Problems solved by technology

[0006] Currently, products that support stand-alone machines can use whole blood samples for blood routine parameter measurement and CRP parameter measurement, but the test speed is relatively slow, with a maximum test speed of only 20 samples / hour, which cannot meet the efficiency requirements in clinical testing

Embodiment 1

[0036] Please refer to figure 1 and figure 2 , is a structure of the blood testing instrument disclosed in this embodiment. in, figure 1 It is a schematic diagram of the three-dimensional structure of the blood detector, figure 2 It is a block diagram of the structure and principle of the blood detector; figure 2 The dotted arrow line in the figure is the direction of the electrical signal, and the solid arrow line is the direction of the liquid circuit. The blood tester includes: routine blood measurement module 1 ( figure 1Not shown in the marker), C-reactive protein measurement module (hereinafter also referred to as CRP measurement module) 2, sample collection and distribution module 3, liquid circuit support module 8 ( figure 1 Not shown in the mark) and the control and information processing module 9 ( figure 1 not shown). in:

[0037] The routine blood measurement module 1 is used to provide a measurement place for the allocated samples, measure the allocated...

Embodiment 2

[0063] The difference between this embodiment and the above-mentioned embodiments is that the blood detector disclosed in this embodiment also includes an automatic sampling module 4, such as figure 1 As shown, the automatic sampling module 4 provides continuous samples for the sample collection and distribution module 3 and completes sample loading and unloading. The automatic sampling module 4 is preferably arranged at the front end of the blood tester. Please refer to Figure 7 , is a top view diagram of the automatic sampling module, mainly including: a test tube rack conveying mechanism 41, a loading position detection mechanism 42, a test tube rack loading mechanism 43, a test tube rack unloading mechanism 44, a test tube presence detection mechanism 45 and a test tube barcode information acquisition mechanism 46. The working process is as follows: the test tube rack conveying part 41 transports the test tube rack with placed test tubes to the loading area 410 along the ...

Embodiment 3

[0076] The difference between this embodiment and the above-mentioned embodiment is that the blood detector disclosed in this embodiment also includes a latex reagent storage module 5, such as figure 1 As shown, the latex reagent storage module 5 is used to provide a low-temperature storage environment for the latex reagent, and the latex reagent storage module 5 is arranged in a position of the blood detector closer to the edge of the detector and away from the inside. The advantage of setting the latex reagent storage module 5 away from the inside of the detector is that it not only facilitates the replacement of latex reagents, but also prevents users from putting their hands into the inside of the instrument when replacing latex reagents, reducing the risk of biological contamination for users.

[0077] In the preferred embodiment, please refer to Figure 7 , the latex reagent storage module 5 can be arranged between the sample loading area 410 and the sample unloading are...

Abstract

A blood detector comprises a blood routine measurement module (1) and a C-reactive protein measurement module (2), the C-reactive protein measurement module (2) comprises a reaction container, one ormore measurement containers and a hemolytic agent conveying pipeline, the reaction container is used for receiving a sample and a latex reagent which are distributed by a sample collecting and distributing module, the measurement container(s) is(are) used for providing a measurement place for a reaction solution, the reaction container and the measurement container(s) are controllably communicatedthrough a sample conveying pipeline, a control and information processing module controls a liquid path support module to provide power in order to add a hemolytic agent to the reaction container through the hemolytic agent conveying pipeline, the hemolytic agent reacts with the blood sample an the latex reagent which are added later in the reaction container, and then the sample is conveyed intothe measurement container(s) through the sample conveying pipeline, so the measurement efficiency of C-reactive protein parameters is improved, and the measurement of the C-reactive protein parameters of multiple whole blood samples is rapidly completed.

Description

[0001] This application is a divisional application, the original application number is 201480039632.7, the application date is July 1, 2014, and the title of the invention is "A Whole Blood Sample Detection Method and Blood Detector". technical field [0002] The application relates to the field of blood detection and analysis, in particular to a blood detector, which is used to support routine blood cell detection and CRP detection using whole blood samples on a single machine. Background technique [0003] Now, in the clinical diagnosis of the hospital, it is often necessary to obtain the test results of the blood routine parameters and CRP (C-reactive protein) parameters of the patient's blood at the same time. [0004] In most existing blood testing instruments, routine blood tests such as blood cell counting and classification and CRP testing are performed on different instruments using different types of samples. Blood cell counting and classification are generally per...
