Description

Technical Field

[0001] The invention relates to the technical field of medicine grinding, in particular to a medicine grinder for pediatric care. Background Art

[0002] Medicine grinding is to improve the solubility, absorbability, efficacy and ease of preparation and administration of medicines. Children, especially infants, have difficulty swallowing whole tablets or large pieces of medicines. After grinding, the medicines become finer and easier to prepare and take. Currently, there are few children-specific dosage forms on the market. Grinding adult medicines has become a way to meet children's medication needs. For medicines that require precise dosage control, grinding can better distribute the medicine and ensure that children get the exact dosage.

[0003] During the grinding process, the appropriate grinding particle size should be selected according to the characteristics of the drug and the requirements of use. For some drugs with strict requirements on the particle size, excessive grinding may destroy the active ingredients of the drug. It is not easy to adjust the degree of crushing according to the dosage of the drug. Moreover, it is not easy to control the temperature during the crushing process. If the dosage of the drug is large and the temperature rises too quickly after friction with the crushing shaft, it may cause decomposition reaction of the active ingredients of the drug. Moreover, too fast heating may also cause chemical reactions of certain components in the drug to generate harmful impurities, which will affect the medicinal properties of the drug and reduce the use effect. For this reason, we propose a drug grinder for pediatric care. Summary of the invention

The upward movement of the adjusting component 8 realizes the adjustment of the rotation speed and the heat dissipation speed of the crushing blade 14, and realizes the adjustment of the crushing speed and the heat dissipation speed according to the number of tablets, thereby reducing the risk of the tablets heating up too quickly after crushing and affecting the medicinal properties.

[0042] The medicine feeding component 3 includes a medicine pushing plate 31 arranged at the bottom of the medicine feeding chamber 21, and a connecting plate 1 32 is arranged on the side of the medicine pushing plate 31, a pressing block 1 33 is fixed to the bottom of the connecting plate 1 32, and a pressing block 2 34 is pressed against the bottom of the pressing block 1 33, and a baffle 35 is fixed to the side of the pressing block 2 34, and the bottom of the pressing block 2 34 is slidably connected to the operating chamber 22 through a slider 38, a medicine outlet 36 cooperating with the baffle 35 is opened inside the operating chamber 22, and a medicine outlet chamber 37 is opened at the bottom of the medicine outlet 36, and a slide groove 39 cooperating with the slider 38 is opened inside the operating chamber 22 The bottom of the pressing block 1 33 is slidably connected to the surface of the pressing block 2 34 through a sliding ball, and a sliding cavity cooperating with the sliding ball is provided inside the pressing block 2 34. The design of the sliding ball and the sliding cavity facilitates the movement of the pressing block 1 33 against the pressing block 2 34. When the pressing block 1 33 moves up, the sliding ball pulls the pressing block 2 34 to reset, thereby driving the baffle 35 to reset and block the medicine outlet 36 again. The medicine pushing plate 31 pushes a single tablet to fall, preventing the tablet from being stuck inside the medicine outlet 36. At the same time, the next group of tablets is blocked to prevent the next group of tablets from falling synchronously with the falling tablets.

[0043] The pressing assembly 4 includes an insertion rod 41 fixed on the top of the connecting plate 32, and an insertion tube 43 is fixed on the top of the insertion rod 41. A spring 42 is sleeved on the outside of the insertion rod 41, and a pressing plate 44 is fixed on the top of the insertion tube 43. Pressing the pressing plate 44 downward once pushes the single group of tablets to fall, thereby realizing the feeding operation of the single group of tablets.

[0044] When it is necessary to crush the tablets, first, press the pressing plate 44 downward, and the pressing plate 44 pushes the insertion tube 43 and the insertion rod 41 to move downward synchronously. The spring 1 42 is in a compressed and force-accumulating state, and the insertion rod 41 pushes the connecting plate 1 32 to move downward. The downward movement of the connecting plate 1 32 drives the medicine pushing plate 31 to move downward synchronously, and the medicine pushing plate 31 pushes the medicine inside the medicine outlet 36 to move downward. At the same time, the downward movement of the connecting plate 1 32 drives the pressing block 1 33 to move downward synchronously. The downward movement of the pressing block 1 33 drives the pressing block 2 34 to move away from the medicine outlet 36, and the pressing block 2 34 drives the baffle 35 to move away from the medicine outlet 36. The blocking of the baffle 35 on the medicine outlet 36 is released, and the tablet falls into the medicine outlet cavity 37 under the push of the medicine pushing plate 31, realizing the feeding operation of a single tablet.

[0045] The operating component 15 includes a connecting plate 2 51 fixed to the side of the connecting plate 1 32, and a rack plate 1 52 is fixed to the side of the connecting plate 2 51, and a gear 1 53 is meshed on the side of the rack plate 1 52, and a ratchet groove 54 is provided inside the gear 1 53, and a rotating disk 55 is provided inside the ratchet groove 54, and a rotating rod 1 56 is fixed to the center of the rotating disk 55, and a rotating shaft 1 57 is fixed on the surface of the rotating disk 55, and a ratchet pawl 58 is rotatably connected to the surface of the rotating shaft 1 57, and the ratchet pawl 58 is pressed against the inside of the ratchet groove 54, and a spring 2 59 is fixed on the side of the ratchet pawl 58. 5 is convenient for driving the one-way rotation of the gear 2 69. In the process of controlling the medicine to fall, the rack plate 1 52 moves down, which indirectly drives the gear 2 69 to rotate. When the rack plate 1 52 returns to its original position, it will not indirectly drive the gear 2 69 to rotate, so that it is convenient to adjust the rotation angle of the gear 2 69 according to the number of tablets, thereby controlling the upward movement distance of the rack plate 2 62 and the docking ring 1 63. The longer the rising distance of the docking ring 2 64 is, the longer the descending time of the docking ring 2 64 is, which indirectly makes the tablet crushing time longer. The crushing time is adjusted according to the number of tablets input, so that the medicine reaches a suitable crushing range.

[0046] The operating assembly 26 includes a gear 269 fixed to the outer wall of the rotating rod 156, and a rack plate 262 is meshed on the side of the gear 269, a rotating shaft 261 is fixed to the surface of the rotating disk 55, the end face of the spring 269 is connected to the rotating shaft 261, the rack plate 262 is fixed to the surface of the docking ring 163, a docking ring 264 is fixed to the inner wall of the docking ring 163, and a threaded ring 68 is threadedly connected to the inner wall of the docking ring 264, and the bottom of the threaded ring 68 is rotatably connected to the inside of the tank body 11, and the two groups of docking rings 163 are connected by a rubber plate 65, an electromagnet 66 is fixed to one end of the docking ring 264, and a metal sheet 67 is fixed to the other end of the docking ring 264, and the number of teeth of the gear 269 is less than the number of teeth on the outer wall of the gear 153, so as to facilitate the adjustment of the crushing time of the crushing leaf 14 according to the number of tablets input, reduce the risk of excessive or incomplete crushing of the tablets, if excessive crushing may destroy the dosage form of the medicine, so that the contact area between the medicine and the external environment is increased If the tablets are not completely crushed, the dissolution rate of larger drug particles in the gastrointestinal tract will slow down. Some compound tablets contain multiple drug ingredients. Incomplete crushing may cause uneven mixing of the ingredients. For children, especially young children, who have limited swallowing ability, incompletely crushed drugs may have larger particles, which can cause swallowing difficulties and increase children's resistance to taking medicine. If children cannot take the medicine smoothly, it may affect the timeliness and compliance of treatment. Therefore, the crushing time should be reasonably adjusted according to the number of tablets. By controlling the crushing time, the drug can reach an appropriate particle size range, which is conducive to children's taking and absorption.

[0047] The rotating assembly 7 includes a rack ring 71 fixed to the inner wall of the threaded ring 68, and the inner wall of the rack ring 71 is rotatably connected to a gear 3 72, a rotating rod 2 73 is fixed to the center of the gear 3 72, a gear 4 74 is meshed on the side of the gear 3 72, a rotating rod 3 75 is fixed to the center of the gear 4 74, the bottom of the rotating rod 3 75 is fixed to the crushing leaf 14, the outer wall of the rotating rod 3 75 is rotatably connected to a partition 1 76, the outer wall of the partition 1 76 is fixed to the inner wall of the tank cover 12, a medicine inlet groove 77 is provided inside the partition 1 76, and the partition 1 76 is provided with a medicine inlet groove 77. 6 is provided with a partition plate 2 78 at the bottom, and the outer wall of the partition plate 2 78 is fixed inside the can cover 12. When the crushing blade 14 rotates and works, the threaded ring 68 is driven to rotate through the rotating component 7 to realize the rotation and reset of the docking ring 2 64. The more tablets are put in, the longer the upward movement distance of the docking ring 2 64 is, the longer the rotation and reset time is, and the longer the crushing time is. The rotation of the crushing blade 14 indirectly drives the docking ring 2 64 to reset, and the synchronous operation is more coordinated, which reduces the cost of power equipment, saves space, and improves energy utilization efficiency.

[0048] When a single group of tablets falls, the connecting plate 1 32 drives the connecting plate 2 51 to move downward synchronously, the connecting plate 2 51 drives the rack plate 1 52 to move downward synchronously, the rack plate 1 52 moves downward and drives the gear 1 53 to rotate clockwise, the gear 1 53 rotates clockwise, the pawl 58 presses against the inside of the ratchet groove 54, drives the turntable 55 to rotate clockwise synchronously, the turntable 55 drives the rotating rod 1 56 to rotate synchronously, the two ends of the rotating rod 1 56 are rotatably connected to the inner wall of the operating chamber 22, the rotation of the rotating rod 1 56 drives the gear 2 69 to rotate synchronously, the gear 2 69 rotates clockwise and drives the rack plate 2 62 to rotate upward The rack plate 2 62 moves upward, driving the docking ring 1 63 to move upward synchronously. At this time, the electromagnet 66 is not energized, the rubber plate 65 is in a normal state, the two groups of docking rings 2 64 are disconnected, the fitting state between the inner wall of the docking ring 2 64 and the threaded ring 68 is released, the docking ring 1 63 moves upward, driving the docking ring 2 64 to move upward synchronously, and the docking ring 2 64 moves upward on the surface of the threaded ring 68. If the pressing plate 44 is pressed once, the docking ring 2 64 rises one scale mark, and the rising distance of the docking ring 2 64 is proportional to the number of times the pressing plate 44 is pressed, thereby realizing the counting operation of tablet feeding.

[0049] When the tablet feeding is completed, the crushing leaf 14 starts to work, and the controller synchronously controls the electromagnet 66 to be energized. The electromagnet 66 generates magnetism when it is energized. Under the action of magnetism, the electromagnet 66 is adsorbed with the metal sheet 67 to achieve the docking and fixation of the two groups of docking rings 64, and drive the two groups of docking rings 1 63 to approach each other. The rubber plate 65 is in a compressed and bent state, and the inner wall of the docking ring 2 64 is pressed against the surface of the threaded ring 68. The rotating tube 16 rotates and works, and the rotating tube 16 drives the rotating rod 3 75 to rotate synchronously. The rotating rod 3 75 drives the gear 4 74 to rotate synchronously. The rotation of the gear 4 74 drives the gear 3 72 to rotate synchronously. The rotation of the gear 3 72 drives the rack ring 71 to rotate. The rotation of the rack ring 71 drives the threaded ring 68 to rotate synchronously. With the cooperation of the inner wall thread of the docking ring 2 64, the threaded ring 68 rotates and drives the docking ring 2 64 to move downward.

[0050] The adjustment component 8 includes a moving plate 1 81 and a moving plate 2 84 fixed on both sides of the rack plate 2 62, a sliding piece 1 82 is fixed on the side of the moving plate 1 81, and the sliding piece 1 82 is slidably connected to the surface of the sliding rheostat 1 83, and the two ends of the sliding rheostat 1 83 are fixed inside the operating chamber 22, a sliding piece 2 85 is fixed on the side of the moving plate 24, and the sliding piece 2 85 is slidably connected to the surface of the sliding rheostat 2 86, and the two ends of the sliding rheostat 2 86 are fixed inside the operating chamber 22, a pressing switch 87 matched with the threaded ring 68 is fixed at the bottom of the operating chamber 22, and a push-type buzzer 88 matched with the threaded ring 68 is fixed at the top of the operating chamber 22. When the push-type buzzer 88 is pressed, a warning is issued. Its working principle is mainly based on electromagnetic induction. It has an oscillation circuit and a sounding element such as a piezoelectric ceramic piece inside. When the button is pressed, the circuit is connected, and the current passes through the oscillation circuit to generate a signal of a specific frequency, driving the sounding element to vibrate, thereby emitting a "beep". The sound is heard to warn the operator, indicating that the capacity of the tablets loaded inside the tank body 11 has reached the upper limit and it is not easy to put them in again. When the pressure switch 87 is pressed, the signal is transmitted to the controller, which controls the power source of the crushing leaves 14 and the heat dissipation leaves 91 to stop working, indicating that the medicine crushing working time has ended.

[0051] The more times you press, the longer the rack plate 62 rises. The rack plate 62 rises and drives the moving plate 1 81 and the moving plate 2 84 to move up synchronously. The resistance value of the sliding rheostat 1 83 is adjusted by the movement of the moving plate 1 81, and the resistance value of the sliding rheostat 2 86 is adjusted by the movement of the moving plate 2 84. When the slider 1 82 moves up, the resistance value of the sliding rheostat 1 83 is smaller, and when the slider 2 85 moves up, the resistance value of the sliding rheostat 2 86 is larger. After the external power supply is connected, the sliding rheostat 1 83 and the crushing leaf 1 4, the sliding rheostat 1 83 and the sliding rheostat 2 86 are adapted to the rotation speed of the heat dissipation leaf 91. If the number of tablets to be crushed is large, the initial crushing speed of the crushing leaf 14 is slow, and the initial heat dissipation speed of the heat dissipation leaf 91 is fast.
