Blood sugar level measuring method and apparatus

In a method and apparatus for determining the blood glucose concentration reliably and accurately based on temperature data obtained from a subject without requiring blood sampling, chronological changes in the output from a temperature detecting portion are monitored. Based on those chronological changes, the making of contact between a body surface and a body surface contact portion is detected, whereupon the acquisition of measurement data is started and an advance-notice display about the timing of departure of the body surface is made. The moment of departure of the body surface from the body surface contact portion is detected, and if that moment is before the noticed timing, or in the absence of detection of the departure of the body surface from the body surface contact portion even after a certain time following the noticed timing, an error display is made on the apparatus and the measurement is reset.

Systems and interfaces for blood sampling

The present invention generally relates to systems and methods for delivering and / or receiving a substance or substances such as blood from subjects. In one aspect, the present invention is directed to devices and methods for receiving or extracting blood from a subject, e.g., from the skin and / or from beneath the skin, using devices containing a substance transfer component (for example, one or more needles or microneedles) and a reduced pressure or vacuum chamber having an internal pressure less than atmospheric pressure prior to receiving blood. In some embodiments, the device may contain a “snap dome” or other deformable structure, which may be used, at least in part, to urge or move needles or other suitable substance transfer components into the skin of a subject. In some cases, for example, the device may contain a flexible concave member and a needle mechanically coupled to the flexible concave member.

Fluid sampling, analysis and delivery system

The lack of safe, reliable, automated and clinically acceptable blood sampling has been the main problem precluding the development of real-time systems for blood analysis and subsequent closed-loop physiological function control. While the analysis of a static blood sample in laboratory conditions has been rapidly advancing in reliability and blood volume reduction, non-invasive real-time blood analysis performed in vivo (while the blood is circulating in the body) has been elusive and unreliable. In this study we propose an innovative idea for semi-invasive blood sampling and analysis, which resembles the operation of a mosquito. At a miniature scale the proposed system does penetrate the skin to extract a static blood sample for further analysis, but the extent of this penetration, and the fact that it can be made painless, is particularly attractive for such applications as automated glucose analysis for closed-loop control of insulin infusion (artificial pancreas), continuous drug monitoring, or even periodic DNA analysis for security and identification purposes. These design aspects are described, and a specific implementation, applying MEMS (Micro Electro Mechanical Systems) technology, is suggested. The proposed microsystem is a matrix of individually controllable e-Mosquito™ cells, packaged in a disposable patch and attached to the skin, could be an avenue for real-time semi-invasive blood analysis and diagnostics.

Blood sampling device

A blood sampling device useful for collecting a blood sample from a separate vascular access device is described herein. The blood sampling device includes a body shaped and sized for partial insertion into a separate vascular access device. The body includes a reservoir defined within the body, which has an internal volume sufficient to contain enough blood for use in a diagnostic blood test. The body also includes a gas permeable vent disposed on the body, in which the gas permeable vent is in gaseous communication with the reservoir. When connected to a separate vascular access device the blood sampling device collects a blood sample as blood flows into the reservoir from the separate vascular access device and as gases pass out the reservoir via the gas permeable vent.
