A wearable device comprising a display dial configured to display various health parameters, a wristband assisting the device to wear on wrist, an eject-able tray comprising a micro-chip, a first spring coupled to the eject-able tray, at least one latch provided with a second spring to hold the eject-able tray within the device by compressing the first spring, and a health monitoring unit provided with multiple sensors to determine various health parameters, wherein compression of the second spring results in the latch to release the eject-able tray which in turn relaxes the compressed first spring to eject the micro-chip outside the device for collecting blood samples. The microchip comprises at least one micro-needle and an enzyme test strip for collecting and analyzing the blood samples. The health monitoring unit comprises at least three conductive sense pads which are collectively operable to provide electrocardiograph (ECG) information.

The disposable module may include one or more lancet devices such as that described above to collect a biological sample, one or more strip stations supporting biological strips and a disposable module connector. The reusable module may support measuring equipment to measure a property of the biological sample and a reusable module connector that engages removably with the disposable module connector.

Disclosed is an apparatus for analyzing the composition of bodily fluid. The apparatus can include a fluid handling network including a patient end configured to maintain fluid communication with a bodily fluid in a patient and a pump unit in operative engagement with the fluid handling network. The pump unit can have an infusion mode, in which the pump unit is operable to deliver infusion fluid to the patient through the patient end, and a sample draw mode, in which the pump unit is operable to draw a sample of the bodily fluid from the patient through the patient end. The apparatus can include a spectroscopic analyzer positioned to analyze at least a portion of the sample; a processor in communication with or incorporated into the spectroscopic analyzer; and stored program instructions executable by the processor to obtain measurements of two or more properties of the sample.

Transdermal sampling and analysis device, method and system are provided for non-invasively and transdermally obtaining biological samples from a subject and determining levels of analytes of the obtained biological samples. The transdermal sampling and analysis device, method and system may cause disruption to the skin cells to create capillary-like channels from which biological samples may flow to the transdermal sampling and analysis device. The transdermal sampling and analysis device, method and system may collect the biological samples in a reservoir where the biological sample may chemically react with a biologically reactive element. A sensor may convert the produced electrons (ions) into measured electrical signals. The converted signals may be measured and the levels of an analyte may be determined based on the measured signals.

Various embodiments disclosed herein relate to detecting leaks in a patient monitoring system. The system can include a fluid handling network configured to receive a fluid sample drawn from a patient and to deliver at least a portion of the fluid sample to an analyte measurement system. The system can isolate at least a portion of the fluid handling network, can apply pressure to the at least a portion of the fluid handling network, can measure the pressure in the at least a portion of the fluid handling network, and can determine whether a leak is present in the at least a portion of the fluid handling network based at least in part on the measured pressure.

Methods and systems for manufacturing a transdermal sampling and analysis device for non-invasively and transdermally obtaining biological samples from a subject and determining levels of analytes of the obtained biological samples are provided. A method of manufacturing the device may improve performance and includes forming channel structures on the lid of the device, thereby making the spacer/channel support structures physically independent and separable from the sensing electrode. Other methods of manufacturing the device may improve performance and include forming at least one of the electrodes on each of the base and the lid, and forming a recessed second spacer layer over the channel support structures, thereby separating the channel support structures and the electrode on the lid to allow a larger area of the electrode to be exposed to the biological sample.

A system is provided for monitoring analyte in a host, including a continuous analyte sensor that produces a data stream indicative of a host's analyte concentration and a device that receives and records data from the data stream from the continuous analyte sensor. In one embodiment, the device includes a single point analyte monitor, from which it obtains an analyte value, and is configured to display only single point analyte measurement values, and not any analyte measurement values associated with data received from the continuous analyte sensor. Instead, data received from the continuous analyte sensor is used to provide alarms to the user when the analyte concentration and/or the rate of change of analyte concentration, as measured by the continuous analyte sensor, is above or below a predetermined range. Data received from the continuous analyte sensor may also be used to prompt the diabetic or caregiver to take certain actions, such as to perform another single point blood glucose measurement. In another embodiment, the device provides for toggling between two modes, with one mode that allows for display of glucose concentration values associated with the continuous glucose sensor and a second mode that prevents the display of glucose concentration values associated with the continuous glucose sensor.

In a housing configured to mount thereon a biosensor in an attachable and detachable manner in which the biosensor is configured to have a liquid sample of a biological object deposited thereon, the medial measuring device includes a measuring component operable to measure biological information from the liquid sample of the biological object, a recording component operable to store a result measured by the measuring component, and an information protection component operable to determine an access limitation to personal information data stored in the recording component. With this configuration of the device, it is possible to properly protect personal information stored in the device.

Disclosed are methods and apparatus for determining analyte concentration in a sample such as bodily fluid. Systems and methods disclosed herein can also include a treatment dosing system to infuse or inject a treatment drug (e.g., insulin or glucose) and provide glycemic control. The dose of the treatment drug may be based on the concentration of the analyte or the average value for the concentration of the analyte and/or the rate of change of the value of the concentration of the analyte.
