Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical packaging equipment technology, specifically a pharmaceutical packaging leak-proof guide device. Background Technology

[0002] In the pharmaceutical industry, drug production, hospital pharmacy drug dispensing, and research institution drug experiments, it is often necessary to repackage liquid drugs (such as injections and oral liquids) or powdered drugs (such as powders and pharmaceutical powder raw materials).

[0003] Currently, most common dispensing methods rely on traditional flow guides to directly connect the drug storage container and the dispensing container. However, in actual operation, the following problems exist: traditional flow guides do not have flow regulation function. When dispensing liquid drugs of different viscosities, it is impossible to control the drug flow rate according to the needs. If the flow rate is too fast, it is easy to generate air bubbles and cause leakage. If the flow rate is too slow, it will reduce the dispensing efficiency. Therefore, it is urgent to design a drug dispensing anti-leakage flow guide to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a leak-proof drug dispensing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A leak-proof flow guide for drug dispensing includes a first connecting pipe and a second connecting pipe. A flow guide is fixedly installed at the bottom of the first connecting pipe and the top of the second connecting pipe via flanges. A flow guide shroud is fixed to the top of the inner wall of the flow guide. The inner circumference of the flow guide shroud is designed to be inclined. An installation hole is provided at the center of the bottom of the flow guide shroud, and an installation shaft is rotatably connected to the inner wall of the installation hole via a bearing. An adjusting disc is fixedly installed at the bottom of the installation shaft. The adjusting disc has equally spaced second flow guide holes, and the bottom of the flow guide shroud has equally spaced first flow guide holes. The positions of the first and second flow guide holes correspond to the positions of the second flow guide holes. A flow regulating component for driving the adjusting disc to rotate is provided on the flow guide pipe.

[0007] Furthermore, both the first connecting tube and the second connecting tube are hollow tubes made of transparent medical-grade PVC material, and the diameters of the first connecting tube and the second connecting tube gradually decrease from one end to the other.

[0008] Furthermore, the flow regulating component includes a mounting frame fixed to one side of the guide tube, and a through groove communicating with the inside of the mounting frame is opened on one side of the guide tube. An L-shaped rack plate is slidably arranged on the inner wall of the through groove. The outer wall of the regulating disc is provided with equally spaced toothed grooves, which mesh with the L-shaped rack plate. A threaded rod is rotatably arranged on the mounting frame, and a threaded hole is opened at one end of the L-shaped rack plate to be threaded to the threaded rod. A knob is fixed at one end of the threaded rod.

[0009] Furthermore, annular grooves are provided at the top edge of the adjusting disc and the bottom edge of the flow guide, and a first sealing ring is provided in the annular groove.

[0010] Furthermore, a flow guide bowl is fixed to the inner wall of the second connecting pipe, and multiple flow equalization holes are opened at the bottom of the flow guide bowl.

[0011] Furthermore, a second sealing ring is fixedly installed on the top of the inner wall of the first connecting pipe and the bottom of the inner wall of the second connecting pipe, and a tightening clamp is fixedly installed on the top of the outer wall of the first connecting pipe and the bottom of the outer wall of the second connecting pipe.

[0012] Furthermore, the inner walls of the first connecting pipe, the guide pipe, the second connecting pipe, the guide bowl, the guide shroud, the first guide hole, the second guide hole, and the flow equalization hole are all coated with an anti-residue coating.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the flow regulating component can drive the regulating disk to rotate, causing the overlapping area of ​​the first and second guide holes to change, thereby achieving precise control of the flow rate from fast to slow. This allows for adjustment to a suitable flow rate for different viscosities of liquid medicines or different flow rates of powder medicines, avoiding both excessively fast flow rates that cause air bubbles and leakage, and excessively slow flow rates that reduce dispensing efficiency.

[0015] In this invention, all inner walls that come into contact with the medicine are coated with a polytetrafluoroethylene anti-residue coating, which makes the surface tension of the inner wall of the flow guide extremely low, making it difficult for the medicine to adhere to the inner wall of the flow guide component, thus greatly reducing the amount of medicine remaining after dispensing.

[0016] In this invention, the diameters of the first and second connecting pipes gradually decrease from one end to the other. Combined with the tightening clamps at both ends, they can securely connect to drug storage containers and dispensing containers of different diameters. At the same time, the first and second connecting pipes are made of transparent medical PVC material, allowing for direct observation of the drug flow status and early detection of abnormalities such as blockages and leaks, thereby reducing drug waste and environmental pollution caused by leakage.

[0017] In this invention, the guide bowl and the bottom flow equalization hole in the second connecting tube can make the medicine flow evenly before entering the dispensing container, so as to avoid the medicine from being concentrated and impacted in the second connecting tube, generating turbulence or bubbles, and ensuring that the medicine flows into the dispensing container in a stable and uniform state.

[0024] 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.

[0025] Please see Figures 1-5In this embodiment of the present invention, a leak-proof drug dispensing guide includes a first connecting pipe 1 and a second connecting pipe 3. A guide pipe 2 is fixedly installed at the bottom of the first connecting pipe 1 and the top of the second connecting pipe 3 via a flange. A guide shroud 9 is fixedly installed on the top of the inner wall of the guide pipe 2. The inner circumferential wall of the guide shroud 9 is designed to be inclined. A mounting hole 14 is provided at the center of the bottom of the guide shroud 9. A mounting shaft 15 is rotatably connected to the inner wall of the mounting hole 14 via a bearing. An adjusting disc 7 is fixedly installed at the bottom of the mounting shaft 15 for adjustment. Annular grooves 13 are provided at the top edge of the disc 7 and the bottom edge of the guide shroud 9, and a first sealing ring 8 is provided in the annular groove 13. Second guide holes 12 are evenly distributed through the disc 7, and first guide holes 11 are evenly distributed through the bottom of the guide shroud 9. The positions of the first guide holes 11 correspond to the positions of the second guide holes 12. A flow regulating component 5 for driving the disc 7 to rotate is provided on the guide pipe 2. The flow regulating component 5 includes a mounting bracket fixed to one side of the guide pipe 2. The mounting frame 52 has a through groove 51 on one side of the guide pipe 2 that communicates with the interior of the mounting frame 52. An L-shaped rack plate 54 is slidably arranged on the inner wall of the through groove 51. The outer wall of the adjusting plate 7 has equally spaced toothed grooves 56 that mesh with the L-shaped rack plate 54. A threaded rod 53 is rotatably arranged on the mounting frame 52. One end of the L-shaped rack plate 54 has a threaded hole that is threaded to the threaded rod 53. A knob 55 is fixed to one end of the threaded rod 53. Rotating the knob 55 of the flow regulating component 5 drives the threaded rod. 53 rotates within the mounting frame 52, causing the L-shaped rack plate 54 to slide along the through groove 51. Through meshing with the toothed groove 56 on the outer wall of the adjusting plate 7, it drives the adjusting plate 7 to rotate around the mounting shaft 15, thereby changing the overlapping area of ​​the second guide hole 12 and the first guide hole 11 on the adjusting plate 7, achieving precise control of the drug flow rate. Thus, for different viscosities of liquid drugs or different flow rates of powder drugs, the flow rate can be adjusted to a suitable level, avoiding both excessively fast flow rates that cause air bubbles and leakage, and excessively slow flow rates that reduce dispensing efficiency.

[0026] Specifically, the first connecting pipe 1 and the second connecting pipe 3 are both hollow tubes made of transparent medical-grade PVC material, and the diameter of the first connecting pipe 1 and the second connecting pipe 3 gradually decreases from one end to the other. This allows for direct observation of the flow of medicine, early detection of abnormalities such as blockage and leakage, and reduction of medicine waste and environmental pollution caused by leakage.

[0027] Specifically, a flow guide bowl 6 is fixed to the inner wall of the second connecting pipe 3, and multiple flow equalization holes 16 are opened at the bottom of the flow guide bowl 6, which can make the medicine flow evenly before entering the dispensing container, avoid the medicine from being concentrated and impacted in the second connecting pipe 3, generating turbulence or bubbles, and ensure that the medicine flows into the dispensing container in a stable and uniform state.

[0028] Specifically, a second sealing ring 10 is fixedly installed on the top of the inner wall of the first connecting pipe 1 and the bottom of the inner wall of the second connecting pipe 3, and a tightening clamp 4 is fixedly installed on the top of the outer wall of the first connecting pipe 1 and the bottom of the outer wall of the second connecting pipe 3.

[0029] Specifically, the inner walls of the first connecting pipe 1, the guide pipe 2, the second connecting pipe 3, the guide bowl 6, the guide cover 9, the first guide hole 11, the second guide hole 12 and the equalizing hole 16 are all coated with an anti-residue coating, and the anti-residue coating is a polytetrafluoroethylene coating to reduce drug adhesion.

[0030] The working principle of this utility model is as follows: When working, the medicine enters from the first connecting pipe 1, is guided by the guide shroud 9 in the guide pipe 2, and flows along the inclined inner circumferential wall of the guide shroud 9 to the first guide hole 11 at its bottom;

[0031] When flow rate needs to be adjusted, turn the knob 55 of the flow rate adjustment component 5 to drive the threaded rod 53 to rotate in the mounting frame 52, so that the L-shaped rack plate 54 slides along the through groove 51. Through the meshing action with the toothed groove 56 on the outer wall of the adjustment plate 7, the adjustment plate 7 is driven to rotate around the mounting shaft 15, thereby changing the overlapping area of ​​the second guide hole 12 and the first guide hole 11 on the adjustment plate 7, so as to achieve precise control of the drug flow rate.

[0032] The adjusted medicine enters the second connecting tube 3 through the second guide hole 12, and is then guided by the guide bowl 6 in the second connecting tube 3 to the equalization hole 16 at its bottom. After being evenly distributed through the equalization hole 16, it flows into the dispensing container.

[0033] Throughout the process, the first connecting pipe 1 and the second connecting pipe 3, with their gradually changing diameter design and tightening clamp 4, securely connect to containers of different diameters. The second sealing ring 10 enhances the sealing at the connection point. The first sealing ring 8 in the annular groove 13 at the edge of the adjusting plate 7 and the flow guide shroud 9 prevents leakage of medicine at the contact point. At the same time, the anti-residue coating on the inner walls of the first connecting pipe 1, the flow guide pipe 2, the second connecting pipe 3, the flow guide bowl 6, the flow guide shroud 9, the first flow guide hole 11, the second flow guide hole 12, and the flow equalization hole 16 reduces the adhesion of medicine. The transparent first connecting pipe 1 and the second connecting pipe 3 facilitate the observation of the flow state of the medicine, ensuring that the dispensing process is leak-proof, the flow rate is controllable, and the residue is reduced.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
