Embodiment Construction

[0037] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0038] Such as Figure 1 ~ Figure 3 As shown, the body fluid measurement device 10 of the preferred embodiment of the present invention is used after fitting a blood sampling needle holder 30 to the front end 21 of the cylindrical body of the main body 20. An LCD display 22 may be installed on the outside of the main body 20, and a small speaker (not shown) that informs the user of the measurement status by sounding is installed inside the LCD display 22. In addition, the main body 20 is also equipped with: a lancet operating mechanism for advancing the lancet 31 held on the lancet holder 30; a sensor moving mechanism for advancing the biosensor 36; and an electronic circuit 33 such as a microcomputer (see appendix Figure 6 ).

[0039] The lancet operating mechanism that advances the lancet 31 is composed of a squeeze rod 23 that protrudes from the rear end of the...

Abstract

A body fluid measuring apparatus includes a main body (20) and a lancet holder (30) for attachment to the main body (20). The lancet holder (30) includes a lancet (31) which is movable for stabbing a skin (S) to draw body fluid, and a biosensor (36) for introducing the drawn body fluid to perform predetermined measurement. The biosensor (36) is moved in a predetermined direction by a sensor moving mechanism (40, 42).

Description

Technical field: [0001] The present invention relates to a body fluid measuring device with a blood sampling needle, which can collect and measure a substance to be detected in body fluids such as blood sugar concentration (hereinafter referred to as blood sugar level) with a single operation. The invention also relates to a blood sampling needle holder that can be freely detached and assembled with the body fluid measuring device. technical background: [0002] In the treatment of diabetes, it is necessary to keep the patient's blood glucose level within the normal range, and it is also important for the patient to manage the blood glucose level by himself. Especially when the patient maintains the normal blood glucose range by injecting insulin himself, it is indispensable for the patient to measure the blood glucose value in a timely manner. [0003] To achieve this goal, there are currently commercially available portable blood glucose measurement devices, such as the blood g...
