Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a stirring device for a gastroenterology experiment. Background Art

[0002] Experimental stirring refers to the process of mixing experimental materials and controlling reactions using a stirrer or stirring device. In the field of gastroenterology, researchers often need to handle a variety of complex biological samples and chemical reagents, which have special requirements in terms of mixing, reaction, and temperature changes.

[0003] Stirring can accelerate the mixing and reaction between experimental materials, improve experimental efficiency, and ensure that the experimental materials are evenly distributed in the mixing barrel to avoid the influence of local concentrations that are too high or too low on the experimental results. Stirring also helps to simulate the dynamic digestion environment in the body and promote the occurrence of digestion reactions, so as to more accurately study the complex mechanisms in the digestion process.

[0004] At present, the existing experimental stirring devices are mostly used to stir the experimental materials when stirring biological samples. However, as the experimental process is prolonged, the experimental materials will produce precipitation in the stirring device, and excessive precipitation will have a certain impact on the experimental results. Therefore, it is necessary to propose a gastroenterology experimental stirring device that can reduce the precipitation of experimental materials. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a gastroenterology experiment stirring device, which drives the rack to move horizontally through a driving member, and utilizes the horizontal movement of the rack to drive the piston head to move in the piston cylinder, thereby generating airflow, and utilizes the airflow to stir the biological sample in the stirring barrel again, thereby reducing the occurrence of precipitation of experimental materials.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a gastroenterology experimental stirring device, comprising a box body, a feeding port is opened on the top of the box body, a top cover is detachably connected to the feeding port, a feeding port is opened on the side wall of the box body, a controller is fixedly connected to the surface of the box body, a stirring barrel is fixedly connected to the inner wall of the box body, the top of the stirring barrel is connected to the feeding port, the bottom of the stirring barrel is connected to the feeding port, and a vibration component for vibrating the stirring barrel is provided at the bottom of the stirring barrel.

[0007] A first support rod is fixedly connected to the bottom wall of the box body, a driving member is fixedly connected to the top of the first support rod, a controller is used to control the start and stop of the driving member, one end of the driving member penetrates into the mixing barrel and is provided with a stirring assembly for experimental stirring, one end of the driving member away from the mixing barrel is fixedly connected to a rotating rod, and one end of the rotating rod away from the driving member is fixedly connected to a sliding block.

[0008] The bottom wall of the box body is fixedly connected with a second support rod, and an "L"-shaped fixing plate is symmetrically fixedly connected to the second support rod, and one end of the fixing plate away from the second support rod is fixedly connected with a piston cylinder.

[0009] A rack is provided on one side of the second support rod close to the first support rod, and a sliding groove is fixedly connected to one side of the rack close to the first support rod, and the sliding groove is slidably matched with the sliding block.

[0010] Both ends of the rack are fixedly connected with piston heads, and the piston heads are slidably matched with the adjacent piston cylinders; the top of the piston cylinder away from the piston head is provided with an air inlet, and the bottom is provided with an air outlet, and the air outlet is connected to the mixing barrel.

[0011] The rack is meshed with a gear, and a swing component for striking the vibration component is provided on one side of the gear close to the second support rod and passes through the second support rod.

[0012] The technical principles of the above scheme are as follows:

[0013] Add the experimental materials into the mixing barrel through the inlet, and then cover it with a removable top cover to ensure safety and closure during the mixing process. Start the drive unit through the controller, and one end of the motor drives the mixing component to rotate in the mixing barrel to mix and stir the experimental materials.

[0014] The other end of the driving member drives the rack to slide in the horizontal direction through the rotating rod and the slider. The movement of the rack drives the piston head fixedly connected to it to slide in the piston cylinder. When the piston head moves away from the piston cylinder, the gas in the piston cylinder is sucked in through the air inlet; when the piston head moves toward the piston cylinder, the gas is compressed and injected into the mixing barrel through the air outlet, thereby performing secondary mixing on the experimental materials. This reduces the occurrence of precipitation of experimental materials.

[0015] The movement of the rack further drives the gear meshing with it to rotate. The rotation of the gear hits the vibration component through the swing component, causing the mixing barrel to vibrate. This vibration helps to mix the experimental materials more evenly.

[0016] The above scheme has the following beneficial effects:

[0017] 1. The present invention effectively improves the stirring efficiency and uniformity of experimental materials through the combined action of the stirring component and the vibration component driven by the driving member, and is particularly suitable for biological samples that need to be fully mixed in gastroenterology experiments.

[0018] 2. The present invention generates gas flow in the stirring barrel through the design of the piston cylinder and the piston head, and uses the airflow to perform secondary stirring on the biological sample, thereby reducing the precipitation of the biological sample during a long experiment, thereby improving the accuracy of the biological sample experiment.

[0019] Furthermore, the stirring assembly includes a stirring rod, which is coaxially fixedly connected to the output shaft of the driving member, and a plurality of stirring blades are fixedly connected to the stirring rod.

[0020] Beneficial effects: The stirring rod is coaxially fixedly connected to the driving member, which ensures direct transmission of power, reduces energy loss and improves stirring efficiency.

[0021] The stirring blades fixedly connected to the stirring rod rotate under the drive of the motor to stir the experimental materials in all directions to ensure that the materials are mixed evenly.

[0022] Furthermore, the vibration assembly includes a vibration plate, a plurality of springs are fixedly connected to the bottom of the vibration plate, the ends of the springs away from the vibration plate are fixedly connected to the bottom wall of the box body, and the top of the vibration plate contacts the bottom of the mixing barrel.

[0023] Beneficial effect: When the swing component hits the vibration plate, the vibration plate will drop under the action of the swing component, and under the elastic force of the spring, the vibration plate will rise and collide with the mixing barrel, thereby causing the mixing barrel to vibrate. This vibration can accelerate the mixing process of the experimental materials in the mixing barrel, especially for viscous or difficult-to-mix materials, the vibration can destroy their internal cohesion, making them easier to disperse and mix.

[0024] Furthermore, the swing assembly includes a swing plate, the swing plate is fixedly connected to the gear, and the vibration plate is in contact with the swing plate.

[0025] Beneficial effect: The swing plate can directly hit the vibration plate when in motion, thereby achieving vibration of the vibration plate without the need for an additional transmission mechanism. This direct hitting method can reduce energy loss and improve vibration efficiency.

[0026] Furthermore, a threaded groove for guiding airflow is provided on the inner wall of the mixing barrel.

[0027] Beneficial effects: The design of the spiral groove can guide the airflow to flow along a specific path, reducing the turbulence and ineffective flow of the airflow. This orderly airflow helps to improve the mixing efficiency, allowing the airflow to contact and mix with the materials in the mixing barrel more effectively.

[0028] Furthermore, the bottom of the mixing barrel is made of elastic material.

[0029] Beneficial effect: The elastic material has good vibration transmission performance. When the vibration plate hits the elastic material at the bottom of the mixing barrel, the vibration can be quickly and effectively transmitted to the material in the mixing barrel.

[0030] The bottom of the mixing barrel made of elastic material will deform and recover when hit by the vibration plate. This deformation and recovery process can generate additional stirring force. This stirring force can accelerate the relative movement between materials, break the agglomeration and adhesion between materials, and thus improve the mixing efficiency.

[0031] Furthermore, the air inlet and the air outlet are both fixedly connected to a solenoid valve, and the controller is used to control the opening and closing of the solenoid valve.

[0032] Beneficial effect: By precisely controlling the opening and closing of the solenoid valve through the controller, precise control of the airflow in and out can be achieved. This precise control helps ensure that the experimental materials in the mixing barrel obtain the required airflow during the mixing process, thereby improving the mixing efficiency and mixing quality.

[0033] Furthermore, an anti-corrosion layer is fixedly connected to the inner wall of the mixing barrel.

[0034] Beneficial effect: The anti-corrosion layer can isolate the inner wall of the mixing barrel from direct contact with corrosive materials, thereby effectively preventing the inner wall of the mixing barrel from being corroded.

[0035] The presence of the anti-corrosion layer can reduce the friction resistance between the inner wall of the mixing barrel and the material, thereby improving the mixing efficiency.

[0036] Furthermore, a plurality of heat dissipation holes are opened on the surface of the box.

[0037] Beneficial effect: The presence of heat dissipation holes effectively increases the surface area of ​​the box, making it easier for heat to be dissipated to the surrounding environment through air convection or radiation. This helps to reduce the internal temperature of the box and reduce driver failure or performance degradation caused by overheating.

[0038] Furthermore, a heating wire is fixedly connected to the inner wall of the stirring barrel, and when the biological sample is heated, the heating wire is turned on by the controller.

[0039] Beneficial effects: The heating temperature and heating time of the heating wire can be accurately controlled by the controller, thereby achieving accurate temperature control of the experimental materials. The heating wire is directly fixed to the inner wall of the mixing barrel, so that the heat can be quickly and evenly transferred to the experimental materials in the mixing barrel.

[0040] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0047] The following is further described in detail through specific implementation methods:

[0048] Embodiment 1:

[0049] As attached Figure 1-Figure 5 As shown: a gastroenterology experiment stirring device, including a box body 1, a feeding port 2 is opened on the top of the box body 1, a top cover is detachably connected to the feeding port 2, a discharge port is opened on the side wall of the box body 1, a controller is fixedly connected to the surface of the box body 1 by screws, a stirring barrel 3 is fixedly connected to the inner wall of the box body 1 by bolts, the top of the stirring barrel 3 is connected to the feeding port 2, the bottom of the stirring barrel 3 is connected to the discharge port, and a vibration component for vibrating the stirring barrel 3 is provided at the bottom of the stirring barrel 3.

[0050] The bottom wall of the box body 1 is fixedly connected with a first support rod 16 by bolts, and the top of the first support rod 16 is fixedly connected with a driving member by bolts. In this embodiment, the driving member is a double-headed motor 4, and the controller is used to control the start and stop of the double-headed motor 4. One end of the double-headed motor 4 penetrates into the mixing barrel 3 and is provided with a stirring assembly for experimental stirring. The other end of the double-headed motor 4 is fixedly connected with a rotating rod 15 by bolts. Figure 3 As shown, the left end of the rotating rod 15 is fixedly connected to the sliding block 12 via bolts.

[0051] The inner bottom wall of the box body 1 is fixedly connected with a second support rod 9 by bolts, and an "L"-shaped fixing plate 7 is symmetrically fixedly connected to the second support rod 9 by bolts, and the other end of the fixing plate 7 is fixedly connected with a piston cylinder 6 by bolts.

[0052] like Figure 3 As shown, a rack 11 is provided in front of the second support rod 9 , and a sliding groove 13 is fixedly connected to the side wall of the rack 11 by bolts, and the sliding groove 13 is slidably matched with the sliding block 12 .

[0053] Both ends of the rack 11 are fixedly connected with a piston head 20 by bolts, and the piston head 20 is slidably matched with the adjacent piston cylinder 6; Figure 5 As shown, the top of the piston cylinder 6 away from the piston head 20 is provided with an air inlet 23 , and the bottom is provided with an air outlet 21 , and the air outlet 21 is communicated with the mixing barrel 3 .

[0054] The rack 11 is meshed with the gear 5. Figure 2 As shown, a swing component for striking the vibration component is provided on the left side of the gear 5 and penetrates the second support rod 9 .

[0055] like Figure 3 As shown, the stirring assembly includes a stirring rod 17, which is coaxially connected to the output shaft of the double-headed motor 4 by bolts, and a plurality of stirring blades 14 are fixedly connected to the stirring rod 17 by bolts.

[0056] like Figure 3 As shown, the vibration assembly includes a vibration plate 10, and a plurality of springs 19 are fixedly connected to the bottom of the vibration plate 10 by bolts. The ends of the springs 19 away from the vibration plate 10 are fixedly connected to the bottom wall of the box body 1 by bolts, and the top of the vibration plate 10 contacts the bottom of the mixing barrel 3.

[0057] The swing assembly includes a swing plate 8 , which is fixedly connected to the gear 5 by bolts, and a vibration plate 10 is in contact with the swing plate 8 .

[0058] like Figure 5 As shown, the air inlet 23 and the air outlet 21 are both connected to the solenoid valve 22 by means of screws, and the controller is used to control the opening and closing of the solenoid valve 22 .

[0059] The specific implementation process is as follows: First, the staff needs to open the top cover and put the experimental sample into the mixing barrel 3 through the feed port 2.

[0060] by Figure 3 and Figure 4 For example, the staff can start the double-headed motor 4 through the controller, use the output shaft of the double-headed motor 4 to drive the stirring rod 17 to rotate, and use the rotation of the stirring rod 17 to drive the stirring blade 14 to rotate. The rotation of the stirring blade 14 driven by the double-headed motor 4 can efficiently stir the experimental sample in the stirring barrel 3, ensure the uniform mixing of the sample, and improve the accuracy of the experimental results.

[0061] When the double-headed motor 4 is started, the rotating rod 15 will also rotate with the start of the double-headed motor 4. When the rotating rod 15 rotates, it will drive the slider 12 to slide in the sliding groove 13. When the slider 12 continues to move upward under the rotation of the rotating rod 15, the slider 12 will drive the sliding groove 13 to move to the right together. At this time, the rack 11 will also move to the right driven by the sliding groove 13.

[0062] Combination Figure 5 As shown, when the rack 11 moves to the right, the piston head 20 will move to the right in the piston barrel 6. At this time, the solenoid valve 22 of the air inlet 23 is closed by the controller, and the solenoid valve 22 of the air outlet 21 is opened. Then, as the piston head 20 moves to the right in the piston barrel 6, the airflow in the piston barrel 6 will enter the mixing barrel 3 along the air outlet 21. By controlling the opening and closing of the solenoid valve 22 by the controller, the inflow and outflow of the gas in the piston barrel 6 can be accurately controlled, thereby adjusting the airflow in the mixing barrel 3, which is conducive to the full mixing and reaction of the experimental samples and reduces the occurrence of precipitation of the experimental samples during the experiment.

[0063] Combination Figure 3 As shown, when the slider 12 starts to move downward from the top, the rack 11 starts to move to the left. Figure 5 As shown, when the rack 11 moves to the left, the piston head 20 will move to the left in the piston cylinder 6. At this time, the solenoid valve 22 of the air inlet 23 is controlled by the controller to open, and the solenoid valve 22 of the air outlet 21 is controlled by the controller to close. At this time, the air in the environment will enter the piston cylinder 6 through the air inlet 23, waiting for the next compression action of the piston head 20.

[0064] by Figure 2 For example, as the rack 11 moves left and right, the rack 11 will drive the meshed gear 5 to rotate back and forth continuously, and the reciprocating rotation of the gear 5 will drive the swing plate 8 to swing back and forth.

[0065] When the swing plate 8 swings back and forth, it will continuously hit the vibration plate 10. Since the vibration plate 10 is located at the bottom of the mixing drum 3 and in contact with the mixing drum 3, the vibration plate 10 will move downward when hit by the swing plate 8. At this time, the spring 19 is compressed. When the swing plate 8 stops hitting the vibration plate 10, the vibration plate 10 will move upward under the elastic force of the spring 19, so that the mixing drum 3 will continuously vibrate, thereby further improving the stirring effect of the experimental materials in the mixing drum 3. After the stirring of the experimental materials is completed, the experimental materials can be discharged through the discharge port.

[0066] Embodiment 2:

[0067] like Figure 4 As shown, the difference from the above embodiment is that a thread groove 18 for guiding air flow is opened on the inner wall of the mixing barrel 3.

[0068] The specific implementation process is as follows: when blowing air into the mixing barrel 3 through the air outlet 21, the airflow can be better guided by opening a spiral groove 18 on the inner wall of the mixing barrel 3, so that the airflow flows along the spiral groove 18, thereby enhancing the disturbance and mixing effect of the airflow in the mixing barrel 3, further promoting the mixing and uniform distribution of the experimental materials, and reducing the occurrence of precipitation of the experimental materials.

[0069] Embodiment 3:

[0070] The difference from the above embodiment is that the bottom of the mixing barrel 3 is made of elastic material, and in this embodiment, the elastic material is preferably polyurethane material.

[0071] The specific implementation process is as follows: when the vibration plate 10 vibrates, the elastic material can absorb and transmit the vibration energy, so that the mixing barrel 3 produces a corresponding vibration effect. The elastic material at the bottom of the mixing barrel 3 can absorb and transmit the vibration energy, so that the material in the mixing barrel 3 is subjected to a more uniform vibration effect. This helps to break up the agglomerates in the material and improve the mixing uniformity and consistency of the material.

[0072] Embodiment 4:

[0073] The difference from the above embodiment is that the inner wall of the mixing barrel 3 is fixedly connected with an anti-corrosion layer by screws, and in this embodiment, the anti-corrosion layer is preferably made of polyurethane material.

[0074] The specific implementation process is as follows: when the experimental material to be stirred in the mixing barrel 3 is corrosive to a certain extent, an anti-corrosion layer should be used to protect the inner wall of the mixing barrel 3. The anti-corrosion layer can effectively isolate the inner wall of the mixing barrel 3 from direct contact with the corrosive experimental material, thereby slowing down the corrosion and wear of the inner wall of the mixing barrel 3.

[0075] Embodiment 5:

[0076] The difference from the above embodiment is that a plurality of heat dissipation holes are opened on the surface of the box body 1 .

[0077] The specific implementation process is as follows: the double-headed motor 4 will generate heat during operation. If the heat cannot be dissipated in time, the temperature inside the box 1 will increase, which will cause the performance of the double-headed motor 4 to decline, the failure rate to increase, or even damage it.

[0078] By opening the heat dissipation holes, the air circulation inside the box 1 can be increased, the heat dissipation can be accelerated, and the temperature inside the box 1 can be reduced, which helps to maintain the normal operation of the double-headed motor 4 in the box 1 and reduce the failure or damage of the double-headed motor 4 caused by excessive temperature.

[0079] Embodiment 6:

[0080] The difference from the above embodiment is that the inner wall of the stirring barrel 3 is fixedly connected with a heating wire by screws, and when the biological sample is heated, the heating wire is turned on by the controller.

[0081] The specific implementation process is as follows: For experimental materials in gastroenterology, temperature is one of the key factors affecting their physiological activities and chemical reactions. Appropriate temperature conditions can activate enzymes and other biologically active molecules in biological samples, thereby promoting their normal growth, metabolism and reaction processes.

[0082] By accurately controlling the opening and closing of the heating wire through the controller, precise heating and constant temperature control of the experimental materials can be achieved.

[0083] This helps ensure that the experimental materials grow, metabolize or react under appropriate temperature conditions, thereby improving the accuracy and reliability of the experiment.

[0084] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
