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 rotatable element that actuates the deployment actuator.
Claims58
A device for receiving fluid from a subject, comprising:
- a housing including an opening to receive fluid into the housing;
- a device actuator;
- one or more needles being arranged to cause fluid to be released from the subject,
- a deployment actuator that moves the one or more needles in a deployment direction toward a subject;
- and
- a rotatable element that contacts the deployment actuator to actuate the deployment actuator after actuation of the device actuator, the rotatable element being rotatable relative to the housing,
- wherein actuation of the device actuator causes the rotatable element to rotate and move toward the deployment actuator.
A device for receiving fluid from a subject, comprising:
- a housing comprising a base;
- a deployment actuator;
- a carrier coupled to the deployment actuator;
- a deployment actuator initiating element that actuates the deployment actuator by contacting and exerting a force on the deployment actuator, the initiating element having at least one spring member and the initiating element being positioned on the carrier;
- a retraction actuator positioned between the carrier and the base such that movement of the carrier towards the base causes the retraction actuator to compress;
- wherein a stiffness of the at least one spring member is greater than a stiffness of the retraction actuator.
A device for receiving fluid from a subject, the device comprising:
- a housing comprising a base, the base including a hole and a device opening, the hole being spaced from the device opening;
- a deployment actuator;
- a flow activator comprising a plurality of needles;
- and
- an intermediate component coupling the flow activator to the deployment actuator, the intermediate component extending across the hole and being movable through the hole,
- wherein, when the intermediate component is in the retracted position, the intermediate component seals the hole such that fluid communication through the hole is closed.
A device for receiving fluid from a subject, comprising:
- a housing comprising a base;
- a deployment actuator that moves the one or more needles in a deployment direction toward a subject;
- and
- a carrier coupled to the deployment actuator, wherein upon actuation, the carrier moves toward the device opening prior to actuation of the deployment actuator.
A device for receiving fluid from a subject, comprising:
- a housing comprising a base;
- a deployment actuator;
- a carrier coupled to the deployment actuator;
- a deployment actuator initiating element that actuates the deployment actuator by contacting and exerting a force on the deployment actuator, the initiating element having at least one spring member and the initiating element being positioned on the carrier,
- wherein the at least one spring member contacts the carrier prior to the initiating element contacting the deployment actuator.
A device for receiving fluid from a subject, comprising:
- a housing including an opening to receive fluid into the housing, the housing comprising a base;
- a device actuator;
- one or more needles being arranged to cause fluid to be released from the subject;
- an anticoagulant coating on the base;
- a covering element positioned on the anticoagulant coating, the covering element having spaces that expose the anticoagulant coating.
