Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of the structure of medicine bottle, specifically relates to a double cavity penicillin bottle structure convenient to use. BACKGROUND

[0002] Injection is one of the most common drug forms at present, and the injection drug has rapid and reliable effect, whether it is stored in liquid form or powder form, and when it is used in clinic, it is directly injected into the tissue, blood vessel or organ of human body in liquid state, so the absorption is rapid; especially for intravenous injection, the drug solution can directly enter the blood circulation, which is more suitable for rescuing critical illness, and the injection does not pass through the gastrointestinal tract and is not affected by the digestive system and food, so the dose is accurate and the effect is reliable.

[0003] The penicillin bottle, also known as borosilicate glass or sodium calcium glass tube (molded) injection bottle, is a small bottle with a rubber plug and an aluminum-plastic combined cover seal, which is one of the most commonly used medicine storage devices for injection drug administration. At present, the first problem that medical staffs face when using the penicillin bottle is opening difficulty, which mainly includes aluminum-plastic bottle cap opening difficulty and rubber plug opening difficulty at the bottle opening. In the prior art, the aluminum-plastic bottle cap opening difficulty is mainly optimized, for example, a penicillin bottle opener disclosed in Chinese patent 2024204006129 overcomes the aluminum-plastic bottle cap opening difficulty by means of machine external object. The limitation of this patent is that the opener needs to be connected to the power supply, but this requirement is often difficult to meet in the actual working environment, thus limiting the use scenario and being not conducive to large-scale promotion. In addition, a penicillin bottle stripping device disclosed in Chinese patent 2024203858545 can be used without connecting to the power supply, which expands the use scenario and is not limited by the environment, but the device is complex and includes a first stripping part, a second stripping part and a stripping handle, which makes the whole use very inconvenient, even requiring a period of learning when first used, and the subsequent maintenance and repair cost of the device is high. Although the use scenario is overcome, it is still not conducive to large-scale promotion.

[0004] In daily use, in addition to the aluminum-plastic bottle cap opening difficulty mentioned above, the penicillin bottle also has the problem of rubber plug opening difficulty, and due to the development of the injection field, the dosage form has evolved from traditional injection liquid to freeze-dried preparation with better stability and more favorable storage, which requires medical staffs to open multiple penicillin bottles for configuration when using. If the problems of penicillin bottle opening difficulty and complicated operation are not solved, it will seriously affect the drug efficiency of medical staffs and further affect the treatment process. UTILITY MODEL CONTENTS

[0005] The utility model discloses a purpose is to provide a kind of can solve together with aluminium-plastic bottle cap of penicillin bottle and rubber plug opening difficult problem, it is convenient to use, simultaneously can be applicable and improve the double-cavity penicillin bottle of existing freeze-dried preparation storage and use mode.

[0006] The inventor believes that, after studying the structure of the penicillin bottle, the optimal solution to the opening difficulty of the aluminium-plastic bottle cap and the rubber plug is still to start from the structure of the aluminium-plastic bottle cap and the rubber plug itself, and rely on "external objects" such as cap openers and cap stripping devices, which will have limitations in application range and use scenarios. In addition, the structure of such devices is usually complex, and subsequent maintenance is also a problem to be faced. Therefore, the inventor believes that by changing the structure of the aluminium-plastic bottle cap and the rubber plug itself and the structure associated therewith, the current difficulty in using the penicillin bottle can be better solved.

[0007] Meanwhile, due to the development of the injection preparation field, the proportion of traditional injection liquid preparations has decreased, and the proportion of freeze-dried preparations has increased. Although freeze-dried preparations are more conducive to the stability and storage of preparations, the complexity of their operation is also increased when used. The inventor has investigated the solutions to such problems in the prior art. In Chinese Patent 2023107843483, a double-cavity structure that can be reused is disclosed. The inventor tried to reproduce this structure, and in the process of reproduction, the inventor found that this technical solution, as an invention patent, did not fully disclose the specific material selection in the protected structure, and the technical personnel could not understand it from the prior art. In this patent, the structure for separating the cavities is a piston. As is known, the piston has a service life and cannot be reused. Due to the particularity of the piston material, the residue of some drugs cannot be completely removed, which is quite different from the viewpoint of reusability proposed by the patent applicant. Moreover, the invention stores the freeze-dried powder and the solvent separately in the upper and lower cavities, which are separated by a piston. In use, the solvent in the lower cavity is pushed by an additional push rod to pass through the piston and enter the upper cavity to mix with the freeze-dried powder. The inventor found that the piston cannot effectively seal during reproduction. In the test, the problem of liquid leakage often occurs, i.e., the solvent enters the cavity for storing the freeze-dried drug before the use stage, and the existence of the double-cavity structure becomes meaningless at this time.

[0008] After analyzing and researching the defects in the prior art, the inventor has developed the following technical solution.

[0009] A double-cavity penicillin bottle for easy use includes a bottle cap, a rubber plug, and a bottle body. The A bottle cap part is provided with a bottle cap pull tag. The B rubber plug part is provided with a rubber plug stress point. The C bottle body (8) part is provided with a cavity A (3), a cavity B (7), and a separation layer (4). The D cavity A (3) and the cavity B (7) are separated by the separation layer (4).

[0010] In some embodiments, the partition layer (4) is provided with a movement stopper (41). The function of the movement stopper is to effectively prevent the double-cavity penicillin bottle from rolling when the double-cavity penicillin bottle is placed on a horizontal table and subjected to slight external force or the table is not horizontal.

The injection needle guide is hollow and in the shape of a truncated cone. When the injection needle enters the cavity, the inner wall of the injection needle guide guides the needle. Meanwhile, the injection needle guide is linked to the conical liquid collection site at the bottom of the cavity. When the needle enters the bottom of the cavity through the injection needle guide, the liquid collection site allows the complete absorption of the liquid without tilting the bottle or deliberately controlling the angle of the needle, thereby improving the convenience of use.

[0018] In some embodiments, the cavity B (7) is connected to the rubber plug B (6) and the bottle cap B (5).

[0019] In some embodiments, the rubber plug B (6) is provided with a rubber plug B stress point (61). The outer side of the rubber plug B (6) can be provided with threads or not. The rubber plug B (6) has the same structure as the rubber plug A (2), both of which have a rubber plug stress point. When the rubber plug is opened, the user can place their hand on the rubber plug stress point and pull it upwards to quickly open a gap, thereby connecting the cavity to the outside world and smoothly opening the rubber plug. The difference between the two is that the rubber plug B (6) is connected to the bottle cap B (5) and the cavity B (7), while the rubber plug A (2) is connected to the bottle cap A (1) and the cavity A (3).

[0020] In some embodiments, the bottle cap B (5) is provided with a bottle cap B pull tab (51); a bottle cap B pull tab upper end (511); a bottle cap B pull tab lower end (512); a bottle cap B pull tab hand contact surface (513); and a bottle cap B pull tab upper end tear path (515). The bottle cap B pull tab (51) is combined with the bottle cap B pull tab upper end tear path (515). When the user pinches the bottle cap B pull tab (51) to tear open the bottle cap B (5), the bottle cap B pull tab (51) moves along the bottle cap B pull tab pulling direction (514), and the bottle cap B pull tab upper end (511) moves along the bottle cap B pull tab upper end tear path (515). This makes the process of opening the bottle cap more labor-saving and convenient.

[0021] In some embodiments, the bottle cap B (5) has the same structure as the bottle cap A (1), both of which have a bottle cap pull tab in the shape of a triangle or a rectangle; a bottle cap pull tab upper end; a bottle cap pull tab lower end; a bottle cap pull tab hand contact surface; and a bottle cap pull tab upper end tear path. They have the same functions, and the difference between them is that the bottle cap B (5) is connected to the rubber plug B (6) and the cavity B (7), while the bottle cap A (1) is connected to the rubber plug A (2) and the cavity A (3).

[0022] In some embodiments, when the medical staff has used the drug liquid in a certain cavity, at this time the mass distribution of the double-cavity vial is uneven, when the medical staff places the double-cavity vial horizontally on the desktop or other placement site, if the desktop or other placement site has a large inclination, it is difficult to control the stability of the bottle body only by the movement stopper (41) in the double-cavity vial, therefore, through multiple tests, the inventors finally design the liquid collecting parts in the cavity A (3) and the cavity B (7), and the separation layer (4) to be solid structures as the movement stopper (41), and the four structures are associated with each other, so as to enhance the stability of the double-cavity vial in the foregoing or other harsh use environments.
