Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0037] During the examination, blood or body fluids need to be dripped into a test tube and the test reagents need to be added and shaken to mix. In order to ensure that the solution is fully mixed and layered, the nurse needs to manually shake the test tube containing blood several times after drawing blood to mix the solution and blood in the tube. This leads to a large workload for nurses, a long treatment time for each patient, and low work efficiency of nurses. In order to solve the above problems.

[0038] The utility model provides a test tube processor.

[0039] See also Figure 1 to Figure 2In one embodiment of the utility model, the test tube processor 100 includes: a shell 1, a limiting component 2 and a driving unit 3, the shell 1 has a cavity 12 with a side opening 11, the side opening 11 is used to take out the test tube, a through hole 13 is provided on the top of the shell 1, the through hole 13 is connected to the cavity 12, and is used to place the test tube; the limiting component 2 is arranged in the cavity 12 corresponding to the through hole 13, and has a limiting area for placing the test tube, the limiting area is located below the through hole 13, the limiting component 2 has a limiting state for limiting the test tube in the limiting area and a releasing state for making the test tube fall off from the limiting area; and the driving unit 3 is arranged in the cavity 12 and is drivingly connected to the limiting component 2, driving the limiting component 2 to shake, so as to vibrate the liquid in the test tube.

[0040] In the technical solution of the utility model, the shell 1 has a cavity 12, and a through hole 13 is provided on the top, and the through hole 13 is connected with the cavity 12. When the nurse uses the test tube processor 100, the test tube is placed into the cavity 12 from the through hole 13. A limiting component 2 is arranged inside the cavity 12, and the limiting component 2 has a limiting area, and the limiting area is directly opposite to the bottom of the through hole 13. The test tube falls from the through hole 13 to the limiting area, and the limiting area is used to place the test tube. The limiting component 2 has two states, one is a limiting state in which the test tube is limited to the limiting area, and the limiting state can be achieved by clamping and fixing the test tube, or making the limiting area at least partially closed, so that the test tube can only move within the limiting area; the other is a release state in which the test tube is released from the limiting area, which can be achieved by opening the clamping claws or opening the closed area. The test tube processor 100 further includes a driving unit 3, which is fixedly connected to the limiting assembly 2. When the test tube is located in the limiting area and the limiting assembly 2 is in the limiting state, the driving unit 3 drives the limiting assembly 2 to shake, thereby causing the liquid in the test tube to vibrate. After the driving unit 3 stops working, the limiting assembly 2 enters the release state again, causing the test tube to fall to the bottom of the cavity 12. The housing 1 is also provided with a side opening 11, from which the shaken test tube can be taken out. Therefore, the test tube processor 100 can replace the nurse to shake the test tube, reduce the labor intensity of the nurse, shorten the time for treating each patient, and improve work efficiency.

[0041] In the method of shaking the liquid in the test tube, reciprocating motion can be performed in a straight line direction to make the liquid oscillate back and forth in this direction, or the limit component 2 can be set on the vibration device. In the first method, the liquid mixing effect is poor, and the time required for uniform mixing is long; setting a vibration device in the cavity 12 will cause the device to be too large, so in this embodiment, the driving part 3 is set to a driving motor 31, and the driving motor 31 includes a motor shaft, and the end of the motor shaft is fixedly connected to the limit component 2. The driving motor 31 rotates, and the limit component 2 rotates around the extension direction of the motor shaft and reciprocates around the axis direction of the motor shaft, such as rotating 45 degrees clockwise around the axis direction of the motor shaft, and then rotating 45 degrees counterclockwise around the axis direction of the motor shaft. Such reciprocating rotation simulates shaking the test tube by hand to ensure the effect of shaking the solution. At the same time, the driving part 3 is only a small driving motor 31, which occupies a small space to reduce the overall volume of the test tube processor 100.

[0042] After the nurse draws blood, the solution in the test tube needs to be shaken to different degrees or not, depending on the completion process of the blood drawing work and the different original base fluids (anticoagulant or procoagulant) in the test tube. In order to meet different needs, multiple through holes 13 are provided, and multiple corresponding limit assemblies 2 and drive motors 31 are provided, and multiple drive motors 31 are respectively connected to multiple limit assemblies 2. The rotation speeds of the multiple drive motors 31 increase successively; and / or the rotation amplitudes of the multiple motor shafts increase successively. So that the drive motor 31 drives the limit assembly 2 to shake to different degrees.

[0043] In order to prevent the test tube from being released at the same position after the shaking of the test tube is completed, the limit assembly 2 will always release the test tube at the same position, resulting in collision and accumulation between the test tubes, and the test tubes will be piled up in the cavity 12 in a disorderly manner. First of all, in order to prevent the subsequent test tubes in the test tube processor 100 from hitting the previous test tubes in the cavity 12 after being released, the position of the limit assembly 2 is required to be different each time it is in the released state. Therefore, the test tube processor 100 also includes a moving assembly 4, and the moving assembly 4 is at least partially movably arranged along the extension direction of the moving assembly 4, and the driving unit 3 is fixedly connected to the movable part of the moving assembly 4. The moving assembly 4 can meet the requirements of being able to perform linear motion and being able to stop at any position on the motion stroke, such as a screw 41 nut 42 mechanism, a gear rack mechanism, etc.

[0044] In order to facilitate the collection of the test tubes after shaking, in one embodiment, the test tube processor 100 also includes a storage box 5, which has a storage cavity 51 with an upper opening for receiving the test tubes, and the storage box 5 can slide out of or into the cavity 12 through the side opening 11 of the shell 1. The storage cavity 51 can be set as one or more. In order to make the test tubes after shaking be arranged neatly, the storage cavity 51 is provided with multiple intervals in the front and back and left and right directions, and each storage cavity 51 is used to place a test tube. After the storage box 5 is pulled out, the test tubes are arranged vertically and neatly, and there is no collision between the test tubes. If the containers (for example: test tubes) do not need to be arranged neatly, and a certain degree of collision between the containers can be accepted, only one storage cavity 51 can be provided for stacking multiple containers.

[0045] In a specific embodiment of the moving assembly 4, the moving assembly 4 further includes: a screw rod 41, a nut 42 and a first motor, wherein the screw rod 41 extends in the left-right direction and is rotatably disposed in the cavity 12; the nut 42 is sleeved on the screw rod 41; the first motor is fixedly connected to the housing 1 and is drivingly connected to the screw rod 41; the first motor drives the nut 42 to move in the extending direction of the screw rod 41, and the nut 42 is fixedly connected to the driving part 3. Since the driving part 3 is fixedly connected to the limiting assembly 2, the rotation of the first motor can drive the driving part 3 and the limiting assembly 2 to move in the left-right direction.

[0046] In a specific embodiment of the limiting assembly 2, the limiting assembly 2 includes: a sleeve 21, a limiting member 22, and a cylinder 23. The sleeve 21 is arranged to penetrate from top to bottom, and the test tube falls from the through hole 13 into the sleeve 21. The sleeve 21 limits the periphery of the test tube, and the limiting member 22 is rotatably connected to one side of the bottom of the sleeve 21; the limiting member 22 can be rotated to the bottom of the sleeve 21 to cover the bottom of the sleeve 21, thereby limiting the bottom of the test tube. Since the driving part 3 only reciprocates slightly, not 360 degrees, the test tube will not fall from the sleeve 21 under the action of gravity. When the driving part 3 is working, the test tube is always located in the sleeve 21 and shakes with the sleeve 21. The cylinder 23 is fixedly connected to the sleeve 21 and is drivingly connected to the limiting member 22, driving the limiting member 22 to rotate to open or close the lower end opening of the sleeve 21.

[0047] In the implementation method of realizing the cylinder 23 controlling the rotation of the limiter 22, specifically, the limiter 22 includes a stopper cover 221, a first rotating part 222, and a second rotating part 223. The stopper cover 221 is used to close the lower end opening of the sleeve 21. The first rotating part 222 is arranged between the stopper cover 221 and the second rotating part 223. The first rotating part 222 is rotatably connected to one side of the bottom of the sleeve 21. The limiter assembly 2 also includes a connecting rod 24. The cylinder 23 has a connecting end movably arranged in the up-down direction. One end of the connecting rod 24 is rotatably connected to the connecting end, and the other end of the connecting rod 24 is rotatably connected to the second rotating part 223. The function of the connecting rod 24 is to convert the linear motion of the connecting end of the cylinder 23 into the rotation of the second rotating part 223, and to control the rotation of the stopper cover 221 with the first rotating part 222 as the fulcrum, so as to cover or open the lower end opening of the sleeve 21.

[0048] In order to achieve disinfection of the solution in the test tube, in one embodiment, the storage box 5 is at least partially transparent, and the test tube processor 100 also includes a plurality of ultraviolet lamps, which are fixedly arranged on the inner circumference of the cavity 12 and irradiated toward the storage box 5 to disinfect and sterilize the test tube in the storage box 5.

[0049] In order to facilitate the inspection and maintenance of the test tube processor 100, in one embodiment, the housing 1 includes a main body and a cover, the upper end of the main body is open, the cover is detachably arranged at the upper end of the main body, and the through hole 13 is arranged on the cover. The connection can be made by direct buckling or threaded connection.
