Description

Technical Field

[0001] This invention relates to the field of medicine crushing devices, specifically a medicine crushing device for nursing care. Background Technology

[0002] Patients in intensive care units are usually unable to swallow pills on their own. In such cases, medical staff need to crush the pills, prepare a powder, and then administer it to the patient. A pill crushing device is required when crushing the pills.

[0003] Currently, most medication crushing devices on the market can only crush medications by squeezing, resulting in incomplete pulverization and affecting subsequent patient administration. Related technologies, by incorporating a motor, pestle, filter, and grinding chamber, allow for easy crushing of tablets within the grinding chamber using leverage. The motor then drives the pestle to rotate and grind the tablets into powder. A filter helps drain the powdered medication, and the pressure plate can rotate around its axis. A cleaning head at the other end of the motor cleans the grinding chamber. While this method achieves good grinding results, it lacks the function of pre-crushing tablets and has limited functionality, reducing its practicality and inconvenience, thus hindering medication crushing operations. Summary of the Invention

[0042] When using, place the tablet in the crushing hopper, crush it by squeezing, and then pour out the crushed powder.

[0043] In related technologies, by setting up a motor, a pestle head, a filter screen, and a grinding tank, the tablets inside the grinding tank can be crushed with minimal force through leverage. Then, driven by the motor, the pestle head can rotate to grind the tablets into powder. The filter screen can promptly drain the ground powder, and the pressure plate can rotate around its own axis. The grinding tank can be cleaned with a cleaning head at the other end of the motor. Although this can achieve a good grinding effect, in actual use, it lacks the function of pre-crushing tablets and requires an external power supply or a built-in power supply to power the motor, reducing the practicality of the device, increasing costs, and making it inconvenient to use, thus causing inconvenience in the crushing of medicine.

[0044] To address some of the problems in related technologies, this application provides a medication crushing device for nursing care. When medication needs to be crushed, simply rotate the mounting plate 13 to allow the ball 23 to slide towards the center of the placement plate 15 while simultaneously rotating the ball 23 via the steering mechanism 21 and the transmission mechanism 25 to grind the medication. Before rotation, the medication is pre-divided by the dividing component 3. Finally, during rotation, the rectangular plate 32 is squeezed by the limiting plate 7, resulting in a better crushing effect on the medication. This device is more convenient and faster, improving the ease of use of the device.

[0045] This application is described below with reference to the accompanying drawings and specific embodiments:

[0046] Combination Figures 1-7 This application provides a nursing medicine crushing device, including a frame assembly 1; the frame assembly 1 includes: a base 11 on which a vertical plate 12 is disposed; a shaft 14 rotatably connected to the vertical plate 12; a mounting plate 13 fixedly connected to the vertical plate 12; a placement plate 15 disposed on the base 11; a grinding assembly 2 disposed on the mounting plate 13; the grinding assembly 2 includes: a steering mechanism 21 disposed on the mounting plate 13; a rod 22 disposed within the steering mechanism 21; a ball 23 fixedly connected to one end of the rod 22; and a motor 24 disposed on the base 11. The mounting plate 13 is equipped with a transmission mechanism 25, which is disposed on the mounting plate 13. The shaft 14 is connected to the motor 24 and the rod 22 via the transmission mechanism 25 and the rod 22. The placement plate 15 is provided with a dividing component 3. The dividing component 3 includes: a knife groove 31, which is formed on the placement plate 15; a rectangular plate 32, which is disposed on the placement plate 15; and a cutter 33, which is fixedly connected to the rectangular plate 32 and is embedded in the knife groove 31. The mounting plate 13 is provided with a limiting plate 7, which is in close contact with the rectangular plate 32.

[0047] In use, after placing the base 11 in the designated position, place the tablet in the groove at the center of the placement plate 15. Then, align the rectangular plate 32 with the placement plate 15 and press down on the rectangular plate 32, causing it to drive the cutter 33 to slide into the blade groove 31. After the cutter 33 contacts the tablet, it performs the function of cutting the tablet. Then, let the cutter 33 slide completely into the blade groove 31. Finally, hold the mounting plate 13 and turn on the motor 24. Through the output end of the motor 24, the steering mechanism 21, and the transmission mechanism 25, the rod 22 is driven to rotate. As the rod 22 rotates, it drives the... The rotating ball 23 causes the mounting plate 13 to rotate, and at the same time, the ball 23 rotates on its own axis. As the mounting plate 13 rotates, it drives the limiting plate 7 to rotate, so that the limiting plate 7 first contacts the rectangular plate 32. The mounting plate 13 continues to rotate, so that the limiting plate 7 squeezes the rectangular plate 32, and the rectangular plate 32 drives the cutter 33 to squeeze the tablets, which has a better splitting effect on the tablets. Finally, the rotation of the ball 23 has a grinding effect on the tablets. Finally, the mounting plate 13 is rotated in the opposite direction, so that the ball 23 slides out of the placement plate 15, and the powder in the groove of the placement plate 15 can be taken out.

[0048] In some embodiments, the dividing component 3 further includes a positioning rod 34, which is fixedly connected to the placement plate 15 and passes through the rectangular plate 32. The positioning rod 34 limits the rectangular plate 32 so that it can only slide longitudinally, which facilitates the limiting plate 7 to squeeze the rectangular plate 32.

[0049] In some embodiments, the groove 31 and the cutter 33 are cross-shaped, which provides a better cutting effect for the tablets.

[0050] In some embodiments, a disassembly assembly 4 is provided on the base 11; the disassembly assembly 4 includes: a fixed base 41, fixedly connected to the base 11; a fixed plate 42, fixedly connected to the placement plate 15, and the fixed plate 42 is inserted into the fixed base 41; a round-headed rod 43, slidably connected to the fixed base 41, and one end of the round-headed rod 43 is inserted into the fixed plate 42; and a damping spring 44, sleeved on the round-headed rod 43, and the fixed plate 42 is connected to the fixed base 41 through the round-headed rod 43.

[0051] In use, pull the round-headed rod 43 outward so that one end slides out of the fixed plate 42, and at the same time pull the damping spring 44, then remove the placement plate 15 from the base 11 to facilitate cleaning the powder on the placement plate 15. Conversely, pull the rod outward to install the placement plate 15.

[0052] In some embodiments, the disassembly assembly 4 is provided in multiple sets, and the multiple sets of disassembly assembly 4 can be used simultaneously or individually.

[0053] In some embodiments, a sliding component 5 is provided on the base 11; the sliding component 5 includes: a limiting groove 51, which is formed on the fixed seat 41; a mounting seat 52, which is fixedly connected to the placement plate 15; and a plate body 53, which is slidably connected to the mounting seat 52, and one end of the plate body 53 is close to the round head rod 43.

[0054] In use, by pushing plate 53, the plate 53 slides within the mounting base 52, while simultaneously pushing multiple round-headed rods 43 outward, facilitating the disassembly of the placement plate 15.

[0055] In some embodiments, a rotating assembly 6 is provided on the base 11; the rotating assembly 6 includes: a slide groove 61, formed on the base 11; a slider 62, slidably connected to the slide groove 61; a spring 63, disposed on the slider 62, and the slider 62 is connected to the base 11 through the spring 63; a connecting seat 64, disposed on the upright plate 12; and a second plate 65, rotatably connected to the connecting seat 64, with both ends of the second plate 65 respectively abutting against the mounting plate 13 and the slider 62.

[0056] In use, rotating the mounting plate 13 clockwise causes the ball 23 to grind the tablets. Conversely, rotating the mounting plate 13 counterclockwise causes it to contact the second plate 65 and push the second plate 65 to rotate. As the second plate 65 rotates on the connecting seat 64, one end of the second plate 65 pushes the slider 62, which slides in the groove 61 and pulls the spring 63. Then, the slider 62 pushes the first plate 53, which in turn pushes multiple round-headed rods 43. This clockwise rotation of the mounting plate 13 causes the limiting plate 7 to press the rectangular plate 32, which in turn drives the cutter 33 to press the tablets, thus dividing them. Finally, the rotation of the ball 23 grinds the tablets. Rotating the mounting plate 13 counterclockwise allows the placement plate 15 to be disassembled for easy removal of the ground powder.

[0057] In some embodiments, the rotating assembly 6 further includes a limiting rod 66, which is fixedly connected to the slide groove 61 and passes through the slider 62, restricting the slider 62 to slide only laterally.

[0058] In some embodiments, the steering mechanism 21 includes: a housing 211 fixedly connected to the mounting plate 13, a first rod 22 passing through the mounting plate 13 and the first rod 22; a first bevel gear 212 fixedly connected to the first rod 22; a third rod 213 rotatably connected to the housing 211; and a second bevel gear 214 fixedly connected to the third rod 213 and meshing with the first bevel gear 212.

[0059] When in use, rotating the mounting plate 13 drives the shaft 14 and rod 213 to rotate through the transmission mechanism 25. While the rod 213 rotates, the meshing of bevel gear 212 and bevel gear 214 causes bevel gear 212 to drive rod 22 to rotate, thereby driving the ball 23 to rotate. When the ball 23 comes into contact with the tablet, it grinds the tablet.

[0060] In some embodiments, the transmission mechanism 25 includes: a first gear 251, fixedly connected to one end of the third rod 213; a sprocket 252, fixedly connected to the output end of the motor 24 and rotatably connected to the upright plate 12; a chain 253, through which the two sprockets 252 are connected; and a second gear 254, fixedly connected to the motor 24, and meshing with the first gear 251.

[0061] When in use, when the motor 24 is turned on, it drives the sprocket 252 and gear 254 to rotate through its output end. At the same time, the sprocket 252 rotates and is connected to another sprocket 252 through the chain 253, causing the mounting plate 13 to rotate. Through the rotation of gear 254, gear 1 drives rod 213 to rotate through gear 251, thereby driving rod 22 to rotate. Rod 22 drives ball 23 to rotate, so that when ball 23 comes into contact with the tablet, it grinds the tablet.

[0062] Specifically, sprocket 252 is rotatably connected to the upright plate 12 via a U-shaped frame, and is parallel to the orientation of another sprocket 252.
