow activator may also be moved in a retraction direction by a retraction actuator. In one aspect, the device may include a vacuum source that may help facilitate fluid flow into the opening of the device and/or may help facilitate fluid flow from the opening to a storage chamber. In one aspect, a device actuator may enable fluid communication between the opening and the vacuum source and the flow activator may be actuated after the enablement of fluid communication.

Claims

1. A device for receiving fluid from a subject, comprising:

a housing including an opening to receive fluid into the housing;

one or more needles being arranged to cause fluid to be released from the subject;

a device actuator to cause the one or more needles to move relative to the housing in a deployment direction to cause the fluid to be released from the subject;

a retraction actuator to move the one or more needles relative to the housing in a retraction direction away from the opening; and

a rotatable element that prohibits the retraction actuator from moving the one or more needles relative to the housing in the retraction direction prior to actuation of the device actuator and rotates relative to the housing to permit the retraction actuator to move the one or more needles in the retraction direction,

wherein at least a portion of the retraction actuator and at least a portion of the rotatable element are located within the housing.

2. The device of claim 1, wherein:

the retraction actuator moves the rotatable element in the retraction direction, and

the rotatable element rotates relative to the housing as the rotatable element moves in the retraction direction.

3. The device of claim 2, wherein the housing includes a ramp, and movement of the retraction actuator in the retraction direction causes a portion of the rotatable element to slide against the ramp, which causes the rotatable element to rotate relative to the housing as the rotatable element moves in the retraction direction.

4. The device of claim 3, wherein the portion of the rotatable element comprises a second ramp.

5. The device of claim 1, further comprising a pre-deployment lockout, wherein engagement of the rotatable element with the pre-deployment lockout prevents the retraction actuator from moving the one or more needles and the rotatable element in the retraction direction.

6. The device of claim 5, wherein actuation of the device actuator causes the rotatable element to disengage from the pre-deployment lockout to permit the retraction actuator to move the one or more needles and the rotatable element in the retraction direction.

7. The device of claim 6, wherein disengagement of the rotatable element from the pre-deployment lockout permits the retraction actuator to move in the retraction direction by releasing stored potential energy.

8. The device of claim 7, wherein engagement of the rotatable element with the pre-deployment lockout locks the retraction actuator in a high-energy state.

9. The device of claim 7, wherein the retraction actuator comprises a spring.

10. The device of claim 9, wherein the retraction actuator comprises a leaf spring.

11. The device of claim 5, wherein the pre-deployment lockout comprises an indentation shaped to receive a portion of the rotatable element.

12. The device of claim 1, further comprising a deployment actuator to move the one or more needles and the rotatable element in a deployment direction toward or through the opening.

13. The device of claim 12, further comprising a pre-deployment lockout, wherein actuation of the device actuator actuates the deployment actuator to move the one or more needles and the rotatable element in the deployment direction and causes the rotatable element to disengage from the pre-deployment lockout to permit the retraction actuator to move the one or more needles and the rotatable element in the retraction direction.

14. The device of claim 1, further comprising a post-deployment lockout, wherein engagement of the rotatable element with the post-deployment lockout locks the device in a retracted state.

15. The device of claim 1, further comprising a vacuum chamber in the housing that is at a pressure less than ambient pressure prior to actuation of the device actuator.

16. The device of claim 15, wherein the housing includes a cover and a base, and wherein the vacuum chamber is bounded by the cover and the base.

17. The device of claim 15, further comprising a flow control element to control flow in a flow path between the opening and the vacuum chamber, wherein actuation of the device actuator causes the flow control element to enable fluid communication between the opening and the vacuum chamber.

18. The device of claim 17, wherein the flow control element comprises a seal.

19. The device of claim 18, further comprising a piercing member enclosed by the housing, wherein actuation of the device actuator causes the piercing member to pierce the seal.

20. A device for receiving fluid from a subject, comprising:

a housing including an opening to receive fluid into the housing;

a vacuum chamber in the housing that is at a pressure less than ambient pressure prior to actuation of the device actuator;

one or more needles being arranged to cause fluid to be released from the subject;

a device actuator to cause the one or more needles to move relative to the housing in a deployment direction to cause the fluid to be released from the subject;

a retraction actuator to move the one or more needles in a retraction direction away from the opening; and

a rotatable element that prohibits the retraction actuator from moving the one or more needles in the retraction direction prior to actuation of the device actuator and rotates relative to the housing to permit the retraction actuator to move the one or more needles in the retraction direction,

wherein at least a portion of the retraction actuator and at least a portion of the rotatable element are located within the housing.
