Automatic loading mechanism of fully automatic coagulation analyzer

Abstract

The present invention provides an automatic loading mechanism of a fully automatic coagulation analyzer. A positioning mechanism is arranged under a disc mechanism, so that the positioning precision is greatly improved; a stepping motor is used to control an eccentric block, and a positioning link is connected to control the movement of a positioning sleeve; a piston structure is formed between the positioning sleeve and an annular cushion, and the rise and fall time of the positioning link is short, so that the time for falling into the disc is greatly saved; the loading and unloading work ofthe test disc is completed by using the loading mechanism, the height of the mechanical arm in the Z direction is completed by using the screw motor, and by using the drive motor and the belt drive to realize the rotation of the mechanical arm, angle adjustment between the mechanical arm and the test disc is completed to prepare for the gripping action, so that the whole operation process is simple and convenient; opening and closing of the first mechanical arm and the second mechanical arm are adjusted by using the electromagnet and the electromagnet rod, so that the clamping and loosening of the test disc can be completed; and the cooperation of the ball stud and the circular arc groove ensures that the test disc can be smoothly loaded.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an automatic loading mechanism of a fully automatic coagulation analyzer. Background technique [0002] Thrombosis and hemostasis are one of the important functions of blood. The formation and regulation of thrombus and hemostasis constitute the complex and functionally opposite coagulation system and anticoagulation system in blood. They maintain a dynamic balance through the regulation of various coagulation factors, making Under physiological conditions, blood maintains a normal fluid state, neither overflowing outside the blood vessel nor coagulating in the blood vessel. The purpose of the hemostasis and thrombus test is to understand the cause and pathological process from different aspects and links through the detection of various coagulation factors, and then to diagnose and treat the disease. The coagulation analyzer is a special instrument for the analysis of t...

AI Technical Summary

Problems solved by technology

The coagulation analyzer uses a test disc to perform coagulation tests. The test disc loading mechanism is an important part of the coagulation analyzer. The test disc loading mechanism includes a drop mechanism and a gripper mechanism, but there are the following problems: First, when using the drop mechanism, There are certain precision requirements for the falling posture of the test disc, and there should be no large position deviation when the test disc falls

However, the deviation of the test disk will occur in the existing plate-loading mechanism, which will affect the grasping of the test disk; the second is that the existing gripper mechanism is generally complicated in structure and inconvenient to use, and cannot meet the needs of people to use the gripper to load the test disk. need
