[0002] Tablets play an important role in drug treatment due to their advantages of stable quality, accurate dosage, relative safety, and convenience of taking. They are the most commonly used oral drug dosage form for patients. When prescribing medicine for patients, doctors generally need to prescribe different dosages for different patients according to factors such as age, condition, and weight. Therefore, it is often necessary to split the tablets for use, such as reducing a single dose to 1 / 2, 1 / 3, or 1 / 4 of a tablet. At present, splitting methods such as manual breaking and scissor cutting are commonly used in clinical practice, but they all have defects such as inaccurate dosage of split tablets, which cannot reach the therapeutic dose, thus affecting the treatment effect. In addition, the manual breaking method is unhygienic, and the scissor cutting method will also cause tablets to be difficult to locate, resulting in fragments and tablets falling during the cutting process, causing pollution, waste, and even dangerous events such as hand injuries.

[0033] This embodiment provides a tablet cutter, such as Figure 1-3As shown, it includes a medicine box 1, a medicine loading platform 2, a medicine cutting component 3 and a limiting structure; wherein the medicine box 1 includes a box body 11 and an openable and closable box cover 12; a guide hole 121 is provided on the box cover 12; the medicine loading platform 2 is fixedly arranged inside the box body 11, and has a plurality of coaxial annular steps 21 arranged in sequence from top to bottom and a knife groove 22 that simultaneously penetrates the plurality of the annular steps 21; the inner diameters of the plurality of the annular steps 21 gradually decrease from top to bottom; the knife groove 22 passes through the axis of the medicine loading platform 2 and extends outward; the medicine cutting component 3 includes a handle 31 and a knife 32 installed at one end of the handle 31; the handle 31 passes through the guide hole 121 and is movably installed on the box cover 12 up and down, the knife 32 is located inside the box cover 12, and the free end of the handle 31 is located outside the box cover 12; a limiting structure is arranged on the guide hole 121 and the handle 31, and is used to limit the position of the knife 32 so that it can be opposite to the knife groove 22 up and down.

[0034] When using the tablet cutter of this embodiment, first select the matching annular step 21 according to the specifications of the tablets, and then put the tablets into the selected annular step 21. At this time, the tablets are positioned by the inner side wall of the annular step 21 and supported by the top surface of the annular step 21 of the next layer for carrying tablets (or the inner top surface of the bottom of the box body 11 for carrying tablets); cover the box cover 12 on the box body 11, and then press the handle 31 downward. Under the limiting effect of the limiting structure, the knife 32 accurately enters the knife groove 22 and cuts the tablets. The drug loading platform 2 has a plurality of coaxial annular steps 21 with inner diameters gradually reduced from top to bottom. Tablets of different specifications can be placed in the middle of each annular step 21, so that tablets of different specifications can be cut. The number of annular steps 21 can be two, three, four, five, etc. The specific number can be increased or decreased according to the specifications of the existing tablets, and this application does not limit this.

[0035] In the tablet cutter of this embodiment, the limiting structure includes a first limiting portion 122 provided on the box cover 12 for circumferentially limiting the handle 31, and a second limiting portion 311 provided on the handle 31 for cooperating with the first limiting portion 122. In this embodiment, by limiting the circumferential position of the handle 31, the knife 32 can be accurately aligned with the knife groove 22, preventing the knife 32 from deviating during the process of cutting the tablets, thereby accurately cutting the tablets.

[0036] The pill cutter of this embodiment, further, the first limiting portion 122 is a limiting groove formed on the inner wall of the guide hole 121; the second limiting portion 311 is a long strip of limiting ribs formed on the outer peripheral wall of the handle 31 and extending along the length direction of the handle 31.

[0039] The tablet cutter of this embodiment further includes a return spring 33, which is sleeved and installed on the handle 31 and is located between the pressing portion 312 and the outer top wall of the box cover 12. In this embodiment, when the pressing portion 312 is pressed, the return spring 33 applies a return force opposite to the pressing direction to the pressing portion 312, so that the handle 31 can quickly return to its original position after the pressing force disappears.

[0040] The tablet cutter of this embodiment, further, the shape of the knife groove 22 is I-shaped, Y-shaped or X-shaped; the blade shape of the tool 32 is correspondingly designed to be I-shaped, Y-shaped or X-shaped. In this embodiment, knife grooves 22 of different shapes and corresponding tools 32 can cut tablets in different ways. For example, when the dosage of tablet medicine prescribed by the doctor is reduced to half, the knife groove 22 and tool 32 of I-shaped shape can be selected; when the dosage of tablet medicine prescribed by the doctor is reduced to one-third, the knife groove 22 and tool 32 of Y-shaped shape can be selected; when the dosage of tablet medicine prescribed by the doctor is reduced to one-quarter, the knife groove 22 and tool 32 of X-shaped shape can be selected.

[0041] The pill cutter of this embodiment further comprises a hinge 13, which is respectively arranged on the box body 11 and the box cover 12, and the box body 11 and the box cover 12 are rotatably connected via the hinge.

[0042] In the tablet cutter of this embodiment, the top surface of the annular step 21 for carrying tablets and the inner top surface of the bottom of the box body 11 for carrying tablets are designed with a curved surface with the middle being the low point. In this embodiment, when the size of the tablet cannot completely match the annular step 21 so that the outer diameter of the tablet cannot fit tightly against the vertical inner wall of the annular step 21, the curved surface design can automatically center the tablet inside the annular step 21, thereby preventing the tablet from being cut off.

[0043] In the tablet cutter of this embodiment, the box body 11 and the box cover 12 are designed separately. In this embodiment, by designing the box body 11 and the box cover 12 separately, the cutter 32 can move straight up and down during the process of cutting the tablets, avoiding the displacement of the tablets when pressing down.

[0044] The tablet cutter of this embodiment works as follows:

[0045] When it is necessary to cut the tablet, first select the matching annular step 21 according to the specifications of the tablet, and then put the tablet into the selected annular step 21, so that the tablet is positioned by the inner side wall of the annular step 21 and supported on the top surface of the annular step 21 of the next layer for carrying the tablet (or the inner top surface of the bottom of the box body 11 for carrying the tablet); since the top surface of the annular step 21 for carrying the tablet and the inner top surface of the bottom of the box body 11 for carrying the tablet are arc-shaped designs with the middle as the low point, the tablet is in the center position in the annular step 21; the box cover 12 is closed on the box body 11, and then the handle 31 is pressed downward, and under the limiting action of the limiting structure, the knife 32 accurately enters the knife groove 22 and cuts the tablet; after cutting, under the action of the reset spring 33, the handle 31 drives the knife 32 to quickly reset, thereby completing the cutting of the tablet.

[0046] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of this innovative technical solution.
