本发明涉及一种动脉鞘，尤其涉及一种带有残液收集的动脉鞘。The invention relates to an arterial sheath, in particular to an arterial sheath with raffinate collection.
背景技术Background technique
动脉鞘是一种重要的医疗器具，用于置入动脉中，进行灌液、导流或者穿线等造作。The arterial sheath is an important medical device, used to be placed in the artery for irrigation, drainage or threading.
动脉鞘一般包括内芯、鞘管、鞘管接头、三通阀，鞘管接头安装在鞘管的后端，鞘管接头通过导管与三通阀连接，内芯穿过鞘管接头并处于鞘管中，其中三通阀用于灌液。The arterial sheath generally includes an inner core, a sheath tube, a sheath tube joint, and a three-way valve. The sheath tube joint is installed at the rear end of the sheath tube, and the sheath tube joint is connected to the three-way valve through a catheter. In the pipe, the three-way valve is used for filling liquid.
上述的动脉鞘在抽出内芯时，由于抽出后在鞘管中形成负压，患者的血液或其他液体会随内芯的抽出而从鞘管的后端流出，对患者身体的其他部位、手术台、地面等造成污染。When the above-mentioned arterial sheath is drawn out of the inner core, due to the negative pressure formed in the sheath tube after being drawn out, the patient's blood or other liquids will flow out from the rear end of the sheath tube with the extraction of the inner core, which will affect other parts of the patient's body, surgery, etc. Taiwan, ground, etc. cause pollution.
有人想到在鞘管的后端连接一个废液收集袋，用于收集从患者身上流出的血液或其他液体，但是无法处理好鞘管与废液收集袋之间的导流问题，血液或其他液体依然会四处乱流，效果很不理想，无法达到血液或其他液体收集的目的，这种做法根本不行，无法得到推广应用。Some people thought of connecting a waste fluid collection bag at the back end of the sheath to collect blood or other fluids flowing out of the patient, but the problem of diversion between the sheath and the waste fluid collection bag could not be handled well, blood or other fluids It will still flow around, the effect is very unsatisfactory, and the purpose of collecting blood or other liquids cannot be achieved. This method is not feasible at all and cannot be popularized and applied.
目前，各医务工作者都致力这方面的研究，但依然没有较好的解决办法。At present, all medical workers are devoting themselves to research in this area, but there is still no better solution.
