Description

Technical Field

[0001] This invention relates to the field of hospital laboratory technology, and in particular to a test tube shaking device for use in hospital laboratory departments. Background Technology

[0002] When conducting research on patient data in hospitals, it is generally necessary to shake and agitate the collected samples and mixtures in the test tubes to accelerate their fusion and facilitate subsequent observation. Typically, the higher the vibration frequency and angle, the better the shaking effect and the faster the fusion reaction between the samples and the mixture. In hospital laboratories, test tube shaking is usually performed manually by researchers, but this is inefficient. With technological advancements, test tube shaking equipment has emerged to continuously shake and agitate the test tubes, accelerating the shaking process and saving labor.

[0003] Traditional test tube shaking devices typically use horizontal force to reciprocate and vibrate. This unidirectional shaking results in the precipitate at the bottom of the test tube not being fully mixed with the liquid, leading to poor shaking effect. Furthermore, the poor stability between the test tube and the clamping structure during shaking can cause the test tube to slip out and break. Summary of the Invention

[0004] The purpose of this invention is to address the problems in the background art where traditional test tube shaking devices have a single shaking direction during the shaking process, resulting in the bottom sediment not being fully mixed with the mixture. At the same time, the device has poor clamping stability and cannot form a stable clamping effect on the test tube. During violent shaking, the test tube is prone to slipping out and breaking. The invention proposes a test tube shaking device for hospital laboratory departments.

An electromagnet is fixedly connected to the farthest end of the output shaft of the second electric push rod.

[0007] Preferably, the micro-oscillation mechanism includes a stabilizing bar, which is fixedly installed in the middle of the inner wall of the test tube rack. Small vibrators are installed at the bottom of both ends of the stabilizing bar. The stabilizing bar has multiple storage holes that are adapted to the slots, and sponge rings for protecting the outer wall of the test tubes are installed in the storage holes.

[0008] Preferably, the bottom rotation radius of the bottom limiting mechanism is smaller than the distance between the test tube rack and the inner wall of the shaking box, and the farthest point of the output shaft retraction of the second electric push rod is located inside the shaking box.

[0009] Preferably, a protective cover is snapped onto the top of the oscillation box, and the protective cover is made of lightweight transparent plastic.

[0010] Preferably, the bottom limiting mechanism includes a first electric push rod and a sealing box. Both the first electric push rod and the sealing box are fixedly connected to the bottom of the test tube rack. The output shaft of the first electric push rod is fixedly connected to a piston rod. One end of the piston rod passes through the sealing box and is fixedly connected to a piston block. The piston block is piston-connected to the internal cavity of the sealing box. An air extraction chamber is provided in the bottom of the test tube rack. The cavity of the sealing box is connected to the air extraction chamber. Multiple rubber sleeves that are adapted to the slots and test tubes are connected through the bottom of the inner wall of the test tube rack. The rubber sleeves are connected to the air extraction chamber.

[0011] Preferably, the top limiting mechanism includes multiple rubber rings, which are respectively bonded and fixed to the inner wall of the slot. The top of the test tube rack has multiple annular cavities and air guiding cavities that are adapted to the rubber rings. An air guiding box is fixedly connected to the side wall of the test tube rack near the top. The multiple air guiding cavities are simultaneously connected to the air guiding box.

[0012] Preferably, sealing rings for enhancing sealing are embedded in both the outer wall of the piston block and the through-hole of the sealing box.

[0013] Preferably, the top of the test tube rack has two slots, and clips are inserted into the two slots. The clips and slots are provided with damping stops.

[0014] Preferably, a protective pad is fixedly connected to the top of the inner wall of the clip, and the protective pad is made of rubber with a high shock absorption coefficient.

[0015] Beneficial effects Compared with the prior art, the present invention has the following beneficial technical effects: This application uses a motor to drive a sliding plate to rotate, which in turn carries the test tube rack and test tubes to rotate. By controlling the motor speed, the test tubes can be shaken at different angles of 360 degrees. Compared with the traditional single reciprocating shaking method, this shaking method can promote a deeper and more thorough reaction and fusion between the collected material and the mixture from more angles. At the same time, with the cooperation of the micro-oscillation mechanism, it can meet the needs of experimenters for different amplitude oscillation experiments between the collected material and the mixture, thus improving the applicability of the device. Furthermore, with the coordinated action of the top and bottom limiting mechanisms, the test tube can be clamped and limited more comprehensively from top to bottom, protecting it from shaking at multiple angles and preventing it from slipping out and breaking during traditional multi-angle shaking.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] like Figure 1-6 As shown, the present invention proposes a test tube shaking device for a hospital laboratory, comprising a shaking box 1, a motor 3, the motor 3 being fixedly mounted on the side wall of the shaking box 1 near the top, and the output shaft passing through the shaking box 1; two slide plates 2, each rotatably connected to both sides of the inner wall of the shaking box 1, one side of which is fixedly connected to the output shaft of the motor 3; a test tube rack 4, both ends of which are respectively limited and slidably connected to the two slide plates 2, and the top of the test tube rack 4 having multiple slots for inserting test tubes; a horizontal shaking mechanism 7 for adjusting the shaking direction of the test tubes is installed between the test tube rack 4 and the shaking box 1; a micro-shaking mechanism 8 for slightly shaking the test tubes is installed on the inner wall of the test tube rack 4; a bottom limiting mechanism 5 for improving the stability of the test tubes is fixedly installed at the bottom of the test tube rack 4; a top limiting mechanism 6 for further improving the test tube clamping effect is installed on the side wall of the test tube rack 4 near the top, and the top limiting mechanism 6 is connected to the bottom limiting mechanism 5.

[0022] Furthermore, the horizontal shaking mechanism 7 includes a second electric push rod 701 and a magnetic block 702. The second electric push rod 701 is fixedly installed on one side of the outer wall of the shaking box 1, and its output shaft passes through the shaking box 1. The magnetic block 702 is fixedly connected to the outer wall of the test tube rack 4 near the top, and corresponds to the position of the output shaft of the horizontal shaking mechanism 7. An electromagnet 703 is fixedly connected to the farthest end of the output shaft of the second electric push rod 701. With the above settings, when the electromagnet 703 is activated, the electromagnet 703 generates a magnetism opposite to that of the magnetic block 702, so opposite poles attract each other. When the output shaft of the second electric push rod 701 moves to the farthest end, the electromagnet 703 will come into contact with and attract the magnetic block 702. Under the strong magnetic attraction, the magnetic block 702 can drive the test tube rack 4 to move back and forth in the slide plate 2 under the drag of the second electric push rod 701, achieving a horizontal reciprocating shaking effect.

[0023] Furthermore, the micro-oscillation mechanism 8 includes a stabilizing bar 801, which is fixedly installed in the middle of the inner wall of the test tube rack 4. Small vibrators 802 are installed at both ends of the stabilizing bar 801. The stabilizing bar 801 has multiple storage holes 803 that are adapted to the slots, and sponge rings for protecting the outer wall of the test tubes are installed in the storage holes 803. With this setting, after the small vibrators 802 are started, a slight vibration force will be generated. The vibration force is transmitted from the stabilizing bar 801 to the outer wall of the test tube in the storage hole 803. The sponge rings in the storage hole 803 will protect the outer wall of the test tube, ensuring that the sample and mixture in the test tube will produce a slight oscillation under the propagation of the vibration force. This meets the needs of the experimenters for different amplitude oscillation experiments between the sample and the mixture, and improves the applicability of the device.

[0024] The bottom rotation radius of the bottom limiting mechanism 5 is smaller than the distance between the test tube rack 4 and the inner wall of the shaking box 1. The farthest point of the output shaft of the second electric push rod 701 is located inside the shaking box 1. With this setting, when the test tube rack 4 rotates, the output shaft of the second electric push rod 701 retracts into the shaking box 1, thereby ensuring the normal rotation of the test tube rack 4 and the bottom limiting mechanism 5, preventing structural collisions, and improving the safety of the device.

[0025] In addition, a protective cover 12 is snapped onto the top of the shaking box 1. The protective cover 12 is made of lightweight transparent plastic. This design facilitates personnel handling, protects all structures inside the shaking box 1, prevents structures or test tubes from accidentally flying out and causing personnel safety issues, and allows personnel to easily observe the shaking of the test tubes inside.

[0026] Furthermore, the bottom limiting mechanism 5 includes a first electric push rod 501 and a sealing box 504. Both the first electric push rod 501 and the sealing box 504 are fixedly connected to the bottom of the test tube rack 4. The output shaft of the first electric push rod 501 is fixedly connected to a piston rod 502. One end of the piston rod 502 passes through the sealing box 504 and is fixedly connected to a piston block 503. The piston block 503 is piston-connected to the internal cavity of the sealing box 504. A suction chamber 505 is opened in the bottom of the test tube rack 4. The cavity of the sealing box 504 is connected to the suction chamber 505. Multiple rubber inserts adapted to slots and test tubes are connected through the bottom of the inner wall of the test tube rack 4. The rubber sleeve 506 is connected to the suction chamber 505. With the above configuration, after the first electric push rod 501 is started, the output shaft of the first electric push rod 501 will drive the piston rod 502 to move back and forth, thereby controlling the movement direction of the piston block 503 in the sealing box 504. During this process, the suction chamber 505 is evacuated and blown, so that the rubber sleeve 506 can perform negative pressure adsorption or positive pressure lifting on the bottom of the inserted test tube. This is used to assist the rubber sleeve 506 in adsorbing and blowing the bottom of the test tube, achieving the purpose of clamping and limiting the bottom of the test tube and assisting in disassembly and assembly.

[0027] Furthermore, the top limiting mechanism 6 includes multiple rubber rings 601, which are respectively bonded and fixed to the inner wall of the slot. The top of the test tube rack 4 has multiple annular cavities 602 and air guiding cavities 603 that are adapted to the rubber rings 601. An air guiding box 604 is fixedly connected to the side wall of the test tube rack 4 near the top. The multiple air guiding cavities 603 are simultaneously connected to the air guiding box 604. An air guiding tube 605 is connected through the air guiding box 604 and the sealing box 504. With the above settings, when the piston block 503 evacuates the sealing box 504, it pushes the air at the other end of the piston block 503 and the sealing box 504 to enter the air guide box 604 through the air guide pipe 605. The air then evenly fills the multiple air guide chambers 603 and the annular cavity 602 from the air guide box 604, causing the elastic rubber ring 601 to expand in the middle, thereby squeezing the outer wall of the test tube and forming a tighter and more stable clamping effect, further enhancing the stability of the test tube in the slot.

[0028] The piston block 503 has a sealing ring embedded in its outer wall and the sealing box 504 through which it passes. This design ensures that the air can only be stably squeezed and released at both ends of the sealing box 504 when the piston block 503 moves. This ensures that the bottom limiting mechanism 5 and the top limiting mechanism 6 can be stably linked, thus guaranteeing a reliable clamping effect on the bottom of the test tube and the body of the test tube.

[0029] The test tube rack 4 has two slots 9 on its top, and clips 10 are inserted into the two slots 9. The clips 10 and the slots 9 are equipped with damping stops. Through this setting, the height of the clips 10 can be freely changed, so as to maintain a stable abutment effect on the top of different test tubes within a certain range and avoid the problem of the test tubes slipping out and breaking during shaking and vibration.

[0030] In addition, a protective pad 11 is fixedly connected to the top of the inner wall of the clip 10. The protective pad 11 is made of rubber with a high shock absorption coefficient. With this setting, when the clip 10 abuts and limits the top of the test tube, it can achieve a better protection effect on the top of the test tube and the bottle body, avoid the problem of expansion and breakage between the top of the test tube and the clip 10, and improve the protection effect of the device on the test tube.

[0031] The working principle of this embodiment is as follows: After multiple test tubes are inserted into the test tube rack 4, the first electric push rod 501 in the bottom limiting mechanism 5 is activated. After the first electric push rod 501 is activated, the output shaft of the first electric push rod 501 will drive the piston rod 502 to move back and forth, thereby controlling the movement direction of the piston block 503 in the sealing box 504. During this process, air is drawn and blown into the suction chamber 505, thereby enabling the rubber sleeve 506 to perform negative pressure adsorption or positive pressure lifting on the bottom of the inserted test tubes, which is used to assist the rubber sleeve 506 in adsorbing the bottom of the test tubes. The effect of blowing up the test tube achieves the purpose of clamping and limiting the bottom of the test tube and assisting in disassembly and assembly. When the piston block 503 evacuates the sealing box 504, it pushes the air at the other end of the piston block 503 and the sealing box 504 through the air guide pipe 605 into the air guide box 604. The air is then evenly filled from the air guide box 604 into multiple air guide chambers 603 and annular chamber 602, causing the elastic rubber ring 601 to expand in the middle, thereby squeezing the outer wall of the test tube. This achieves a tighter and more stable clamping effect of the top limiting mechanism 6 on the test tube, further enhancing the stability of the test tube in the slot. Subsequently, electromagnet 703 is activated, and electromagnet 703 generates a magnetism opposite to that of magnetic block 702. Thus, opposite poles attract each other, causing electromagnet 703 to come into contact with magnetic block 702 when the output shaft of the second electric push rod 701 moves to its farthest point. Under the strong magnetic attraction, magnetic block 702 can drive test tube rack 4 to move back and forth in the slide plate 2 under the drag of the second electric push rod 701, achieving a horizontal reciprocating swaying effect. The small vibrator 802 inside the micro-oscillation mechanism 8 generates a slight vibration force. This vibration force is transmitted from the stabilizing bar 801 to the outer wall of the test tube inside the receiving hole 803. The sponge ring inside the receiving hole 803 protects the outer wall of the test tube, ensuring that the sample and mixture inside the test tube oscillate slightly under the propagation of the vibration force. This meets the needs of experimenters for different amplitude oscillation experiments between the sample and the mixture, and improves the applicability of the device. Furthermore, when the test tubes need to be rotated and shaken 360 degrees, simply turn off the electromagnet 703 to disengage it from the magnetic block 702. At this time, the control motor 3 will start, which will drive the slide plate 2 and the test tube rack 4 to rotate and shake. During the rotation and shaking process, the test tube rack 4 can be positioned using an external plug-in. When not positioned, the test tubes in the test tube rack 4 can move horizontally while rotating and shaking, thus achieving a more diverse shaking effect. This allows the collected materials and the mixture to mix and react more effectively, improving the vibration effect of the device.

[0032] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
