Description

Technical Field

[0001] The present invention relates to the technical field of drug administration, and in particular to a drug administration device for internal medicine. Background Art

[0002] Drug delivery devices for internal medicine are an indispensable and important tool in modern medicine. They are mainly used to achieve accurate drug delivery and efficient treatment. Internal medicine usually involves the diagnosis and treatment of various visceral diseases, while drug delivery devices for internal medicine focus on different routes of administration to meet the individual needs of patients. There are many types of drug delivery devices for internal medicine, including but not limited to syringes, infusion pumps, drug atomizers, and oral drug delivery devices. Oral administration is a common and effective way of drug delivery. However, in order to improve the bioavailability and therapeutic effect of drugs, many drugs need to be crushed before oral administration. The necessity of this process is mainly reflected in the following aspects. First, the volume and form of the drug have a direct impact on its absorption rate. Most solid drugs exist in the form of tablets with a large particle size, which leads to a slow dissolution rate in the digestive tract. By crushing the drug, it can be converted into a microparticle state, significantly increasing the surface area of ​​the drug, thereby accelerating the dissolution and absorption of the drug in the gastrointestinal tract, and thus improving its bioavailability. For some special populations, such as the elderly, children, or patients with dysphagia, crushing the drug can also improve their medication experience. For these patients, whole tablets may be difficult to swallow, while crushed drugs can be mixed with liquids or food for easy administration, ensuring that patients can receive treatment on time and in the right amount. Reasonable selection of drug administration routes and device types can develop personalized treatment plans based on different diseases, the patient's physical condition and age, and other factors. With the advancement of technology, the intelligence and automation of internal medicine drug delivery devices are developing rapidly.

[0003] Some existing patients may encounter some tablet medicines during the treatment process. Because it is difficult for them to take the medicines by themselves, they need to crush the medicines first so that they can be taken with water. However, most of the current crushing devices are made on-site, which leads to a limited degree of crushing. In addition, the medicines are easily lost during the crushing process, so that the standard dosage cannot be reached. Therefore, this problem needs to be solved. Summary of the invention

When the medicine delivery port 501 completes the medicine delivery, the reduction motor 6 will reverse accordingly, and a limiting groove 605 is provided at the bottom of the first rotating shaft 601, and the limiting groove 605 is matched with the docking disk 606 through the limiting column 604, so that when the reduction motor 6 rotates, the docking disk 606 will also rotate, and a third ratchet pawl 607 is installed on the surface of the docking disk 606, and the third ratchet pawl 607 cooperates with the third ratchet groove 703 on the top of the fixed disk 701, so that When the reduction motor 6 drives the first rotating shaft 601 to reverse, the third pawl 607 will drive the fixed plate 701 to rotate through the third ratchet groove 703, and the second rotating shaft 702 is installed at the bottom of the fixed plate 701, and the surface of the second rotating shaft 702 is provided with a rolling plate 8, and the rolling plate 8 is matched with the second rotating shaft 702 through the constraint groove 802, so that when the fixed plate 701 drives the second rotating shaft 702 to rotate, the rolling plate 8 will also rotate synchronously, and two adjusting blocks 801 are symmetrically installed on the surface of the rolling plate 8, and the first adjusting groove 405, the second adjusting groove 406, and the third adjusting groove 407 are opened inside the rolling cylinder 4, and the adjusting block 801 is initially installed inside the first adjusting groove 405, and is in the highest position, so that To ensure that the tablets can enter the interior of the grinding cylinder 4, second adjusting grooves 406 are opened on both sides of the first adjusting groove 405. When the second rotating shaft 702 drives the grinding disc 8 to rotate, the adjusting block 801 will enter one of the second adjusting grooves 406, so as to ensure that the grinding disc 8 can move downward during the rotation. Because the grinding disc 8 moves downward while rotating, the tablets inside the grinding cylinder 4 can be crushed, and the downward movement height of the grinding disc 8 is set, so during its operation, it can ensure that the tablets can be crushed more evenly. After the tablets are crushed, the grinding disc 8 will be reset under the action of another second adjusting groove 406. A connecting rod 803 is also installed inside the grinding disc 8.A knocking rod 805 is installed at the bottom of the connecting rod 803, and a gear 806 is installed on the top of the connecting rod 803. The gear 806 cooperates with the toothed roller 705 inside the grinding cylinder 4, so that when the second rotating shaft 702 drives the grinding disk 8 to rotate, the toothed roller 705 can drive the knocking rod 805 to rotate through the gear 806. Because the knocking rod 805 cooperates with the grinding disk 8, when the knocking rod 805 rotates, the grinding disk 8 can be knocked to avoid the phenomenon of residual powder. In the process of resetting the grinding disk 8, the electric push rod 901 will start accordingly. A lifting ring 9 is installed at the bottom of the electric push rod 901, and the lifting ring 9 is connected to the connecting arm 902. It cooperates with the baffle 903 at the bottom of the rolling cylinder 4. Because the baffle 903 slides on the bottom of the rolling cylinder 4, when the electric push rod 901 drives the lifting ring 9 to move upward, the lifting ring 9 will drive the baffle 903 to move through the connecting arm 902, so that it can open the bottom of the rolling cylinder 4. As the baffle 903 continues to open, the powder on the top of the baffle 903 will also fall to the bottom of the shell 1. Before the baffle 903 is opened, the second liquid delivery pumps 201 on both sides of the shell 1 will be started to transport the liquid inside the liquid storage tank 2 to the bottom of the shell 1. A heating block is installed inside the liquid storage tank 2, which can be turned on or off according to needs. A stirring rod 905 is also installed at the bottom of the lifting ring 9. A fourth rotating block 906 is installed on the top of the stirring rod 905. The stirring rod 905 is initially at the bottom of the second rotating shaft 702. A rotating shaft 707 is installed inside the second rotating shaft 702. As the lifting ring 9 continues to move upward, the stirring rod 905 will contact and squeeze the rotating shaft 707, so that it can move upward. As the rotating shaft 707 continues to move upward, it will squeeze the docking plate 606, so that it also moves upward synchronously. When the docking plate 606 moves up to the right position, the third pawl 607 will no longer cooperate with the fixed plate 701. Two first rotating blocks 610 are installed at the bottom of the docking plate 606, and the first rotating block 610 is in contact with the top of the rotating shaft 707. The second rotating block 708 cooperates with the first rotating shaft 601, so that when the reduction motor 6 drives the first rotating shaft 601 to rotate, the rotating shaft 707 will rotate synchronously. Two third rotating blocks 709 are installed at the bottom of the rotating shaft 707, and the two third rotating blocks 709 cooperate with the fourth rotating block 906 at the top of the stirring rod 905, so as to ensure that after the reduction motor 6 is started again, the stirring rod 905 can stir the powder, so that it can be more quickly integrated with water. The control valve 101 and the first liquid delivery pump 102 are respectively installed at the bottom of the shell 1. When the powder is fully integrated with the water, the control valve 101 will open, and then the liquid medicine will be delivered to the patient through the first liquid delivery pump 102.
