Description

Technical Field

[0001] This utility model belongs to the field of medical technology, and in particular relates to an adjustable flow drug dispensing funnel. Background Technology

[0002] A pharmaceutical dispensing funnel is a medical aid used for the precise dispensing of solid or powdered medications. It typically consists of a conical funnel body and a flow guide tube. Its function is to dispense large doses of medication into smaller packages or containers as needed, ensuring accurate dosage and avoiding cross-contamination. It is mainly used in hospital pharmacies, pharmaceutical workshops, and laboratories, and is suitable for the standardized dispensing of different forms of medication such as tablets, capsules, and powders. It is particularly suitable for the preparation of temporary formulations requiring frequent dosage adjustments or for personalized medication needs of patients. However, during the process of pouring liquid medication into the funnel to dispense it into dispensing bottles, the maximum outflow rate of the funnel is fixed. Therefore, if the liquid is poured in too quickly, it may not flow out rapidly, posing a risk of overflow during continuous pouring. This paper proposes a structure that can prevent liquid overflow from the funnel. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides an adjustable flow rate pharmaceutical packaging funnel, which solves the aforementioned problems.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: an adjustable flow rate drug dispensing funnel, comprising a main funnel with openings at both the top and bottom, wherein a cover plate is fixedly connected to the upper opening of the main funnel, and a screw cylinder is fixedly connected to the through hole at the axis of the cover plate, wherein the outer wall of the screw cylinder is tightly attached to the inner wall of the through hole at the axis of the cover plate, the lower end of the secondary funnel is threadedly connected to the screw cylinder, and the opening at the lower end of the screw cylinder is located inside the main funnel, and a cylinder body is coaxially fixedly connected to the opening on the upper end face of the secondary funnel.

[0005] Beneficial effects

[0006] This invention provides an adjustable flow rate drug dispensing funnel, which has the following advantages compared with the prior art:

[0007] 1. When the user needs to pour the medicine, after connecting the dispensing bottle to the main funnel, the medicine can be poured into the auxiliary funnel all at once. At this time, the medicine can flow into the main funnel through the opening at the lower end of the auxiliary funnel. Since the lower end of the auxiliary funnel enters the main funnel through the cover plate, the medicine can only flow into the dispensing bottle through the main funnel and will not flow out of the main funnel, thus effectively preventing the medicine from overflowing. After observing that the medicine has been emptied, the user can rotate and loosen the auxiliary funnel to remove it from the screw barrel for easy disassembly and cleaning of the auxiliary funnel and the main funnel.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0015] Please see Figures 1-4This invention provides an adjustable flow rate pharmaceutical dispensing funnel, comprising a main funnel 101 with openings at both ends, a cover plate 201 fixedly connected to the upper opening of the main funnel 101, a screw cylinder 202 fixedly connected to a through hole at the axial center of the cover plate 201, the outer wall of the screw cylinder 202 being tightly fitted to the inner wall of the through hole at the axial center of the cover plate 201, a secondary funnel 203 having its lower end threadedly connected to the screw cylinder 202, the opening of the lower end of the screw cylinder 202 being located within the main funnel 101, and a cylinder body 204 coaxially fixedly connected to the opening on the upper end face of the secondary funnel 203; the secondary funnel 203... The maximum volume of the funnel is greater than the maximum volume of the main funnel 101. During use, the main funnel 101 and the auxiliary funnel 203 should be kept horizontal. However, when the liquid in the auxiliary funnel 203 is completely drained into the main funnel 101, the user can tilt the main funnel 101, but the tilt angle should ensure that the liquid can flow out from it. Both the main funnel 101 and the auxiliary funnel 203 are made of transparent material to facilitate observation of the flow of the liquid inside. After use, flowing water will be continuously introduced into the cylinder 204 to rinse the entire structure. After rinsing, the structure will be sterilized at high temperature for recycling.

[0016] In the above embodiment, when the user needs to pour out the medicine, after connecting the dispensing bottle to the main funnel 101, the user can pour the medicine into the auxiliary funnel 203 at once. At this time, the medicine can flow into the main funnel 101 through the opening at the lower end of the auxiliary funnel 203. Since the lower end of the auxiliary funnel 203 enters the main funnel 101 through the cover plate 201, the medicine can only flow into the dispensing bottle through the main funnel 101 after entering the main funnel 101, and there is no situation where it flows out of the main funnel 101, thereby effectively preventing the medicine from overflowing. After observing that the medicine has been drained, the user can rotate and loosen the auxiliary funnel 203 to remove the auxiliary funnel 203 from the screw cylinder 202, so as to facilitate the disassembly and cleaning of the auxiliary funnel 203 and the main funnel 101.

[0017] Specifically, a duckbill valve 205 is fixedly connected to the inner wall of the secondary funnel 203. The duckbill valve 205 is located above the cover plate 201, and the side wall of the duckbill valve 205 is in close contact with the inner wall of the secondary funnel 203. The duckbill end of the duckbill valve 205 faces the cover plate 201. Since the duckbill valve 205 is provided in the secondary funnel 203, it can play a one-way limiting role for the liquid, so that the liquid can only flow along the secondary funnel 203 to the main funnel 101. At this time, even if the main funnel 101 is full of liquid, the liquid in it cannot overflow into the secondary funnel 203.

[0018] Specifically, the main funnel 101 is provided with an adjustment component to prevent the liquid medicine from overflowing from 203. The adjustment component includes a guide plate 206 and a sealing component. The guide plate 206 is fixedly connected to the opening at the lower end of the main funnel 101, and the main funnel 101 and the guide plate 206 are coaxial. A plurality of guide holes 207 are symmetrically arranged on the guide plate 206, and the diameter of the guide holes 207 decreases sequentially in the counterclockwise direction.

[0019] The sealing assembly is used to allow liquid in the main funnel 101 to flow out through any of the guide holes 207.

[0020] Specifically, the sealing assembly includes a sealing plate 208, the upper end face of which is in close contact with the lower end face of the guide plate 206, and the sealing plate 208 and the guide plate 206 are coaxially rotatably connected. A through groove 209 is provided on the sealing plate 208 at a position corresponding to the guide hole 207, and the diameter of the through groove 209 is the same as the diameter of the largest guide hole 207.

[0021] Specifically, the sealing plate 208 is fixedly connected to the inner wall of the connecting pipe 301, and a flexible hose 302 is fixedly connected to the lower end of the connecting pipe 301.

[0022] In the above embodiment, after the user inserts 302 into the dispensing bottle and pours the medicine into the secondary funnel 203, the user can rotate the connecting tube 301 clockwise. This causes the sealing plate 208 fixedly connected inside to begin rotating relative to the guide plate 206. At this time, the diameter of the guide hole 207 opposite the through groove 209 begins to gradually increase. Since the through groove 209 is coaxial with any guide hole 207, only that guide hole 207 is within its range. Therefore, the medicine can flow out from the guide hole 207, which makes it easier to control the flow rate of the medicine. This avoids the medicine flowing out of the cover plate 201 too slowly, which would reduce the rate at which the liquid level in the secondary funnel 203 drops, thus preventing the liquid level inside from overflowing. At the same time, since the guide plate 206 and the sealing plate 208 are in close contact, the medicine can be effectively prevented from seeping out from the gap at their connection.

[0023] Specifically, the connecting pipe 301 is provided with a guide assembly for rotating and guiding it. The guide assembly includes a positioning block 303 and an insert block 304. Multiple positioning blocks 303 are fixedly connected to the outer wall of the main funnel 101, and each of the multiple positioning blocks 303 corresponds to a 307. The insert block 304 is located below the positioning block 303 and is vertically slidably connected to the outer wall of the connecting pipe 301. The multiple positioning blocks 303 are all different colors, and the insert block 304 is located on the side of the through groove 209.

[0024] In the above embodiment, during the process of the user rotating the connecting pipe 301, the rotation position of the connecting pipe 301 can be distinguished by the positioning block 303 facing the insertion block 304, so that the user can accurately locate which guide hole 207 is facing the through groove 209.

[0025] Specifically, the lower surface of the positioning block 303 is provided with a slot 305, and the upper end of the insert block 304 is inserted into the slot 305, with the upper end of the insert block 304 closely attached to the inner wall of the slot 305. After the user rotates the connecting tube 301 and adjusts the contact between the guide hole 207 and the through groove 209, the user can push the insert block 304 upward, thereby inserting the upper end of the insert block 304 into the slot 305, thus limiting the rotation of the connecting tube 301. This prevents the flow rate of the medicine from changing due to accidental contact with the connecting tube 301 after the user adjusts the flow rate of the medicine.

[0026] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0027] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0028] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0029] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0030] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0031] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
