Hematology analyzer single sample feeding device applicable to different test tubes

Abstract

The invention provides a hematology analyzer single sample feeding device applicable to different test tubes. The hematology analyzer single sample feeding device comprises a single sample feeding seat, wherein a test tube seat with a plurality of tube positions is inserted into the single sample feeding seat; the bottom of the single sample feeding seat is mounted on a rotary shaft of the singlesample feeding seat; an upward vertical arm and a frontward cantilever are arranged at the left side and the right side of the single sample feeding seat respectively; the cantilever is provided witha counter weight; the hematology analyzer single sample feeding device further comprises a stopping block arranged at one side of the cantilever; the stopping block is mounted on an uncapping rotary shaft through a torsion spring; a stopping head at one side of the stopping block is correspondingly arranged at the bottom of the cantilever; the hematology analyzer single sample feeding device further comprises a cover shell; a cover cap is arranged on a front shell surface of the cover shell; an uncapping press button is arranged on the front shell surface of the cover shell; at a returning position of the uncapping press button, the stopping head is rotated to the bottom of the cantilever by the uncapping rotary shaft so as to limit the single sample feeding seat to a vertical position; ata pressing-down position of the uncapping press button, the stopping head is rotated by the uncapping rotary shaft to leave away from the bottom of the cantilever, the single sample feeding seat is rotated out forward and the vertical arm jacks the cover cap frontward. According to the hematology analyzer single sample feeding device provided by the invention, vertical sample placement and sampling is converted into inclined vertical sample placement and sampling, so that sample placement and sampling operation is facilitated better.

Description

technical field [0001] The invention relates to a medical device, in particular to a single-sampling device for a blood analyzer adapted to different test tubes. Background technique [0002] At present, most blood cell analyzers are mainly used for qualitative and quantitative analysis of blood cells in clinical tests, and after gradual improvement and development, not only the measurement data is more reliable, the measurement parameters are continuously increasing, and the automation level has also been greatly improved. [0003] Now, when many types of cell analyzers only perform individual or a few sample tests, they usually directly mix the blood in the test tube manually, and then let the hematology analyzer perform an automatic suction action through a single sampling device, thereby Complete the injection operation. [0004] However, the general single-sampling mechanism usually only provides a sampling device for test tubes of the same specification, and cannot be...

Problems solved by technology

[0004] However, the general single-sampling mechanism usually only provides a sampling device for test tubes of the same specification, and cannot be used for test tubes of different specifications at the same time, which makes the product inconvenient when using different test tubes; moreover, most blood cell analysis The instruments are set up and sampled vertically, which makes setting out and sampling more difficult, and also increases the probability of blood samples coming into contact with the human body, increasing the risk of needle stick injuries.
