Possibilities of Coreless Motors in Electric Blood Collection Systems

With the rapid development of medical technology, electric blood collection systems have become an efficient part of modern medical equipment. This system is widely used in medical diagnosis, laboratory examinations and disease collection, especially in the process of rapid and accurate blood sample collection. The traditional blood collection method relies on manual operation and has fire defects, such as low efficiency, poor accuracy, and high technical requirements for operators. The electric blood collection system solves these problems in an automated and precise way, which not only greatly improves the operating efficiency, but also ensures the safety and accuracy of the blood sample collection process.

 

 

The electric blood collection system uses precision control to automatically collect blood samples, improving the process and accuracy of traditional manual blood collection. The work of the entire system usually includes three core steps:

 

Automatic drive of the gong needle: The first step of the electric blood collection system is the precise positioning and suffocation of the gong needle. This part uses a micro-servo or stepper motor to drive the advancement and recovery of the gong needle. The role of the motor is to ensure that the gong process is smooth and accurate, and to avoid affecting the blood collection effect due to excessive or insufficient force. The recovery and stability of the micro-servo widely achieve this purpose.

 

Negative pressure suction system: The next step is to draw blood into the collection tube through negative pressure suction. This process relies on a motor-driven pump system to generate negative pressure. Common motors include stepper motors and micro DC motors. Stepper motors can accurately control the start and stop of the pump, while micro DC motors can provide continuous suction to ensure the stability of blood flow.

 

Pressure and blood collection speed adjustment: In order to avoid excessive suction causing instability to the patient, the electric blood collection system usually adjusts the suction force through the motor. This function also usually relies on the stepper motor, which can accurately control the output of the negative pressure pump to ensure the safety and comfort of the entire blood collection process.

 

Through the coordinated work of these motors, the electric blood collection system can not only automate the blood collection process, but also improve patient comfort while ensuring operational accuracy.

 

 

From the above we can see that the traditional electric blood collection system does not use Coreless motors, although it has unique advantages in many precision equipment. The main reasons are:

 

1. Mismatched requirements: The main advantages of coreless motors are high torque, low inertia, low noise and structural design, which are usually suitable for high-precision and high-response speed applications. However, the electric blood collection system is more concerned with stable negative traction pressure and pressure regulation, which do not require the exquisite fast response and high torque of coreless motors.

 

2. Low torque requirement: Coreless motors have good high torque and low inertia characteristics, but in electric blood collection systems, the torque required by negative pressure pumps and stepper needle drive systems is moderate, and traditional motor types such as micro guide motors or stepper motors can better meet these requirements.

 

3. Cost and technical limitations: The current cost of Coreless motors is still relatively high, and technically, the application of traditional motors in electric blood collection systems is relatively mature, with stable performance and easy control.

 

 

Although coreless motors are currently less used in traditional electric blood collection systems, with the growing demand for portable medical devices, the potential of this type of motor in electric blood collection systems cannot be ignored. As blood analyzers are gradually becoming smaller and more customized in modern medicine, portable electric blood collection systems also need compact and efficient motor technology to adapt to future market needs. In this context, Coreless motors have great potential for application in compact devices due to their design in compact devices.

 

Unlike traditional large-scale electric blood collection systems, portable electric blood collection systems emphasize small size, light weight, and stable performance, which are the advantages of Coreless motors. The design of Coreless motors provides high power density while taking up less space, making them very suitable for integration into miniaturized electric blood collection systems. With the continuous advancement of technology, in the future, Coreless motors will surely provide portable electric blood collection systems with higher flexibility, precise control, and flood motors, promoting the intelligence and application of this equipment in medical industry equipment.
