Clinically using infusion pumps infuse
patients with controlled doses of liquids, drugs or nutrients.
The pressure required to properly control
fluid depends largely on whether it is inserted into veins, subcutaneously or
arterially. In order to ensure correct measurement, the company recommends the
use of high-precision, high-resolution sensors. Miscalculation can lead to
serious complications and even death, so it is one of the most critical stress
applications in the medical industry.
In order to ensure correct medication, the
company recommends the use of small high
precision pressure sensors,
which can monitor the infusion pressure, make
the infusion pump to control the injection speed more precise and stable, and
can monitor the infusion process, greatly reducing the amount of manual
The infusion pump system consists of a
computer system, a driving mechanism, a detection device, an alarm device and
an input and display device. The detection device consists of pressure and
infrared sensors. SM5G and SM4x21 series of small high precision pressure sensors
sense the pressure signal of the
infusion pump. After amplification, the pressure signal is sent to the computer
system for signal processing, and the control instructions are obtained. Then
the corresponding control operation is carried out to maintain the pressure
required for infusion.
In the infusion pump, the small high precision pressure sensors
monitor the liquid pressure in the infusion tube so as to control the flow rate
of the liquid. When the pipeline of the infusion pump is blocked, the sensor
can detect the sudden change of pressure and alarm. The small pressure sensors is a
high reliability, high sensitivity and miniaturization sensor. Its accuracy is
1%-FS. It can accurately detect the infusion pressure of infusion pump. It has
two measuring configurations of surface pressure and differential pressure. It
has obvious advantages.
