Description

Technical Field

[0001] The utility model belongs to the technical field of disposable medical devices, in particular to a novel bottle stopper piercer. Background Art

[0002] As the market's risk control of medical devices becomes increasingly stringent, product usage requirements are correspondingly increased. Traditional vial piercers have excessive piercing force, which easily generates debris during the process. In addition, the product has a high defective rate and low production efficiency during actual production. Traditional vial piercers lack protective devices, which causes users to accidentally drag the dropper and pull the vial piercer out of the vial. Utility Model Content

[0003] The utility model provides a novel bottle stopper piercer to solve the problems raised in the above background technology.

[0004] To achieve the above purpose, the specific technical solution is as follows:

[0005] A novel bottle stopper piercer comprises a lower base, an upper base is fixedly mounted on the lower base, a bottle stopper piercer is fixedly mounted on the upper base, and the bottle stopper piercer is connected through the lower base and the upper base.

[0006] Furthermore, an upper sheath and barbs are fixedly mounted on the outer wall of the lower base, and the barbs are four in a circular array.

[0007] Furthermore, the bottle stopper is pierced through to form an air inlet and a liquid inlet.

[0008] Furthermore, a filter element is fixedly installed on the inner wall of the liquid inlet hole.

[0009] Furthermore, an air intake seat is provided through one side of the upper base.

[0010] Furthermore, a drip bucket is provided at the bottom of the lower base.

[0011] Compared with the prior art, the beneficial effects of the utility model are at least as follows: the puncture site is optimized to optimize the original three-hole liquid inlet into one-hole liquid inlet, the puncture is reduced while reducing the burr generation point, it is easy to inject and only needs to develop a pair of molds to solve the problem, the accessory structure is simple and easy to inject, the defective rate is low during the production process, and the injection efficiency can be effectively improved. Ultimately, the risk of infusion is reduced, the production cost is reduced, and the provision of barbs can prevent the user from accidentally dragging the dropper and causing the bottle cork piercer to pull out the bottle cork to a certain extent.

[0015] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0016] like Figure 1-2 As shown, a new type of bottle stopper piercer includes a lower base 1, an upper base 2 is fixedly mounted on the lower base 1, a bottle stopper piercing device 3 is fixedly mounted on the upper base 2, the bottle stopper piercing device 3 is connected through the lower base 1 and the upper base 2, and the top of the bottle stopper piercing device 3 is designed to be in the shape of a spike to facilitate piercing the bottle stopper.

[0017] Specifically, an upper sheath 4 and barbs 5 are fixedly mounted on the outer wall of the lower base 1. The barbs 5 are four in a circular array. The barbs 5 are provided to prevent the user from dragging the dropper with his hands during use, causing the bottle stopper piercer 3 to be pulled out of the bottle stopper.

[0018] Specifically, the bottle stopper piercing hole 3 is penetrated to form an air inlet 6 and a liquid inlet 7.

[0019] Specifically, a filter element 8 is fixedly installed on the inner wall of the liquid inlet hole 7, and the filter element 8 is provided to prevent tiny debris in the liquid medicine from flowing into the human body.

[0020] Specifically, an air inlet seat 9 is provided through one side of the upper base 2 .

[0021] Specifically, a drip bucket 10 is provided at the bottom of the lower base 1 .

[0022] The working principle and use process of the utility model are as follows: when in use, the bottle stopper piercing 3 is penetrated through the bottle stopper, and the air inlet pipe is installed through the air inlet seat 9. The puncture position is optimized from the original three-hole liquid inlet to a single-hole liquid inlet, and the puncture is reduced while the burr generation point is reduced, which is convenient for injection molding and only requires the development of one mold. At the same time, by setting the barbs, it can be avoided to a certain extent that the user accidentally drags the dropper, causing the bottle stopper to be punctured and pulled out of the bottle stopper.

[0023] It should be understood that although the present specification is described according to embodiments, not every embodiment contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0024] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
