Description

Technical Field

[0001] The utility model relates to the technical field of medical device, in particular to a polyisoprene gasket for improving the risk of invagination. Background Art

[0002] Polyisoprene gaskets are commonly used to seal the mouths of infusion bottles and medicine bottles, enabling long-term medication storage. However, some polyisoprene gaskets have been found to collapse when used on infusion bottles and medicine bottles. This can easily cause the surrounding seal to warp, leading to air or moisture entering the infusion bottle or medicine bottle, and in severe cases, causing the medication to expire or become ineffective. Furthermore, when polyisoprene gaskets collapse, medical personnel face significant resistance when inserting a needle, making it difficult to penetrate the gasket.

[0003] Therefore, it is necessary to design a new gasket structure that can improve the indentation of the polyisoprene gasket. Utility Model Content

[0004] In order to solve the above problems, the present invention proposes a polyisoprene gasket that improves the risk of invagination.

[0005] A polyisoprene gasket for improving the risk of invagination includes an inner cover wrapped around the bottle mouth of a medical bottle and an outer cover tightly fitted with the inner cover. A rubber head is provided at the center of the outer cover to facilitate needle insertion, and an anti-invasion component that cooperates with the inner cover is provided on the rubber head.

[0006] Furthermore, the vertical cross-sectional structural shape of the inner cover is set to be C-shaped so as to wrap around the inner side wall and the outer side wall at the bottle mouth of the medical bottle.

[0007] Furthermore, the anti-sinking component includes a pressing portion that is arranged on the outer cylindrical surface of the rubber head and is evenly distributed. The pressing portion is located on the inner side of the outer cover and rests on the inner cover.

[0008] Furthermore, a raised portion protruding toward the central axis of the inner cover is provided on the inner cover near the lower side of the inner side wall of the inner cover, and the lower end of the pressing portion abuts against the raised portion to prevent the rubber head from moving downward.

[0009] The beneficial effects of the present invention are as follows: the present invention effectively improves the phenomenon of collapse by pressing the pressing part of the anti-collapse component against the inner cover, and at the same time makes the medical bottle air-proof, thereby ensuring the safety of drug use, making it convenient to insert a needle, and reducing drug waste.

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below.

[0015] like Figure 1 and Figure 2 As shown, a polyisoprene gasket for improving the risk of invagination includes an inner cover 2 wrapped around the bottle mouth of a medical bottle 1, an outer cover 3 tightly fitted with the inner cover 2, a rubber head 4 for easy insertion of a needle is provided at the center of the outer cover 3, and an anti-invagination component cooperating with the inner cover 2 is provided on the rubber head 4.

[0016] The present invention features a rubber tip 4 that facilitates needle insertion. Furthermore, the anti-sinking assembly prevents the upper portion of the outer cover 3 and the rubber tip 4 from sinking inward, providing support from the inside and effectively addressing the issue of indentation in polyisoprene gaskets in the prior art. The inner cover 2, outer cover 3, and anti-sinking assembly are all made of polyisoprene.

[0017] like Figure 1 As shown, the vertical cross-sectional structural shape of the inner cover 2 is set to be C-shaped so as to wrap the inner wall and outer wall at the bottle mouth of the medical bottle 1. Such a structural design can achieve good wrapping performance for the medical bottle 1.

[0018] Specifically, such as Figure 1 As shown, the anti-sinking assembly includes a pressing portion 5 that is evenly distributed and arranged on the outer cylindrical surface of the rubber head 4 . The pressing portion 5 is located on the inner side of the outer cover 3 and rests on the inner cover 2 .

[0019] As a further optimization of the present invention, a raised portion 6 is provided on the inner cover 2 of the present invention, which is close to the inner side wall of the inner cover 2 and protrudes toward the central axis of the inner cover 2. The lower end of the pressing portion 5 abuts against the raised portion 6 to prevent the rubber head 4 and the outer cover 3 from moving along the inner cover 2. Figure 1Furthermore, the abutting structure design, i.e., the pressing portion 5 generates an outward thrust on the protrusion 6, which enables the C-shaped structure of the inner cap 2 to fit tightly against the medical bottle 1, thereby improving the sealing performance and preventing the inner cap 2 from falling off the medical bottle 1.

[0020] The raised portion 6 is a full circle in the horizontal direction. Of course, the raised portion 6 of the present invention can also be a multi-section distributed structure in the horizontal direction, as long as it can ensure that the lower end of the pressing portion 5 can fully rest against the raised portion 6.

[0021] Specifically, the vertical cross-sectional structure of the raised portion 6 is semicircular. Of course, other shapes and models that can resist the pressing portion 5 can also be applied to the present invention, that is, the vertical cross-sectional structure of the raised portion 6 of the present invention is not limited to semicircular.

[0022] Specifically, the pressing portion 5 is cylindrical or square.

[0023] Specifically, the pressing parts 5 are provided in three or more groups, and the number can be customized according to the size requirements of the medical bottle 1 .

[0024] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
