One end of the capsule has an integrally formed bottom post, and the two opposite sides of the bottom post have wings for welding to an infusion bag or for holding. The capsule has a cavity for storing drugs inside. The cavity is open at both ends. One end of the open end has a sealing diaphragm, which can be ruptured by squeezing the capsule. The sealing plug is located at the other end of the open end. When oral administration or infusion is required, a steel needle or plastic needle can be inserted into the cavity through the sealing plug.

[0006] Optionally, the end face of the sealing plug is provided with an easy-tear film.

[0007] Optionally, the sealing diaphragm is welded to the end face of the bottom post, and the end face of the bottom post is provided with a plurality of raised welding points.

[0008] Optionally, the wing edge has a porous, hollowed-out structure.

[0009] Optionally, the sealing plug is provided with an anti-detachment structure at the contact point with the bladder body.

[0010] Optionally, the anti-detachment structure consists of mating external and internal threads.

[0011] Optionally, the surface of the capsule is provided with an anti-slip structure.

[0012] Optionally, the anti-slip structure is a plurality of annular grooves spaced apart along the length of the bladder body.

[0013] Optionally, the capsule and the sealing plug are integrally injection molded from two different materials.

[0014] Optionally, the capsule is made of PP material and the sealing plug is made of TPE material.

[0015] The technical solution of this utility model has at least the following advantages and beneficial effects: In this utility model, the cavity inside the capsule can store drugs; the provided wings can be welded to the infusion bag, and can also be easily held for direct oral administration or mixed with liquid for oral administration; the provided sealing diaphragm can be ruptured by squeezing the capsule to obtain the internal drugs; the provided sealing plug allows steel or plastic needles to be inserted into the cavity when oral administration or infusion is required; it can be seen that the interface provided by this utility model can be used as an infusion accessory for welding to the infusion bag, and can also be used as an oral drug container, making the interface functionally diverse and reducing packaging material waste.

[0020] refer to Figures 1-3 A multifunctional drug container interface is designed to be used both as an infusion accessory for welding to infusion bags and as an oral medication container, thereby increasing its versatility and reducing packaging waste.

[0021] The multifunctional drug container interface includes a capsule body 1 and a sealing plug 2. The surface of the capsule body 1 is provided with an anti-slip structure 104 to increase friction and improve ease of handling or gripping with a device. Alternatively, in this embodiment, the anti-slip structure 104 is a plurality of annular grooves spaced apart along the length of the capsule body 1. In other embodiments, the anti-slip structure 104 can of course be other forms, such as stripes spaced apart along the circumferential direction.

[0022] One end of the capsule 1 is provided with an integrally formed bottom post 101 as a structural support to ensure the structural stability of the capsule 1. The inside of the capsule 1 has a cavity 103 for storing drugs. Both ends of the cavity 103 are open, and a sealing diaphragm (not shown) is provided at one end of the open end. The sealing diaphragm serves as the encapsulation port and opening port for the drug. A high-barrier film is selected. During use, the sealing diaphragm can be ruptured by squeezing the capsule 1, thereby obtaining the drug inside.

[0023] In this embodiment, the sealing diaphragm is welded to the end face of the bottom post 101. On this basis, the end face of the bottom post 101 is provided with a number of protruding welding points 1011.

[0024] The bottom post 101 has wings 102 on two opposite sides. The wings 102 are used for welding to the infusion bag or for holding. When the interface is used as an independent oral medication container, its function is to make it easy to use. The patient can hold the two wings and take the medication directly or mix it with liquid before taking it. When used as an infusion accessory, its function is to weld to the infusion bag. Furthermore, the wings 102 have a porous and hollow structure and are relatively thin, so they can be fused with the membrane material, which increases the efficiency of welding the infusion bag and reduces the welding difficulty and the risk of leakage at the welding point 1011.

[0025] The sealing plug 2 is located at the open end of the capsule 1. When oral or intravenous administration is required, a steel or plastic needle can be inserted into the cavity 103 through the sealing plug 2, and the sealing plug 2 can still provide a good seal after the needle is removed. In this embodiment, the capsule 1 and the sealing plug 2 are integrally injection molded from two different materials, avoiding subsequent assembly steps and ensuring sealing performance and cleanliness. Alternatively, the capsule 1 can be made of PP material, and the sealing plug 2 can be made of TPE material.

[0026] An anti-detachment structure 3 is provided at the contact point between the sealing plug 2 and the bladder body 1 to improve the bonding strength between the sealing plug 2 and the bladder body 1. Alternatively, in this embodiment, the anti-detachment structure 3 consists of mating external and internal threads. Taking the bladder body 1 being injection molded first and then the sealing plug 2 being injection molded as an example, the internal thread is formed during the injection molding of the bladder body 1, and the mating external thread is formed during the injection molding of the sealing plug 2. In other embodiments, the anti-detachment structure 3 can of course take other forms, such as an annular groove on the bladder body 1 and a mating boss on the sealing plug 2.

[0027] The end face of the sealing plug 2 is provided with an easy-tear film (not shown in the figure). The easy-tear film serves as an auxiliary protective seal to prevent contamination of the end face of the sealing plug 2. Those skilled in the art should understand that easy-tear film is a functional packaging material that is easy to tear off, also known as easy-open film, easy-peel film, easy-tear film, etc.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
