Embodiment 1

[0035] see Figure 4-5 , the present invention provides a coagulation analyzer, including a grab cup system 100, wherein the grab cup system 100 includes a magnetic bead analysis cup 10, an optical cup 20, and a handle mechanism 30, and the grip mechanism 30 can grab the magnetic bead analysis cup 10 or optical cup 20.

[0036] A blood coagulation analyzer provided by the present invention has the analysis of both the magnetic bead method and the optical method. The blood coagulation analyzer only needs to be equipped with a set of grabbing cup system 100 to realize grabbing the magnetic bead analysis cup 10 or the optical cup 20. The control process of the cup system 100 is simple, the overall instrument structure is simple, and the volume is small and exquisite.

Embodiment 2

[0038] see Image 6 The gripper mechanism 30 includes a mounting part 301, a grasping finger 302 movably arranged on the mounting part 301 and an elastic member 303 connected to the grasping finger 302, and the grasping finger 302 arranged oppositely forms a protrusion for grasping the following The elastic member 303 provides a tightening pre-tightening force to the oppositely disposed grasping fingers 302 . Two pieces of grasping fingers 302 are arranged oppositely to form a grasping part to grasp the magnetic bead analysis cup 10 or optical cup 20, and the oppositely disposed grasping fingers 302 are connected by an elastic member 303, so that the grasping fingers 302 are not grasping the magnetic beads. The front of the bead analysis cup 10 or the optical cup 20 is in a tightened state. When the magnetic bead analysis cup 10 or the optical cup 20 needs to be grasped, the magnetic bead analysis cup 10 or the optical cup 20 is snapped into between the grasping fingers 302 ar...

Embodiment 3

[0041] see Figure 1-3The magnetic bead analysis cup 10 includes a cup body 1, the cup bottom of the cup body 1 is provided with an arc 11 for magnetically driven particles to roll back and forth, and the cup body 1 is provided with a gripper mechanism 30 for grabbing the cup system 100. The part to be clamped 12 is taken, and the part to be clamped 12 includes a protruding part 121 adapted to the grasping part of the above-mentioned grasping cup system.

[0042] An arc track 11 is provided at the bottom of the cup body 1 for the magnetic bead analysis cup 10 to be used for magnetically driven particles to roll in the arc track 11 to realize the analysis of samples. The gripper mechanism 30 of the system 100 grasps the portion to be gripped 12, the portion to be gripped 12 can be set independently and is not limited to the cup body of the magnetic bead analysis cup, further, the portion to be gripped 12 is set with the gripping cup system The protruding part 121 that fits the...

Abstract

The invention is applicable to the technical field of medical instruments, and provides a magnetic bead analysis cup, a cup grabbing system and method and a coagulation analyzer. The magnetic bead analysis cup is used for a cup grabbing system which is used in cooperation with an optical cup, and comprises a cup body, the bottom of the cup body is provided with an arc channel in which particles can be driven by a magnetic force to roll back and forth, the cup body is provided with a to-be-clamped part which is grabbed by the cup grabbing system, and the to-be-clamped part includes a protrudingpart matching a grabbing part of the cup grabbing system. The magnetic bead analysis cup and the optical cup can match the same cup grabbing system, an original specific cup grabbing system of the magnetic bead analysis cup can be omitted, the structure of the coagulation analyzer is simplified, control of the cup grabbing system is less complex, and the fault rate is reduced; and in addition, the magnetic bead analysis cup is low in production cost, easier to process and product and capable of batch production.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a magnetic bead analysis cup, a cup grasping system, a blood coagulation analyzer and a cup grasping method. Background technique [0002] With the development of medical equipment and biotechnology, the basic theory of hemostasis and thrombus and its application are increasingly advanced, and the automatic coagulation analyzer is rapidly developed and applied to the diagnosis and treatment process. [0003] The magnetic bead method and optical method in the coagulation test method, the optical method is the current mainstream in the market, but when the blood coagulation test is performed, when there are hemolysis, jaundice, blood lipids and other interfering substances in the sample, the measurement results of the optical method will be affected. The magnetic bead method uses magnetic force to drive the demagnetized steel balls to move in the sample. When th...
