Problems solved by technology

[0003]The existing blood cell analyzer sampling device is realized by the motor driving the belt to move back and forth, and its linear motion guide mechanism is a combination of linear bearing and linear guide shaft. In high-level medical equipment, the guiding accuracy of linear bearings has been difficult to meet the requirements of accurate positioning. Due to the compact structure and the long guide shaft, there are two problems: 1. Insufficient rigidity of the guide shaft leads to reduced guide accuracy
2. Although the guide shafts arranged in parallel can improve the accuracy, they have high requirements for assembly and inconvenient maintenance

Embodiment 1

[0022] Such as Figure 1-5 As shown, this embodiment discloses a sample feeding device for a blood cell analyzer, which includes a test tube sample rack loading tray 10, a timing belt 20, a timing belt pulley 30 that drives the timing belt 20 to reciprocate, and a motor that drives the timing belt pulley 30 to rotate 40 and guide mechanism 50. The combination of the synchronous belt 20, the synchronous pulley 30 and the motor 40 forms the driving part of the sampling device.

[0023] Such as Figure 1-2 As shown, the guide mechanism 50 includes a linear slide rail 51 parallel to the timing belt 20 and a slider 52 capable of sliding on the linear slide rail 51 . The slider 52 is fixedly connected to the timing belt 20 and moved by the motor 40 . There are two linear slide rails 51, and the loading tray 10 is arranged between the two slide rails 51 for loading the sample racks with the sample tubes placed therein. A push block 53 for pushing the sample rack is riveted on the ...

Embodiment 2

[0029] Such as Figure 6 As shown, this embodiment provides an automatic sample tube delivery system for a hematology analyzer, including the above-mentioned sampling device, and also includes a sample dragging device 80 and a mixing device 90; the sample dragging device 80 is used to transport the sample feeding device to The test tube sample rack at the designated position is transported to the mixing device 90 , and the mixing device 90 stops after shaking for a predetermined number of times or time, and the sample dragging device 80 sends the test tube sample rack out of the mixing device 90 .

Abstract

The invention relates to the technical field of medical and health apparatuses, particularly to a sample introduction device of a blood cell analyzer. The sample introduction device includes a test tube sample holder loading disc, a synchronous belt, synchronous pulleys driving the synchronous belt to do reciprocating motion, a motor driving the synchronous pulleys to rotate and a guide mechanism. The guide mechanism includes linear slide rails parallel to the synchronous belt and a sliding block able to slide on the linear slide rails. The sliding block is in fixed connection with the synchronous belt and is driven by the motor to move. The sample introduction device also includes a push block that is fixed on the sliding block and does reciprocating motion along with the synchronous belt. Under the driving of the push block, the test tube loaded test tube sample holder is conveyed to a specific location along the guide mechanism. The device provided by the invention employs the linear guide rails to replace existing linear bearings to serve as the guide transmission mechanism, the load is large, the stability is stronger, and the rigidity is enough.

Description

technical field [0001] The invention relates to the technical field of medical and health instruments, in particular to a sample feeding device for a blood cell analyzer. Background technique [0002] Blood cell analyzer is one of the most widely used instruments in hospital clinical examination. With the rapid development of computer technology, blood cell analysis has also changed from three-dimensional to five-group, from two-dimensional space to three-dimensional space, and we have also noticed that modern blood cell The analyzer's five-differentiation technology uses the same technology as today's most advanced flow cytometers, such as scattered light detection technology, sheath flow technology, laser technology and so on. [0003] The existing blood cell analyzer sampling device is realized by the motor driving the belt to move back and forth. Its linear motion guiding mechanism is a combination of linear bearings and linear guide shafts. In medical equipment with a h...
