Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a bottle stopper puncture device for residual liquid medicine at the end of an infusion bag. Background Art
[0002] Infusion sets are the most commonly used medical consumables in clinical practice. After sterilization, they establish a channel between the vein and the liquid medicine and are used for intravenous infusion.
[0003] The infusion set is mainly composed of a skin puncture needle, an infusion tube and a bottle stopper puncture needle. There is a main infusion hole at the top of the bottle stopper puncture needle. During the drip operation, the bottle stopper puncture needle is first passed through the bottle stopper of the infusion bottle into the infusion bottle, and then the skin puncture needle is inserted into the patient's vein, so that the medicine in the infusion bottle slowly enters the patient's vein. Since the main infusion hole of the bottle stopper puncture needle is at the top of the needle, the medicine level cannot continue to flow into the infusion tube after it is lower than the main infusion hole, resulting in insufficient medication, especially the waste rate of precious medicine in small doses is even greater.

[0009] In order to prevent the puncture head from detaching from the bottle stopper, as a preferred bottle stopper puncture device for residual medicine at the end of the infusion bag of the utility model, the outer wall of the puncture head is fixedly connected to a limiting portion, the limiting portion is located above the multiple liquid inlet holes, and the cross-section of the limiting portion is an isosceles trapezoidal structure.
[0010] In order to limit the position of the puncture head, as a preferred embodiment of the utility model for a bottle stopper puncture device for residual liquid medicine at the end of an infusion bag, the diameter of the limiting piece is 1.5-2 times the diameter of the puncture head.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] The liquid inlet channel is in a spiral structure as a whole. The liquid medicine moves along the spiral path. The length of the spiral path is longer than that of the straight path. When the liquid medicine flows in the spiral tube, it must bypass the curves in the spiral channel in sequence, which will make the liquid medicine move faster, accelerate the flow of the liquid medicine, and make the liquid medicine introduced into the infusion tube smoother. At the same time, a plurality of evenly distributed liquid inlet holes are opened below the outer wall of the puncture head. The plurality of liquid inlet holes are located in the lower half of the puncture head as a whole, so that the liquid medicine with a liquid level lower than the liquid inlet port can smoothly enter the liquid inlet cavity, reduce the residual liquid in the infusion bottle, save the liquid medicine, and facilitate the treatment of patients.
[0013] The cross-section of the limiting part is an isosceles trapezoidal structure, which can be smoothly entered when puncturing the bottle stopper. After the limiting part enters the bottle body, the rubber bottle stopper shrinks and resets, thereby limiting the position through the limiting part to prevent the puncture head from being pulled out of the bottle body, making it safer and more reliable to use.
