A vial and system are configured to simplify fluid input and extraction therefrom. The vial has a first end opposite a second end and with a collapsible sidewall. The sidewall can be collapsed, such as by imparting a differential pressure between an interior and exterior of the vial, for simplified fluid extraction and smooth extraction without disturbing boundaries between separated components. The vial typically has a bulb at a first end and a neck extending away from the bulb and toward the second end. An inlet spaced from the first end can be configured to attach to various different interfaces or processing elements for input and output of fluids. A support cup can be provided for use with the vial during centrifugation to allow the vial to withstand any centrifugation forces. Various fluid processing methodologies are supported by the collapsible vial, especially including methods of separation of components of blood.

A body fluid analyte detection device, includes: a transmitter, provided with at least one first fastener part; a bottom case, provided with at least one second fastener part corresponding to the first fastener part, and the bottom case including at least one fixed portion and at least one force-receiving portion. When separating the bottom case and the transmitter, the fixed portion is fixed and a force is applied to the force-receiving portion in one direction, separating the bottom case and the transmitter. The body fluid analyte detection device further includes a sensor connected with the transmitter to transmit the parameter signal; and a battery assembled in the bottom case or in the transmitter. The part holding the battery is the battery portion. A force is applied to the force-receiving portion in only one direction to make the bottom case fail and thereby separating the transmitter and the bottom case, simplifying user action and enhancing user experience.

The present disclosure relates to an immunoassay method for performing immunoassay by using a patch that contains antibodies. An immunoassay method according to an aspect of the present disclosure performs diagnosis by detecting a target protein from a sample to be diagnosed by using a patch which includes a mesh structural body forming micro-cavities and is configured to contain a liquid substance in the micro-cavities, and includes placing the sample to be diagnosed in a reaction region, and providing an antibodies that react specifically with a target protein to the reaction region by using a patch that contains the antibodies.

The present disclosure relates to a gel-phase patch that performs a function of assisting in staining during a staining process such as a process of coming into contact with a specimen such as blood to perform a staining function of staining the specimen, a process of fixing the specimen, or a process of forming an optimal pH at a specimen stained by a staining sample. According to an aspect of the present disclosure, a contact-type staining patch includes a staining solution that reacts with a specimen and a gel receptor provided as a gel matrix of a mesh structure in which a pore that accommodates the staining solution is formed and the mesh structure prevents the staining solution in the pore from leaking or degenerating, and having a contact surface that comes into contact with the specimen to transfer some of the staining solution to the specimen.

According to an aspect of the present disclosure, there is provided a polymerase chain reaction (PCR) patch which is provided as a gel type having a net-like structure forming micro-cavities, wherein at least a part of a plurality of reagents used in a PCR are contained in the micro-cavities, and when the patch contacts with an external region, the reagents contained in the micro-cavities move to at least a portion of the external region, and a PCR of a target DNA included in a sample located in the external region is performed.

A highly integrated intelligent analyte detection device, includes: a bottom case including a first connection region; a transmitter including a transmitter case and an internal circuit, the internal circuit including at least two second electrical connection ends and at least two first electrical connection ends, at least two first electrical connection ends electrically conductive; a sensor including a signal output portion and a detection portion, and the signal output portion provided with at least two third electrical connection ends; and a second connection region including at least two conductive areas and at least one insulation area, and at least two third electrical connection ends respectively electrically connected to the corresponding second electrical connection ends, reducing the complexity of internal structure in the device and the size of the device, thus enhancing the user experience.

Apparatus and methods for separating blood components are disclosed in which an apparatus for separating blood generally includes a tube defining a channel and configured for receiving a quantity of blood and a float contained within the tube and having a density which is predefined so that the float is maintained at equilibrium between a first layer formed from a first fractional component of the blood and a second layer formed from a second fractional component of the blood. Upon completion of the centrifugation, the first layer may be removed from the tube while the float isolates the second layer from the first layer.
