The medical pressure sensor is a special medical pressure sensor. It is a specialized medical sensor that can sense pressure and convert it into a usable output signal. (Because the commonly used pressure sensors are mainly manufactured by the piezoelectric effect, pressure sensors can also be called piezoelectric sensors.)
Medical pressure sensor uses medical grade polycarbonate and polyvinyl chloride as the material of the sensor body and pressure measuring connection tube. The general packaging specifications are CH-DPT-248, CH-DPT-248Ⅱ, CH-DPT-248Ⅲ.
Medical pressure sensor type
Commonly used medical pressure sensors include medical negative pressure vacuum system pressure sensors, vacuum compression bag sensors, medical air pressure sensors, non-invasive medical sensors, blood pressure sensor boards, arterial pressure monitoring sensors, arterial pressure sensors, invasive medical sensors, ion beam sputtering Membrane pressure sensors, disposable medical pressure sensors, biomedical pressure sensors, sphygmomanometer pressure sensors, pressure sensors for medical infusion pumps, pulse direction sensors/pulse sensors, blood pressure sensors, tire pressure sensors, etc.
Medical pressure sensor function
Medical pressure sensors must be highly accurate and compactly packaged to facilitate carrying, especially when the device is to be directly connected to the patient. If the sensor is used in a monitoring instrument integrated with a medical device, standard packaging materials such as stainless steel and anodized aluminum should be used. If the pressure sensor device is in direct contact with the human body or liquid, special stainless steel or disposable sensors that can be autoclaved can be used.
Medical pressure sensors are usually used to monitor the human body's invasive blood pressure, such as arterial pressure, central venous pressure, pulmonary artery pressure, and left coronary artery pressure, to directly obtain the physiological parameter of blood pressure, which is useful for clinical diagnosis, treatment and diagnosis of diseases. Prognosis estimation provides objective evidence.
Medical pressure sensors were used for bed load monitoring in the early days, and now small pressure sensors are applied to areas that are prone to human error, such as infusion pumps for drug delivery. In order to adjust the flow rate as accurately as possible and facilitate monitoring by nurses at any time, people apply pressure sensors to infusion pumps. This kind of sensor can accurately measure the weight of the infusion bag. When the weight of the liquid is different from the preset value, the sensor will immediately send a warning message to the connected device and communicate with the controller in time.
With the advancement of science and technology and the development of society, the application of medical pressure sensors has been greatly popularized, and the sensitivity and stability have been greatly improved, which allows doctors to better judge the patient's condition. And many people with hypertension have their own sensors in their homes to monitor the patient's blood pressure at any time.
