Abstract
一种单轨式微导管腔内注射装置，由一个双腔导管构成，一个为注射腔，其尾端固定连接有一个注射器连接头。另一个为支撑及导丝腔，其后段为支撑腔，支撑腔内设置有支撑钢丝，前段为导丝腔，导丝腔的管壁上设置有一个导丝出口孔，导丝出口孔位于支撑钢丝的前端面的前方，导丝腔的前端开口于导管的最前端，导丝腔用于穿过导丝，沿导丝将导管引导到手术部位的血管腔内，便于精细的手术操作。将注射器与注射器连接头连接，将药物通过注射腔注入。导管外壁上的位置标记刻度可以帮助判断注射腔的前端位置。导管直径小，免除了撤退导丝的操作，导管的外壁上覆盖有润滑涂层，可以减少导管推送时的阻力，便于深入次级血管，手术过程简单。
A single-track microcatheter intracavitary injection device is composed of a double-cavity catheter, one of which is an injection cavity, and a syringe connector is fixedly connected to its tail end. The other is the support and guide wire chamber, the back part is the support chamber, the support steel wire is arranged in the support chamber, the front part is the guide wire chamber, and a guide wire outlet hole is arranged on the tube wall of the guide wire chamber, and the guide wire outlet hole is located at In front of the front end of the support wire, the front end of the guide wire lumen is opened at the front end of the catheter. The guide wire lumen is used to pass through the guide wire and guide the catheter into the vascular cavity of the surgical site along the guide wire to facilitate fine surgical operations. Connect the syringe to the syringe connector, and inject the drug through the injection cavity. The position marking scale on the outer wall of the catheter can help to judge the front end position of the injection cavity. The diameter of the catheter is small, which eliminates the need to withdraw the guide wire. The outer wall of the catheter is covered with a lubricating coating, which can reduce the resistance when the catheter is pushed, and facilitate deep penetration into secondary blood vessels. The operation process is simple.
Description
技术领域：Technical field:
本实用新型涉及机械领域，尤其涉及液体输送装置，特别涉及穿过皮肤向血管内输送药物的医用注射装置，具体地是一种单轨式微导管腔内注射装置。The utility model relates to the field of machinery, in particular to a liquid delivery device, in particular to a medical injection device for delivering medicine into a blood vessel through the skin, in particular to a single-track microcatheter intracavitary injection device.
背景技术：Background technique:
临床医学中，经常需要进行介入血管腔内的治疗手术。现有技术中，采用“Over-the-wire”式球囊或微导管或者经皮腔内的血栓抽吸装置来实现上述治疗。“Over-the-wire”式球囊或微导管由一个导管构成，导管中设置有一个腔体，在腔体中可通过导丝，利用导丝可将导管头引导至血管腔内手术部位，但是，在利用注射器从导管的另一端注入药物及造影剂之前，需要先撤出导丝，导致手术过程复杂。而经皮腔内的血栓抽吸装置由一个导管构成，导管中并行设置有一个导丝腔和一个抽吸腔，导丝腔中可通过导丝，可以利用导丝将导管头引导至血管腔内手术部位，然后在导管的另一端通过抽吸腔注入药物及造影剂，由于内血栓抽吸装置原用于抽吸血栓，为了保证抽吸的效率，抽吸腔需要维持较大的直径，因此，导管的外径较大，不宜深入次级血管。In clinical medicine, it is often necessary to perform therapeutic operations involving intravascular intervention. In the prior art, "Over-the-wire" balloons or microcatheters or percutaneous intraluminal thrombus aspiration devices are used to achieve the above treatments. The "Over-the-wire" balloon or microcatheter is composed of a catheter, and a cavity is provided in the catheter, and a guide wire can pass through the cavity, and the guide wire can be used to guide the catheter tip to the intravascular surgical site, However, before using a syringe to inject drugs and contrast media from the other end of the catheter, the guide wire needs to be withdrawn first, making the surgical procedure complicated. The thrombus suction device in the percutaneous cavity is composed of a catheter. A guide wire lumen and a suction lumen are arranged in parallel in the catheter. The guide wire can pass through the guide wire, and the guide wire can be used to guide the catheter head to the vascular cavity. The internal surgical site, and then inject drugs and contrast agents through the suction cavity at the other end of the catheter. Since the internal thrombus suction device was originally used to suck thrombus, in order to ensure the efficiency of suction, the suction cavity needs to maintain a larger diameter. Therefore, the outer diameter of the catheter is relatively large, and it is not suitable to penetrate into secondary blood vessels.
