Abstract
A device for collecting a physiological sample from a subject includes a lancet with a needle that is configured to puncture the subject's skin and a cartridge configured to engage with the lancet. The lancet is configured to transition the needle from an undeployed position to a deployed position in response to engagement with the cartridge, thereby allowing the needle to puncture the subject's skin.
Claims17
A device for collecting a physiological sample from a subject, comprising:
- a lancet having a needle configured to puncture the subject's skin, and
- a cartridge configured to engage with the lancet,
- wherein the lancet is configured to automatically transition the needle from an undeployed position to a deployed position in response to a force applied to the lancet by engagement of the lancet with the cartridge, thereby allowing the needle to puncture the subject's skin.
A method for obtaining a physiological sample, comprising:
- attaching a cartridge of a dermal patch system onto skin of a subject,
- coupling a lancet with a needle to the cartridge,
- wherein coupling the lancet to the cartridge applies a force to the lancet that causes the needle to automatically draw the physiological sample.
A lancet for use with a cartridge of a dermal patch system, comprising:
- a housing configured for engagement with the cartridge,
- a needle disposed within the housing, and
- a mechanism configured to retain the needle within the housing in absence of engagement of the lancet with the cartridge and to automatically deploy the needle for puncturing skin in response to a force applied to the lancet by engagement of the lancet with the cartridge.
