Description

Technical Field

[0001] This application relates to the field of blood braid pipetting technology, and more particularly to a blood braid pipetting device. Background Technology

[0002] A blood braid is a sample tube attached to a blood bag. After blood collection, a section of the blood braid is usually cut off, and the blood in that section is transferred to a test tube as a sample for testing the blood in the bag.

When cutting, the scissors exert shearing and squeezing force on the blood braid tube, which can cause blood to splash easily. This not only contaminates and endangers the operator, but also easily causes cross-contamination between blood samples. Summary of the Invention

[0024] like Figure 1 and 3 As shown, an embodiment of this application provides a braided pipetting device 100, mainly used to transfer blood samples from a braid into a test tube. The braided pipetting device 100 includes a sliding seat 111, a first clamping mechanism 112, a squeezing mechanism 113, and a flow-stopping mechanism 114.

[0025] The first clamping mechanism 112 is disposed on the sliding seat 111 and includes a first driving component 1121 and a first clamping component 1122. The first driving component 1121 is engaged with the first clamping component 1122 and is used to drive the first clamping component 1122 to clamp or release the braided tubing.

[0026] The squeezing mechanism 113 is disposed on the sliding seat 111 and includes a second driving component 1131 and a second clamping component 1132. The second driving component 1131 is engaged with the second clamping component 1132 and is used to drive the second clamping component 1132 to clamp or release the blood braided tubing.

[0027] The flow-stopping mechanism 114 is disposed on the sliding seat 111 and includes a third drive assembly 1141 and a third clamping assembly 1142. The third drive assembly 1141 is engaged with the third clamping assembly 1142 and is used to drive the third clamping assembly 1142 to clamp or release the blood braided tubing. The third clamping assembly 1142 is located between the first clamping assembly 1122 and the second clamping assembly 1132.

[0028] In the embodiment of this application, the braided pipetting device 100 is operated by a first driving component 1121 first driving the first clamping component 1122 to clamp and fix the braided tubing through a meshing connection. After the first clamping component 1122 clamps and fixes the braided tubing, the second driving component 1131 then drives the second clamping component 1132 to clamp and squeeze the braided tubing through a meshing connection, so as to squeeze out the blood sample at the end of the braided tubing and make the blood sample at the end of the braided tubing flow to the middle section of the braided tubing.

[0029] After the second clamping component 1132 clamps and squeezes the braided tubing, the third driving component 1141 then drives the third clamping component 1142 located between the first clamping component 1122 and the second clamping component 1132 to clamp the stop-flow braided tubing through a meshing connection, so as to stop the flow and prevent the blood sample in the middle section of the braided tubing from flowing to the end of the braided tubing.

[0030] After the third clamping component 1142 clamps the stop-flow braided tubing, the second driving component 1131 then drives the second clamping component 1132 to release the end of the braided tubing through a meshing connection, so as to cut off the end of the braided tubing corresponding to the position of the second clamping component 1132.

[0031] The braided pipetting device 100 provided in this application effectively prevents blood sample splashing when cutting the end of the braided tubing because the blood sample at the end of the braided tubing is emptied and the blood sample is kept in the middle section of the braided tubing under the clamping and flow-stopping action of the third clamping component 1142. This avoids contamination and harm to the operator and cross-contamination between different blood samples.

[0032] For example, the first drive assembly 1121, the second drive assembly 1131 and the third drive assembly 1141 can all be servo motors, and the first clamping assembly 1122, the second clamping assembly 1132 and the third clamping assembly 1142 can all be grippers, with toothed portions on the grippers that mesh with the gears of the servo motors.

[0033] like Figure 1 and Figure 3 As shown, in one embodiment of this application, the blood pipetting device 100 further includes a second clamping mechanism 115. The second clamping mechanism 115 is disposed on the sliding seat 111. The second clamping mechanism 115 includes a fourth driving component 1151 and a fourth clamping component 1152. The fourth driving component 1151 is engaged with the fourth clamping component 1152 and is used to drive the fourth clamping component 1152 to clamp or release the test tube. The fourth clamping component 1152 is located on the side of the second clamping component 1132 away from the first clamping component 1122.

[0034] In this embodiment, after the end of the braided tubing is cut, the fourth driving component 1151 first drives the fourth clamping component 1152, located on the side of the second clamping component 1132 away from the first clamping component 1122, to clamp and fix the test tube through an engaging connection. Then, the third driving component 1141 drives the third clamping component 1142 to release the braided tubing through an engaging connection, thereby invalidating the flow-stopping effect and allowing the blood sample in the middle section of the braided tubing to flow into the test tube under its own gravity, thus completing the braided pipetting.

[0035] For example, the fourth drive assembly 1151 can be a servo motor, and the fourth clamping assembly 1152 can be a gripper with teeth that mesh with the gears of the servo motor.

[0036] like Figure 1 and Figure 3 As shown in the above embodiments of this application, the blood braid pipetting device 100 further includes a weighing device 116, which is disposed on the sliding seat 111, and a second clamping mechanism 115 is disposed on the weighing device 116. The weighing device 116 is used to weigh the blood sample transferred from the blood braid tubing to the test tube.

[0037] In this embodiment, by setting a weighing device 116 on the sliding seat 111 and setting a second clamping mechanism 115 on the weighing device 116, the weighing device 116 can weigh the blood sample after the blood sample in the braided tubing is transferred to the test tube, thus realizing the function of weighing the blood sample.

[0038] For example, the weighing device 116 may include a support and a weighing sensor, with the weighing sensor disposed on the sliding seat 111, the support disposed on the weighing sensor, and the second clamping mechanism 115 disposed on the support.

[0039] like Figure 1 and Figure 3 As shown in the above embodiments of this application, the blood pipetting device 100 further includes a mounting base 117 and a fifth drive assembly 118. The fifth drive assembly 118 includes a first drive member 1181 and a first drive wheel 1182. The first drive member 1181 is disposed on the mounting base 117, and the first drive wheel 1182 is fixedly connected to the output end of the first drive member 1181. The sliding seat 111 is engaged with the first drive wheel 1182 and slidably connected to the mounting base 117.

[0040] In this embodiment, the first drive wheel 1182 is fixedly connected to the output end of the first drive member 1181 so as to rotate synchronously and stably with the output end of the first drive member 1181. By engaging the sliding seat 111 with the first drive wheel 1182 and sliding it with the mounting seat 117, the sliding seat 111 is driven to reciprocate linearly on the mounting seat 117 under the action of engagement, thereby adjusting the positions of the first clamping mechanism 112, the squeezing mechanism 113, the flow-stopping mechanism 114 and the second clamping mechanism 115 on the sliding seat 111, thereby adapting to different blood braided tubing lengths and effectively expanding the applicability of the blood braided pipetting device 100.

[0041] For example, the first drive wheel 1182 is provided with a gear part 11821, and the sliding seat 111 is provided with a rack part 1111 that meshes with the gear part 11821. The first drive member 1181 can be a rotary motor.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown in the above embodiments of this application, the blood pipetting device 100 further includes a first sliding frame 121 and a flipping mechanism 122. The flipping mechanism 122 includes a swing member 1221 and a sixth drive assembly 1222. The swing member 1221 is rotatably connected to the first sliding frame 121. The sixth drive assembly 1222 is disposed on the first sliding frame 121 and connected to the swing member 1221, and is used to drive the swing member 1221 to rotate relative to the first sliding frame 121. The mounting base 117 is disposed on the swing member 1221.

[0043] In this embodiment, the swing member 1221 is rotatably connected to the first sliding frame 121. By setting the sixth driving component 1222 on the first sliding frame 121 and connecting it to the swing member 1221, the swing member 1221 is driven to rotate relative to the first sliding frame 121, thereby causing the mounting base 117 set on the swing member 1221 to rotate synchronously. This achieves the flipping function of the first clamping mechanism 112, the squeezing mechanism 113, the flow-stopping mechanism 114, and the second clamping mechanism 115. The flipping mechanism is set to a horizontal state so that the shearing mechanism 154 can cut the end of the braided tubing. The flipping mechanism is set to a vertical state so that the blood sample in the braided tubing can flow into the test tube under its own gravity.

[0044] For example, the sixth drive assembly 1222 may consist of a rotary motor and a synchronous pulley. The sixth drive assembly 1222 may also be a cylinder, a hydraulic cylinder or a linear push rod motor, which drives the swing member 1221 to rotate relative to the first sliding frame 121 through linear extension and retraction.

[0045] like Figure 1 and Figure 2As shown in the above embodiments of this application, the blood pipetting device 100 further includes a first linear movement mechanism. The first linear movement mechanism includes a second sliding frame 131 and a seventh drive assembly 132. The first sliding frame 121 is slidably connected to the second sliding frame 131. The seventh drive assembly 132 is disposed on the second sliding frame 131 and connected to the first sliding frame 121, and is used to drive the first sliding frame 121 to slide along the second sliding frame 131.

[0046] In this embodiment, the first sliding frame 121 and the second sliding frame 131 are slidably connected. By setting the seventh driving component 132 on the second sliding frame 131 and connecting it to the first sliding frame 121, the first sliding frame 121 is driven to reciprocate linearly relative to the first sliding frame 121 on the second sliding frame 131. This drives the flipping mechanism 122, the mounting base 117, the first clamping mechanism 112, the squeezing mechanism 113, the flow-stopping mechanism 114, and the second clamping mechanism 115 to reciprocate linearly relative to the first sliding frame 121, thereby realizing the lifting and lowering movement functions of the first sliding frame 121, the flipping mechanism 122, the mounting base 117, the first clamping mechanism 112, the squeezing mechanism 113, the flow-stopping mechanism 114, and the second clamping mechanism 115.

[0047] For example, the seventh drive assembly 132 may consist of a rotary motor and a synchronous pulley. The seventh drive assembly 132 may also be a cylinder, a hydraulic cylinder or a linear push rod motor, which drives the first sliding frame 121 to reciprocate linearly relative to the first sliding frame 121 on the second sliding frame 131 through linear extension and retraction.

[0048] like Figure 1 and Figure 2 As shown in the above embodiments of this application, the blood pipetting device 100 further includes a second linear movement mechanism. The second linear movement mechanism includes a first frame 141 and an eighth drive assembly 142. The second sliding frame 131 is slidably connected to the first frame 141. The eighth drive assembly 142 is disposed on the first frame 141 and connected to the second sliding frame 131, and is used to drive the second sliding frame 131 to slide along the first frame 141.

[0049] In this embodiment, the second sliding frame 131 is slidably connected to the first frame 141. By setting the eighth drive assembly 142 on the first frame 141 and connecting it to the second sliding frame 131, the second sliding frame 131 is driven to reciprocate linearly relative to the first frame 141. This drives the seventh drive assembly 132, the first sliding frame 121, the flipping mechanism 122, the mounting base 117, the first clamping mechanism 112, the squeezing mechanism 113, the flow-stopping mechanism 114, and the second clamping mechanism 115 to reciprocate linearly relative to the first frame 141 simultaneously, thereby realizing the forward and backward movement function of the second sliding frame 131, the seventh drive assembly 132, the first sliding frame 121, the flipping mechanism 122, the mounting base 117, the first clamping mechanism 112, the squeezing mechanism 113, the flow-stopping mechanism 114, and the second clamping mechanism 115.

[0050] For example, the eighth drive assembly 142 may consist of a rotary motor and a synchronous pulley. The eighth drive assembly 142 may also be a cylinder, a hydraulic cylinder or a linear push rod motor, which drives the second sliding frame 131 to reciprocate linearly relative to the first frame 141 on the first frame 141 through linear extension and retraction.

[0051] like Figure 1 and Figure 2 As shown, in any of the above embodiments of this application, the blood pipetting device 100 further includes a third linear movement mechanism. The third linear movement mechanism includes a second frame 151, a third sliding frame 152, and a ninth drive assembly 153. The third sliding frame 152 is slidably connected to the second frame 151. The ninth drive assembly 153 is disposed on the second frame 151 and connected to the third sliding frame 152, and is used to drive the third sliding frame 152 to slide along the second frame 151.

[0052] In this embodiment, the third sliding frame 152 is slidably connected to the second frame 151. By setting the ninth driving component 153 on the second frame 151 and connecting it to the third sliding frame 152, the third sliding frame 152 is driven to reciprocate linearly relative to the second frame 151 on the second frame 151, thereby realizing the left and right movement function of the third sliding frame 152.

[0053] For example, the ninth drive assembly 153 may consist of a rotary motor and a synchronous pulley. The ninth drive assembly 153 may also be a cylinder, a hydraulic cylinder or a linear push rod motor, which drives the third sliding frame 152 to reciprocate linearly relative to the second frame 151 on the second frame 151 through linear extension and retraction.

[0054] like Figure 1 and Figure 2As shown in the above embodiments of this application, the blood braid pipetting device 100 further includes a shearing mechanism 154, which is disposed on the third sliding frame 152. The shearing mechanism 154 includes a tenth driving component 1541 and a shearing component 1542. The tenth driving component 1541 is engaged with the shearing component 1542 to drive the shearing component 1542 to shear the blood braid tubing.

[0055] In this embodiment, by setting the shearing mechanism 154 on the third sliding frame 152, it can reciprocate linearly relative to the second frame 151 in sync with the third sliding frame 152, thereby realizing the left and right movement function of the shearing mechanism 154 and adjusting the shearing position of the shearing mechanism 154 relative to the braided tube.

[0056] For example, the tenth drive assembly 1541 can be a servo motor, and the shearing assembly 1542 can be scissors with toothed portions that mesh with the gears of the servo motor.
