Problems solved by technology

[0008] The purpose of the present invention is to provide a method that can ensure the avoidance of jamming in the working process, aiming at the disadvantages of the current analyzer that the sample loading arm is prone to jamming, resulting in reduced lifting accuracy, shortened service life, and limited rotation angle. The resistance phenomenon ensures the lifting accuracy and the smoothness of the lifting, and the sampling device with unlimited rotation angle

Embodiment 1

[0044] Example 1, such as figure 1 , as shown in 2 and 3,

[0045] A guide sleeve, comprising:

[0046] - Shaft sleeve 1: the shaft sleeve 1 is sleeved on the spline shaft 2 of the sample loading arm, and the inner wall of the shaft sleeve 1 is provided with a protrusion 3 that matches the keyway 8 of the spline shaft 2. The spline shaft 2 can slide along the inner wall of the sleeve 1;

[0047] - Locking sleeve 4: the locking sleeve 4 is sleeved on the outside of the shaft sleeve 1, and the locking sleeve 4 is arranged on the frame 10 of the sample loading arm through the first rotating part 5, so that the locking The sleeve 4 can rotate around its axial direction;

[0048] - Transmission part 6: the transmission part 6 is connected between the locking sleeve 4 and the rotary driving device 7 of the sample loading arm, so that the rotary driving device 7 can drive the locking sleeve 4 to rotate.

[0049]In the above scheme of this embodiment, the cooperation between the s...

Embodiment 2

[0050] Example 2, such as figure 1 , as shown in 2 and 3, as the guide sleeve shown in embodiment 1,

[0051] The locking sleeve 4 is also provided with a first locking member 9, the relative position of the first locking member 9 and the locking sleeve 4 is fixed, and the first locking member 9 locks the locking sleeve 4 is constrained on the frame 10 and restricts the axial movement of the locking sleeve 4 along the spline shaft 2, the first rotating part 5 includes two bearings, and the two bearings are separated It is provided that the inner ring of the bearing cooperates with the locking sleeve 4 , and the outer ring of the bearing cooperates with the frame 10 .

[0052] In the above solution of this embodiment, by setting the first locking member 9, the guide sleeve of this embodiment is arranged on the base frame, but the rotation of the guide sleeve is not restricted, thereby ensuring the rotation of the spline shaft 2 ; By setting two bearings as the first rotating ...

Embodiment 3

[0053] Example 3, such as figure 1 , as shown in 2 and 3, as the guide sleeve shown in embodiment 2,

[0054] The transmission part 6 includes a synchronous pulley 11 and a synchronous belt 12 matched with the synchronous pulley 11, the synchronous pulley 11 is coaxially fixedly connected with the locking sleeve 4, and the rotary drive device 7 is Rotary motor, the synchronous pulley 11 and the rotary motor are connected through the synchronous belt 12, the frame 10 is provided with a first photoelectric switch 13, and the first locking member 9 is provided with The horizontal reset photoelectric barrier 14 matched with the first photoelectric switch 13, when the rotary drive device 7 drives the locking sleeve 4 to rotate to a limited position, the horizontal reset photoelectric barrier 14 and the first photoelectric switch 13 Correspondingly, the first photoelectric switch 13 controls the rotary driving device 7 to stop or reverse.

Abstract

The invention relates to the technical field of medical devices, in particular to a guide sleeve and a sample loading arm and an analyzer using the guide sleeve, including: a shaft sleeve: the shaft sleeve is set on a spline shaft of the sample loading arm, and the shaft The inner wall of the sleeve is provided with a protrusion matching the keyway of the spline shaft, and the spline shaft can slide along the inner wall of the sleeve; locking sleeve: the locking sleeve is sleeved outside the sleeve, so that The locking sleeve is arranged on the frame of the sample loading arm through the first rotating part, so that the locking sleeve can rotate around its axial direction; transmission part: the transmission part is connected to the locking sleeve and the sample loading arm Between the rotary drive device, the rotary drive device can drive the locking sleeve to rotate. In the above solution of the present application, the smoothness of lifting and lowering of the spline shaft and the accuracy of lifting are guaranteed, and the service life thereof is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a guide sleeve, a sample loading arm and an analyzer using the guide sleeve. Background technique [0002] With the development of society, people pay more and more attention to the problems of physical health and disease treatment. How to accurately diagnose and evaluate the physical condition has become the decisive basis for measuring health status and diagnosis and treatment. [0003] Among the diagnostic methods, in vitro diagnosis is currently an important diagnostic method, which is aimed at the quantitative detection of disease-related trace substances in the human body, especially for the diagnosis and treatment of major infectious diseases, cancer, diabetes and other diseases. [0004] For the sample analyzer, the process of adding samples, adding reagents, mixing, cleaning and testing in the detection is realized through the spatial displacement of the reaction...
