Infusion Pump

An infusion pump is a medical device used in conjunction with a syringe to precisely control the quantitative injection of small doses of drugs or liquids into a patient's body. It is widely used in various clinical departments, and its functions and characteristics are as follows:

Characteristic

High precision:

It can accurately control the dosage and flow rate of drugs, with high control accuracy. When ≥ 30% full stroke, the control error of some injection pumps is ≤± 0.5%, ensuring that the absorption and action of drugs are consistent with expectations, and ensuring the therapeutic effect.

Multi channel and multi specification adaptation:

 There are various types such as single channel, dual channel, and multi-channel (four channel, six channel, etc.), which can simultaneously or separately control the delivery of multiple different drugs; It can adapt to various specifications of syringes and automatically recognize syringes to meet the needs of different treatment plans and drugs.

Intelligence and automation: 

integrating advanced electronic technology and microcomputer control technology, preset infusion parameters, and automatically perform drug infusion according to the settings; Some can also monitor the patient's physiological indicators and infusion status in real-time, such as pressure, temperature, etc. Once abnormalities occur, an alarm will be immediately issued and infusion can be automatically stopped; Some also support drug inventory management, real-time monitoring of remaining medication levels and reminding medical staff to replenish.

Easy to operate:

The operation interface is usually simple and clear, and medical staff can easily set infusion parameters after simple training, achieving fast and accurate infusion operations; Some infusion pumps are also equipped with optional foot operated switches, further facilitating use.

Portability:

Modern infusion pumps are increasingly emphasizing portability, with small size, light weight, and some being dual-use for both AC and DC. After the built-in battery is fully charged, the pump can run continuously for a long time (such as a single micro infusion pump with a built-in battery that can run continuously for more than 3.8 hours), making it convenient for patients to use in different medical places (such as wards, emergency rooms, and operating rooms) or at home, improving the flexibility of treatment and enhancing the quality of life of patients.

Stable operation:

The entire infusion process runs at a constant speed without pulses, and the working state is stable, ensuring that the drug can enter the patient's body continuously and stably; When transporting liquids of various properties, it is usually only necessary to replace the syringe, without the need for complex cleaning operations

Usage:

Precise administration:

It can deliver drugs such as chemotherapy drugs, cardiovascular drugs, insulin, various hormones, etc. at a precise speed and dose according to the doctor's instructions, eliminating dosage errors caused by human factors during manual injection, improving the accuracy and safety of medication, and ensuring treatment effectiveness. For example, in tumor chemotherapy, accurate drug dosage is crucial for treatment effectiveness and reducing side effects.

Meeting diverse treatment needs:

With multiple administration modes, common ones include continuous injection (suitable for situations that require continuous administration, such as intravenous nutrition support, continuous infusion of analgesics, etc.), intermittent injection (suitable for treatments that are administered at certain time intervals, such as antibiotic therapy), and pulse injection (can meet the needs of specific administration modes, such as certain drug treatments for heart disease patients), which can better adapt to the needs of different diseases and treatment scenarios.

Ensure treatment safety:

It has multiple alarm functions, such as injection completion alarm, injection speed abnormal alarm, injection pipeline blockage alarm, residual prompt, limit to volume alarm, etc. These alarm functions can promptly remind medical staff to pay attention to the injection status, prevent unexpected situations, and reduce medical risks.

Improving medical efficiency:

Some infusion pumps are equipped with voltage and current signal outputs, which can be connected to printers and computers, making it convenient for medical staff to record and trace key parameters during the injection process, such as infusion speed, dose, time, etc., providing data support for treatment evaluation and research; It can also be connected to a time controller to achieve automated infusion control and reduce the workload of medical staff.

Improving patient comfort:

For patients who require long-term infusion or continuous medication, the pain of frequent manual injections is avoided; At the same time, slow injection of drugs can reduce the stimulation of the skin and tissues by the drugs, and alleviate the pain of patients during the injection process; Some infusion pumps have built-in heating function, which can improve the comfort of infusion and reduce the probability of drug leakage.
