Abstract:
The invasive arterial blood pressure(ABP)monitoring technique is widely utilized in the management of critically ill patients,providing medical professionals with real-time,continuous,and dynamic blood pressure data that plays a crucial role in guiding patient treatment.However,current traditional methods for arterial catheter blood collection and zero setting and measurement technology for ABP and central venous pressure(CVP)present certain issues such as complex operation procedures,inaccurate zero setting,and the inability to simultaneously monitor both ABP and CVP.Additionally,these methods may increase the risk of bloodstream infection and occupational exposure.Therefore,the department of critical care medicine at Tianjin Medical University General Hospital has developed a vascular access convenient blood collection device which has been granted a National Utility Model Patent(patent number:ZL 202322581247.4).This device includes a connecting tube,a specimen collection structure,a blood suction structure,a multifunctional pressure measurement device with laser emission structure,a pressure measurement conversion structure,and an efficient vascular access blood collection device.By optimizing the blood collection procedure and simplifying the manometry process,this design reduces the risk of bloodstream infection for patients and minimizes occupational exposure for medical staff.The device ensures accurate zero point adjustment of pressure measurements while guaranteeing the authenticity and reliability of collected data.Additionally,it supports synchronous monitoring of ABP and CVP,thereby saving medical consumables and reducing workload for healthcare professionals.This simple yet safe and efficient device meets clinical requirements effectively and is highly recommended for widespread use.
