Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a drug feeding device with a quantitative drug feeding function. Background Technology
[0002] In the field of medical care, whether for infants, children, or patients with certain special diseases (such as elderly people with difficulty swallowing, patients with neurological diseases who need precise control of medication dosage), accurate and quantitative medication is crucial. Therefore, when performing accurate and quantitative medication, it is necessary to use a medication feeding device with quantitative function. However, existing medication feeding devices with quantitative function still have certain defects in use.
[0003] For example, the quantitative drug feeder proposed in application number CN202421118510.4 relates to the field of medical drug feeder technology. The device includes a piston tube, and a push-pull assembly is slidably connected inside the piston tube, including a rotating rod, a threaded sleeve, a push rod, a palm plate, a fixing block, a sliding plate, and a piston. The bottom of the rotating rod is threadedly connected to the threaded sleeve, the bottom of the threaded sleeve is connected to the push rod, the top of the rotating rod is connected to the palm plate, the bottom of the palm plate is symmetrically provided with fixing blocks, the outer surface of the threaded sleeve is symmetrically provided with sliding plates, and the bottom of the push rod is connected to the piston. In actual use, the quantitative drug feeder adjusts the exposed length of the rotating rod by rotating the rotating rod, thereby limiting the pushing distance to achieve quantitative drug feeding. However, the device uses a rotating locking block to engage with the locking slot. But this locking method relies only on the direct friction and misalignment between the two to achieve the combined connection, which has unstable stability. At the same time, when docking the diversion assembly with the installation assembly, there are also problems of unstable connection and easy detachment.
[0004] Therefore, we propose a drug delivery device with quantitative drug delivery function to solve the problems mentioned above. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Please see Figure 1-5 This utility model provides a technical solution: a feeding device with quantitative feeding function, including an outer protective tube 1 and a drug storage tube 12. The bottom end of the outer protective tube 1 is fixedly connected to a docking block 2. A vent hole 3 is opened at the top corner of the docking block 2. A rotating quantitative mechanism is installed inside the outer protective tube 1. The rotating quantitative mechanism includes a threaded column 4 that passes through the middle of the docking block 2. A pressing plate 5 is fixedly connected to the bottom end of the threaded column 4. An adjusting tube 6 is sleeved on the outer ring of the threaded column 4. The adjusting tube 6 is threadedly connected to the threaded column 4. A scale 7 is opened on the outer ring of the adjusting tube 6. The scale 7 is spirally distributed on the outer ring of the adjusting tube 6. A knob 8 is fixedly installed on the top of the adjusting tube 6. A button 9 is fixedly installed on the top of the knob 8. The rotating quantitative mechanism also includes a pointer 10 fixedly installed on the inner side of the top of the outer protective tube 1. Handles 11 are symmetrically installed on the outer ring of the outer protective tube 1. A piston 14 is slidably arranged inside the drug storage tube 12. A transparent observation window 13 for observing the amount of medicine is opened at equal angles on the outer side of the drug storage tube 12.
[0036] The design of the above structure allows the regulating tube 6 to rotate synchronously by rotating the knob 8 after the medicine storage tube 12 is fixedly connected to the outer protective tube 1. The regulating tube 6 then spirals upward on its outer ring through the connection with the threaded column 4, driving the scale 7 to spiral upward until the pointer 10 corresponds to the desired feeding amount scale 7 and stops rotating. Then, by pressing the button 9, the regulating tube 6, the threaded column 4, and the pressing plate 5 can be driven to descend synchronously. During the descent, the piston 14 is squeezed, so that the liquid medicine inside the medicine storage tube 12 can be squeezed by the piston 14 and discharged through the feeding seat 22, thereby realizing quantitative feeding. The handle 11 is designed to facilitate easy gripping of the feeding device and improve the use effect. The transparent observation window 13 allows monitoring of the remaining liquid medicine inside the medicine storage tube 12 to avoid insufficient medicine.
[0037] A docking positioning mechanism is symmetrically connected between the medicine storage tube 12 and the outer protective tube 1. The docking positioning mechanism includes a positioning seat 15 symmetrically installed on the outer side of the bottom of the outer protective tube 1. A limit rod 16 is fixedly installed on the outer side of the positioning seat 15. A baffle 17 is fixedly installed on the outer end of the limit rod 16. A movable plate 18 is sleeved on the outer ring of the positioning seat 15. A locking block 20 is fixedly installed on the inner side of the bottom of the movable plate 18. The docking positioning mechanism also includes a spring 19 sleeved on the outer ring of the limit rod 16 between the movable plate 18 and the baffle 17. The movable plate 18 and the baffle 17 form a telescopic structure through the spring 19. A locking groove 21 is symmetrically opened on the top of the medicine storage tube 12. The locking block 20 is movably locked and connected to the locking groove 21.
[0038] The design of the above structure allows the movable plate 18 to slide in a limited manner on the outer ring of the limiting rod 16 by pulling the movable plate 18 outward and pushing the movable plate 18 inward to reset it by the spring 19. This allows the bottom locking block 20 to engage and disengage from the locking groove 21. When the two separate, the limiting positioning of the medicine storage tube 12 can be released and the medicine storage tube 12 can be replaced. Then, when installing the medicine storage tube 12, the locking mechanism can be used to achieve stable positioning. The positioning seat 15 can stably install the limiting rod 16, while the baffle 17 can effectively support the extension and retraction of the spring 19. After the medicine storage tube 12 is disassembled, the rotation of the pressing plate 5 can drive the threaded column 4 to spirally rise inside the adjusting tube 6 to achieve reset.
[0039] A feeding seat 22 is fixedly embedded at the bottom end of the medicine storage tube 12. A movable protective mechanism is provided around the outer ring of the feeding seat 22. The movable protective mechanism includes a protective sleeve 23 that is movably fitted around the outer ring of the feeding seat 22. The protective sleeve 23 provides full protection for the feeding seat 22. A sealing plug 24 is fixedly installed at the bottom inner side of the protective sleeve 23. A threaded seat 25 is fixedly connected to the top of the protective sleeve 23. The size of the sealing plug 24 matches the size of the bottom opening of the feeding seat 22. The threaded seat 25 is threadedly connected to the feeding seat 22.
[0040] The design of the above structure allows the threaded seat 25 to be separated from the feeding seat 22 by rotating it when using the feeding device, thereby allowing the sheath 23 and the sealing plug 24 to be disassembled for quantitative feeding after disassembly. After stopping the feeding, the sheath 23 is placed on the outside of the feeding seat 22, and the threaded seat 25 is threadedly connected to the feeding seat 22 by rotating it in the opposite direction. This allows the sheath 23 to provide full protection for the feeding seat 22, and the sealing plug 24 to effectively seal the bottom opening of the feeding seat 22.
[0041] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
