Installation and usage methods of medical pressure sensors

With the rapid development of technology in medical institutions, there are more and more types of medical pressure sensors, and different types of pressure sensors have different functions. In recent years, medical pressure sensors have been widely developed in many fields, especially in detection. Below, the editor of Aichi Mall will provide a detailed introduction to the installation and usage methods of medical pressure sensors.

medicalScope of application of pressure sensors

Used for monitoring invasive blood pressure such as arterial pressure, central venous pressure, pulmonary artery pressure, and left coronary artery pressure in the human body, directly obtaining the physiological parameter of blood pressure, providing objective basis for clinical diagnosis, treatment, and prognosis estimation of diseases.

Structural specifications of medical pressure sensors

Select medical grade polycarbonate and polyvinyl chloride as the materials for the sensor body and pressure measuring connection pipe. The packaging specifications are ch-dpt-248, ch-dpt-248 ii, and ch-dpt-248 iii. Installation Procedure for Medical Pressure Sensors

(1) Turn on the monitor before connecting the pressure sensor system.

(2) Use disinfection measures to open the packaging and confirm that all interface safety seals and auxiliary components such as three-way valves are in good working condition.
Attention: When connecting the connector, do not tighten it too tightly.

(3) All ports of the plug valve should be covered with protective caps with holes until the sensor system is filled with heparin saline solution and all bubbles are discharged before replacing them with protective caps without holes.

(4) Connect the pressure sensor to the monitor and zero it according to the monitor instructions.

Attention: (a) If zero adjustment is not possible, please replace the sensor and reset it; If the zero adjustment is not successful, please check whether the cable connection, monitor, etc. are normal; (b) When installing dpt-248 ii and ch - dpt-248 iii sensors, color coding should be used to distinguish the type of blood pressure: red - arterial pressure; Blue - central venous pressure; Yellow - Pulmonary artery pressure; Green - Left coronary artery pressure; White - Other.

(5) Flush the pipeline with heparin physiological saline and exhaust the air in the pipeline. Attention: There should be no residual bubbles in the pipeline.

(6) After filling all pipelines with heparin saline, connect the sensor system to the human body.
