Description
所属技术领域Technical field
本发明专利涉及一种用于无创测量中心静脉压的测量尺。The patent of the present invention relates to a measuring ruler for non-invasive measurement of central venous pressure.
技术背景technical background
目前临床上中心静脉压的测量多用于检测危重患者循环血容量与心功能状态的改变或适用于辅助判断严重休克的病因，中心静脉压的动态变化可更好的体现补液过程中对液体复苏的反应性，有利于指导休克的治疗。目前中心静脉压的测定多采用锁骨下静脉或颈内静脉置管的方式达成。但这种发生可能发生以下并发症：肺及胸膜损伤、胸导管损伤、动脉及静脉损伤、导管栓子、空气栓塞、心率失常、心脏骤停、静脉血栓形成及导管相关感染等。此外，对于怀疑感染性休克的患者，需通过测量中心静脉压与心源性休克相鉴别并通过检测中心静脉压指导早期复苏，但对于普通病房的医护而言，中心静脉穿刺置管并非其常规诊疗手段，行中心静脉置管风险高、时间长，且中心静脉置管后尚需常规行X线检查以明确导管位置；这不仅提高了诊疗风险，还延误了病情，可能会使患者错失早期液体复苏的时机。At present, the measurement of central venous pressure is mostly used to detect the changes of circulating blood volume and cardiac function in critically ill patients or to assist in judging the cause of severe shock. The dynamic changes of central venous pressure can better reflect the fluid resuscitation process during fluid infusion. Responsiveness is helpful to guide the treatment of shock. At present, the measurement of central venous pressure is mostly achieved by catheterization in the subclavian vein or internal jugular vein. However, the following complications may occur in this case: lung and pleural injury, thoracic duct injury, arterial and venous injury, catheter embolism, air embolism, cardiac arrhythmia, cardiac arrest, venous thrombosis, and catheter-related infection. In addition, for patients with suspected septic shock, it is necessary to measure central venous pressure to differentiate from cardiogenic shock and guide early resuscitation by measuring central venous pressure. Diagnosis and treatment methods, the risk of central venous catheterization is high and the time is long, and routine X-ray examination is required after central venous catheterization to clarify the position of the catheter; this not only increases the risk of diagnosis and treatment, but also delays the disease, which may cause patients to miss early stages Timing of fluid resuscitation.
发明内容Contents of the invention
本发明专利提供一种用于无创测量中心静脉压的测量尺。该测量尺通过测量胸骨角水平到颈静脉搏动点的垂直距离估测中心静脉压，从而指导诊疗。既降低了诊疗风险，又可早期快速测量出中心静脉压以指导诊疗。The patent of the present invention provides a measuring ruler for non-invasive measurement of central venous pressure. The measuring ruler estimates the central venous pressure by measuring the vertical distance from the sternal angle level to the jugular venous pulse point, so as to guide diagnosis and treatment. It not only reduces the risk of diagnosis and treatment, but also can measure the central venous pressure early and quickly to guide diagnosis and treatment.
本发明专利解决其技术问题所采用的技术方案是：不论患者的体位是半卧位或坐位胸骨角皆均在右心房之上约5cm处。该无创中心静脉压测量尺由垂直标尺、水平杆、套管及重锤线组成，垂直标尺和水平杆穿过套管相互垂直，当重锤线与垂直标尺平行且水平杆一端紧贴颈静脉搏动点、垂直标尺零点端紧贴胸骨角，读出套管在垂直标尺上的刻度数值，即可推算出中心静脉压。The technical solution adopted by the patent of the present invention to solve its technical problems is: no matter the patient's position is a semi-recumbent position or a sitting position, the sternal angle is all about 5 cm above the right atrium. The non-invasive central venous pressure measurement ruler is composed of a vertical scale, a horizontal rod, a sleeve and a weight line. The vertical scale and the horizontal rod pass through the sleeve and are perpendicular to each other. When the weight line is parallel to the vertical scale and one end of the horizontal rod is close to the jugular vein The pulse point and the zero end of the vertical scale are close to the sternal angle, and the central venous pressure can be calculated by reading the scale value of the cannula on the vertical scale.
本发明专利的有益效果是：一、降低了中心静脉压检测的风险。二、简化了中心静脉压测量的步骤，可早期快速测量出中心静脉压以指导诊疗。The beneficial effects of the patent of the present invention are: 1. The risk of central venous pressure detection is reduced. 2. The steps of central venous pressure measurement are simplified, and the central venous pressure can be measured early and quickly to guide diagnosis and treatment.

How to use the non-invasive central venous pressure measurement ruler: 1. Raise the head of the bed so that the patient is in a semi-recumbent position; 2. The physician gently presses the external jugular vein above the clavicle with a finger, and releases the finger after the vein above the pressure point is filled; 3. Observe Jugular vein pulse point, place the zero end of the vertical scale on the sternal angle, adjust the vertical scale to make it parallel to the hammer line, adjust the cannula and the horizontal rod so that one end of the horizontal rod is close to the jugular vein pulse point; 4. Read The lower edge of the cannula corresponds to the scale H 1 cm on the vertical scale; 5. Calculate the central venous pressure (CVP), CVP=(H 1 +H 2 +5)cmH 2 O.
