摘要： A catheter having a proximal shaft and a distal shaft each having a proximal end section and a distal end section. The distal end of the proximal shaft and the proximal end of the distal shaft are connected to each other, a catheter holding hub is connected to the proximal end of the proximal shaft, and a part of at least the distal shaft is constructed from an inner shaft and an outer shaft coaxially surrounding the inner shaft. The inner shaft is extended out from the outer shaft to the distal side. The lumen of the inner shaft forms a guidewire lumen. The catheter has a means for restricting relative movement of the outer shaft and the inner shaft occurring when pressing force exceeding a predetermined level is applied to the catheter.

摘要： The present invention provides a catheter which makes it possible for a biaxial type balloon catheter having a flexible structure in the joint part between a sleeve on the proximal side of the balloon and a shaft on the distal side thereof, showing no abrupt change in rigidity, reducing the step, and capable of being smoothly advanced through highly constricted and curved blood vessel portions, to be manufactured easily with a high production yield using a small number of manufacturing steps. The balloon catheter is a biaxial type for medical use, wherein only the inflation lumen of the shaft is removed from the area extending from the joint part between the shaft and the balloon sleeve on the proximal side to the distal end of the shaft, and main walls of the inflation lumen on the distal side from the joint part are formed by the proximal side balloon sleeve.

摘要： A suction-type blood sampler has a housing (1), a lancet unit (2) having a rod (4) extending backward from the lancet unit, and a plunger (3) connected to the rod in the housing and having a seal (7) attached to a forward end of the plunger. The seal is in sliding airtight contact with an inner periphery of the housing. The lancet unit consists of a lancet body (11) having a forwardly extending needle (12) and held by a lancet retainer (18) which is in sliding contact with the inner periphery. The blood sampler further has first, second and third springs (8, 9, 10) placed between the lancet unit and the plunger. The second spring urges the lancet unit to project the needle forwards, and the third spring tends to retract it. The first spring acts to reduce air pressure in the housing when the plunger is released. The blood sampler also has an air sealing means (32) disposed in the plunger so as to exhaust air and inhibit ambient air from entering the housing, so that the skin is pierced sharply and quickly, and by introducing ambient air into the evacuated housing, just a required amount of blood can be taken accurately and without any fear that the blood will scatter when the open end of the housing is removed from the skin.
摘要翻译：抽吸式血液取样器具有壳体（1），具有从柳叶刀单元向后延伸的杆（4）的刺血针单元（2）和与壳体中的杆连接并具有密封件的柱塞（3） 7）连接到柱塞的前端。密封件与壳体的内周边滑动密封接触。刺血针单元由具有向前延伸的针（12）并由与内周滑动接触的刺血针保持器（18）保持的柳叶刀身（11）组成。血液取样器还具有放置在刺血针单元和柱塞之间的第一，第二和第三弹簧（8,9,10）。第二弹簧促使刺血针单元向前突出针，第三弹簧倾向于缩回。当柱塞被释放时，第一弹簧用于减小壳体中的空气压力。血液取样器还具有设置在柱塞中的空气密封装置（32），以便排出空气并且抑制环境空气进入壳体，使得皮肤被锐利地和快速地刺穿，并且通过将环境空气引入抽真空的壳体中，可以准确地取出所需量的血液，并且不用担心当外壳的开口端从皮肤上移开时，血液会散开。
