Abstract

The present invention relates to a medical device and a test tube clamping device for a medical device, including a clamping mechanism. The clamping mechanism includes a first test tube clamping block, a second test tube clamping block and a synchronous shaft. A first clamping opening is arranged inside the first test tube clamping block, and a second clamping opening is arranged inside the second test tube clamping block. The upper parts of the first test tube clamping block and the second test tube clamping block are connected by a telescopic synchronous shaft. In the present invention, the test tube is clamped between the first clamping opening and the second clamping opening, and the test tube cap is located in the space formed by the synchronous shaft, the first clamping opening and the second clamping opening, ensuring that there is no risk of the test tube cap falling off during shaking. At the same time, the synchronous shaft has the function of pressing down the test tube cap to ensure that the test tube cap is tightly closed. Before shaking, the test tube cap will be pressed tightly to prevent the risk of the test tube cap falling off during shaking due to the test tube cap not being tightly closed.

[0059] Among them, the limit block in this embodiment is specifically a limit bearing 231.

[0060] In one embodiment, a medical device is further provided, including the above-mentioned test tube clamping device for medical devices. This medical device applies the above-mentioned test tube clamping device for medical devices, which can improve the degree of automation and work efficiency.

[0061] The working process of the test tube clamping device for medical devices in this embodiment is specifically as follows:

[0062] A test tube cap 6 is provided on the test tube 5;

[0063] The first motor 41 rotates, driving the first lead screw 42 to rotate. The fixed plate 13 moves downward along the first lead screw 42. The first synchronous shaft 191 and the second synchronous shaft 192 press down the test tube cap 6 to ensure that the test tube cap is tightly covered.

[0064] The second motor 21 rotates, driving the second lead screw 22 to rotate. The lead screw nut 28 moves along the second lead screw 22 towards the left end. The lead screw nut 28 drives the transmission block 23 to move towards the left end. The limit bearing 231 moves towards the left end along the inner side of the chute 272. The spring 26 on the fixed shaft 25 pushes the second driving wheel 31 to move towards the left side. The right side plate 18, the second driving wheel 31, and the second driven wheel 32 move towards the left side as a whole. At this time, the first synchronous belt 16 moves, and the first driving wheel 14 rotates, driving the first driven wheel 15 to rotate. The first synchronous belt 16 drives the left side plate 17 to move towards the right side plate 18. The opposite movement of the left side plate 17 and the right side plate 18 enables the first test tube clamping block 11 and the second test tube clamping block 12 to clamp the test tube.

[0065] At this time, the test tube 5 is clamped between the first U-shaped bayonet 111 and the second U-shaped bayonet 121. The test tube cap 6 is located below the first synchronous shaft 191 and the second synchronous shaft 192 in the space formed by the first U-shaped bayonet 111 and the second U-shaped bayonet 121, ensuring that there is no risk of the test tube cap falling off during shaking, that is, the test tube 5 is clamped by the first test tube clamping block 11 and the second test tube clamping block 12.

[0066] When the lead screw nut 28 rotates to the leftmost end, the limit bearing 231 slides out of the chute 272, and the limit piece 24 blocks the lead screw nut 28. The lead screw nut 28 no longer makes a linear motion. The lead screw nut 28, the transmission block 23, and the second lead screw 22 are integrated as a whole and are driven by the second motor 21 to make a rotational motion. The fixed shaft 25 drives the second driving wheel 31 to rotate. The second driving wheel 31 rotates, and the second synchronous belt 33 drives the second driven wheel 32 to rotate. The second driven wheel 32 drives the second connecting shaft 36 to rotate. At this time, the test tube, the first test tube clamping block 11, the second test tube clamping block 12, the first connecting shaft 35, and the second connecting shaft 36 rotate as a whole, thereby realizing the shaking of the blood in the test tube.

[0067] Advantages of this embodiment:

[0068] 1. The structure is simple and compact.

[0069] 2. Before shaking, the test tube cap will be pressed tightly to prevent the risk of the test tube cap falling off during shaking due to the test tube cap not being tightened properly.

[0070] 3. During shaking, the test tube and the test tube cap are firmly fixed to prevent the test tube cap from falling off during the shaking process.

[0071] For the similar parts between the embodiments provided in this application, reference can be made to each other. The specific embodiments provided above are only several examples under the general concept of this application and do not constitute a limitation on the protection scope of this application. For those skilled in the art, any other implementation manner extended based on the solution of this application without creative efforts belongs to the protection scope of this application.
