[0045] Example 1

[0046] Combination Figure 1-Figure 3 For explanation, this embodiment provides a combined cover, including an outer cover and an inner cover arranged inside the outer cover; the outer cover includes a lower outer cover 2 and an upper outer cover 1 movably buckled on the lower outer cover 2, a pull ring 11 is provided at the top of the upper outer cover 1, and the lower outer cover 2 is a barrel-shaped structure; the inner cover includes an upper inner cover 3, a support portion 4 and a lower inner cover 5, the upper inner cover 3 is arranged inside the upper outer cover 1 and is located above the lower outer cover 2, one end of the support portion 4 is connected to the lower end surface of the upper inner cover 3, and the other end is connected to the upper end surface of the lower inner cover 5, and the lower inner cover 5 is arranged inside the lower outer cover 2 and is located at the bottom. It also includes a sealing gasket 7 arranged between the upper outer cover 1 and the upper inner cover 3 and an infusion container covering end 21 arranged at the bottom end of the lower outer cover 2.

[0047] A cavity for storing medicine is formed by the cooperation of the upper inner cover 3, the support part 4, the lower inner cover 5 and the outer cover. The upper outer cover 1 can move along the lower outer cover 2. When in use, when the upper outer cover 1 moves toward the lower outer cover 2, it will push the sealing gasket 7 set in the upper outer cover 1 to move. The sealing gasket 7 pushes the upper inner cover 3 to move, so that the support part 4 moves downward and pushes the lower inner cover 5 to move away from the lower outer cover 2. At this time, the medicine stored in the cavity falls from between the lower inner cover 5 and the lower outer cover 2 into the container body connected to the sheathing end 21 of the infusion container.

[0048] The sealing gasket 7 isolates and seals the inner cover and the outer cover, and the sealing gasket 7 can be made of rubber.

[0049] This embodiment can effectively separate the drug and the solvent, and the cavity is a closed space, which improves the safety and stability of drug storage and facilitates storage and transportation. It solves the technical problems in the prior art that the stability is reduced due to the pre-configuration of the drug, it is difficult to store it for a long time, and the drug solution is easily contaminated due to the injection of the drug alone.

[0050] There is no restriction on the material and size of the combined cover. For example, the material of the combined cover may be plastic, and the size may be determined according to actual application requirements.

[0051] In order to prevent the lower inner cover 5 from falling and affecting the infusion process, a plurality of tear strips 51 are provided around the lower inner cover 5, and one end of the tear strip 51 away from the lower inner cover 5 is connected to the inner wall of the lower outer cover 2. When the cavity is in the storage state, the plurality of tear strips 51 are in close contact with each other. When in use, when the upper outer cover 1 pushes the lower inner cover 5 downward to separate from the lower outer cover 2, the tear strips 51 are stretched, and gaps are formed between the plurality of tear strips for the passage of drugs or liquids.

[0052] Furthermore, the inner wall of the upper outer cover 1 is provided with an internal thread, and the outer wall of the lower outer cover 2 is provided with an external thread matching the internal thread on the inner wall of the upper outer cover 1. The upper outer cover 1 is movably buckled on the lower outer cover 2 through a threaded connection, and the upper outer cover 1 can move up and down along the outer wall of the lower outer cover 2.

[0053] Furthermore, it also includes a lock buckle 6 sleeved on the lower outer cover 2, and the lock buckle 6 is located at the lower end of the upper outer cover 1. The relative position between the upper outer cover 1 and the lower outer cover 2 is fixed by the lock buckle 6, and an external force is applied to cause displacement between the upper outer cover 1 and the lower outer cover 2. The lock buckle 6 is provided with a lock buckle puller 61, and the lock buckle 6 is separated from the upper outer cover 1 and detached from the lower outer cover 2 by the lock buckle puller 61.

[0054] Furthermore, the height of the support portion 4 is higher than the height of the lower outer cover 2 , and the difference between the height of the support portion 4 and the height of the lower outer cover 2 is greater than the length of the tear strip 51 .

[0055] It is ensured that the distance that the support portion 4 moves downward is sufficient to stretch the tear strips 51 until gaps appear between adjacent tear strips 51 .

[0056] Furthermore, the support portion 4 is a columnar structure and is coaxially arranged with the upper outer cover 1 . The coaxial arrangement can better transfer the thrust from the upper outer cover 1 to the lower inner cover 5 .

[0057] Furthermore, a tear cover 12 is provided on the upper outer cover 1, and a pull ring 11 is provided on the tear cover 12. The tear cover 12 is removed from the upper outer cover 1 through the pull ring 11 to expose the sealing gasket 7 for easy insertion of the infusion needle. In order to prevent the support part 4 from affecting the insertion of the infusion needle, positioning points can be provided on the sealing gasket 7 around the support part to guide the insertion of the infusion needle.

[0058] Example 2

[0059] Combination Figure 4-Figure 8To illustrate, this embodiment provides an infusion container, including a container body 8 and a combined cover provided in Embodiment 1, an interface 81 is provided on the container body 8, the outer wall of the interface 81 is sealed and connected to the inner wall of the infusion container covering end 21, and the inner diameter of the interface 81 is greater than or equal to the outer diameter of the lower inner cover 5. It is convenient for the upper outer cover 1 to push the lower inner cover 5 downward to separate from the lower outer cover 2. As the lower inner cover 5 gradually moves away from the lower outer cover 2, the tear strip 51 is stretched, and gaps appear between adjacent tear strips 51. The medicine in the cavity falls out of the gap into the container body 8 and is evenly mixed with the medicine in the container body 8. When using, the infusion container needs to be inverted, and the tear cover 12 is removed from the upper outer cover 1 through the pull ring 11, and the infusion needle is inserted from the positioning point on the sealing pad 7 corresponding to the tear cover 12.

[0060] Specifically, when the infusion container provided in this embodiment is in use, the lock 6 is separated from the upper outer cover 1 and detached from the lower outer cover 2 by the lock puller 61. The upper outer cover 1 is rotated to move along the outer wall of the lower outer cover 2 toward the container body, and the sealing gasket 7 disposed in the upper outer cover 1 is pushed to move. The sealing gasket 7 pushes the upper inner cover 3 to move, so that the support portion 4 pushes the lower inner cover 5 to move away from the lower outer cover 2, and the tear strip 51 is stretched, and gaps are formed between the tear strips. After the medicine stored in the cavity enters the container body and is evenly mixed with the liquid in the container body, the tear cover 12 is removed from the upper outer cover 1 by the pull ring 11, and the infusion needle is inserted from the positioning point on the sealing gasket 7.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
