The Heart of Medical Equipment—Respirator

  On average, an adult respires about 20,000 times a day. However, about 10% of those who are aged over 40 years old suffered from sleep apnea syndrome across the country. In order to alleviate and treat the health problem of respiration-related diseases, choosing an effective medical equipment, such as a respirator to help the whole treatment, matters. In the field of critical care medicine, respirator serves as a paramount equipment to support a life.

Why Is A Respirator Matters So Much

  As an effective equipment able to replace human’s autonomous ventilation function, ventilator has been widely used in emergency medical treatment including respiratory failures caused by various reasons, anesthesia and respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. (from Baidu Encyclopedia)

  In hospitals, respirators and ECMO are indispensable medical tools in the treatment of those who suffers from severe covid-19. While in some families, portable respirator plays as a “magic machine” to treat the sleep disordered breathing.  

Fan Selection for Respirators

  Fan, as the source of supply therapeutic gas, plays the core role of respirators. Those compact centrifugal fans used for respirators supplied by Hengrui, have obvious advantages in noises, response speed, dynamic pressure, temperature rise, volume and service life. Our products comply with FDA standard and relevant global regulations, and are widely used in ventilator equipment of famous brands at home and abroad.

  Ebmpapst compact RV45 series fans supplied by Hengrui are designed for continuous positive airway pressure ventilation (CPAP) and pressure adaptive operation (APAP / Auto APA and bilevel / BiPAP). The design of motor, control electronics and aerodynamics must ensure that all components support and cooperate with each other in order to meet different requirements.

The Application Advantages of Ebmpapst Fans in Respirators:

Compact structure, the volume is only 64x69.5x54.5mm, and the weight is only 135g

Able to work under the DC voltage of 12V and 24V

Consume about 43W under free work condition

The maximum natural air flow is up to 410 L / min and the maximum pressure rise exceeds 5000 PA

All parts in contact with air are made of materials conforming to FDA standards, which are harmless to human body

Low working noise

  The conveying velocity (linear) and conveying pressure (square) of the centrifugal fan impeller increase with the rotating speed. The rotating speed up to 50000 RPM can make the structure of the fan very compact. Rv45 series fans do not contain motor drive and control electronic components, which must be connected externally, so that the fan can be used in specific applications. According to the specific medical equipment, users can self optimize the control system. However, for standard products or rapid test applications, the control module provided by the manufacturer can be used. "Power module RV45" is suitable for simple speed control and includes speed counting output, so as to provide customers with plug and play solution.

The maximum natural air flow is up to 410 L/ min and the maximum pressure rise exceeds 5000 PA.

  Apart from respirator-related medical equipment, Ebmpapst fans provided by Hengrui can also applied to dynamic ventilation of fuel cells, air filtration technology, packaging machines, smoke detection systems, printed circuit board production or exhaust systems for welding and welding gases.
