Problems solved by technology

[0004] However, there are many problems in manual operation. First, the degree and frequency of shaking are different, and the fusion effect of blood and reagents is different. Second, the laboratory department draws a lot of blood every day. It is easy to shake the blood collection tube by waving the arm for a long time and in large quantities. It causes sore arms of medical staff. The third is that after the blood collection tubes are shaken, they need to be inserted into the blood collection tube racks for temporary placement, and then put into a low temperature box for storage, which takes more time and steps. Fourth, the existing blood collection tube racks carry Inconvenient, can not be adjusted according to the actual situation

Embodiment 1

[0063] Such as figure 1 , figure 2 and Figure 19 As shown, a blood collection tube mixing device is characterized in that: it includes a mixing box 1 and a storage module 2, and the mixing box 1 and the storage module 2 are equipped with an expansion bar 102 and an expansion slot 103, and the expansion bar 102 is a horizontal The cross-section is trapezoidal strip shape, and the expansion slot 103 is in the shape of a groove matched with the expansion strip 102, which is convenient for interlocking. The storage module 2 is provided with a plurality of storage holes 201 for storing the blood collection tubes 3 , which is convenient for placing the blood collection tubes 3 .

[0064] In the present application, the extension bars 102 and the extension slots 103 are arranged on both sides of the mixing box 1 respectively, and the extension bars 102 and the extension slots 103 of the storage module 2 are symmetrically distributed on the sides. It can also be adjusted accordin...

Embodiment 2

[0068] In this example, if Figure 4 to Figure 14 As shown, the mixing mechanism includes a first transmission surface 503, a second transmission surface 604, a third transmission surface 901 and a driving surface 401; the button 4 is connected to the driving surface 401 through a spring sleeve rod 402, and the first The driving surface 503 is provided with a driving shaft 601, and one end of the driving shaft 601 is connected with a driving gear 502, and the driving gear 502 is connected with the driving rack 5, and one end of the driving rod 5 passes through the driving surface 401 and the button 4 through the connecting rod 501. The other end is connected with the inside of the mixing box 1 through the spring sleeve rod 402 .

[0069] The other end of the drive shaft 601 passes through the first transmission surface 503 and is connected with the barrel 61 and the amplifying gear 6 . Wherein, the amplifying gear 6 is connected with the drive shaft 601 through a ratchet. Th...

Embodiment 3

[0075] Such as Figure 6 As shown, in this embodiment, the drive rack 5 is connected in a ring shape, the upper and lower surfaces inside the ring are tangent to the drive gear 502 , and a rack portion 504 is provided on one side of the drive rack 5 . Such a structure makes the combination of the driving gear bar 5 and the driving gear 502 more stable, and the vibration of the mechanism is small to avoid tooth skipping.

Abstract

The invention discloses a blood collection tube blending device which comprises a blending box and a storage module, and the blending box and the storage module are each provided with an expansion strip and an expansion groove; a button is arranged on the blending box and connected with an internal uniform mixing mechanism, an opening is formed in the top of the blending box, a test tube rack is arranged at the opening, the two ends of the test tube rack are connected with the inner wall of the blending box and the uniform mixing mechanism through first rotating shafts, through holes for placing a blood collection tube are formed in the test tube rack, and the inner walls of the through holes are made of a rubber material; a plurality of storage holes for storing blood collection tubes are formed in the storage module. The shaking frequency can be adjusted according to the condition of the blood collection tubes or the test tubes, so that the uniform mixing quality of blood and a reagent in the blood collection tubes is ensured, and the accuracy of subsequent experimental data is ensured.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a mixing device for blood collection tubes. Background technique [0002] Blood test is a common method for disease diagnosis and physiological index inspection at present, and vacuum blood collection tube is a necessary blood drawing tool in the blood drawing process. According to different inspection requirements and purposes, there are 9 types of vacuum blood collection tubes, which are distinguished by the color of the blood collection tube cover (red, orange, golden yellow, black, light blue, green, light green, gray and purple) According to the requirements of different assays and data analysis, different chemical reagents are added to different blood collection tubes to achieve the purpose of promoting coagulation, promoting erythrocyte sedimentation, anticoagulation, and inhibiting enolase activity in glucose metabolism. [0003] According to the requirements of the he...
