Summary: With the development of technology, various types of smart medical devices are flooding into the market. These devices are usually in direct contact with the human body (patients or operators), so there are strict requirements for safety regulations, which are in the medical certification EN 60601-1, 3rd. There are clear requirements. Isolating the power supply in the whole system plays a key role in the safety requirements such as creepage distance and leakage current. Therefore, this requires that the power module needs to keep up with the requirements of smart medical treatment, further improve the isolation performance, and even meet 2 The isolation protection requirements of MOPP. 1 Overview: The main reasons for medical malpractice in the infusion method are as follows: 1. The nurse fails to pull the needle immediately after the infusion is completed, causing the patient to return blood; 2. During the infusion process, the infusion rate is too fast or the needle is blocked, and it is not found in time. 3, the patient's body may have abnormal reactions such as allergies, and has not been treated in time, and the new intelligent syringe pump can well avoid these problems. The syringe pump is usually a mechanical or electronic control device. It is used for controlling the infusion rate and dosage by acting on the infusion catheter. It is often used in situations where strict control of the infusion volume and dosage, such as injection of a booster drug, antiarrhythmic drug, Infant or child intravenous infusion or intravenous anesthesia. With the increasing use of syringe pumps, the safety requirements of their complete systems are becoming more stringent. The high isolation performance of the power module plays a vital role in the overall system security work, which can help the system avoid related security risks. It can be said that the rise of the syringe pump has spawned the birth of an isolated power supply with high isolation performance. 2, the injection pump structure block diagram: Figure 1 above is the most common single-channel syringe pump solution block diagram, which can be roughly divided into software systems, mechanical systems and electrical systems. The detailed division can be divided into: main control system, power supply system, motor drive system, pressure detection system, automatic alarm system. The most basic working principle is that the control component drives the operation of the mechanical component by controlling the stepping motor, and a special sensor module detects the actual situation in real time and feeds back to the control component. Simply put, the working principle of the electrical part of the syringe pump is shown in Figure 2: Tetanus Vaccine,Hepatitis B Vaccine For Adults,Tetanus Booster,Td Vaccine FOSHAN PHARMA CO., LTD. , https://www.fs-pharma.com
