Abstract
A system for analyzing a physiological sample includes a cartridge configured to attach to the skin of a subject. The cartridge includes: a processing fluid pack that is configured to release a processing fluid stored therein, a diagnostic test strip, and a vacuum pin. The system also includes a lancet with a needle. The lancet is configured to deploy the needle upon engagement with the cartridge to draw a physiological sample from the subject. The vacuum pin is configured to create a vacuum within the cartridge to draw the released processing fluid and the drawn physiological sample to the diagnostic test strip.
Core Innovation
Dermal patch system for analyzing a physiological sample includes a cartridge configured to attach to the skin of a subject. The cartridge includes a processing fluid pack configured to release a processing fluid, a diagnostic test strip, and a vacuum pin, arranged within the cartridge for sample processing and delivery to the diagnostic test strip.
A lancet with a needle is provided so that, upon engagement of the lancet with the cartridge, the lancet automatically deploys the needle to draw a physiological sample from the subject. A vacuum pin is configured to create a vacuum within the cartridge to draw both the released processing fluid and the drawn physiological sample to the diagnostic test strip.
The description further includes cartridge/lancet mechanics and diagnostic result handling, including engagement-driven needle states and a vacuum pin deployment sequence that forms internal vacuum and sample/vacuum channels. The diagnostic workflow includes viewing indicators on the test strip and an imaging-based process in which scanned images or photographs are used to determine a test result, with optional association to an electronic medical record using a quick response code and updating the record with the determined result.
Claims Coverage
The partial content identifies two independent claims, both centered on a skin-attachable cartridge system with an automatically deployed lancet and a vacuum pin that uses negative pressure to draw both released processing fluid and the drawn physiological sample to a diagnostic test strip. No other independent claims are provided in the supplied claim list.
Skin-attached cartridge with processing fluid pack, diagnostic test strip, and vacuum pin
The system comprises a cartridge configured to attach to the skin of a subject, wherein the cartridge includes a processing fluid pack configured to release a processing fluid stored therein, a diagnostic test strip, and a vacuum pin.
Automatically deployed lancet for drawing physiological sample
A lancet with a needle is configured to automatically deploy the needle upon engagement of the lancet with the cartridge to draw a physiological sample from the subject.
Vacuum pin creates vacuum to draw released processing fluid and physiological sample to the test strip
The vacuum pin is configured to create a vacuum within the cartridge to draw the released processing fluid and the drawn physiological sample to the diagnostic test strip.
Cartridge configured to attach to skin with integrated vacuum-driven sampling
A cartridge configured to attach to the skin of a subject comprising a processing fluid pack configured to release a processing fluid stored therein, a diagnostic test strip, and a vacuum pin, and including a lancet with a needle configured to automatically deploy the needle upon engagement to draw a physiological sample, wherein the vacuum pin is configured to create a vacuum within the cartridge to draw the released processing fluid and the drawn physiological sample to the diagnostic test strip.
Across the two independent claims, the core claim coverage is the same: a skin-attachable cartridge integrates a processing fluid pack, a diagnostic test strip, and a vacuum pin, and a lancet that automatically deploys to draw a physiological sample, with vacuum-driven drawing of both released processing fluid and drawn sample to the diagnostic test strip.
