Description

Technical Field

[0001] The present invention belongs to the technical field of blood collection and mixing, and specifically refers to a blood collection and mixing device for a laboratory department. Background Art

[0002] The laboratory department is a bridge between clinical medicine and basic medicine, including sub-disciplines such as clinical chemistry, clinical microbiology, clinical immunology, hematology, body fluidology, and transfusion medicine. After collecting blood in a blood bag, it is often necessary to mix the collected blood to facilitate blood testing.

[0003] Existing blood collection and mixing solutions for laboratory departments mostly involve manually shaking the blood bag or using existing mechanical reciprocating mixing equipment for mixing operations. It is difficult to know the viscosity of the blood in the blood bag and whether the blood in the blood bag has coagulated. Therefore, a blood collection and mixing device for a laboratory department needs to be proposed. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a blood collection and mixing solution with an adaptive stop component and an automatic start component, effectively solving the problem that the existing blood collection and mixing solutions on the market cannot automatically adjust the mixing intensity according to the viscosity of the blood.

[0005] The technical solution adopted by the present invention is as follows: A blood collection and mixing device for a laboratory department includes legs, a support box, a mixing barrel, an adaptive stop component, an automatic start component, a bubbling component, and a rotating component. The support box is fixedly arranged at the top of the legs, the mixing barrel is fixedly arranged on the support box, the adaptive stop component is arranged in the support box, the automatic start component is arranged in the support box, the bubbling component is fixedly arranged on the support box, and the rotating component is arranged in the mixing barrel. The automatic start component monitors the viscosity of the blood in the mixing barrel, controls the bubbling component to add gas into the mixing barrel, the adaptive stop component automatically determines the amount of gas added into the mixing barrel according to the viscosity of the blood in the mixing barrel, and controls the bubbling component to stop adding gas, and the rotating component mixes the blood in the mixing barrel.

[0006] Furthermore, the adaptive stop component includes a stop maintaining power component, a main power component, a recycling stop component, an adaptive timing component, and a one-way rotation component. The stop maintaining power component is disposed on the bottom wall of the support box. The end of the main power component is fixedly disposed on the stop maintaining power component. The recycling stop component is disposed on the bottom wall of the support box. The adaptive timing component is disposed on the support box. One end of the one-way rotation component is disposed on the main power component, and the other end of the one-way rotation component is disposed on the recycling stop component. Blood with different viscosities causes the operating distance of the stop maintaining power component to be different, drives the operating distance of the main power component to be different, and the main power component drives the moving distance of the recycling stop component to be different, so that the working duration of the bubbling component is different. The adaptive timing component is targeted at the different pressures of the blood on the recycling stop component, so that the gas injection time for relatively viscous blood is longer. The one-way rotation component can effectively prevent the recycling speed of the stop maintaining power component from affecting the working duration of the recycling stop component.

[0007] Furthermore, the stop maintaining power component includes a first fixing plate, a first liquid storage bag, a first fixing frame, a first transfer cylinder, a first piston plate, a transfer rod, and a push plate. The first fixing plate is fixedly disposed on the rotation component. The first fixing frame is fixedly disposed on the bottom wall of the support box. The first liquid storage bag is disposed in the first fixing frame. There is a fluid in the first liquid storage bag. The first transfer cylinder is fixedly disposed on the bottom wall of the support box. The first transfer cylinder is relatively long. One end of the first transfer cylinder is fixedly disposed on the first liquid storage bag. The first piston plate slides in the first transfer cylinder. One end of the transfer rod is fixedly disposed on the first piston plate. The push plate is fixedly disposed on the other end of the transfer rod. The viscosities of the blood in the mixing barrel are different, the force exerted by the rotation component on the first fixing plate is different, the force exerted by the first fixing plate on the first liquid storage bag is different, and the distance that the fluid in the first liquid storage bag pushes the first piston plate to move is different.

[0008] Furthermore, the main power component includes a support plate, a first toothed plate, a first transmission plate, a first return spring, a positioning plate, a bracket, a first rotating shaft, and a first gear. The support plate is fixedly disposed on the bottom wall of the support box. The first toothed plate slides on the support plate. One end of the first toothed plate is fixedly disposed on the push plate. The first transmission plate is fixedly disposed on the other end of the first toothed plate. One end of the first return spring is fixedly disposed on the first transmission plate. The positioning plate is fixedly disposed on the bottom wall of the support box. The other end of the first return spring is fixedly disposed on the positioning plate. There are four groups of brackets. The bottoms of the four groups of brackets are all fixedly disposed on the bottom wall of the support box. The first rotating shaft rotates on two of the groups of brackets. The first gear is fixedly disposed on the first rotating shaft. The first gear is meshed and connected with the first toothed plate. While the push plate drives the first gear to rotate through the first toothed plate, the first return spring is compressed, which is convenient for the first toothed plate to return to its original position.

[0009] Further, the recycling stop assembly includes a stop switch, an F clamping plate, a second toothed plate, a second transmission plate, a second return spring, a second rotating shaft, and a second gear. The stop switch is fixedly arranged on the bottom wall of the support box and is electrically connected to the bubbling assembly. The F clamping plate is fixedly arranged on the bottom wall of the support box, and there are two groups of F clamping plates. The second toothed plate is slidably arranged on the F clamping plate. The second transmission plate is fixedly arranged at the end of the second toothed plate. One end of the second return spring is fixedly arranged on the second transmission plate, and the other end of the second return spring is fixedly arranged on the positioning plate. The second rotating shaft is rotatably arranged on the other two groups of brackets. The side of the second rotating shaft close to the first gear is polygonal. The second gear is fixedly arranged on the second rotating shaft, and the second gear is meshed and connected with the second toothed plate. The first rotating shaft drives the second rotating shaft to rotate through the one-way rotation assembly. The second rotating shaft drives the second toothed plate to move through the second gear. The second toothed plate presses the second return spring, so that when the second toothed plate returns to its original position, it presses the stop switch.

[0010] Further, the adaptive timing control assembly includes a protective shell, a third gear, a rack, a pressing plate, a positioning rod, a sliding plate, a pressure spring, and a pressing block. The protective shell is fixedly arranged on the outer wall of the support box. The third gear is fixedly arranged on the second rotating shaft. The rack is slidably arranged on the inner wall of the protective shell. The pressing plate is fixedly arranged at the bottom end of the rack. The bottom end of the positioning rod is fixedly arranged on the bottom wall of the protective shell, and there are two groups of positioning rods. The sliding plate is slidably arranged on the two groups of positioning rods. The bottom end of the pressure spring is fixedly arranged on the sliding plate. The pressing block is fixedly arranged at the top end of the pressure spring. The pressing block is slidably arranged on the bottom surface of the second toothed plate. The second rotating shaft drives the rack to move, and through the pressing plate and the sliding plate, the pressure spring is compressed. Since the moving distance of the rack is different, the pressing force on the pressure spring is different, so that the dynamic friction force generated by the pressing block on the bottom surface of the second toothed plate is different.

[0011] Further, the one-way rotation assembly includes a one-way slope female wheel, a positioning circular plate, a male wheel, and a displacement spring. The one-way slope female wheel is fixedly arranged on the first rotating shaft. The positioning circular plate is fixedly arranged on the second rotating shaft. The male wheel is slidably arranged on the second rotating shaft. One end of the displacement spring is fixedly arranged on the positioning circular plate, and the other end of the displacement spring is fixedly arranged on the male wheel. When the first rotating shaft rotates in one direction, the displacement spring clamps the male wheel into the one-way slope female wheel, and drives the male wheel to rotate through the one-way slope female wheel, so as to drive the second rotating shaft to rotate. When the first rotating shaft rotates in the reverse direction, the one-way slope female wheel cannot drive the male wheel to rotate.

[0012] Further, the automatic activation component includes a second fixing plate, a second liquid storage bag, a second fixing frame, a second transfer cylinder, a pulling-back spring, a second piston plate, a start switch, a secondary plate, and a non-moving spring. The second fixing plate is fixedly arranged on the rotating component, the second fixing frame is fixedly arranged on the bottom wall of the support box, the second liquid storage bag is arranged inside the second fixing frame, a fluid is provided inside the second liquid storage bag, one end of the second transfer cylinder is fixedly arranged on the second liquid storage bag, the second transfer cylinder is fixedly arranged on the bottom wall of the support box, the second transfer cylinder is relatively short, one end of the pulling-back spring is fixedly arranged on the inner wall of the second transfer cylinder, the second piston plate is slidably arranged inside the second transfer cylinder, the second piston plate is fixedly arranged on the other end of the pulling-back spring, the start switch is fixedly arranged inside the second transfer cylinder, the start switch is electrically connected to the bubbling component, the secondary plate is slidably arranged inside the second transfer cylinder, one end of the non-moving spring is fixedly arranged on the secondary plate, and the other end of the non-moving spring is fixedly arranged on the second piston plate. The fluid in the second liquid storage bag is squeezed into the second transfer cylinder through the second fixing plate, thereby pushing the second piston plate to slide inside the second transfer cylinder. The piston plate pushes the secondary plate to move through the non-moving spring, and the secondary plate squeezes the start switch, causing the bubbling component to operate.

[0013] Further, the bubbling component includes an air pump, an intake pipe, an outlet pipe, a branch pipe, and a nozzle. The air pump is fixedly arranged on the top of the support box, one end of the intake pipe is connected to the air inlet of the air pump, the other end of the intake pipe is connected to an external air source, the branch pipe is fixedly arranged on the mixing barrel, the nozzle is fixedly arranged on the branch pipe, several groups of nozzles are provided, one end of the outlet pipe is connected to the air outlet of the air pump, the other end of the outlet pipe is connected to the branch pipe, the air pump is electrically connected to an external power source, the start switch is electrically connected to the air pump, the stop switch is electrically connected to the air pump, and air is input into the mixing barrel through the intake pipe, the air pump, the outlet pipe, the branch pipe, and the nozzle.

[0014] Further, the rotating component includes a motor, a support plate, a rotating shaft, and rotating blades. The body of the motor is arranged on the bottom wall of the support box, the rotation amplitude of the motor is relatively small, both ends of the support plate are fixedly arranged on the inner wall of the mixing barrel, the bottom end of the rotating shaft is fixedly arranged on the output end of the motor, the top end of the rotating shaft is rotatably arranged on the support plate, the rotating blades are fixedly arranged on the rotating shaft, the motor is electrically connected to an external power source, the first fixing plate is fixedly arranged on the output end of the motor, the second fixing plate is fixedly arranged on the output end of the motor, the motor drives the rotating shaft to rotate, and the blood in the mixing barrel is mixed through the rotating blades.

[0015] The present invention provides a blood collection and mixing solution with an adaptive stop component and an automatic activation component, effectively solving the problem that the blood collection and mixing solution cannot automatically adjust the mixing intensity according to the viscosity of the blood. The beneficial effects obtained by the present invention with the above structure are as follows: (1) The motor is rotatably arranged on the bottom wall of the support box, and by providing a liquid storage bag filled with a fluid inside, the change in the torque magnitude of the rotating shaft is transformed into the change in the movement distance of the fluid, thereby achieving the effect of monitoring the viscosity of the blood in the mixing barrel and being able to automatically determine the air injection volume according to the viscosity of the blood; (2) Electrically connect the start switch to the gas filling pump, and set a non-movable spring and a pulling-back spring on the second piston plate. When the viscosity of the blood in the mixing barrel is relatively low, the secondary plate can also squeeze the start switch to start the gas filling pump. When the viscosity of the blood in the mixing barrel is relatively high, the non-movable spring is compressed to a greater extent, and the secondary plate still remains in the state of squeezing the start switch, achieving the effect that blood with different viscosities can all react to the start switch; (3) Initially, due to the different viscosities of the blood, the squeezing force of the fixed plate one on the liquid storage bag one is different, so that the moving distance of the first gear plate is different, the number of turns of the rotation of the second shaft driven by the first shaft is different, and the moving distance of the second gear plate is different. Electrically connect the stop switch to the gas filling pump. When the second gear plate retracts and squeezes the stop switch, the gas filling pump stops working, achieving the effect of automatically determining the required gas volume according to the viscosity of the blood and controlling the required gas volume, which is convenient for adjusting the viscosity of the blood; (4) The number of turns of the rotation of the second shaft is different, the upward moving distance of the rack is different, the degree of compression of the pressure spring by the sliding plate is different, and the sliding friction force generated by the pressing block on the second gear plate is also different. That is, when the viscosity of the blood in the mixing barrel is relatively high, the moving distance of the second gear plate is farther, and the sliding friction force generated by the pressing block on the second gear plate is greater. When the viscosity of the blood in the mixing barrel is relatively low, the moving distance of the second gear plate is closer, and the sliding friction force generated by the pressing block on the second gear plate is smaller, achieving the effect of adjusting the size of the sliding friction force according to the viscosity of the blood in the mixing barrel. When the rack moves downward as the second gear plate retracts, the pressure on the pressure spring gradually decreases, and the sliding friction force generated by the pressing block on the second gear plate gradually decreases, thus also balancing the unevenness of the thrust of the second reset spring on the second gear plate, making the second gear plate basically in a uniform motion state, ensuring the balance of gas filling and the gas filling volume; (5) By setting the one-way slope female wheel and the male wheel, when the first gear plate moves towards the positioning plate, the first shaft can drive the second shaft to rotate, so that the second gear plate and the rack move synchronously. As gas is continuously filled into the mixing barrel, the first gear plate retracts. At this time, due to the existence of the one-way slope female wheel, the first shaft cannot drive the second shaft to rotate, thus avoiding the problem that the retraction of the first gear plate affects the normal retraction of the second gear plate, that is, avoiding the problem of affecting the gas filling volume.

The body of the motor 59 is arranged on the bottom wall of the support box 2, the rotation amplitude of the motor 59 is relatively small, both ends of the support plate 60 are fixedly arranged on the inner wall of the mixing barrel 3, the bottom end of the rotating shaft 61 is fixedly arranged on the output end of the motor 59, the top end of the rotating shaft 61 is rotatably arranged on the support plate 60, the rotating blade 62 is fixedly arranged on the rotating shaft 61, the motor 59 is electrically connected to an external power source, the first fixing plate 13 is fixedly arranged on the output end of the motor 59, and the second fixing plate 47 is fixedly arranged on the output end of the motor 59.

The first piston plate 17 pushes the transfer rod 18 to slide, the transfer rod 18 pushes the push plate 19 to slide, the push plate 19 pushes the first toothed plate 21 to slide. While the first toothed plate 21 pushes the first transmission plate 22 to slide, it drives the first gear 27 to rotate.

Under the action of the first return spring 23, the first transmission plate 22 moves in the reverse direction. The first transmission plate 22 pushes the first toothed plate 21 to move in the reverse direction. While the first toothed plate 21 drives the first gear 27 to rotate in the reverse direction, it pushes the push plate 19 to move in the reverse direction. The push plate 19 pushes the fluid in the first transfer cylinder 16 to flow back to the first liquid storage bag 14 through the transfer rod 18 and the first piston plate 17. The first gear 27 drives the first rotating shaft 26 to rotate in the reverse direction.The first rotating shaft 26 drives the one-way slope female wheel 43 to rotate in the reverse direction. The one-way slope female wheel 43 squeezes the male wheel 45, and the male wheel 45 squeezes the displacement spring 46. The male wheel 45 moves in the direction of the third gear 36. The one-way slope female wheel 43 no longer drives the male wheel 45 to rotate, so that the reverse rotation of the first rotating shaft 26 no longer affects the rotation state of the second rotating shaft 33. The second return spring 32 pushes the second transmission plate 31 to move in the reverse direction. The second transmission plate 31 pushes the second toothed plate 30 to move in the reverse direction. The second toothed plate 30 drives the second gear 34 to rotate. The second gear 34 drives the second rotating shaft 33 to rotate in the reverse direction. The second rotating shaft 33 drives the third gear 36 to rotate in the reverse direction. The third gear 36 drives the rack 37 to move downward. The rack 37 drives the sliding plate 40 to move downward through the pressing plate 38. The pressure of the pressure spring 41 on the pressing block 42 decreases. The pressure of the pressing block 42 on the bottom of the second toothed plate 30 decreases. When the second toothed plate 30 squeezes the stop switch 28, the air filling pump 54 stops working.
