Claims

[Claims for Utility Model Registration] 1. A body fluid measuring device having an electrode 3 for body fluid measurement at a predetermined position of a casing 1, and an external cover 2 that can be opened and closed in accordance with the electrode position, It moves in conjunction with the opening/closing operation of the outer cover 2, and when the outer cover 2 is open, the electrode 3
An infection prevention mechanism in a body fluid measuring device, characterized in that an internal cover 5 is provided to cover at least a portion of the body fluid measuring device. 2. The infection prevention mechanism in the body fluid measuring device according to claim 1, wherein the inner cover 5 has a large diameter opening 53 that directly faces the electrode 3 when the outer cover 2 is in the closed state. 3. Infection prevention mechanism in the body fluid measuring device according to claim 2 of the above-mentioned utility model registration claim, in which the electrode 3 comes into contact with the wetting liquid holding portion provided in the outer cover 2 through the large-diameter opening 53 when the outer cover 2 is in the closed state. . 4 When the outer cover 2 is in an open state, the electrode 3 passes through the space below the inner cover 5 to the diffusion limiting membrane 4.
Claim 1 of the above-mentioned utility model registration with reference 4.
3. An infection prevention mechanism in the body fluid measuring device according to any one of items 3 to 3. 5 The outer cover 2 is rotatably attached to the casing 1, and the inner cover 5 is slidably attached to the casing 1, and the base of the outer cover 2 and a predetermined position of the inner cover 5 are linked. An infection prevention mechanism in a body fluid measuring device according to any one of claims 1 to 4, which is connected by a member 28. 6 The inner cover 5 has a pair of protrusions 51 that engage with a pair of guide grooves 52 formed at predetermined positions of the casing 1, and the protrusions 51 are connected to the outer cover 2 by the link member 28. An infection prevention mechanism in a body fluid measuring device according to claim 5 of the above-mentioned utility model registration.
