In the minimally invasive world, it is inseparable from the leadership of medical MEMS sensors, which are like an extension of the human senses, converting the physiological signals of the human body into medical electrical signals, and is an important bridge between medical instruments and the human body.
The ZXPA invasive pressure sensor for minimally invasive medical field independently developed and produced by Smart Sensor is one of the smallest pressure sensors in the world, which can realize data capture and conversion of high stability, high accuracy and high-speed response of signals in vivo in harsh environments, adding more advanced and flexible solutions to the application of minimally invasive medical devices.
Miniature pressure sensors are very small in size
The ZXPA Invasive Pressure Sensor, designed for medical-grade invasive pressure measurement scenarios, is a product that can perform fixed-point pressure measurement in the human body.
Considering the biocompatibility, safety, and stability of this product, it is encapsulated without the need for gels or sealants. In addition, its size is only 650×220×75μm, in order to facilitate the application of medical device products, Smart Sensor breaks through the precision welding technology, and can be customized according to customer requirements for electric wire welding and leading, customized three rows of wires of different lengths, which can be pre-connected in different diameters of guidewire catheters, so as to help a variety of medical devices accurately monitor pressure changes in a small space.
Not only that, Smart Sensor can also provide signal calibration compensation circuit hardware, which can be used to analog amplified signal output or digital I²C signal output according to customer needs.
Product Advantages:
Size: 650×220×75μm
Pressure: -300~300mmHg (relative pressure 760mmHg)
Range: 460~1060mmHg absolute pressure (customizable)
Accuracy: ±1%FS
Recommended working temperature: 15°C~45°C
Material: Biocompatible material
Adapt to different environments in the body and improve the diagnosis and treatment effect of equipment
This miniature pressure sensor can be applied to different systems of the human body, such as cardiovascular system, digestive system, renal system, reproductive system, etc., and can be combined with a variety of medical equipment in different minimally invasive surgical scenarios such as cardiovascular FFR surgery, intracranial pressure, glaucoma, endoscopy, etc., to increase the function of pressure monitoring.
Typical technical applications
01 Cardiovascular FFR surgery
Placed in a 1-French medical catheter, it is able to move continuously with the bending of the blood vessel, and the level of blockage of the vessel is determined by measuring the pressure change
02 Intracranial pressure
Drainage of bloody or infected cerebrospinal fluid extracranial is also used to monitor, control intracranial pressure, and inject drugs into the central nervous system
03 Kidney surgery
Prostatic artery embolization (PAE) in BPH, a precise pressure sensing that prevents embolic agents from entering the bladder and rectum as they move through the renal arteries
04 Endoscope
Look at areas of blockage inside the body, such as kidney stones, and monitor the pressure in the kidneys during ureteroscopy
05 Ablation surgery
The higher the amount of refrigerant injected, the higher the pressure generated and the lower the temperature
……
Break the foreign monopoly and achieve domestic leadership
With the continuous advancement of the process of localization and substitution of MEMS technology, the successful practice of ZXPA invasive pressure sensor not only breaks the monopoly of foreign technology, but also reflects the domestic leading position of Smart Sensor in the field of intelligent MEMS pressure sensor with independent research and development and controllable production strength, and further expands the influence of domestic MEMS pressure sensor brand in the medical ecological chain.
It is worth mentioning that the wide penetration of minimally invasive surgery in the domestic market, as well as the gradual improvement of the coverage of disposable pressure sensors in the field of medical devices, will also usher in greater growth space for the supporting MEMS pressure sensors and minimally invasive medical device markets.
