Description

A kind of constant temperature infusion pump

technical field

The utility model belongs to the field of infusion pumps, in particular to a constant temperature infusion pump.

Background technique

Patent application number 201210368782.5 discloses a constant temperature infusion pump. The infusion pump uses an air pump to pressurize the infusion bottle to make up for the gravity pressure difference lost due to the lowered height of the infusion bottle. This pressure difference is accurately calculated by a single-chip microcomputer And it can adjust the pressure difference according to the pressure change, so that the infusion process is smooth and smooth. Since the air pump is used to provide pressure, the common way of using mechanical peristalsis to squeeze the infusion tube is canceled, so the common infusion tube can meet the needs, thereby reducing the use cost and improving the safety performance. In addition, an air purification device is connected to the air inlet of the air pump. When the air pump sucks the air in the atmosphere, the harmful bacteria and other dust and soot in the air can be sterilized and filtered through the air purification device before entering the infusion bottle. The internal clean gas will not pollute the liquid medicine and endanger the safety of patients. Moreover, the infusion pump is a desktop design, which can be placed freely and infused while moving, and is convenient and safe to use. However, in the Northeast or sub-zero temperature regions, the liquid may freeze during the infusion, or the liquid with a lower temperature entering the human body will cause discomfort to the body. Therefore, the infusion pump is not suitable for this environment.
