[0060] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.

[0061] See also Figures 1 to 7 .

[0062] The present application provides a test tube shaking device for medical equipment, comprising a clamping mechanism, a driving mechanism and a shaking mechanism. The clamping mechanism is used to clamp the test tube; the shaking mechanism is used to drive the test tube to rotate; the driving mechanism is used to sequentially stop driving the shaking mechanism to drive the test tube to rotate and then drive the clamping mechanism to release the test tube.

[0063] Specifically, the driving mechanism includes a driving motor and a first transmission assembly and a second transmission assembly driven by the same driving motor. The first transmission assembly is used to drive the shaking mechanism, and the second transmission assembly is used to drive the clamping mechanism.

[0064] The clamping mechanism includes a first test tube clamping block 11, a second test tube clamping block 12, a left plate 13 and a right plate 14.

[0065] The second transmission mechanism includes a second driving wheel 41, a second synchronous belt 43, a second driven wheel 42 and a fixed plate 44. The second driving wheel 41 and the second driven wheel 42 are horizontally arranged on the fixed plate 44, and the second synchronous belt 43 is connected between the second driving wheel 41 and the second driven wheel 42; the left side plate 13 is arranged on the upper part of the second synchronous belt 43, and the right side plate 14 is arranged on the lower part of the second synchronous belt 43.

[0066] The driving mechanism further includes a screw rod 22, which can linearly push one of the first test tube clamping block 11 and the second test tube clamping block 12 to move relative to the other under the drive of the driving motor. When the screw rod 22 can push one of the left plate 13 and the right plate 14 to move relative to the other, the second synchronous belt 43 drives the left plate 13 and the right plate 14 to move toward or away from each other at the same time.

[0067] The first transmission assembly includes a first driving wheel 51, a first driven wheel 52 and a first synchronous belt 53. The first synchronous belt 53 is connected between the first driving wheel 51 and the first driven wheel 52. The first driving wheel 51 is arranged on the upper part of the outer side of the right side plate 14, and the first driven wheel 52 is arranged on the second connecting shaft 32.

[0068] The driving mechanism further comprises a transmission block 23, a screw nut 28, a limit plate 24, a limit block and a mounting block 27. The transmission block 23 is arranged at the far end of the screw 22. At least one fixed shaft 25 is arranged at the far end of the transmission block 23. A stop block is arranged at the far end of the fixed shaft 25. A spring 26 is sleeved on the fixed shaft 25. A first driving wheel 51 has a mounting hole on the side close to the transmission block 23. The first driving wheel 51 is sleeved on the fixed shaft 25 through the mounting hole. The spring 26 is located between the first driving wheel 51 and the transmission block 23. The driving motor is arranged at a side of the fixing plate 44 away from the second driving wheel 41 and the second driven wheel 42. The screw 22 is arranged at the far end of the shaft of the driving motor. The screw nut 28 is threadedly arranged on the screw 22. The transmission block 23 has a through hole. The transmission block 23 is arranged on the outer wall of the screw nut 28 through the through hole. A limit plate 24 is arranged at the far end of the screw 22.

[0069] The limit block is arranged on the outer wall of the transmission block 23, the mounting block 27 is fixed on the fixing plate 44, the mounting block 27 has a fixing hole, the transmission block 23 is located in the fixing hole, the upper part of the mounting block 27 is provided with a slide groove 272 along the length direction of the screw rod 22, the limit block moves in the slide groove 272, the length of the slide groove 272 is equal to the length of the linear motion of the screw nut 28 and the transmission block 23 on the screw rod 22, and an extension portion 271 is extended from the outer side of the mounting block 27 toward the first driving wheel 51.

[0070] The limiting block in this embodiment is specifically a limiting bearing 231 .

[0071] The cooperation between the limit bearing 231 and the slide groove 272 enables the screw nut 28 and the transmission block 23 to rotate relative to the screw 22 and move forward in a straight line for a certain distance when the screw 22 rotates and moves forward in a straight line. This distance is the length of the slide groove, which is exactly the distance of the two left plates 13 and the right plates 14 moving toward each other, and is the preset distance of the screw moving forward in a straight line, just enough to clamp the test tube. When the limit bearing 231 is separated from the slide groove 272, under the fixation of the limit plate 24, the screw nut 28 and the transmission block 23 will rotate with the screw 22 to drive the first driving wheel 52 to rotate, thereby achieving even shaking.

[0072] In one embodiment, a medical device is further provided, including the above-mentioned test tube shaking device for medical equipment. The medical device applies the above-mentioned test tube shaking device for medical equipment to improve the degree of automation and improve work efficiency.

[0073] It should be noted that a test tube cap 7 is provided on the test tube 6 in this embodiment.

[0074] The working process of the test tube shaking device for medical equipment in this embodiment is as follows:

[0075] The motor rotates, driving the screw 22 to rotate, the screw nut 28 moves toward the left end along the screw 22, the screw nut 28 drives the transmission block 23 to move to the left end, the limit bearing 231 moves toward the left end along the slide groove 272, and the spring 26 on the fixed shaft 25 pushes the first driving wheel 51 to move to the left side, and the right side plate 14, the first driving wheel 51 and the first driven wheel 52 move to the left side as a whole. At this time, the second synchronous belt 43 moves, the second driving wheel 41 rotates, driving the second driven wheel 42 to rotate, and the second synchronous belt 43 drives the left side plate 13 to move toward the right side plate 14. The left side plate 1317 and the right side plate 14 move toward each other, so that the first test tube clamping block 11 and the second test tube clamping block 12 clamp the test tube 6;

[0076] When the lead screw nut 28 rotates to the leftmost end, the limit bearing 231 slides out of the slide groove 272, and the limit plate 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 lead screw 22 are integrated into one, and driven by the motor to make a rotational motion. The fixed shaft 25 drives the first driving wheel 51 to rotate, the first driving wheel 51 rotates, the first synchronous belt 53 drives the first driven wheel 52 to rotate, and the first driven wheel 52 drives the second connecting shaft 32 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 31 and the second connecting shaft 32 rotate as a whole, so as to achieve the shaking of the blood in the test tube 6.

[0077] Beneficial effects of this embodiment:

[0078] 1. The test tube is first clamped and then shaken in a sequential motion mode, which effectively prevents the test tube 6 from being shaken when it is not clamped or the clamping mechanism is abnormal, and effectively avoids the test tube 6 from falling or flying off when shaken;

[0079] 2. The two actions of clamping and shaking can be achieved with one drive motor, which effectively reduces the number of motors, reduces enterprise costs, and saves space;

[0080] 3. The left plate 13 and the right plate 14 move toward each other through the push of the spring 26 and the activity of the second synchronous belt 43, and work together to clamp the test tube, thereby ensuring the reliability of the test tube clamping;

[0081] 4. Because a motor is omitted at the test tube clamping position, the back-and-forth movement of the motor harness when achieving the clamping action is effectively reduced, reducing the risk of harness failure due to movement.

[0082] Of course, the first driving wheel 51 can also directly drive the shaking mechanism to rotate, that is, the first transmission assembly includes the first driving wheel 51, the second connecting shaft 32 is arranged on the first driving wheel 51, the first driving wheel 51 is arranged on the outer side of the right side plate 14, and the first driving wheel 51 has a mounting hole on the side close to the transmission block 23. The first driving wheel 51 is sleeved on the fixed shaft 25 through the mounting hole. The spring 26 is located between the first driving wheel 51 and the transmission block 23. The screw rod 22 drives the transmission block 23 to move, and the first driving wheel 51 rotates to drive the shaking mechanism to rotate.

[0083] Similar parts between the embodiments provided in this application can be referenced to each other. The specific implementation methods provided above are only a few 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 methods expanded based on the scheme of this application without creative work belong to the protection scope of this application.
