Problems solved by technology

In the prior art, the photon collection port of the photon counter is always open. When the top cover of the measurement chamber is opened and placed or the cuvette is removed, external light will enter the photon counter, thereby affecting the service life and accuracy of the photon counter.

Embodiment 1

[0026] This embodiment provides a single cuvette luminescence measurement device, such as figure 1 or 2: Include:

[0027] The measurement chamber 1 is open at the top, and has an accommodating cavity for cuvettes inside, and a guide rail 12 on the top, a photon hole on the side, and a switch cover driver 14 installed;

[0028] The top cover 2 is slidably arranged on the guide rail 12 at the top of the measurement chamber 1, and can move along the guide rail 12 under the drive of the switch cover driver 14, so as to be between the position of closing the opening of the measurement chamber 1 and the position of opening the opening of the measurement chamber 1 The top cover 2 is also provided with a reagent adding tube 21. When the top cover 2 is in the position of closing the opening of the measurement chamber 1, the liquid can flow into the cuvette located in the accommodating chamber by injecting the liquid into the reagent adding tube 21, which is convenient for various reac...

Abstract

The invention relates to a single reaction cup luminescent measurement chamber. The single reaction cup luminescent measurement chamber comprises: a measuring chamber, a top cover; a photon counter; a shutter structure, which is arranged between the photon counter and the measurement chamber and can close or open a photon via hole. Through the design of the shutter structure, before opening of the top cover, a driving part is rotated to drive the movement of a baffle plate, so that a through hole on the baffle plate and the photon via hole can be staggered, i.e. a lens of the photon counter can be shielded to prevent the incidence of external light into the photon counter, thus ensuring the service life and precision of the photon counter. After close of the top cover, the driving part is rotated to drive the baffle plate to move, so that the through hole on the baffle plate can coincide with the photon via hole, therefore the photon counter can collect the luminescent amount of a substance in a reaction cup.

Description

technical field [0001] The invention relates to a single cuvette light-emitting measurement chamber, which belongs to the technical field of medical instruments. Background technique [0002] At present, in vitro diagnosis is the most widely used diagnostic method in the medical field, which refers to collecting body fluids, excreta, and secretions of the human body for chemical composition or chemical reaction analysis, so as to determine human pathological changes. Such as chemiluminescence analysis, molecular diagnosis. These diagnostic methods all use automatic or semi-automatic instruments to add samples, analyze, and give diagnostic reports. This type of instrument has a functional unit—the luminescence value detection unit (that is, the measurement chamber). The measurement chamber is a container structure that can be closed. After the reaction in the measurement chamber emits light, the photon counter measures the number of collected photons, and finally performs qu...
