A high-efficiency mixing device for pharmaceutical testing

Abstract

This utility model belongs to the field of pharmaceutical testing technology, and in particular to a high-efficiency mixing device for pharmaceutical testing. It includes a base and a rotating plate. A rotary lifting mechanism for driving the rotating plate to rotate and move up and down is installed on the top of the base. A clamping mechanism for fixing pharmaceutical test tubes is installed on the top of the rotating plate. The rotary lifting mechanism includes a rotating shaft rotatably connected to the top of the base via bearings. This utility model, by providing a clamping mechanism for fixing multiple sets of pharmaceutical test tubes on the top of the rotating plate, allows the test tubes to rotate and move up and down via the rotary lifting mechanism installed on the base when they are clamped at a 45-degree angle. Because the liquid surface is tilted at a 45-degree angle, the contact area between the liquid and the inner wall of the test tube is increased. Furthermore, when the rotary lifting mechanism drives the tilted test tubes to rotate, the liquid is rapidly mixed under the combined action of centrifugal rotation and up-and-down movement.

Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical testing technology, specifically to a high-efficiency mixing device for pharmaceutical testing. Background Technology

[0002] In experimental procedures in fields such as medicine, biology, chemistry, and pharmaceutical testing, it is often necessary to thoroughly mix two or more solutions in a test tube. The mixing effect of the solutions directly affects the accuracy of subsequent experimental data, the sufficiency of the reaction, and the reliability of the test results. It is one of the key links to ensure the smooth conduct of the experiment and the validity of the results.

[0003] In pharmaceutical testing, to ensure initial mixing of the solutions, researchers often use manual shaking to mix the solutions in test tubes. However, when the experiment requires mixing multiple solutions simultaneously or in batches, manual shaking requires researchers to operate on each solution individually, which is cumbersome and time-consuming, significantly reducing testing efficiency. Furthermore, manual shaking can easily lead to insufficient mixing and large local concentration differences among the solutions, thus affecting subsequent pharmaceutical testing data. Therefore, we propose a high-efficiency mixing device for pharmaceutical testing to solve the above problems. Utility Model Content

[0005] (II) Technical Solution To achieve the above objectives, this utility model specifically adopts the following technical solution: A high-efficiency mixing device for pharmaceutical testing includes a base and a rotating plate. The top of the base is equipped with a rotary lifting mechanism for driving the rotating plate to rotate and move up and down. The top of the rotating plate is equipped with a clamping mechanism for fixing pharmaceutical test tubes. The rotating lifting mechanism includes a rotating shaft rotatably connected to the top of the base via bearings. The top end of the rotating shaft is fixedly connected to the bottom of the rotating plate. Four guide cylinders are fixedly fixed to the top of the base. Guide rods are slidably connected inside each guide cylinder. A spring is fixed to the top of the base on one side of each guide rod. The top ends of the four guide rods and the top ends of the four springs are fixedly connected to the bottom of the rotating plate. A convex ring is fixed to the top of the base. Two convex plates that are adapted to the convex ring are fixed to the bottom of the rotating plate.

[0006] Furthermore, the clamping mechanism includes a piston cylinder fixed to the top of the rotating plate, a piston plate slidably connected inside the piston cylinder, an electric push rod fixed to the top of the piston cylinder, the protruding end of the electric push rod slidably through the piston cylinder and extends into its interior and is fixedly connected to the piston plate, and placement cylinders are fixedly arranged in a ring array on the top of the rotating plate, each placement cylinder having an airbag sleeve fixed inside, and air pipes fixedly connected to the inlet and outlet ends of each airbag sleeve, the other end of each air pipe passing through the corresponding placement cylinder and extending to its exterior, and the other end of each air pipe being fixedly connected to the inlet and outlet ends of the piston cylinder.

[0007] Furthermore, each of the two through holes at the top of the piston cylinder has a slidable positioning rod, and the bottom end of each positioning rod is fixedly connected to the top of the piston plate.

[0008] Furthermore, four mounting blocks are fixed on the base, and rotating blocks are rotatably connected between the inner walls of both sides of the mounting blocks via pins. An electric suction cup is fixed to one side wall of each rotating block. Four magnets for fixing the rotating blocks are fixed on the base, and the magnets attract the corresponding rotating blocks respectively.

[0009] Furthermore, two handles are fixed to the top of the base, and the surface of each handle is fixed with a sponge sleeve.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a high-efficiency mixing device for pharmaceutical testing, which has the following beneficial effects: This invention features a clamping mechanism on the top of a rotating plate for fixing multiple sets of liquid test tubes. When the test tubes are clamped at a 45-degree angle, a rotating lifting mechanism mounted on the base can rotate and shake the test tubes. Because the liquid surface is tilted at a 45-degree angle, the contact area between the liquid and the inner wall of the test tube is increased. Furthermore, when the rotating lifting mechanism rotates the tilted test tubes, the liquid can be quickly mixed under the combined effects of centrifugal rotation and shaking. In addition, the clamping mechanism has a self-adjusting function, which can be used to limit and fix test tubes of different diameters. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example like Figure 1 and Figure 2 As shown in the figure, an embodiment of the present invention provides a high-efficiency mixing device for drug testing, including a base 1 and a rotating plate 2. Two handles 9 are fixed on the top of the base 1, and the surface of each handle 9 is fixed with a sponge sleeve. The handles 9 facilitate the operation of the mixing device by the staff, and the sponge sleeve enhances the comfort of the hand when in contact with the handles 9. A rotary lifting mechanism 3 for driving the rotating plate 2 to rotate and move up and down is installed on the top of the base 1, and a clamping mechanism 4 for fixing the drug test tubes is installed on the top of the rotating plate 2. The rotary lifting mechanism 3 includes a rotating shaft 31 rotatably connected to the top of the base 1 via a bearing. The top end of the rotating shaft 31 is fixedly connected to the bottom of the rotating plate 2. Four guide cylinders 32 are fixedly fixed to the top of the base 1. Guide rods 33 are slidably connected inside each guide cylinder 32. A spring 34 fixed to the top of the base 1 is provided on one side of each guide rod 33. Telescopic protective covers 10 are provided on the outer side of each of the four springs 34. The bottom end of each telescopic protective cover 10 is fixedly connected to the top of the base 1. The top end of each telescopic protective cover 10 is fixedly connected to the bottom of the rotating plate 2. This can protect the springs 34, reduce the impact of the external environment on them, and thus extend their service life. The top ends of the four guide rods 33 and the top ends of the four springs 34 are fixedly connected to the bottom of the rotating plate 2. A protruding ring 35 is fixed to the top of the base 1. Two protruding plates 36 that are adapted to the protruding ring 35 are fixed to the bottom of the rotating plate 2. The working principle and usage of this utility model are as follows: In use, multiple sets of liquid test tubes are placed on the clamping mechanism 4 and fixed at a 45-degree angle. Since a motor is installed on the base 1, its output end is fixedly connected to the bottom end of the rotating shaft 31. After starting the motor, the rotating shaft 31 will rotate, causing the four guide cylinders 32 to rotate. Because the four guide rods 33 fixed to the bottom of the rotating plate 2 are respectively limited and slid inside the guide cylinders 32, the rotating plate 2 can be rotated, thereby causing the tilted and fixed test tubes to rotate. When the rotating plate 2 rotates, it will drive two... The convex plate 36 rotates, and the two convex plates 36 rotate on the convex ring 35. When the convex plate 36 rotates to the protrusion on the convex ring 35, it and the rotating plate 2 will be lifted up, and the spring 34 will be in a stretched state. When it rotates to the groove between the two protrusions, the rotating plate 2 can be driven to reset under the reset force of the spring 34. This process is repeated, so that the medicine test tube fixed on the top of the rotating plate 2 can be driven to shake up and down during centrifugal rotation without manual operation. Therefore, the medicine inside the medicine test tube can be quickly mixed.

[0016] like Figure 1 , Figure 3 and Figure 4As shown, in some embodiments, the clamping mechanism 4 includes a piston cylinder 41 fixed to the top of the rotating plate 2. A piston plate 42 is slidably connected inside the piston cylinder 41. The piston plate 42 is composed of a metal plate and a sealing ring, and the sealing ring is tightly fitted to the inner wall of the piston cylinder 41. Positioning rods 47 are slidably installed inside two through holes at the top of the piston cylinder 41. The bottom ends of the positioning rods 47 are fixedly connected to the top of the piston plate 42, which can provide positioning and guidance for the piston plate 42, thus preventing it from shifting left or right during its vertical sliding, thereby enhancing its stability during vertical sliding. An electric push rod 43 is fixed to the top of the piston cylinder 41. The electric push rod 43 is wirelessly controlled and will not be interfered with when it rotates with the rotating plate 2. Furthermore, the electric push rod 43 has a self-locking function, which can prevent the clamped test tube from loosening due to the upward movement of the piston plate 42 during rotation. The protruding end of the electric push rod 43 slides through the piston cylinder 41 and extends into its interior, where it is fixedly connected to the piston plate 42. The top of the rotating plate 2 is fixed with placement cylinders 44 in a circular array. Each placement cylinder 44 has an airbag sleeve 45 fixed inside. The inlet and outlet ends of each airbag sleeve 45 are connected to and fixed with an air tube 46. The other end of each air tube 46 passes through the corresponding placement cylinder 44 and extends to its exterior. The other end of each air tube 46 is connected to and fixed to the inlet and outlet ends of the piston cylinder 41. In use, after inserting the test tubes into the airbag sleeves 45, activating the electric push rod 43 pushes the piston plate 42 downwards. After the piston plate 42 moves downwards... The gas inside the compressible piston cylinder 41 can be sent to the inside of the air bladder sleeve 45 through the air pipe 46. When the air bladder sleeve 45 is inflated, it can clamp and fix the test tube. After the mixture is mixed, the electric push rod 43 is activated again to retract the top end, which drives the piston plate 42 to move upward. At this time, the air bladder sleeve 45 can release the restriction on the test tube, and then the staff can remove the test tube. Because the air bladder sleeve 45 has adjustable inflation, it can clamp and fix test tubes of different diameters.

[0017] like Figure 1As shown, in some embodiments, four mounting blocks 5 are fixed on the base 1. Rotating blocks 6 are rotatably connected between the inner walls of both sides of the mounting blocks 5 via pins. An electric suction cup 7 is fixed to one side wall of each rotating block 6. Four magnet blocks 8 are fixed on the base 1 for fixing the rotating blocks 6. The magnet blocks 8 are attracted to the corresponding rotating blocks 6. In use, when the base 1 is placed on a smooth workbench, the rotating blocks 6 can be rotated open. When the rotating blocks 6 are opened, the electric suction cup 7 will contact the surface of the workbench. Then, the electric suction cup 7 can be operated to firmly adhere to the workbench, preventing the mixing device from shifting during use. If it is necessary to fold the rotating blocks 6, simply rotate them back to their original position. After they are rotated back to their original position, the iron rotating blocks 6 will be attracted and fixed to the magnet blocks 8, thus preventing the rotating blocks 6 from automatically flipping and shifting downwards.

[0018] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
