Description

Technical Field

[0001] The utility model relates to a cutting technology for finished tablets, in particular to a medicine cutting box. Background Art

[0002] Hospitals or clinics may need to cut tablets for the following reasons:

[0003] 1. Based on the specific situation of a specific patient, a specific drug dosage will be matched for the patient. The drug dosage for a specific patient is not an integer multiple of the tablets.

[0004] 2. Some patients have difficulty swallowing and need to reduce the size of the tablets.

[0005] 3. In some cases, it is necessary to cut the tablets in order to control the release rate of the drug in the human body.

[0006] When chronic patients take medicine at home, they often cut the tablets for several days in advance.

[0007] Typically, after cutting tablets, hospitals or clinics package the tablets with other medications and give them to patients. However, once the tablets are cut, the cut surfaces are exposed to the air. Without the protective film, the tablets may be more susceptible to moisture, deterioration, or chemical reactions with other medications, leading to contamination and thus affecting their efficacy.

[0008] Therefore, one of the research and development ideas of the present invention is to develop a technology that automatically seals the cut surface of the finished tablets after they are cut to meet the specific needs of specific patients, so that the cut surface is exposed, causing the tablets to get damp, deteriorate, or react chemically with other tablets.

[0009] Existing tablet cutting devices can only cut tablets into halves (cutting them into two pieces). To cut finished tablets into quarters (cutting them into four pieces), the finished tablets must be cut twice, both horizontally and vertically. This is cumbersome, especially since the first cut breaks the finished tablet into two halves, which then need to be joined together and rotated 90 degrees before being cut again. These manual operations are extremely cumbersome, and often result in irregular tablet fragments after the second cut because the two halves are not perfectly joined after the first cut or the rotation angle is not exactly 90 degrees.

[0010] The second research and development idea of ​​the present invention is to design a technology that does not require the replacement of blades. In one cutting action, the tablet can be cut into two or four pieces. This achieves the goal of selectively cutting the finished tablet into two or four pieces at one time without replacing the blade.

[0011] Regarding the problem of cutting finished tablets, the existing medicine cutting devices on the market have a small amount of medicine to be loaded and a single medicine cutting mode. They are only suitable for one person or a family and cannot meet the needs of supplying medicine to multiple people.

[0012] The third research and development idea of ​​the present invention is to develop a medicine cutting device to meet the needs of supplying medicine to multiple people.

[0013] Most of the current medicine cutting devices on the market require manual operation by the user. Due to the presence of blades, if used by the elderly or children, they may cause skin scratches or even more serious injuries. The fourth research and development idea of ​​the present utility model is to develop a medicine cutting device that can avoid injuries during the cutting process. Utility Model Content

[0014] The purpose of the present invention is to implement the second research and development idea and provide a cross-shaped blade that does not require blade replacement and can cut a finished tablet into two or four pieces in one cutting action.

[0022] A vertically transparent channel groove is provided at the radially outer end of the upper carrier plate. A vertical displacement device is connected to one side of the housing. The vertical displacement device is a linear motor or a roller screw. The vertical displacement device includes a displacement member. The channel groove is used to allow the displacement member to pass up and down through the upper carrier plate. An electronic control device is connected to the vertical displacement device and controls the vertical displacement of the displacement member.

[0023] The displacement member is connected to a micro negative pressure pump, which is connected to a medicine taking suction nozzle, which is arranged downward and is used to suck finished tablets; the micro negative pressure pump is connected to an electronic control device;

[0024] A vertical shaft is fixedly connected between the center of the top wall and the center of the bottom wall of the shell, and the upper carrier plate is rotatably connected to the vertical shaft through a bearing; the vertical shaft is rotatably connected to the upper driven gear through a bearing, and the upper driven gear is fixedly connected to the upper carrier plate; the vertical shaft is connected to the upper motor frame, and the upper motor frame is connected to the upper micro motor, and the output shaft of the upper micro motor is downwardly connected to the upper driving gear, and the upper driving gear is meshed with the upper driven gear;

[0025] One of the multiple upper medicine storage tanks serves as a gelatin sheet storage tank, which is used to hold gelatin sheets made of edible gelatin. Before cutting the finished tablets, a layer of gelatin sheet is placed under the finished tablets and a layer of gelatin sheet is placed on top of the finished tablets. An electric heating plate is provided on the top wall of the inner cavity of the support platform, and two electric heating plates are symmetrically arranged about the knife gap. Both electric heating plates are connected to the electronic control device.

[0026] The vertical shaft below the upper carrier plate is rotatably connected to the lower carrier plate through a bearing, and the vertical shaft at the lower carrier plate is rotatably connected to the lower driven gear through a bearing, and the lower driven gear is fixedly connected to the lower carrier plate; the vertical shaft is connected to the lower motor frame, and the lower motor frame is connected to the lower micro motor, and the output shaft of the lower micro motor is downwardly connected to the lower driving gear, and the lower driving gear is meshed with the lower driven gear;

[0029] Several baffles are provided on the upper surface of the support platform, and the horizontal cross-sections of each baffle are located on the circumference of the same circle, and the center of the circle is located at the midpoint of the knife gap; each baffle forms a positioning groove for positioning the tablets; the support platform is made of ferromagnetic material, and the baffles are embedded with ferrite permanent magnets, and the baffles are fixed to the support platform by magnetic adsorption.

[0030] The purpose of the present invention is also to provide a medicine cutting box, which can realize the storage and cutting of tablets, meet the storage and cutting needs of hospitals, pharmacies and patients' families, and avoid the problems of manual cutting of medicines, such as the medicine being cut into pieces and the large difference in the size of the broken tablets after cutting.

[0031] The utility model has the following advantages:

[0032] The cross-shaped blade has a simple structure and is easy to use. Simply create a slit on the surface of the platform that supports the finished tablets for the main blade's blade to pass downward through. This allows the auxiliary blade to continue cutting downward until its blade reaches the surface of the platform, thereby cutting the finished tablet into four pieces. Because the height difference D is greater than or equal to the tablet thickness, if the finished tablet needs to be cut into two pieces, the cutting only needs to be stopped when the main blade's blade reaches the surface of the platform. At this point, the auxiliary blade has not yet contacted the tablet, so the finished tablet can be cut into two pieces. Whether cutting into two or four pieces, there is no need to change blades, making it very convenient to use.

[0033] The cross-shaped blade can flexibly and conveniently control the number of petals of the broken tablets after cutting by controlling the cutting depth without changing the blade, and it is easier to evenly divide the finished tablets.

[0034] The electric actuator controller controls the downward displacement of the cross-shaped blade to control whether the finished tablet is cut into two or four pieces, making it very convenient to use. The blade gap, combined with the height difference D being greater than or equal to the tablet thickness, provides structural support for using the cross-shaped blade to cut the finished tablet into two or four pieces.

[0035] The medicine cutting action in the utility model occurs inside the housing, so the blade cannot hurt the user, thus avoiding injury accidents during the medicine cutting process.

[0036] Multiple upper medicine storage troughs can store a variety of finished tablets in different categories, making cutting more convenient for patients who need to take multiple tablets, as well as for hospitals, pharmacies, and other institutions that need to cut large quantities of medicine. For patients who need to take medicine, the multiple upper medicine storage troughs can also serve as a storage function when cutting is not needed. Patients do not need to search for multiple medicine bottles and boxes when taking medicine. They can just go to the medicine cutting box to get the multiple medicines they need.

[0037] During use, the electronic control device controls the vertical position of the medicine dispensing nozzle via a vertical displacement mechanism. When the medicine dispensing nozzle is inserted into a medicine storage tank, the negative pressure generated by the negative pressure pump causes the nozzle to absorb a finished tablet. At this point, the medicine dispensing nozzle is blocked by the finished tablet and thus cannot absorb further finished tablets. By utilizing the vertical displacement mechanism, combined with the rotary drive structure formed by the micromotor, driving gear, and driven gear, the present utility model can conveniently remove finished tablets from a specific medicine storage tank and place them on the support platform.

[0038] Before cutting the finished tablets, place a layer of gelatin sheet under the finished tablets and cover the top of the finished tablets with a layer of gelatin sheet. In this way, after cutting, the gelatin sheet will naturally cover the broken tablets including their cut surfaces, which can effectively isolate the air and contamination from other tablets. After electric heating, the upper and lower gelatin sheets can be adhered and stably wrap the broken tablets after cutting, better avoiding the exposure of the cut surface (cut surface) of the tablets, resulting in the tablets getting damp, deteriorating or chemically reacting with other tablets. It is especially suitable for use in situations where the dosage for several days is cut at a time (such as when doctors pack medicine for patients).

[0039] The base is preferably made of 430 stainless steel, which is magnetically attracted. Each baffle is embedded with a ferrite permanent magnet, which allows the baffle to be firmly attached to the base to position the tablets. When needed, the position of each baffle can be flexibly adjusted to form areas of different sizes to accommodate tablets of different sizes.

[0040] The center of the circle (inscribed circle) enclosed by each baffle is located at the midpoint of the knife gap, so that the main blade can just divide the tablet into two halves.

[0041] The utility model is convenient for manual use, flexible and convenient to use, and the user can set the timing reminder function in advance.

[0042] Because a layer of gelatin is applied to the bottom and top of the finished tablet before cutting, the gelatin sheet adheres to and envelops the broken tablets after cutting, isolating them from air and other broken tablets. In hospitals and pharmacies, several days' worth of medication can be packaged for patients at once without worrying about the broken tablets getting wet or reacting with each other.

[0043] After the cutting action, the upper and lower gelatin sheets adhere to the broken tablets, significantly isolating the broken tablets from air and other tablets. The upper and lower gelatin sheets adhere to each other, which can enhance the gelatin sheet's ability to isolate the broken tablets from air and other tablets.

[0044] In summary, the present invention offers advantages such as medication storage and cutting, preventing broken tablets from becoming damp and reacting after cutting several days' worth of tablets at once, and providing a timed reminder for patients to take their medications. The present invention is easy to control and can be controlled manually or semi-automatically. Semi-automatic control means that operations such as storing and removing broken tablets still require manual intervention.

[0045] The tablets cut by the medicine cutting box of the utility model are wrapped with a layer of edible gelatin sheet, so that the broken tablets (not broken into powder, but incomplete tablet petals formed after cutting) are isolated from air and other medicines, ensuring the safety and efficacy of the broken tablets (tablet petals).

[0046] This utility model can cut tablets in a timely and quantitative manner according to the operator's requirements, reducing the pharmacist's workload and allowing them to focus more time on patient care and medication guidance. At the same time, the automated medicine cutting box can reduce human errors in the distribution of cut tablets, improving patient medication safety.

[0047] With the digital transformation of the medical industry, automated medicine cutting boxes can be seamlessly connected with hospital information systems to achieve automation and informatization of drug management.

[0048] At the same time, the automatic medicine cutting box of the present invention can properly preserve the broken medicines after tablet cutting, meeting the process of medicine cutting and storage needs of hospitals or clinics, so that hospitals or clinics can smoothly supply medicines during peak traffic periods.

[0055] like Figures 1 to 4As shown, the cross-shaped blade of the present invention includes a main blade 1 and an auxiliary blade 2. The main blade 1 has a vertical through-slot (a slot that is transparent in a direction perpendicular to the main blade) in the middle. The auxiliary blade 2 passes through the through-slot and is fixedly connected (e.g., welded) to the main blade 1. The main blade 1 and the auxiliary blade 2 are arranged perpendicular to each other in a cross-shaped pattern. The cutting edge of the auxiliary blade 2 is higher than the cutting edge of the main blade 1 by a height difference D, which is greater than the thickness of the finished tablet to be cut. The main blade 1 is used to cut the finished tablet into two pieces.

[0056] When cutting the finished tablet into two halves, the cutting edge of the main blade 1 stops cutting when it cuts the bottom surface of the finished tablet;

[0057] When the finished tablet is cut into four pieces, the cutting is stopped when the cutting edge of the auxiliary blade 2 cuts the bottom surface of the finished tablet.

[0058] The cross-shaped blade has a simple structure and is easy to use. It only needs to set a slit on the surface of the support platform that supports the finished tablets for the blade of the main blade 1 to pass downward, and the auxiliary blade 2 can continue to cut downward until the blade of the auxiliary blade 2 reaches the surface of the support platform that supports the finished tablets, thereby cutting the finished tablet into four pieces. Because the height difference D is greater than or equal to the thickness of the tablet, when the finished tablet needs to be cut into two pieces, it is only necessary to stop cutting when the blade of the main blade 1 reaches the surface of the support platform that supports the finished tablets. At this time, the auxiliary blade 2 has not yet contacted the tablet, so the finished tablet can be cut into two pieces. Whether cutting into two or four pieces, there is no need to replace the blade, which is very convenient to use.

[0059] like Figures 1 to 6 As shown, the utility model also discloses a medicine cutting box using the cross-shaped blade, comprising a housing 3, a motorized push rod 4 fixedly connected to the top of the housing 3, the motorized push rod 4 having a controller 5, an extension rod of the motorized push rod 4 downwardly connected to the cross-shaped blade; the controller 5 of the motorized push rod 4 is connected to an electric control device 6; the electric control device is integrated with a touch screen 7 and installed together. Figure 5 The electronic control unit is not shown separately.

[0060] An upper carrier plate 15 is provided within the housing 3. The upper carrier plate 15 is provided with a plurality of upper medicine storage slots 16 for storing finished tablets, one of which serves as a medicine outlet slot 17 for outputting cut, crushed tablets. A support 18 is provided on the upper carrier plate 15 for carrying the cut finished tablets. The support 18 has an inner cavity, and a slit 19 is provided on the upper surface of the support 18 for the main blade 1 to extend downwardly below the upper surface of the support 18. The slit 19 communicates downwardly with the cavity within the support 18. The main blade 1 is disposed above and opposite the slit 19.

[0061] A medicine loading door 20 for loading and unloading medicines is provided on the side wall of the housing 3, corresponding to the upper carrier plate 15. Each upper medicine storage tank 16 is a radially pull-out structure relative to the upper carrier plate 15. Each upper medicine storage tank 16 is open at its upper end. The radial outer wall of each upper medicine storage tank 16 is a circular arc surface, and the diameter of the circular arc surface is the same as the outer diameter of the upper carrier plate 15. A handle 21 is provided on the radial outer wall of each upper medicine storage tank 16. The handle 21 is used to manually pull the upper medicine storage tank 16 radially outward.

[0062] An electric control device 6 and a touch screen 7 connected to the electric control device 6 are provided on the side wall of the housing 3 . The touch screen 7 faces outward for use by an operator. The electric control device 6 is connected to the electric push rod 4 .

[0063] The electronic control device 6 is a single chip microcomputer, a PLC, or a Raspberry Pi small single board computer. When using a Raspberry Pi small single board computer, a low-cost Raspberry Pi PicoW or Raspberry Pi Zero model can be used, and of course other more expensive models of Raspberry Pi small single board computers can also be used.

[0064] By controlling the downward displacement of the cross-shaped blade by the controller 5 of the electric push rod 4, the finished tablet can be cut into two or four pieces, which is very convenient. The blade slit 19, combined with the height difference D being greater than or equal to the tablet thickness, provides structural support for using the cross-shaped blade to cut the finished tablet into two or four pieces.

[0065] The multiple upper medicine storage slots 16 can store a variety of finished tablets in different categories, which is convenient for patients who need to take a variety of tablets, as well as for hospitals, pharmacies and other units that need to cut a large number of medicines. For patients who need to take medicine, the multiple upper medicine storage slots 16 can also play a medicine storage function when they do not need to cut the medicine. When taking medicine, patients do not need to look for multiple medicine bottles and boxes, but only need to go to the medicine cutting box to get the multiple medicines they need.

[0066] A vertically transparent channel slot 22 is provided at the radially outer end of the upper carrier plate 15. A vertical displacement device 8 is connected to one side of the housing 3. The vertical displacement device 8 is a linear motor or a roller screw. The vertical displacement device 8 includes a displacement member 23. The channel slot 22 is used to allow the displacement member 23 and its connected components (the micro-negative pressure pump 9 and the medicine suction nozzle 24) to pass vertically through the upper carrier plate 15. The electronic control device 6 is connected to the vertical displacement device 8 and controls the vertical displacement of the displacement member 23.

[0067] The displacement member 23 is connected to a micro negative pressure pump, which is connected to a medicine taking nozzle 24, which is set downward and is used to suck finished tablets; the micro negative pressure pump 9 is connected to the electronic control device 6;

[0068] A vertical shaft 25 is fixedly connected between the center of the top wall and the center of the bottom wall of the housing 3. The upper carrier plate 15 is rotatably connected to the vertical shaft 25 via a bearing. The vertical shaft 25 is rotatably connected to an upper driven gear 26 via a bearing. The upper driven gear 26 is fixedly connected to the upper carrier plate 15. The vertical shaft 25 is connected to an upper motor frame 27. The upper motor frame 27 is connected to the upper micro motor 10. The output shaft of the upper micro motor 10 is downwardly connected to an upper driving gear 28. The upper driving gear 28 meshes with the upper driven gear 26.

[0069] During use, the electronic control device 6 controls the vertical position of the medicine dispensing nozzle 24 via the vertical displacement device 8. When the medicine dispensing nozzle 24 is inserted into a medicine storage tank, the negative pressure generated by the negative pressure pump causes the medicine dispensing nozzle 24 to absorb a finished tablet. At this time, the medicine dispensing nozzle 24 is blocked by the finished tablet and thus does not absorb any more finished tablets. By utilizing the vertical displacement structure, in conjunction with the rotary drive structure formed by the micromotor, the driving gear, and the driven gear, the present utility model can conveniently draw finished tablets from a specific medicine storage tank and place them on the support platform 18.

[0070] When a linear motor is used, the displacement member 23 is the mover of the linear motor and the electronic control device 6 is connected to the linear motor. When a roller screw is used, the lead screw of the roller screw is connected to the lead screw motor via a coupling, the displacement member 23 is the nut component of the roller screw, and the electronic control device 6 is connected to the lead screw motor of the roller screw (using a stepper motor).

[0071] One of the multiple upper drug storage tanks 16 serves as a gelatin sheet storage tank 29, which is used to hold gelatin sheets made from edible gelatin. Before cutting the finished tablets, a layer of gelatin sheets is placed underneath and another layer of gelatin sheets is placed on top. The gelatin sheets are preferably 1-2 mm thick. Two electric heating plates 11 are symmetrically positioned about the slit 19 on the top wall of the inner cavity of the support platform 18 and are connected to the electronic control device 6.

[0072] The gelatin sheet storage groove 29 and the medicine outlet groove 17 are preferably arranged adjacent to the support platform 18 on both sides of the circumference of the support platform 18, so that the path for placing the gelatin sheet from the gelatin sheet storage groove 29 to the support platform 18 is shortened, and the path for placing the cut broken tablets from the support platform 18 to the medicine outlet groove 17 is shortened.

[0073] Before cutting the finished tablets, place a layer of gelatin sheet under the finished tablets and cover the top of the finished tablets with a layer of gelatin sheet. In this way, after cutting, the gelatin sheet will naturally cover the broken tablets including their cut surfaces, which can effectively isolate the air and contamination from other tablets. After electric heating, the upper and lower gelatin sheets can be adhered and stably wrap the broken tablets after cutting, better avoiding the exposure of the cut surface (cut surface) of the tablets, resulting in the tablets getting damp, deteriorating or chemically reacting with other tablets. It is especially suitable for use in situations where the dosage for several days is cut at a time (such as when doctors pack medicine for patients).

[0074] The vertical shaft 25 below the upper carrying plate 15 is rotatably connected to the lower carrying plate 30 through a bearing, and the vertical shaft 25 at the lower carrying plate 30 is rotatably connected to the lower driven gear 31 through a bearing, and the lower driven gear 31 is fixedly connected to the lower carrying plate 30; the vertical shaft 25 is connected to the lower motor frame 32, and the lower motor frame 32 is connected to the lower micro motor 12, and the output shaft of the lower micro motor 12 is downwardly connected to the lower driving gear 33, and the lower driving gear 33 is meshed with the lower driven gear 31; in the utility model, the upper micro motor 10 and the lower micro motor 12 are preferably stepper motors.

This lower carrier tray 30 primarily serves to increase the storage capacity of the present invention. The electronic control unit 6 is connected to a barcode scanner 13 for scanning barcodes on drug packaging to obtain drug information. A medicine dispensing door 36 is provided on the sidewall of the housing at the lower carrier tray 30.

[0076] The top surface of the support 18 is provided with a number of baffles 35 . The horizontal cross-sections of each baffle 35 lie on the circumference of a circle centered at the midpoint of the slit 19 . Each baffle 35 forms a positioning slot for positioning the tablets. The support 18 is made of ferromagnetic material, and the baffles 35 are embedded with ferrite permanent magnets, which are magnetically fixed to the support 18 . The ferrite permanent magnets are conventional and not shown.

[0077] The support platform 181 is preferably made of 430 stainless steel, which is magnetically attractive. Each baffle 35 is embedded with a ferrite permanent magnet, allowing it to be securely attached to the support platform 18 to position the tablets. The position of each baffle 35 can also be flexibly adjusted when needed, allowing each baffle 35 to enclose areas of varying sizes to accommodate tablets of different sizes. The ferrite permanent magnet can be barium ferrite or barium strontium ferrite.

[0078] The center of the circle (inscribed circle) enclosed by each baffle 35 is located at the midpoint of the blade slit 19, so that the main blade 1 can just divide the tablet into two halves.

[0079] The electronic control device 6 is connected to a speaker 14, which can be replaced by a buzzer. The utility model also discloses a method for using the above-mentioned medicine cutting box, which is carried out in the following steps:

[0082] When the extension rod of the electric push rod 4 is retracted, the distance between the main blade 1 and the upper surface of the support platform 18 is L1 (mm), and the distance between the auxiliary blade 2 and the upper surface of the support platform 18 is L2 (mm). The extension amount L1 of the electric push rod 4 for cutting the finished tablet into two pieces and the extension amount L2 of the electric push rod 4 for cutting the finished tablet into four pieces are pre-stored in the electronic control device 6.

[0083] The initial position of the displacement member 23 is between the upper carrier plate 15 and the lower carrier plate 30;
