Description
Technical Field
[0001] The present invention particularly relates to a timed and quantitative drug delivery device. Background Art
[0002] In the field of long-term treatment of chronic diseases and independent medication management for the elderly, timed and quantitative drug delivery devices must simultaneously meet core requirements such as timing control accuracy, dose release reliability, and medication compliance monitoring.
[0003] Currently, with the shrinking of family structures, changes in housing and attitudes, the aging of people living alone is increasing. Their ability to cope with emergencies is declining, and without care, accidents are more likely to happen, difficult to detect, and lead to serious consequences. As people living alone age, their vision and memory gradually decline. At the same time, most elderly people need to take a certain amount of medication on time. When they are alone, they cannot accurately control the amount and timing of medication, which can easily lead to danger. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the technical problem to be solved by the present invention is to provide a timed and quantitative drug delivery device that can perform quantitative and timed drug delivery, thereby improving the accuracy and safety of medication.
[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions: a timed and quantitative drug delivery device, comprising: Support frame; A vertically arranged drug temporary storage channel with through openings at the top and bottom; Dosage unit containers, wherein there are multiple dosage unit containers, and the multiple dosage unit containers are stacked from bottom to top in the drug temporary storage channel, and the dosage unit containers are used to store drugs that need to be taken in a single dose; a timed dispensing mechanism, disposed on the support frame and connected to the drug temporary storage channel, capable of periodically and individually dispensing the dosage unit containers in the drug temporary storage channel from the bottom of the drug temporary storage channel; a receiving platform, provided on the supporting frame, for receiving a single dosage unit container dispensed from the timed dispensing mechanism; and A status feedback module is integrated with the receiving platform and configured to trigger an alarm signal in response to the insertion of the dosage unit container.
[0006] Furthermore, the timed material dispensing mechanism includes a rotating disk, a rotating drive component and a blocking structure. The rotating disk is arranged close to the bottom end surface of the drug temporary storage channel. The rotating drive component is used to drive the rotating disk to rotate one circle every 24 hours. The rotating disk is circumferentially spaced with 24 vertically through-holes. The aperture of the leakage hole is larger than the outer diameter of the dosage unit container. When the rotating disk rotates, the leakage holes can pass through the bottom end of the drug temporary storage channel in sequence. Each of the leakage holes is provided with a blocking structure that can be opened.
[0007] Furthermore, 24 radially extending guide grooves are circumferentially spaced apart on the receiving platform, each of the guide grooves is connected to the corresponding medicine leakage hole, and the blocking structure includes a slider, which can be slidably mounted in the guide groove, and the slider can be pushed to block the medicine leakage hole.
[0008] Furthermore, the upper surface of the slider is flush with the upper surface of the rotating disk.
[0009] Furthermore, the blocking structure further includes a screw, which is rotatably inserted into the guide groove along the radial direction of the rotating disk and is rotatably connected to the slider, and the screw is threadedly connected to the rotating disk.
[0010] Furthermore, it also includes a medicine taking record mechanism, which is connected to the receiving platform and is used to record the number of times the dosage unit container is taken out from the receiving platform.
[0011] Furthermore, the medicine taking and recording mechanism includes a uniform speed drive structure, a recording tape, a scratch pen and a transmission assembly. The recording tape is vertically installed on the support frame. The uniform speed drive structure is used to drive the recording tape to slide vertically. The scratch pen is connected to the receiving platform through the transmission assembly. The receiving platform is arranged on the support frame so as to be movable up and down through an elastic support member, and the supporting force of the elastic support member is less than the weight of a single dosage unit container. The scratch pen is connected to the receiving platform through the transmission assembly. Every time the receiving platform rises, the scratch pen can scratch the recording tape once.
[0012] Furthermore, the transmission assembly includes a transmission gear and a plurality of toggle teeth. The transmission gear is rotatably arranged on the support frame through a rotating shaft. The plurality of toggle teeth are vertically spaced on the side wall of the receiving platform. The toggle teeth can engage with the transmission gear and drive the transmission gear to rotate one circle each time the receiving platform rises. The scratch pen is fixed on the moving gear. During the process of the rotating shaft rotating one circle, the scratch pen scratches the recording tape once.
[0013] Furthermore, the shifting tooth includes a shifting rod and a stopper, the shifting rod is rotatably hinged on the receiving platform, and the stopper is fixed on the receiving platform and is tightly arranged with the lower surface of the shifting rod.

[0015] Beneficial effects of the present invention: When using the timed quantitative drug delivery device, a caregiver can package multiple daily doses of medication into dosage unit containers. These containers are then stacked in a sequence from bottom to top within the medication storage channel. The timed dispensing mechanism then periodically releases the bottom container, causing the dosage unit containers to fall onto the receiving platform, triggering the status feedback module. The status feedback module then sounds an alarm until the patient removes the medication.
[0016] By using the above-mentioned timed quantitative drug delivery device, the drugs can be taken in a quantitative manner through pre-distribution. At the same time, the vertical stacking structure ensures that the drugs are accurately arranged in the order of taking; through the timed release and double reminder mechanism, the risk of missing a dose can be significantly reduced.

[0019] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0020] See Figures 1 to 5 The present invention provides a timed and quantitative drug delivery device, including a support frame 100, a vertically arranged drug temporary storage channel 200, a dosage unit container 300, a timed material distribution mechanism 400, a receiving platform 500 and a state feedback module 600.
[0021] Specifically, the medication temporary storage channel 200 is vertically arranged with openings at its top and bottom. Multiple dosage unit containers 300 are stacked from bottom to top within the medication temporary storage channel 200 to store medication for a single dose.
[0022] The timed dispensing mechanism 400 is mounted on the support frame 100 and connected to the temporary drug storage channel 200. It periodically and individually dispenses the dosage unit containers 300 within the temporary drug storage channel 200 from the bottom of the channel 200. The periodicity can be four times, three times, two times, or once daily. For example, if the timed dispensing mechanism is set to four times daily, the dispensing mechanism can be set to release the dosage unit containers 300 at 8:00, 12:00, 16:00, and 20:00 respectively; if the timed dispensing mechanism is set to three times daily, the dispensing mechanism can be set to release the dosage unit containers 300 at 8:00, 13:00, and 18:00 respectively; if the timed dispensing mechanism is set to two times daily, the dispensing mechanism can be set to release the dosage unit containers 300 at 8:00 and 18:00 respectively; and if the timed dispensing mechanism is set to release the dosage unit containers 300 at 6:00, the dispensing mechanism can be ...8:00 and 18:00 respectively.
[0023] The receiving platform 500 is disposed on the support frame 100 and is used to receive individual dosage unit containers 300 dispensed from the timed dispensing mechanism 400. A status feedback module 600 is integrated into the receiving platform 500 and configured to trigger an alarm signal in response to the placement of a dosage unit container 300. The alarm signal can be presented in the form of sound, light, or color.
[0024] During use, the caregiver can pack multiple daily doses of medication into dosage unit containers 300, then stack the dosage unit containers 300 from bottom to top in the medication temporary storage channel 200. When the timed dispensing mechanism 400 periodically releases the bottom container, the dosage unit containers 300 fall onto the receiving platform 500, triggering the status feedback module 600. The status feedback module 600 issues an alarm until the patient removes the medication and the alarm stops.
[0025] By using the above-mentioned timed quantitative drug delivery device, the drugs can be taken in a quantitative manner through pre-distribution. At the same time, the vertical stacking structure ensures that the drugs are accurately arranged in the order of taking; through the timed release and double reminder mechanism, the risk of missing a dose can be significantly reduced.
[0026] In this embodiment, the timed dispensing mechanism 400 includes a rotating disk 410, a rotary drive member 420, and a blocking structure 430. The rotating disk 410 is positioned in close proximity to the bottom end surface of the drug storage channel 200. The rotary drive member 420 is configured to drive the rotating disk 410 to rotate once every 24 hours. In a specific implementation, the rotary drive member 420 can be a conventional rotary motor.
[0027] Twenty-four leakage holes 411 extending vertically therethrough are circumferentially spaced apart on the rotating disk 410. The diameter of the leakage holes 411 is larger than the outer diameter of the dosage unit container 300. When the rotating disk 410 rotates, the leakage holes 411 can sequentially pass through the bottom end of the drug temporary storage channel 200. An openable blocking structure 430 is provided in each leakage hole 411.
[0028] During use, the blocking structure 430 at the existing position is opened according to the number of times the drug needs to be taken per day. For example, when the drug needs to be taken three times, the blocking structure 430 at the 1st, 6th, and 11th positions below the drug storage channel 200 may need to be opened. At 08:00 on the first day, the motor starts to drive the rotating disk 410 to rotate. When the first drug leakage hole 411 is aligned with the bottom of the temporary storage channel, the bottom container falls to the receiving platform 500 due to gravity, and the status feedback module 600 sends a warning signal to remind the patient to take the drug. Subsequently, when passing the 6th drug leakage hole, a second release is performed, and when passing the 11th drug leakage hole, a third release is performed. In this way, by setting a 24-hole design, the daily medication cycle is accurately corresponded, so as to achieve timed and quantitative drug administration.
[0029] In this embodiment, 24 radially extending guide grooves 412 are circumferentially spaced apart on the receiving platform 500, and each guide groove 412 is connected to a corresponding drug leakage hole 411. The blocking structure 430 includes a slider 431. The slider 431 is slidably mounted within the guide groove 412. When the slider 431 is pushed, the slider 431 can be blocked within the drug leakage hole 411. In the normal state, the slider 431 is blocked within the drug leakage hole 411. When medication is required, the slider 431 is slid within the corresponding guide groove 412 to unblock the drug leakage hole 411.
[0030] In a specific implementation, to prevent the slider 431 from sliding freely during the rotation of the rotating disk 410, the blocking structure 430 further includes a screw 432. The screw 432 is rotatably inserted into the guide groove 412 along the radial direction of the rotating disk 410 and is rotatably connected to the slider 431. The screw 432 is threadedly connected to the rotating disk 410. Rotating the screw 432 drives the slider 431 to slide while preventing the slider 431 from moving freely.
[0031] As a preferred embodiment, during specific implementation, the upper surface of the slider 431 can be flush with the upper surface of the rotating disk 410 to avoid interference and facilitate the rotation of the rotating disk 410.
[0032] As another preferred embodiment, the timed and quantitative drug delivery device further includes a medication removal recording mechanism 700, which is connected to the receiving platform 500 and is configured to record the number of times the dosage unit container 300 is removed from the receiving platform 500. The medication removal recording mechanism 700 can intuitively detect when a patient or guardian has missed medication, allowing for appropriate measures to be taken. For example, if the medication removal recording mechanism 700 detects that a patient forgot to take medication at noon, the patient can be reminded that this is a common practice, thereby preventing the same situation from occurring later.
[0033] In this embodiment, the medication recording mechanism 700 includes a uniform speed drive structure 710, a recording tape 720, a stylus 730, and a transmission assembly 740. The recording tape 720 is vertically mounted on a support frame. The uniform speed drive structure 710 is used to drive the recording tape 720 to slide vertically. In a specific implementation, the uniform speed drive structure 710 can be a clockwork mechanism; or a winder capable of automatic winding can be provided at both ends, such that the winder can automatically unwind the wire when subjected to an external pulling force.
[0034] The scratch pen 730 is connected to the receiving platform 500 via a transmission assembly 740. The receiving platform 500 is mounted on the support frame 100 so that it can move up and down via an elastic support member 510. The support force of the elastic support member 510 is less than the weight of a single dosage unit container 300. The scratch pen 730 is connected to the receiving platform 500 via the transmission assembly 740. Each time the receiving platform 500 rises, the scratch pen 730 can scratch the recording tape 720 once.
[0035] When the dosage unit container 300 falls onto the receiving platform 500, the receiving platform 500 is pressed down. After each time the patient manually takes the medicine, the receiving platform 500 rises, thereby converting the lifting motion into the displacement of the scratch pen 730 through the transmission assembly 740, forming a scratch mark on the moving recording tape 720.
[0036] In this way, the correspondence between time and number of times of taking medicine can be visualized directly, thereby accurately reflecting the patient's medication situation.
[0037] In this embodiment, the transmission assembly 740 includes a transmission gear 741 and a plurality of toggle teeth 742. The transmission gear 741 is rotatably arranged on the support frame 100 through a rotating shaft. The plurality of toggle teeth 742 are vertically spaced on the side wall of the receiving platform 500. The toggle teeth 742 can engage with the transmission gear 741 and drive the transmission gear 741 to rotate one circle each time the receiving platform 500 rises. The scratch pen 730 is fixed on the transmission gear 741. During the process of the rotating shaft rotating one circle, the scratch pen 730 scratches the recording tape 720 once.
[0038] Specifically, the shifting tooth 742 includes a shifting rod 7421 and a stopper 7422 . The shifting rod 7421 is rotatably hinged on the receiving platform 500 . The stopper 7422 is fixed on the receiving platform 500 and is tightly attached to the lower surface of the shifting rod 7421 .
[0039] Each time medication is removed from the platform, the platform rises, driving the shifting gear 742 upward, which in turn rotates the gear one revolution. As the streaking pen 730 rotates with the shifting gear 742, it comes into contact with the recording tape 720, driving the streaking pen 730 to complete one scratching motion. When the platform descends, the shifting lever 7421 stops shifting, and the transmission gear 741 stops rotating. To prevent the gear from rotating during the platform's descent, a one-way ratchet mechanism is designed to prevent reverse rotation.
[0040] In this embodiment, the state feedback module 600 includes a pressure-sensitive trigger device configured to activate an audible and visual alarm signal upon detecting the application of a load. The pressure sensor of the pressure-sensitive trigger device can utilize a thin-film piezoelectric element, with a detection threshold set to 0.5-1.0N (corresponding to 60-140% of the container weight). When the pressure exceeds the threshold for three consecutive seconds, an LED flash (5Hz) and an 85dB buzzer alarm are triggered. This allows for dynamic threshold adaptation to containers of varying drug weights, thereby avoiding delayed triggering and preventing false alarms caused by accidental contact.
[0041] The overall workflow of the above-mentioned timed quantitative drug delivery device is as follows: 1. Medicine loading stage: put multiple pre-filled dosage unit containers 200 into the medicine temporary storage channel 300 in the order of taking medicine; and open the relevant medicine leakage holes according to the number of times of taking medicine. 2. Timed release: The rotating disk 410 rotates 15° every hour and releases the container at the corresponding hole position; 3. Medication Reminder: The container touches the receiving platform 500 to trigger an audible and visual alarm, and the patient takes the medicine 4. Record mark: Each time the medicine is taken, the platform resets and drives the scratch pen 730 to generate a timestamp; The use of this timed and quantitative drug delivery device achieves triple guarantees of drug delivery timing, dosage accuracy and operation traceability. It is particularly suitable for the care scenarios of chronic disease patients who need to strictly follow the medication plan.
