有创动脉血压监测是将动脉导管置入动脉内直接测量动脉内血压的方法，适用于休克、重症疾病、严重的周围血管收缩、进行大手术或有生命危险手术病人的术中和术后监护、其他存在高危情况病人的监护。有创动脉血压监测具有以下优点：1）直接动脉压力监测为持续的动态变化过程，不受人工加压、袖带宽度及松紧度影响，准确可靠，随时取值；2）可根据动脉波形变化来判断分析心肌的收缩能力；3）应用血管活性药物时可及早发现动脉压的突然变化，4）集动脉血气标本减少患者痛苦。 Invasive arterial blood pressure monitoring is a method of directly measuring intra-arterial blood pressure by inserting an arterial catheter into the artery. It is suitable for intraoperative and postoperative monitoring of patients with shock, severe illness, severe peripheral vasoconstriction, major surgery or life-threatening surgery. , Monitoring of other high-risk patients. Invasive arterial blood pressure monitoring has the following advantages: 1) Direct arterial pressure monitoring is a continuous dynamic change process, not affected by artificial pressure, cuff width and tightness, accurate and reliable, and can be taken at any time; 2) It can be changed according to arterial waveform 3) The sudden change of arterial pressure can be detected early when vasoactive drugs are applied, 4) The collection of arterial blood gas samples can reduce the pain of patients.
目前有创动脉监测时的采血装置，它包括动脉导管、充满液体带有开关的压力连接管、压力传感器、连续冲洗系统和电子监护仪，如图1所示，操作前，先用碘伏对三通旋塞阀D进行消毒；动脉采血时，首先采用第一采血针A穿刺于与压力连接管连接的三通旋塞阀D，抽取动脉连接管E中的冲洗液；再采用第二采血针B穿刺于与压力连接管连接的三通旋塞阀D，进行采血；最后通过第三采血针C抽取三通旋塞阀D中残留的血液。采用此方法，尽管采用第三采血针C对三通旋塞阀D进行了废血清理，但是三通旋塞阀D处仍然会有残留血渍，存在血液感染的危险，而且会造成血液的浪费；另外，其操作工序复杂，也增加了耗材。 The current blood collection device for invasive arterial monitoring includes an arterial catheter, a pressure connection tube filled with liquid and a switch, a pressure sensor, a continuous flushing system and an electronic monitor, as shown in Figure 1. The three-way stopcock D is disinfected; when taking arterial blood, first use the first blood collection needle A to puncture the three-way stopcock D connected to the pressure connection tube, and extract the flushing fluid in the arterial connection tube E; then use the second blood collection needle B Puncture the three-way stopcock D connected with the pressure connection tube for blood collection; finally draw the residual blood in the three-way stopcock D through the third blood collection needle C. With this method, although the third blood collection needle C is used to clean the waste blood of the three-way cock D, there will still be residual blood stains at the three-way cock D, which may cause blood infection and waste of blood; , its operation procedure is complicated, also increased consumables.
