BLOOD GLUCOSE MANAGEMENT SYSTEM
A biological property testing device includes a base comprising a primary surface extending in a base plane, and a first lancet station supported by the base. A first test strip channel provided in the base can have a main channel portion extending generally parallel with the base plane, and an angled channel portion that forms an angle with the main channel portion between 5 degrees and 90 degrees. The first test strip channel can house a biological test strip oriented so that a meter connecting end of the biological test strip is adjacent to the main channel portion and a sample end of the biological test strip is adjacent to the angled channel portion.
Absorbent articles comprising sensors
A sensor system for detecting a property of or within an absorbent article may comprise an absorbent article and a sensor. The absorbent article may comprise a garment-facing layer and an absorbent assembly. The sensor may be disposed in and/or on the absorbent article. The sensor may be separable from the absorbent article. The sensor may be configured to sense a change in condition within the absorbent article.
Vial with lid attachment mechanism
A re-sealable container is disclosed having a lid, a body, an attachment mechanism, and a seal. The seal may extend from, or be attached to, the lid and engage at least a portion of the body, such as the side wall, including the body sealing surface and/or the lip. The engagement of the seal and body creates a seal that prevents the ingress of moisture and ambient conditions into an interior space of the body. The attachment mechanism may retain the lid in a seated, closed position on the body. The configuration of the seal and attachment mechanism accommodate a degree of error in the joining and placement of the lid and body while allowing for both the formation of a seal between the lid and body and the locking of the lid when the lid is in a closed position.
Fluidic channels including conductivity sensor and methods of use thereof
Devices that includes a first portion, the first portion including at least one fluid channel; a fluid actuator; an analysis sensor disposed within the fluid channel; a conductivity sensor disposed within the fluid channel; and an introducer; a second portion, the second portion comprising: at least one well, the well containing at least one material, wherein one of the first or second portion is moveable with respect to the other, wherein the introducer is configured to obtain at least a portion of the material from the at least one well and deliver it to the fluid channel, and wherein the fluid actuator is configured to move at least a portion of the material in the fluid channel.
Sorting biological and non-biological moieties using magnetic levitation
Systems and methods for levitating populations of moieties, cells, or other such units using one or more magnets in a microfluidic environment are provided. These systems and methods may be used to, for example, separate or sort heterogeneous populations of the units from one another, to assembly a multi-unit assembly during the levitating of the units, and to evaluate samples at the point of care in real-time. These systems and methods may also utilize a frame that enables an imaging device, such as a smartphone, to capture the units in real time as they are manipulated in the system.
Method and devices for detecting viruses and bacterial pathogens
The embodiments disclose a method including functionalizing a biosensor with a biologic analytical target prior to installation into a detection cartridge, depositing a test subject bodily fluid test sample onto the biosensor surface, inserting the detection cartridge into a portable detection cartridge reader, measuring the electrical impedance of the bodily fluid test sample across biosensor energized electrodes, providing algorithms for analyzing measured electrical impedance data of the bodily fluid test sample obtained in the detection cartridge, identifying and determining the presence of biologic analytical target molecules in the bodily fluid test sample, and transmitting results of the test results to the test subject.
Tear flow measurement device
A lacrimal tear flow measurement device, and methods of manufacture and use, are described that includes a polymer microcapillary tube or similar structure having at least one end coated on the outside with soft silicone rubber and one end treated on the inside to be hydrophobic. The hydrophobic end keeps liquid from escaping or entering that end while allowing air to pass. The rest of the tube's insides may be hydrophilic or a neutral hydrophobe. As a Schirmer's test strip replacement, the entrance end of the device can be touched to the lacrimal lake of a patient's eye to collect suck up, or merely collect, tear fluid within the collection tube for weighing, volume measurement, or other analysis. Long-term collection devices for wear between doctors' visits can have a bypass channel allowing liquid to flow back onto the eye.
Detection Method and Device
The disclosure concerns a method and a device for enriching cells, cell fragments and molecules from whole blood for a specific detection of at least one population of cells, cell fragments or molecules contained therein. The task was to detect a broad spectrum of target objects including their molecules simply, quickly and yet sensitively and specifically from whole blood. According to the disclosure, not the target objects themselves, but matrix objects are specifically enriched, but target objects are specifically analyzed and thus a specific and sensitive detection of target objects is achieved.
POROUS MEMBRANE FOR SINGLE PARTICLE ANALYSIS
The present invention relates to a porous membrane including a plurality of through-type pores, and when the porous membrane is used, a particle to be analyzed and a reactive particle may be reacted one-to-one, thereby increasing the efficiency and accuracy of particle analysis.
METHODS AND SYSTEMS FOR HIGH-THROUGHPUT PATHOGEN TESTING
Disclosed are methods and systems for high-throughput testing of pathogens, and in some instances, testing for SARS-CoV-2. For example, disclosed is a method for intelligently selecting samples to perform a pooled testing for a pathogen including the steps of obtaining samples from multiple regions/populations, determining a prevalence of the pathogen in the samples from each region/population, determining an optimal selection plan to perform the pooled testing, selecting and combining samples based on the optimal selection plan, aliquoting the samples in the combined sample set based on the optimal selection plan, pooling and testing the samples in the combined sample set based on the optimal pooling design to determine a presence or absence of a detectable amount of the pathogen in each of the pooled samples, and determining whether at least one individual sample comprises the detectable amount of the pathogen.
