Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and particularly to a drug delivery device for clinical internal medicine. Background Art
[0002] The core of oncology internal medicine treatment lies in achieving precise killing of malignant tumor cells through systematic drug intervention. However, existing drug delivery devices still have significant technical bottlenecks in aspects such as drug delivery efficiency, treatment accuracy, and individual regulation ability. Traditional intravenous infusion devices mostly adopt the principle of passive diffusion and cannot achieve intelligent response release of drugs according to the dynamic changes of the tumor microenvironment (such as hypoxia, pH gradient, enzyme expression differences, etc.), resulting in an effective enrichment rate of less than 30% of the drug at the lesion site and simultaneously causing systemic toxic reactions. In addition, for the scenario of multi-drug combination, the current drug delivery system lacks a timing control module and is difficult to achieve the coordinated release of chemotherapeutic drugs, targeted agents, and immunomodulators, severely weakening the theoretical synergistic effect space of combination therapies.
[0003] According to the Chinese patent with the patent number: CN118750681A, a quantitative drug delivery device for oncology internal medicine is disclosed, including: a quantitative drug delivery box and a quantitative infusion bottle adapted to the quantitative drug delivery box; the quantitative drug delivery box includes a drug control module, a drug storage module provided at the bottom of the drug control module, four mechanical telescopic columns provided at the bottom corners of the drug storage module, and a bottom plate provided at the bottom of the mechanical telescopic columns; wherein, a display area and a control area for controlling the drug amount and infusion speed are provided on the front of the drug control module; the bottom of the quantitative infusion bottle is set as an arc structure, a capacity scale line is provided on the bottle body of the quantitative infusion bottle, the quantitative infusion bottle includes an infusion bottle body and an infusion tube provided at the bottom of the infusion bottle body, and an infusion pump for controlling the liquid flow rate is provided on the infusion tube and is wirelessly connected to the drug control module. The present invention can achieve intelligent matching of multiple liquid medicines and precise control of the dosage according to the actual condition, so that the treatment effect reaches the best.

The rotating motor 2 is fixed to the lower side of the loading box 1, the transmission rod 3 is rotatably connected inside the loading box 1, the transmission rod 3 is power-connected to the rotating motor 2, the electric adjusting rod 4 is fixed to the upper side of the transmission rod 3, the grinding roller 5 is rotatably connected to the electric adjusting rod 4, a limiting sleeve 7 is fixed to the lower side of the grinding roller 5, a transmission block is fixed inside the limiting sleeve 7, a limiting block 8 is fixed to the electric adjusting rod 4, and the limiting block 8 is in transmission with the transmission block of the limiting sleeve 7. The grinding inner wall 6 is fixed to the inner wall of the loading box 1, and the cross-section of the grinding inner wall 6 is similar to that of the grinding roller 5. The user puts the drug into the loading box 1. First, the user controls the telescopic length of the electric adjusting rod 4 through the control panel 17 according to the specific condition of the patient, so as to control the distance between the grinding roller 5 and the grinding inner wall 6, and thus can grind out drug powders with different particle sizes.
[0021] In one aspect of this embodiment, a motor bracket 9 is fixed to the lower side of the rotating motor 2, the motor bracket 9 is fixed to the lower side of the loading box 1, a heating coil 13 is fixed to the bottom of the loading box 1, a viewing window is opened on the front of the loading box 1, a support plate 16 is fixed to the bottom of the loading box 1, a control panel 17 is fixed to the side of the loading box 1, and the control panel 17 is composed of an LED display screen and control buttons. The heating coil 13 at the bottom of the loading box 1 can control the temperature of the drug powder according to the condition of the patient, so as to facilitate the user's absorption more conveniently.
[0022] In one aspect of this embodiment, a stirring rod 10 is fixed on the transmission rod 3. A feeding plate 11 is fixed on the transmission rod 3 near the bottom of the loading box body 1. A discharge valve 12 is fixed on the side of the loading box body 1. A spring telescopic rod 14 is fixed at the end of the stirring rod 10, and a rubber ball 15 is fixed at the end of the spring telescopic rod 14. The rotation motor 2 drives the stirring rod 10 to rotate, which can fully mix different drug powders. At the same time, the user changes the rotation speed of the rotation motor 2, thereby changing the centrifugal force of the spring telescopic rod 14, so that the rubber ball 15 can strike the inner wall of the loading box body 1, thereby knocking down the residual drug powder on the inner wall of the loading box body 1.
[0023] In one aspect of this embodiment, the cross-section of the grinding roller 5 is composed of two isosceles trapezoids. Grinding particles 24 are fixed on the grinding inner wall 6. A sliding track 25 is opened on the grinding inner wall 6. Sliding rods 18 are fixed on both sides of the grinding roller 5. The sliding rod 18 is composed of a sliding bracket and a rotating ball. The sliding track 25 is rotationally connected to the sliding rod 18. The grinding particles 24 can increase the friction force during the grinding process and improve the grinding efficiency.
[0024] In one aspect of this embodiment, a weighing device 19 is fixed on the loading box body 1. The grinding roller 5 is rotationally connected to the bottom plate of the weighing device 19. A rotating rod 20 is rotationally connected to the weighing device 19. The rotating rod 20 is power-connected to the grinding roller 5. A rotating plate 21 is fixed on the rotating rod 20. A storage tank 22 is opened in the weighing device 19. A moving slide rail is opened in the storage tank 22. A pull-out plate 23 is connected to the moving slide of the storage tank 22. The user sequentially places the drugs on the weighing device 19 and inputs the corresponding weight through the control panel 17. The grinding roller 5 drives the rotating plate 21 on the rotating rod 20 to rotate, thereby transporting the drugs to the pull-out plate 23 of the storage tank 22. By comparing the difference before and after the weighing device 19, the input weight of the drugs can be accurately measured. After reaching the specified weight, the rotating plate 21 rotates in the opposite direction. The user takes out the drugs and then puts in the remaining drugs. After weighing, the user removes the pull-out plate 23 and inputs the drugs into the loading box body 1.
[0025] The working principle of the present invention is as follows: During the use of the present invention, first, the user controls the telescopic length of the electric adjusting rod 4 through the control panel 17 according to the specific condition of the patient, so as to control the distance between the grinding roller 5 and the grinding inner wall 6. Then, the drugs are placed on the weighing device 19 in sequence, and the corresponding weight is input through the control panel 17. Then, the rotating motor 2 drives the electric adjusting rod 4 on the transmission rod 3 to rotate. The limiting block 8 on the electric adjusting rod 4 is in transmission with the transmission block of the limiting sleeve 7, so that the grinding roller 5 drives the rotating plate 21 on the rotating rod 20 to rotate, so as to transport the drugs to the pull-out plate 23 of the storage tank 22. By comparing the difference before and after the weighing device 19, the input weight of the drugs can be accurately measured. After reaching the specified weight, the rotating plate 21 rotates in the opposite direction. The user takes out the drugs and then puts in the remaining drugs. After weighing is completed, the user removes the pull-out plate 23 to input the drugs into the loading box 1. The grinding roller 5 continues to rotate and grinds the drugs in cooperation with the grinding particles 24 on the grinding inner wall 6. The drugs that meet the particle size fall to the bottom of the loading box 1. After grinding is completed, at this time, the heating coil 13 is started to control the temperature of the drug particles. At the same time, the rotating motor 2 rotates reciprocally, so that the limiting block 8 does not contact the transmission block of the limiting sleeve 7, reducing the power output of the rotating motor 2, and fully stirring the medicinal powder. After stirring is completed, the discharge valve 12 is opened, and the medicinal powder is discharged under the action of the feeding plate 11. And the instantaneous speed of the rotating motor 2 is changed, changing the centrifugal force of the spring telescopic rod 14, so that the spring telescopic rod 14 can be quickly telescoped, so that the rubber ball 15 hits the inner wall of the loading box 1, so as to knock down the residual medicinal powder on the inner wall of the loading box 1 and complete the operation of discharging the medicinal powder.
