Technical Field
[0001] This utility model relates to the field of biopharmaceutical technology, specifically to a device for quantitative dispensing of biopharmaceuticals that facilitates dispensing. Background Technology
[0002] Freeze-dried human rabies vaccine is an important biological product for the prevention of rabies. The finished product is in powder form and can be exposed to the outside air. When using it, a certain amount of powder must first be taken out, then reconstituted into a liquid with water for injection, and finally injected into the patient using a syringe.
[0003] In the clinical application of rabies vaccines, existing intelligent biopharmaceutical quantitative dispensing equipment, while highly accurate and comprehensive in function, suffers from high equipment costs, system complexity, and maintenance difficulties. This makes it unsuitable for use by small pharmaceutical companies, medical institutions in remote areas, and temporary vaccine distribution points with limited budgets and insufficient technical maintenance capabilities. The current challenge is to design a biopharmaceutical quantitative dispensing device based on a purely mechanical structure that meets usage requirements while ensuring quantitative dispensing accuracy, while also being low-cost and highly reliable. Summary of the Invention
[0004] Therefore, the purpose of this utility model is to provide a convenient device for dispensing and quantitatively dispensing biological drugs, so as to solve the technical problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient dispensing device for quantitative dispensing of biological pharmaceuticals, comprising a storage tank for loading biological pharmaceuticals and a dispensing rack for discharging biological pharmaceuticals; a feeding box is provided at the upper end of the dispensing rack, and a limiting placement rack is provided at the upper end of the feeding box, through which the storage tank can be installed at the upper end of the feeding box, with the dispensing end of the storage tank located inside the feeding box, allowing the biological pharmaceuticals in the storage tank to enter the feeding box; two symmetrical connecting channels are provided between the dispensing rack and the feeding box, through which the biological pharmaceuticals in the feeding box can enter the dispensing rack; two symmetrical discharge ports are provided at the bottom end of the dispensing rack, each of which... The feeding ports allow the biological drugs located in the picking rack to be removed from the picking rack. The picking rack is equipped with two quantitative dispensing racks, which are symmetrically and rotatably installed on both sides of the picking rack. The upper and lower ends of each quantitative dispensing rack correspond to a connecting channel and a feeding port. Each quantitative dispensing rack allows the biological drugs in the connecting channel to be removed from the picking rack in batches and in quantitative quantities through the feeding port. The picking rack is also equipped with a driving component, which is connected to the two quantitative dispensing racks. The driving component allows the two quantitative dispensing racks to rotate within the picking rack, so that the quantitative dispensing racks can transfer the biological drugs in the connecting channel to the feeding port in a rotating state.
[0006] Furthermore, two discharge pipes are symmetrically opened at the bottom of the material receiving rack. Each discharge pipe is tapered, with a wider top and a narrower bottom. The top of each discharge pipe corresponds to a discharge port.
[0007] Furthermore, a limiting placement rack is provided inside the feed box. The limiting placement rack is located in the middle of the two connecting channels, and its top is set with an arc surface. The limiting placement rack allows the biological drugs in the feed box to naturally flow into the two connecting channels.
[0008] Furthermore, the outer wall of the picking rack is provided with a plurality of scale values distributed in a circular interval, and the plurality of scale values are arranged around the driving end of the driving component on the picking rack. The plurality of scale values enable the driving component to effectively observe the rotation position when it is started.
[0009] Furthermore, each of the quantitative dispensing racks is circular, and each quantitative dispensing rack is in contact with the inner wall of the picking rack, with a sealing structure at the contact point between the quantitative dispensing rack and the picking rack; each quantitative dispensing rack has multiple spaced-apart feeding slots, each feeding slot communicating with the connecting channel when it is above the quantitative dispensing rack, and communicating with the discharge port when it is below the quantitative dispensing rack; each quantitative dispensing rack has an installation shaft and a one-way bearing in the middle, the installation shaft is rotatably installed inside the picking rack, the one-way bearing is installed inside the quantitative dispensing rack, and the quantitative dispensing rack is mounted on the installation shaft via the one-way bearing, with the locking structures in the two one-way bearings arranged in opposite directions.
[0010] Furthermore, the drive assembly includes a rotating shaft, a transmission gear, a driven gear, and a knob. The rotating shaft is rotatably mounted on the material handling rack, with one end located inside the rack and the other end outside, situated between two quantitative dispensing racks. The transmission gear is mounted on the rotating shaft inside the rack. Two driven gears are provided, each located inside the rack and mounted on two separate mounting shafts, meshing with the transmission gear on both sides. The knob is located outside the rack and mounted on the rotating shaft. The knob can be rotated by the operator, causing the rotating shaft and transmission gear to rotate. A pointer is mounted on the knob, corresponding to multiple scale values. The operator can easily rotate the knob by coordinating the pointer with the scale values.
[0011] In summary, the present invention has the following main advantages:
[0012] 1. In this utility model, in order to address the problems of high cost and difficult maintenance of intelligent equipment in the background technology, a purely mechanical structure design is adopted. Through the meshing transmission of the knob, rotating shaft, transmission gear and driven gear in the drive component, the quantitative dispensing racks on both sides are driven to rotate. With the cooperation of two one-way bearings set in opposite directions, the dispensing racks work alternately when the knob rotates forward and reverse (one side is filling while the other side is dispensing). There is no need for an electronic control system, which directly reduces the equipment cost and simplifies the maintenance process. It solves the problem that small pharmaceutical companies and medical institutions in remote areas have limited budgets and insufficient technical maintenance capabilities, making it difficult for them to use existing equipment.
[0013] 2. In this utility model, the arc-shaped limiting rack inside the feeding box can symmetrically divert the biological drugs flowing into the storage tank to the connecting channels on both sides, avoiding errors caused by manual diversion; the quantitative dispensing rack, through the cooperation of the feeding trough and the conical discharge pipe, realizes the batch quantitative dispensing of drugs by mechanical rotation. At the same time, the sealing structure of the inner wall of the dispensing rack and the picking rack prevents leakage, ensuring quantitative accuracy without relying on electronic control, and meeting the clinical requirements for vaccine dosage accuracy.
[0014] 3. In this utility model, the visual design of the scale on the outside of the dispensing rack and the knob pointer allows operators to accurately control the rotation angle to adjust the dispensing dosage, and can be operated without complicated training; the symmetrical layout of the quantitative dispensing racks on both sides, combined with the alternating forward and reverse working mode of the knob, can realize the simultaneous output of dual doses, improve dispensing efficiency, and is especially suitable for scenarios such as temporary vaccine distribution points where rapid quantitative dispensing is required, effectively solving the problem that existing equipment is difficult to apply in resource-constrained scenarios.

Detailed Implementation
[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0022] The embodiments of this utility model will be described below based on its overall structure. Example
[0023] Overall structural layout of the equipment in this application
[0024] The biopharmaceutical quantitative dispensing device in this application mainly consists of a storage tank, a feed box 2, a dispensing rack 1, a quantitative dispensing rack 4, and a drive assembly 5. The storage tank is vertically mounted above the feed box 2 via a fixed placement rack 21, and its discharge end extends into the interior of the feed box 2 and remains sealed. Two connecting channels 3 are symmetrically arranged at the bottom of the feed box 2, communicating with the interior of the dispensing rack 1. Two discharge ports and a conical discharge pipe 12 are correspondingly arranged at the bottom of the dispensing rack 1.
[0025] A limiting shelf 22 is installed at the center of the inside of the feed tank 2, and its top is designed with an arc surface structure. When the biological drug flows from the storage tank into the feed tank 2, the drug solution naturally flows along the arc surface to the connecting channels 3 on both sides.
[0026] Two circular quantitative dispensing racks 4 are symmetrically installed inside the feeding rack 1. The gap between the outer diameter of the dispensing rack and the inner wall of the feeding rack 1 is controlled at 0.05-0.15mm, and a food-grade silicone sealing ring is used to achieve dynamic sealing. Each dispensing rack has 6-12 feeding slots 41 evenly distributed around its circumference. The dispensing rack is connected to the mounting shaft 42 through a one-way bearing 43. The locking directions of the two one-way bearings 43 are opposite, ensuring that the dispensing rack can alternately fill and discharge under different rotation directions.
[0027] The working principle described in this application
[0028] This invention achieves precise diversion of biological pharmaceutical powder through a gravity-fed material conveying system. Under the action of gravity, the biological pharmaceutical powder in the storage tank 1 flows into the feed box 2 along the discharge end 11. The arc-shaped structure of the limiting placement frame 23, based on the principle of bulk flow in particle mechanics, makes the powder form a symmetrical parabolic flow pattern, ensuring that the powder flow deviation of the connecting channels 22 on both sides is ≤±2%.
[0029] The reverse arrangement of the two one-way bearings 43 forms a mechanical logic switching system:
[0030] Counterclockwise rotation mode: When knob 51 is turned counterclockwise, transmission gear 55 drives the left driven gear 53 to rotate counterclockwise. The left one-way bearing 43 enters the locking state, and the wedge engages with the inner and outer rings, causing the left quantitative dispensing frame 4 to rotate synchronously. At this time, the right driven gear 53 rotates clockwise, but the right one-way bearing 43 is in a free state, the wedge slips, and the right quantitative dispensing frame 4 remains stationary.
[0031] Clockwise rotation mode: When knob 51 is turned clockwise, the right one-way bearing 43 locks, causing the right quantitative dispensing rack 4 to rotate while the left quantitative dispensing rack 4 remains stationary. This alternating action mechanism is achieved mechanically, without the need for electronic control, ensuring system reliability with an MTBF ≥ 5000 hours.
[0032] Work process and operating methods
[0033] Rotate knob 54 to the "0" mark. At this time, the feeding trough 41 in the left quantitative dispensing rack 4 and the right quantitative dispensing rack 4 are aligned with the corresponding connecting channel 3 and feeding port 11.
[0034] Note: The volume of the left discharge tank 41 is V1, for example, 0.5ml, and the volume of the right discharge tank 41 is V2, for example, 1.0ml. Dual dose output can be achieved by adjusting the V1 / V2 ratio.
[0035] Quantitative material feeding cycle
[0036] Rotate the knob counterclockwise 54 to 180°:
[0037] The left quantitative dispensing rack 4 is locked by the one-way bearing 43. As the driven gear 53 rotates counterclockwise, the 6 dispensing troughs 41 can sequentially complete the V1 dosage filling through the connecting channel 3. Then, the V1 dosage can be discharged by continuing to rotate the knob 54.
[0038] At this time, the right-side sub-packaging rack is unlocked due to the one-way bearing 43, and the driven gear 53 rotates freely and remains stationary.
[0039] Rotate the knob clockwise 54 to 180°:
[0040] The right-side quantitative dispensing rack 4 is locked by the one-way bearing 43. As the driven gear 53 rotates clockwise, the 6 dispensing troughs 41 can sequentially complete the V2 dosage filling. Then, the V2 dosage can be dispensed by continuing to rotate the knob 54.
[0041] At this time, the left quantitative dispensing rack 4 is unlocked due to the one-way bearing 43, and the driven gear 53 rotates idling and remains stationary.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, but such modifications, substitutions, and variations are protected by patent law as long as they fall within the scope of the claims of the present invention.
