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.
Core Innovation
The invention relates to a device for collecting a physiological sample from a subject. The device includes a lancet having a needle configured to puncture the subject's skin, and a cartridge configured to engage with the lancet. In response to engagement with the cartridge, the lancet automatically transitions the needle from an undeployed position to a deployed position, thereby allowing the needle to puncture the subject's skin.
The device further includes a specimen collection pad housing with a specimen collection pad disposed therein, a physiological sample well, and a physiological sample channel in open communication with the physiological sample well and the specimen collection pad housing. A lancet aperture is in open communication with the physiological sample well, and the lancet aperture and the physiological sample well are configured to allow the needle to extend therethrough to puncture the skin of the subject when the device is affixed to the subject's skin.
Additional configurations described include an adhesive layer on the cartridge with the specimen collection pad attached to the adhesive layer, a removable specimen collection pad, and a removable cover. Viewing apertures and transparent windows are described as allowing visual access to the specimen collection pad inside the housing, and structural configurations of the physiological sample channel include a three-sided channel portion.
Claims Coverage
The independent claim covers a dermal patch system for collecting a physiological sample using a lancet that automatically transitions the needle from an undeployed position to a deployed position when engaged with a cartridge, in combination with a specimen collection pad housing, a physiological sample well and channel, and a lancet aperture that enables the needle to extend through to the physiological sample well when affixed to the subject's skin. Dependent claims further refine how the specimen collection pad and cover are implemented and how viewing access and channel geometry are provided.
Automatically transitioned lancet needle via cartridge engagement
A cartridge configured to engage with the lancet, wherein the lancet automatically transitions 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.
Physiological sample well and open-communication physiological sample channel to specimen pad housing
A specimen collection pad housing with a specimen collection pad disposed therein, a physiological sample well, and a physiological sample channel in open communication with the physiological sample well and the specimen collection pad housing.
Lancet aperture enabling needle extension through physiological sample well to puncture skin when affixed
A lancet aperture in open communication with the physiological sample well, wherein the lancet aperture and the physiological sample well are configured to allow the needle to extend therethrough to puncture the skin of the subject when the device is affixed to the subject's skin.
Removable specimen collection pad attached via adhesive layer
An adhesive layer on the cartridge, with the specimen collection pad attached to that adhesive layer, and wherein the specimen collection pad is removable.
Three-sided physiological sample channel portion
The device is configured so that at least part of the physiological sample channel has a three-sided shape.
Removable cover with viewing apertures for visual access
A removable cover, and viewing apertures in both the cover and the specimen collection pad housing that allow visual access to the specimen collection pad inside the housing.
Overall, the claim coverage centers on automatic lancet needle deployment triggered by cartridge engagement, combined with a physiological sample well/channel arrangement that is in open communication with a specimen collection pad housed within a housing and accessed through a lancet aperture. Dependent refinements add removability and attachment of the specimen collection pad, possible three-sided channel geometry, and viewing apertures provided via a removable cover and the pad housing.
