Problems solved by technology

[0003] However, the current chemiluminescence tester products are mainly high-throughput equipment. The reagents are in a low-temperature state and cannot be heated for a long time. They are incubated only when the sample is tested, and the incubation time is often as high as 18 minutes or more. Causes diagnosis time to be too long, so as to delay patient's treatment

[0032] Please refer to figure 1 , the present embodiment provides a pre-incubation device 100 for chemiluminescence rapid diagnosis, including a base 110, a working disk 120, and a plurality of heating components. The working disk 120 is connected to the base 110 , and a plurality of heating components are disposed on the bottom of the working disk 120 .

[0033] The working disk 120 is roughly ring-shaped. The working disk 120 is used to place reagent and medicine boxes, magnetic bead cups and reagent tubes. Since the shapes of these boxes are different, the width of each section of the ring formed by the working disk 120 is not the same. In this embodiment, preferably, the working disk 120 is set to be ring-shaped at each segment according to the shape of the reagent drug box, the magnetic bead cup and the reagent tube, but the entire working disk 120 forms a ring shape. The arc length of the ring is variable according to the set capacity to accommodate the reagent drug bo...

[0055] Please refer to image 3 This embodiment provides a pre-incubation assembly 200 for chemiluminescence rapid diagnosis, which includes the pre-incubation device 100 for chemiluminescence rapid diagnosis provided in the first embodiment and aspiration needle assembly 210 . The suction needle assembly 210 is rotatably disposed in the ring of the annular working disk 120 , so that the rotation range of the suction needle assembly 210 covers the reagent disk 121 and the pre-incubation disk 122 .

[0056] Specifically, the aspiration needle assembly 210 includes a driving mechanism 214 and an aspiration needle body 212 . Wherein, the driving mechanism 214 is used to drive the suction needle body 212 to rotate, and the suction needle body 212 is used to suck reagents and magnetic beads and add them into the sample tube.

[0057] In this embodiment, preferably, the suction needle body 212 includes a suction needle head 218 and a rotating shaft 217, one end of the rotating shaf...

[0063] Please refer to Figure 4 , this embodiment provides a method for rapid diagnosis of chemiluminescence. Diagnosis is performed by using the pre-incubation component 200 for chemiluminescent rapid diagnosis provided in the third embodiment. Specifically, the rapid diagnosis method method includes the following steps:

[0064] S1. Preheat the reagents and magnetic beads placed on the reagent plate 121, and heat the samples placed on the pre-incubation plate 122;

[0065] In this embodiment, when preheating the reagents and magnetic beads, the preheating temperature is 30±0.5°C;

[0066] The sample is heated, and the heating temperature is 37±0.5°C.

[0067] S2. Aspirate the preheated reagent and magnetic beads through the aspirating needle assembly 210, and add them to the sample, so that the sample reacts with the reagent and magnetic beads.

[0068] By preheating the reagents and magnetic beads before the sample is added to the test, this detection method can greatl...

Abstract

The invention relates to the field of a medical appliance, in particular to a chemiluminescence fast diagnosis preincubation device, a preincubation assembly and a method. Through the arrangement of an independent heating preincubation disc and a reagent disc, reagents and magnetic beads are preheated in advance; through the matching of a suction needle assembly and the preincubation device, the instant detection of the sample is realized; the sample detection time can be saved; the sample detection efficiency is effectively improved. During the sample detection, the preheated reagents and the magnetic beads can be directly added into a sample for chemical reaction; the incubation time of the reagents and the magnetic beads is greatly shortened. The method belongs to a fast diagnosis method.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a pre-incubation device, a pre-incubation component and a method for rapid chemiluminescence diagnosis. Background technique [0002] The automatic chemiluminescence immunoassay analyzer is a fully automatic medical testing instrument that analyzes the human body's immunity by detecting the patient's blood, which is of great significance to clinical medicine. The reagent is incubated to reach the temperature at which the reagent reacts with the sample, thereby realizing the detection of the sample. [0003] However, the current chemiluminescence tester products are mainly high-throughput equipment. The reagents are in a low-temperature state and cannot be heated for a long time. They are incubated only when the sample is tested, and the incubation time is often as high as 18 minutes or more. Cause diagnosis time is too long, so as to delay the treatment of patients.
