Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a medicine distributor. Background Art

[0002] Many drugs exist in the form of tablets, and the dosage of a single tablet is relatively large compared to the single dosage of infants and young children. Children are not reduced adults. As a special group of drug users, they have their own unique physiological characteristics. Therefore, children at different stages have different absorption, distribution, metabolism and excretion capabilities of drugs, and they must not be converted based on weight, age or body surface area alone. The drug treatment of pediatric diseases is much more complicated than that of adults. The treatment plan should be determined according to the characteristics of children at different stages and the specific condition. Before children need to take medicine, different amounts of medicine need to be divided. At present, the existing operations are mostly nurses cutting with scissors or breaking with their hands. For 1 / 2 tablets and 1 / 4 tablets, they can still be cut and evenly distributed, but for 1 / 3 tablets, 1 / 5 tablets...1 / 10 tablets or more subdivided, the current cutting method cannot evenly distribute them. The tablets can be ground and diluted with water for distribution, but this is likely to lead to drug contamination and waste.

[0003] After searching, the Chinese patent application with application number 202221596866.X discloses a micro-dose dispenser for infants and young children, including a cutting support chassis, a covering end cover and a circular pressing tablet. The cutting support chassis is provided with a limit assembly for limiting the movement of tablets. The covering end cover is rotatably arranged on the cutting support chassis. A circular sleeve is vertically arranged on the covering end cover. A pressing rod is movably arranged in the circular sleeve. There are multiple circular pressing tablets, each of which is equipped with a different number of dividing blades. The circular pressing tablets can be selectively detachably connected to one end of the pressing rod close to the cutting support chassis. The circular pressing tablets with different numbers of dividing blades of the utility model are installed at one end of the pressing rod. Through simple operation, the tablets can be cut into 1 / 5 tablets...1 / 10 tablets or more finely.

[0004] The medicine divider can divide the tablets evenly, but during operation, it is necessary to replace the circular tablets with different numbers of dividing blades according to the fractions of the cut tablets. The operation is time-consuming and may cut the hands during replacement. In addition, the remaining circular tablets need to be stored in a separate container, which is inconvenient to use.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0031] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] The inventors have found that in clinical practice, infants and young children are usually given medication based on their weight, so the tablets need to be divided into the required equal portions and taken in the required amount. Existing medicine dividers or scissors cannot divide the tablets into more portions and ensure that each portion has an equal dose, which leads to the technical problem of inaccurate medication dosage for infants and young children.

[0033] Based on the above findings, the present application provides a medicine splitter, comprising a tablet splitting mechanism 1 and a tablet clamping mechanism 2 arranged above the tablet splitting mechanism 1, wherein the tablet clamping mechanism 2 is connected to the center of the tablet splitting mechanism 1 via a limiting mechanism 3 arranged at the tail end. Embodiment 1

[0034] Reference Figure 1-2 As shown, the present application provides a medicine divider, including a tablet splitting mechanism 1 and a tablet clamping mechanism 2 arranged above the tablet splitting mechanism 1, and the tablet clamping mechanism 2 is connected to the center of the tablet splitting mechanism 1 through a limiting mechanism 3 arranged at the tail end.

[0035] In the above technical solution, the tablet clamping mechanism 2 is matched with the tablet splitting mechanism 1 through the limiting mechanism 3 to achieve one-to-one correspondence and pressing cutting. Specifically, the limiting mechanism 3 can drive the tablet clamping mechanism 2 to rotate so that it reaches the required position to form an upper and lower correspondence with the tablet splitting mechanism 1, and then the tablet clamping mechanism 2 is driven to approach the tablet splitting mechanism 1 by pressing the limiting component 3 so that the tablet is split.

[0036] Furthermore, the tablet splitting mechanism 1 includes a chassis 11 and a blade seat 13 evenly arranged in the circumferential direction of the chassis 11, and the blade seat 13 is provided with blades 14 of different equal parts. A slide groove 15 is opened at the center of the chassis 11, and a spring A16 is connected to the slide groove 15.

[0037] Specifically, the blade holder 13 is a cylindrical structure and the number is 9. Each blade holder 13 is fixedly connected with blades 14 of different equal parts, such as two equal parts, three equal parts, ... ten equal parts, and the tablets are cut into corresponding equal parts at one time by the blades 14 of equal parts. The circumference of the blades 14 is smaller than the circumference of the blade holder 13, which facilitates the installation of the blade holder 13.

[0038] Reference Figure 4 As shown, the limiting mechanism 3 includes a limiting cylinder 31 connected to the spring A16, one end of the limiting cylinder 31 cooperates with the slide groove 15, and the other end is connected to the universal ball head 32, and the rear end of the universal ball head 32 is connected to the rotating arm 33.

[0039] In detail, the limiting cylinder 31 is a hollow cylindrical structure with a closed lower end and an open upper end, and 9 arc-shaped notches are evenly opened at the upper end of the limiting cylinder 31, and the universal ball head 32 cooperates with the arc-shaped notches for limiting.

[0040] It should be noted that, through the rotational connection between the limiting cylinder 31 and the universal ball head 32, the axial and radial rotation of the rotating arm 33 can be realized, which is convenient for placing and fixing tablets in the tablet clamping mechanism 2, and axially rotating to limit and cut the tablets.

[0041] Reference Figure 5 As shown, in a further embodiment, the tablet clamping mechanism 2 includes a clamping plate 21 disposed on a rotating arm 33, a plurality of springs B22 are disposed inside the clamping plate 21, and ends of the springs B22 are each connected to a clamping block 23.

[0042] Specifically, the number of the spring B22 and the number of the clamping block 23 are respectively set to 3.

[0043] In particular, the clamping block 23 is a trapezoidal structure with an arc slope inside that gradually expands from bottom to top. When the three clamping blocks 23 are close together, a circular structure is formed at the bottom to clamp smaller tablets, and the inclined space at the top can ensure that the blade 14 contacts the clamped tablets. Embodiment 2

[0044] Based on Example 1, refer to Figure 3 As shown, this embodiment provides a detachable connection method between the chassis 11 and the blade seat 13.

[0045] Specifically, the chassis 11 is evenly provided with threaded holes 12 in the circumferential direction, and the bottom of the blade seat 13 is provided with external threads. The external threads of the blade seat 13 are connected with the internal threads of the threaded holes 12 through threads, so as to facilitate replacement during use.

[0046] Reference Figure 4 As shown, in order to more conveniently rotate the rotating arm 33 during operation, a handle 34 is provided on the rotating arm 33 , and the handle 34 is a U-shaped structure. During operation, the movement of the rotating arm 33 is achieved by pulling and pressing the handle 34 .

[0047] Specific application cases

[0048] Taking the dosage of digoxin tablets for infants and young children as an example, the specific application of a medicine splitter in the present application in splitting digoxin tablets is described in detail.

[0049] The dosage of digoxin for infants and young children is usually calculated according to their weight. The dosage of digoxin for infants and young children is: 0.02-0.03 mg / kg for premature infants, 0.03-0.04 mg / kg for newborns under 1 month old, 0.05-0.06 mg / kg for 1-2 years old, 0.03-0.04 mg / kg for 2-5 years old, and 0.02-0.03 mg / kg for 5-10 years old.

[0050] The tablets need to be cut into equal portions according to the specific weight of the child and then taken according to the dosage. Based on the above situation, the present application provides a medicine divider that can divide the tablets into 10 equal portions at a minimum. During the specific operation, the handle 34 is pulled to make the rotating arm 33 drive the clamping disk 21 to rotate in the radial direction, and rotate 180 degrees from reverse to forward, and then put the tablets into the space formed by the clamping block 23 for clamping and fixing. At this time, the spring B22 is compressed.

[0051] After the tablet is clamped and fixed, continue to pull the handle 34 so that the rotating arm 33 drives the clamping disk 21 to rotate. According to the required equal cutting, the universal ball head 32 is moved to the arc-shaped notch at the upper end of the limiting cylinder 31 corresponding to the equal-dividing blade 14 for limiting. Then, press the handle 34 to drive the clamping disk 21 to move closer to the blade 14 to cut the tablet.

[0052] During the downward pressing and cutting process, the spring A is compressed, the limiting cylinder 31 moves downward in the slide groove 15, and the blade 14 squeezes the clamping block 23 so that the clamping block 23 moves outward, and the spring B is compressed. After the cutting is completed, the handle 34 is released, and the spring A returns to its original state to drive the limiting cylinder 31 to move upward, thereby driving the clamping plate away from the blade, and finally the cut tablets can be collected.

[0053] In summary, although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
