The present disclosure relates to a body attachment unit for continuous blood glucose measurement, in which the body attachment unit is manufactured so as to be assembled in an applicator, thereby minimizing additional work and allowing attachment of the body attachment unit to a body simply by operation of the applicator. In particular, a wireless communication chip is provided in the body attachment unit to enable communication with an external terminal, thereby enabling simple and convenient use without performing additional work of connecting a separate transmitter, and allowing easier maintenance. In addition, activation occurs by a user's operation after the body attachment unit is attached to the body, such that an activation start point in time can be adjusted to an appropriate point in time according to the user's needs, and activation occurs in a stabilized state, thereby providing the body attachment unit allowing more accurate blood glucose measurement.

A cartridge is designed to secure and position a waste tube during a blood draw operation. The cartridge includes a T-shaped body with a tubular central portion and one or more gripping flanges. The tubular central portion has an open first end and an elongated cavity elongated cavity that is sized and shaped to receive the waste tube through the open first end. The one or more gripping flanges are attached to a second end of the tubular central portion opposite the first end and extend out away from the tubular central portion in a plane substantially perpendicular to elongated cavity. The cartridge further includes a plunger mechanism affixed to the T-shaped body. The plunger mechanism includes a stem adapted to slide into the cavity through the second end of tubular central portion responsive to an applied external force to eject the waste tube from the cavity through the open first end of the cavity.

There are provided a blood-collecting device by which a blood-collecting operation can be performed by single hand and the blood can be collected in a short time without a risk of hemolysis, and a blood-collecting tube usable for blood-collecting device. A blood-collecting tube, of which a tip portion is housed in a tube holding portion and which accommodates the blood coming out of a base end side of a needle tube, includes a tube structure opened at both ends, and a tube attached to the tube structure. A tip portion of the tube structure is housed in a hollow portion of a tube holding portion of a needle base. The tube preferably has elasticity. The tube is attached to the tube structure using elastic deformation of the tube, allowing the tube to be in close contact with an inner circumferential surface of the needle base.

An object is to perform analysis of a target component contained in a small volume of blood sample at high accuracy using a normal component homeostatically present in blood. Provided is a blood test kit for analyzing a concentration of a target component in a blood sample by using a normal component homeostatically present in blood, the kit including: a diluent solution for diluting a blood sample; and a member selected from the group consisting of a first storing instrument in which the diluent solution is stored, a separating instrument for separating and recovering blood plasma from the blood sample diluted with the diluent solution, a holding instrument for holding the separating instrument, a second storing instrument for storing the recovered blood plasma, and a sealing instrument for keeping the stored blood plasma in the second storing instrument, in which an amount of the normal component which is derived from the member and may be contained in the diluent solution is defined.

A blood sampling device (1) comprising a housing (10) and a lancet (50). The housing has a fixed abutment surface for holdingly engaging the lancet in a rearward primed position. The blood sampling device further comprises a trigger (22) moveable from a rest position to a fire position to release the lancet for forward movement, wherein the trigger deflects the lancet body in a direction generally transverse to the longitudinal axis of the housing such that the lancet body may move forwardly past the fixed abutment surface.

An object of the present invention is to provide a blood test kit of which a component in a small volume of blood can be mailed in a safe state by controlling the influence of the outside temperature during the mailing, and a highly accurate blood analysis method in which coefficient of variation of a measurement value is reduced. According to the present invention, a blood test kit including a diluent solution for diluting a blood sample; a separating means for recovering blood plasma components from the diluted blood sample; a container for storing the blood plasma components recovered from the diluted blood sample; and a cold insulation means for cold-insulating the container, is provided.

An object of the present invention is to provide a blood analysis method in which a high level of repeatability and reproducibility is achieved with respect to measurement values in a blood sample, and a blood test kit which is used for the blood analysis method. According to the present invention, a blood analysis method including a step of diluting a collected blood sample with a diluent solution; a step of quantitatively determining sodium ions in the diluent solution of the blood sample by using a solution containing -galactosidase and at least one substrate which is convertible by -galactosidase so as to determine a dilution factor from a normal value of serum and blood plasm sodium ions which are homeostatically present in the blood and the quantitative value of sodium ions; and a step of analyzing a concentration of a target component to be measured in the blood sample from the determined dilution factor and a measurement value of a concentration of the target component to be measured in the blood sample, in which the diluent solution is a diluent solution which does not contain sodium ions, is provided.
