Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. Furthermore, the technical features mentioned in the embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

Fig. 1 is a top view of the medical bottle stopper provided by the embodiment of the present invention, as shown in fig. 1, the medical bottle stopper includes a plug ring 1 and a bottle cap 2, the plug ring 1 and the bottle cap 2 are elastic structural members, one end of the plug ring 1 is coaxially fixed on one end surface of the bottle cap 2, and the outer diameter of the bottle cap 2 is greater than the outer diameter of the plug ring 1.

Fig. 2 is a cross-sectional view of a medical bottle plug that embodiment provided, as shown in fig. 2, a plurality of helicla flutes 11 and a plurality of bar groove 12 have on the inner wall of cock ring 1, the one end of each helicla flute 11 extends to the terminal surface of the other end of cock ring 1, the other end of helicla flute 11 extends to bottle lid 2, a plurality of bar grooves 12 are arranged along the inner wall circumference interval of cock ring 1, the axis of each bar groove 12 is all on a parallel with the axis of cock ring 1, the one end of each bar groove 12 extends to the terminal surface of the other end of cock ring 1, the other end and a helicla flute 11 intercommunication of each bar groove 12.

To the utility model provides a pair of medical bottle plug, when the medicine bottle inversion infusion was to a small amount, the partial albumin of gathering on the terminal surface of cock ring 1 can be through a plurality of helicla flutes 11 by the top water conservancy diversion of cock ring 1 to the bottom of cock ring 1, and can increase the speed that albumin flows through helical structure, avoids albumin to remain on cock ring 1 terminal surface and can't flow in to cock ring 1 and used.

Further, a plurality of bar-shaped grooves 12 can also guide part of albumin gathered on the end face of the plug ring 1 to the corresponding spiral groove 11, and finally realize that the residual albumin is led to the bottom of the plug ring 1 through the structure of the spiral groove 11, so that the suction of most albumin can be finally realized through the syringe, and the waste of albumin is avoided.

That is to say, the utility model provides a medical bottle stopper can make the gathering go up (the top of fig. 2) albumin smoothly flows in to the bottom of cock ring 1 on the terminal surface of cock ring 1 through a plurality of helicla flutes 11 and a plurality of bar groove 12 to the suction of injection, thereby can effectively avoid the waste of albumin.

In this embodiment, the number of the strip-shaped grooves 12 can be 4, and 4 strip-shaped grooves 12 are uniformly arranged at intervals along the inside of the stopper ring 1.

In other embodiments of the present disclosure, the number of the strip-shaped grooves 12 may also be 6 or 8, which is not limited by the present invention.

Referring again to fig. 2, in the present embodiment, the included angle α formed between the helical groove 11 and the radial direction of the stopper ring 1 is 30-60 °.
