Description

Technical Field

[0001] The present invention relates to the technical field of blood mixing, and in particular to a blood mixing device. Background Art

[0002] In the medical field, collecting blood samples is one of the important steps for various diagnoses and tests. Traditionally, blood needs to be mixed immediately after blood collection. The mixing technique of the blood collection tube is to gently or invert the blood collection tube containing additives 6 to 8 times immediately after blood collection. The number of mixing times should be in accordance with the requirements of the product manual. Repeated slow inversion and shaking will make the blood collection work of medical staff cumbersome and time-consuming when a large amount of blood is collected in the laboratory. In addition, the workload of medical staff is large. If the inversion is not balanced enough, the added reagents and blood are not fully integrated, which can easily lead to blood coagulation. Inversion with too much force can also easily cause hemolysis. After blood collection, the test tube is inverted and shaken. If the staff repeatedly inverts and shakes in this way for a long time, it is easy to cause damage to the wrist joint ligament of the staff, and get occupational diseases such as tenosynovitis and carpal tunnel inflammation.

[0003] Therefore, we need to use a mixing and shaking device; for example, the patent with announcement number CN218422391U discloses a portable blood mixing rocker, which is composed of a bottom plate, a suction nozzle fixed at the four corners of the bottom of the bottom plate, and a support plate fixed at the front and rear ends of the top of the bottom plate. The driving component fixed on the outside of the front support plate can control the rotation of the rotating component transferred between two support plates, and the cover body fixed on the outside of the front support plate can isolate the driving component from the outside. The utility model can first fix the position of the placed test tube, and then through the effect of the swing function, the device drives the test tube containing blood to swing back and forth left and right, and then shake the blood in the test tube evenly, reducing the workload of medical staff.

[0004] However, when the device is used to fix the test tube, the test tube is first placed in the placement sleeve, and then the test tube is fixed by rotating the threaded rod. Therefore, the existing mixing and shaking device often requires multiple steps when fixing the test tube, which greatly wastes the time of blood collection when the amount of blood collected is large. Summary of the invention

[0005] In view of the above problems existing in the prior art, the technical problem to be solved by the present invention is that the existing mixing and shaking device often requires multiple steps when fixing the test tube, which greatly wastes the time of blood collection when the amount of blood collected is large.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solution: a blood mixing device, comprising:

[0007] The installation body is provided with a blind pipe hole for accommodating the test tube;

[0008] A clamping mechanism, comprising: a clamping member, a friction member and an elastic member; the middle portion of the clamping member is hinged to the inner side wall of the blind hole of the pipeline; the friction member is fixedly mounted on one end of the clamping member close to the opening end of the blind hole of the pipeline and is located on the side of the clamping member close to the axis of the blind hole of the pipeline; the elastic member applies a torsional force to the clamping member to push the end of the clamping member close to the opening end of the blind hole of the pipeline to rotate in a direction away from the axis of the blind hole of the pipeline, and push the end of the clamping member close to the closed end of the blind hole of the pipeline to rotate in a direction close to the axis of the blind hole of the pipeline; and

[0009] The mixing and shaking mechanism can shake the installation body.

[0010] Preferably, the clamping mechanisms are arranged in a plurality in a circular array with the axis of the pipeline blind hole as the center.

[0011] Preferably, it also includes a fixing mechanism, which includes: a sliding seat, a pull rope and a one-way channel; the sliding seat is arranged in the blind hole of the pipeline and slidably cooperates with the blind hole of the pipeline; the end of the sliding seat close to the opening end of the blind hole of the pipeline is provided with a groove that cooperates with the bottom end of the test tube; the sliding seat is also provided with a through hole connecting the two sides of the sliding seat, and the end of the through hole close to the opening end of the blind hole of the pipeline is located in the groove; one end of the pull rope is fixedly mounted on the sliding seat, and the other end of the pull rope is fixedly mounted on the end of the clamp close to the closed end of the blind hole of the pipeline; a one-way channel is provided on the mounting body, one end of the one-way channel is connected to the outside world, and the other end of the one-way channel is connected to the closed end of the blind hole of the pipeline, and the one-way channel is connected in one direction toward the outside world.

[0012] Preferably, a rubber ring is sleeved on the outer side of the slide seat.

[0013] Preferably, a rubber gasket is installed in the groove.

[0014] Preferably, a roller is installed at one end of the clamping member close to the pulling end.

[0015] Preferably, the friction member is made of rubber.

[0016] Preferably, the elastic member is a torsion spring.

[0017] Preferably, the mixing mechanism comprises: a frame, a rotating shaft and a motor; the mounting body is rotatably mounted on the frame via the rotating shaft, and the rotating shaft is arranged perpendicular to the axis of the blind hole of the pipeline; the motor can rotate by driving the mounting body.

[0018] Compared with the prior art, the present invention has at least the following advantages:

[0019] 1. In the present invention, the test tube after blood collection is inserted into the blind hole of the pipeline, so that the bottom end of the test tube abuts against the inclined friction member. In the process of the test tube moving downward, the torsion of the elastic member on the clamping member is overcome, and the end of the clamping member close to the closed end of the blind hole of the pipeline is pushed to rotate outward, and the end of the clamping member close to the open end of the blind hole of the pipeline is rotated inward, so that the clamping frame can be driven to abut, and the test tube is clamped in cooperation with the inner wall of the blind hole of the pipeline; for this reason, only one step of inserting the test tube into the blind hole of the pipeline is required to achieve the clamping of the test tube; the process of clamping the test tube is greatly simplified.

[0020] 2. In the present invention, the test tube can be clamped for a second time through the setting of the fixing mechanism, and the slide seat can be pushed by the test tube. Under the action of negative pressure, the friction force between the friction part and the test tube can be fixed, which greatly ensures the stability of the clamping mechanism on the test tube, so as to reduce the probability of the test tube slipping out during mixing.

[0021] 3. In the present invention, after the test tube is clamped by the clamping mechanism, the motor is controlled to operate, the motor drives the rotating shaft to rotate, and the rotating shaft drives the mounting body to rotate, so as to shake the test tube on the mounting body, thereby achieving mixing of the blood in the test tube.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] See also Figure 1-Figure 4The embodiment of the present invention is as follows: a blood mixing device comprises: a mounting body 1, a clamping mechanism 2 and a mixing mechanism 3; the mounting body 1 is provided with a pipe blind hole 11 for accommodating a test tube 5; the clamping mechanism 2 comprises: a clamping member 21, a friction member 22 and an elastic member; the middle part of the clamping member 21 is hinged with the inner side wall of the pipe blind hole 11, the friction member 22 is fixedly mounted on one end of the clamping member 21 close to the opening end of the pipe blind hole 11, and is located on the side of the clamping member 21 close to the axis of the pipe blind hole 11; the elastic member applies a torsional force to the clamping member 21 to push the end of the clamping member 21 close to the opening end of the pipe blind hole 11 to rotate in a direction away from the axis of the pipe blind hole 11, and push the end of the clamping member 21 close to the closed end of the pipe blind hole 11 to rotate in a direction close to the axis of the pipe blind hole 11; thereby, the clamping member 21 is arranged in an inclined shape, and the end of the clamping member 21 away from the friction member 22 is located on the stroke of the test tube 5; the mixing mechanism 3 can shake the mounting body 1.

[0037] During the specific implementation, the test tube 5 after blood sampling is inserted into the blind hole 11 of the pipeline, so that the bottom end of the test tube 5 abuts on the inclined friction member 22. During the downward movement of the test tube 5, the torsional force of the elastic member on the clamping member 21 is overcome, and the end of the clamping member 21 close to the closed end of the blind hole 11 of the pipeline is pushed to rotate outward, and the end of the clamping member 21 close to the open end of the blind hole 11 of the pipeline is rotated inward, so that the clamping frame can be driven to abut, and the test tube 5 is clamped in cooperation with the inner wall of the blind hole 11 of the pipeline; for this reason, only one step of inserting the test tube 5 into the blind hole 11 of the pipeline is required to achieve the clamping of the test tube 5; the process of clamping the test tube 5 is greatly simplified, and finally the mixing mechanism 3 is started to shake the mounting body 1 to achieve the mixing of the blood in the test tube 5.

[0038] See also Figure 1-Figure 4 In other embodiments, a plurality of clamping mechanisms 2 are arranged in a circular array with the axis of the pipe blind hole 11 as the center; through the plurality of clamping mechanisms 2, the pipe blind hole 11 can be clamped in multiple directions.

[0039] See also Figure 1-Figure 4In other embodiments, a fixing mechanism 4 is also included, and the fixing mechanism 4 includes: a slide 41, a pull rope 42 and a one-way channel 43; the slide 41 is arranged in the pipeline blind hole 11 and slidably cooperates with the pipeline blind hole 11; further, a rubber ring 46 is sleeved on the outer side of the slide 41; through the setting of the rubber ring 46, the gap between the slide 41 and the inner wall of the pipeline blind hole 11 can be reduced; the end of the slide 41 close to the opening end of the pipeline blind hole 11 is provided with a groove 44 that cooperates with the bottom end of the test tube 5; further, a rubber gasket 47 is installed in the groove 44; through the setting of the rubber gasket 47, it can effectively prevent There is air leakage between the bottom of the test tube 5 and the groove 44; the slide 41 is also provided with a through hole 45 connecting the two sides of the slide 41, and the end of the through hole 45 close to the open end of the blind hole 11 of the pipeline is located in the groove 44; one end of the pull rope 42 is fixedly mounted on the slide 41, and the other end of the pull rope 42 is fixedly mounted on the clamp 21 close to the closed end of the blind hole 11 of the pipeline; a one-way channel 43 is provided on the mounting body 1, one end of the one-way channel 43 is connected to the outside world, and the other end of the one-way channel 43 is connected to the closed end of the blind hole 11 of the pipeline, and the one-way channel 43 is connected to the outside world in one direction; specifically, the one-way channel 43 can be a one-way valve.

[0040] During specific implementation, the test tube 5 is inserted into the pipe blind hole 11 through the open end of the pipe blind hole 11, so that the bottom end of the test tube 5 abuts against the clamping member 21, thereby pushing the clamping member 21 to rotate, and the test tube 5 is initially clamped by the friction member 22, and the clamping member 21 still maintains an inclined state.

[0041] The test tube 5 is continuously inserted so that the bottom end of the test tube 5 contacts the slide 41, so that the test tube 5 moves into the groove 44, and the through hole 45 in the groove 44 is pressed against and closed; the test tube 5 continues to push the slide 41 to move, and the slide 41 pulls the clamping member 21 to rotate through the pull rope 42, so as to clamp and fix the test tube 5 for the second time, thereby improving the fixing effect of the test tube 5; at the same time, the slide 41 pushes the gas in the blind hole 11 of the pipeline to be discharged through the one-way channel 43; because the elastic member applies a torsional force to the clamping member 21, the elastic member applies a force to the friction member 22 away from the test tube 5 through the clamping member 21; but because the one-way channel 43 can only exhaust but not intake air, for this reason, under the action of atmospheric pressure, the torsional force of the elastic member cannot pull the slide 41 to move toward the open end of the blind hole 11 of the pipeline, so as to fix the angle of the clamping member 21, thereby ensuring that the friction member 22 can always clamp the test tube 5.

[0042] After the blood in the test tube 5 is shaken, the test tube 5 is pulled outward so that the bottom end of the test tube 5 is separated from the groove 44 on the slide 41. For this purpose, the through hole 45 on the slide 41 reconnects the two ends of the test tube 5. For this purpose, the torsion of the elastic member can pull the slide 41 toward the open end of the blind hole 11 of the pipeline, reducing the pressure between the test tube 5 and the friction member 22, so that the test tube 5 can be easily taken out. For this reason, through the setting of the fixing mechanism 4, the test tube 5 can be clamped twice, and the slide 41 can be pushed by the test tube 5. Under the action of negative pressure, the friction force between the friction member 22 and the test tube 5 can be fixed, which greatly ensures the stability of the clamping mechanism 2 on the test tube 5, so as to reduce the probability of the test tube 5 slipping out during shaking.

[0043] See also Figure 1-Figure 4 In other embodiments, a roller 23 is installed at the end of the clamping member 21 close to the pulling end; through the setting of the roller 23, the sliding friction between the clamping member 21 and the test tube 5 can be converted into the rolling friction of the roller 23, so that the test tube 5 can more conveniently push the clamping member 21 to rotate.

[0044] See also Figure 1-Figure 4 In other embodiments, the friction member 22 is made of rubber; by setting the friction member 22 to rubber, the friction member 22 can adaptively undergo elastic deformation when in contact with the test tube 5, thereby effectively breaking the test tube 5; further, the friction member 22 can also be other materials that can undergo elastic deformation and have moving friction.

[0045] See also Figure 1-Figure 4 In other embodiments, the elastic member is a torsion spring; the torsion spring is arranged at the hinge of the clamping member 21, and a torsion force can be more conveniently applied to the clamping member 21 through the torsion spring, so that the clamping member 21 can rotate. Further, the elastic member can also be a spring, which is arranged vertically with the clamping member 21 and installed at one end of the clamping member 21, so as to apply a torsion force to the clamping member 21; further, the elastic member can also be other elastic materials, so as to push or pull the clamping member 21 to rotate.

[0046] See also Figure 1-Figure 4 In another embodiment, the mixing mechanism 3 includes: a frame 31, a rotating shaft 32 and a motor 33; the mounting body 1 is rotatably mounted on the frame 31 via the rotating shaft 32, and the rotating shaft 32 is arranged perpendicular to the axis of the pipeline blind hole 11; the motor 33 can rotate by driving the mounting body 1. In specific implementation, after the test tube 5 is clamped by the clamping mechanism 2, the motor 33 is controlled to operate, the motor 33 drives the rotating shaft 32 to rotate, and the rotating shaft 32 drives the mounting body 1 to rotate, so as to shake the test tube 5 on the mounting body 1, and then achieve mixing of the blood in the test tube 5.
