Embodiment 1

[0036] Embodiment 1, see attached figure 1 , 2 , a self-calibrating measuring device, the entire self-calibrating measuring device is set in a portable testing instrument to form a completed portable testing instrument, specifically, the self-calibrating measuring device includes a calibration liquid pool 1, a waste liquid pool 2, a detection sensor 3 and a mobile detection module 4. The size of the calibration liquid pool 1 and the waste liquid pool 2 is set according to actual needs, which can be two containers, or can be set on a container on the casing of a portable detection instrument. The mobile detection module 4 can move linearly, and is controlled by a linear motor 8 Driven, the linear motor 8 is arranged in the portable detection instrument, and when installing, between the mobile detection module 4 and the housing of the portable detection instrument, a linear guide pair or a similar structure is provided to guide the waste liquid pool 2 and the second The first f...

Embodiment 2

[0042] Embodiment 2, see attached figure 2, in this embodiment, the first elastic closure module 501 includes two first elastic blocks 501a made of elastic material, the elastic material can be polyurethane or elastic rubber, two adjacent elastic blocks 501a The sides are fitted together to form a fitting seam, and the fitting seam is aligned with the first capillary duct 403. Preferably, the middle position of the fitting seam is aligned with the first capillary duct 403. This fitting seam can make The first capillary guide tube 403 passes through, and when the first capillary guide tube 403 is located therein, it can be closed and not in a conducting state, and the detected liquid connection port 502 is arranged on the two first elastic blocks The end part of 501a is used for installing the sampling head, absorbing the liquid to be detected, and communicates with the bonding seam in the waste liquid channel 503, and it is provided with a sealing ring for sealing.

Abstract

The invention discloses a self-calibration measuring device. The self-calibration measuring device comprises a calibration solution pool, a waste solution pool, a detection sensor and a movable detection module, wherein the waste solution pool is communicated with a first fixed module, and the calibration solution pool is communicated with a second fixed module; the first fixed module and the second fixed module are respectively positioned on the two sides of the movable detection module, the movable detection module comprises a movable block, and a measuring pool is arranged in the movable block; the detection sensor is arranged in the measuring pool, the movable block is provided with a first capillary guiding pipe and a second capillary guiding pipe which are communicated with the measuring pool, and orientations of a free opening end of the first capillary guiding pipe and a free opening end of the second capillary guiding pipe are opposite. The measuring device provided by the invention has the advantages that hundreds of times of sample measurement can be achieved, the whole complexity is far lower than that of the modularity instrument at present; the self-calibration measuring device comprises the simplicity and micromation of a dry-type chip instrument and also comprises the high reliability and the multi-time measuring characteristic of the modularity instrument, and the detection cost of a single time is low.

Description

technical field [0001] The invention relates to the technical field of liquid detection, and more specifically relates to a self-calibrating measuring device and a portable detecting instrument with the self-calibrating measuring device. Background technique [0002] At present, medical diagnosis, industrial production, environmental protection and other fields need to measure quickly and accurately on the spot. Detection is also the key development field of domestic and international analytical and testing instruments. [0003] In this technical field, it is mainly divided into two categories, one is to miniaturize and integrate the instrument, and cancel the auxiliary devices connected externally to the traditional instrument, such as reagent bottles, calibration solutions, sample injectors, and detectors, and design these parts as module, and integrated into a smaller instrument to form a whole that can be easily moved (for example, patent numbers: US 5750881, 5580790, 5...
