Development and Application of Intelligent Infusion Pump Control Panel Lock

In the field of modern medical care, intelligent equipment is gradually popularized, and it plays a key role in improving the treatment effect and ensuring the safety of patients. One of the important intelligent devices is the "intelligent infusion pump". It not only can automatically adjust the infusion speed, but also has the functions of alarm and prompt, which effectively avoids the misoperation and infusion risk caused by human factors.

However, there are also many problems in the use process. For example, when medical staff make adjustments, if they accidentally touch other keys, the original settings may change; If children or patients with mental illness touch the control keys by themselves, it is more likely to cause accidents ... These have brought great challenges to clinical nursing. In view of the above hidden dangers, we designed a brand-new product-intelligent infusion pump control panel lock.

First, the design concept

This product is mainly based on two considerations:

1. Protection function: limit the operating authority of non-professionals to the instrument by physical means.

2. Convenience: Try to reduce the workload of nurses and other professionals under normal circumstances.

Second, the technical realization mode

The microcontroller is used as the core processing unit, and the hardware platform is composed of various sensors and motor drive circuits. The software part is composed of upper computer program (used for debugging and maintenance) and embedded system application program.

The specific process is as follows:

(1) when the keyboard area needs to be locked, the trigger signal is transmitted to the MCU； by pressing the special switch button;

(2) MCU judges whether to execute the next action according to the received information;

(3) If the conditions are met, start the stepping motor to rotate for a certain angle to move the baffle to cover all keys;

(4) Similarly, the unlocking process only needs reverse operation.

Third, the advantages and characteristics

1. Stable and reliable: the whole mechanism is simple and clear without too many complicated parts, which reduces the failure rate and is convenient for maintenance;

2. Easy installation and disassembly: it can be directly assembled on most types of infusion pumps in the market without additional structural modification of the machine itself;

3. Convenient and quick to use: the locking/unlocking task can be completed only by gently pressing once, which saves the tedious steps of repeatedly confirming the correctness of each step in the traditional method;

4. High efficiency and energy saving: All the power supplies used are of low power consumption type, and long-term operation will not produce excessive energy consumption.

Fourth, summary

With the development of science and technology, all kinds of innovative medical devices came into being, which greatly improved the work efficiency and reduced the probability of errors. As a practical and easy-to-popularize product, the intelligent infusion pump control panel lock will be more widely used in the future.
