Description
Technical Field
The utility model belongs to the technical field of medical appliances, and particularly relates to an arterial blood pressure and blood gas monitoring device.
Background
In addition to the routine monitoring of vital signs including body temperature, blood pressure, respiration, electrocardiogram, urine volume, etc. for critically ill patients, general anesthesia patients, especially ICU patients, other monitoring measures such as electroencephalogram monitoring for craniocerebral patients, central venous pressure monitoring for hypotensive or shock patients, blood gas monitoring for patients with mechanical ventilation or possibly impaired respiratory function, and other indicators such as blood ph, blood routine indicators (red blood cells, white blood cells, platelets, hemoglobin, electrolyte concentration, etc.), heart, liver and kidney functions must also be monitored regularly.
Some indices such as body temperature, respiration, electrocardiogram, urine volume can be continuously monitored by a noninvasive method, and some indices can be continuously monitored by an invasive method such as arterial blood pressure and central venous pressure. Some patients need to take blood samples frequently for monitoring, such as arterial blood for blood gas analysis or venous blood for observing liver and kidney functions, blood insulin, ketone bodies, lactic acid, conventional blood indexes, electrolytes and the like every 2 hours and 1 hour. This frequent blood sample collection method considerably increases the difficulty of the work, especially when arterial blood is taken for blood gas analysis, not only is puncture difficult and complications easily occur, but also the result is different or the accuracy of the result is affected.
Clinically, the invasive arterial blood pressure monitoring is generally performed by a normal operation of a severe patient, such as arterial puncture can be performed by using an arterial indwelling needle, a disposable blood pressure sensor is externally connected, the latter transmits the pressure signal in the blood to the blood pressure sensor chip through the liquid, and then converts the pressure signal into a digital signal and reflects the digital signal on the monitor through the data line. In order to avoid the invariable repeated arterial blood sampling during blood gas analysis, the existing products on the market are additionally provided with blood sampling modules (mainly a syringe surrounded by silica gel and blood sampling points) on the basis of the existing blood pressure sensor, so that repeated arterial puncture of patients is avoided, but the method has the defects that, each time the needle is still required to be used for puncturing a blood sampling point and a few milliliters of blood is wasted, the syringe surrounded by the silica gel has a small amount of residual blood after each operation, and the syringe is difficult to flush, so that adverse effects such as increasing the probability of infection can be caused. The blood that is pierced is inevitably exposed to air through a needle tip or the like due to a complicated operation until entering the blood gas analyzer, and the accuracy of the result is affected even though the exposure of the process is small and short.
