Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fixing devices, in particular to an arm-type invasive monitoring sensor fixing device. Background Art
[0002] Invasive arterial pressure monitoring is one of the commonly used hemodynamic monitoring methods in ICU or during surgery. The most common method is radial artery puncture and catheterization. After the arterial sensor is connected to the monitor, the pressure signal is converted into an electrical signal, presenting a specific blood pressure value and waveform. At the same time, when performing invasive arterial pressure monitoring, the arterial sensor should be placed at the intersection of the ipsilateral mid-axillary line and the fourth intercostal space as the reference zero point for measurement. This is one of the important factors affecting the accuracy of invasive arterial blood pressure monitoring. Therefore, properly fixing the arterial sensor helps to accurately measure blood pressure, which is of positive significance for maintaining stable blood pressure in patients during surgery and reducing intraoperative and postoperative complications. The existing arterial sensor position fixation has the following technical problems:
[0003] 1. The position of the mid-axillary line is not easy to fix and is easy to fall off. It is easy to be contaminated when placed on the bed, increasing the risk of blood infection.
[0004] 2. When changing body positions, the sensor is easily pressed against the side or under the body, causing discomfort to the patient and increasing the risk of pressure sores. After each adjustment, the sensor must be recalibrated, which increases the workload of nurses, poor compliance with zero calibration, and reduces the accuracy of data. Frequent contact by operators increases the chances of catheter-related infection and cross-infection.
[0005] 3. Patients who generally use invasive arterial blood pressure monitoring use relatively more equipment during surgery. Frequent zeroing is inconvenient to operate and increases the psychological burden on patients. Frequent zeroing also increases the risk of catheter traction. Invasive devices are high-risk catheters. Once they are dislocated or disconnected, they can easily cause serious harm to patients.
[0006] Therefore, it is necessary to provide an arm-type invasive monitoring sensor fixing device to solve the above technical problems. Utility Model Content
