Embodiment 1

[0124] manufacture figure 1 Circuit board for blood collection shown

[0125] First, prepare an elongated sheet-shaped metal substrate made of SUS430 with a thickness of 50 μm (see Figure 5 (a)).

[0126] Next, a varnish of a photosensitive polyimide resin precursor (photosensitive polyamic acid resin) is applied on the surface of the metal substrate, heated and dried to form a cover film, and then exposed and developed to form a cover film as pattern. Then, an insulating base layer with a thickness of 10 μm was formed in the above pattern by heating to 400° C. in a nitrogen atmosphere (see Figure 5 (b)).

[0127] Next, a metal thin film made of a chromium thin film and a metal thin film made of a copper thin film are sequentially formed on the surface of the insulating base layer by means of sputtering. Then, a dry film resist is laminated on the surface of the metal thin film, and exposure and development are performed to form a plating resist layer in a pattern. T...

Abstract

The present invention provides a circuit board for collecting body fluid and a biosensor. The circuit board for collecting the body fluid comprises a plurality of measuring units and each of the units is equipped with a lancet needle and an electrode to be contacted with the body fluid collected by puncturing a body with the lancet needle. The measuring units are radially disposed on a same plane.

Description

technical field [0001] The present invention relates to a circuit substrate for body fluid collection and a biosensor, and specifically provides a circuit substrate for body fluid collection and a biosensor having the circuit substrate for body fluid collection. Background technique [0002] Diabetes has insulin-dependent (type I) and non-insulin-dependent (type II), and the former requires regular insulin supplementation. Therefore, when suffering from the former type of diabetes, it is often used to allow the patient to collect blood by himself, measure the blood sugar level by himself, and then supplement himself with insulin in an amount corresponding to the blood sugar level. [0003] Known is a kind of blood glucose measuring device specially developed for this kind of patient, which can allow the patient to draw blood independently and measure the blood glucose level. [0004] For example, a fluid collection device is proposed, which includes a reaction area inserted...
