Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical experimental technology, specifically to a disintegration apparatus. Background Technology

[0002] Disintegration refers to the physical dissolution process of a drug formulation before absorption. Ordinary tablets should disintegrate completely within 15 minutes, hard capsules within 30 minutes, and soft capsules within 1 hour. Disintegration rate is one of the indicators for evaluating drug quality. It refers to the limit of time required for complete disintegration and passage through a sieve, measured under certain conditions using a testing device specified in the pharmacopoeia, for certain drug dosage forms (tablets, pills, etc.). A disintegration apparatus is a laboratory instrument used to test the disintegration of drugs such as tablets.

The upper end of the glass tube is movably inserted into the inner side of the first through hole. A sealing ring is movably sleeved on the outer wall of the upper end of the connecting column. The sealing ring is located above the limiting ring. A second through hole is provided on the side of the sealing ring. The second through hole communicates with the first through hole. A support leg is fixed on the side of the bottom surface of the water tank. A placement groove is provided in the middle of the top surface of the water tank. The placement groove communicates with the inner side of the water tank. A beaker is movably inserted into the inner side of the placement groove. The beaker is located below the tray.

[0009] As a preferred technical solution of the disintegration device of this utility model, the tray is provided with a threaded hole in the middle, and the second threaded post is threadedly connected to the inside of the threaded hole.

[0010] As a preferred technical solution of the disintegration device of this utility model, a threaded ring is threadedly connected to the outer side of the first threaded column, and the threaded ring is located above the sealing ring.

[0011] As a preferred technical solution of the disintegration device of this utility model, a heating rod is symmetrically fixed on the bottom inner side of the water tank, and the heating rod is located on both sides of the support plate.

[0012] As a preferred technical solution of the disintegration device of this utility model, a drain pipe is fixed on the outer side of one side of the water tank, the drain pipe is connected to the inner side of the water tank, and a sealing plug is movably inserted into the inner side of one end of the drain pipe, the sealing plug being made of flexible material.

[0013] As a preferred technical solution of the disintegration device of this utility model, a display controller is fixed to one side of the top plate, and a timer is fixed to one side of the top plate, with the timer located on one side of the display controller.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention uses a glass tube to hold the drug, which is located above a sieve inside the glass tube. An electric push rod on the bottom of the top plate drives the tray to move downwards, thereby bringing the glass tube into the beaker for disintegration experiments. The lower end of the glass tube is movably inserted into the insertion groove on the tray, and a second fixing ring ensures that the glass tube will not move downwards. The upper end of the glass tube is movably inserted into the first through hole on the limiting ring, and the first fixing ring ensures that the glass tube cannot move upwards, thus fixing the glass tube. By rotating the sealing ring, the second through hole on the sealing ring is staggered with the first through hole, thereby sealing the upper end of the glass tube to prevent drug leakage during the experiment. Furthermore, the glass tube, tray, limiting ring, and sealing ring can all be disassembled, facilitating cleaning after the experiment and improving cleaning efficiency.

[0016] The beaker of this invention passes through the placement groove on the top surface of the water tank and is placed inside the water tank. The heating rod can heat the water in the water tank, so that the temperature of the solution in the beaker reaches the temperature required for drug disintegration. After the solution is injected into the beaker, it presses down on the support plate, pressing down the support plate and support plate. The spring is stretched, and the moving rod moves down. At this time, most of the beaker is located inside the water tank. It is very difficult to take the beaker by grabbing the upper part of the beaker wall. When it is necessary to take out the beaker, simply pull the handle upward to move the moving rod upward, which will cause the support plate to move the support plate upward. The support plate lifts the beaker upward, so that the beaker is removed from the water tank, making it quick and convenient to take out the beaker. Attached Figure Description

[0027] Example

[0028] Please see Figure 1-7As shown, this utility model provides the following technical solution: a disintegration device, including a water tank 1, with support legs 11 fixed to the bottom edge of the water tank 1 to support it. Heating rods 15 (the heating rod 15 is prior art; its specific operation and principle can be referred to in the prior art for electric heating rods used to generate heat and heat the liquid, therefore it is not described in detail here) are symmetrically fixed to the bottom inner side of the water tank 1. The heating rods 15 are located on both sides of a support plate 16. A display controller 21 (the display controller 21 is prior art; its specific operation and principle can be referred to in the prior art for electric heating rods used to generate heat and heat the liquid, therefore it is not described in detail here) is fixed to one side of the top plate 2. The microprogram controller used in the prior art can be used to control the heating rod 15 and the electric push rod 23, so it is not described in detail here. A timer 22 is fixed on one side wall of the top plate 2 (the timer 22 is the prior art, and the specific operation mode and principle can be referred to the electronic stopwatch in the prior art, which is used to accurately record time, so it is not described in detail here). The timer 22 is located on one side of the display controller 21. In this scheme, the heating rod 15 heats the water inside the water tank 1, thereby heating the experimental solution in the beaker 3 to ensure a suitable experimental temperature.

[0029] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, specifically, a fixing plate 14 is fixed to the edge of the top surface of the water tank 1 to support the top plate 2. The top plate 2 is fixed to the top of the fixing plate 14, which can fix structures such as the electric push rod 23. The electric push rod 23 is fixed to the middle of the bottom surface of the top plate 2 (the electric push rod 23 is existing technology; its specific operation and principle can be referred to in the existing small electric push rod device, which is controlled by the display controller 21, so it is not described in detail here). The lower end of the electric push rod 23 is fixed with a first threaded post 231 for connecting the connecting post 232 and the threaded ring 28. The lower end of the first threaded post 231 is fixed with a connecting post 232 for connecting the second threaded post 233, the limiting ring 25, and the sealing ring 26. The lower end of the connecting post 232 is fixed with... The second threaded post 233 can be threadedly connected to the tray 24 to fix the tray 24. The tray 24 is threadedly connected to the outer side of the second threaded post 233 to support the glass tube 27. The tray 24 has a threaded hole 241 in the middle for threaded connection between the tray 24 and the second threaded post 233. The second threaded post 233 is threaded inside the threaded hole 241. The tray 24 has an insertion groove 242 on its side for inserting and placing the glass tube 27. The glass tube 27 is movably inserted into the insertion groove 242, which can hold the drug to be disintegrated. A sieve 273 is fixed to the inner wall of the lower end of the glass tube 27 to support the drug. The time it takes for the drug to pass through the sieve 273 after disintegration is observed and the experimental data is recorded. A second fixing ring 272 is fixedly sleeved on the outer wall of the glass tube 27 to prevent it from falling. The second fixing ring 272 is located above the tray 24. A first fixing ring 271 is fixedly sleeved on the outer wall of the upper end of the glass tube 27 to prevent it from moving upward. A limiting ring 25 is movably sleeved on the outer side of the upper end of the connecting post 232 to limit the upper part of the glass tube 27. The limiting ring 25 is located above the first fixing ring 271. A first through hole 251 is provided on the side of the limiting ring 25 for connecting the glass tube 27. The upper end of the glass tube 27 is movably inserted into the inner side of the first through hole 251. A sealing ring 26 is movably sleeved on the outer wall of the upper end of the connecting post 232 to seal the glass tube 27 and prevent drug leakage during the experiment. The sealing ring 26 is located on the limiting ring 25. The sealing ring 26 has a second through hole 261 on its side, through which drugs can be put into the inside of the glass tube 27. The second through hole 261 communicates with the first through hole 251. A threaded ring 28 is threadedly connected to the outside of the first threaded post 231. The threaded ring 28 presses against the sealing ring 26, which can restrict the movement or rotation of the sealing ring 26. The threaded ring 28 is located above the sealing ring 26. In this scheme, the glass tube 27 is driven to move down into the beaker 3 by the electric push rod 23 to conduct the drug disintegration experiment. The glass tube 27, tray 24, limiting ring 25 and sealing ring 26 can all be disassembled, which greatly facilitates the cleaning of related structures after the experiment and prepares for the next experiment. This facilitates the experimental operation of the staff and can improve efficiency.

[0030] Reference Figure 1 , Figure 2 and Figure 7 As shown, specifically, a placement groove 17 is provided in the middle of the top surface of water tank 1 for placing beaker 3 into the inside of water tank 1 and adding water to water tank 1. The placement groove 17 is connected to the inside of water tank 1, and beaker 3 is movably inserted into the inside of placement groove 17 to contain the solution used in the drug disintegration experiment. Beaker 3 is located below tray 24. A support plate 16 is provided in the middle of the inside of water tank 1 to support and fix support plate 161. Support plate 161 is fixed in the middle of the top surface of support plate 16 to support beaker 3. To prevent beaker 3 from falling completely into the water tank 1, a support plate 161 is located below beaker 3. A movable rod 162 is symmetrically fixed to the top surface of the support plate 16, allowing the support plate 16 to move. The movable rod 162 is located on both sides of the support plate 161. A movable hole 18 is symmetrically provided on the top surface of the water tank 1 for the movable rod 162 to move up and down. The movable hole 18 communicates with the inside of the water tank 1 and is located on both sides of the placement slot 17. The movable rod 162 passes through the movable hole 18. A spring 164 is movably sleeved on the outside. The spring 164 slowly stretches as the beaker 3 moves downwards, preventing it from falling rapidly and spilling the solution. The upper end of the spring 164 is fixed to the inner wall of the water tank 1, and the lower end is fixedly connected to the support plate 16. A handle 163 is fixed to the top of the moving rod 162. The handle 163 allows for easy upward pulling of the moving rod 162 while preventing it from completely entering the water tank 1. In this design, after the beaker 3 is filled with solution, it can be... When the beaker 3 is placed inside the water tank 1 through the placement slot 17, it will press the support plate 161 to move downward. The support plate 161 will drive the support plate 16 to move downward, and the support plate 16 will drive the moving rod 162 to move downward, so that the spring 164 will gradually stretch, ensuring that the beaker 3 moves downward slowly and preventing the solution from spilling. By pulling the handle 163 upward, the moving rod 162 can be moved upward, thereby causing the support plate 161 to move the beaker 3 upward, making it easy to remove the beaker 3 from the inside of the water tank 1, which facilitates the experimental operation.

[0031] Reference Figure 1 and Figure 2 As shown, specifically, a drain pipe 12 is fixed to the outer side of one side of the water tank 1 for draining the water in the water tank 1. The drain pipe 12 is connected to the inside of the water tank 1. A sealing plug 13 is movably inserted into the inside of one end of the drain pipe 12. The sealing plug 13 is made of flexible material and can seal the drain pipe 12. In this scheme, water is added to the inside of the water tank 1 through the placement groove 17, and the water after use is discharged through the drain pipe 12, which provides convenience for the addition and discharge of experimental water.

[0032] The working principle and usage process of this utility model:

[0033] When in use, fill the inside of the water tank 1 with water, add the solution required for disintegrating the drug to the beaker 3, and then place the beaker 3 inside the placement slot 17. The weight of the beaker 3 presses on the support plate 161. The support plate 161 moves down, causing the support plate 16 to move down. The spring 164 gradually stretches, allowing the beaker 3 to slowly move down until most of it enters the inside of the water tank 1. Then, the display controller 21 (the display controller 21, the electric push rod 23 and the heating rod 15 are connected by wires, which are not shown in the figure) controls the heating rod 15 to heat the water, so that the solution in the beaker 3 rises to a suitable temperature.

[0034] The drug to be disintegrated is placed inside the glass tube 27 through the second through hole 261, with the drug above the sieve 273. Then, the sealing ring 26 is rotated so that the second through hole 261 and the first through hole 251 are staggered, thereby sealing the top of the glass tube 27 with the sealing ring 26 to prevent drug leakage. Then, the threaded ring 28 is turned and rotated downward to press the sealing ring 26 and fix it. Finally, the display controller 21 controls the electric push rod 23 to drive the glass tube 27 downward into the beaker 3, and the drug disintegration time is observed. The timer 22 can be used to record the time data.

[0035] After the experiment is completed, the electric push rod 23 moves the glass tube 27 above the beaker 3. By rotating the threaded ring 28 in the opposite direction, the threaded ring 28 is moved upward. Then, the limiting ring 25 and the sealing ring 26 are moved upward, so that the glass tube 27 is disengaged from the first through hole 251. Then, the tray 24 is rotated to separate the tray 24 from the second threaded post 233 (the second threaded post 233 is threadedly connected to the inside of the threaded hole 241 in the middle of the tray 24), so that the tray 24 can be disassembled. Then, the glass tube 27 is taken out from the inside of the insertion slot 242 on the tray 24. Then, the limiting ring 25 and the sealing ring 26 are moved downward and disassembled, so that the relevant structure can be easily cleaned. By pulling the handle 163, the moving rod 162 is moved upward, which compresses the spring 164, so that the support plate 161 moves the beaker 3 upward, making it easy to take the beaker 3 out from the inside of the water tank 1.

[0036] 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.
