Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically, it relates to a novel tablet drug divider. Background Technology

[0002] In daily medication use, some tablet medications need to be split according to dosage requirements, such as breaking whole tablets apart. In addition, some tablets are too large to swallow directly and need to be split into smaller sizes. Therefore, tablet splitters have become a common tool in homes, medical institutions and other settings to meet the needs of precise dosage control and convenient administration.

[0003] However, existing dividers have automatic retraction mechanisms to prevent the cutter from being exposed and causing accidental injury when not in use. This results in the cutter remaining inside the device for extended periods. After the medicine is divided, powder or fragments may remain on the cutter surface. If the cutter is not thoroughly cleaned, the remaining medicine may breed bacteria or cause cross-contamination when dividing different medicines in the future, affecting the hygiene and safety of medication use.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0008] In a preferred embodiment of this utility model, a sliding groove is provided in the pressing block, and the connecting rod, crossbar and threaded rod are all slidably installed in the sliding groove.

[0009] In a preferred embodiment of this utility model, the base is provided with a positioning groove, the two ends of the positioning groove are set with V-shaped structures, and an avoidance groove is provided on the base corresponding to the position of the cutter, the depth of the avoidance groove being greater than the maximum downward distance of the cutter.

[0010] In a preferred embodiment of this utility model, the base is provided with a limiting block, and the bottom of the dividing cover is provided with a limiting groove that matches the limiting block. The dividing cover and the base are positioned at the installation angle through the cooperation of the limiting block and the limiting groove.

[0011] In a preferred embodiment of this utility model, the locking nut is located outside the pressing block, and the threaded rod cooperates with the locking nut to make the clamping member and the pressing block relatively close or separate to achieve the extension and locking of the cutter.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0021] like Figures 1 to 3 As shown, a novel tablet splitter includes a base 1 and a splitting cover 2. A clamping member 3 and a pressing block 4 are slidably installed inside the splitting cover 2. A cutter 5 is installed at the bottom of the pressing block 4. A return spring 9 is provided between the clamping member 3 and the pressing block 4. A compression spring 8 is provided between the splitting cover 2 and the clamping member 3. Two connecting rods 10 are connected to the clamping member 3. A crossbar 12 is connected to the two connecting rods 10. A threaded rod 13 is connected to the crossbar 12. A locking nut 14 for locking the relative position of the pressing block 4 and the clamping member 3 is engaged on the threaded rod 13. In this setup, base 1 is used to place tablets, divider cover 2 is used to accommodate and install various internal components, clamping member 3 can slide inside divider cover 2 to squeeze and position tablets during placement, preventing tablets from sliding, pressing block 4 is used to drive cutter 5 to move up and down to achieve tablet division, cutter 5 is the execution component for dividing tablets, return spring 9 is used to reset pressing block 4 when no force is applied, causing cutter 5 to retract into divider cover 2, compression spring 8 is used to apply downward pressure to clamping member 3 to ensure the squeezing and positioning effect of tablets, two connecting rods 10, crossbar 12 and threaded rod 13 together form a connecting structure to connect clamping member 3 to locking nut 14, locking nut 14 can lock the relative position of pressing block 4 and clamping member 3 by meshing with threaded rod 13, realizing the extension and locking of cutter 5 for cleaning.

[0022] like Figures 1 to 3 As shown, in a specific embodiment, the clamping member 3 is provided with a first connecting ring 6 and a second connecting ring 7. The first connecting ring 6 is slidably installed inside the dividing cover 2 and is fitted with a compression spring 8. The two ends of the compression spring 8 are respectively connected to the dividing cover 2 and the clamping member 3. The second connecting ring 7 is slidably installed inside the pressing block 4 and is fitted with a return spring 9. The two ends of the return spring 9 are respectively connected to the bottom of the pressing block 4 and the clamping member 3. In this configuration, the first connecting ring 6 provides the installation position and guide for the compression spring 8, enabling the compression spring 8 to stably apply downward pressure to the clamping member 3, while allowing the clamping member 3 to slide smoothly inside the dividing cover 2. The second connecting ring 7 provides the installation position and guide for the return spring 9, ensuring that the return spring 9 can apply an upward return force to the pressing block 4 without affecting the up-and-down sliding of the pressing block 4.

[0023] like Figures 1 to 3As shown, the pressing block 4 is further provided with a sliding groove 11, in which the connecting rod 10, the crossbar 12, and the threaded rod 13 are all slidably installed. In this configuration, the sliding groove 11 provides a sliding track for the connecting rod 10, the crossbar 12, and the threaded rod 13, ensuring that when the locking nut 14 is rotated, the clamping member 3 and the pressing block 4 can stably approach or separate relative to each other, ensuring the smooth extension, locking, or reset of the cutter 5.

[0024] like Figures 1 to 3 As shown, the base 1 is further provided with a positioning groove 15, the two ends of which are V-shaped structures. A clearance groove 16 is provided on the base 1 corresponding to the position of the cutter 5, the depth of which is greater than the maximum downward distance of the cutter 5. In this configuration, the positioning groove 15 is used to place the tablets, and its V-shaped structures at both ends can accommodate tablets of different sizes, providing good positioning for the tablets and ensuring that the center line of the tablet is located in the center of the divider, thus guaranteeing the accuracy of the division. The clearance groove 16 provides sufficient downward space for the cutter 5 when dividing the tablets, preventing the cutter 5 from hitting the base 1 when it reaches the bottom, thus preventing damage to the cutter 5.

[0025] like Figures 1 to 3 As shown, the base 1 is further provided with a limiting block 17, and the bottom of the dividing cover 2 is provided with a limiting groove 18 that matches the limiting block 17. The dividing cover 2 and the base 1 are positioned at the installation angle through the cooperation of the limiting block 17 and the limiting groove 18. In this setting, the limiting block 17 and the limiting groove 18 cooperate with each other to accurately determine the installation angle between the dividing cover 2 and the base 1, ensuring that after the dividing cover 2 is installed on the base 1, the cutter 5 can accurately align with the tablet in the positioning groove 15 on the base 1, ensuring the normal operation of the dividing work.

[0026] like Figures 1 to 3 As shown, further, the locking nut 14 is located outside the pressing block 4. The threaded rod 13 cooperates with the locking nut 14 to make the clamping member 3 and the pressing block 4 relatively close or separate, thereby locking the extension of the cutter 5. In this setting, the locking nut 14 is located outside the pressing block 4 for easy operation by the user. When the locking nut 14 is rotated, the threaded rod 13 drives the relevant components to move under the action of the locking nut 14, making the clamping member 3 and the pressing block 4 relatively close or separate. When the two are relatively close, the cutter 5 extends and is locked, which facilitates cleaning of the cutter 5. When the two are relatively separated, the cutter 5 retracts into the dividing cover 2 under the action of the return spring 9.

[0027] The implementation principle of a novel tablet medicine divider in this embodiment is as follows: In the initial state, the compression spring 8 inside the dividing cover 2 applies a downward pushing force to the clamping member 3 through the first connecting ring 6, so that the clamping member 3 maintains a downward pressing tendency, while the reset spring 9 connects the pressing block 4 and the clamping member 3 through the second connecting ring 7, and applies an upward pushing force to the pressing block 4, so that the cutter 5 naturally retracts into the dividing cover 2, avoiding exposure and accidental injury.

[0028] In use, first place the tablet in the positioning groove 15 of the base 1. The V-shaped structure at both ends of the positioning groove 15 can automatically calibrate the position of the tablet to ensure that the center line of the tablet is aligned with the center of the divider. Then, install the divider cover 2 by the limiting block 17 of the base 1 and the limiting groove 18 of the divider cover 2. At this time, the tablet will push the pressing member 3 upward due to its own thickness. The compression spring 8 is compressed and generates a reverse elastic force. The pressing member 3 applies continuous pressure to the tablet to achieve stable positioning of the tablet and prevent the tablet from sliding or shifting.

[0029] When splitting the tablet, press down on the pressing block 4, and the cutter 5 moves down accordingly. The return spring 9 is compressed, and the cutter 5 continues to move down after contacting the tablet until the tablet is completely split. The clearance groove 16 on the base 1 provides space for the cutter 5 to move down, preventing the cutter 5 from contacting the base 1 and being damaged. After the splitting is completed, release the pressing block 4, and the elastic force of the return spring 9 pushes the pressing block 4 to reset. The cutter 5 then retracts into the splitting cover 2, restoring the initial safe state.

[0030] When it is necessary to clean the cutter 5, rotate the locking nut 14 on the outside of the pressing block 4. Under the engagement of the locking nut 14, the threaded rod 13 drives the crossbar 12 and the connecting rod 10 to move along the sliding groove 11 of the pressing block 4, so that the clamping member 3 and the pressing block 4 are relatively close. The return spring 9 and the compression spring 8 are compressed, the cutter 5 extends and remains locked. At this time, the cutter 5 can be safely cleaned. After cleaning, rotate the locking nut 14 in the opposite direction to loosen it. The elastic force of the return spring 9 pushes the pressing block 4 to reset, and the cutter 5 retracts again, returning to the safe storage state.
