Abstract
Description
Technical Field
[0001] This utility model relates to the packaging industry, and in particular to a roll-on ampoule delivery device. Background Technology
[0002] In the medical and daily care fields, ampoules are a commonly used pharmaceutical packaging container with many advantages. Ampoules are typically made of glass, offering excellent sealing properties that effectively prevent contamination of medications, ensuring their quality and stability. They are widely used for storing various injectable and oral liquid preparations.
[0003] However, in practical use, the medication delivery methods associated with ampoules have significant shortcomings. Currently, in clinical and daily use, it is difficult to accurately and conveniently extract medication from ampoules and administer it to patients. Traditional methods often require the use of a syringe, which is cumbersome, demands high user skills, and is prone to medication waste during extraction, while also increasing the risk of infection. Furthermore, for some medications requiring topical application, there is a lack of convenient application tools when they are contained in ampoules. For example, in dermatological treatments, some topical medications are often contained in ampoules. Medical staff or patients often have to pour the medication onto a cotton ball before application, which makes it difficult to accurately control the dosage, easily leading to unnecessary medication loss and uneven application, affecting the treatment effect. In the beauty industry, ampoule-packaged serums and other products face similar problems; consumers expect a more convenient, hygienic method that allows for precise dosage control.
[0004] While some roll-on drug delivery devices exist on the market, most are independently designed and do not adequately consider compatibility with ampoules, making them unsuitable for direct connection and failing to effectively address the inconvenience of ampoule-based drug delivery. Therefore, a roll-on ampoule drug delivery device has been proposed. Utility Model Content
[0005] This invention addresses the shortcomings of existing technologies by using a through-hole at the bottom of the lower shell in conjunction with a cutting structure, and positioning ribs for guidance and fixation, thus retaining waste material, preventing glass shards from flying, and ensuring safety and the cleanliness of the medication. The combination of the upper shell, ball bearing structure, and sealing cap allows the medication to flow evenly from the sealing plate's through-hole to the ball bearing during administration, and the rolling motion ensures precise drug delivery, making ampoule medication administration more convenient.
[0006] To solve the above-mentioned technical problems, this utility model solves the problem of inconvenient drug administration using traditional ampoules through the following technical solution.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] An ampoule delivery device includes: a lower housing and an upper housing that cooperates with the lower housing. A cavity for accommodating an ampoule is formed between the lower housing and the upper housing. A sealing plate for abutting the ampoule mouth is provided at the upper opening of the cavity. A ball bearing structure is provided on the other side of the sealing plate. A through hole communicating between the ball bearing structure and the cavity is provided in the middle of the sealing plate.
[0009] Preferably, the bottom of the lower housing has a through opening, and its inner peripheral wall has a ring array of cutting structures. The cutting structures include positioning ribs extending along the axial direction for fixing the neck of the ampoule and guiding it to break.

Example
[0033] Please see Figure 1-7 An ampoule delivery device includes: a lower housing 1 and an upper housing 2 that cooperates with the lower housing 1. A cavity for accommodating an ampoule 5 is formed between the lower housing 1 and the upper housing 2. A sealing plate 8 for abutting the ampoule mouth is provided at the upper opening of the cavity. A ball bearing structure 3 is provided on the other side of the sealing plate 8. A through hole connecting the ball bearing structure 3 and the cavity is provided in the middle of the sealing plate 8.
[0034] The ampoule-type drug delivery device of this application is mainly composed of a lower shell 1, an upper shell 2, a ball bearing structure 3, a sealing cap 4, an ampoule body 5, and a cutting structure 6. The following is a detailed description of its structure and working principle.
[0035] I. Detailed Structure and Connection Methods of Each Component
[0036] Assembly process: First, insert the ampoule body 5 through the through opening at the bottom of the lower housing 1, so that the neck of the ampoule body 5 mates with the cut structure 6 on the inner circumferential wall of the lower housing 1. The positioning rib 601 guides the ampoule body 5 into place and fixes the part above its neck. Next, screw the upper housing 2 with the ball bearing structure 3 onto the top opening of the lower housing 1 through the first threaded connection structure. The ball bearing structure 3 is fixed to the top of the inner cavity of the upper housing 2 through the engagement of the sealing plate 8 and the ball bearing holder 7. Finally, screw the sealing cap 4 onto the top opening of the upper housing 2 through the second threaded connection structure. The annular protrusion 401 on the top of the inner wall of the sealing cap 4 positions the ball bearing structure 3.
[0037] Open the ampoule 5: Following the guidance of the positioning rib 601 of the cutting structure 6, disconnect the neck of the ampoule 5. The waste part is left in the lower shell 1 and can be easily removed from the top opening to avoid glass fragments flying and falling.
[0038] Observation and Connection: After removing the waste material, insert and secure the ampoule body 5 containing the medication through the opening of the lower housing 1. Rotate the upper housing 2 to ensure a tight connection with the lower housing 1, so that the opening of the ampoule body 5 rests against the sealing plate 8, in preparation for the next step of inverted medication administration. At this time, the remaining medication in the ampoule body 5 can be observed through the transparent viewing window 101 on the upper side wall of the lower housing 1.
[0039] Drug administration procedure: Open the sealing cap 4. The medication in the ampoule 5 flows through the opening between the bottom of the ball bearing holder 7 and the sealing plate 8 onto the surface of the ball bearing structure 3. Since the ball bearing structure 3 is rotatably connected to the ball bearing holder 7, the user can achieve uniform drug administration by rolling the ball bearing structure 3, meeting the needs of local application or precise small-dose administration. The porous mesh structure of the sealing plate 8 further homogenizes the medication.
[0040] Preserving the medication: After use, tighten the sealing cap 4. The annular protrusion 401 inside the sealing cap 4 presses against the ball bearing structure 3 to prevent the ball bearing from rolling when not in use, thus preserving the unused medication in the ampoule bottle 5 inside the delivery device.
[0041] II. Working Principle
[0042] This ampoule roll-on drug delivery device, with its ingenious structural combination and synergistic operation, achieves a safe, accurate, and convenient drug delivery process as well as effective drug preservation.
[0043] Before use, the ampoule body 5 must be opened. The through opening at the bottom of the lower housing 1 and the cutting structure 6 constitute a safe opening system. When the ampoule body 5 is inserted into the through opening, the positioning ribs 601 extending axially on the cutting structure 6 play a crucial role. These positioning ribs 601 act like precise tracks, guiding the ampoule body 5 into accurate position and firmly securing the part above the neck of the ampoule body 5. With the assistance of the positioning ribs 601, the user only needs to apply appropriate external force, and the neck of the ampoule body 5 can be broken off in a preset manner. The positioning ribs 601 are designed as 4-6 sets of circumferentially distributed strip-shaped protrusions, which can position the neck of the ampoule body 5 from multiple directions, ensuring that it is centered in the lower housing 1, making the opening operation more stable. At the same time, the waste part after breaking will naturally remain in the lower housing 1, avoiding the risk of glass shards flying everywhere as in the traditional manual breaking method, protecting the safety of medical personnel and preventing the medication from being contaminated.
[0044] After opening the ampoule 5 and removing the waste, a cavity is formed between the lower shell 1 and the upper shell 2 to accommodate the ampoule 5. The portion of the ampoule 5 containing the medication is then connected to the lower shell 1. At this point, the top of the ampoule 5 extends into the upper shell 2 and rests against the sealing plate 8. The sealing plate 8 has a through hole in the middle that connects the ball bearing structure 3 and the cavity. Under the influence of gravity and liquid surface tension, the medication slowly flows into the through hole in the middle of the sealing plate 8, allowing it to flow into the ball bearing holder 7. The rolling connection between the ball bearing holder 7 and the ball bearing structure 3 ensures that the medication is more smoothly and evenly applied to the surface of the ball bearing structure 3. When medication is needed, the user simply needs to gently roll the ball bearing structure 3. As the ball bearing rolls, it evenly applies the medication adhering to its surface to the desired area, achieving precise and even local application or small-dose administration, effectively meeting the medication needs in special scenarios.
[0045] After the medication is administered, tighten the sealing cap 4 again. At this time, the annular protrusion 401 on the top of the inner wall of the sealing cap 4 will precisely position and moderately press the ball bearing structure 3. This design ensures that the ball bearing structure 3 will not roll randomly when not in use, avoiding unnecessary leakage of the medication; on the other hand, the threaded connection between the sealing cap 4 and the upper shell 2 forms a relatively sealed space, properly storing any unused medication in the ampoule 5, effectively extending the shelf life of the medication, and overcoming the limitation of traditional ampoules that must be used immediately after opening, thus improving the efficiency and economy of medication use.
[0046] Medication Liquid Remaining Level Observation: Throughout the entire use process, the transparent viewing window 101 on the upper side wall of the lower shell 1 plays an important role. Through this window, the user can intuitively observe the remaining amount of medication in the ampoule 5 at any time, thereby making advance medication planning and preparation, and avoiding situations where insufficient medication affects treatment.
[0047] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
