A medicine storage box is slidably connected to the inner wall of one side of the shell. A dispensing device is provided on the top of the shell, and a crushing component is provided at the bottom of the dispensing device. A transmission mechanism is provided between the base and the crushing component. In this invention, the pills are squeezed together as they pass through the guide plate and slide to the top of the pills at the bottom. When the pills are at the top, they fall to the middle of the inclined turntable because there is no obstruction on one side. When the pills fall from the dispensing port onto the telescopic rotating plate, they push the telescopic rotating plate to rotate, transporting the pills to the pressure plate. Then, the telescopic rotating plate pushes the guide plate to rotate clockwise, so that the pills on the telescopic rotating plate fall onto the guide plate and fall into the medicine storage box along the inclined direction of the guide plate. This achieves the storage of excess pills and controls the amount of pills dispensed according to the different dosages of different patients, preventing accidental over-dispensing by human hands.

Description

Technical Field

[0001] This invention belongs to the field of emergency medicine technology, specifically a tablet crushing device suitable for emergency medicine. Background Technology

[0002] The emergency room refers to the emergency department of a hospital, meaning treatment in emergency situations, divided into emergency care and resuscitation. Its existence ensures that we can receive professional and scientific treatment as quickly as possible in the event of sudden illness or accidental injury. Many patients in the emergency room require long-term medication, and most existing medications are administered via sprays or oral medications. Some patients also suffer from other illnesses, making it difficult to swallow conventional pills or large tablets, thus requiring the use of tablet crushers.

[0003] In the use of existing tablet crushing devices, medical staff usually place the tablets into the device by hand or pour them directly from the pillbox. Direct contact between the tablets and hands may leave bacterial residues on the tablets, and too much may be poured out accidentally. Furthermore, the dosage used varies from patient to patient.

[0004] In summary, the present invention provides a tablet crushing device suitable for emergency treatment to solve the above-mentioned problems. Summary of the Invention

[0005] This invention provides a tablet crushing device suitable for emergency treatment, overcoming the shortcomings of existing technologies.

[0006] The technical solution of this invention is as follows:

[0007] A pill crushing device suitable for emergency use includes: a housing, a base, and a scraping mechanism. The base is installed inside the housing, the scraping mechanism is located on the top of the base, a medicine storage box is slidably connected to one inner wall of the housing, a dispensing device is provided on the top of the housing, a crushing component is provided at the bottom of the dispensing device, the crushing component is located on one side of the base inside the housing, and a transmission mechanism is provided between the base and the crushing component.

[0008] The dispensing device includes a second outer shell, a partition, and a motor. The second outer shell is fixedly connected to the top of the first outer shell. The partition is fixedly connected to the inside of the second outer shell. The motor is fixedly connected to the inside of the partition. An inclined turntable is fixedly connected to the output end of the motor. A third outer shell is slidably connected to the periphery of the inclined turntable. The bottom of the third outer shell is fixedly connected to the top of the partition. A guide plate is provided inside the third outer shell. The bottom of the guide plate is slidably connected to the top of the inclined turntable. A telescopic rotating plate is provided on one side of the partition. The telescopic rotating plate is rotatably connected to the inner wall of the first outer shell. A second guide plate is installed at the bottom of the telescopic rotating plate. The second guide plate is also rotatably connected to the inner wall of the first outer shell.

[0009] The guide plate 1 is inclined downward along its length, so that the end away from the outer shell 2 is lower than the end close to the outer shell 2. If the medicine particles are piled up together, they will squeeze each other during the process of passing through the guide plate 1. The inclined turntable is inclined towards the telescopic turntable.

[0010] The telescopic rotating plate has a first position and a second position: when in the first position, the telescopic rotating plate receives a tablet that slides off the guide plate and guides the tablet to the crushing assembly;

[0011] When in the second position, the telescopic rotating plate blocks the path of the tablet to the crushing assembly and guides the tablet to the second guide plate, through which it slides into the medicine storage box.

[0012] Furthermore, the compaction assembly includes an electric telescopic rod and a pressure plate. The bottom of the electric telescopic rod is fixedly connected to the bottom of the first outer casing, the pressure plate is fixedly connected to the top of the electric telescopic rod, the bottom of the second outer casing is fixedly connected to a guard plate, and the pressure plate is slidably connected inside the guard plate. The bottom of the partition is fixedly connected to a protruding plate.

[0013] Furthermore, the scraping mechanism includes a gear one, a motor fixedly connected to the bottom of the gear one, the bottom of the motor fixedly connected to the bottom of the base, a gear two slidably connected to one side of the gear one, a turntable provided on one side of the gear two, two cylinders symmetrically fixedly connected to both the gear one and the gear two, and three square slots opened on the turntable.

[0014] Furthermore, one end of gear two that extends into the base is fixedly connected to bevel gear one, one side of bevel gear one is slidably connected to bevel gear two, and the end of bevel gear two that is away from bevel gear one is fixedly connected to rotating rod one.

[0015] Furthermore, a first connecting rod is rotatably connected to the turntable. A second connecting rod is rotatably connected to the end of the first connecting rod away from the turntable. A fixed plate is rotatably connected to the end of the second connecting rod away from the first connecting rod. Both ends of the fixed plate are rotatably connected to a third connecting rod. Push plates are rotatably connected to the ends of the two third connecting rods away from the fixed plates. A limit rod is slidably connected to the third connecting rod near the push plate at one-third of its length. The limit rod is fixedly connected to the bottom plate of the outer casing.

[0016] Furthermore, the transmission mechanism includes a belt, a rotating rod 2, and a conveyor belt. The end of the rotating rod 1 away from the bevel gear 2 is slidably connected to the belt. The end of the belt away from the rotating rod 1 is sleeved on the rotating rod 2. One end of the rotating rod 2 is rotatably connected to the base. The conveyor belt is sleeved on the other end of the rotating rod 2. A rotating rod 3 is provided at the end of the conveyor belt away from the rotating rod 2. A push box is fixedly connected to the conveyor belt. A fixing rod is fixedly connected to the side wall of the outer casing 1 above the conveyor belt. A placement box is slidably connected to the fixing rod.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this invention, the pills slide to the top of the bottom pills as they are squeezed together while passing through the guide plate. When the pills are at the top, they fall to the middle of the inclined turntable because one side is not blocked. The partition plate has a medicine outlet near the telescopic turntable. When the pills fall from the medicine outlet onto the telescopic turntable, the telescopic turntable rotates counterclockwise, transporting the pills to the pressure plate. Then, the telescopic turntable pushes the guide plate to rotate clockwise, so that one end of the guide plate is blocked between the telescopic turntable and the pressure plate. This causes the pills on the telescopic turntable to fall onto the guide plate and into the medicine storage box along the inclined direction of the guide plate. This achieves the storage of excess pills and controls the dosage of pills according to different patients' medication needs, preventing accidental over-dispensing.

[0019] 2. In this invention, the medicine granules on the pressure plate are squeezed and crushed into powder. Then, the electric telescopic rod is turned off, and the pressure plate and guard plate move away from the convex plate, causing the medicine powder to move along with it. The guard plate surrounds the pressure plate to prevent the medicine powder from scattering during the movement. Then, the drive gear one rotates, which drives gear two to rotate. Gear two rotates, which in turn drives bevel gear one to rotate, and then drives bevel gear two to rotate. Rotating rod one rotates along with it, causing the belt to slide on rotating rod one and rotating rod two, thereby causing the conveyor belt to rotate. Each push box will jam a placement box when it passes the bottom of the placement box, causing the placement box to fall into the push box. During the movement of the push box, the placement box is placed on one side of the pressure plate, making it easier for the powder from the pressure plate to be scraped into the placement box.

[0020] 3. In this invention, the cylinder on gear one engages with the square groove on the turntable during rotation, causing the turntable to rotate. This rotation of connecting rod one causes connecting rod two to rotate, pulling the fixed plate towards the turntable. Connecting rod three follows the fixed plate and pulls the push plate to slide on the pressure plate, pushing the powder on the pressure plate into the placement box. Both sides of the push plate are equipped with fixing blocks that conform to the shape of the pressure plate to prevent the powder from scattering during the pushing process. Pouring the powder into the placement box makes it easy for medical staff to retrieve the powder, reducing the time medical staff spend loading the medicine. Attached Figure Description

[0034] The guide plate 36 is inclined downward along its length, so that the end away from the outer shell 31 is lower than the end close to the outer shell 31. If the pills are piled up together, they will squeeze each other during the process of passing through the guide plate 36, causing the pills that are pushed together to separate. The inclined turntable 34 is inclined towards the telescopic turntable 37.

One end of the rotating rod 62 is rotatably connected to the base 2. The conveyor belt 63 is sleeved on the other end of the rotating rod 62. A rotating rod 64 is provided at the end of the conveyor belt 63 away from the rotating rod 62. A push box 65 is fixedly connected to the conveyor belt 63. A fixing rod 66 is fixedly connected to the side wall of the outer casing 1 above the conveyor belt 63. A placement box 67 is slidably connected to the fixing rod 66.

[0042] Specific working principle:

[0043] First, such as Figure 1-3 and Figure 6As shown, medical staff insert the medication into the middle position of guide plate 36, and after setting the rotation angle according to the patient's dosage, the telescopic rotating plate 37 opens. Then, the motor 33 is started, driving the inclined rotating plate 34 to rotate. Due to the inclined rotating plate 34, the medication moves upward along the trajectory of guide plate 36 on the inclined rotating plate 34. Because the end of guide plate 36 is relatively short, and the other end of guide plate 36 gradually approaches the outer shell 31, the distance between them becomes smaller and smaller. If the medication accumulates together, it will squeeze against each other as it passes through guide plate 36. Since the pills are mostly round or oval, they slide to the top of the bottom pills when squeezed against each other. When the pills are at the top, they will fall onto the inclined rotating plate because one side is not protected. In the middle of 34, a medicine outlet is provided on the partition 32 near the telescopic rotating plate 37. When the medicine granules fall from the medicine outlet onto the telescopic rotating plate 37, the telescopic rotating plate 37 will rotate counterclockwise to transport the medicine granules to the pressure plate 42. If the patient needs two medicines, the telescopic rotating plate 37 will open after rotating about 60°, contacting the guide plate 38 and pushing the guide plate 38 to rotate clockwise. This causes one end of the guide plate 38 to block between the telescopic rotating plate 37 and the pressure plate 42, so that the medicine granules on the telescopic rotating plate 37 fall onto the guide plate 38 and fall into the medicine storage box 11 along the inclined direction of the guide plate 38. This achieves the storage of excess medicine granules and controls the amount of medicine granules dispensed according to the different dosages of different patients, preventing accidental dispensing of too many granules.

[0044] Then, as Figure 4-5 and Figure 7-8As shown, the electric telescopic rod 41 is activated, pushing the pressure plate 42 and the guard plate 43 towards the convex plate 44, causing the medicine granules on the pressure plate 42 to be squeezed and crushed into powder. Then, the electric telescopic rod 41 is deactivated, and the pressure plate 42 and the guard plate 43 move away from the convex plate 44, causing the medicine powder to move along with them. The guard plate 43 surrounds the pressure plate 42 to prevent the medicine powder from scattering during the movement. Next, the micro motor 33 is activated, driving gear 1 51 to rotate, which in turn drives gear 2 52 to rotate. Gear 2 52 rotates, which in turn drives bevel gear 1 521 to rotate, and then drives bevel gear 2 522 to rotate. Rotating rod 1 523 rotates along with the belt 61, causing belt 61 to slide on rotating rod 1 523 and rotating rotating rod 2 62. This causes the conveyor belt 63 to rotate, and the push boxes 65 move upwards. Each push box 65 will jam a placement box 67 when it passes the bottom of the placement box 67. 67, causing the placement box 67 to fall into the push box 65. During the movement of the push box 65, the placement box 67 is placed on one side of the pressure plate 42, making it easier for the powder on the pressure plate 42 to be scraped into the placement box 67. At the same time, the cylinder on the gear 1 51 is engaged in the square groove on the turntable 53 during rotation, driving the turntable 53 to rotate. This causes the connecting rod 1 531 to rotate, driving the connecting rod 2 532 to rotate, pulling the fixing plate 533 to move towards the turntable 53. The connecting rod 3 534 follows the movement of the fixing plate 533 and pulls the push plate 535 to slide on the pressure plate 42, pushing the powder on the pressure plate 42 into the placement box 67. Both sides of the push plate 535 are provided with fixing blocks that fit the shape of the pressure plate 42 to prevent the powder from scattering during the pushing process. Pouring the powder into the placement box 67 makes it easier for medical staff to take out the powder and reduces the time for medical staff to load the medicine.
