1、This paper mainly introduces the design of an intelligent temperature control system which realizes the function of temperature measurement and control by using single bus digital temperature sensor DS18B20 and single chip microcomputer. The core components of the system are AT89C51 microcontroller
2、and DS18B20 temperature sensor.下肢动脉硬化闭塞症腔内治疗入路选择新疆自治区人民医院血管外科穿刺的概念- Virtually every vascular procedure begins with a needle stick, using a thinwall puncture needle.事实上每一个血管介入手术都是始于针的穿刺- Seldinger Technique =1. Access the vessel with an entry needle用针穿刺血管2. Wire Guide (guide wire) brought in through
3、the needle.通过针导入导丝3. Needle is removed, leaving wire in place.保留导丝，移出针4. Over that wire, a catheter is advanced into the vessel. 通过导丝导入导管进入管腔穿刺器材 不锈钢金属套管针：由金属针芯和套针构成，针芯为尖头 无针芯穿刺针：常用 以 “ G”(Gauge) 表示穿刺针的管径，数字越大，管径越细，如 18G， 21GSeldinger技术操作过程穿刺 尖头刀片在穿刺点作一 3-5mm左右的小切口，用小弯血管钳稍作皮下分离后，左手轻压穿刺点，右手持针以与皮肤成 30
4、-50度角对准动脉进针进针方法有两种： 前后壁穿透法： 前壁穿刺法： 主张采用前壁穿刺法，以减少对血管壁的损伤 Seldinger Technique: Double WallSeldinger Technique: Single WallModified Seldinger TechniqueSingle (anterior) wall puncture注意事项在透视下进导丝，以防进入旋髂外动脉、在透视下进导丝，以防进入旋髂外动脉、股深动脉股深动脉 ；如发生， 可小心将导丝退至股动可小心将导丝退至股动脉或穿刺针内，旋转导丝或水平改变穿刺针脉或穿刺针内，旋转导丝或水平改变穿刺针角度后再进导丝。
5、角度后再进导丝。穿刺部位的选择动脉穿刺 股动脉 腘动脉 膝下动脉 肱动脉 腋动脉静脉穿刺 股静脉 颈内静脉 门静脉 肝静脉Garcia et al, Catheter Cardiovasc Interv 2009;74:27-36COMMON ACCESS SITES FOR PERIPHERAL=FOR CORONARYGarcia et al, Catheter Cardiovasc Interv 2009;74:27-36LESS COMMON ACCESS SITES FOR PERIPHERALFOR CORONARYThis paper mainly introduces the
