Description

A kind of mini infusion pump

technical field

The utility model relates to the technical field of medical devices, in particular to a mini infusion pump.

Background technique

The infusion pump is usually a mechanical or electronic control device, which controls the infusion speed by acting on the infusion catheter. It is often used in situations that require strict control of infusion volume and drug dosage, such as in the application of vasopressor drugs, antiarrhythmic drugs, intravenous infusion or intravenous anesthesia for infants and young children. The following will talk about the problems that should be paid attention to in the daily operation, maintenance and storage of infusion pumps in combination with clinical practical applications.

Intravenous infusion is a common way of administration in clinical treatment. According to the nature of the drug and the constitution of the patient, the speed of intravenous infusion is also different. If the infusion is too fast or too slow, it is difficult to achieve the expected therapeutic effect, and even affect the safety of nursing. At present, the common infusion set widely used clinically mainly relies on the pressure of the liquid level difference to infuse liquid into the recipient, and relies on the nursing staff to observe with the naked eye and manually adjust the wheel clamp to control the infusion speed. Ordinary infusion sets lack functions such as blockage alarm, bubble alarm, and liquid infusion alarm, which increases the burden of clinical care; and the liquid bottle is easy to introduce external air-contaminated liquid. Infusion pump The infusion pump is an instrument that can accurately control the number of infusion drops or the flow rate of the infusion to ensure that the drug can enter the patient's body at a uniform speed, accurately and safely. It is also an intelligent infusion device. The speed is not affected by the back pressure of the human body and the operator, and the infusion is accurate and reliable, which helps to reduce the intensity of clinical nursing work and improve the accuracy, safety and quality of infusion.

The existing infusion pump has a large volume and is inconvenient to carry.

For this reason, a kind of mini infusion pump is proposed.
