Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0064] Embodiment 1:

[0065] This embodiment provides a blood shaking and mixing device for blood testing, including an operating table 1 and a shaking and mixing component disposed inside the operating table 1. It further includes: a placing table 4, which is driven to rotate by the shaking and mixing component. A plurality of chutes are radially distributed around the center on the top of the placing table 4; a test tube placing structure, which includes a test tube placing cylinder 7 slidably disposed in the chute, a clamping component disposed in the test tube placing cylinder 7 for clamping the test tube, and a driving component for driving the test tube placing cylinder 7 to move towards the center direction of the placing table 4 or reset; a positioning and supporting structure, which shares the central axis with the placing table 4 and is used to position and support the test tube placing cylinder 7 that moves to the center of the placing table 4. The positioning and supporting structure includes: a support shell 2, which is connected between the placing table 4 and the shaking and mixing component, and the placing table 4, the support shell 2, and the shaking and mixing component share the central axis; a positioning component, which is installed inside the support shell 2 and is used to position the test tube placing cylinder 7 that moves to the center of the placing table 4.

[0066] In this embodiment: Each test tube placement cylinder 7 is in its initial position. A test tube containing blood and anticoagulant is placed in the test tube placement cylinder 7 and clamped by the clamping assembly. The support shell 2 and the placement table 4 are driven by the shaking and mixing assembly to rotate intermittently, so that the test tube placement cylinder 7 and the test tube rotate intermittently, and the blood and anticoagulant in the test tube are shaken and mixed. When it is necessary to take out a certain test tube for observation, the corresponding driving assembly is started to make the test tube placement cylinder 7 move towards the center of the placement table until the test tube placement cylinder 7 moves to the exact center of the placement table. At this time, the positioning assembly positions the test tube placement cylinder 7 to make it stationary, and the clamping assembly cancels the clamping of the test tube, facilitating the extraction of the test tube from the test tube placement cylinder 7 for observation. After the observation is completed, the test tube can be placed back into the test tube placement cylinder 7 again. The driving assembly drives the test tube placement cylinder 7 to return to its original position, and the clamping assembly clamps the test tube again, and the test tube continues to rotate intermittently. After the shaking and mixing is completed, the shaking and mixing assembly is turned off.

[0067] Embodiment 2:

[0068] This embodiment provides a blood shaking and mixing device for blood testing, as Figures 1-4 shown, including an operating table 1. A support shell 2 is rotatably installed in the middle of the top end of the operating table 1. A cavity is opened inside the operating table 1, and a motor 3 is fixedly installed in the cavity. The top of the output shaft of the motor 3 extends outside the cavity and is fixedly connected to the bottom of the support shell 2. A placement table 4 is fixedly installed on the top of the support shell 2. A plurality of sliding grooves 401 are equidistantly and circumferentially opened on the top of the placement table 4, and the plurality of sliding grooves 401 are communicated with each other. Taking this embodiment as an example, six sliding grooves 401 are equidistantly and circumferentially opened on the top of the placement table 4. Each of the sliding grooves 401 is correspondingly provided with a test tube placement cylinder 7. A moving groove 402 communicated with the sliding groove 401 is opened on the bottom wall of the placement table 4. Taking this embodiment as an example, six moving grooves 402 are opened on the bottom wall of the placement table 4. The moving groove 402 extends along the radial direction of the placement table 4. A moving block 5 is slidably installed in the moving groove 402. A connecting plate 6 is fixedly installed on the top of the moving block 5. A test tube placement cylinder 7 is provided on the top of the connecting plate 6. A driving assembly for driving the moving block 5 to move towards the center of the placement table 4 and return to its original position is arranged outside the moving block 5. A round cover 27 is fixedly installed on the top of the operating table 1.

[0069] In this embodiment, during use, place the test tube filled with blood and anticoagulant in the test tube placement cylinder 7. Start the motor 3 to make its output shaft rotate intermittently, thereby driving the support shell 2 and the placement table 4 to rotate intermittently, and further driving the moving block 5, the connecting plate 6 and the test tube placement cylinder 7 to move accordingly, so that the test tube placement cylinder 7 rotates intermittently, enabling the blood and anticoagulant to be shaken and mixed. When it is necessary to take out the test tube for observation, drive the moving block 5 to move towards the center of the placement table 4 through the driving component, thereby driving the connecting plate 6, the test tube placement cylinder 7 and the test tube to move accordingly, so that the test tube continuously moves towards the center of the placement table 4. Finally, the test tube placement cylinder 7 moves to the center of the placement table 4, and the test tube is located at the center of the placement table 4. At this time, the test tube can be drawn out of the test tube placement cylinder 7 for observation. After the observation is completed, the test tube can be placed back into the test tube placement cylinder 7 again. Drive the moving block 5 to drive the connecting plate 6 and the test tube placement cylinder 7 to reset through the driving component, so that the test tube can be taken out, observed and placed back without stopping the rotation of the motor 3, avoiding interrupting the shaking and mixing process.

[0070] Furthermore, it can also be considered in the above embodiment, such as Figure 2 shown, the motor 3 is specifically set as a stepping motor, so that the output shaft of the motor 3 can rotate intermittently.

[0071] Furthermore, it can also be considered in the above embodiment, such as Figure 2 and Figure 4 shown, a round block 22 is fixedly installed in the middle of the bottom end of the test tube placement cylinder 7. The round block 22 is rotatably installed in the middle of the top end of the connecting plate 6. A torsion spring 23 is sleeved outside the round block 22. The two ends of the torsion spring 23 are fixedly connected to the round block 22 and the connecting plate 6 respectively. A positioning component for positioning the round block 22 is provided inside the support shell 2. When the test tube placement cylinder 7 moves to the center of the placement table 4, at this time, the positioning component positions the round block 22, so that the round block 22 cannot rotate and the test tube placement cylinder 7 cannot rotate. At this time, as the placement table 4 rotates, the moving block 5 and the connecting plate 6 continue to rotate and rotate relative to the round block 22. At the same time, the torsion spring 23 is stretched and deformed to generate a force. By positioning the test tube placement cylinder 7, the test tube is positioned and fixed accordingly, making it more convenient to take out the test tube. When the test tube is placed back into the test tube placement cylinder 7, when the moving block 5 resets, the round block 22 and the test tube placement cylinder 7 move accordingly, so that the positioning component cancels the positioning of the round block 22, and the torsion spring 23 releases the force to drive the round block 22 and the test tube placement cylinder 7 to rotate and reset.

[0072] Furthermore, it can also be considered in the above embodiment that the material of the round block 22 is iron.

[0073] Furthermore, it can also be considered in the above embodiment that the positioning component includes:

[0074] The support platform 28 is fixedly installed in the middle of the bottom wall of the support shell 2, and an installation shell 24 is fixedly installed in the middle of the top end of the support platform 28;

[0075] The fixing rod 25 has its bottom extending into the installation shell 24 and is slidably connected to the installation shell 24. A squeezing plate is fixedly installed at the bottom of the fixing rod 25;

[0076] The third spring is located inside the installation shell 24 and is sleeved outside the fixing rod 25;

[0077] The magnet block 26 is fixedly installed at the top of the fixing rod 25, and the magnet block 26 is located at the central position of the central hole.

[0078] As Figure 4 shown, the positioning component includes a support platform 28 fixedly installed in the middle of the bottom wall of the support shell 2. An installation shell 24 is fixedly installed in the middle of the top end of the support platform 28. A fixing rod 25 is slidably installed inside the installation shell 24. A squeezing plate is fixedly installed at the bottom of the fixing rod 25. The top of the fixing rod 25 extends outside the installation shell 24 and is fixedly installed with a magnet block 26. A third spring is sleeved outside the fixing rod 25. The material of the round block 22 is iron. When the round block 22 moves to the center of the placement table 4, the magnet block 26 adsorbs the round block 22, causing the magnet block 26 to rise, thereby driving the fixing rod 25 and the squeezing plate to rise and compress the third spring to deform and generate a force. When the magnet block 26 is adsorbed and fixed to the round block 22, at this time, the round block 22 cannot rotate, achieving its positioning. When the round block 22 moves horizontally and resets, it will be separated from the magnet block 26. At this time, it will leave above the magnet block 26, and the deformed third spring releases the force to drive the squeezing plate, the fixing rod 25 and the magnet block 26 to descend and reset.

[0079] Furthermore, it can also be considered in the above embodiments that the driving component includes:

[0080] Vertical grooves are opened on the inner wall of the support shell 2 and are arranged in one-to-one correspondence with the moving grooves. An iron block 8 is slidably installed in the vertical grooves, and an electromagnet 11 is fixedly installed on the bottom wall of the vertical grooves;

[0081] The wire passing holes 29 penetrate through the bottom wall of the placement table 4 for communicating the moving grooves and the central holes. The wire passing holes are arranged in one-to-one correspondence with the moving grooves. The iron block 8 is connected to the moving block 5 in one-to-one correspondence through a pulling rope 9 passing through the wire passing holes;

[0082] The first spring 10 is located inside the moving groove and is sleeved outside the pulling rope 9.

[0083] As Figures 2-3As shown in the figure, the driving component includes a vertical groove opened on the inner wall of the support shell 2, which is correspondingly arranged with the moving groove. An iron block 8 is slidably installed in the vertical groove, and an electromagnet 11 is fixedly installed on the bottom wall of the vertical groove. A wire passing hole is opened in the middle of the bottom wall of the placing table 4. The iron block 8 is fixedly connected with the moving block 5 through a pulling rope 9 passing through the wire passing hole. A first spring 10 is sleeved outside the pulling rope 9. Start the electromagnet 11 to make it energized and magnetic to attract the iron block 8 to descend, so as to pull the moving block 5 to move towards the center of the placing table 4 through the pulling rope 9, and at the same time compress the first spring 10 to make it deformed to generate a acting force. Finally, the electromagnet 11 adsorbs and fixes with the iron block 8, and the moving block 5 stops moving. At this time, the connecting plate 6 and the test tube placing cylinder 7 above it are located at the exact center of the placing table 4. The electromagnet 11 can be powered off to make it lose magnetism. At this time, the first spring 10 releases the acting force to drive the moving block 5 to reset, so as to pull the iron block 8 to reset through the pulling rope 9, and the reset of the moving block 5 drives the connecting plate 6 and the test tube placing cylinder 7 to reset.

[0084] Furthermore, it can also be considered in the above embodiments that the clamping component includes a bladder 12 fixed on the inner wall of the test tube placing cylinder 7 and a bladder driving component for inflating or deflating the bladder 12, so that the bladder 12 deflates and retracts as the test tube placing cylinder 7 moves towards the center of the placing table 4, and inflates and expands as the test tube placing cylinder 7 resets.

[0085] Furthermore, it can also be considered in the above embodiments that the bladder driving component includes:

[0086] A cylinder block 13, which is fixedly installed on the outside of the placing table 4 and is arranged in one-to-one correspondence with the test tube placing cylinder 7. A piston 14 is arranged inside the cylinder block 13, and a pulling component for driving the piston 14 to move in the vertical direction in a linkage manner with the moving block 5 is arranged outside the piston 14;

[0087] A connecting pipe, which includes a first connecting pipe and a second connecting pipe 15 respectively fixedly installed on the outside of the test tube placing cylinder 7 and the cylinder block 13. The first connecting pipe is communicated with the upper part of the cylinder block 13, the second connecting pipe 15 is communicated with the bladder 12, and the first connecting pipe and the second connecting pipe 15 are communicated through a hose 16.

[0088] Such as Figure 3As shown in the figure, a bladder 12 is fixedly installed on the inner wall of the test tube placement cylinder 7. The inflatable bladder 12 can cooperate to fix the test tube more stably. A cylinder 13 corresponding to the test tube placement cylinder 7 is fixedly installed on the outside of the placement table 4. A piston 14 is provided inside the cylinder 13. A pulling assembly for driving the piston 14 to move in the vertical direction in cooperation with the moving block 5 is provided outside the piston 14. Connecting pipes are fixedly installed on the outside of the test tube placement cylinder 7 and the upper part of the outside of the cylinder 13. The second connecting pipe 15 is communicated with the bladder 12. The first connecting pipe and the second connecting pipe 15 are communicated through a hose 16. When the moving block 5 moves towards the center of the placement table 4, when the moving block 5 is about to stop moving, it will cooperate with the pulling assembly to pull the piston 14 downward, so that the air in the bladder 12 is pumped away through the connecting pipe and the hose 16, making it deflated and losing the stable clamping of the test tube. Finally, when the test tube is located at the center of the placement table 4 and the bladder 12 is deflated to cancel the stable clamping of the test tube, the test tube can be easily taken out and put in. The observed test tube is placed into the deflated bladder 12. When the moving block 5 drives the connecting plate 6 and the test tube placement cylinder 7 to reset, the pulling assembly drives the piston 14 to reset, so that air is injected into the bladder 12 again through the connecting pipe and the hose 16, making it expand, thereby clamping the test tube more stably.

[0089] Furthermore, it can also be considered in the above embodiments that the pulling assembly includes:

[0090] A guide wheel frame, which is fixedly installed at the lower part of the outside of the placement table 4. A guide wheel 17 is rotatably installed in the guide wheel frame, and the guide wheel 17 corresponds to the moving block 5 one by one;

[0091] A pull rod 18, which is fixedly installed on the outside of the moving block 5. A rod passing hole 30 for communicating with the moving groove and allowing the pull rod 18 to pass through is opened on the outer side of the bottom wall of the placement table 4, and the rod passing hole and the moving groove are arranged in one-to-one correspondence;

[0092] A straight rod 19, which is fixedly installed at the bottom of the piston 14, and the bottom end of the straight rod 19 extends outside the cylinder 13;

[0093] A pull wire 20, one end of which is fixedly connected to the straight rod 19, and the other end is fixedly connected to the pull rod 18. The pull wire 20 bypasses the lower part of the guide wheel 17;

[0094] A second spring 21, which is located below the piston 14, and the second spring 21 is sleeved on the outside of the straight rod 19.

[0095] As Figure 3As shown in the figure, the pulling component includes a guide wheel frame fixedly installed at the lower part outside the placing table 4. A guide wheel 17 is rotatably installed inside the guide wheel frame. The guide wheel 17 corresponds to the moving block 5. A pull rod 18 is fixedly installed on the outside of the moving block 5. A straight rod 19 is fixedly installed at the bottom of the piston 14. The bottom end of the straight rod 19 extends outside the cylinder block 13 and is fixedly connected to the pull rod 18 through a wire 20. The wire 20 bypasses the lower part of the guide wheel 17. A second spring 21 is sleeved outside the straight rod 19. The second spring 21 is located below the piston 14. When the moving block 5 moves towards the center of the placing table 4, it will drive the pull rod 18 to move accordingly, thereby pulling the wire 20 to make it continuously straighten. When the moving block 5 is about to stop moving, the moving block 5 cooperates with the pull rod 18 and the straightened wire 20 to pull the straight rod 19 and the piston 14 downwards, and at the same time compress the second spring 21 to make it deform and generate a force. During the process of the moving block 5 resetting, the second spring 21 releases the force to drive the piston 14 to rise.

[0096] Furthermore, it can also be considered in the above embodiments. For example, Figure 3 As shown in the figure, the wire 20 is in a bent state in the initial state, so that when the moving block 5 is about to stop, the wire 20 can be straightened.

[0097] This blood shaking and mixing device can realize the taking out, observing and putting back of test tubes without stopping the rotation of the motor, avoid interrupting the shaking and mixing process, and can cancel the clamping of the test tubes by the bladder while taking out the test tubes without interrupting the shaking and mixing, so that it is convenient to take out the test tubes. When taking out the test tubes, the test tube placing cylinder can be positioned so that it will not continue to rotate, and then it is convenient to take out and put back the test tubes.

[0098] Embodiment 3:

[0099] A blood shaking and mixing method for blood test includes the following steps:

[0100] Step 1: Test tube clamping process

[0101] Each of the test tube placing cylinders 7 is in the initial position. The test tubes filled with blood and anticoagulant are placed in the test tube placing cylinders 7 and clamped by the bladder 12.

[0102] Step 2: Test tube shaking and mixing process

[0103] The shaking and mixing component drives the support shell 2 and the placing table 4 to rotate intermittently, so that the test tube placing cylinders 7 and the test tubes rotate intermittently, and the blood and anticoagulant in the test tubes are shaken and mixed.

[0104] Step 3: Test tube observation process

[0105] When it is necessary to take out a certain test tube for observation, start the corresponding driving component, so that the test tube placing cylinder 7 moves towards the center of the placing table 4 until the test tube placing cylinder 7 moves to the exact center of the placing table 4. At this time, the positioning component positions the test tube placing cylinder 7 to make it stationary, and the bladder 12 retracts to cancel the clamping of the test tube, facilitating the extraction of the test tube from the test tube placing cylinder 7 for observation;

[0106] Step Four: After observation

[0107] The test tube can be placed back into the test tube placing cylinder 7 again. The test tube placing cylinder 7 is driven by the driving component to reset, the bladder 12 expands to clamp the test tube again, and the test tube continues to rotate intermittently;

[0108] Step Five: After shaking and mixing are completed, turn off the shaking and mixing component.

[0109] Working principle: When in use, place the test tube filled with blood and anticoagulant in the test tube placement cylinder 7, start the motor 3 to make its output shaft rotate intermittently, thereby driving the support shell 2 and the placement table 4 to rotate intermittently, and further driving the moving block 5, the connecting plate 6, the round block 22 and the test tube placement cylinder 7 to move accordingly, so that the test tube placement cylinder 7 rotates intermittently, enabling the blood and anticoagulant to be shaken and mixed. When it is necessary to take out the test tube for observation, start the electromagnet 11 to make it energized and magnetic, so that it attracts the iron block 8 to descend, so that the moving block 5 is pulled by the pull rope 9 to move towards the center of the placement table 4, and at the same time compress the first spring 10 to make it deform and generate a force. Finally, the electromagnet 11 adsorbs and fixes the iron block 8, and the moving block 5 stops moving. At this time, the connecting plate 6 and the test tube placement cylinder 7 above it are located at the exact center of the placement table 4. At this time, the test tube can be taken out of the test tube placement cylinder 7 for observation. After the observation is completed, the test tube can be placed back into the test tube placement cylinder 7 again. The electromagnet 11 can be powered off to make it lose magnetism. At this time, the first spring 10 releases the force to drive the moving block 5 to reset, so that the iron block 8 is pulled back by the pull rope 9. The reset of the moving block 5 drives the connecting plate 6 and the test tube placement cylinder 7 to reset, enabling the test tube to be taken out, observed and placed back without stopping the rotation of the motor 3, avoiding interrupting the shaking and mixing. When the moving block 5 moves towards the center of the placement table 4, it will drive the pull rod 18 to move accordingly, thereby pulling the pull wire 20 to make it continuously straighten. When the moving block 5 is about to stop moving, the moving block 5 cooperates with the pull rod 18 and the straightened pull wire 20 to pull the straight rod 19 and the piston 14 to descend, and at the same time compress the second spring 21 to make it deform and generate a force, so that the air in the bladder 12 is pumped away through the connecting pipe and the hose 16 to make it deflate and lose the stable clamping of the test tube. Finally, when the test tube is located at the center of the placement table 4 and the bladder 12 deflates to cancel the stable clamping of the test tube, the test tube can be easily taken out and put in. When the moving block 5 drives the connecting plate 6 and the test tube placement cylinder 7 to reset, the second spring 21 releases the force to drive the piston 14 to rise, so that the piston 14 is driven to reset, so that the air is injected into the bladder 12 again through the connecting pipe and the hose 16 to make it expand, thereby clamping the test tube more stably. When the round block 22 moves to the center of the placement table 4, the magnet block 26 adsorbs the round block 22 to make the magnet block 26 rise, thereby driving the fixed rod 25 and the extrusion plate to rise accordingly and compress the third spring to make it deform and generate a force. When the magnet block 26 adsorbs and fixes the round block 22, the round block 22 cannot rotate at this time, realizing its positioning. At this time, as the placement table 4 rotates, the moving block 5 and the connecting plate 6 continue to rotate so that they rotate relative to the round block 22. At the same time, the torsion spring 23 is pulled and deformed to generate a force. Through the positioning of the test tube placement cylinder 7, the test tube is positioned and does not move, enabling the test tube to be taken out more conveniently. After the test tube is placed back into the test tube placement cylinder 7, when the moving block 5 resets, the round block 22 and the test tube placement cylinder 7 move accordingly. When the round block 22 moves horizontally and resets, it will be separated from the magnet block 26, and at this time it will leave above the magnet block 26.The deformed third spring releases the acting force to drive the extrusion plate, the fixing rod 25 and the magnet block 26 to descend and reset. The torsion spring 23 releases the acting force to drive the round block 22 and the test tube placement cylinder 7 to rotate and reset. After that, the motor 3 can be turned off.
