With the development of the medical device market, higher requirements are being placed on the use of pressure sensors in the medical industry, such as improvements in accuracy, reliability, stability, and size. Pressure sensors have good applications in minimally invasive catheter ablation and body temperature measurement.
Minimally invasive surgery not only reduces trauma to the surgical site but also significantly alleviates patient pain and facilitates a rapid recovery. Achieving this requires not only the surgeon's experience but also a variety of medical monitoring devices. Many medical devices used in this procedure are now miniature, such as various catheters and ablation devices. Catheters include thermodilution catheters, urethral tubes, esophageal catheters, central venous catheters, and intracranial pressure vessels. Besides their electrical conductivity, these catheters utilize temperature or pressure sensors, providing crucial support for successful patient pathology examinations and minimally invasive surgery. Temperature and pressure parameters are key to successful operation. The ability to place sensors close to the patient is critical for many applications, such as dialysis, where accurate measurement of dialysate and venous pressure is essential. Pressure sensors must be able to precisely monitor the pressure of dialysate and blood to ensure they remain within the set range.
Applications of this type require sensors that are small in size and resistant to liquid media. In many cases, sensors incompatible with liquid media require additional mounting components for protection, increasing the product's size, cost, and complexity. Liquid media resistance is particularly important when monitoring patient respiration, as the sensor must be able to withstand the patient's cough and exhaled humid air.
Medical pressure sensors are commonly used to monitor various invasive blood pressure parameters, such as arterial pressure, central venous pressure, pulmonary artery pressure, and left coronary artery pressure. They directly obtain this physiological parameter, providing objective evidence for clinical diagnosis, treatment, and prognosis. Early applications of medical pressure sensors included bedside weight monitoring; now, small pressure sensors are being used in areas prone to human error, such as infusion pumps for drug administration. To precisely regulate flow rate and facilitate continuous monitoring by nurses, pressure sensors are applied to infusion pumps. These sensors accurately measure the weight of the infusion bag, and when the fluid weight deviates from a preset value, the sensor immediately sends a warning to the connected device and communicates with the controller.
With the application of new technologies and materials, the performance and stability of pressure sensors have been significantly improved, further enhancing their application in the medical industry. Currently, countries worldwide are investing substantial human and financial resources in the development and application of medical pressure sensors.
Pressure sensors have been used in the medical industry for a long time. Since their inception, pressure sensors have been considered for applications in the medical field. In recent years, with further improvements in the performance of pressure sensors, their application in the medical industry has seen significant growth.
Pressure sensors are used in minimally invasive catheter procedures in the medical industry, and their placement is crucial. For example, during dialysis, they can accurately monitor dialysate and blood pressure, maintaining them within preset ranges. Sensors used in medicine not only need to be compact but must also withstand liquid media. Sensors that cannot withstand these conditions require additional protective components.
Pressure sensors in the medical industry require high precision and stability, making them a high-value category with an average selling price significantly higher than in other industries. Disposable cardiac catheters are the most consumed application of medical pressure sensors, used to monitor blood pressure in millions of surgeries annually; another major application is respiratory monitoring. ICBUY distributes a variety of pressure sensors, applicable not only to the medical field but also to industrial and civilian sectors.
With advancements in medical technology and societal development, the application of medical pressure sensors has become increasingly widespread, and their sensitivity and stability have been greatly improved, enabling doctors to better assess patients' conditions. Furthermore, many people with hypertension have these sensors at home to monitor their blood pressure at any time.
