摘要:
Provided are a decompression mechanism capable of performing a desired pressure reduction by simple operation and having improved operability, a puncture device, a blood analysis device, and a sensor mounting mechanism. A needle puncturing device (100) is provided with: a piston (121) having at one end thereof an end part (121a) for forming a part of a sensor mounting mechanism (130) and at the other end an end part (121b) for slidably supporting a rod (112) of a lancet section (111); a cylinder (122) for slidably containing therein the end section (121b) of the piston (121); and packing (125) mounted to the inner periphery of the end part (121b) of the piston (121) and maintaining the air-tightness of the outer periphery of the rod (112). When the piston (121) is moved in the direction toward the cylinder (122) with a skin contact part (131) in contact with the skin, the volumes of an internal space (140) and a pressure reduction chamber (150) which are sealed by packing (123, 124) are increased to produce a reduced pressure.
摘要:
A blood test device (21) ensuring successful measurement wherein fingers scarcely slip out from the blood test device and blood never sticks to other sites in the course from the puncture of the patient's skin to the completion of the blood test. This blood test device (21) comprises a cartridge (24) in which sensors (23) pooling blood oozing out from the punctured skin are stored in a layered state, a transport unit transporting a single sensor sheet (23) from the inside of the cartridge (24) to the outside, a holder (25) holding the transported sensor (23), a laser emitting unit (26) puncturing the skin in the state where the sensor (23) is held by the holder (25), and a pump (28) keeping the inside of the holder (25) and the inside of the cartridge (24) under negative pressure.

The present biosensor system prevents a measurement error caused by the temperature of the environment in use. A biosensor system 100 includes a measuring instrument 101 having an operation part 306, and a sensor chip 200 insertable into and removable from the measuring instrument 101 and which accepts a blood sample. The sensor chip 200 includes a measurement part 41 that acquires Data a related to the concentration of an analyte in a blood sample based on the amount of electric current that flows in the sample due to a reaction in which an oxidoreductase with the analyte used as a substrate is involved, and a measurement part 42 that acquires, from the sample, Data b for temperature correction of Data a. The operation part 306 determines the concentration of the analyte in the sample, corrected according to the temperature of the sample based on Data a and Data b.

摘要:
A one pot method of preparing cyclic carbonyl compounds comprising an active pendant pentafluorophenyl carbonate group is disclosed. The cyclic carbonyl compounds can be polymerized by ring opening methods to form ROP polymers comprising repeat units comprising a side chain pentafluorophenyl carbonate group. Using a suitable nucleophile, the pendant pentafluorophenyl carbonate group can be selectively transformed into a variety of other functional groups before or after the ring opening polymerization.
