Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an adjustable single-dose tablet cutter. Background Technology

[0002] In the field of clinical pharmacy, for special populations such as children, pregnant women, or those with certain organ dysfunction, the dosage of therapeutic drugs should be individualized according to individual circumstances. Therefore, in clinical medication, doctors often order 3 / 4, 1 / 2, or even 1 / 4 of a certain tablet to be taken orally. In this case, the dispensing pharmacist needs to separate and cut the tablet to reduce the dosage and achieve the goal of precise individualized drug administration.

[0003] In traditional methods, it is common for pharmacists to break or cut tablets by hand or with scissors. Many pharmaceutical manufacturers design a groove in the center of the tablet to make it easier for patients to break it themselves to obtain a single dose of 1 / 2 tablet. However, it is difficult to obtain a dose of 1 / 4 or less in this way. In addition, the tablets are usually small in size, and it is not only difficult to accurately control the dosage when separating the tablets by hand, but the separation is also more difficult. Furthermore, traditional methods greatly increase the contact between the medicine and the hands, increasing the chance of contamination. Utility Model Content

[0052] Detailed Implementation

[0053] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0054] This utility model discloses an adjustable single-dose tablet cutter. With a cross-shaped detachable blade and a liftable baffle design, it can cut a whole tablet into two, four, or half a tablet into two parts, for a total of three cutting methods. Compared with the manual breaking of medicine in the prior art, it reduces the contact between the medicine and the hand while ensuring the uniformity of the cut.

[0055] According to the adjustable single-dose tablet cutter provided by this utility model, such as Figure 1 As shown, it includes, from top to bottom, a top cover assembly 2, a limiting container 3, an internal toothed ring assembly 4, and a tablet tray assembly 5;

[0056] like Figure 2 As shown, the top cover assembly 2 is connected to the limiting container 3 for opening and closing, and a blade assembly 1 corresponding to the tablet cutting seat 29 is installed at the center of the inner top of the top cover assembly 2. The blade assembly 1 includes a first blade and a second blade. The first blade is fixedly installed on the inner top of the top cover assembly 2, and the second blade is detachably installed in the middle of the first blade to form a cross structure. In a preferred embodiment, the top cover assembly 2 includes a top cover body, a blade fixing clip 8, a blade mounting seat 9, and a hinge 10. The blade mounting seat 9 is installed on the top of the top cover body. One side of the top cover body is connected to the limiting container 3 for opening and closing through the hinge 10. The blade fixing clip 8 is fixedly installed on the bottom of the top cover body to fix the second blade. When the second blade is removed, it is folded to the top of the top cover body through the hinge on one side and fixed by the blade fixing clip 8. At this time, the lower edge of the second blade is higher than the lower surface of the blade mounting seat 9.

[0057] like Figure 6 As shown, the tablet tray assembly 5 includes a tablet tray body, a tablet cutting seat 29 mounted on the tablet tray body, and a tablet clamping structure disposed around the tablet cutting seat 29. The portion of the tablet cutting seat 29 located in the tablet clamping structure forms a tablet clamping position 31 for placing tablets. The tablet tray assembly 5 is provided with a liftable baffle 30. The axis of the tablet clamping position 31 is located on the plane of the baffle 30. The baffle 30 is perpendicular to the first blade, and the center line of the baffle 30 is located on the plane of the first blade. In a preferred embodiment, a blade receiving groove 32 is provided in the middle of the baffle 30. The groove size of the blade receiving groove 32 needs to be slightly larger than the thickness of the first blade. In the third cutting state, when the top cover assembly 2 is closed, the first blade is located in the blade receiving groove 32.

[0058] By setting a first blade and a detachable second blade at the bottom of the top cover assembly 2, a straight or cross-shaped blade can be formed. With the liftable baffle 30 on the tablet tray assembly 5, three cutting methods can be achieved, as follows: First cutting state: The second blade is not installed on the first blade and is fixed to the top of the top cover assembly 2 by the blade fixing clip 8. The baffle 30 is lowered into the inside of the tablet tray assembly 5, and its upper edge is lower than the upper surface of the tablet cutting seat 29. At this time, the tablet cutter is used to cut the whole tablet in half with the straight first blade to form a half tablet.

[0059] Second cutting state: The second blade is mounted on the first blade. Specifically, the end of the second blade without the hinge is fitted with a buckle, which is fixed to the top of the blade mounting base 9, thereby fixing it in the groove in the middle of the first blade to form a cross structure. The baffle 30 is lowered into the inside of the tablet tray assembly 5, and its upper edge is lower than the upper surface of the tablet cutting base 29. At this time, the tablet cutter is used to cut the whole tablet into four parts through the cross-shaped blade assembly to form a quarter tablet.

[0060] Third cutting state: The second blade is not installed on the first blade and is fixed to the top of the top cover assembly 2 by the blade fixing clip 8. The baffle 30 extends out of the tablet cutting seat 29, and its upper edge is higher than the upper surface of the tablet cutting seat 29. It cooperates with the tablet clamping structure to form a semi-cylindrical tablet clamping position, thereby clamping half a tablet. At this time, the cutter is used to cut the half tablet in half with the straight first blade to form a quarter tablet.

[0061] like Figure 5 , 6 As shown, multiple tablet clamping structures are circumferentially mounted on the outer side of the tablet cutting seat 29. Each tablet clamping structure includes a gear 17, a slide rail 18, an adjusting slider 20, and an adjusting block 24. The gear 17 is rotatably mounted on the tablet tray body, the slide rail 18 is radially mounted on the tablet tray body, and the adjusting slider 20 is slidably mounted on the slide rail 18. The side of the adjusting slider 20 is provided with a rack 22 that meshes with the gear 17, and the inner end of the adjusting slider 20 is equipped with an adjusting block 24. The inner side of the adjusting block 24 is an arc-shaped curved surface clamping part 26, which is designed to be inclined from top to bottom outwards. A frustum-shaped tablet clamping position 31 is formed between the multiple arc-shaped curved surface clamping parts 26.

[0062] The internal gear ring assembly 4 is coaxially installed between the limiting container 3 and the tablet tray assembly 5. The internal gear ring assembly 4 includes an internal gear ring 15 and two upper and lower rotating adjustment annular grooves 16 disposed on the outside of the internal gear ring 15. The inner side of the internal gear ring 15 is used to mesh with the gear 17 to form a planetary gear structure. The upper and lower rotating adjustment annular grooves 16 engage with the first internal gear ring engaging part 14 and the second internal gear ring engaging part 27, thereby achieving both limiting and reversible rotation, thereby driving the internal gear ring 15 to rotate. This, in turn, drives the adjusting slider 20 and the adjusting block 24 to slide radially along the slide rail 18 through the gear 17. When it is necessary to clamp tablets, the gear 17 is rotated by rotating the adjusting ring. The gear 17 drives the adjusting slider 20 and the adjusting block 24 to open or close through the rack 22 on the side of the adjusting slider 20. The arc-shaped clamping part 26 on the inner side of the adjusting block 24 can clamp tablets of different sizes. Figure 7 The image shows the closed state of the tablet clamping structure, as shown. Figure 8 The image shows the tablet clamping structure in its open state.

[0063] In a preferred embodiment, the adjusting slider 20 is slidably mounted on the slide rail 18 via a slide rail groove 21 at its bottom; the adjusting block 24 is provided with second mounting holes 25 arranged radially, and the end of the adjusting slider 20 is provided with a first mounting hole 23 corresponding to the second mounting hole 25; the adjusting block 24 is fixedly mounted on the first mounting hole 23 of the adjusting slider 20 via the second mounting hole 25; the cross-section of the adjusting block 24 is fan-shaped, and the inner side of the adjusting block 24 gradually tilts towards the axis of the tablet clamping position 31 from bottom to top; when the tablet clamping structure is closed, a ring structure is formed between the multiple adjusting blocks 24, and the central part of the ring structure is the tablet clamping position 31 with a frustum-shaped cavity. The contact surfaces between the adjusting blocks are provided with a retractable material to prevent the tablet from sliding into the gap and getting stuck when the adjusting blocks are separated.

[0064] In a preferred embodiment, on the radial projection of the annular structure formed by the adjusting block 24, the inner surface of the adjusting block 24 has a structure that gradually concaves radially from top to bottom. When the tablet is clamped by the adjusting block 24, it can be pressed tightly by the structure that gradually concaves radially from top to bottom, thereby preventing the tablet from being ejected by force during the clamping process.

[0065] like Figure 3 As shown, the limiting container 3 includes a limiting container sidewall 11 and a limiting container bottom plate 12 whose upper surfaces gradually slope downward from the outer periphery to the center; the limiting container bottom plate 12 has a through hole 7 corresponding to the tablet clamping position 31 installed in the middle; the limiting container sidewall 11 is installed circumferentially on the outer edge of the limiting container bottom plate 12; when the top cover assembly 2 is closed, the limiting container sidewall 11 is located inside the top cover assembly 2; the bottom outer edge of the limiting container 3 is provided with a downwardly protruding first internal toothed ring engaging part 14; preferably, the bottom of the limiting container 3 is designed to gradually descend from the outer periphery to the center, which facilitates the tablet to slide to the center position by itself;

[0066] like Figure 5As shown, a second internal toothed ring engaging portion 27 protruding upwards is installed circumferentially along the top outer edge of the tablet tray body; the rotation adjustment annular groove 16 and the internal toothed ring 15 are sequentially provided from top to bottom with a first slot corresponding to the first internal toothed ring engaging portion 14, a connecting portion, and a second slot corresponding to the second internal toothed ring engaging portion 27; the limiting container 3 is connected to the first slot of the internal toothed ring assembly 4 through the first internal toothed ring engaging portion 14, and the tablet tray body is connected to the second slot of the internal toothed ring assembly 4 through the second internal toothed ring engaging portion 27. By engaging and limiting the first internal toothed ring engaging portion 14 with the first slot and the second internal toothed ring engaging portion 27 with the second slot, coaxiality can be ensured among the limiting container 3, the internal toothed ring assembly 4, and the tablet tray assembly 5.

[0067] like Figure 3 , 5 As shown, the tablet tray body is equipped with multiple positioning posts 19, and the bottom plate 12 of the limiting container is equipped with multiple positioning holes 13 corresponding to the positioning posts 19. Through the positioning posts 19 and positioning holes 13 arranged along the circumference, the relative fixation between the limiting container 3 and the tablet tray assembly 5 can be ensured, and the relative rotation between the limiting container 3 and the tablet tray assembly 5 can be ensured when the internal toothed ring assembly 4 rotates to adjust the tablet clamping structure.

[0068] like Figure 9 As shown, a tablet lifting mechanism is provided in the internal space of the tablet tray body. The tablet lifting mechanism is used to drive the tablet 30 to extend out of the tablet cutting seat 29 or descend into the tablet tray body. Specifically, the tablet lifting mechanism includes a knob 6, a transmission rod 28, a rotating wheel, and a baffle support column 34. One end of the knob 6 is movably disposed on the side of the tablet tray body, and the other end of the knob 6 is coaxially connected to the rotation shaft 38 of the rotating wheel through the transmission rod 28. A ratchet is installed on the side of the rotating wheel.

[0069] Projected along the axial direction, the wheel includes a recessed portion 40 and an outwardly protruding support portion 37. The recessed portion 40 and the support portion 37 are connected by a smooth curve. The top end of the baffle support column 34 is installed at the bottom of the baffle plate 30. When the bottom end of the baffle support column 34 abuts against the recessed portion 40, the baffle plate 30 is located inside the tablet tray body. When the bottom end of the baffle support column 34 abuts against the top of the support arm 37, the baffle plate 30 extends out of the tablet cutting seat 29.

[0070] In a preferred embodiment, a return spring 35 is sleeved on the outside of the baffle support column 34, a positioning ball 36 is installed at the lower end of the baffle support column 34, and a spring baffle 33 is installed at the top of the internal space of the tablet tray body; the upper and lower ends of the return spring 35 are respectively used to abut against the spring baffle 33 and the positioning ball 36; the rotating wheel includes a plurality of recesses 40 and a plurality of support portions 37 arranged sequentially along the circumference; the top of the support portion 37 is provided with an arc-shaped support groove 39 for abutting against the bottom of the positioning ball 36; when the bottom end of the baffle support column 34 abuts against the top of the support arm 37, the positioning ball 36 is engaged in the arc-shaped support groove 39.

[0071] When it is necessary to raise or lower the baffle 30, rotate the knob 6 located on the side. The knob 6 drives the rotating wheel to rotate in one direction via the transmission rod 28. The recessed part 40 on the outer side of the rotating wheel and the support part 37 will periodically abut against the baffle support column 34. When the positioning ball 36 at the bottom of the baffle support column 34 abuts against the arc-shaped support groove 39 at the top of the support part 37, the positioning ball 36 is limited by the edge of the arc-shaped support groove 39. The operator will feel a certain resistance in the knob 6. At this time, the baffle 30 has been raised or lowered. Once raised to the correct position, if it is necessary to lower the baffle 30, simply turn the knob 6 in the same direction of rotation. At this time, the positioning ball 36 will slide down the edge of the arc-shaped support groove 39 under the action of torque, and abut against the recessed part 40 under the action of the return spring 35. At this time, the positioning ball 36 is limited by the edge of the recessed part 40, and the operator will feel a certain resistance in the knob 6, indicating that the baffle 30 has been completely lowered into the body of the tablet tray. If it is necessary to raise the baffle 30, simply rotate the knob 6 further.
