Infusion pump troubleshooting method and operation precautions
The infusion pump system is mainly composed of a microcomputer system, a pump device, a monitoring device, an alarm device, and an input and display device. The infusion pump is a mechanical or electronic control device that acts primarily on the infusion catheter to achieve the purpose of controlling the infusion rate. Here are some tips for the infusion pump troubleshooting and operation precautions, I hope to help everyone.
Infusion pump troubleshooting method
1. The flow of pressure is unstable. The cause may be air bubbles, need to be removed, or there is a foreign object in the check valve. The check valve can be removed, immersed in acetone, and ultrasonically cleaned. Sometimes there may be bubbles in the sand filter rod or partial blockage of tiny crystal grains or microbial growth of the salt. At this time, the sand filter rod is immersed in the mobile phase, ultrasonic bubbles are removed, or the sand filter rod (sheet) is immersed. The microorganism is quickly removed or dissolved in a dilute acid (such as 4 mol/L nitric acid) and washed immediately.
2. There is no flow phase out and no pressure indication. The reason may be that there is a large amount of gas in the infusion pump. At this time, the pressure relief valve can be opened, the pump can be operated at a large flow rate (5ml/min), the air bubbles can be drained, and a 50ml syringe can be used at the pump outlet. Drain the gas. Another reason may be that the seal ring is worn and needs to be replaced.
3. The reason for the high pressure is that the pipeline is blocked and needs to be cleaned or cleaned. The reason for the pressure drop may be a leak in the pipeline. Check for blockages or leaks can be done piece by piece.
Infusion pump operation precautions
When operating the infusion pump, do not touch the power plug with wet hands, and do not use it under direct sunlight or direct sunlight. The sensor plug must be tightly inserted during use, otherwise it will not work properly. When not in use, put it on the seat on the top of the infusion pump to lock it to avoid damage when moving and storing.
When charging, turn off the power switch before charging. If you use it again after first use or after a long period of inactivity, fully charge the battery before starting to use it. This infusion pump is not allowed to be stored in a place where it is directly blown by a cold (hot) air stream such as a fan, an air conditioner, an electric stove, a heater, or a humidifier.
The above is about the infusion pump troubleshooting method and operation precautions, I hope you understand the infusion pump troubleshooting methods and operational precautions, it is helpful to everyone.
