Description

Technical Field

[0001] This application relates to the field of medicine storage bottle technology, specifically a mother-daughter medicine bottle. Background Technology

[0002] In modern medicine, many drugs, especially high-concentration liquid formulations, require temporary mixing and reconstitution before use. A common scenario is transferring one drug from vial A to vial B containing another drug to create a usable mixed solution. Currently, this mixing process relies entirely on syringes as the transfer tool: the operator must first use a syringe to puncture and draw the drug solution from vial A, and then inject it into vial B, thus achieving drug transfer and mixing.

[0003] However, existing technologies have the following significant drawbacks: 1. Cumbersome and time-consuming operation: The entire drug mixing process requires multiple punctures, aspirations, transfers, and injections, making the steps complex. This is particularly time-consuming for medical staff in busy medical environments, or when patients perform the procedure themselves, significantly impacting efficiency.

[0004] 2. Increased risk of contamination: The syringe needle needs to puncture the rubber stopper of different vials twice, which increases the risk of the drug solution being exposed to environmental microorganisms or contamination of the operator's hands.

[0005] 3. Needlestick injury and occupational exposure risk: The procedure involves needle exposure, needle capping, or other procedures, posing a high risk of accidental needlestick injury to healthcare workers or patients.

[0006] 4. Operational complexity and learning threshold: For non-professionals, it is difficult to accurately master aseptic operation, precise aspiration and injection techniques, which can easily lead to operational errors or dosage deviations.

[0007] In view of the many shortcomings of the existing technology, the present invention proposes an innovative "mother-daughter medicine bottle" structure. Utility Model Content

[0008] This application provides a mother-daughter medicine bottle that can be connected together to achieve drug mixing, avoiding the use of syringes and effectively solving the problems in the prior art.

[0009] To achieve the above objectives, this application provides the following technical solution: a mother-daughter medicine bottle, comprising a mother bottle body and a daughter bottle body; the mother bottle body and the daughter bottle body are assembled together by insertion; a rubber stopper is provided at the mouth of the mother bottle body; The outer side of the sub-bottle body is provided with a detachable sealing cap one and a sealing cap two at the upper and lower ends respectively.

[0014] Preferably, the length of the arc-shaped baffle is the same as the length of the pressure column located on the bottle body, and the outer side of the arc-shaped baffle is provided with a pull lug.

[0015] Compared with the prior art, the beneficial effects of this application are: 1. In this application, the sub-bottle and the mother bottle are directly connected → the pressure plate is pressed → the puncture needle penetrates the rubber stopper → the medicine is automatically mixed; the operation steps are few and the mixing time is short, which is especially suitable for emergency scenarios; the puncture needle of the sub-bottle is sealed inside the sealing cap 2 throughout the process; the transfer of medicine is completed directly between the sealed bottles, which can effectively reduce air contact.

[0016] 2.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] In the description of this application, if directional descriptions are involved, such as "up," "down," "front," "back," "left," "right," etc., indicating directional or positional relationships, they are based on the appendix. Figure 2 The orientations or positional relationships shown are for the convenience of describing this application and simplifying the description only, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. When a feature is referred to as "set", "fixed", or "connected" to another feature, it can be directly set, fixed, or connected to the other feature, or it can be indirectly set, fixed, or connected to the other feature.

[0021] Please see Figure 1-7 This application provides the following technical solution: a mother bottle body 1 and a daughter bottle body 2; the mother bottle body 1 and the daughter bottle body 2 are assembled together by insertion; a rubber stopper 7 is provided at the mouth of the mother bottle body 1.

[0022] The outer side of the sub-bottle body 2 is provided with a detachable sealing cap 4 and a sealing cap 8 at the upper and lower ends respectively. The inner side of the sub-bottle body 2 is provided with a cylindrical sealing plug 12. The upper surface of the cylindrical sealing plug 12 is connected to a pressure column 10. The upper end of the outer side of the pressure column 10 passes through the sub-bottle body 2 and is connected to a pressure plate 9. The outer side of the pressure column 10 is fitted with an arc-shaped baffle 17, which is snapped onto the outer side.

[0023] Specifically, the plug-in assembly design significantly simplifies the operation process, enabling rapid and accurate docking of the mother and daughter bottles, avoiding the complex steps of traditional syringe transfer; the rubber stopper 7 acts as a one-way sealed barrier, ensuring the sterile isolation of the mother bottle solution before mixing, while providing a resealable puncture interface for the puncture needle, reducing the risk of solution contamination.

[0024] More specifically, the sealing cap 1 4 protects the operating end of the pressure column, and the sealing cap 2 8 completely covers the puncture needle 14, eliminating the risk of needlestick injury from the source; the pressure column-sealing plug linkage mechanism achieves zero-residue transfer of the drug solution through mechanical pressurization, ensuring accurate dosage; the arc-shaped baffle 17 serves as an anti-accidental contact locking structure to prevent drug solution leakage caused by accidental pressing during transportation or operation.

[0025] The lower left and right sides of the outer side of the sub-bottle body 2 are provided with arc-shaped positioning plates 13, and the lower end face of the sub-bottle body 2 is provided with a puncture needle 14.

[0026] Specifically, the symmetrical arc-shaped positioning plate 13 and the annular metal cap 6 at the mouth of the mother bottle form a snap-fit ​​positioning to ensure that the puncture needle 14 and the rubber stopper 7 are vertically aligned, avoiding sealing failure caused by puncture deviation; the built-in puncture needle 14 is hidden inside the daughter bottle throughout the process, with no needle exposed during operation, completely avoiding occupational exposure risks.

[0027] Furthermore, the upper surface of the rubber stopper 7 is provided with an I-shaped plastic pressure plate 5, which is pressed tightly onto the rubber stopper 7 by an annular metal sealing cap 6.

[0028] Specifically, the I-shaped plastic pressure plate 5 combined with the metal pressure cap 6 forms a composite sealing and pressing structure: the metal pressure cap provides high-strength radial locking force, the I-shaped pressure plate disperses puncture stress, and the rubber stopper 7 is doubly protected in terms of sealing reliability and anti-puncture fatigue performance, thus extending the storage life of the mother bottle.

[0029] Furthermore, the sealing cap 4 is connected to the sub-bottle body 2 via the top thread 11.

[0030] Specifically, the threaded interface provides a standardized sealing solution that can be repeatedly opened, adapting to automated production line packaging; the annular anti-slip texture 3 increases operating friction, ensuring quick unscrewing of the sealing cap in emergency scenarios; the pull lug 16 serves as a human-machine interface contact point, enabling one-handed unlocking of the arc-shaped baffle 17, improving operational smoothness.

[0031] Furthermore, the upper outer surface of the sealing cap 4 is provided with annular anti-slip texture 3.

[0032] Furthermore, the sealing cap 28 is connected to the sub-bottle body 2 via the bottom thread 15.

[0033] Furthermore, the length of the arc-shaped baffle 17 is the same as the length of the pressure column 10 located on the bottle body 2 of the sub-bottle, and the outer side of the arc-shaped baffle 17 is provided with a pull lug 16.

[0034] Specifically, the constant stroke design of the arc-shaped baffle 17 precisely limits the pressing depth of the pressure column 10: it ensures that the cylindrical sealing plug 12 fully pushes the drug solution into the sub-bottle (avoiding residue), and prevents excessive pressing from causing secondary damage to the rubber stopper 7 by the puncture needle 14, thus forming a physical protection against misoperation.

[0035] In use: First, use a tool to pry open the I-shaped plastic pressure plate 5, exposing the rubber stopper 7. Then, remove the sealing cap 8 from the sub-bottle body 2. Place the arc-shaped positioning plate 13 on the outer side of the annular metal sealing cap 6, and press down the sealing cap 4, causing the puncture needle 14 to pierce the rubber stopper 7. Open the sealing cap 4, and finally pull open the arc-shaped baffle 17. Press down the pressure plate 9, and the pressure column 10 will push the cylindrical sealing plug 12 down, injecting the medicine from the sub-bottle body 2 into the mother bottle body 1. This completes the mixing of the medicine.

[0036] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
