压力导管和引导线组件
摘要：
一种用于测量活体血压的导管和引导线组件(10)，包括：具有远端端部和近端端部的近端管(11)；具有远端端部和近端端部的远端管(12)，远端管(12)的近端端部连接到近端管(11)的远端端部；具有远端端部和近端端部的流体可渗透线圈(13)，流体可渗透线圈(13)的近端端部连接到远端管(12)的远端端部；远端端头(14)，流体可渗透线圈(13)的远端端部固定在该远端端头中；以及芯线(16)，其附接在近端管(11)中，并且延伸穿过近端管(11)的一部分、远端管(12)和流体可渗透线圈(13)，并且固定在远端端头(14)中，其中近端管(11)的远端端部和远端管(12)的近端端部通过对接接头连接，并且其中芯线(16)在对接接头处或靠近对接接头处粘合或钎焊到近端管(11)的内壁。
摘要（英）：

A catheter and guide wire assembly (10) for measurement of blood pressure in a living body, comprising:a proximal tube (11) having a distal end and a proximal end;a distal tube (12) having a distal end and a proximal end, which is connected to the distal end of the proximal tube (11);a fluid-permeable coil (13) having a distal end and a proximal end, which is connected to the distal end of the distal tube (12);a distal tip (14), in which the distal end of the fluid-permeable coil (13) is secured; and a core wire (16), which is attached in the proximal tube (11) and which extends through a portion of the proximal tube (11), the distal tube (12) and the fluid-permeable coil (13), and is secured in the distal tip (14), wherein the distal end of the proximal tube (11) and the proximal end of the distal tube (12) are connected by a butt joint and wherein the core wire (16) is glued or brazed to the inner wall of the proximal tube (11) at or close to the butt joint.
