Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a threaded bottle stopper puncture device. Background Art

[0002] A bottle stopper puncture device is a tool used to penetrate a bottle stopper and extract a sample therefrom. It is usually made of stainless steel or plastic and has a sharp needle that can easily penetrate a cork or plastic stopper to extract a liquid or gas sample from a sealed bottle for testing or analysis.

[0003] Each time the bottle stopper puncture device punctures an infusion bottle, the depth is inconsistent, or in order to reduce excessive residual liquid, the bottle stopper puncture device is pulled out, which may cause part of the puncture device to be exposed to the air and then enter the infusion bottle, resulting in contamination. For example, in the prior art, Chinese Patent Publication No. "CN210384535U" discloses a puncture device for facilitating bottle stopper puncture, including a protective cover. A fixing part is arranged at the lower end of the protective cover, a button is arranged at the lower end of the fixing part, a pull buckle is arranged at the lower end of the button, an infusion tube is arranged at the lower end of the pull buckle, a connecting part is arranged on one side of the button, an L-shaped component is arranged on one side of the connecting part, a top hook is arranged at the upper end of the L-shaped component, a retaining rod is arranged at the lower end of the L-shaped component, a push handle is arranged at the lower end of the retaining rod, a disposable needle is arranged inside the protective cover, a puncture-proof sleeve is arranged at the upper end of the disposable needle, and an upper buckle is arranged inside the fixing part. The utility model solves the problems that the traditional bottle stopper puncture device consumes a lot of effort when puncturing the bottle stopper and may accidentally injure oneself, and that the traditional bottle stopper puncture device generates glue chips when puncturing the bottle stopper, which has attracted wide attention.

[0004] In specific operations, the liquid inlet channel is arranged at the top of the puncture device, resulting in more residual liquid in the infusion bottle, causing waste of medicine and insufficient dosage for children. For traditional bottle stopper puncture devices, it is easy to generate debris when puncturing the rubber stopper, and the buckle and the puncture device cannot be reused, resulting in a relatively high overall replacement cost. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above-mentioned disadvantages of waste of liquid medicine and non-reusability between the buckle and the puncture device in the prior art, and to propose a threaded bottle stopper puncture device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] Design a threaded bottle stopper puncture device, including a tapered part and a connecting part. The tapered part is connected to the connecting part through a threaded part. An inlet channel and a ventilation channel are arranged inside the connecting part. The tapered part and the connecting part puncture a medicine bottle, so that the liquid medicine at the bottom of the medicine bottle enters the inlet channel through the threaded part;

[0008] Wherein, a stop baffle and a fixing member are provided at the bottom of the connecting portion. The fixing member is used to fix the connecting portion to prevent slippage, and the fixing member can be reused through an elastic structure.

[0009] Furthermore, the threaded member is an elastic structure, and it is spirally wound between the tapered portion and the connecting portion. A through hole communicating both ends is provided at the center of the threaded member, and this through hole is used to avoid the liquid inlet channel and the air exchange channel.

[0010] Furthermore, the fixing member is slidably connected to the bottom of the connecting portion through a middle mounting hole. Elastic bodies extending upward are provided at both ends of the fixing member, and clamping portions and pressing handles are respectively provided on the opposite sides and the back sides of the two elastic bodies.

[0011] Furthermore, the elastic structure includes deformation grooves. At least one convex structure is provided at the bottom of the connecting portion. A pair of the deformation grooves communicate with the mounting hole to form an elastic portion. The elastic portion slides in contact with the convex structure, and the fixing member is arranged between the stop baffle and the convex structure.

[0012] Furthermore, the medicine bottle is provided with a connection port at the bottle mouth. A circular portion protruding outward is provided around the connection port. The two elastic bodies are clamped to the circular portion through the clamping portions.

[0013] Furthermore, the stop baffle abuts against the connection port, and an air filter port communicating with the air exchange channel is provided below the stop baffle on the connecting portion.

[0014] For a threaded bottle stopper puncture device proposed by the present utility model, the beneficial effects are as follows: A threaded member is provided between the tapered portion and the connecting portion of the present utility model. The low-position opening of the thread is beneficial for more thorough infusion of the liquid medicine, reducing waste of the liquid medicine. The fixed position for each puncture is the bottom of the thread, avoiding liquid contamination. In addition, the thread design has a greater frictional force, and the cooperation with the fixing member makes it less likely for the connecting portion to slip off. Moreover, the fixing member and the connecting portion can be reused through an elastic structure. When replacing the puncture device, the fixing member can be disassembled, and the disassembled fixing member can be connected to a new puncture device for use, reducing the replacement cost.
