The utility model relates to the field of medical devices for assisted reproductive technology, in particular to an artificial insemination and transplantation tube. The implantation catheter comprises a soft and flexible transplantation catheter and a syringe connector fixed to the end of the transplantation catheter. The transplantation catheter is provided with a locator which can slide along the axis of the transplantation catheter. The front end of the transplantation catheter is spherical structure, and several sperm release holes are evenly arranged on the front side wall of the transplantation catheter. The transplantation catheter of the utility model is soft and elastic, and can connect the syringe through the syringe joint, and inject the treated semen into the uterine cavity through the cervical orifice to realize artificial insemination. At the same time, the locator can move freely along the axis of the implanted catheter, which can be used to control the insertion of the catheter according to the uterine depth measured previously. In addition, the top of the transplantation catheter is spherical structure, which does not damage the soft tissue. There are several sperm release holes on the top side, which is conducive to multi-point sperm injection and multiple fertilization.
【技术实现步骤摘要】
一种人工授精移植管
本技术涉及辅助生殖技术用医疗器械领域,具体地说,涉及一种人工授精移植管。
技术介绍
人工授精是指采用非性交的方式将精子递送到女性生殖道中以达到使女子受孕目的的一种辅助生殖技术。人工授精移植管是人工授精术中必用器具,用于将精子移植到女性生殖道中。传统人工授精移植管的缺点在于:不仅质地硬,而且进行体外人工授精时,无法确定授移植管注入子宫的深度,同时,其顶端侧壁上只有一个开孔,不利于精液的多点注入和多处授精。
技术实现思路
本技术的目的在于,提供一种人工授精移植管,以解决上述的技术问题。为实现上述目的,本技术所采用的技术方案是:一种人工授精移植管,其特征在于:包括软质且富有弹性的移植导管和固定连接在移植导管末端上的注射器接头,所述移植导管上套有可沿移植导管轴向滑动的定位器;所述移植导管的前端为球面结构,且在其前端侧壁上均匀设置若干个精子释放孔。优选的:其整体长度为135-145mm。优选的:所述移植导管为无色聚乙烯管,其长度为110-115mm,外径为1.30-1.35mm,内径为0.35-0.65mm。优选的:所述注射器接头的长度为25-28mm。有益效果 ...
