Description

Technical Field

[0001] The present invention relates to the technical field of drug comminution, and particularly to a drug comminution device. Background Art

[0002] The most common diseases in the department of respiratory medicine include upper respiratory tract infection, chronic bronchitis, chronic obstructive pulmonary disease, bronchial asthma, bronchiectasis, respiratory failure, pulmonary tuberculosis, pneumonia, interstitial lung disease, lung tumor, lung abscess, pneumothorax, and pleural effusion, etc.

[0003] Some of the most common clinical symptoms of the respiratory system mainly include cough, expectoration, dyspnea, shortness of breath, and even hemoptysis. Then, some patients may also have manifestations of some other diseases.

[0004] The physical conditions of patients in the department of respiratory medicine vary. Some patients may have difficulty swallowing or a decline in digestion and absorption ability due to the influence of diseases. In this case, comminuting the drug can make the drug more easily accepted and absorbed by the patient, thereby improving the compliance and effect of treatment.

[0005] Currently, manual grinding is mainly used clinically. In order to simplify the drug administration process, reduce the risk of drug contamination, and reduce drug waste, since the pharyngeal muscles of patients with dysphagia may have problems such as insufficient strength and poor coordination, when swallowing a capsule, it is difficult to smoothly push the capsule into the esophagus like a normal person through the precise contraction and relaxation of the pharyngeal muscles. The capsule usually has a certain volume and shape, and is relatively smooth and hard. For patients with dysphagia, a larger capsule may be difficult to pass smoothly through the oral cavity and pharynx, and is likely to get stuck in the pharynx or the bend of the esophagus. Moreover, the smooth surface of the capsule also increases the difficulty of swallowing. It is difficult for patients to push it down through the friction of the pharyngeal muscles like swallowing textured food. Due to the previous adverse experience of dysphagia or choking, patients often have a fear psychology when facing capsule drugs. Currently, patients with dysphagia are all administered through external changes or by the anal method, etc. To sum up, therefore, the present device provides a drug comminution device.

[0016] Furthermore, both the lower crushing chamber and the lower capsule mixing cavity are lined with food-grade stainless steel and have smooth and corrosion-resistant inner walls.

[0017] The above at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0018] First, this device can crush granular drugs to facilitate drug intake for patients with dysphagia or poor digestion and absorption ability, enabling better reception and absorption of drugs for effective treatment. At the same time, it can separate capsule drugs, mix them with warm water and then take them, or take them without separating the capsules and mixing them with warm water, effectively improving drug intake for patients with dysphagia or poor digestion and absorption ability.

[0019] This device integrates multiple functions such as crushing granular drugs and processing capsule drugs into one device, saving space and reducing the cumbersome processes brought about by operating multiple devices. It can be used more conveniently in hospital wards, pharmacies, or home medical environments, improving the utilization efficiency of medical resources.

[0020] This device can select a suitable drug intake method according to the patient's drug intake situation. It can crush and take granular drugs, or take capsules and mix them with water after separating the capsules, or take them by combining and crushing granular drugs and capsules.

[0021] This device can meet the drug intake needs of patients with dysphagia or poor digestion and absorption ability, and can centrally improve aspects such as drug absorption efficiency, adapt to individual patient differences, avoid drug waste, and improve the medication experience, so as to better meet clinical needs and has a certain market prospect.

[0022] Second, since the lower crushing chamber is threadedly connected to the lower end of the upper mating chamber, and the lower capsule mixing chamber is threadedly connected to the lower end of the upper capsule separation chamber. When the granular drugs in the lower crushing chamber are crushed and ready to be taken, by rotating the lower crushing chamber, the lower crushing chamber can be detached. At this time, warm water can be added to the lower crushing chamber to mix with the drugs for patients with dysphagia or poor digestion and absorption ability to take. The lower capsule mixing chamber can be detached by rotation. Pour warm water into the lower capsule mixing chamber, and use the lower capsule mixing chamber as a cup to cooperate with the lower crushing chamber to take the crushed drugs.

[0023] Thirdly, when patients with dysphagia take capsule drugs using this device, they can choose a suitable taking method according to the severity of their dysphagia. For patients with milder dysphagia, warm water can be poured into the lower capsule mixing chamber. Then, a straw with an inner diameter larger than that of the capsule drug, similar to a traditional milk tea straw, can be taken. Next, the capsule to be taken is placed into the lower capsule mixing chamber through the capsule placement hole. Then, the straw is inserted through the capsule placement hole and extends into the lower capsule mixing chamber to contact the warm water and is positioned above the required height of the warm water. At this time, the patient inhales the warm water inside the lower capsule mixing chamber through the straw. Affected by the suction force, the capsule will be sucked into the straw and inhaled synchronously with the warm water to achieve the taking of the capsule drug. This method facilitates the patient to better control the flow of water and the movement of the capsule, and inadvertently inhales and takes the capsule drug by inhalation. This method helps with swallowing, thus facilitating capsule drug taking for patients with milder dysphagia.

[0024] Fourthly, after the capsules of this device are separated, the liquid or suspension formed by mixing the drug with warm water is easier to pass through the throat and esophagus compared to intact capsules. Patients do not need to overcome the difficulty of swallowing capsules, reducing the risk of the capsule getting stuck in the throat or esophagus, thereby reducing the possibility of accidents such as choking and suffocation caused by swallowing. In addition, after the drug is mixed with warm water, its surface area increases, and the contact area with the gastrointestinal mucosa also increases correspondingly. This is conducive to the faster dissolution and absorption of the drug, thus enabling the drug to exert its efficacy faster. Especially for some drugs that need to take effect quickly, this method can make the drug enter the blood circulation faster to achieve the therapeutic purpose. At the same time, for patients with dysphagia, it is easier to take the drug, which will reduce their fear and resistance to taking medicine, thereby improving the compliance of taking medicine. Patients are more willing to take the medicine on time and in the correct dosage according to the doctor's advice, which helps with the treatment and recovery of the disease. However, the method of separating the capsules and mixing the drugs in this device is not applicable to all capsule drugs. For special dosage forms such as enteric-coated capsules and sustained-release capsules, opening the capsule will destroy their special drug release mechanism, which may cause the drug to be released at inappropriate sites, affecting the drug efficacy and even causing adverse reactions. Therefore, before using this method, it is necessary to consult a doctor or a pharmacist first to ensure the safety and effectiveness of drug use. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0040] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions of the present invention in combination with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0041] The following will detail the technical solutions provided by each embodiment of the present invention in combination with the drawings.

[0042] An embodiment of the present invention provides a drug crushing device, which includes a crushing and storage cavity 1 for storing particles to be broken, a crushing device 3 for crushing granular drugs, a driving device 2 for driving the operation of the crushing device 3, a capsule drug storage cavity 33 for storing capsule drugs for taking, a stirring and mixing device 4 for performing mixing operations in the capsule storage cavity, a transmission device 5 for driving the stirring and mixing device 4, and a capsule separation device 6 for separating capsules. The crushing and storage cavity 1 and the capsule drug storage cavity 33 are connected to each other and are horizontally placed. The driving device 2 is arranged at the upper end of the crushing and storage cavity 1 and its driving end extends into the interior of the crushing and storage cavity 1. The crushing device 3 is connected to the driving end of the driving device 2 and is located in the crushing and storage cavity 1. The stirring and mixing device 4 is located in the capsule drug storage cavity 33. The capsule separation device 6 is arranged inside the capsule drug storage cavity 33.

[0043] This device can crush granular drugs to facilitate drug taking by patients with dysphagia or reduced digestive and absorptive capacity, facilitating better reception and absorption of drugs for effective treatment. At the same time, it can separate capsule drugs, mix them with warm water and then take them, or take them without separating the capsules and mixing them with warm water, effectively improving drug taking by patients with dysphagia or reduced digestive and absorptive capacity.

[0044] This device integrates multiple functions of crushing granular drugs and processing capsule drugs into one device, saving space and reducing the cumbersome processes brought about by operating multiple devices. It can be used more conveniently in hospital wards, pharmacies, or home medical environments, improving the utilization efficiency of medical resources.

[0045] This device can select a suitable drug taking method according to the patient's drug taking situation. It can crush and take granular drugs, take capsules and mix them with water after capsule separation, or take them by combining and crushing granular drugs and capsules.

[0046] This device can meet the needs of patients with dysphagia or poor digestion and absorption ability for taking drugs, and can centrally improve drug absorption efficiency, adapt to individual differences of patients, avoid drug waste and improve the medication experience, etc., so as to better meet clinical needs and has a certain market prospect.

[0047] Preferably, the crushing and storage cavity 1 includes an outer cavity 11, an upper matching cavity 12, a lower crushing chamber 13, a feed tube 14 and a feed cover 15. A partition 16 is provided between the outer cavity 11 and the upper matching cavity 12. The outer cavity 11 and the upper matching cavity 12 are communicated by the feed tube 14. The feed cover 15 is arranged at the upper end of the feed tube 14. The lower crushing chamber 13 is threadedly connected to the lower end of the upper matching cavity 12.

[0048] Since the lower crushing chamber 13 is threadedly connected to the lower end of the upper matching cavity 12, and the lower capsule mixing cavity 35 is threadedly connected to the lower end of the upper capsule separation cavity 34. When the granular drug inside the lower crushing chamber 13 is broken and ready for taking, by rotating the lower crushing chamber 13 to separate it, at this time, warm water can be added to the lower crushing chamber 13 to mix with the drug for patients with dysphagia or poor digestion and absorption ability to take. The lower crushing chamber 13 can be removed by rotation. Pour warm water into the lower crushing chamber 13, and use the lower crushing chamber 13 as a cup to cooperate with the lower crushing chamber 13 to take the crushed drug.

[0049] Preferably, the driving device 2 includes a driving seat 21, a driving motor 22 and a driving shaft 23. The driving seat 21 is arranged at the upper end of the crushing and storage cavity 1. The driving motor 22 is arranged on the driving seat 21 and its output end faces downward. The output end of the driving motor 22 passes through the outside of the outer cavity 11 and penetrates into the inside of the outer cavity 11. The driving shaft 23 is arranged on the output end of the driving motor 22. The driving shaft 23 passes through the upper matching cavity 12 and is located inside the lower crushing chamber 13. The crushing device 3 includes a crushing shaft 31 and crushing blades 32. The crushing shaft 31 is arranged at the lower end of the driving shaft 23. The crushing blades 32 are arranged at the lower end of the crushing shaft 31. The crushing blades 32 are conical in shape. The inside of the lower crushing chamber 13 is conical and is in a state of being adapted to the shape of the spraying blades.

[0050] The physical conditions of patients in the respiratory department vary. Some patients may have difficulty swallowing or a decreased ability to digest and absorb due to the impact of the disease. In such cases, crushing the medicine can make it easier for the patients to accept and absorb, thereby improving the compliance and effectiveness of treatment. Regarding the above description, when using this device to crush and take granular medicine, first open the feed cover 15 at the upper end of the feed cylinder 14, and then place the medicine to be taken into the lower crushing chamber 13 through the feed cylinder 14 for crushing operations. After placing the required granular medicine into the lower crushing chamber 13, start the driving motor 22 to drive the driving shaft 23 at the output end of the driving motor 22 to rotate. The rotation of the driving shaft 23 drives the crushing shaft 31 to rotate, and the rotation of the crushing shaft 31 drives the crushing blades 32 to rotate. Thus, through the rotation of the crushing blades 32, the granular medicine located inside the lower crushing chamber 13 is crushed, realizing the crushing of the granular medicine, which is convenient for patients with difficulty swallowing or decreased digestive and absorption ability to take medicine, and is conducive to better receiving and absorbing the medicine for effective treatment;

[0051] The crushing blades 32 are conical, and the inside of the lower crushing chamber 13 is also conical and is in a state of being adapted to the shape of the spraying blades. Therefore, when the crushing blades 32 rotate to crush the granular medicine, the conical crushing blades 32 cooperate with the lower crushing chamber 13, enabling the granular medicine to receive more concentrated and uniform extrusion and shear forces during the crushing process. As the crushing blades 32 rotate, the medicine particles are gradually pushed towards the smaller end of the conical lower crushing chamber 13. During this process, the spacing between the particles continuously decreases, and the extrusion force received continuously increases, thereby being able to more effectively crush the medicine particles into smaller particles. Since the forces received by the medicine particles in the conical lower crushing chamber 13 are relatively uniform, and they experience a similar crushing process during the movement, the particle size distribution of the finally obtained crushed medicine particles is relatively narrow, that is, the particle size is more uniform. This is very important for the taking and absorption of the medicine because medicines with uniform particle size have a more consistent dissolution and absorption rate in the body, which helps to improve the efficacy and stability of the medicine. The adapted conical structure can make the crushing process smoother, reducing unnecessary energy loss. The gap between the crushing blades 32 and the lower crushing chamber 13 is uniform and gradually becomes smaller, enabling the medicine particles to make full use of the rotational energy of the crushing blades 32 during the crushing process without the situation of excessive collision or stagnation of the particles in the lower crushing chamber 13, thereby improving the energy utilization rate and reducing the energy consumption during the crushing process. The conical design makes the space of the lower crushing chamber 13 gradually become smaller, and the medicine particles are not easily piled up in the lower crushing chamber 13 during crushing, thus reducing the risk of blockage. Under the action of the conical structure, the continuity and stability of the crushing process are gradually ensured.

The capsule separation seat 61 is arranged on the inner side wall of the upper capsule separation cavity 34. The capsule separation motor 62 is arranged on the capsule separation seat 61. There are two capsule separation frames 67, and the two capsule separation frames 67 are symmetrically arranged on the two side walls of the upper capsule separation cavity 34.

The capsule separation main shaft 65 and the capsule separation driven shaft 66 are rotatably connected to the corresponding capsule separation frames 67. There are two capsule separation boxes 68, and the two capsule separation boxes 68 are symmetrically arranged. The two capsule separation boxes 68 are respectively sleeved on the capsule separation main shaft 65 and the capsule separation driven shaft 66. There are two capsule separation covers 69, and the two capsule separation covers 69 are respectively arranged on the corresponding capsule separation boxes 68 and are both magnetically connected.Both of the two capsule separation boxes 68 are provided with capsule separation grooves 681;

[0053] Due to the possible problems of insufficient strength and poor coordination in the throat muscles of patients with dysphagia, when swallowing a capsule, it is difficult to smoothly push the capsule into the esophagus like a normal person through the precise contraction and relaxation of the throat muscles. A capsule usually has a certain volume and shape, and is relatively smooth and hard. For patients with dysphagia, a larger capsule may be difficult to pass smoothly through the mouth and throat and is likely to get stuck at the bend of the throat or esophagus. Moreover, the smooth surface of the capsule also increases the difficulty of swallowing. Patients find it difficult to push it down through the frictional force of the throat muscles like swallowing textured food. Due to the previous bad experiences of dysphagia or choking, patients often have a fear psychology when facing capsule drugs. At present, patients with dysphagia take the drugs through external changes or by the anal route, etc. To sum up, at present, it is still quite difficult for patients with dysphagia to take capsule drugs. When a patient with dysphagia takes a capsule drug with this device, the appropriate taking method can be selected according to the patient's dysphagia condition. For patients with relatively mild dysphagia, warm water can be poured into the lower capsule mixing cavity 35, and then a straw with an inner diameter larger than that of the capsule drug can be taken, similar to a traditional milk tea straw. Then, the capsule to be taken is placed into the lower capsule mixing cavity 35 through the capsule placement hole 36. Next, the straw is inserted into the lower capsule mixing cavity 35 through the capsule placement hole 36 and extends into the lower capsule mixing cavity 35 to contact the warm water and is located at the upper position of the required height of the warm water. At this time, the patient inhales the warm water inside the lower capsule mixing cavity 35 through the straw. Affected by the suction force, the capsule will be inhaled into the straw and be inhaled synchronously with the warm water to achieve the taking of the capsule drug. This method can facilitate the patient to better control the water flow and the movement of the capsule, and inadvertently inhale and take the capsule drug by inhalation. This method helps swallowing, so it realizes the convenience for patients with relatively mild dysphagia to take capsule drugs;

[0054] When taking capsule drugs for patients with severe dysphagia, the capsule drug can be taken by separating the capsule drug and mixing it with warm water. First, open the fixed cover 39 so that the capsule placement groove 37 is exposed. Then, open the two capsule separation covers 69 so that the interiors of the two capsule separation boxes 68 are exposed, that is, the corresponding capsule separation grooves 681 are exposed. At this time, the capsule of the drug to be treated is placed into the corresponding capsule separation groove 681 in sequence. Then, cover and close the corresponding capsule separation boxes 68 with the two capsule separation covers 69 so that the capsules to be placed and taken in the two capsule separation boxes 68 are pressed by the two capsule separation covers 69. At this time, the capsule separation motor 62 runs to drive the rotation of the capsule separation main shaft 65 on the output end of the capsule separation motor 62. The rotation of the capsule separation main shaft 65 drives the rotation of the main gear 63. The rotation of the main gear 63 drives the rotation of the driven gear 64, thereby driving the rotation of the capsule separation driven shaft 66, so that the capsule separation main shaft 65 and the capsule separation driven shaft 66 rotate symmetrically and synchronously inward, thereby driving the symmetric inward movement of the capsule separation of the two closed capsule separation boxes 68. And through the symmetric inward movement of the two capsule separation boxes 68, the capsules in the two capsule separation boxes 68 are peeled off, and the capsules to be taken are separated. Finally, the drug inside the capsule falls from the upper capsule separation cavity 34 into the lower capsule mixing cavity 35 for storage. According to the mixing ratio of the capsule drug, the required warm water is added through the capsule placement hole 36, and the operation of the drive motor 22 drives the rotation of the driving wheel 51 on the output end of the drive motor 22. The rotation of the driving wheel 51 drives the rotation of the driven wheel 52 through the cooperation of the transmission belt 53. The rotation of the driven wheel 52 drives the rotation of the transmission shaft 54. The rotation of the transmission shaft 54 drives the rotation of the main bevel gear 55. The rotation of the main bevel gear 55 drives the rotation of the driven bevel gear 56. The rotation of the driven bevel gear 56 drives the rotation of the mixing shaft 42 on the mixing and stirring frame 41. The rotation of the mixing shaft 42 drives the rotation of the mixing disk 44. The rotation of the mixing disk 44 drives the mixing rod 45 to swing in the lower capsule mixing cavity 35. And the upper end of the mixing rod 45 is assisted in movement through the mixing block 43, realizing the full mixing of the drug separated from the capsule and the warm water in the lower capsule mixing cavity 35 by the mixing rod 45. Finally, rotate and remove the lower capsule mixing cavity 35 for the patient to take the drug, realizing that after the capsule of the device is separated, the liquid or suspension formed by mixing the drug and warm water is easier to pass through the pharynx and esophagus than the complete capsule. The patient does not need to overcome the difficulty of swallowing the capsule, reducing the risk of the capsule getting stuck in the pharynx or esophagus, thereby reducing the possibility of accidents such as choking and suffocation caused by swallowing. And after the drug is mixed with warm water, its surface area increases, and the contact area with the gastrointestinal mucosa also increases accordingly, which is conducive to the faster dissolution and absorption of the drug, so as to exert the drug effect faster. Especially for some drugs that need to take effect quickly, this method can make the drug enter the blood circulation faster.To achieve the therapeutic purpose, at the same time, for patients with dysphagia, it is easier to take medicine, which will reduce their fear and resistance to taking medicine, thereby improving the compliance of taking medicine. Patients are more willing to take medicine on time and in the right amount according to the doctor's advice, which helps the treatment and recovery of the disease. The capsule of this device separates and mixes the medicine. This method is not applicable to all capsule medicines, such as special dosage forms like enteric-coated capsules and sustained-release capsules. Opening the capsule will destroy its special drug release mechanism, which may cause the drug to be released at inappropriate sites, affecting the drug efficacy and even causing adverse reactions. Therefore, before using this method, it is necessary to consult a doctor or a pharmacist first to ensure the safety and effectiveness of medication.

[0055] Preferably, the stirring and mixing rod 45 is arranged in an L shape;

[0056] With the stirring and mixing rod 45 arranged in an L shape, the following effects can be achieved during the mixing and stirring of the medicine:

[0057] Enhance the mixing effect: The L-shaped stirring and mixing rod 45 can stir the substances in the capsule medicine storage cavity 33 in different directions. Its right-angle structure can make the stirring range wider. It can not only push and turn over the mixture of medicine and water in the horizontal direction, but also generate a force in the vertical direction, causing the substances at the bottom to be lifted and the substances at the top to be pressed down, promoting the full mixing of the upper and lower layers of substances, avoiding the situation of uneven local mixing, and thus improving the uniformity and efficiency of mixing.

[0058] Adapt to the structure of the storage cavity: The L-shaped design can better fit the shape and spatial layout of the capsule medicine storage cavity 33. Usually, the storage cavity is in the shape of a cuboid or a cylinder, etc. The L-shaped stirring rod can stir along the cavity wall and the bottom. Especially, it can also play a good stirring role at the corners and edges, effectively utilizing the space of the storage cavity, reducing the stirring dead corners, and ensuring that the capsule medicine and warm water in the whole storage cavity can be fully mixed.

[0059] Reduce drug residue: Since the L-shaped stirring and mixing rod 45 can cover the internal space of the storage cavity more comprehensively, during the stirring process, it can fully stir the mixture of medicine and water, making the medicine dissolve in water as much as possible, reducing the situation of the medicine adhering to the cavity wall and the bottom of the storage cavity, thereby reducing the drug residue amount, ensuring the accuracy of the drug dosage, and at the same time, it is also beneficial to keep the storage cavity clean and reduce the cleaning difficulty.

[0060] Preferably, both the lower crushing chamber 13 and the lower capsule mixing chamber 35 are lined with food-grade stainless steel and have smooth and corrosion-resistant inner walls;

[0061] Both the lower crushing chamber 13 and the lower capsule mixing chamber 35 are lined with food-grade stainless steel, and the inner walls are smooth and corrosion-resistant. The food-grade stainless steel meets strict hygiene standards, is non-toxic and harmless, and will not release harmful substances into the medicine or the mixed solution, ensuring the safety and purity of the medicine. It is especially suitable for the medicine preparation process that may be in direct contact with the human body and meets the requirements of relevant Good Manufacturing Practice for Pharmaceuticals (GMP).

[0062] Easy to clean and disinfect: The smooth inner wall is not easy to adsorb medicine particles, water stains or other impurities, reducing the breeding places of microorganisms such as bacteria and molds. This enables the chamber to be easily cleaned and disinfected after use, effectively preventing cross-contamination and ensuring that the chamber is in a sterile and clean state every time it is used, which is conducive to ensuring the stability and consistency of the medicine quality.

[0063] In this device, both the lower capsule mixing chamber 35 and the lower crushing chamber 13 can be removed by rotation. Therefore, the crushing blade 32 and the mixing and stirring rod are both in an exposed state, so as to facilitate the disinfection and cleaning of the lower capsule mixing chamber 35 and the lower crushing chamber 13 for repeated use. Moreover, the crushing blade 32 and the mixing and stirring rod are also easy to clean, ensuring the medicine quality and preventing cross-contamination. During the pharmaceutical process, the components of different medicines may be different. If the crushing blade 32 and the mixing and stirring rod are not easy to clean, the residual medicine may be mixed into other medicines during the next use, causing cross-contamination. The design that is easy to clean can effectively avoid this situation, ensuring that the purity and quality of each medicine are not affected, and also avoiding the deterioration of the medicine. Residual medicine is easy to adsorb moisture and impurities in the air, breed bacteria or undergo chemical reactions, resulting in the deterioration of the medicine. Easy cleaning can timely remove these residual medicines, reduce the risk of medicine deterioration, ensure the effectiveness and safety of the medicine, and at the same time shorten the cleaning time. The easy-to-clean crushing blade 32 and mixing and stirring rod can quickly complete the cleaning work during the production interval, reducing the equipment downtime. This can improve the utilization rate of the equipment, make the production process smoother, and contribute to improving the overall production efficiency.
