Description

Technical Field

[0001] This invention relates to the field of nursing-related technology, specifically to a medication crushing device for nursing use. Background Technology

[0002] Nursing tablet crushers are mainly used in medical institutions and home care to provide patients with a convenient and safe way to take medication. Their main function is to crush tablets into powder so that patients can swallow or absorb them orally.

[0003] Different patients require different dosages of medication. Currently, most medication crushing devices on the market grind tablets completely into powder. After removing the entire device, the remaining powder needs to be cleaned up. If some patients only need half the dose of a tablet or a dose of one and a half tablets, the remaining powder will be exposed to the air and easily become damp or mix with other dust, causing contamination or deterioration of the powder. In addition, most of the existing fully functional medication crushing devices are large and not easy to carry. Summary of the Invention

[0004] This invention provides a medication crushing device for nursing care, which cuts tablets with a cutter and stores them separately. The operation is simple and easy to use, and the device is compact and portable, thus solving the problems existing in the prior art.

[0005] The technical solution of this invention is as follows:

[0006] A medication crushing device for nursing care includes an upper shell and a transparent cover. The top of the upper shell is threadedly connected to the transparent cover. A partition is fixedly connected to the bottom of the upper shell. The partition has a first discharge port and a second discharge port. A fixing component is disposed inside the upper shell. A lower shell is fixedly connected to the bottom of the partition. The lower shell has two square holes. A cleaning component is disposed inside the lower shell. A pushing component is disposed on one side of the cleaning component.

[0007] The transparent cover has a V-shaped groove, and an elastic plate is fixedly connected inside the V-shaped groove to prevent external contaminants from entering the upper housing. A cutter is slidably connected to the middle of the V-shaped groove, and a pressure rod is slidably connected to one end of the V-shaped groove.

[0008] The fixing assembly includes a telescopic ring and a pull rod. The telescopic ring is disposed on the outside of the upper housing. One end of the telescopic ring is fixedly connected to the pull rod. The other end of the pull rod horizontally penetrates the upper housing and is slidably connected to the upper housing. A push plate is fixedly connected to the end of the pull rod that horizontally penetrates the upper housing.

[0009] The cleaning assembly includes a cylinder, a fixed rod, and a connecting rod. The cylinder passes through the partition and is located on one side of the second discharge port. One end of the fixed rod is fixedly connected to the pressure rod, and the other end is slidably connected inside the cylinder. The connecting rod is located inside the cylinder, and its top end is rotatably connected to the end of the fixed rod inside the cylinder. The bottom end of the connecting rod extends out of the cylinder. A shaped turntable is provided at the bottom of the cylinder. The bottom end of the connecting rod extends out of the cylinder and is rotatably connected to the shaped turntable. A rotating shaft is rotatably connected to one side of the shaped turntable. The rotating shaft is fixedly connected to the inner wall of the lower housing. A telescopic rod is fixedly connected to one side of the bottom end of the connecting rod. A push plate is fixedly connected to the end of the telescopic rod away from the connecting rod. A pressure plate is provided on one side of the push plate. The pressure plate is located at the bottom of the second discharge port, and the bottom of the pressure plate is fixedly connected to the telescopic rod.

[0010] The pushing component includes a rotating plate, a square groove, and a rack. The rotating plate is rotatably connected to the bottom of the partition and located on the side of the connecting rod away from the telescopic rod. The square groove is formed on the rotating plate, and the rack passes through the square groove. One end of the rack is provided with a storage box, which is located at the bottom of the discharge port. A gear is slidably connected to the bottom of the rack, and a rack is slidably connected to the bottom of the gear. One end of the rack is fixedly connected to the rotating plate, and the other end of the rack is provided with a storage box, which is located on one side of the pressure plate.

[0011] Furthermore, a spring is provided between the outer tube and the inner tube of the telescopic rod one, the push plate two is arc-shaped and part of its inner wall contacts the outer wall of the pressure plate, the outer diameter of the pressure plate is larger than the outer diameter of the pressure rod, so that the push plate two can extend onto the pressure plate when the pressure plate moves down, and a spring two is fixedly connected between the outer tube and the inner tube of the telescopic rod two.

[0012] Furthermore, spring 3 is fixedly connected to the bottom of both storage box 1 and storage box 2. A bottom cover is fixedly connected to the bottom of spring 3. A sleeve is rotatably connected to the top of the bottom cover. A push plate is fixedly connected to the top of the sleeve. One end of the push plate extends out of the square hole.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This invention uses a cutter to drop two halves of the tablet into outlet one and outlet two respectively, facilitating different processing methods for the two halves. The pressure rod pushes the inner tube of the pressure plate and telescopic rod two downwards, compressing spring two. After the pressure plate moves below the push plate two, spring one pops outwards and pushes telescopic rod one outwards, pushing push plate two onto the pressure plate. Since the outer diameter of the pressure rod is smaller than the outer diameter of the pressure plate, push plate two is located outside the pressure rod. After the nurse pushes the pressure plate to the bottom, the continuous pressure crushes the tablet.

[0015] 2. In this invention, the powder on the pressure plate is pushed into the storage box 2 by the pusher plate 2, and the surface of the pressure plate is cleaned. At the same time, the spring 2 is kept in a compressed state. Then, when one end of the irregular turntable rotates to the direction close to the turntable, it drives the telescopic rod 1 away from the pressure plate. At this time, the spring 2 loses pressure and bounces upward, extending the telescopic rod 2 and returning the pressure plate to its position for easy use next time.

[0016] 3. This invention uses a shaped turntable to drive rack two to move and rotate gears, while simultaneously driving rack one to move in the opposite direction and pushing storage box one and storage box two towards the push plate. This saves nursing staff time in pouring out and cleaning up powder. The device can be selected by the patient to chop or pulverize according to their needs, and can store different forms of drugs separately. The operation process is simple and easy to use, and the whole device is small and easy to carry. Attached Figure Description

[0025] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0026] like Figure 1-6 As shown, the present invention provides a nursing medicine crushing device, including an upper shell 1 and a transparent cover 2. The top of the upper shell 1 is threadedly connected to the transparent cover 2. A partition 11 is fixedly connected to the bottom of the upper shell 1. The partition 11 has a discharge port 12 and a discharge port 13. A fixing component 3 is provided inside the upper shell 1. A lower shell 4 is fixedly connected to the bottom of the partition 11. The lower shell 4 has two square holes 41. A cleaning component 5 is provided inside the lower shell 4. A pushing component 6 is provided on one side of the cleaning component 5.

[0027] The transparent cover 2 has a V-shaped groove 21, and an elastic plate 22 is fixedly connected inside the V-shaped groove 21 to prevent external contaminants from entering the upper shell 1 and contaminating the tablets. A cutter 23 is slidably connected to the middle of the V-shaped groove 21, and a pressure rod 24 is slidably connected to one end of the V-shaped groove 21.

[0028] The fixing component 3 includes a telescopic ring 31 and a pull rod 32. The telescopic ring 31 is disposed on the outside of the upper housing 1. The telescopic ring 31 is fixedly connected to one end of the pull rod 32. The other end of the pull rod 32 horizontally penetrates the upper housing 1 and is slidably connected to the upper housing 1. A push plate 33 is fixedly connected to one end of the pull rod 32 that horizontally penetrates the upper housing 1.

[0029] The cleaning assembly 5 includes a cylinder 51, a fixed rod 52, and a connecting rod 53. The cylinder 51 passes through the partition 11 and is located on one side of the discharge port 13. One end of the fixed rod 52 is fixedly connected to the pressure rod 24, and the other end is slidably connected inside the cylinder 51. The connecting rod 53 is located inside the cylinder 51, and its top end is rotatably connected to the end of the fixed rod 52 located inside the cylinder 51. The bottom end of the connecting rod 53 extends out of the cylinder 51. A shaped turntable 54 is provided at the bottom of the cylinder 51. The bottom end of the connecting rod 53 extends out of the cylinder 51 and is rotatably connected to the irregular turntable 54. A rotating shaft is rotatably connected to one side of the irregular turntable 54. The rotating shaft is fixedly connected to the inner wall of the lower housing 4. A telescopic rod 55 is fixedly connected to one side of the bottom end of the connecting rod 53. A push plate 56 is fixedly connected to the end of the telescopic rod 55 away from the connecting rod 53. A pressure plate 57 is provided on one side of the push plate 56. The pressure plate 57 is located at the bottom of the discharge port 13. A telescopic rod 58 is fixedly connected to the bottom of the pressure plate 57.

[0030] The pushing component 6 includes a rotating plate 61, a square groove 62, and a rack 63. The rotating plate 61 is rotatably connected to the bottom of the partition plate 11 and is located on the side of the connecting rod 53 away from the telescopic rod 55. The square groove 62 is formed on the rotating plate 61, and the rack 63 passes through the square groove 62. One end of the rack 63 is provided with a storage box 64, which is located at the bottom of the discharge port 12. The bottom of the rack 63 is slidably connected to a gear 65, and the bottom of the gear 65 is slidably connected to a rack 66. One end of the rack 66 is fixedly connected to the rotating plate 61, and the other end of the rack 66 is provided with a storage box 67, which is located on one side of the pressure plate 57.

[0031] As a technical solution of the present invention, a spring 551 is provided between the outer tube and the inner tube of the telescopic rod 55. The push plate 56 is arc-shaped and has part of its inner wall in contact with the outer wall of the pressure plate 57. The outer diameter of the pressure plate 57 is larger than the outer diameter of the pressure rod 24, so that the push plate 56 can extend onto the pressure plate 57 when the pressure plate 57 moves down. When the pressure rod 24 leaves the pressure plate 57, the push plate 56 restricts the pressure plate 57 from moving upward with the pressure rod 24, thereby facilitating the push plate 56 to clean the powder on the surface of the pressure plate 57. A spring 581 is fixedly connected between the outer tube and the inner tube of the telescopic rod 58.

[0032] As a technical solution of the present invention, the bottom of the storage box 64 and the storage box 67 are both fixedly connected to the spring 671, the bottom of the spring 671 is fixedly connected to the bottom cover 672, the top of the bottom cover 672 is rotatably connected to the sleeve 673, the top of the sleeve 673 is fixedly connected to the push plate 674, and one end of the push plate 674 extends out of the square hole 41.

[0033] Working principle:

[0034] First, such as Figure 1-2 As shown, when a patient needs to take half a pill, the caregiver picks up the transparent cover 2, places the pill on the partition 11, then closes the transparent cover 2, and pushes a lever 32, causing the telescopic ring 31 to retract inward. This, in turn, causes the other two levers 32 to simultaneously push the push plate 33 towards the center, placing the pill in the center of the partition 11 and fixing it in place to prevent the pill from shifting during cutting and causing uneven cutting. When the caregiver sees the pill in the center through the transparent cover 2, they press the cutter 23 downward and cut the pill in the middle. Then, the caregiver pulls the lever 32 outward. Pulling causes the pusher plates 33 to separate and lose their restraint on the tablets. At this time, the cutter 23 is positioned between the tablets. The nurse pushes the cutter 23 to slide towards one end of the V-groove 21. Since the elastic plate 22 has an opening in the middle, the two elastic plates 22 are connected when the cutter 23 is not slid in, preventing external contaminants from entering the upper housing 1 and contaminating the tablets. When the cutter 23 slides in, the two elastic plates 22 are separated by force. At this time, the cutter 23 pushes half of the tablets into the discharge port 12 for storage. Then, the cutter 23 pushes the other half of the tablets towards the discharge port 23 for separate processing of the two halves of the tablets.

[0035] Then, as Figure 3-4 As shown, when the tablet falls from the discharge port 213 onto the pressure plate 57, the nurse presses the pressure rod 24, pushing the inner tube of the pressure plate 57 and the telescopic rod 258 downwards, and compressing the spring 2581. After the pressure plate 57 moves below the push plate 256, the spring 1551 pops outwards and pushes the telescopic rod 155 outwards, pushing the push plate 256 onto the pressure plate 57. Since the outer diameter of the pressure rod 24 is smaller than the outer diameter of the pressure plate 57, the push plate 256 is located outside the pressure rod 24. After the nurse pushes the pressure plate 57 to the bottom, the continuous pressure crushes the tablet.

[0036] like Figure 2-5As shown, it should be noted that: when the pressure rod 24 presses down, it drives the fixed rod 52 to move downward. Since the rotating shaft is fixedly connected to the lower housing 4, the connecting rod 53 drives the irregularly shaped turntable 54 to rotate towards the pressure plate 57, and pushes the telescopic rod 55 to move towards the pressure plate 57. However, at this time, the pressure rod 24 is on the pressure plate 57, so the push plate 56 cannot continue to move forward and can only continuously compress the spring 551. After the tablet is crushed, the nurse pulls the pressure rod 24 upward, and the pressure rod 24 separates from the pressure plate 57. At this time, the pressure rod 24 drives the fixed rod 52 to move upward, so that the irregularly shaped turntable 54 begins to rotate in another direction. Pulling the telescopic rod 55 moves it in the same direction, but because the compressed spring 551 is no longer restricted by the pressure rod 24, it will still pop out towards the pressure plate 57 and extend the telescopic rod 55, so that the push plate 56 pushes the powder on the pressure plate 57 into the storage box 67, cleaning the surface of the pressure plate 57. At the same time, the spring 581 is kept in a compressed state. Then, when one end of the irregular turntable 54 rotates to the direction close to the turntable 61, it drives the telescopic rod 55 away from the pressure plate 57. At this time, the spring 581 loses pressure and bounces upward, extending the telescopic rod 58 and returning the pressure plate 57 to its position for the next use.

[0037] At the same time, such as Figure 3-6 As shown, when one end of the irregularly shaped turntable 54 rotates to the direction close to the rotating plate 61, it pushes one end of the rotating plate 61 to rotate. The other end of the rotating plate 61 pushes the rack 66 to move, and pushes the storage box 67 towards the square hole 41, so that the storage box 67 carries the powder out of the lower shell 4. At this time, the nurse can directly pour water into the storage box 67 to dissolve the powder, saving the nurse the time of pouring out and cleaning the powder. When the rack 66 moves, it drives the gear 65 to rotate, and at the same time drives the rack 63 to move in the opposite direction, pushing the storage box 64 out of the lower shell 4. The nurse can directly put the medicine into the storage box 64. The tablets are stored in storage box 64 to reduce contact with other objects and prevent contamination. After the upper storage boxes 64 and 67 leave the sleeve 673, the spring 671 pushes the remaining storage boxes 64 and 67 upwards, so that they are located at the bottom of the discharge ports 12 and 13 respectively, facilitating secondary storage of the tablets. This device allows patients to choose between chopping or pulverizing according to their needs, and stores different forms of drugs separately. The operation is simple and easy to use, and the device is compact and portable.
