Separable cassette for measuring glycated hemoglobin
The present invention relates to a separable cassette for measuring glycated hemoglobin. It is easy to use the separable cassette for measuring glycated hemoglobin of the present invention since a reagent is sequentially leaked during the rotation thereof. In addition, there is no need to shake the reagent beforehand, as the reagent without residual reagent is fully discharged by the rotation. Therefore, the measurement result is accurate because an error between the amount of the reagent used and the amount of sample blood is small.
Kits And Devices For Detecting Analytes
The invention provides devices that improve tests for detecting specific cellular, viral, and molecular targets in clinical, industrial, or environmental samples. The invention permits efficient detection of individual microscopic targets at low magnification for highly sensitive testing. The invention does not require washing steps and thus allows sensitive and specific detection while simplifying manual operation and lowering costs and complexity in automated operation. In short, the invention provides devices that can deliver rapid, accurate, and quantitative, easy-to-use, and cost-effective tests.
SORTING A DROPLET INCLUDING A BIOLOGIC SAMPLE
Examples herein involve sorting a droplet including a biologic sample. In a particular example, sorting a droplet including a biologic sample includes generating a droplet including a biologic sample and a pH sensitive surfactant, and heating a nucleic acid molecule in the biologic sample. The pH sensitive surfactant may change the surface tension of the droplet responsive to amplification of the nucleic acid molecule. The droplet may be sorted into one of a plurality of sorting lanes based on the surface tension of the droplet, where a sorting lane among the plurality of sorting lanes is associated with droplets including the amplified nucleic acid molecule. A determination of whether the droplet includes the amplified nucleic acid molecule may be performed by detecting passage of the droplet in one of the plurality of sorting lanes.
Biological sample reaction box
A biological sample reaction vessel comprising a reagent storage portion and a push rod movable relative to the reagent storage portion is provided. The reagent storage portion comprises at least one reagent containing cavity, and the reagent containing cavity is sealed by a sealing element; and the push rod is connected to the sealing element, and the push rod is used for cooperation with an external device to separate the sealing element from the reagent storage portion. In reaction, the biological sample reaction vessel cooperates with a test cassette. By inserting the biological sample reaction vessel into the external device, the reagent in the reagent storage portion can be released rapidly.

Apparatus and method for metered dispensing of a microfluidic amount of fluid in the picoliter and microliter range and hand-held device for locally piercing human or animal skin
Metered dispensing of a microfluidic amount of fluid from a reservoir comprises a pressure device which applies a discharge pressure for fluid ejection via a discharge line through a valve arrangement. The valve device has a first valve with a minimum closing time and a second valve with a minimum opening time. A control device provides control signals for operation for metered dispensing of the amount of fluid as follows: a shortened minimum opening time for freeing the discharge line for the fluid flow, which time is shorter than the minimum opening time of the second valve; and a shortened minimum closing time for closing the discharge line for the fluid flow, which time is shorter than the minimum closing time of the first valve. Furthermore, a hand-held device for locally piercing human or animal skin is disclosed.
