In the medical market in Europe and the United States, the performance requirements for medical electric syringes are extremely strict. With the continuous development of medical technology, there are more and more personalized treatment options for various diseases, which requires medical electric syringes to be able to accurately adapt to different drug characteristics and patient needs. Healthcare manufacturers in Europe and the United States face significant challenges in improving product accuracy, safety, and patient experience. In this context,BG Motor has launched an in-depth cooperation with a well-known European and American medical manufacturer to equip its new medical electric syringe with a high-performance drive motor.
1.High-precision injection requirements: The treatment doses of different drugs vary slightly, and the accuracy of the injection location has a significant impact on the treatment effect. For example, dose deviations can cause a large fluctuation in the patient's blood sugar when insulin injection is used to treat diabetes. Traditional motors have difficulty meeting such high-precision injection requirements and cannot ensure that each injection can accurately deliver the drug to a predetermined location.
2.Safety and sealing: If the medical electric syringe is in direct contact with the drug, any leakage may lead to drug contamination, affect the treatment effect and even endanger the health of the patient. At the same time, syringes need to be used frequently, and the motor must always maintain good sealing during long-term operation to prevent external impurities from entering, which puts high requirements on the structural design and material selection of the motor.
3.Low noise operation: In a medical environment, noise will bring additional psychological pressure to patients, especially in some noise-sensitive treatment scenarios, such as pediatrics, geriatric wards, etc. The noise generated during operation of traditional motors is difficult to meet the needs of a quiet medical environment.
4.Material biocompatibility: Since some components of the motor may indirectly contact the human body, the materials used must be ensured that they do not cause allergies or other adverse reactions. This requires strict screening and testing of motor production materials to comply with strict European and American medical device biocompatibility standards.
High-precision control: DC brushless motors are equipped with advanced closed-loop control system. The motor uses high-precision position sensor with accuracy up to ±0.1°, which can accurately monitor the motor rotor position in real time. Combined with the precise control algorithm, the motor speed control accuracy can reach ±0.5% and the torque control accuracy can reach ±1%. This enables medical electric syringes to push drugs with extremely high accuracy, ensuring that the error of each injection dose is controlled within a very small range, meeting the strict requirements for drug doses of different patients. For example, when injecting anti-cancer drugs, the dosage per microgram level can be accurately controlled, while accurately positioning the injection location to improve the therapeutic effect.
Optimize structural design to ensure sealing: The motor adopts an integrated sealing structure design, and special customized sealing materials are used in key parts. These materials not only have excellent sealing performance, but also can withstand chemical corrosion of drugs. The motor shell is precision-processed and closely cooperates with the syringe body to form a double seal protection, effectively eliminating the risk of drug leakage and ensuring the purity of the drug and the treatment safety. The motor has an protection level of IP67, which can effectively protect against dust and water, ensuring that good sealing can be maintained in complex use environments.
Low noise design:Optimize the internal structure of the motor.Optimize the design of the stator and rotor of the motor, and adopts a special high-magnetic and low-loss silicon steel sheet material, with iron loss below 1.0W/kg (1T, 50Hz). It is paired with a unique winding process to greatly reduce the electromagnetic noise during the motor operation. At the same time, high-precision and low-friction components are used in key parts such as motor bearings, and special lubricating materials are added to reduce the noise generated by mechanical friction. After testing, the noise value of this DC brushless motor is below 40dB (A) when running at full load, which is significantly lower than that of traditional motors, providing patients with a quiet and comfortable treatment environment.
Select biocompatible materials: During the motor manufacturing process, all materials that may indirectly contact the human body are strictly screened. For example, the insulating material inside the motor uses a special polymer that meets European and American biocompatibility standards. This material not only has good electrical insulation properties, but also has an insulation resistance of more than 1000MΩ, but also undergoes strict biosafety testing to ensure that no harmful substances are released and that they will not cause allergies or other adverse reactions in the patient.
Customized services and technical support:Preliminary communication and customized design: In the early stages of the project launch, BG's professional technical team communicated in depth with European and American medical manufacturers to learn more about its performance requirements for medical electric syringes. According to customer feedback, the DC brushless motor solution is customized for it. From the motor's appearance size, installation method to electrical performance parameters, the characteristics and use scenarios of the customer's products are fully considered to ensure that the motor and the syringe are perfectly matched. This customized motor has a rated voltage of 24V DC, a rated speed of 3000rpm, and can output a rated torque of 0.5N・m, which can stably adapt to the working needs of the syringe.
1.Provide regular maintenance services: Provide regular motor maintenance services to customers, and formulate personalized maintenance plans based on the motor usage frequency and working environment. The after-sales team regularly comes to the door to inspect, clean, maintain the motor, etc., to promptly discover and solve potential problems, ensure that the motor is always in the best operating state, and extend the service life of the motor.
2.Technical training and upgrade services: Provide professional motor technical training to customers' technicians regularly, including motor principles, operating methods, fault diagnosis and troubleshooting, etc., to help customers improve their technical level and maintenance capabilities. At the same time, with the continuous development and update of technology, we will provide customers with timely upgraded motor software and hardware services, so that customers' products will always maintain a leading technological advantage.
3.Customer feedback and continuous improvement: attach great importance to customer feedback and establish a complete customer feedback mechanism. Through regular follow-up visits to customers and collecting customer opinions and suggestions, we will continuously optimize product performance and after-sales service quality. Use customer feedback as an important basis for product research and development and improvement, continuously improve product competitiveness, and provide customers with better products and services.
