Examples of Motor Application to Medical Equipment
Here are some examples of how motors are used in medical equipment.
Note that there are various types of small motors.
Please refer to the following article for more information on the types of small motors and their applications other than medical equipment.
Introduction of Applications and Main Types of Small Motors
Surgical instruments
Pulse lavage, staplers, power tools, atherectomy catheters, and other surgical instruments use motors in their rotating and driving parts.
Surgery is a very delicate operation and requires motors that can be controlled with high precision.
In addition, since surgical instruments are sterilized at high temperatures and pressures by autoclave, durability under autoclave environment is also required for surgical instruments.
Brushless DC motors are recommended if you are looking for a motor for surgical instruments because of their high precision and durability.
Respiratory organs
Motors are also active in ventilators, CPAP, nebulizers, and other respiratory devices.
In medical ventilators, motors are used in components called "blowers" that regulate the timing and volume of inhalation. In order to provide adequate assistance with minimal patient strain, a blower that can deliver a large volume of oxygen and has an excellent ramp-up speed is required.
At the same time, there is a need for ventilators to be compact in terms of installation space savings and ease of operation. Brushless DC motors are also suitable for use in the blower of ventilators because of their compact size and high output.
Medical pump
Motors are also used in devices such as infusion pumps, dialysis machine pumps, and medical pumps such as electric injectors.
Because medical infusion pumps must accurately administer medication at a constant speed, a motor that can accurately control the rotational speed is essential.
In addition, pumps are used in dialysis machines, which are indispensable for kidney failure patients, in various processes such as dialysis, cleaning and disinfection of piping, and so on. Since each process requires a different motor speed, motors that can control the speed are required.
Inspection and Diagnostic Equipment
Inspection and diagnostic equipment such as MRIs, CTs, X-ray machines, biometric monitors, and electronic blood pressure monitors require motors to move pumps, fans, and drive units.
Air pumps are used in electronic blood pressure monitors, and motors are used to power the discharge.
Handpieces for dental treatment
Motors are also used in dental handpieces such as root canal treatment devices, implant treatment devices, and CADCAM.
In dental treatment, there are several factors that make patients feel uneasy, such as vibrations that resonate through the jawbone and the noise of rotating drills. In order to reduce patient anxiety and ensure safe treatment, motors for dental treatment equipment are designed to be quiet and to reduce vibration.
Recommended motors for medical equipment
Here, we introduce motors recommended for medical equipment from among Mabuchi Motor's products: in 2021, Electromag (now Mabuchi Electromag), a brushless motor manufacturer specializing in medical equipment applications such as ventilators and dental treatment handpieces, and in 2023, Oken Seiko (now Mabuchi Oaken), a company with high technological capabilities in small pumps, joined the group, enabling us to offer optimal proposals from a wide range of product lineups.
