Haematocyte analyzer feeding mode and automatic feeding device

Abstract

A sending mode and the sending device automatically for the blood cell analysis instrument are to convert the tube to send the sample. The auto sending sample device includes the tube pushing device, the mixing device, the scan device and puncturing device. The tube pushing device is connected to the mixing device, the scan device and puncturing device. It will combine the mixing equip and scan device into one mixing scan device. The invention makes tube blood mix under the situation that the tube doesn't escape from a tube, and have good mixing efficient. But the blood collecting can be completed under the situation that the tube doesn't escape from a work. So it makes the puncturing sample more convenient and simple. It can further shorten the blood sample entering time, have operation more simple, the equipments are more cleverly made and the manufacturing cost is cheaper and higher automation degree.

Description

technical field [0001] The invention relates to a blood cell analyzer, in particular to a sample delivery method and a sample delivery device of the blood cell analyzer. Background technique [0002] At present, there are different methods and types of automatic sample feeding devices for blood cell analyzers, such as peripheral blood method, manual sample injection with cover open, manual sample injection with cover closed, emergency test sample injection, automatic sample injection, etc., and connected to a fully automatic assembly line automatic sampling technology, etc. Some sampling devices use rotary sampling trays, such as MEDONICCA570 and SWELAB AC920 / 970. More hematology analyzers adopt a flat-push automatic sampling system, that is, insert the sample to be tested into a special test tube rack, and the instrument will send the test tube rack into the sampling port of the instrument step by step, and automatically push it out after the measurement is completed, for ...

AI Technical Summary

Problems solved by technology

[0003] 1. In most domestic hematology analyzers, the blood sampling, manual sampling by opening the cover, manual sampling by closing the cover, and barcode identification of the sample tube for emergency inspection are all done manually. The work is cumbersome and error-prone, and the work Personnel may be in direct contact with blood samples, seriously affecting the safety of medical staff

[0004] 2. In recent years, the blood cell analyzers at home and abroad adopt automatic sample feeding, adopt rotary sample feeding tray, and flat push automatic sampling system are all large-scale equipment with surprisingly large volume, and the equipment needs to be imported. High cost, complex operation and inconvenient maintenance are not acceptable to major domestic hospitals

[0005] 3. Most of the puncture devices of hematology analyzers use cylinders as the puncture power for automatic puncture, which require special air source equipment and are large in size; linear motors are used as puncture power, but their cost is relatively high compared with ordinary stepping motors

[0006] 4. The mixing and scanning device of the blood cell analyzer mostly adopts manual mixing and scanning, the mixing effect is different, the scanning speed is slow, and the work efficiency is low; the mechanical arm swing mixing method is adopted, and the test tube needs to leave the test tube rack for mixing. The barcode scanning is automatically scanned at another station, and the blood sample mixing is not completed at the same station. The completion of the two work processes requires a large work space, which affects the volume and cost of the equipment.
