Description

Technical Field

[0001] This utility model relates to the field of medical rubber stopper technology, and in particular to a medical rubber stopper with built-in support to prevent deformation. Background Technology

[0002] In the medical field, medical rubber stoppers are widely used in containers such as medicine packaging bottles and infusion bottles to seal containers, prevent medicines and liquids from being contaminated by external factors, and ensure stable pressure inside the container. During use, such as during puncture or removal, the rubber stopper may deform due to uneven stress, affecting the smooth progress of the operation and even causing rubber fragments to fall into the container and contaminate the medicine or liquid. There are some technologies that improve the performance of rubber stoppers by improving their material or surface structure, but there is little research and improvement on the internal support structure of rubber stoppers, making it difficult to fundamentally solve the problem of rubber stopper deformation. Therefore, we propose a medical rubber stopper with built-in support to prevent deformation. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a medical rubber stopper with built-in support to prevent deformation. This invention solves the problem that during use, such as punctures or removal, the rubber stopper may deform due to uneven stress, affecting the smooth progress of the operation and potentially causing rubber fragments to fall into the container and contaminate the medicine or liquid.

[0004] This utility model discloses a built-in support anti-deformation medical rubber plug, including a cover plate, a sealing block at the lower center of the cover plate, a placement groove at the upper center of the cover plate, an installation groove below the placement groove of the sealing block, a fixing plate inside the placement groove, a fixing block matching the installation groove at the lower center of the fixing plate, a base plate below the fixing block, four connecting plates arranged in a matrix above the base plate, a first limiting groove matching the connecting plates on the fixing blocks, a fixing ring fixedly connected above the four connecting plates, and a second limiting groove matching the fixing ring on the fixing blocks.

[0005] In the above scheme, a plurality of positioning rods are arranged in a matrix above the base plate, and positioning holes matching the positioning rods are opened on the fixing block.

[0006] In the above scheme, a pull block is provided in the middle of the upper part of the fixing plate, and a through hole is provided in the middle of the upper end of the pull block.

[0007] In the above scheme, the sealing block is provided with multiple equidistant inner annular expansion ribs in the mounting groove.

The fixing plate 5 and the fixing block 6 can be inserted into the placement groove 3 and the installation groove 4. A base plate 7 is provided below the fixing block 6, and four connecting plates 8 arranged in a matrix are provided above the base plate 7. A first limiting groove 9 matching the connecting plate 8 is provided on the fixing block 6. The connecting plate 8 is fixedly connected to the fixing ring 10. The base plate 7, the connecting plate 8, and the fixing ring 10 constitute the internal support structure of the rubber plug.

The fixing block 6 is provided with a second limiting groove 11 that matches the fixing ring 10. The connecting plate 8 is engaged in the first limiting groove 9, and the fixing ring 10 is engaged in the second limiting groove 11. Through the mutual cooperation between the connecting plate 8 and the first limiting groove 9, and the mutual cooperation between the fixing ring 10 and the second limiting groove 11, the support structure can be stably installed on the fixing block 6.

[0019] The base plate 7 is provided with a plurality of positioning rods 12 arranged in a matrix. The fixing block 6 is provided with positioning holes 13 that match the positioning rods 12.
