一种医疗设备能够用于常规血透时候的方便无痛的进入血管。

Hemaport是由Hemapure AB公司(Uppsala, Sweden)开发的无针头系统，作为血透患者因为解剖原因不能采用动静脉(AV)瘘的情况下，或者作为中央透析导管的替代选择。其原理是使用跨皮下钛移植物，不同于进入血管的方法。Hemaport和相关透析系统已经获得了CE标志。

系统的主要成分是氮化物钛针阀设备，手术植入合适的位置，通常是非主要的上肢或者腿，抛弃式盖子和涂药器。血液循环通过人工合成的移植片，形成流入动脉和受体静脉之间的终端-侧枝吻合。在位置上使用封闭板，血流从动脉向静脉持续流入移植物。在治疗之前，该封闭板可以换成透析盖。然后连接Hemaport，通过血导管连接到透析机器之上。当透析治疗结束的时候，透析盖再换成新的封闭盘。

 
Circulation Implant Offers Needle-Free Dialysis
 
 
A medical device has been developed that allows simple and painless access to blood circulation in patients undergoing regular hemodialysis.

The Hemaport, developed by Hemapure AB (Uppsala, Sweden), is a needle-free system developed as an option for patients undergoing dialysis when arteriovenus (AV) fistulas are failing for anatomic reasons or as an alternative to central dialysis catheters. The concept is based on a transcutaneous titanium implant and is a fundamentally different approach to solving problems associated with vascular access. Hemaport and its associated dialysis set have received the CE Mark.

The main components of the system are a nitrided titanium housing device, surgically implanted at a suitable location--usually the non-dominant upper arm or a leg--and disposable lids and applicators. Blood is circulated to the housing through synthetic grafts, forming end-to-side anastomoses on the inflow artery and the recipient vein. With a sealing plate in position, blood is continuously flowing through the implant, from artery to vein. Prior to treatment, the sealing plate is exchanged with a dialysis lid. The Hemaport is then connected, via the blood

tubing, to the dialysis machine. When the dialysis treatment is finished, the dialysis lid is exchanged for a new

sealing plate.
